Description

technical field [0001] The invention relates to the field of automobile engine oil pan materials, in particular to an energy-saving and environment-friendly coating for the automobile engine oil pan. Background technique [0002] Acrylic resin is a resin made by the copolymerization of acrylate, methacrylate and other olefinic monomers. Compared with other synthetic polymer resins, acrylic resin has many outstanding advantages, such as excellent light resistance, weather resistance, and UV resistance. It is not easy to decompose and turn yellow when exposed to light, and can maintain the original luster and color for a long time. It has good heat resistance, good resistance to acid, alkali, salt, grease and detergent and other chemical stains and corrosion properties, and excellent flexibility. and minimal pigment reactivity. Therefore, it is widely used in industries such as automobiles, home appliances, metal furniture, coil industry, instrumentation, construction, textil...

Problems solved by technology

[0003] However, the linear structure of acrylic resins leads to the disadvantages of hot stickiness, cold brittleness, anti-sticking and poor heat resistance, which limit its application range.

The homogeneous structure of acrylic resin makes it difficult to balance its cold resistance and heat resistance. If you want to increase the low temperature resistance, you will lose the high temperature resistance, and vice versa. Therefore, ordinary acrylic finishing materials inevitably have the above shortcomings.
