Embodiment 1

[0021] A surface treatment method for a plastic chair, comprising the following steps:

[0022] S1, annealing the plastic chair;

[0023] S2, degreasing the annealed plastic chair;

[0024] S3, de-staticize and de-dust the degreasing-treated plastic chairs;

[0025] S4, treating the surface of the plastic chair treated in step 3 so that its surface flatness is 0.5mm;

[0026] S5, spray primer on the surface of the plastic chair, then dry;

[0027] S6, then spray the topcoat again, after the topcoat is naturally leveled on the surface, then spray the topcoat;

[0028] S7, then dry and cure the plastic chair at a temperature of 60°C for 8 minutes, and then dry at a temperature of 30°C until the moisture content is 4%.

[0029] In the step 1, the plastic chair is heated to 50°C and kept for 1.5h.

[0030] In said step 2, clean the plastic chair with gasoline or alcohol, then rinse its surface with pure water, and finally dry it at room temperature.

Abstract

The invention belongs to the technical field of plastic products, in particular to a surface treatment method of a plastic chair. The surface treatment method comprises the following steps that the plastic chair is subjected to annealing treatment; the plastic chair subjected to annealing treatment is subjected to oil removal treatment; the plastic chair subjected to oil removal treatment is subjected to electricity removal and dust removal treatment; the surface of the plastic chair treated in the step 3 is treated, and the surface evenness of the plastic chair ranges from 0.5 mm to 1.5 mm; undercoat is sprayed to the surface of the plastic chair, and then drying is carried out; then finishing coat is sprayed, and after the finishing coat is naturally leveled on the surface, finishing coat is sprayed in a spot manner; and then the plastic chair is dried and cured for 8 min to 10 min at the temperature ranging from 60 DEG C to 80 DEG C, and then the plastic chair is dried at the temperature ranging from 30 DEG C to 50 DEG C till the water content ranges from 4% to 6%. According to the surface treatment method, sufficient coloring can be achieved, and meanwhile any organic solvent or components thereof can be reduced to the greatest degree or eliminated.

Description

technical field [0001] The present invention relates to the technical field of plastic products, in particular to a surface treatment method for plastic chairs. Background technique [0002] Plastic is a class of plastic synthetic polymer materials. Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials that are indispensable in today's daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, adding various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure, and maintains the same shape at room temperature. The plastic products industry is the pillar industry of my country's light industry. At present, my country's plastic products industry is facing opportunities for development, but it will also encounter many challenges. This needs to be dominated by the market and enterprises, and the government is providing policy guidance...
