Abstract
The invention discloses a preparation method of a silica gel sealing medium partition plate, relating to a preparation method of a heat-resistant sealing gasket. The silica gel sealing medium partition plate comprises the following raw material components in parts by weight: 100 parts of dimethyl siloxane and vinyl siloxane polymers, 50 parts of special white carbon black for silicon rubber, 2 parts of zinc oxide, 6 parts of silane, 10 parts of silicon hydride oil, 1 part of DBPMH (2,5-dimethyl-2,5-di (tert-butylperoxy) hexane) and 1.5 parts of boric acid ester and is prepared by copolymerizing, forming and vulcanizing the raw materials in parts by weight per se. The silica gel sealing medium partition plate is formed by copolymerizing dimethyl siloxane and a small amount of vinyl siloxane, wherein the content of vinyl is 0.1%-0.3%, the tensile strength of a finished product reaches 7.2 MPa, the elongation at break reaches 600%, the hardness reaches 61 (A), the breakdown voltage reaches 19 Mv/m, the volume resistance reaches 9.2*1014 omega.cm, the brittleness temperature reaches -65 DEG C, and the using temperature range is -50 DEG C-+250 DEG C.
Description
Technical field
The present invention relates to a kind of preparation method of heat-resistant seal gasket.
Background technology
In the electrolysis of aluminum processing units, the anode rod iron is by a rectangular opening turnover electrolyzer.In the electrolysis of aluminum course of processing, can go out many harmful exhausts respectively.For preventing to damage operator's health, process unit generally is provided with the asbestos lining at the rectangular opening place, to realize the movable sealing between mouthful edge and the rod iron.But the rod iron gangway on anode rod iron and the electrolyzer is difficult to accurate location, asbestos material so frequent the damage, and the wadding of asbestos lining, bits fall into the interior meeting of groove on the one hand influence product quality, on the other hand, after the damage, can cause a large amount of harmful exhausts to enter the operating space, infringement operator's health.
Summary of the invention
The present invention is directed to above problem, a kind of good springiness is provided, the life-span is long, the preparation method of erosion-resisting silica gel sealing median septum.
Technical scheme of the present invention is: its feed composition and weight part thereof are: 1.5 parts of 50 parts of the special-purpose white carbon blacks of dimethyl siloxane and 100 parts of ethene siloxane polymerization bodies, silicon rubber, 2 parts in zinc oxide, 6 parts in silane, 10 parts of hydrogenation silicone oil, two 251 parts, boric acid fat; Above-mentioned raw materials makes through copolymerization, moulding, sulfuration by weight part separately.
It also comprises the tinting material of 1.5 weight parts.
Sulfuration employing 175～185 ℃, 25～32 minutes, pressure are the disposable compression molding of 8～12MPa.
The present invention is formed by dimethyl siloxane and the copolymerization of small amount of ethylene radical siloxane, contents of ethylene is 0.1～0.3%, the tensile strength of finished product reaches that 7.2Mpa, tensile yield reach 600%, hardness reaches 61 (A), voltage breakdown reaches 19Mv/m, volume resistance reaches 9.2 * 1014 Ω .cm, temperature limit of brittleness reaches-65 ℃, use temperature scope-50 ℃～+ 250 ℃.
