Anti-wear electrical ternary fluororubber nonmetal compensator and preparation method thereof

Abstract

The invention discloses a wear-resistant electrical ternary fluororubber nonmetal compensator, which is prepared from the following raw materials in parts by weight: a proper amount of ternary fluorubber, 100-110 of alkali-free bulked yarn fiberglass fabric, 50-55 of vinylidene fluoride-hexafluoropropylene copolymer, 200-220 of acetone, 2-2.5 of TEBA, 80-85 of 5-5.5 wt% potassium hydroxide aqueous solution, 110-120 of 30-31 wt% hydrogen peroxide aqueous solution, a proper amount of 36-38 wt% hydrochloric acid aqueous solution, 3-3.5 of zinc oxide crystal whiskers, 0.5-0.7 of zirconium oxychloride, 2.5-3 of PPS micron powder, and 0.3-0.5 of trifluoroethyl acrylate. According to the technical scheme of the invention, the compatibility and the heat resistance of PPS micron powder and rubber are improved. Meanwhile, the PPS micron powder can improve the toughness and the wear resistance of the rubber. Therefore, the toughness and the wear resistance of the compensator are improved.

Description

technical field [0001] The invention relates to the technical field of non-metallic compensators, in particular to an anti-friction ternary fluorine rubber non-metallic compensator and a preparation method thereof. Background technique [0002] Non-metallic compensators are also called fabric compensators, non-metallic expansion joints or non-metallic soft connections. Corrosion, wear resistance, small mass, low cost, convenient installation and maintenance, etc. As a flexible connecting element, non-metallic compensators are widely used in fluid conveying pipelines and equipment in mining, metallurgy, electric power, cement, building materials, nuclear energy, petrochemical and other industries. [0003] In recent years, the material, structure, production process and application fields of non-metallic compensators in my country have been developing continuously. Now the applicable medium of the non-metallic compensator has developed from the initial flue gas in the low t...

Problems solved by technology

[0004] The adhesion between rubber and glass fiber is poor. Although the article "Research and Development of Ternary Fluorine Rubber Non-metallic Compensator" uses silane coupling agent to treat the surface of glass fiber, it can be used in high temperature, high pressure, highly corrosive gas, liquid and solid mixed media. Among them, the silane coupling agent is easy to decompose, which makes the glass fiber and rubber separate, reduces the strength of the material, causes leakage, shortens the service life, needs to be improved, and also needs to improve the wear resistance of the non-metallic compensator
