Description
Technical Field
The invention relates to the technical field of chemical auxiliary agents, in particular to a fatty alcohol high-molecular emulsifier and a preparation method thereof.
Background
Emulsifiers are compounds which form stable emulsions of mixtures of two or more immiscible components. The principle of action is that during the emulsification process, the dispersed phase is dispersed in the form of droplets (micron-sized) in the continuous phase, and the emulsifier reduces the interfacial tension of the components in the mixed system and forms a firmer film on the surface of the droplets or forms an electric double layer on the surface of the droplets due to the electric charge given by the emulsifier, thus preventing the droplets from aggregating with each other and maintaining a uniform emulsion.
Essentially, emulsifiers are a class of surfactants. Common emulsifiers are low molecular weight emulsifiers and high molecular weight emulsifiers. The low molecular weight emulsifier is commonly used in emulsion polymerization, and because the lipophilic end of the low molecular weight emulsifier is connected to the surface of emulsion particles in a physical adsorption mode, the emulsion has the problems of electrolyte intolerance, easy flocculation and the like. Furthermore, the presence of low molecular weight compounds can have a plasticizing effect on the emulsion coating film, thereby affecting the properties of the coating film such as water resistance, strength and transparency, and limiting the application of the polymer emulsion.
Polymeric emulsifiers are just able to overcome the above disadvantages. The segment of the lipophilic part of the high molecular emulsifier can be selected from the same or similar monomers as the polymer to be prepared. According to a similar compatibility principle, the segment is anchored in the latex particle, not only adsorbed on the surface of the latex particle. A part of the polymeric emulsifier is also possible to copolymerize with the monomer, which greatly improves the bonding strength. The high molecular emulsifier not only stabilizes the latex through a hydration layer (ionic type is electrostatic repulsion), but also through steric hindrance effect, so that the electrolyte resistance of the latex is improved, and the stability of the latex is also improved. Because the molecular weight and the molecular structure of the high molecular emulsifier are similar to those of the polymer to be prepared, no plasticizing effect is generated on the coating film, and the water resistance, the strength and other properties of the coating film can be effectively improved. However, the existing high molecular emulsifier is mainly developed by foreign companies, such as non reputations, Ciba and other foreign enterprises, has long production period and high cost, and is mostly applied to industries with higher product price, such as the cosmetic industry.
