Abstract
The invention discloses a preparation method of a weatherable and antistatic composite material. The method comprises the following steps: uniformly mixing all components according to certain mass part proportions, adding the obtained mixture into a double screw extruder, carrying out melt blending, extruding, and carrying out cooling granulation to obtain the weatherable and antistatic composite material. The above obtained plastic has the advantages of high notch impact strength, high antistatic performance, high bending strength, high hardness, good weatherability, and difficult cracking, deformation, color fading and other ageing phenomena under high temperature and cold alternate oppression.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of preparation method of Weather-resistant antistatic matrix material.
Technical background
Plastic material is a kind of material of good performance, because plastics have the advantages such as light weight, not corrosion, good insulating, so will use plastics in a lot of links of electronic product production.Plastics are easily processed, finish size stability and surface luster good, easy application.Painted, be widely used in field of electronics.In recent years in electronic apparatus market, plastics keep status in electronic apparatus market, will improve its performance.The generation of such as electrostatic can bring many troubles, as static discharge, can endanger electronics, makes equipment produce various fault, reduction of service life.Along with the market expansion of electric equipment products, more and more higher to the demand of electrostatic-resistant heat conducting plastic, the such as shell of circuit board material, electrical isolation plate, mobile communication equipment.But general-purpose plastics on the market, its thermal conductivity is low, and working temperature is low, and filler hardness is high, large to equipment attrition, easily produces electrostatic.Simultaneously plastics are because in outdoor application, are subject to solar radiation, temperature variation, the impact of the ambient conditionss such as wind and weather, and fading of occurring, variable color, be full of cracks, a series of aging phenomenon such as efflorescence and strength degradation.So modification will be carried out to plastics, to improve its static resistance and weathering resistance, thus meet the requirement of existing market to material property.
