    Core tip: paint itself has a long history, China is the first country in the world to use natural resin as film-forming material paint

    The mineral color used by early painters was formulated by water suspension or water or albumin, which was the earliest water-based paint

    There is a long history in the production and use of coatings by human beings, which can be generally divided into three development stages: the use of natural film-forming substances, the formation of coating industry and the production of synthetic resin coatings

    The paintings of amitamila caves in Spain, the rock walls of Lasco caves in France and the remains of Yangshao culture in China Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint

    In fact, there is no ugly color in the wall paint, only the disharmonious color matching

    The use of wall color contains the knowledge of health

    Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health

    Grasp the basic principles of wall color and paint a colorful space

    1、 Wall paint color selection notice 1

    Light color is generally used for the top surface

    Light colors make people feel light, dark colors make people feel heavy

    Usually, the treatment of rooms is from top to bottom, from shallow to deep

    For example, the ceiling and walls of rooms are white and Paint Home News: paint itself has a long history, China is the world's first country to use natural resin as a film-forming material paint

    The mineral color used by early painters was formulated by water suspension or water or albumin, which was the earliest water-based paint

    There is a long history in the production and use of coatings by human beings, which can be generally divided into three development stages: the use of natural film-forming substances, the formation of coating industry and the production of synthetic resin coatings

    According to a large number of archaeological data, such as the paintings of amitamila caves in Spain, the paintings of the rock walls of Lasco caves in France, and the painted patterns on the residual pottery pieces of Yangshao culture in China, etc., in the Neolithic Age of 5000 B.C., people used the fat of beasts, the juice of grass and trees, as well as natural pigments to prepare the original painting materials, and used feathers, branches, etc

    for painting

    In 1855, British A

    parks obtained the patent right to use nitrocellulose (nitrocellulose) to make coating, and established the first factory to produce synthetic resin coating

    In 1909, L.H

    Baekeland, an American chemist, succeeded in the trial production of alcohol soluble phenolic resin

    Later, K

    Albert of Germany successfully studied the rosin modified oil soluble phenolic resin coating

    After the first World War, in order to open up the market of excess nitrocellulose and meet the needs of automobile production and development, good solvents such as butyl acetate and ethyl acetate were found, and the construction method of air spraying was developed

    The production of nitrocellulose coating reached a climax in 1925

    At the same time, phenolic resin coating is also widely used in wood furniture industry

    In the production of color paint, the wheel mill is gradually eliminated, and the ball mill, three roller machine and other mechanical grinding equipment are widely used in the paint industry

    In 1927, R.H

    keener of General Electric Company of the United States broke through the alcoholysis technology of plant oil and invented the process of preparing alkyd resin with dry oil fatty acid

    Alkyd resin coating developed rapidly into the mainstream of coating varieties

    It broke away from the traditional method of refining coating with dry oil and natural resin, and created a new era of coating industry

    By 1940, melamine formaldehyde resin and alkyd resin cooperated to make paint, further expanded the application scope of alkyd resin paint, developed into the main type of decorative paint, widely used in industrial coating

    After the Second World War, the varieties of synthetic resin coatings developed rapidly

    American, British, Dutch (shell) and Swiss (Ciba) first produced epoxy resin in the late 1940s, providing new raw materials for the development of new anti-corrosion coatings and industrial primers

    In the early 1950s, the polyurethane coating with wide performance was put into industrial production in the German fabenberg company

    In 1950, DuPont company of the United States developed acrylic resin coating, which gradually became the main type of automobile coating, and expanded to light industry, construction and other departments

    After the Second World War, there was a surplus of styrene butadiene latex, and the United States actively studied the use of styrene butadiene latex for water emulsion coating

    In the 1950s-1960s, polyvinyl acetate latex and acrylate latex coatings were developed, which are the largest varieties of architectural coatings

    In 1952, knasack grissin company of Germany invented the thermoplastic powder coating of vinyl resin

    Shell chemical developed the epoxy powder coating

    In 1961, Ford Motor Company developed Electrodeposited coatings and realized industrial production

    In addition, in 1968, the Federal German company Faber Bayer first sold the light curing wood paint on the market

    Latex coating, water-soluble coating, powder coating and light curing coating have greatly reduced the amount of organic solvent in the coating products, even without the use of organic solvent, opening up a new field of low pollution coating

    With the development of electronic technology and aerospace technology, organic resin coating, which is mainly composed of organosilicon resin, developed rapidly in the 1950s-1960s and occupied an important position in the field of high temperature resistant coating

    In this period, the industrial production of heterocyclic resin coating, rubber coating, vinyl resin coating, polyester coating, inorganic polymer coating, etc

    With the development of synthetic resin coating, large-scale resin reactor (see reactor) is gradually used, and efficient grinding equipment is gradually used in the grinding process, such as high-speed disperser and sand mill, which has been popularized and replaced the three roller mill in the 40-50's

    In order to cooperate with the popularization and application of synthetic resin coating, the coating technology has also undergone fundamental changes

    In 1950s, high pressure airless spraying was widely used in shipbuilding industry and steel bridge construction, which greatly improved the working efficiency of coating

    Electrostatic spraying was developed in 1960s

    It is suitable for large-scale assembly line coating and promotes the further promotion of powder coating

    Electrodeposition coating technology was developed in the 1960s to adapt to the emergence of water-soluble coatings, especially after ultrafiltration technology solved the wastewater problem of electrodeposition coating, it further expanded the application field

    Since 1973, due to the impact of the oil crisis, the coating industry has been developing in the direction of saving resources and energy, reducing pollution, benefiting ecological balance and improving economic benefits

    The development of high solid coating, water-based coating and powder coating, as well as the development of low energy consumption curing varieties such as radiation curing coating, are its specific performance

    In 1976, a new type of electrodeposited coating, cathodic electrodeposited coating, developed by Pittsburgh flat glass industry company of the United States, improved the anti-corrosion ability of automobile body and was rapidly promoted

    In 70s, organic-inorganic polymer emulsion was developed and applied to architectural coatings and other fields

    Functional coatings (see coatings) have become a research topic in the coatings industry in the 1970s, and a series of new varieties have been introduced

    In the 1980s, various architectural coatings developed rapidly

    The computer has been used in the production, testing and management of coatings

    Robot (manipulator) has been widely used in special or dangerous situations instead of manual painting

    This stage has the following characteristics: ① under the guidance of modern scientific theory, the research and development work has been carried out purposefully, and the development process has been accelerated

    For example, the theory of modern chemistry has been applied in the coating industry, and the coating additives have been widely used, so that the product performance and production efficiency of the coating industry have been greatly improved

    ② With the methods of copolymerization, modification and mixing, the varieties of synthetic resin with characteristics are increasing day by day, the properties of coatings are improved, and the varieties of functional coatings are increasing day by day

    ③ The test of coating quality has changed from the measurement of surface phenomena to the measurement of internal quality of coating

    For example, more attention has been paid to the measurement of molecular weight and molecular weight distribution of synthetic resin to understand the quality of synthetic resin, and the production of products is guided by the observation of the microstructure of coating film with SEM

    It is believed that with the continuous progress of science and technology, the production and development of coatings will reach a new historical period, that is, the period of synthetic film-forming materials

    Now there are thousands of brands of coatings, among which there are some coatings with special functions, such as fire retardant coatings, nuclear radiation resistant coatings, infrared camouflage resistant coatings, etc., which can be said to have everything

    At present, the coating industry is moving to a new stage, which is in the direction of saving resources, energy, environmental protection and conducive to ecological balance
