Abstract

The invention relates to tire reclaimed rubber and a preparation method thereof. The tire reclaimed rubber comprises the following components in parts by weight: 90-120 parts of rubber powder, 2-3 parts of resin, 9-12 parts of rosin, 0.8-1.1 parts of an activating agent, 1-3 parts of sulfur, 1-2 parts of a regenerating agent, 2-5 parts of calcium carbonate, 1-4 parts of argil, 1-5 parts of a titanate coupling agent, 3-4 parts of tall oil and 38-45 parts of aromatic hydrocarbon oil. By adopting the design, the sulfur and the resin are put into the reclaimed rubber, so that the overall strengthof the reclaimed rubber is improved; meanwhile on the basis of a preparation process, a seventh zone, namely a shock chilling zone, is added, so that molecules inside the reclaimed rubber can be rapidly stabilized, finally the reclaimed rubber is slowly heated to normal temperature in a normal temperature zone, then the overall toughness of the reclaimed rubber is improved, and requirements of high-quality rubber products are met.

Description

technical field [0001] The invention relates to rubber and a preparation method thereof, in particular to a tire reclaimed rubber and a preparation method thereof. Background technique [0002] Reclaimed rubber is processed from the vulcanized scraps in the production of rubber products. It has a certain degree of plasticity and can be reused. Reclaimed rubber for short. According to the different waste rubber used, reclaimed rubber is divided into outer tires, inner tubes, rubber shoes and so on. [0003] Reclaimed rubber can partially replace raw rubber for rubber products, saving raw rubber and carbon black is also beneficial to improve processing performance and certain properties of rubber products. The regeneration process is a process in which waste rubber breaks part of the molecular chains and cross-linking points of vulcanized rubber under the combined action of plasticizers (softeners and activators), oxygen, heat and mechanical shear. The softener plays the ro...
