Embodiment 1
[0032] A plastic surface treatment process, the specific steps are as follows:
[0033] (1) Degreasing: Soak the plastic to be treated in the degreasing solution for 0.4h and take it out;
[0034] (2) Coarsening: Soak the degreased plastic in step (1) in the roughening pretreatment solution, take it out after soaking at 23°C for 5 minutes, transfer it to the roughening solution, and take it out after soaking for 0.5 hours;
[0035] (3) Surface neutralization: Take out the plastic in step (2) and soak it in the neutralizing solution; the neutralizing solution is a 30% sodium hydroxide aqueous solution;
[0036] (4) Surface catalysis: Soak the plastic obtained in step (3) in the catalytic solution, soak it at 65°C for 15 minutes, take it out, wrap its surface with a plastic film, and let it stand for 3 days under natural conditions;
[0037] (5) Make a liquid wear-resistant layer: take m-p-cresol, phenolic resin, maleic anhydride grafted, polyoxymethylene, surfactant, wear-resi...
