Abstract

The invention relates to a method for preparing unsaturated fatty acid zinc salt reinforced natural rubber in in-situ reaction. The method comprises the following specific steps: adding nano-zinc oxide, a proper amount of coupling agent, an anionic surfactant and emulsion hydroxyethyl methylacrylate rubber, and preparing nano-zinc oxide emulsion dispersion by adopting stirring and ultrasonic dispersion; stabilizing emulsion natural rubber by adopting a proper amount of nonionic surfactant, uniformly mixing the nano-zinc oxide emulsion dispersion in the emulsion natural rubber, and dropwise adding an unsaturated fatty acid and an initiation cross-linking agent, thereby obtaining an in-situ reaction unsaturated fatty acid zinc salt-natural rubber composite material in a rubber latex state; further solidifying, pressing, washing, drying and performing other standard China rubber conventional processing technologies on the composite material, thereby obtaining an unsaturated fatty acid zinc salt-natural rubber composite material in a dry glue state. The composite material prepared by the method is good in performance.

Description

technical field

[0001] The present invention relates to a kind of preparation method of in-situ generated unsaturated fatty acid zinc salt reinforced natural rubber, in particular to a method utilizing the excellent compatibility between hydroxyethyl methacrylate rubber and natural rubber and the compatibility of unsaturated fatty acid with natural rubber The invention relates to a method for preparing a reactive unsaturated fatty acid zinc salt reinforced natural rubber composite material through in-situ chemical reaction of nanometer zinc oxide, belonging to the technical field of rubber composite material production. Background technique

[0002] Natural rubber (NR) is a non-polar rubber, and it needs to be reinforced with fillers when it is used alone as a rubber material. At present, the reinforcing fillers widely used in the rubber industry mainly include carbon black, silica, fiber, clay, calcium carbonate, etc. For a long time, zinc oxide was only used as a vulcaniz...
