| titleOfInvention | Nitrile rubber production process |
| abstract | The invention relates to the technical field of rubber production, aiming to provide an improved nitrile rubber production process, which comprises polymerization, degassing and condensation. Raw materials including acrylonitrile, butadiene, desalinated and deoxidized water, condensed water and molecular weight regulators are fed into a polymerization position, convergence is carried out in a header pipe at the polymerization position, the converged mixture is pre-emulsified sequentially through a pipe pump and a pipe mixer, heat exchange is carried out through an ammonia-cooling heat exchanger for cooling, the cooled mixture, initiator emulsion and activator solution are sequentially fed into a plurality of reactors for polymerization to produce latex, the latex taken out of the reactorsand terminating defoamer solution are fed into a maturing reactor and are fully mixed when the rate of polymerization and conversion reaches 70 plus or minus 5 percent, and the mixture is then fed into a degassing tower to be degassed and into a condensation reactor for condensation. The problem of blockage of the heat exchanger can be avoided, the process is simple, the production process is stable and economical, the Mooney of rubber can be controlled easily, and the produced nitrile rubber has high quality. |
