①The emulsion polymer uses water as the dispersion medium, has low VOC, is non-toxic, safe, and has no fire hazard.
②The molecular weight of emulsion polymer is relatively high, which can reach above 105, but the molecular weight has nothing to do with viscosity. After the film is formed, it has a higher film strength.
③The viscosity of the system is low, and it can be pumped in pipelines during production, which improves the efficiency of the processing and preparation of latex coatings.
④It has a special film-forming mechanism. The emulsion is a water dispersion system, and its film-forming is different from a homogeneous organic polymer solution system. It is a process of fusion after the particles are compressed and deformed as the water evaporates, so it has a certain degree of air permeability. sex.
⑤The composition of the emulsion polymer contains emulsifiers, initiators, buffers and other small molecular compounds, which are easily soluble in water and have an impact on the water resistance and alkali resistance of the coatings prepared with them. This point cannot be ignored when choosing a polymer.
