Embodiment 1

[0023]The heat-resistant and corrosion-resistant screen is made by extruding through a rotating head. The specific extrusion molding process includes the following steps: the first step, the weight ratio of acrylate rubber to chlorinated polyether is 51~56:82~ 93, and based on the total weight of 100 parts by weight of acrylate rubber and chlorinated polyether, the total amount of reinforcing fillers is 20 parts by weight, the total amount of antioxidants is 0.5 parts by weight, and the total amount of plasticizers 8 parts by weight, the acrylic rubber is masticated, and then a reinforcing filler, an anti-aging agent and a plasticizer are added for mixing to obtain an acrylic rubber masterbatch. The masticating time is 15 minutes, and the mixing time is 35 minutes; Two steps, the acrylic ester rubber masterbatch that step one obtains is dispersed in ionic liquid and isobornyl methacrylate to form acrylic ester rubber compound glue, with the total weight of the acrylic ester rub...

Abstract

The invention relates to the technical field of screen production, in particular to an extrusion molding process method of a heat-resistant corrosion-resistant screen. Raw material source is wide, preparation method is simple and convenient, chlorinated polyether and acrylate rubber are blended, co-crosslinked and synergistically matched; the prepared screen can be widely applied to screening machines in the industries of metallurgy, mines, coal, building materials, water conservancy, road construction and the like, and is a substitute product of a steel plate punched screen, a steel wire meshgrid, a stainless steel screen plate and a rubber screen plate. The product has the advantages of light weight, high screening efficiency, no hole blockage, friction resistance, impact resistance, tear resistance, long service life, low noise, convenience in installation, high comprehensive benefits and the like.

Description

technical field [0001] The invention belongs to the technical field of screen production, and in particular relates to an extrusion molding process for a heat-resistant and corrosion-resistant screen. Background technique [0002] With the development of the polymer material industry, new materials are provided for the manufacture of high-quality and high-efficiency screen materials. At present, the screen materials used at home and abroad include elastic plastic, stainless steel, nylon and other materials. The rubber screen surface can be directly made of rubber, and its screen holes are square, round or slotted. The screen surface made of polyurethane has the advantages of good wear resistance, low noise, open-air storage and rubber saving. Nylon sieves have been used instead of stainless steel sieves to manufacture slotted sieve surfaces. The disadvantage is that the length of the sieves is limited, generally 60mm, and can only be combined into small sieve plates. At p...
