Abstract

The invention relates to a softener for regenerated rubber, which is a mixture of 50-70 parts by weight of vegetable oil, 50-70 parts by weight of glycerin, 5-15 parts by weight of rosin and 0.1-0.2 part by weight of diglycol. The softener for the regenerated rubber, which is prepared from non-toxic and harmless substances, can completely substitute a coal tar-series softener, and the regenerated rubber which is produced by using the softener can completely reach various standards stipulated by REACH (registration, evaluation, authorization and restriction of chemicals) European Union regulations.

Description

technical field [0001] The invention relates to a softener for regenerated rubber. Background technique [0002] In today's world, the development of low-carbon economy has become an important trend and the focus of widespread attention. At present, people generally realize that the development of low-carbon economy, green economy and circular economy is an economic form of harmonious development of economy and environment, which will guide new consumer demand, trigger new technological revolution and management innovation, and open up a new era of world economy. growth point. With the rapid development of the economy, the rubber industry is changing with each passing day. From the aerospace industry to the transportation industry, from industrial and agricultural production to daily life, rubber products are everywhere. my country is a big country with rapid development of rubber industry, but it is also a country with serious shortage of rubber resources. The shortage o...
