STUDY OF MODIFICATION OF BUTADIENE NITRILE POLYMER WITH COMMODE

Abstract

By preparing binary mixtures of butadiene-nitrile rubber with wood resin in different mass ratios, the volume consumption of these systems at temperatures of 100, 120, 150, 165 ℃ and under the influence of loads of 160-190 kg was studied. studies have shown that at 108 ℃, when the polymer has 5 mass parts commode, it acts as a modifier. as a result of odification, the technological properties of BNK, mainly chemical stability, increase one time compared to standard pezins. A recipe was drawn up on the basis of butadiene-nitrile polymer, and the obtained rubber mixture was vulcanized and the main properties of the vulcanizate were determined. As a result of the research, it was found that the wear coefficient of the obtained rubber increased by 19.6%, and the relative elongation increased by 44.4%.
