[0012] Example 1.
[0013] The preparation method of powder coating includes the following steps,
[0014] (1) In parts by weight, mix 40 parts of aliphatic glycidyl ether epoxy resin, 10 parts of poly(meth)acrylic resin with free carboxyl groups, 2 parts of magnesium carbonate, 5 parts of rubber powder, 10 parts of carbon black, Mix 2 parts of aluminum powder, 0.3 parts of dibutyl tin dilaurate, and 3 parts of leveling agent to obtain Mixture A.
[0015] (2) Mix 20 parts of bisphenol F epoxy resin, 3 parts of iron oxide red, 30 parts of anti-slip and wear-resistant powder, 3 parts of curing agent, and 0.7 parts of stabilizer to obtain Mixture B.
[0016] (3) Use a twin-screw extruder at the front end to extrude Mixture A at 70°C -80°C, increase the temperature of the extruder to 120°C -130°C in the middle section, then add Mixture B, and extrude. Powder coating is obtained after pulverization.
