Embodiment 1

[0032] Take the following raw materials by weight:

[0033] thermoplastic acrylic resin 40g

[0034] Acrylic resin copolymer 20g

[0035] Isobutylated Melamine Formaldehyde Resin 38.5g

[0036] BFK-G 1.5g

[0037] BYK333 0.2g

[0038] BKY141 0.3g

[0039] DBE 2.5g

[0040] Epoxy resin 5g

[0041] The above-mentioned weighed raw materials are mixed uniformly according to the conventional method to make a paint, and then the paint is coated on a magnesium alloy sample surface in the same way as other paints, and then baked at a temperature of 150 ° C for 20 minutes. Then check the generated paint film layer, the test results are shown in Table 1, wherein, the adhesion is tested by 100 grids, and the test process of the damp heat cycle experiment is: place at -35°C for 1h, heat up to 70°C and humidity 95% after 1h Place it for 1 hour, and then return to -35°C for 1 hour as a cycle, a total of 15 cycles, and the adhesion is tested by 100 grids.

Description

technical field [0001] The invention relates to a coating material, in particular to a paint for coating metal surfaces. Background technique [0002] Paint refers to a type of film-forming substance that can dry and form a film when applied to the surface of an object, making the object beautiful and protected, or forming a film with other special functions on the surface of the object. Paint is a multi-component system, generally a viscous liquid. Since the function of paint is to protect different surfaces and environments, it needs to have mechanical strength, aging resistance, and corrosion resistance. [0003] There are many kinds of paints produced in my country, but they all belong to common products, which are far from meeting the needs of the development of my country's high-tech industry, especially in the field of metal anti-corrosion. Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. F...
