Industrial lignin reinforcing rubber and preparation method of industrial lignin reinforcing rubber

Abstract

The invention relates to industrial lignin reinforcing rubber and a preparation method of the industrial lignin reinforcing rubber. The industrial lignin reinforcing rubber is characterized in that 1, the industrial lignin reinforcing rubber comprises lignin dispersoid, rubber latex, a small number of plasticizers and operation oil or comprises multi-component lignin dispersoid, rubber latex, a small number of plasticizers and operation oil; 2, the lignin dispersoid is suspension of lignin in water, the weight part of the lignin is 5 to 30 percent, the multi-component lignin dispersoid is suspension of the lignin and inorganic fillers in water, and the weight proportion of the lignin to the water is (5-30):(95-70); and 3, in the lignin dispersoid and the multi-component lignin dispersoid, the lignin is hydroxymethylation modified dispersoid. The preparation method comprises the steps of 1. lignin preparation, 2, lignin dispersoid preparation, 3, rubber latex preparation, 4, cosedimentation and solidification and 5, industrial lignin reinforcing rubber obtaining. The industrial lignin reinforcing rubber and the preparation method have the advantages that the physical and mechanical properties of the rubber are not reduced, meanwhile, the drying processes in the lignin and rubber production process are combined, and the motive power consumption of rubber mixing is reduced.

Description

technical field

[0001] The invention relates to an industrial lignin reinforced rubber and a preparation method thereof. The invention belongs to the technical field of chemical materials and their preparation. Background technique

[0002] Traditionally, the production of rubber products requires the use of rubber internal mixers, open mills, continuous screw mixers and other equipment to combine raw rubber with reinforcing agents, fillers, vulcanization accelerators, antioxidants, operating oils, and functional aids. Mixing with additives, etc., to endow the rubber compound with specific technological properties and specific physical and chemical properties of the vulcanized rubber. This mixing method is also called dry mixing. This mixing process requires a lot of power. Reinforcing agent and operating oil are the most widely used additives in the rubber industry, and the power consumed by kneading reinforcing agent and operating oil accounts for more than 40% of the ru...
