[0020] Example one
[0021] A surface treatment method of a plastic chair includes the following steps:
[0022] S1, annealing the plastic chair;
[0023] S2, degrease the annealed plastic chair;
[0024] S3: De-energizing and dust-removing plastic chairs that have undergone degreasing treatment;
[0025] S4: Process the surface of the plastic chair processed in step 3 to make the surface flatness 0.5mm;
[0026] S5, spray primer on the surface of the plastic chair, and then dry;
[0027] S6, then spray the top coat to make the top coat level naturally on the surface, and then spray the top coat;
[0028] S7, the plastic chair is then dried and cured at a temperature of 60°C for 8 minutes, and then dried at a temperature of 30°C to a moisture content of 4%.
[0029] In the step 1, heat the plastic chair to 50°C and keep it for 1.5 hours.
[0030] In the step 2, the plastic chair is cleaned with gasoline or alcohol, then the surface is rinsed with pure water, and finally dried at room tempera...
