Plastic gold plate and manufacturing method thereof

Abstract

The invention relates to the field of plastic surface treatment processes, and specifically relates to a plastic gold plate and a making method thereof. The method comprises the following steps: spraying PP paint to the surface of an injection-molded plastic base material; putting the plastic base material spayed with the PP paint into vacuum coating equipment, and coating a film with volatile aluminum in a vacuum state, wherein the volatile aluminum is attached to the surface of the plastic base material to form a bright mirror surface; and after coating, taking out and spraying a layer of protective finishing paint to the surface of the coating. By adopting the method, acid washing is not needed, a series of procedures of brushing glue, foiling, sweeping the foil and polishing are avoided, the making procedures are greatly reduced, the manufacturing cost is reduced, the harm of massive dust produced in the production process to the body of a worker is avoided, the defective rate is reduced, the quality of a product is improved, and a good bright mirror surface effect can be achieved.

Description

technical field [0001] The invention relates to the field of plastic surface treatment technology, in particular to a plastic gold plate and a manufacturing method thereof. Background technique [0002] With the continuous improvement of plastic processing and modification technology, the application field is expanding rapidly. Different application fields have increasing requirements for plastic surface decoration, material protection, and improved adhesion. However, the structures and components of various plastic materials are different, and the corresponding surface properties are also significantly different. Various surface treatment technologies and products adapted to different applications have emerged as the times require. To meet the different needs of plastic surface treatment, a variety of treatment technologies have been developed. Commonly used techniques are: solvent cleaning (degreasing), corona treatment, short-wave ultraviolet radiation treatment, sandpa...

AI Technical Summary

Problems solved by technology

[0015] ① When pre-treating the injection molding substrate after pickling, the residual pickling solution on the surface cannot be wiped off with an ordinary white cloth, and even more lint and dust will be left, which will cause the product to be unable to be really cleaned and seriously affect the product Quality (e.g., paint pitting, and other blemishes);

[0016] ②At present, the glue is mostly applied by hand. After the gold foil or silver foil is pasted, there will be many glue lines, and the product is not uniform, which requires high glue workers. If the glue is too thick, it will cause discoloration of the gold foil. Uniformity will cause paint stripping and other problems;

[0017] ③Most of the products are pasted by hand with 9 pieces of gold foil, and there are gaps between each gold foil, which affects the appearance of the product, and because the foil paper is too thin, each product has many manual defects (gold foil cracking, gold foil oxidation, gold foil color is not uniform and many more questions);

[0018] ④ Sweeping the foil is to sweep away the overlapping part of the pasted gold foil with a mosquito net. When sweeping the foil, a large amount of foil dust will be generated, which will have a negative impact on the health of workers; at the same time, a large amount of foil dust will also have a serious impact on product quality (causing Particles), in addition, after sweeping the foil, the gold foil in the gap of each foil cannot be swept away. After the first topcoat is sprayed, the product surface will be seriously uneven, and the hands will be scratched;

[0019] ⑤ Most of the paint is artificially sprayed, and the uniformity is not well grasped, resulting in inconsistent product colors and uneven surface colors;

[0020] ⑥Grinding: There is a lot of dust, which will cause damage to the workers' bodies. The grinding is manual, which cannot achieve uniformity of each product. The degree of grinding varies. There is a lot of dust on the polished product, which is difficult to wipe clean
