Abstract

The invention discloses a brown fluorubber compound. The brown fluorubber compound is prepared from, by mass, 65 parts to 75 parts of high Mooney viscosity fluorubber, 25 parts to 35 parts of low Mooney viscosity fluorubber, 7 parts to 12 parts of active magnesium oxide, 8 parts to 12 parts of calcium hydroxide, 8 parts to 14 parts of diatomite, 1 part to 4 parts of Brazilian wax, 1 part to 3 parts of brightener, 1 part to 4 parts of fluorine wax, 2 parts to 6 parts of barium sulfate, 15 parts to 20 parts of high-temperature dark brown substances, 15 parts to 20 parts of titanium dioxide, 2 parts to 6 parts of bisphenol, and 1 part to 3 parts of vulcanizing agent in a mixing mode. According to the formula, the raw materials of the brown fluorubber compound are easy to obtain, and the preparing technology is simple. The brown fluorubber compound prepared with the method reaches all index performance of finished fluorubber in the prior art, high tensile strength for breakage is achieved, and the rebound resilience is high. The raw material cost of the brown fluorubber compound is low, machining cost of enterprises is saved, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to a brown fluorine rubber compound and a preparation method thereof, belonging to the technical field of rubber. Background technique [0002] Fluorine rubber is an elastic material with excellent properties. It has good high temperature resistance, radiation resistance, oil resistance, solvent resistance, corrosion resistance, chemical resistance, strong oxidant resistance and good physical properties. It is oil resistant and other harsh working environments. The best glue for lower seals, hoses and gaskets, etc. The processing technology of fluororubber in the prior art is usually complicated, and the color of fluororubber currently on the market is transparent, and its rebound does not meet the standard, which greatly limits its promotion and application. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a brown fluororubber compound and its prepar...
