Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with specific embodiments, but it should not be understood that the scope of the above subject of the present invention is limited to the following examples.

[0043] Examples 1-6 are rubber compounds prepared by using different proportions of components in the bisphenol vulcanization system. Table 1 shows the specific composition and the formula composition and tear performance of the examples with different component contents.

[0044] The preparation method of Examples 1-6 is as follows: firstly weigh binary or ternary fluororubber raw rubber and auxiliary agents in the formulation according to the ratio of parts by weight, and the auxiliary agents are bisphenol AF, benzyl triphenyl chloride Phosphorus, magnesium oxide, calcium hydroxide, carbon nanotubes, release agent WS280, carnauba wax, carbon black, and mix the additives evenly. Then the fluororubber raw rubber is masticated in the in...

Abstract

The invention provides a tear-resistant fluoro-rubber mixed compound and a preparation method thereof, which belong to the filed of mixed compound application. The tear-resistant fluoro-rubber mixed compound is formed by mixing a binary fluoro-rubber, a ternary fluoro-rubber, active magnesium oxide, calcium hydroxide, a vulcanization system (bisphenol vulcanization system: bisphenol AF, benzyl triphenyl phosphorus chloride or peroxide vulcanization system: DBPH, TAIC), a carbon nanotube, a releasing agent, a reinforcing agent, and the like. The mixed compound prepared according to the invention is good in tear resistance, and can be widely used in rubber products.

Description

technical field [0001] The invention relates to a tear-resistant fluororubber compound and a preparation method, belonging to the field of material engineering and technology. Background technique [0002] Fluorine rubber refers to a polymer elastomer that contains fluorine atoms on the carbon atoms of the main chain or side chain. Because the polymer chain contains fluorine atoms, it has better high temperature resistance, oil resistance, various chemical medium resistance, weather resistance, electrical insulation performance, radiation resistance and good physical and mechanical properties than ordinary rubber. Performance, etc., widely used in aviation, aerospace, shipbuilding, automobiles, petroleum, machinery, metallurgy, chemical industry and other fields. Although fluororubber has excellent properties compared with other rubbers, it also has shortcomings, such as poor low temperature performance, poor fluidity, easy compression deformation, raw rubber processing per...
