Ternary composite antiaging agent, manufacturing method of emulsion and application in chloroprene rubber

Abstract

The manufacture method of ternary compound antiaging agent, emulsion and application in neoprene rubber, is composed of a kind of bisphenol monoacrylate antiaging agent, a kind of hindered phenolic antiaging agent and a kind of sulfide antiaging agent according to the prescribed formulation Composite and mixed to make a ternary composite anti-aging agent; at room temperature, the ternary composite anti-aging agent prepared by the above method is dissolved in an organic solvent, and then the mixture of disproportionated abietic acid soap aqueous solution and sulfonic acid anionic surfactant aqueous solution is added The emulsifier made from the mixture is fully mixed and dispersed to make a three-component composite anti-aging agent emulsion; in the synthetic neoprene latex, it is added in a ratio of 1:0.03 to 0.07 according to the dry rubber mass of neoprene Ternary compound anti-aging agent emulsion. Aging experiment research shows: the chloroprene rubber product that has added the ternary composite anti-aging agent emulsion of the present invention to make, its rubber appearance color, Mooney viscosity, Mooney scorch time, mechanical strength performance index are all better than using anti-aging agent BHT Made of neoprene products.

Description

technical field [0001] The invention relates to a ternary composite anti-aging agent, a method for producing an emulsion and its application in the production of chloroprene rubber, so as to obtain a chloroprene rubber product with stable performance. The ternary composite anti-aging agent is made of a bisphenol monoacrylate antioxidant, a hindered phenolic antioxidant and a sulfide antioxidant as raw materials, and is made after compounding. Background technique [0002] Chloroprene rubber is an elastomer obtained by homopolymerization or copolymerization with 2-chloro-1,3-butadiene as the main raw material. It is proved by its crystallization behavior and infrared absorption spectrum analysis that the main chain of chloroprene rubber mainly contains linear chains of trans 2-chloro-2-butene units, such as: [0003] [0004] The mechanical properties of chloroprene rubber depend on the microstructure of the polymer, and the processing performance depends on the molar mas...
