Abstract

The invention relates to a synthetic rubber seal ring material and a preparation method thereof. The synthetic rubber seal ring material is mainly prepared from components in parts by weight as follows: 10-100 parts of fluorelastomer, 10-100 parts of 3F fluorelastomer, 0.1-100 parts of bisphenol AF, 0.1-5 parts of a vulcanizing agent, 0.1-5 parts of an accelerant BPP, 3-130 parts of inorganic filler, 1-100 parts of calcined diatomite, 1-30 parts of tetrafluoro micropowder, 0.1-5 parts of a polymer processing aid, 0.1-5 parts of American palm wax, 1.1-50 parts of a rubber pigment coloring agentand 0.1-10 parts of fluororubber polymers. The preparation method comprises steps as follows: components are weighted in proportion; fluorelastomer, 3F fluorelastomer and fluororubber polymers are premixed; the mixture and the remaining components are added to an internal mixer for mixing, the mixture is left to stand for hours, the internal mixer is opened to discharge sheets; heating and vulcanization molding are performed, still standing is performed for hours after molding, and a product is obtained. The synthetic rubber seal ring material has high chemical inertness, good stability, superhigh wear resistance, acid-base resistance and corrosion resistance, tear resistance and the like; the synthetic rubber seal ring material can resist the temperature of 220 DEG C, which is far higherthan that of ordinary rubber seal rings; the average service life is 4 times or longer that of the ordinary rubber seal rings.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a synthetic rubber sealing ring material and its preparation and application. Background technique [0002] Rubber material is a polymer material that can quickly recover from deformation under large deformation. It is one of the important basic industries of the national economy. It provides light industrial rubber products for daily use and medical use that are indispensable in people's daily life; for mining , Transportation, construction, machinery, electronics and other heavy industries and emerging industries provide a variety of rubber production equipment or rubber parts, which are widely used. In recent years, the rapid development of the rubber industry has put forward higher requirements for rubber products. However, the current common rubber sealing ring products have a short lifespan when used in the printing and dyeing industry. From a commercial point of...
