Pushing-disk clutch rubber gas bag and production method thereof

Abstract

The invention discloses a pushing-disk clutch rubber gas bag. The pushing-disk clutch rubber gas bag comprises the following raw materials of, in parts by weight, 50-70 parts of natural rubber, 30-50parts of nitrile rubber, 1-2 parts of stearic acid, 1.5-2.5 parts of anti-aging agent A, 0.6-1.0 part of paraffin, 8-12 parts of carbon black N330, 12-18 parts of carbon black N774, 1.0-2.5 parts of graphene, 12-18 parts of zinc oxide, 0.8-1.2 parts of pine tar, 0.4-0.6 part of accelerator M, 0.6-1.0 part of accelerator CZ and 2.0-2.5 parts of sulfur. The production method comprises the six technology steps of rubber mixing, rolling and cutting, extrusion, molding, vulcanization and packaging, and during vulcanization production, vulcanization temperature, time and pressure are adjusted, so that the problem that manual production requires much time and energy is solved fundamentally; and due to the fact that liquid water is low in cost and can be recycled, the production cost of an enterprise can be obviously reduced.

Description

[0001] 1. Technical field:

[0002] The invention relates to a production process of rubber products, in particular to a push disc 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. Push plate clutch rubber airbags are commonly used in the market at present. The production process includes six processes including rubber mixing, calendering and cutting, extrusion, molding, vulcanization, and packaging. The vulcanization process is...
