Abstract

The invention discloses a heat-resisting ternary fluorine rubber non-metallic compensator. The heat-resisting ternary fluorine rubber non-metallic compensator is made of, by weight, a proper quantity of ternary fluorine rubber, 100-110 parts of non-alkali bulk yarn glass fiber fabric, 50-55 parts of vinylidene fluoride-hexafluoropropylene copolymer, 200-220 parts of acetone, 2-2.5 parts of benzyl triethyl ammonium chloride, 80-85 parts of a potassium hydroxide water solution with the concentration being 5-5.5 wt%, 110-120 parts of a hydrogen peroxide water solution with the concentration being 30-31 wt%, a proper amount of a hydrochloric acid water solution with the concentration being 36-38 wt%, 3-3.5 parts of zinc oxide crystal whiskers, 8-9 parts of organic montmorillonite, 1-1.3 parts of dimethyl dihydrogenated tallow ammonium chloride and 1.6-1.8 parts of tetrabutyl titanate. The dimethyl dihydrogenated tallow ammonium chloride and the tetrabutyl titanate are utilized to modify the organic montmorillonite, heat resistance and reaction activity of the montmorillonite are improved, crosslinking density is improved, and the heat aging property of a material is improved.

Description

technical field [0001] The invention relates to the technical field of non-metallic compensators, in particular to a heat-resistant ternary fluororubber 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 temp...
