A kind of environment-friendly and corrosion-resistant epichlorohydrin rubber

Abstract

The invention relates to the field of rubber, particularly an environment-friendly corrosion-resistant epichlorohydrin rubber which is composed of the following components in parts by weight: 50-80 parts of epichlorohydrin rubber, 10-15 parts of silicon dioxide, 20-30 parts of quick-extrusion carbon black, 1-5 parts of anti-aging agent, 0-5 parts of antiozonant, 0.5-1.5 parts of vulcanizing agent, 0.5-1.5 parts of stearic acid, 2-5 parts of magnesium oxide and 1-3 parts of calcium carbonate. By using microcrystalline wax, which has the advantages of high melting point, low migration rate and small and uniform crystals, as the anti-aging agent, the film formed by the wax, which has the advantages of high binding firmness with rubber, favorable flexibility and favorable shielding property, can have an anti-aging action, and can also generate an isolating layer on the rubber surface to perform the demolding function and reduce the contact between the epichlorohydrin rubber and the metal mold, thereby decelerating the metal corrosion and resisting metal corrosion without adding any other component; and the lead-free vulcanizing agent PDM conforms to the requirement for environment friendliness.

Description

technical field [0001] The invention relates to the field of rubber, in particular to an environment-friendly and corrosion-resistant chloroether rubber. Background technique [0002] Chlorine ether rubber is a saturated rubber whose main chain is composed of C-O and C-C, and its side chain contains chlorine atoms. The main chain has an ether structure. Due to the presence of oxygen atoms, the molecule is easy to rotate. Polar groups or unsaturated bonds. This structural feature determines that polyether rubber has the characteristics of ozone resistance, weather resistance, chemical resistance, cold resistance and good processing performance. [0003] Due to its above-mentioned characteristics, chloroether rubber is mainly used in the manufacture of freon refrigerant seals and rubber hoses; various oil seals, transformer diaphragms, sound-absorbing and shock-absorbing materials, oil tank linings of construction machinery; oil well production equipment seals, oil well high ...
