Non-ionic surfactants are widely used in the rubber industry, either directly as auxiliaries or as auxiliary agents. For example, in the production of latex products, non-ionic surfactants are used as dispersant, emulsifier, wetting agent, stabilizer, thickener, coagulant, defoamer, etc.
dispersant
Common dispersants are nonionic surfactants such as polyoxyethylene laurate.
emulsifier
When using water-insoluble liquid compounds in latex, emulsifiers must be added. Commonly used emulsifiers are: non-ionic polyether, polysulfide and so on.
Wetting agent
In order to improve the wettability of latex, wetting agents should be added to it. The commonly used wetting agents are nonylphenol polyoxyethylene ether, sorbitan fatty acid ester (Span), fatty alcohol polyoxyethylene ether and other non-ionic surfactants.
stabilizer
In order to stabilize the latex and prevent condensation, it is necessary to add a stabilizer to the latex. The commonly used stabilizers are fatty alcohol polyoxyethylene ether nonionic surfactants and mixed glycerin soap.
thickener
In order to increase the viscosity of the latex, reduce the fluidity and improve the processing performance, it is necessary to add a thickener.
defoamer
In order to eliminate the foam produced in the latex production process, defoamer is added. Commonly used defoamer such as: polyether type defoamer.
In the production of vulcanized rubber, a series of complex agents need to be added, most of them are not surfactants, but in order to increase their efficacy, non-ionic surfactants need to be added as auxiliary agents to play a synergistic and synergistic effect on the complex.
