Abstract

The invention discloses a calcium titanate fiber reinforced fluororubber sealing gasket and a production method thereof. The sealing gasket is produced from, by weight, 44-66 parts of fluoro-phosphazene rubber, 26-42 parts of styrene butadiene rubber, 5-8 parts of magnesite, 7-13 parts of coal tar pitch, 3-4 parts of triethylenetetramine, 20-30 parts of hornblende powder, 3-5 parts of 2,2-di(tert-butylperoxy)butane, 10-15 parts of datolite powder, 2-4 parts of lead stearate, 8-14 parts of tall oil modified phenolic resin, 2-3 parts of N,N'-di-n-butylthiourea, 5-10 parts of octyl epoxystearate, 15-20 parts of calcium titanate fibers, 1-2 parts of ethoxyquinoline, 3-5 parts of 2,5-di-t-butylhydroquinone, 2-3 parts of nickel dibutyl dithiocarbamate and 13-15 parts of a modifier. The sealing gasket produced in the invention has the advantages of excellent comprehensive performances, long service life and wide application range.

Description

technical field [0001] The invention relates to a rubber sealing gasket, in particular to a calcium titanate fiber reinforced fluorine rubber sealing gasket and a preparation method thereof. Background technique [0002] Fluorine rubber (fluororubber) refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms endows rubber with excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance, and has been widely used in the field of sealing materials. With the rapid development of science, technology and industry, the performance requirements of fluororubber sealing materials are getting higher and higher. The comprehensive performance of fluororubber gaskets in the existing market is poor, resulting in a short service life and unable to meet the needs of the market. Contents of the invention [0003] The object of the presen...
