Surface Hardening Technology of Polymer Synthetic Materials

Abstract

The invention provides a high molecular synthetic material surface hardening technology. The high molecular synthetic material surface hardening technology is characterized by comprising the steps that 1, synthetic material surface pretreatment, wherein a UV coating is sprayed to a hardening surfaces of materials by using a UV spraying line, and hardening is conducted through ultraviolet irradiation; 2, ion surface treatment, wherein ionic materials are fixed to a fixture and then put into vacuum cleaning equipment, ionic equipment is used for generating discharging ions, and ionic bombardment is conducted on the UV coating; and surface cleaning is conducted to remove stress between the materials with different properties; 3, optical dielectric thin film hardening, wherein heating is conducted on optical dielectric materials by high-power electron beams generated by an electronic gun in a vacuum environment, and the materials are melted and evaporated to be attached to the surface of the materials to form thin films; 4, stress relieving, wherein bombardment treatment is conducted on dielectric films by using ion source equipment for one minute; and 5, surface anti-fouling protection layer manufacturing, wherein a layer of anti-fouling material is formed on the surface of the materials through evaporation by using resistant heating and prevention evaporating in vacuum. By means of the high molecular synthetic material surface hardening technology, the surface hardness of the high molecular synthetic material can be greatly improved.

Description

technical field [0001] The invention relates to the field of vacuum films (such as touch panel, optical lens, home appliance panel, trademark logo, car logo decoration, glasses, etc.), in particular to a surface hardening process of a polymer synthetic material (commonly known as plastic or resin). Background technique [0002] Polymer synthetic material (commonly known as plastic or resin), has good chemical stability, no rust, good insulation, low thermal conductivity, easy molding, good coloring, and easy processing. Therefore, it is widely used in the production of various products in life, but due to its own material problems, its surface hardness is poor and prone to scratches, such as the usual PC / PMMA surface hardness <2H (500g) (a hardness test method , use the pencil of Mitsubishi 2H in Japan, with a vertical load of 500g, and the pencil is tilted at 45 degrees and scratched at a constant speed on the surface of the material to observe whether there are scratche...

Problems solved by technology

Therefore, it is widely used in the production of various products in life, but due to its own material problems, its surface hardness is poor and prone to scratches, such as the usual PC / PMMA surface hardness <2H (500g) (a hardness test method , use the pencil of Mitsubishi 2H in Japan, with a vertical load of 500g, the pencil is inclined at 45 degrees and scratched at a constant speed on the surface of the material, and observe whether there are scratches on the surface

If there is no scratch, judge OK, if there is, it does not meet the standard and judge NG), so the application field is limited

[0003] In a nutshell, the existing surface spraying hardening (UV, PU spraying) has the following disadvantages: 1. The surface hardness improvement effect is limited, the process can only reach 3H (500g), and the application field is limited; 2. The coating is anti- The pollution ability is poor, oil, fingerprints, water, etc. are easy to contaminate the surface of the product, and it is not easy to clean; 3. The friction coefficient of the coating is high, and the surface is not smooth enough. It is not smooth enough for window products. <40 degrees; 4. There will be 1%-3% light loss in the product transmittance after spraying, which will affect the product function
