Abstract

The invention discloses a high-performance environment-friendly rubber dispersing agent. the dispersing agent comprises the following components in parts by weight: 35-45 parts of plant-based soybean oil acid, 2-10 parts of lauryl sodium sulfate, 6-16 parts of higher alcohols, 25-35 parts of erucyl amide, and 2-5 parts of microcrystalline wax. The dispersing agent is simple and safe to prepare, the influence of dust on a human body is reduced, and the prepared dispersing agent has excellent processing and usage performances, higher cost performance and is green and environment-friendly on the premise of keeping good dispersion effect.

Description

technical field [0001] The invention relates to a dispersant, in particular to a high-performance environment-friendly rubber dispersant. Background technique [0002] Dispersant is one of the indispensable ingredients in the production of rubber products. It has always played a stable and important role in the market. Dispersant is a multi-effect rubber compound processing aid. Its performance is mainly manifested in its strong dispersion effect. , can accelerate and improve the dispersion of carbon black, white carbon black and other fillers, shorten the mixing cycle, and improve the mixing efficiency. The Mooney viscosity can also prevent the rubber from scorching, which is beneficial to increase the fluidity of the rubber; this dispersant allows various materials to give full play to the matching effect, and fully realizes the strong physical properties and use requirements of the rubber formula design; [0003] At present, whether domestic or foreign, rubber dispersant...
