Abstract
The invention discloses a surface gold-plating method for a plastic product, and relates to the technical field of plastic product manufacturing. The surface gold-plating method comprises the following steps: cleaning the surface of the plastic product; removing kinds of impurities, stains and static electricity attached to the surface, drying and removing moisture on the surface of the plastic surface; spraying a base coat on the surface of the plastic product; drying the surface, sprayed with the base coat, of the plastic product; putting the processed plastic product into a vacuum environment; heating a metal filament, evaporating and condensing on the surface of the plastic product to form a metal film; spraying a finish paint on the surface, plated with the metal film, of the plastic product, wherein the thickness of the finish paint is 5-10 microns; carrying out drying treatment on the plastic product sprayed with the finish paint, so that the finish paint is completely dried; and the procedures for plating the metal film on the surface of the plastic product are completely finished. According to the surface gold-plating method for the plastic product, the problem of the surface of the plastic product can be solved.
Description
Technical field
The present invention relates to plastics manufacturing technology field, especially a kind of method at surface of plastic products metallizing.
Background technology
In daily life, the purposes that the product that can make of a lot of plastics replaces five metals metalloid product to have, but the product still preferred in the subconsciousness of people with there being metal-like., such as mobile phone, computer and automobile etc. field, at surface of plastic products plating layer of metal film, not only can increase the attractive in appearance of plastics, intensity, electroconductibility, also wear resistance and the hardness of plastics can be improved, therefore, manufacturer needs to adopt certain surface treatment process method, plating processing is carried out on the surface of plastics, plate layer of metal film (as to aluminize, zinc-plated, copper facing, silver-plated, gold-plated, chromium plating etc.), tradition adopts the method for similar chemical plating and water power plating processing to surface of plastic products electroplating processing method, and these two kinds of electroplating process exist the use of heavy metal ion and the situation of remnants, environment are caused to the problem of comparatively serious pollution.
Summary of the invention
The object of this invention is to provide a kind of surface of plastic products method for plating metal, it can solve the problem that conventional plating process causes environmental pollution.
In order to solve the problem, the technical solution used in the present invention is:
This surface of plastic products method for plating metal, comprises the steps:
A, cleaning: clean surface of plastic products, remove all kinds of impurity of its surface attachment, spot and electrostatic, and carry out drying, eliminates the moisture of surface of plastic products;
B, spray base: carry out spray base in surface of plastic products, base coat thickness 10 ~ 20 μm;
C, oven dry: the surface of plastic products being sprayed with priming paint is dried;
D, vacuum metallization: vacuum environment put into by plastics step C handled well, heating of metal filament makes it evaporate and condenses in surface of plastic products to form metallic film;
E, topcoating: surface of plastic products spray paint D step being coated with metallic film, finish paint thickness 5 ~ 10 μm;
F, baking finish paint: plastics E step being sprayed with finish paint carry out drying treatment, make finish paint complete drying, so far, all terminate in the operation of surface of plastic products metal-coated films.
Further: in described spray base step, described priming paint is any one of polyurethane coating, epoxy coating, amido coatings or acrylate paint.
Further: in described topcoating step, described finish paint is any one of acrylate varnish, polyester varnish or polyurethane lacquer.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention can avoid heavy metal ion remaining, reduces the probability of contaminate environment, save energy.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
Embodiment:
This surface of plastic products method for plating metal, comprises the steps:
A, cleaning: clean surface of plastic products, remove all kinds of impurity of its surface attachment, spot and electrostatic, and carry out drying, eliminates the moisture of surface of plastic products, improves the paint film adhesion on plastics device surface;
B, spray base: carry out spray base in surface of plastic products, can use hand spray or automatic spraying operating during spray base, attentional manipulation priming paint film thickness 10 ~ 20 μm, requires primer coating to have higher hardness and have the performance can modifying plastics defect; Priming paint can select any one of polyurethane coating, epoxy coating, amido coatings or acrylate paint;
C, oven dry: the surface of plastic products being sprayed with priming paint is carried out drying and processing, improve the sticking power of metallic film in surface of plastic products;
D, vacuum metallization: vacuum environment put into by plastics step C handled well, heating of metal filament makes it evaporate and condenses in surface of plastic products to form metallic film;
E, topcoating: surface of plastic products spray paint D step being coated with metallic film, hand spray or automatic spraying operating can be used during spray base, attentional manipulation finish paint film thickness 5 ~ 10 μm, finish paint requires transparent and has good water tolerance, wear resistance, weathering resistance; Finish paint can select any one of acrylate varnish, polyester varnish or polyurethane lacquer;
F, baking finish paint: plastics E step being sprayed with finish paint carry out drying treatment, make finish paint complete drying, so far, all terminate in the operation of surface of plastic products metal-coated films.
