SU1353783A1 - Promoter of foaming rubber mixes on base of carbochain rubbers - Google Patents

Abstract

The invention relates to the field of obtaining porous rubbers based on chain-chain rubbers. The invention allows to increase the maximum degree of foaming of rubber mixtures based on chain-chain rubber containing azodiisobutyronitrile by using oligoether acrylates, for example, D-35, TGM-3, TMGF-11, as a promoter of foaming. 12 tab.

Description

13537832

The invention relates to pore formation technologies is determined by

processing of elastomers, namely, the technology of porous rubber products.

The purpose of the invention is to increase the maximum degree of foaming of rubber mixtures based on chain-chain rubber containing azodiisobutyronitrile (porophore CHZ-57) as a foaming agent.

In tab. 1-11 rubber compounds are manufactured in a known manner using rubber-mixing equipment. For every 10

instrument for determining the kinetic characteristics of the process of pore formation in a glycerol medium.

The examples show the possibility of increasing the dosage of fillers in porous rubber mixtures (Tables 5-6).
