Problems solved by technology

With the development of my country's rubber industry in recent years, more and more fluorine compounded rubber with special physical properties are used in domestic high-tech products. However, in the existing technology, in order to solve the problems of poor fluidity and difficult molding of fluorine compounded rubber, Even if the formula is adjusted, it is difficult to achieve the excellent physical properties of high strength and high elongation at the same time, and the problem of scorch safety must also be taken into account

Embodiment 1

[0021] The preparation of embodiment 1 fluorine rubber compound rubber

[0022] Table 1 shows the formula and physical properties of the fluororubber compound with high strength and high elongation.

[0023] Table 1 Fluorine rubber compound formula and its physical properties (content in parts by weight)

[0024]

[0025] Oil seals, gaskets, and extrusion in Table 1 mainly refer to the use of fluorine compound rubber. The auxiliary vulcanizing agent L is added to the compound rubber formula to prepare oil seals, gaskets and extruded fluorine compound rubber. The obtained fluorine compound rubber The physical properties are generally higher than that of the blank compound rubber, and the products made of it can eliminate the problems of edge material shortage and demoulding tearing. When used in extruded products, due to the improved fluidity, the extrusion will be smoother. In addition, the extension of T10 time ensures that there will be no scorching during extrusion.

Abstract

The invention provides a fluororubber rubber compound and a preparation method thereof. The fluororubber rubber compound is prepared by mixing binary intermediate-low monney sectional fluororubber rubber, reinforcing system (MT N990 carbon black and inorganic filler), acid absorbing system (active magnesium oxide and superfine calcium hydroxide), vulcanizing system (benzyl triphenyl phosphorus chloride and bisphenol AF), releasing agent (alfux and/or carnauba wax), and multifunctional bisphenol vulcanizing composite assistant vulcanizing agent L; the obtained fluororubber rubber compound has high stretching strength, and high extending rate, increases the scorching time by improving the liquidity of the rubber, therefore, high adaptability of the rubber to different manufacture technical environments and the vulcanizing environments can be ensured, the safety in vulcanizing can be improved, and as a result, the rejection rate of the products can be reduced. The fluororubber rubber compound provided by the invention is applicable to industries such as aerospace, aviation, car, metallurgy, petrochemical industry and electron and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a fluorine rubber compound. Background technique [0002] Fluororubber (fluororubber) refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. Compared with other rubbers, fluororubber has excellent high temperature resistance, oil resistance and resistance to various chemicals. The characteristics of chemical corrosion, so it is widely used in aviation, missiles, petroleum, machinery, rockets, space and other industries. With the development of my country's rubber industry in recent years, more and more fluorine compounded rubber with special physical properties are used in domestic high-tech products. However, in the existing technology, in order to solve the problems of poor fluidity and difficult molding of fluorine compounded rubber, Even if the formula is adjusted, it is difficult to achieve the excel...
