Diaphragm-type clutch rubber air bag and preparation method thereof

Abstract

The invention discloses a diaphragm-type clutch rubber air bag, which comprises the following raw materials (by weight): 85-95 parts of butyl rubber, 5-15 parts of chloroprene rubber, 12-18 parts of zinc oxide, 2-4 parts of stearic acid, 3-5 parts of paraffin, 12-18 parts of carbon black N550, 8-12 parts of carbon black N330, 1.5-2.5 parts of an anti-aging agent D, 0.5-1.5 parts of carbon nanotube, 0.8-1.2 parts of pine tar, 1.5-2.5 parts of an accelerant DM, 1.5-2.5 parts of an accelerant CZ, 1.5-2.5 parts of p-benzoquionone dixoime, and 1.5-2.5 parts of sulphur. The preparation method comprises six processing steps including rubber mixing, calendering and cutting, extrusion, moulding, sulfuration, packaging and the like. During the sulfuration production, sulfuration temperature, time and pressure are adjusted, thus fundamentally solving the problem that manual work is time-consuming and labor-consuming. In addition, liquid water is low-cost and can be recycled, thereby obviously reducing production costs of enterprises.

Description

[0001] 1. Technical field:

[0002] The invention relates to a production process of rubber products, in particular to a diaphragm type clutch rubber air bag and a preparation method thereof.

[0003] 2. Background technology:

[0004] The clutch rubber airbag is a kind of inner membrane of different shapes with good expansion and contraction functions, which is made of rubber as the main material, matched with high-strength fiber cloth, and processed after various processes such as vulcanization. Due to reasons such as raw material ratio, elastic requirements and high thermal conductivity, the current clutch rubber airbags are unsatisfactory in tear resistance, wear resistance, aging resistance and thermal and electrical conductivity. Diaphragm clutch rubber airbags are commonly used in the market at present. Its production process includes six processes including rubber mixing, calendering and cutting, extrusion, molding, vulcanization, and packaging. The vulcanization proces...
