With the continuous improvement of people's requirements for the quality of life, people's awareness of environmental protection continues to improve, people's requirements for living space and living environment are also higher and higher, the health and environmental protection in home decoration is more widely concerned. After the epidemic, more and more consumers realize the importance of a healthy and environmentally friendly home environment for human health. As an important space for people's long-term life, building a healthy and livable home environment is very important for people's physical and mental health.
As we all know, coating is an important part in the process of home decoration. The quality of wall coating directly affects people's quality of life. Professor Qian Jun, doctoral supervisor of School of materials science and engineering, East China University of Science and Technology, and Jiao Yi, member of expert group of Shanghai interior decoration industry association, shared with us on Relevant Issues of coatings.
Coating is a kind of fluid dynamic material, which is dried or solidified by a simple construction method and firmly covered with a uniform film on the surface of the object. Such fluid dynamic material is called coating. The coating can be liquid or powder.

Is functional coating really effective
It can be seen that a lot of coatings on the market are publicized to be effective in antibacterial, moisture-proof, mildew proof and so on. Generally speaking, which functional coatings are there now? Are they really effective?
Jiao Yi said: "at present, the main functional coatings are moisture-proof, mildew proof, crack resistant, antibacterial, formaldehyde adsorption, and easy to scrub. Of course, in order to achieve the good functionality of the top coat, we should not only pay attention to the surface of the top coat, but also match with high-quality putty and primer to deal with the problems of the exterior wall, so as to better realize the function of the top coat. For example, a better coating product that is easy to clean can be as new as 10 years. "
Two experts focused on sharing with you antibacterial functional coatings. "In addition to being waterproof and mildew proof, some regular brand coatings do have antibacterial properties to a certain extent and can inhibit certain bacteria. It is better to use antibacterial coatings at home than not," said Jiao Yi Professor Qian also said: "in addition to waterproof and mildew resistant coatings, some coatings do have certain antibacterial properties. Its principle is mainly to add some antibacterial additives or auxiliary materials to the coating, such as ZnO Composite Antibacterial agent, silver carrying antibacterial agent, modified zinc type antibacterial agent, organic antibacterial agent, etc. Generally speaking, the antibacterial effect of organic antibacterial coating is better, but the antibacterial materials will generally decrease with the increase of time, and its antibacterial performance is related to the time and the environment. "
For example, sankeshu (Jingwei 360 antibacterial wall paint) can effectively resist up to 19 kinds of bacteria and molds, with an antibacterial rate of more than 99%; and it meets the requirements of the limit of biocides in GB / T 35602-2017 green product evaluation coating.

Basic principles of coating selection
Coatings have so many functions and brands. How should citizens choose coatings for home decoration?
In the choice of coatings, both experts mentioned that it is necessary to choose a regular brand. "When choosing the coating, we can see whether the coating has" German blue angel "and" European flower "certification. Generally speaking, these standards are internationally certified, which can effectively ensure the environmental protection of the coating," said Jiao Yi So people can pay attention to the relevant small signs when choosing. At the same time, Professor Qian suggested that the public should pay attention to the VOC content of coatings and the types of organic compounds in VOC, such as benzene, formaldehyde, etc.
Secondly, the function of coating should choose the right product from its own needs, not the more functions the better. If you want to decorate a children's room, you can choose children's paint. Generally speaking, children's paint will be more scrub resistant and more colorful. If you want to choose dark paint for matching if you have high requirements for design sense, experts also said that there is no special definition about the rumor that light paint is better than dark paint, which can be completely determined according to your own preferences and decoration style. Of course, as the dark paint needs multi-layer brushing, it is recommended to choose a better primer, so the effect will be better.

Finally, Jiao Yi suggested that when making home decoration painting, we should not only select a good paint, but also select a qualified and experienced construction team with good reputation, equipped with high-quality construction and high-quality painting tools to achieve good results.
In a word, when choosing coating, the public must choose a regular brand, and then see whether it is a pure flavor coating, whether it has environmental protection signs, whether it indicates to add some good deodorant, such as bamboo charcoal, seaweed, etc., and select a high-quality construction team. Of course, the most important thing is to choose the coating according to your own needs.
