Green paint, the best choice for interior decoration!

Preface

The rapid development of the economy has brought a qualitative improvement in people’s lives.
Housing has also been transformed from adobe houses to small villas.
The interior decoration is becoming more and more beautiful and luxurious.
The proportion of interior decoration expenditure is increasing.
The people’s living environment is beautiful and comfortable.
The pursuit of degree is getting higher and higher.
With the continuous heating up of interior decoration, indoor environmental pollution caused by interior decoration has become more and more serious.
Related news reports have emerged one after another, which not only has a serious impact on the construction and decoration industries, but also brings inconvenience to consumers.

The consumer awareness of "harmless, environmentally friendly and green" has begun to com" href="">paint online coatingol.

Definition of green paint

Green coatings refer to energy-saving, low-polluting water-based coatings, light-curing coatings, powder coatings, and radiation-curing coatings, etc.

, that is, in the production of raw materials, product manufacturing, use or recycling, and waste treatment, the burden on the global environment is minimal and effective.

The development and trend of coatings

Coating is a mixture of polymer materials and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that adheres to the continuous coating film.

People began to use coatings more than 2000 years ago, and the coatings industry has become one of the criteria for judging the level of a country's chemical industry.
At present, coatings have evolved from chemical products, which emit volatile organic compounds, referred to as VOCs, to the air when they are dried to form films.
Such substances pose a serious threat to the human environment.
Especially when they are used in interior decoration, excessive VOC absorption by the human body can cause cancer, etc.
, and in serious cases, it can be life-threatening.
For this reason, countries around the world have formulated corresponding environmental regulations based on their own characteristics to limit the emission of VOCs in coatings.
Therefore, the development of green environmentally friendly coatings is a necessary trend for the development of the coatings industry and an important measure to reduce indoor environmental pollution.

At present, countries all over the world are strengthening the research and development of green and environmentally friendly paints.

According to data, the market for green decorative materials in developed countries accounts for 80%, while that of my country is only 12%, and the market price is relatively expensive.

To maintain human health and environmental safety.

Green paint should have the following characteristics: use less or no natural resources, and a lot of renewable resources; use low-energy manufacturing technology, use clean production technology, and minimize the emissions of the three wastes; in the product preparation or production process, do not use harmful Compounds are used as raw materials or additives; strictly control the release of coatings, prohibit the use of toxic and harmful solvents, products must have multi-functions such as antibacterial, anti-mildew, heat insulation, degaussing, anti-radiation, anti-static, etc.

The real green paint refers to the entire process of manufacturing, use and waste recycling.

It is not limited to governance, but starts from manufacturing.

Green paint is the focus of decoration

The biggest intersection between green paint and consumer groups is building decoration.

Since the concept of green environmental protection was put forward, green home decoration has attracted more and more attention.

high

Solid content solvent-based coatings reduce the solvent content and increase the solid content to meet environmental protection requirements.

Generally, the solid content of low solid content solvent-based coatings is 30%-50%, while the high solid content solvent-based (HSSC) requires a solid content of 65%-85% to meet increasingly stringent VOC restrictions.
In the formulation process, the use of some solvents that are not included in the VOC as diluents is a variation of strict restrictions, but at the same time it may bring other environmental protection or safety issues, which need to be considered comprehensively.

water

Water-based paint: Water is different from most organic solvents in that it is non-toxic, odorless and non-flammable.

The introduction of water into the paint can not only reduce the cost of the paint and the fire caused by the presence of organic solvents during construction, but also Greatly reduce VOC.

powder

Powder coating is a new type of solvent-free and 100% solid powder coating.
Theoretically, it is a zero-content VOC coating and is a relatively advanced coating in China.
The product recovery rate exceeds 95%, but the production process is relatively complicated, the cost is high, and the application is limited.
However, from the perspective of environmental protection, powder coatings are one of the main directions for future coatings development, but the technology and process need to be further studied .

In addition to the above-mentioned coatings, many new products have appeared on the market, such as low-VOC or zero-VOC coatings, insecticide, sterilization, odor absorption, negative ion release coatings, etc.
These coatings are all functional and environmentally friendly coatings and have broad development prospects.
With the improvement of people's awareness of environmental protection and the increasing demand for indoor health, the future development directions of coating science and technology are as follows:

(1) Water-based and environmentally friendly development.
The reduction of water-based coatings and the volatilization of compounds, reducing harm to the human body and the environment, improving the quality of water-based coatings, and developing new products are important measures to maintain the sustainable development of water-based coatings.

(2) Functional development.
Changes in the external environment will also bring about the diversified development of the indoor environment.
The coatings for home decoration have evolved from aesthetics to functionalization such as sterilization, insecticide, and anti-virus.
Although they have been used in fire prevention and heat preservation, they have been used in small areas.
There is still a certain distance from universalization, and performance and quality also need to be improved, so technology and cost input should be increased.

(3) Improve the level of process technology.
Although powder coatings have been developed with high recovery rates and high-performance coating products, due to process and technical limitations, problems such as high costs and low application penetration rates have been caused.
Green coatings should keep new product development in line with environmental protection requirements, and at the same time improve and improve the perfection and expansion of existing technologies, multi-line simultaneous progress, and improve the quality and level of architectural coatings.
