Problems solved by technology

[0002] When the car brakes, a large amount of heat is generated between the brake pad and the rubber airbag, which causes local high temperature on the outer edge of the rubber airbag, which has a great impact on the service life of the rubber airbag made of ordinary rubber materials.
For this reason, the automotive annular expansion brakes involved in Chinese patents 85103272, 96201435.4, and 01232407.8 all adopt heat insulation treatment in the elastic rubber airbags included in it, that is, fill with a heat insulating layer between the rubber airbags and the brake pads, so as to Keep the temperature of the rubber airbag from being too high during braking, which will affect its service life
However, due to the limited thickness of the filled thermal insulation layer, the thermal insulation effect is not very obvious
In addition, Chinese patent 99219433.4 adopts an overhead support structure in order to solve the life problem of rubber airbags caused by temperature, but the structure is complicated and the reliability of temperature is difficult to guarantee

Embodiment Construction

[0024] As shown in the accompanying drawing, the specific process is as follows:

[0025] 1) Raw rubber mastication: In order to properly improve the plasticity of raw rubber, use an open rubber mixer with low roll temperature and variable roll distance (5-8mm to 1-1.5mm) to carry out mastication;

[0026] 2) Batching: crush the raw material components in the rubber formula other than synthetic raw rubber, that is, the compounding agent, and then mix with the raw rubber after mastication according to the mass parts specified in the rubber formula. glue;

[0027] 3) Mixing: use an open mixer for mixing, and the temperature of the mixing drum is always controlled at 50-60°C;

[0028] First, widen the roller distance of the mixer to 5-8mm, add active agent, vulcanizing agent and anti-aging agent and mix with synthetic raw rubber for 4 minutes; then add reinforcing filler, tackifier, stearic acid and mix for 8 minutes; then add plasticizer and mix for 1 minute; finally add accel...

Abstract

The present invention discloses the composition and producing process of rubber for brake. The rubber consists of synthetic rubber, sulfurizing agent, antiageing agent, activator, tackifier, stearic acid, promoter, reinforcing agent, platicizer, etc. The production process includes raw rubber plastication, mixing, hotmixing, forming and sulfurizing, and can obtain optimal material combination. The rubber product has raised stability against heat, oxygen and ageing, heat resistance, airtight performance, etc.

Description

Technical field [0001] The invention relates to a method for preparing rubber, in particular to a brake rubber formula and a processing technology thereof. Background technique [0002] When the car brakes, a large amount of heat is generated between the brake pad and the rubber airbag, which causes local high temperature on the outer edge of the rubber airbag, which has a great impact on the service life of the rubber airbag made of ordinary rubber materials. For this reason, the automotive annular expansion brakes involved in Chinese patents 85103272, 96201435.4, and 01232407.8 all adopt heat insulation treatment in the elastic rubber airbags included in it, that is, fill with a heat insulating layer between the rubber airbags and the brake pads, so as to The temperature of the rubber airbag during braking will not be too high, thereby affecting its service life. However, due to the limited thickness of the filled heat insulation layer, the heat insulation effect is not v...
