Reclaiming agent, reclaimed rubber prepared therefrom, and preparation method of reclaimed rubber

Abstract

The invention discloses a reclaiming agent, reclaimed rubber prepared therefrom, and a preparation method of the claimed rubber. The reclaiming agent comprises the following components in parts by mass: 0.5-3 parts of regenerated activator, 5-20 parts of regenerated swelling agent and 1-10 parts of other processing aids. The reclaiming agent, the reclaimed rubber and the preparation method of the claimed rubber have the beneficial effects that crumb rubber powder, used environment-friendly regenerated activator and the swelling agent are uniformly mixed and then added to rubber mixing equipments, such as an open mill and an extruder to reclaim under the condition from room temperature to 50 DEG C in a high-speed mixer in the process of preparing the environment-friendly reclaimed rubber; the regenerating temperature is low, so that bad objectionable odor and staining property of the traditional reclaimed rubber are removed. Compared with the traditional reclaimed rubber, the environment-friendly reclaimed rubber has the advantages that the mechanical property and the processing property are not reduced by a test; chemicals which are not permitted to use are not contained in 'REACH'; the reclaiming agent is simple and efficient in processing technology, and fewer in regenerating procedure; various rubber mixing equipments can carry out regeneration operation.

Description

technical field [0001] The invention belongs to the recycling field of waste rubber, and relates to a regenerant, regenerated rubber prepared by using the regenerant and a preparation method. Background technique [0002] The chemical reaction between the rubber macromolecular chain and the vulcanizing agent such as sulfur, accelerator, etc. makes the chemical cross-linking points between the rubber macromolecular chains change from a linear one-dimensional structure to a three-dimensional space network structure, improving the physical and mechanical properties of the rubber, but cross-linking The combined rubber cannot be naturally degraded for a long time after being discarded, and most of it becomes industrial waste. In the case of high prices, shortage of resources and accelerated deterioration of the environment, it is of great significance to reduce the environmental burden, efficiently recycle waste rubber resources, and realize the green cycle of basic raw material ...

AI Technical Summary

Problems solved by technology

Although the De-link regenerant invented abroad can regenerate waste rubber under the action of low temperature and mechanical force, it is difficult to promote it in my country because of its high price and the large rebound of Mooney viscosity in the later stage.
