Abstract
The invention discloses an antistatic rubber plate. The antistatic rubber plate is characterized by being mainly prepared from the following raw materials in parts by weight: 70-80 parts of regenerated rubber, 50-70 parts of titanium concentrate powder, 1-3 parts of zinc oxide, 1-2 parts of sulfur, 1-2 parts of stearic acid, 1-2 parts of an accelerant, 1.5-2.5 parts of an anti-aging agent and 3-5 parts of pine tar. The invention also provides a preparation method of the antistatic rubber plate. The antistatic rubber plate disclosed by the invention does not adopt graphite, the conductive function of the titanium concentrate powder in the antistatic rubber plate is established, and the regenerated rubber is adopted as a raw material on the premise that the quality of the antistatic rubber plate is ensured, so that the production and manufacturing cost is greatly reduced and pollution can be reduced; the cost is greatly reduced and the yield is greatly improved.
Description
Technical field
The present invention relates to a kind of rubber plate and preparation method thereof, particularly a kind of Antistatic rubber plate and preparation method thereof.
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, makes production cost higher.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, and provide a kind of Antistatic rubber plate, not graphitiferous, starting material are easy to get, and under the prerequisite of quality ensureing Antistatic rubber plate, considerably reduces manufacturing cost, decreasing pollution.Present invention also offers the preparation method of this kind of Antistatic rubber plate.
Technical scheme of the present invention is as follows: a kind of Antistatic rubber plate, is characterized in that: the following starting material primarily of parts by weight obtain: regenerated rubber 70-80 part, ilmenite concentrate powder 50-70 part, zinc oxide 1-3 part, sulphur 1-2 part, stearic acid 1-2 part, promotor 1-2 part, anti-aging agent 1.5-2.5 part, Stockholm tar 3-5 part.
Adopt technique scheme, ilmenite concentrate powder is added wherein (ilmenite concentrate powder 1000 yuan/about T), and use regenerated rubber, after wherein adding ilmenite concentrate powder, charge-conduction can be walked by Antistatic rubber plate, thus make Antistatic rubber plate have anlistatig effect.Under the prerequisite ensureing Antistatic rubber plate quality, adopt regenerated rubber as raw material, greatly can reduce manufacturing cost on the one hand, can pollution be reduced on the one hand in addition.The Antistatic rubber plate made, through repeated detection, tensile strength is: 4.5-8MPa, extend 400%-560%, hardness 60-70 Shao Er A, tension set 15-20, proportion 1.5g/cm3, resistance <400 Ω, all technical all reaches the requirement of Antistatic rubber plate national standard; If wherein add other metal essence, then the tensile strength of rubber plate is weak, and frangibility, the requirement of national standard to all technical of Antistatic rubber plate can not be met.
As preferably: the following starting material primarily of parts by weight obtain: regenerated rubber 75-78 part, ilmenite concentrate powder 55-65 part, zinc oxide 1.5-2.5 part, sulphur 1.5-1.8 part, stearic acid 1.5-1.8 part, promotor 1.5-1.8 part, anti-aging agent 1.8-2.0 part, Stockholm tar 4-4.5 part.
As preferably: described starting material also comprise the natural rubber that parts by weight are 20-30 part.
As preferably: the parts by weight sum of described natural rubber and regenerated rubber is 100 parts.
As preferably: described natural rubber is GB 1# or 2# natural rubber.
As preferably: the grade of described ilmenite concentrate powder is more than 60%, more than fineness 300 order, preferred 300-500 order.
Another object of the present invention is achieved in that a kind of preparation method of Antistatic rubber plate, is mixed by the starting material in claim 1 or 2, carries out banburying, opens refining, calendering, sulfuration obtain Antistatic rubber plate.
In technique scheme: described starting material also comprise the natural rubber that parts by weight are 20-30 part.
The preparation method of Antistatic rubber plate of the present invention, wherein do not adopt graphite, establish the electric action that ilmenite concentrate powder plays in Antistatic rubber plate, under the prerequisite ensureing Antistatic rubber plate quality, adopt regenerated rubber as raw material, greatly can reduce manufacturing cost on the one hand, can pollution be reduced on the one hand in addition.
Beneficial effect: compared with prior art, the present invention has following effect: Antistatic rubber plate of the present invention does not adopt graphite, establish the electric action that ilmenite concentrate powder plays in Antistatic rubber plate, under the prerequisite ensureing Antistatic rubber plate quality, adopt regenerated rubber as raw material, greatly can reduce manufacturing cost on the one hand, can pollution be reduced on the one hand in addition; Reduce greatly cost and improve output.From facts have proved that producing Antistatic rubber plate per ton can save electricity 80 degree, 50 kilograms, coal, shorten about 40 minutes production time, comprehensive economic index saves 600 yuan/T.The Antistatic rubber plate manufacturing enterprise of a scale 2000T/, every year cost-saving 1,200,000 yuan of energy, and production capacity about 5% can be improved.
