Problems solved by technology

[0002] In the process of modern rubber processing, airtightness enhancers are mainly used for innerliner rubber to improve the airtightness of rubber products such as tires; currently, most tire companies use brominated butyl rubber (BIIR) and chlorobutyl Rubber (CIIR) produces innerliner rubber. In order to reduce costs, methods such as increasing the amount of styrene-butadiene rubber (SBR) in the rubber compound, adding butyl rubber (IIR) reclaimed rubber and calcium carbonate to reduce the rubber content, etc., but the rubber compound Performance is not ideal

Abstract

The invention relates to an airtightness enhancer and its preparation method and application. The airtightness enhancer comprises the following ingredients in parts by weight: 40-80 parts of component A, 10-30 parts of component B, and 10-20 parts of component C , component D5‑10 parts; component A is petroleum pitch; component B is calcium stearate, fly ash, talcum powder, light calcium carbonate, vermiculite, kaolin, clay, mica powder, montmorillonite Component C is a mixture of one or more of pentaerythritol stearate, glyceryl monostearate, fatty acid alkanolamide, hydrogenated oil; component D is fatty alcohol poly One or two or more of oxyethylene ether, Span, and Tween are mixed. The airtightness enhancer of the invention can promote the mixing between rubbers, improve the uniformity of the mixed rubber, and increase the airtightness of the airtight layer.

Description

technical field [0001] The invention relates to an air tightness enhancer and its preparation method and application, belonging to the technical field of fine chemicals. Background technique [0002] In the process of modern rubber processing, airtightness enhancers are mainly used for innerliner rubber to improve the airtightness of rubber products such as tires; currently, most tire companies use brominated butyl rubber (BIIR) and chlorobutyl Rubber (CIIR) produces innerliner rubber. In order to reduce costs, methods such as increasing the amount of styrene-butadiene rubber (SBR) in the rubber compound, adding butyl rubber (IIR) reclaimed rubber and calcium carbonate to reduce the rubber content, etc., but the rubber compound The performance is not ideal. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides an airtightness enhancer and its preparation method and application. [0004] Technical scheme of the present inve...
