Abstract

The invention relates to an outer glue material of a rubber pneumatic bag for automobile air suspensions and a preparation method thereof. The outer glue material of the rubber pneumatic bag for automobile air suspensions comprises the following components in parts by weight: 20-80 parts of natural rubber (NR), 30-70 parts of chloroprene rubber (CR), 5-40 parts of butadiene rubber (BR), 4-6 parts of a surfactant, 0.3-10 parts of an antiager, 3-10 parts of a vulcanizing agent, 10-100 parts of nano inorganic filler, 20-40 parts of carbon black, and 2 parts of a homogenizing agent. The outer glue material disclosed by the invention has the following beneficial effects that in the outer glue material of a rubber pneumatic bag for automobile air suspensions, the rubber is high in strength, high in surrender and good in low temperature resistance, so that the endurance life of a finished rack product is greater than 4.5 million times, therefore, the outer glue material of a rubber pneumatic bag for automobile air suspensions disclosed by the invention meets and exceeds the requirements of operating conditions of outer glue materials of rubber pneumatic bags for automobile air suspensions.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a formula of a rubber airbag outer layer rubber material for an automobile air suspension and a preparation method thereof. Background technique [0002] A typical automotive air suspension is mainly composed of air spring components (including air springs, air compressors, air storage tanks, etc.), height control components (body height adjustment valves, height sensors), guide rods (thrust rods), lateral stabilizers , shock absorbers and buffer limit parts and other components. The leaf spring suspension system can no longer meet the requirements of use, and one of the development directions is to use air suspension. [0003] The air spring is an elastic element and an important part of the air suspension. According to the shape, it is divided into three categories: capsule type, membrane type and sleeve type. The air spring uses air as the medium and has variable s...
