Rubber cushion pad

Abstract

The invention relates to a rubber cushion pad. The rubber cushion pad consists of the following components in parts by weight: 80 to 90 parts of natural rubber, 20 to 30 parts of polyurethane rubber,20 to 30 parts of talcum powder, 10 to 20 parts of silica-alumina carbon black, 3 to 5 parts of lignocellulose, 1 to 3 parts of sulphur, 3 to 5 parts of zinc oxide, 0.5 to 0.9 part of stearic acid, 1to 3 parts of an anti-aging agent, 4 to 6 parts of high aromatic oil and 2 to 4 parts of paraffin, wherein the anti-aging agent is a mixture of a p-phenylenediamine anti-aging agent and a di-hydro-quinoline anti-aging agent, and the mass ratio of the p-phenylenediamine anti-aging agent to the di-hydro-quinoline anti-aging agent is (1.3 to 1.9): 1. The rubber cushion pad has the advantages that therubber cushion pad takes natural rubber and polyurethane rubber as main raw materials, lignocellulose and the anti-aging agent are added into the main raw materials, and the raw materials have synergistic effect, so that the prepared rubber cushion pad has the characteristics of abrasion resistance, low creep, fatigue resistance and good cushioning effect.

Description

technical field [0001] The invention belongs to the technical field of rubber products, in particular to a rubber damping pad. Background technique [0002] Rubber shock absorbing pad products are used to eliminate or reduce the transmission of mechanical vibration, achieve shock absorption, noise reduction and reduce the damage caused by impact, and are used in a wide range of applications, such as elevators, high-speed rail, mechanical equipment, vehicles, ships, etc. [0003] In some cases, the generation of vibration will bring some adverse effects, for example, machine vibration will generate noise and increase energy consumption. In order to reduce these adverse effects, some vibration damping elements are usually used to isolate the transmission of vibration and absorb the vibration caused shock. Shock-absorbing pads are the most common type of shock-absorbing components. They are usually used as supports or connectors and are widely used in various mechanical equipm...
