Abstract

The invention relates to a rubber composite material filled by cardanol modified lignin and a preparation method thereof. The rubber composite material is characterized by being made of 100 parts by weight of rubber and 10-200 parts by weight of cardanol modified lignin. The rubber is natural rubber, polyisoprene rubber, styrene butadiene rubber, butadiene rubber, 1, 2 polybutadiene, an ethylene propylene diene monomer, butyl rubber, nitrile rubber or neoprene, or a combinationof two or more of natural rubber, polyisoprene rubber, styrene butadiene rubber, butadiene rubber, 1, 2 polybutadiene, an ethylene propylene diene monomer, butyl rubber, nitrile rubber and neoprene. The cardanol modified lignin contains hydroxymethyl and unsaturated alkyl long chain functional groups. The cardanol modified lignin is obtained by employing ormaldehyde and cardanol as modifiers to modify a black liquor or pure lignin. According to the invention, environment friendly and renewable lignin and cardanol are taken as the main raw materials, which can improve the mechanical properties of the rubber products and lower the rubber product cost. Thus, the rubber composite material filled by cardanol modified lignin has economic value and social significance.

Description

technical field [0001] The invention relates to a rubber composite material and a preparation method thereof, in particular to a cardanol-modified lignin-filled rubber composite material and a preparation method thereof. Belongs to the technical field of polymer materials, Background technique [0002] The application of lignin in the rubber industry as a natural polymer with high surface activity shows the advantages of less dust pollution, environmentally friendly production methods, and low cost, which provides an effective way for the sustainable development of the rubber industry. With people's increasing emphasis on low-carbon environmental protection, the application of lignin in the rubber industry can better reflect its significant economic value and social significance. The research on lignin as a rubber reinforcing agent at home and abroad has experienced more than 70 years of development. The processing technology of lignin-filled rubber and the modification of ...
