Embodiment Construction

[0007] The present invention adopts such a technical scheme: the materials and weight proportions in the heat-insulating exterior wall coating are respectively: 28 parts of water, 1.1 parts of dispersant, 0.51 parts of wetting agent, 2.3 parts of ethylene glycol, film-forming assistant 1.2 parts of agent, nano Al 2 o 3 1.4 parts, 19 parts of rutile titanium dioxide, 20.3 parts of talcum powder, 15 parts of modifier, 12.1 parts of light calcium carbonate, 0.6 parts of defoamer, and 3.8 parts of thickener.

[0008] Its preparation method is the following steps:

[0009] Step 1), add water, dispersant, wetting agent, ethylene glycol, film-forming aids, nano-Al 2 o 3 , rutile titanium dioxide, talcum powder, modifier, light calcium carbonate, defoamer, thickener, fully mixed and stirred evenly for later use;

[0010] Step 2), the material obtained in step 1) is left to stand in the reactor for 40 hours, filtered and canned to obtain the finished product.

Abstract

The invention relates to heat insulation and heat preservation exterior wall paint and a preparing method. The heat insulation and heat preservation exterior wall paint is prepared from, by weight, 28 parts of water, 1.1 parts of dispersant, 0.51 part of humectant, 2.3 parts of ethylene glycol, 1.2 parts of coalescing agents, 1.4 parts of nanometer Al2O3, 19 parts of rutile titanium dioxide, 20.3 parts of talcum powder, 15 parts of modifier, 12.1 parts of light calcium carbonate, 0.6 part of defoamer and 3.8 parts of thickener. The heat insulation and heat preservation exterior wall paint can be used for painting exterior walls of buildings such as residences, hotels, schools, institutions, dormitories and apartments, has the advantages of being simple for construction, waterproof, free of pollution, toxins and smells, good in heat insulation effect and the like, and has the advantages of being high in adhesive force, good in heat preservation and heat insulation, high in stain resistance, resistant to scrubbing, waterproof, high in corrosion resistance and whether resistance, long in service life and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an architectural coating, which can be used as a heat-insulating and thermal-insulating exterior wall coating for exterior walls of houses, hotels, schools, offices, dormitories, apartments, etc., and has the advantages of simple construction, waterproof, pollution-free, It has the advantages of strong adhesion, good thermal insulation, high stain resistance, scrub resistance, cold resistance, water resistance, strong corrosion resistance, strong weather resistance, and long service life. Background technique [0002] The coating that can play the role of thermal insulation on the surface to be constructed is called thermal insulation coating, which can be divided into transparent thermal insulation coating and non-transparent thermal insulation coating according to different application occasions; Thermal insulation coatings are divided into three categories: barrier thermal insulation c...
