High-strength rubber lining formula

Abstract

The invention discloses a high-strength rubber lining formula, which comprises the following components in parts by weight: 18-22 parts of No. ‑14 parts, 3‑7 parts of white carbon black, 10‑12 parts of paraffin, 6‑8 parts of clay, 3‑7 parts of iron oxide, 6‑8 parts of calcium carbonate, 2‑3 parts of silane coupling agent, quick decomposing agent 2-3 parts, 2-8 parts of reclaimed rubber short fiber, 1-3 parts of sulfur, 1-2 parts of anti-aging agent, 0.6-1 part of active agent, 1-3 parts of adhesive, 0.6-1 part of accelerator, softening Dose 10-14 parts. In the present invention, by adding a silane coupling agent to the rubber formula, the silane coupling agent reacts with the hydroxyl groups on the surface of the white carbon black, so that the white carbon black changes from hydrophilic to hydrophobic, thereby increasing the bond between white carbon black and rubber. Compatibility and bonding force make the product tear-resistant, impact-resistant and wear-resistant. At the same time, an adhesive is added in the utility model, and the combination of the adhesive and the silane coupling agent improves the adhesive force at high temperature and facilitates the bonding of the lining and the steel base.

Description

technical field [0001] The invention relates to a formula, in particular to a high-strength rubber lining formula. Background technique [0002] With the development of hard rubber lining technology, its application field is also expanding continuously, and different rubber linings are produced according to the requirements of various fields. At present, the rapid development of my country's national economy requires that the mining and development of metal mine resources be accelerated. Higher requirements are put forward in terms of wear resistance, tear resistance and impact resistance for mining equipment lining rubber and mine slurry pipeline lining rubber. The traditional rubber lining formula is made of ordinary rubber and carbon black for reinforcement, which has low performance in terms of tear resistance, impact resistance and wear resistance, especially at high temperatures, which is easy to fall off, which is not conducive to long-term work and long product life. ...
