Problems solved by technology

[0004] However, in the prior art, electroplating is generally used for coating the surface of polymer material products. Electroplating has high requirements on the conductivity of materials, and general polymer materials are insulating, so polymer materials need to be coated. The material is modified a lot and conductive particles are implanted, otherwise the film-forming performance after electroplating is poor, the gloss and appearance are not good, and the traditional electroplating method pollutes the environment seriously, which does not conform to the theme of green environmental protection in today's society

Embodiment 1

[0027] The selected polymer material product is ABS polymer plastic shower head, and the specific treatment process is: (1) Clean the surface of the shower head through an ultrasonic cleaning device; (2) Epoxy resin that will be diluted by monomer polymer The polymer is covered on the surface of the cleaned shower head by spraying and immersion treatment, so as to form a 1-10 micron epoxy resin polymer primer layer on the surface of the shower head, so that the irregular or rough surface shower head can be modified into The surface is smooth and flat, and then heated by ultraviolet radiation to cure the epoxy resin polymer primer layer to form a solid-state hardened surface layer to be coated; (3) Send the above-mentioned cured products into the equipment equipped with coating components and ion sources In the vacuum chamber, vacuumize and preheat to 100 degrees. When the vacuum degree reaches 7*10e-3, enter 0.1Pa argon gas, turn on the ion source to activate and modify the sur...

Embodiment 2

[0029] The selected polymer material product is also ABS polymer plastic shower head. The specific treatment process is: (1) Clean the surface of the shower head by ultrasonic cleaning device; (2) Polyurethane resin that will be diluted by monomer polymer The polymer is covered on the surface of the cleaned shower head by spraying and immersion treatment, so as to form a 1-10 micron polyurethane resin polymer primer layer on the shower head surface, which can modify the irregular or rough surface of the shower head to the surface Clean and flat surface, and then heated by ultraviolet radiation to cure the polyurethane resin polymer primer layer to form a solid hardened surface layer to be coated; (3) send the above cured products into a vacuum equipped with coating components and ion sources In the room, vacuumize and preheat to 150 degrees. When the vacuum degree reaches 7*10e-3, introduce 0.5Pa argon gas, and turn on the ion source to activate and modify the surface of the pr...

Embodiment 3

[0031] The selected polymer material product is also ABS polymer plastic shower head. The specific treatment process is: (1) Clean the surface of the shower head by ultrasonic cleaning device; (2) Polyurethane resin that will be diluted by monomer polymer The polymer is covered on the surface of the cleaned shower head by spraying and immersion treatment, so as to form a 1-10 micron polyurethane resin polymer primer layer on the shower head surface, which can modify the irregular or rough surface of the shower head to the surface Clean and flat surface, and then heated by ultraviolet radiation to cure the polyurethane resin polymer primer layer to form a solid hardened surface layer to be coated; (3) send the above cured products into a vacuum equipped with coating components and ion sources In the room, vacuumize and preheat to 200 degrees. When the vacuum degree reaches 7*10e-3, introduce 2Pa nitrogen gas, and turn on the ion source to activate and modify the surface of the p...

Abstract

The invention discloses a surface plating technique for a polymer material product. The technique comprises the following steps that (1) the product is washed; (2) an organic polymer base layer is arranged on the surface of the product; (3) the product is sent into a vacuum chamber provided with a plating assembly and an ion source, vacuumizing is conducted, preheating is conducted till the temperature reaches 100-200 DEG C, argon at the pressure of 0.1-2 Pa or nitrogen at the pressure of 0.1-2 Pa is introduced till the vacuum degree reaches 7*10e-3, and the ion source is turned on for activating and modifying the surface of the product; (4) the ion source is turned off, and a metallic luster layer is plated on the surface of the product; (5) the product is taken out after plating is finished; and (6) finally the surface of the product is further covered with a surface coloring cover layer. According to the surface plating technique for the polymer material product, by the adoption of the working procedures, the product added value can be increased through plating, and environmental friendliness is also achieved.

Description

technical field [0001] The invention belongs to the field of material science, and specifically refers to a surface coating process of a polymer material product. Background technique [0002] At present, a large number of electromechanical products and their supporting materials are made of polymers. Polymer materials have unique structures, easy modification, and easy processing, which make them have incomparable and irreplaceable excellent properties of other materials. Therefore, it is widely used in various fields such as science and technology, national defense construction and national economy, and has become an indispensable material in all aspects of basic necessities of life in modern society. Polymer materials are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives, and polymer-based composite materials. [0003] Polymer material surface coating technology can give polymer material produc...
