High-temperature-resistant pressing-resistant anti-deformation rubber used for mining machinery buffering cushion

Abstract

The invention belongs to the technical field of rubber materials, and particularly relates to a high-temperature-resistant pressing-resistant anti-deformation rubber used for a mining machinery buffering cushion. The rubber is prepared from the following ingredients: matrix rubber, silicone oil, butadiene, zinc powder, silicon dioxide powder, aluminium oxide, white carbon black, magnesium oxide, stearic acid, a high-temperature modifier, an antiager, a coupling agent, a cross-linking agent and a catalyst, wherein the matrix rubber comprises butadiene rubber, nitrile rubber, chloroprene rubberand butadiene styrene rubber; the antiager selects an antiager RD or an antiager BLE; the coupling agent is a silane coupling agent; the cross-linking agent is methyl tripropanone oxime silane. The rubber is treated through multiple technologies including kneading, mixing, banburying, calendaring, vulcanization and the like. The rubber has excellent high-temperature-resistant performance and pressing-resistant performance and good material rebound resilience and is very suitable for manufacturing buffering cushions used for large equipment including mining machinery and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a high-temperature-resistant, pressure-resistant and anti-deformation rubber for mining machinery buffer pads. Background technique [0002] Rubber is a reversibly deformable polymer material with high elasticity. Under normal conditions, it can produce large deformation under the action of small external force, and the deformation can recover quickly after the external force disappears. In mechanical equipment, many parts are often impacted by external forces, so it is necessary to install anti-collision buffer parts. Rubber materials have outstanding elastic properties, which can effectively absorb the impact of external forces and convert them into their own deformation, and when the external force disappears Automatic recovery. Therefore, the buffer pads and other structures in mechanical equipment mainly use rubber products. [0003] Conventional rub...

AI Technical Summary

Problems solved by technology

[0003] Conventional rubber materials have good resilience, but the reversible deformation of the material will be affected by temperature. When the temperature exceeds the limit of the rubber material itself, the resilience of the rubber material will be significantly reduced, thereby changing the elastic deformation into rigid deformation. The cushion pad loses the cushioning and anti-collision effect

In some mining machinery, materials such as buffer pads are under greater pressure than normal conditions, and the temperature is high in summer, and the mechanical equipment itself will generate heat. This high-pressure and high-temperature condition will significantly reduce the mechanical properties and rebound of the buffer pad rubber. Effect
