Abstract

The invention discloses embossed texture decorative mortar which is dry-mixed mortar prepared by mechanically stirring cement, sand, auxiliary materials, emulsion powder, cellulose ether, an antimitotic agent, an expanding agent and other functional auxiliaries according to a certain proportion. The embossed texture decorative mortar prepared by the invention has the characteristics such as high strength after being hardened, good toughness, impact resistance, durability and roller coating property, elegant decorative effect, high texture and the like so as to be suitable for forming various three-dimensional concave-convex decorative effects.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to an embossed textured decorative mortar, a preparation method and a construction method thereof. Background technique [0002] Decorative mortar is a new type of building wall decoration material that has emerged in recent years. It is composed of inorganic cementitious materials, fillers, aggregates and various additives, and can be widely used in the decoration of building wall surfaces. Compared with facing bricks, decorative panels and other materials, decorative mortar has the advantages of light weight, low cost and convenient construction. When used as a high-rise building decoration, bricks will not fall due to negative wind pressure, thereby ensuring the safety of the external wall insulation system. Reliable; compared with exterior wall coatings, it has good durability, which can reduce the cost of maintenance and renovation of organic coating products; and the ...
