Does water-based paint take advantage of green innovation to open the application market?

With the continuous improvement and reform of China's environmental protection laws and regulations, if relevant personnel want to reduce the VOCs emissions of volatile organic compounds, they must strengthen the development of green coatings, and only in this way can they ensure the smooth development of follow-up work
.
It can be seen that more and more construction machinery companies are beginning to apply water-based paints, and in the future social development, water-based paints will gradually replace oil-based paints, which will become the inevitable trend of future industry development
.
From another point of view, water-based paint is a kind of paint that contains a very small amount of organic solvent, which uses water as a diluent, and uses a small amount of low-toxic alcohol ether organic solution, and does not contain toluene, xylene, etc.
Substances harmful to the human body
.
Under normal circumstances, the organic solution of water-based coatings needs to be kept between 5%-15%, which has a very important effect and effect on reducing pollution and saving resources, and even improves the surrounding working environment and reduces air pollution
.
Green paint is the general term for low-pollution (or non-pollution) and low-toxic (or non-toxic) coatings, also known as "environmental-friendly coatings"
.
This kind of paint causes relatively little harm to the ecological environment
.
In order to achieve its goal, after many years of careful research by global and domestic scientific research institutions, coatings professional research institutions, and corporate R&D personnel, water-based coatings have come out and have gradually begun to be applied in the fields of smart terminals, 3C digital and non-mobile phones
.
The advantages of water-based coatings are as follows: 1.
Saving energy, eliminating fire hazards during construction, and reducing environmental pollution are also the main directions for the development of manufacturing coatings in the future
.
2.
Water-based paint uses water to replace organic solvents in traditional solvent paints, thereby reducing the VOC content of the paint.
Compared with high-solid paints, the organic solvents in water-based paints are greatly reduced.
Compared with powder coatings, the production of water-based paints The equipment is relatively simple, saves energy, does not require high energy consumption, and has significant environmental protection features
.
3.
It can be directly coated for construction operation in a relatively humid environment;4.
Electrophoretic coating can be used to make the coating film uniform, smooth, good spreadability, and excellent protection; 5.
Coating tools can be washed with water to reduce the consumption of cleaning solvents; 6.
Safe, non-flammable and non-explosive; water-based The lack of paint is as follows: 1.
It is difficult to obtain a high gloss and high fullness paint film; 2.
The latent heat of water evaporation is high, which is slower than many solvents.
It is necessary to extend the drying time or increase the baking temperature.
When the paint film dries by itself, When the ambient air humidity is high (greater than 80%), it will obviously affect its drying speed; 3.
Some resins used in paint preparation are easy to hydrolyze and are more sensitive to other components, causing precipitation and gelation, which affects the storage and use performance of the coating and needs to be optimized Special storage equipment; 4.
The high surface tension of water makes it difficult for the coating to wet the substrate.
The dirt on the substrate surface is easy to cause shrinkage in the coating film.
During the construction process, the cleanliness of the surface of the material is required.
High; At present, foreign giants and domestic leading paint companies have also begun to focus on the deployment of water-based paints and more green paints.
This is also the trend of future development.
Green innovative design must also start from the green material carrier to comprehensive cross-border thinking.
The material is design The source, a good green innovative design is inseparable from more new environmentally friendly materials
.
Green environmental protection materials, green innovative design, and green thinking are important development trends and driving forces in the new blue ocean market of the Internet of Everything in the 5G era
