Problems solved by technology

Traditional exterior wall putty usually consists of putty powder, construction glue and clear water. Professional workers at the construction site perform mechanical or manual mixing before it can be applied to the base layer of the wall. However, due to the uneven amount of water added by manual mixing, it may cause the Putty paste applied to the same wall has different adhesion to the wall, which will lead to poor crack resistance of the outer wall, and this prepared putty paste has no thermal insulation effect

Abstract

The invention provides putty paste used for a building exterior wall and a preparation method thereof. The putty paste is prepared from white cement, salt gypsum powder, ash-calcium powder, rubber powder, an elastic polypropylene emulsion, a leveling agent, a shrinkage compensating agent, an insulating agent, ionized water and additive according to the weight ratio. When the putty paste is prepared, the conventional materials are added, the insulating agent and the additive prepared in the special method are added, and the crack resistance and the heat preservation property of the putty paste are improved.

Description

technical field [0001] The invention relates to a putty paste used in the field of architectural decoration, in particular to a putty paste for building exterior walls and a preparation method thereof. Background technique [0002] Putty paste is a kind of building decoration material. It is a base material used for wall repair and leveling, which lays a good foundation for the next step of decoration (painting and wallpaper). Traditional exterior wall putty usually consists of putty powder, construction glue and clear water. Professional workers at the construction site perform mechanical or manual mixing before it can be applied to the base layer of the wall. However, due to the uneven amount of water added by manual mixing, it may cause the High-quality putty paste applied to the same wall has different adhesion to the wall surface, which will lead to poor crack resistance of the outer wall surface, and this prepared putty paste has no thermal insulation effect. [0003]...
