With the progress of science and the development of technology, people are more and more aware of the importance of environmental protection, resource conservation and rapid economic development. The research and development of water-based non-toxic and low energy consumption coatings to replace the traditional oil-soluble coatings has become the investment hot spot of the coating industry all over the world. In the past, water-based paint paste was mainly used in textile pigment printing and watercolor ink for art advertising. Now it has been gradually extended to the fields of architectural coating, carton printing ink, metal coating, wood paint and so on.

Due to the different technical strength of domestic water-based coating manufacturers, the ability of compounding and using surfactants is also different. All enterprises adopt their own enterprise standards, and both good and bad product quality exist, which greatly affects the speed of comprehensive and balanced development of water-based coatings.

Although there are many varieties of pigments, limited by the application performance of water-based paint pastes, there are only a dozen or so commonly used among the dozens of applicable varieties. Each pigment has its own chemical structure and surface state. Therefore, the research and development of series surfactant compound products of special pigments can simplify the scientific research and production procedures of water-based paint pastes, The surfactant compound of various special pigments can be used quantitatively according to the percentage of different pigments, which is conducive to promoting the unification and improvement of the quality level of waterborne paint paste and the rapid development of waterborne paint industry.

The use of surfactant improves the wetting and dispersion ability of water-solid dispersion system to pigment particles, improves the degree of hydrophilic liquefaction of pigment particles, and the existence of steric resistance and charge repulsion in the adsorption layer protects the stability of suspended dispersion.

When using, multiple surfactants should be selected according to the chemical structure and HLB value to obtain better synergistic effect. The rapid development of waterborne coatings and pastes puts forward new challenges and requirements for the performance of surfactants. The research and development of high-efficiency, multi-functional and special series products will make the application of surfactants more widely.
