Problems solved by technology

[0002] Although the existing fluorine rubber has the characteristics of high temperature resistance, chemical corrosion resistance, oil resistance, and aging resistance, its processing performance is poor, and it is prone to tearing and fracture during production and processing, which seriously affects the scope of use; low temperature resistance is poor
Moreover, the rate of defective products produced in the production process is high, resulting in increased processing costs and high prices.

Embodiment 1

[0010] A kind of fluorine rubber described in the present embodiment, it comprises fluorine rubber 2602, acid absorbing agent, spray carbon black, vulcanizer, vulcanization auxiliary agent, release agent and STR tear-resistant resin, wherein the mass parts of each component is : 100 parts of fluorine rubber 2602, 3 parts of acid absorbing agent, 10 parts of spray carbon black, 2 parts of vulcanizing agent, 1 part of vulcanization aid, 2.5 parts of release agent, 2 parts of STR tear-resistant resin.

[0011] A preparation method of fluororubber. First, weigh each component according to the formula amount, roll the fluororubber 2602 on the open mill, and then add the release agent and spray carbon black evenly, and then add the powder after eating up the powder Mix the acid absorbing agent and STR tear-resistant resin evenly, and finally add the vulcanizing agent and vulcanizing aid, mix well and then park for 8 hours before vulcanizing. During the rubber mixing, the temperature ...

Abstract

The invention relates to the field of rubber, in particular to fluororubber which comprises the following components by mass: 100 parts of fluororubber 2602, 3 parts of an acid-acceptor, 10 parts of spraying carbon black, 2 parts of a vulcanizing machine, 1 part of a vulcanizing agent, 2.5 parts of a release agent and 2 parts of STR anti-tear resin. According to the fluororubber and a preparation method thereof, the acid-acceptor is added in the formula to remove acidic materials inside all raw materials, and besides, the STR anti-tear resin is added to improve the anti-tear capability of the fluororubber; in the preparation process of the fluororubber, secondary vulcanizing is adopted to improve the mechanical property and the compression set of the fluororubber.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a fluorine rubber and a preparation method thereof. Background technique [0002] Although the existing fluorine rubber has the characteristics of high temperature resistance, chemical corrosion resistance, oil resistance, and aging resistance, its processing performance is poor, and it is prone to tearing and fracture during production and processing, which seriously affects the scope of use; low temperature resistance is poor . Moreover, the rate of defective products produced in the production process is high, resulting in increased processing costs and high prices. Contents of the invention [0003] The object of the present invention is to provide a fluororubber with reasonable formula, simple process, strong mechanical properties and a preparation method thereof in order to solve the above technical deficiencies. [0004] In order to achieve the above object, a kind of fluorine ru...
