Problems solved by technology

[0003] Although cement-based decorative materials have the above advantages, there are also some disadvantages, such as poor stain resistance and easy frosting on the surface, which affect their aesthetic and decorative effects
Moreover, when it is applied to the integrated system of building insulation and decoration, its setting time is relatively slow, which will also affect the factory production efficiency of the integrated system of building insulation and decoration.

Abstract

The invention belongs to the technical field of building material, and more specifically relates to a ternary cementitious system stucco finish, and an application method thereof. The ternary cementitious system stucco finish is composed of white Portland cement, sulphate aluminium cement, gypsum, superfine slag powder, zeolite powder, latex powder, cellulose ether, an air entraining agent, an antifoaming agent, a water repellent, a thixotropic agent, an inorganic pigment, an quartz sand. The ternary cementitious system stucco finish possesses excellent physical mechanical properties; setting time and operable time are controllable; development of early strength is rapid; strength is high; bonding strength with matrix is high; no shrinkage cracking is caused; durability is excellent; no crystalline bloom is caused; stain resistance is excellent; and decorative effect is excellent. The ternary cementitious system stucco finish is suitable for decoration engineering of building internal and external walls and building thermal-insulation decorative integrated systems; relatively mechanical strength is achieved in a relatively short term; construction efficiency is increased; performance of long-term application is excellent; and engineering quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a ternary gelling system facing mortar and a using method thereof. Background technique [0002] In recent years, with the development of green buildings, prefabricated buildings and building energy conservation in China, as a new building wall finishing material, cement-based finishing mortar has many advantages and characteristics, such as good air permeability and water permeability, easy to apply Construction, high adaptability to wall materials, high bonding strength, good durability, no aging problem, good decorative effect, color is not easy to fade, etc., has been used in the surface decoration of inner and outer walls of buildings. Cement-based finishing mortar is especially suitable for the surface decoration of the wall insulation system, which can significantly reduce the weight of the wall insulation system. Because it can achieve three-dimensi...
