Abstract

The invention belongs to the technical field of waste rubber regeneration, and provides an environment-friendly waste rubber regenerant and a preparation method thereof, the environment-friendly waste rubber regenerant is composed of an activating agent, a softening agent and a tackifier which are uniformly mixed; the weight parts of the components are as follows: 10-25 parts of the activating agent, 60-80 parts of the softening agent and 10-15 parts of the tackifier; the activating agent is prepared by uniformly mixing octadecylamine, deodorized distillate, stearic acid and an accelerant NS according to the mass ratio of (2 to 5): (5 to 11.25): (1 to 4): (2 to 7.5). The activating agent, the softening agent and the tackifier are applied to waste rubber regeneration, odor is small, toxic gas emission in the rubber regeneration process is reduced, the rubber swelling property is good, and the stability and the plasticizing effect are good when the activating agent, the softening agent and the tackifier are applied to waste rubber regeneration; the polycyclic aromatic hydrocarbon content meets the environmental protection technical requirements at home and abroad, the environment-friendly waste rubber regenerant has the advantages of favorable mechanical properties, simple preparation process, easiness in product control and no pollution in preparation process, thereby being favorable for large-scale industrial production and application.

Description

technical field [0001] The invention belongs to the technical field of waste rubber regeneration, and in particular relates to an environment-friendly waste rubber regeneration agent and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, the rubber industry has developed rapidly and is widely used in tires, shoe soles and latex products. The consumption of rubber continues to increase, which aggravates the shortage of rubber resources. At the same time, a large amount of waste rubber is also produced. Aggravating the pollution to the environment, the effective treatment and comprehensive utilization of waste rubber is not only beneficial to environmental protection, but also enables the regeneration of valuable rubber resources. my country is the largest producer of waste rubber, among which the total amount of waste tire rubber accounts for more than 70% of the total waste rubber. According to data, in 2020, the numbe...
