Functional coatings welcome development opportunities

Some paint companies have realized that there is not much room for development for serious excess ordinary decorative paints, and functional paints will usher in a beautiful spring. Paint companies are also trying their best to enter new fields.

Internal wall energy-saving warm coating is a new topic in the field of building energy conservation in the world today. The interior wall energy-saving and heat preservation paint developed by Hainan Redwood Science and Technology Co., Ltd. has recently passed the evaluation of related scientific and technological achievements of the Ministry of Housing and Urban-Rural Development, which fills the gap in this domestic technology. This kind of energy-saving warm coating, not only plays a decorative role on the wall, but also can improve the indoor temperature, saving energy costs such as coal and gas.

According to the person in charge of the Department of Evaluation and Promotion of the Science and Technology Development Promotion Center of the Ministry of Housing and Urban-Rural Development, this is the first internally developed energy-saving thermal insulation coating in China. It is based on the principle of reflection and heat preservation of interior walls and is made of new raw materials containing nano-composites. After the paint is applied on the surface of the inner wall, the coating has a high reflectivity to the mid-far infrared wave in the room. At the same time, the hollow microspheres in the coating have a certain thermal barrier effect, which can reduce the heat loss, thereby increasing the indoor temperature and greatly reducing the heating energy consumption in winter. It is very green and environmentally friendly.

In order to develop this product, the Hainan Hi-Tech Corporation Hainan Redwood Science & Technology Co., Ltd. invested heavily and successively cooperated with China Academy of Building Research and China Academy of Building Materials Science and other research institutes to hire a number of domestic building energy-saving coatings. Experts form a research and development team and set up a building energy-saving R&D center. After more than two years of repeated research and experiments, the experts eventually developed a successful new product with domestic significance and applied for 15 invention patents.

Coincidentally, Shandong Pentium Paint Co., Ltd. also developed a breathable paint. According to the company’s general manager, Mr. Gu Shigang, the paint has sponge-like colloidal negative ions that can adsorb toxic and harmful gases and convert it into effective oxygen after being filtered in a timely manner, just like a forest oxygen bar. Once the company’s products were launched, they were welcomed by consumers, used by some large real estate projects, and exported to Mongolia.

Shandong Liandi Paint Co., Ltd. has launched a self-cleaning coating this year. At the same time, it is developing anti-icing coatings, anti-snow coating and high-temperature anti-adhesion coatings. Dai Maozhen, chairman of the company, told reporters that a variety of functional coatings have broken the paint's decorative conventions. Under different environmental requirements, various kinds of coatings have shown great promise. Self-cleaning paints are made of nano-structured materials and PIN technology. The extremely low surface tension of nanomaterials enables it to have strong hydrophobic and oil-repellent capabilities, reducing the surface area of ​​dust and objects by 90%, and providing superior automatic cleaning characteristics.

Dai Maozhen introduced that auto glass is prone to freezing in cold, rainy and snowy weather in winter, and has become the culprit in traffic accidents. Applying a layer of anti-icing and anti-icing paint over the car's glass will allow the driver to maintain a good vision and facilitate safe driving in cold weather. The high-temperature anti-adhesive coating can withstand high temperatures up to 2000°C. It has the characteristics of small coefficient of friction, easy sliding, strong repulsive force and self-cleaning properties. It can be painted on the surfaces of various high-temperature smelting equipments to prevent the adhesion of various high-temperature solutions. Attached.

Yan Yongjiang, secretary general of the Shandong Coatings Industry Association, said that the functional paints have broad prospects for development. Anti-mosquito coating, anti-static coating, anion coating, anti-fouling coating, energy-saving warm coating, etc. are all paint companies starting from the actual situation and jointly researching products of large and medium-sized schools. They are showing their skills in the field of functional coatings.

Yan Yongjiang told reporters that now the market for ordinary paint is fiercely competitive, and profits have been squeezed close to zero. It can be said that there is no improvement. To this end, the Shandong Coatings Industry Association requested the province's paint companies to enter the field of functional coatings. Shandong Pentium Paint, Shandong Liandi Paint Industry, Shandong Qilu Paint Industry and Shandong Lehua Paint Industry Co., Ltd. have developed in a short time. The featured functional coating avoids vicious competition in ordinary coatings.
