Embodiment 1

[0050] (1) Preparation of soap-free emulsion type amphiphilic polymer resin

[0051] Formula: by weight

[0052] 15 parts of methacrylic acid, 60 parts of methyl methacrylate, 60 parts of butyl acrylate, 10 parts of hydroxypropyl methacrylate, 15 parts of diacetone acrylamide, 2 parts of potassium persulfate, 2 parts of sodium bicarbonate.

[0053] Process: uniformly mix 1 part by weight of methacrylic acid, methyl methacrylate, butyl acrylate, hydroxypropyl methacrylate, diacetone acrylamide and potassium persulfate to form a mixed monomer liquid; Dissolve 1 part of sodium hydrogen and remaining potassium persulfate in 160 parts of distilled water to form a transparent initiator solution, and heat up to 90°C; then add the above-mentioned premixed monomer liquid dropwise into the transparent initiator solution with a dropping funnel, and The dropwise addition is completed in 3 to 5 hours; then the temperature is lowered to 60° C., and ammonia water is added thereto to neutral...

Abstract

The invention provides a soap free latex type amphiphilic polymer resin, which is formed by polymerizing unsaturated acid alkyl, styrene, methyl methacrylate, butyl methacrylate, butyl acrylate, hydroxypropyl methacrylate, ethylene glycol methacrylate, acrylamide, diacetone-acryloamide and other monomers. The paint which takes the soap free latex type amphiphilic polymer resin as a main film forming material and combines with multiple kinds of 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 more 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 soap-free emulsion type amphiphilic polymer resin with hydrophilicity and lipophilicity and a preparation method thereof. The invention also relates to the soap-free emulsion type amphiphilic polymer resin. Application of pro-polymer resins in the production of smart breathing 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. "Heating Ventilation and Air Conditioning Design Specifications" GB50019-2003 stipulates that the standard value of indoor relative humidity is 40% to 60% for air-conditioned rooms in summer and 30% to 60% for heated rooms in winter, taking into account microbial growth, human disease, and item deterioration As well as vari...
