Abstract

The invention discloses heat insulation outer wall putty powder and a preparation method thereof, and belongs to the technical field of building materials. Good bonding performance of dopamine is usedfor grafting; the inside structure of hardened putty powder is cured, so that the putty powder forms a hydrated gelling material with good cohesion and good flowing performance.Capric acid, lauric acid and the like are enabled to enter into a heat conduction passage to adsorb or release heat to achieve the heat balance for heat insulation; the heat insulation effect is improved; pores of the putty powder outer wall are charged; the compactness is improved. Polymethyl vinyl siloxane elastomers and introduced vinyl form the crosslinking; the dry-shrinkage cracking is reduced; the mechanical performance of the putty powder is improved. The relatively high light spreading speed is realized; the light can relatively fast transmit through the putty powder to realize photo-thermal conversion; the light effect and the heat storage and heat insulation performance of the outer wall can be further improved. The problem of poor heat insulation and thermal isolation effects of the existing outer wall putty powder can be solved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a heat-insulating exterior wall putty powder and a preparation method thereof. Background technique [0002] Putty powder is one of the most commonly used building decoration materials, and its main components are talcum powder and glue. Putty, to go a step further, is a kind of base material for leveling the wall, which lays a good foundation for future decoration (painting and wallpaper). 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 is not for internal use. Putties are usually based on gypsum or cement, so rough surfaces are easier to...
