According to the preparation method of the antistatic rubber plate, the production raw materials of the antistatic rubber plate comprise the following components in percentage by weight: 70-80% of regenerated rubber, 50-70% of titanium concentrate powder, 1-3% of zinc oxide, 1-2% of sulfur, 1-2% of stearic acid, 1-2% of an accelerant, 1.5-2.5% of an anti-aging agent and 3-5% of pine tar, wherein the antistatic rubber plate is prepared by performing internal mixing, open mixing, calendering and sulfurization on the components, and the grade of the added titanium concentrate powder is more than 60%. According to the preparation method of the antistatic rubber powder, graphite is adopted to establish the conductive function of the titanium concentrated powder in the antistatic rubber plate, and on the premise of ensuring the quality of the antistatic rubber plate, the regenerated rubber is adopted as a raw material, so that on the one hand, the production and manufacturing cost can be greatly reduced, and on the other hand, graphite pollutions can be reduced.
Description
Technical field
The present invention relates to a kind of production technical field for Antistatic rubber plate, particularly by the utilisation technology of ilmenite concentrate powder in antistatic rubber goods.
Background technology
Antistatic rubber plate is widely used in the science and technology field such as electronics, chemical industry, military affairs, space flight, Antistatic rubber plate mainly plays and prevents electrostatic from producing, effectively anti-dry, the effect of anti-static electricity interference, existing production method uses the industrial chemicals such as natural rubber, regenerated rubber, graphite to carry out production Antistatic rubber plate.
For existing production formula and technique, the shortcoming that the black pollution that ubiquity causes because of graphite is large, cost is high, production difficulty is large, in production, natural rubber, regenerated rubber, graphite and industrial chemicals are passed through Banbury mixer banburying, refining is opened in mill, tri-roll press machine rolls, vulcanizing press sulfuration, deburring, cutting is shaping, the process that test package dispatches from the factory.In banburying, open because of graphite light specific gravity in refining process, easily fly upward and cause black dust dirty; Refining time long difficult refining gum forming is opened in another banburying, and graphite price 4000 yuan/about T (ilmenite concentrate powder 1000 yuan/about T), makes production cost higher.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, a kind of preparation method of Antistatic rubber plate is provided, can reach from existing production method and make full use of the starting material that are easy to get, and establish the electric action that ilmenite concentrate powder plays in Antistatic rubber plate, by rubber plate, electric charge is led away, under the prerequisite ensureing Antistatic rubber plate quality, significantly reduce costs, decreasing pollution.
