Common knowledge of coatings: characteristics and advantages of waterborne floor coatings

Core tip: floor coating has many characteristics, such as no joint, good overall decoration, smooth surface, easy cleaning, excellent physical and mechanical properties and chemical resistance, moderate price, simple construction, convenient maintenance, etc In addition, the floor coating can also give the floor anti-static, anti impact spark, high temperature resistance, anti-skid and other special functions according to the special needs Compared with other floor materials, it can meet the different requirements of modern industrial production for the floor Based on these characteristics, modern buildings, especially modern industrial workshops, such as food processing, pharmaceutical, mechanical electronics, instrumentation, chemical, aviation, automobile and other industries Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings: floor coating has many characteristics such as no joint, good overall decoration, smooth surface, easy cleaning, excellent physical and mechanical properties and chemical resistance, moderate price, simple construction, convenient maintenance, etc In addition, the floor coating can also give the floor anti-static, anti impact spark, high temperature resistance, anti-skid and other special functions according to the special needs Compared with other floor materials, it can meet the different requirements of modern industrial production for the floor Based on these characteristics, modern buildings, especially modern industrial workshops, such as food processing, pharmaceutical, mechanical and electronic, instrumentation, chemical, aviation, automobile and other industries, use a lot of floor coatings At present, more than 80% of floor coatings in China are solvent-based coatings, the rest are mainly solventless epoxy coatings and polyurea spray coatings, and the proportion of waterborne floor coatings is very small Solvent based floor coatings contain more organic solvents, which are discharged into the air during the production and construction of the coatings, polluting the environment and endangering human health; in addition, the solvent based polyurethane floor coatings also contain free isocyanate monomer, which will seriously affect human health and living environment in the construction process However, there are a few active diluents in the solventless epoxy floor coating The commonly used active diluent is butyl epoxypropyl ether, which has certain toxicity, high cost and still contains a certain amount of volatile organic solvent There are still many insurmountable disadvantages in the actual construction of solvent based floor coating, such as blistering, bubbling, falling off, poor adhesion, etc., which will be affected by the environmental temperature and humidity, the base humidity, and other problems of the base surface, especially the drying degree of the base material is required to be very high, but it is difficult to meet the requirements in the actual construction The water-based floor coating has low requirements on the drying degree of the base material, the construction tools can be washed directly with water, the preparation and construction operation of the coating are safe and convenient, and the coating is non combustible, non explosive, safe and convenient for storage and transportation, avoiding explosion and fire accidents caused by improper storage, transportation and use of solvent based coating Water based floor paint has the characteristics of green, energy saving, safety and convenient function, which has been developed rapidly in the world As a pure environmental protection product diluted with clear water, waterborne floor paint is a new generation of high-tech sunrise product, which has the characteristics of low formaldehyde and low aromatic hydrocarbon compared with traditional solvent floor paint Many people do not understand the water-based floor paint, can not get rid of the misunderstanding of solvent based floor paint, think that the water-based floor paint is not as good as solvent based floor paint In fact, water-based floor paint can dilute the water without dissolving the film-forming substances Solvent based floor paint is dry film-forming, parallel film-forming, water-based paint is polymer film-forming, dense pattern film-forming, the latter is the real high-grade paint film, belonging to high-tech products There are five major differences between water-based floor paint and common paint: 1 Water-based floor paint is based on a variety of high molecular epoxy resin, water is the dispersion medium, and special additives are added to make organic matter (filler pigment The traditional paint is made up of vegetable oil and synthetic resin as the main film-forming material, supplemented by various auxiliaries and pigments There are a large number of 15 series and several varieties When used, organic solvents such as toluene and xylene must be added 2 The paint film of water-based floor paint can be divided into matte, bright and high gloss It has good alkali resistance, acid resistance, weather resistance, salt resistance, water resistance, flame retardant, fast drying time, large coverage area, good anti rust and anti-corrosion performance, rust and anti rust function, good combination with each paint and no reaction; the traditional paint film is bright and hard, water resistance, weather resistance, chemical resistance, electrical insulation The paint film is brittle, dry for a long time, and yellowing is easy for low-grade paint film Different paints are not suitable for combination due to their different properties 3 The water-based floor coating is widely used in wood, metal, ship, cement, automobile and other surfaces, especially in pipeline, equipment anti-corrosion, anti rust, etc.; the traditional paint is suitable for different occasions and environments according to different characteristics 4 The adhesion of waterborne floor paint is higher than that of common paint, which can reach 1-2 level; the adhesion of traditional paint is 2-3 level 5 The surface dry time of water-based floor paint is 20 minutes, and the actual dry time is 15 hours; the surface dry time of traditional paint is 2 hours, and the actual dry time is more than 30 hours Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
