Problems solved by technology

However, the minimum film-forming temperature of emulsion-type and soap-free emulsion-type resins is relatively high, generally above 15°C, and it is difficult to form a good film at low temperature without adding film-forming aids, which will affect the coating performance.
However, the film-forming aid is a kind of temporary plasticizer that is easy to disappear and has a certain volatilization rate. The price is relatively high, and the cost of the product will increase after addition. Bioresin is more realistic

Abstract

The invention provides a nonsoap nuclear shell latex type amphipathic polymer resin, which is polymerized from methyl methacrylate, styrene, methyl methacrylate, butyl methacrylate, butyl acrylate, hydroxypropyl methacrylate, hydroxyethyl methacrylate, acrylamide, diacetone acrylamide and other monomers. The nonsoap nuclear shell latex type amphipathic polymer resin is used as a main film forming material for a paint and is combined with various inorganic macromolecular fillers to prepare the paint; the prepared paint integrates decoration, dampness regulation, permeability, heat insulation, dewing resistance, water and alkali resistance, antisepsis and the like, and can also prevent a coating film from falling off caused by various leakage and water condensation of a wall body so that the coating film is more lasting and durable; and the paint contains no organic solvent and no emulsifier, is safer and more environment-friendly, and has more superior coating property.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and relates to a polymer resin, in particular to a soap-free core-shell emulsion type amphiphilic polymer resin with hydrophilicity and lipophilicity and a preparation method thereof, and the invention also relates to the soap-free core-shell emulsion type amphiphilic polymer resin Application of shell emulsion type amphiphilic polymer resin in the production of functional moisture-regulating coatings. technical background [0002] Relative air humidity is an important parameter to measure the indoor environment. It is closely related to human health and work and life. If it is too high or too low, it will affect people's normal life. Considering various factors such as microbial growth, human disease, item deterioration, and comfort, it is recognized that the optimal relative humidity range is 40% to 60%. It is of great significance to improve the environment, improve the preservation qu...
