Acrylic resin is made by copolymerization of (meth)acrylates and other vinyl monomers. Acrylic resin has light color and good transparency; strong weather resistance, resistance to ultraviolet light, not easy to decompose or turn yellow, good gloss and color retention; no decomposition or discoloration at 170 ℃, at a temperature of about 230 ℃ or higher Still does not change color. Acrylic resin coatings have good resistance to acid, alkali, salt, grease, detergents and other chemical contamination and corrosion performance, as well as excellent construction performance. Acrylic resin coatings are the mainstream products in industrial coatings, and the largest market is car coatings.
In addition, acrylic resin coatings are widely used in light industry, home appliances, metal furniture, aluminum products, coil industry, instrumentation, construction, textiles, plastic products, wood products, papermaking and other industries. Acrylic resin has become one of the backbone resins in my country's coating industry. Although acrylic resin has many of the above advantages, it is widely used, but its performance still does not reach people's expectations. For example, the critical surface tension of acrylic resin is a medium-high value among coating resins, reaching 41 mN/m, which is much higher than that of fluorocarbon resin (such as the critical surface tension of polytetrafluoroethylene is mN/m). It has poor water and oil repellency and is anti-corrosive The performance is not strong, and the weather resistance is far inferior to that of fluorocarbon resin. Modifying with fluorine materials, hoping to further improve the quality of acrylic resin, and continue to expand its use, is one of the important topics in the coatings scientific research community.
