AI Technical Summary

Problems solved by technology

When there is a certain stress in the environment, this thermodynamic balance will be destroyed, and the emulsifier molecules will be desorbed, resulting in the adhesion between the polymer particles and the loss of the stability of the polymer latex; in the process of latex film formation, Ordinary emulsifiers are small molecules remaining in the polymer solid, which can migrate to the surface of the film and establish a thermodynamic equilibrium that matches the environment, which leads to a decrease in the water resistance of the polymer film

Abstract

The invention provides a double-bond-containing alcohol ether sulfate which can be used as a responsive emulsifier, and a production method and applications thereof. The structure of the alcohol ether sulfate is R1-(CO)n-(DO)x-(FO)y-(GO)z-SO3M. The double-bond-containing responsive emulsifier also contains an aryl group, and does not contain alkylphenol or an alkylphenol polyester group. The double-bond-containing alcohol ether sulfate having the above structure does not contain European Union prescribed APEO (alkylphenol ethoxylates) and has the performances of an aromatic compound, and has a better pigment filler disperse color development property than aliphatic compounds of a same kind, can be used as a surfactant, an emulsifier for emulsion polymerization, or a vinyl monomer polymerization modifier, and is in favor of implementing a polymerization reaction and synthesizing polymers to obtain products having a good mechanical stability and a good paint film water resistance as the responsive emulsifier.

Description

technical field [0001] The invention relates to a compound that can be used as a reactive emulsifier, in particular to an alcohol ether sulfate containing a double bond and an aromatic ring, a salt, and a production method thereof. Background technique [0002] Water-based emulsion polymerization technology has been used to produce polymers for many years. Emulsion polymerization has the advantages of fast reaction speed, easy diffusion of polymerization heat, preparation of high-viscosity polymers, and reduction of environmental pollution. The synthesis of water-based emulsion needs to be realized by emulsifier. The function of emulsifier is: when it is dispersed on the surface of dispersoid, it forms a thin film or electric double layer, which can make the dispersed phase charged, so that it can prevent the dispersion of the dispersed phase. The droplets coagulate with each other, making the formed emulsion more stable. Emulsion polymerization is a polymerization reaction...
