Problems solved by technology

[0004] Putty powder is difficult to distinguish good from bad with the naked eye. Some putty powders will turn white when touched soon after construction, and nails can be scratched. Its hardness, viscosity and construction performance are poor. Ordinary putty powders have poor thermal insulation effect. A kind of thermal insulation and flexible exterior wall putty can be developed

Abstract

The invention discloses flexible insulation exterior wall putty which is prepared from the raw materials, by mass, of 20-30 parts of deionized water, 40-54 parts of heavy calcium carbonate powder, 8-14 parts of aluminum powder, 8-12 parts of amino resin, 20-24 parts of pure acrylic emulsion, 5-9 parts of asbestos fiber, 2-5 parts of magnesium stearate, 1-3 parts of mannitol, 1-5 parts of dibutyl phthalate, 1-4 parts of sodium hexametaphosphate, 1-5 parts of carboxymethylcellulose, 2-4 parts of methyl 2-hydroxyethyl cellulose, 2-5 parts of bactericide and 3-6 parts of antifoaming agent. The prepared flexible insulation exterior wall putty is stable in quality, high in bonding strength, good in flexibility and constructability, low in heat conductivity coefficient, good in insulating effect and worth popularizing.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation flexible exterior wall putty and a preparation method. Background technique [0002] Putty powder is a decorative material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. Putty is applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. It is formulated with a small amount of paint base, additives, a large amount of fillers and an appropriate amount of coloring pigments. Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall i...
