Problems solved by technology

Inorganic coatings have high hardness, good water absorption and wear resistance, but large thixotropy, poor leveling and decorative properties, poor elasticity, and easy cracking
The emulsion-type humidity-controlling paint in the organic category has good flexibility and decoration, but because this type of emulsion resin is a thermoplastic hydrophobic resin, it tends to become soft and sticky at high temperatures, and brittle and cracked at low temperatures; Slow, and poor water resistance, easy to drop powder, foam, or even fall off when exposed to water; organic polymer glue type humidity-controlling coatings, because the resin is completely water-soluble, so the coating gradually dissolves and falls off when exposed to water, so the humidity-conditioning coatings currently researched Coatings have not been commercialized in large quantities due to the above disadvantages

Abstract

The invention provides a latex type amphiphilic polymer resin, which is formed by polymerizing unsaturated acid alkyl, methyl methacrylate, styrene, butyl methacrylate, butyl acrylate, hydroxypropyl methacrylate, ethylene glycol methacrylate, acrylamide, diacetone-acryloamide and other monomers. The paint which takes the latex type amphiphilic polymer resin as a main film forming material and combines with inorganic polymer stuffing integrates with decorative property, humidifying property, permeability, heat preservation, condensation prevention, water and alkali resistance, bacterium resistance and so on, and can prevent the paint film from dropping off due to multiple kinds of seepage and water condensation of a wall body, so that the paint film is more durable; in addition, the paint has no organic solvent, and is safe and environment friendly.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and relates to a polymer resin, in particular to a hydrophilic and lipophilic emulsion-type amphiphilic polymer resin and a preparation method thereof, and the invention also relates to the emulsion-type amphiphilic polymer resin Application in the production of intelligent breathing paint with humidity control function. technical background [0002] A safe and comfortable living environment has always been pursued by people, and indoor humidity is an important indicator affecting comfort. The humidity range that makes people feel better is 40% to 60%, too high or too low will affect human health. At present, indoor humidity control methods are divided into two types: active and passive. The former is mainly the air-conditioning technology commonly used at present. This method has problems such as large investment in equipment, high noise, high energy consumption, environmental pollution...
