Embodiment 1

[0032] Carry out rubber mixing (mechanical blending method) according to the components specified in Table 1 below, and the mixing of rubber materials is carried out in two stages. The first stage of mixing is carried out in the F-type or GK type internal mixer, and the second stage of mixing is carried out in the double-roller open mill. The order of feeding during one-stage mixing is fluororubber, N,N'-m-phenylene bismaleimide, metal oxide, dispersant (if any), filler (if any). The organic peroxide is added during the second-stage mixing. The performance tests of the obtained rubber compounds are carried out, and the test results are listed in Table 2.

Embodiment 2

[0034] Carry out rubber mixing by each component specified in the following table 1, the mixing of rubber material is the same as embodiment 1, has listed test result in table 2.

Embodiment 3

[0036] Carry out rubber mixing by each component specified in the following table 1, the mixing of rubber material is the same as embodiment 1, has listed test result in table 2.

Abstract

The invention discloses a fluororubber / N,N'-m-phenylene bismaleimide composite. The N,N'-m-phenylene bismaleimide composite comprises the following components mainly including, by weight, 100 parts of fluororubber capable of being cross-linked through peroxides, 5-30 parts of N,N'-m-phenylene bismaleimide, 3-5 parts of metallic oxide and 1-3 parts of oxganic peroxides. In the composite material, chemical connection is established between a dispersion phase of N,N'-m-phenylene bismaleimide resin and fluorine rubber molecules serving as matrix, so that the composite material is enabled to be endowed with better high-temperature resistance and medium resistance.

Description

technical field [0001] The invention relates to a fluorine rubber / N,N'-m-phenylene bismaleimide composite material, which belongs to the technical field of polymer materials. Background technique [0002] Fluorine rubber is an important synthetic polymer elastomer. Its main chain or side chain carbon atoms contain extremely electronegative fluorine atoms, which make it have excellent properties incomparable to other rubbers, such as heat resistance, oil resistance, and heat resistance. Chemicals, weather resistance, oxidation resistance and other characteristics, and has good physical and mechanical properties, electrical insulation properties and radiation resistance, etc., widely used in automobiles, oil and gas processing, chemical industry, food processing, electronic appliances, aerospace, wire and cable and other fields . [0003] However, fluorine rubber also has some disadvantages, such as poor processing performance, large drop in mechanical properties at high temp...
