AI Technical Summary

Problems solved by technology

The main traditional method is to produce aromatic hydrocarbon oil. Because it contains polycyclic aromatic hydrocarbon compounds that are carcinogenic to human body, various rubber products produced by it have not met the limit value requirements for polycyclic aromatic hydrocarbon content in rubber products stipulated in the EU REACH environmental protection law.

Abstract

The invention discloses a regenerated rubber softener and a preparation method of the softener. The regenerated rubber softener comprises the following raw materials: peel, walnut shells, chestnut shells, phosphoric acid, calcium chloride, 70% ethanol, glycerol, glycerin and water. The preparation method comprises the steps of: grinding the peel, adding the peel, phosphoric acid and calcium chloride into the water for uniform stirring and soaking for 30-40min to form a mixed solution, pouring the mixed solution into a distiller for steam distillation to form an extract A, mixing and grinding the walnut shells and the chestnut shells to form a mixed solid, mixing the mixed solid, 70% ethanol and glycerol for distillation to form an extract B, and mixing the extract A, the extract B and glycerin to form the regenerated rubber softener. The regenerated rubber softener can substitute the traditional rubber softener such as coal tar and aromatic oil.

Description

technical field [0001] The invention relates to the field of regenerated rubber preparation, in particular to a regenerated rubber softener and a preparation method thereof. Background technique [0002] China is a country that is relatively short of raw rubber resources. About 50% of China's annual consumption of reclaimed rubber needs to be imported. Finding the source of rubber raw materials and their substitute materials is an unremitting task for China. Therefore, carefully and properly disposing of waste rubber has extremely far-reaching positive and practical significance for making full use of renewable resources, getting rid of the lack of natural resources, reducing environmental pollution, and improving the living environment of the people. Reclaimed rubber has always been an important raw material for the world's rubber industry. On the one hand, it can replace rubber and alleviate the serious shortage of natural rubber; on the other hand, it enables waste rubber...
