Ventilated round clutch rubber airbag and preparation method thereof

Abstract

The invention discloses a ventilated round clutch rubber airbag, which comprises the following raw materials in parts by weight: 15-25 parts of cis-butadiene rubber, 35-55 parts of urethane rubber, 15-25 parts of chloroprene rubber, 8-12 parts of zinc oxide, 2-3 parts of stearic acid, 3-5 parts of paraffin, 25-30 parts of carbon black N774, 1.5-2.5 parts of anti-aging agent A, 1.5-2.5 parts of anti-aging agent D, 0.5-1.5 parts of anti-aging agent 4010NA, 2.5-3.5 parts of graphene, 3-5 parts of petroleum pitch, 0.5-1.5 parts of accelerator M, 1.5-2.5 parts of accelerator TMTD, and 1.5-2.5 partsof sulfur. The preparation method comprises six process steps of rubber mixing, calender cutting, extrusion, molding, vulcanization and packaging. The vulcanization temperature, time and pressure areadjusted in the vulcanization process, thereby fundamentally solving the problem of labor consumption and time consumption. In addition, because liquid water is low in cost and can be recycled, the production cost of an enterprise can be significantly reduced.

Description

[0001] 1. Technical field: [0002] The invention relates to a production process of rubber products, in particular to a ventilated circular clutch rubber airbag 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, elasticity and high thermal conductivity requirements, the current clutch rubber airbags are unsatisfactory in tear resistance, wear resistance, aging resistance and thermal and electrical conductivity. At present, the ventilated circular clutch rubber airbag is commonly used in the market. Its production process includes six processes including rubber mixing, calendering and cutting, extrusion, molding, vulcanization, and packaging. The ...

Problems solved by technology

At present, the vulcanization mode adopted by most enterprises at home and abroad is: use traditional vulcanization tanks for vulcanization, and use boilers to provide steam to vulcanize products, because vulcanization tanks cannot be quantitatively determined, especially in certain types of orders When the quantity is small or the demand for a certain product is small, the vulcanization of the vulcanization tank will consume a lot of energy, resulting in waste of resources and increased production costs

In addition, due to the large size of the vulcanization tank itself, the whole process from loading to unloading requires the cooperation of multiple people, which wastes manpower and poses a great safety hazard
