| titleOfInvention | A high-efficiency molecular chain scission agent and its application in the preparation of sulfur-modified chloroprene rubber |
| abstract | The invention belongs to the technical field of chloroprene rubber preparation, and aims to provide a high-efficiency molecular chain scission agent and its application in preparing sulfur-adjusted chloroprene rubber. A mixture of one or both of the lams. Application in the preparation of sulfur-adjusted neoprene rubber. The molecular weight regulator is prepared by mixing tetraethylthiuram disulfide and tetrabutylthiuram disulfide. The amount of the two can be changed within a certain range, but the total amount remains unchanged, and is added to the same oil phase , to obtain neoprene with suitable Mooney viscosity. Physical tests such as strength, constant elongation and elongation are carried out on the dry glue. The invention not only further simplifies the preparation method of the chain scission agent, but also is more conducive to production practice, and adopts the antioxidant system supplemented by hindered phenol and phosphite to ensure that the raw rubber has better anti-aging properties, and still remains after aging for 3 days. It has good mechanical properties, such as the tensile strength is basically above 23MP, which makes the product performance better. |
