Abstract

The invention discloses a plastic surface processing process, which includes the following steps: a. semi-finished product processing: screening plastic particles for twice warming processing, and leading the plastic particles to be formed in blister mode to generate a semi-finished product; b. spraying: performing spraying on a metal coating layer of the semi-finished product; c metal plating: cleaning the surface of the semi-finished product, removing impurities and plating metal on the surface of the semi-finished product; and d. lettering: lettering on the semi-finished product through a mold to generate a finished product. Through the mode, the plastic surface processing process can be used for manufacturing plastic products which are used for goods containers and packing materials and have the function of environment protection.

Description

Technique for treating plastic surface
Technical field
The present invention relates to field of plastics processing, particularly relate to a kind of technique for treating plastic surface.
Background technology
Current plastic material has been used to produce diversified product, and Different products is also different to the requirement of plastic raw materials.Polyester is a kind of engineering plastics of function admirable, and just very popular since coming out, output increases year by year, and range of application also constantly enlarges.According to estimates, world's production of polyester ability is about 1200kt/a at present, and wherein major part is used for spinning, has only the raw materials for production of sub-fraction as polyester bottles and packaging film.In recent years, the Application and Development of non-polyester receives the attention of countries in the world gradually, especially developed country apparently higher than fiber-grade polyester, the growth rate of production capacity and output is also obviously greater than fiber-grade polyester to the input of non-polyester.Polyester bottles is occupied critical role in social life as the main application of non-polyester, and bottle-grade polyester chip is divided into two types of copolymerization, homopolymerizations, can be divided into according to different purposes and be used for mineral water bottle, carbonated drink bottle, other food containers and packaging material.Domestic bottle level polyester has very big development space, therefore is necessary to accelerate the exploitation of new product and the construction of new projects, to adapt to the demand that polyester packaging material market develops rapidly.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of technique for treating plastic surface, can make the plastic product with environmental-protection function that is used for article container and packaging material.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of technique for treating plastic surface is provided, may further comprise the steps: a. processes semi-finished product: the screening plastic pellet, carry out the processing of heating for twice; With the plastic pellet plastics sucking moulding, generate semi-finished product; B. spray paint: on half-finished coat of metal, spray paint; C. plating: surface of semi-finished is cleaned, remove impurity, in the surface of semi-finished metal plated; D. carve characters: through mould semi-finished product are carved characters, generate finished product.
In preferred embodiment of the present invention; Plastic pellet carries out heating the first time to liquid condition among the said step a, extrudes the liquid after heating for the first time, liquid is prolonged to press be semi-finished product; The semi-finished product that form are carried out heating the second time, then with the semi-finished product plastics sucking moulding after heating for the second time.
In preferred embodiment of the present invention, be coated with a prime coat in surface of semi-finished among the said step b, form a vacuum coating on prime coat surface, spray a transparent middle enamelled coating at the vacuum coating laminar surface, at last at the transparent top coat layer of middle enamelled coating surface spraying one.
In preferred embodiment of the present invention, said step c plating adopts any one in chemical plating process and the sputtering process.
The invention has the beneficial effects as follows: technique for treating plastic surface of the present invention can be made the plastic product with environmental-protection function that is used for article container and packaging material.
The specific embodiment
Set forth in detail in the face of preferred embodiment of the present invention down, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
A kind of technique for treating plastic surface may further comprise the steps:
A. process semi-finished product: the screening plastic pellet; Carry out the processing of heating for twice, plastic pellet carries out heating the first time to liquid condition, extrudes the liquid after heating for the first time; Liquid is prolonged pressure be semi-finished product; The semi-finished product that form are carried out heating the second time, with the semi-finished product plastics sucking moulding after heating for the second time, generate semi-finished product then;
B. spray paint: on half-finished coat of metal, spray paint; Be coated with a prime coat in surface of semi-finished; Form a vacuum coating on prime coat surface, spray a transparent middle enamelled coating, at last at the transparent top coat layer of middle enamelled coating surface spraying one at the vacuum coating laminar surface;
C. plating: surface of semi-finished is cleaned, remove impurity, in the surface of semi-finished metal plated, plating adopts any one in chemical plating process and the sputtering process;
D. carve characters: through mould semi-finished product are carved characters, generate finished product.
Be different from prior art, technique for treating plastic surface of the present invention can be made the plastic product with environmental-protection function that is used for article container and packaging material.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
