Problems solved by technology

Pasting ceramic tiles on the surface of the external thermal insulation thin plastering system, especially the external thermal insulation of high-rise buildings, has higher safety requirements. Because the external thermal insulation system of external walls is different from the base layer of heavy walls, external thermal insulation The built-in density of the layer is small and the strength is low. The composite wall formed by the external thermal insulation system often presents the characteristics of a soft base layer. Materials such as ceramic tiles and mosaics on the facing layer are rigid materials. The bonding strength of the plastering layer is different from that of ceramic tiles, and the load of ceramic tiles pasted on the insulation layer is too large (25kg / m 2 -40kg / m 2 ) and other reasons, ceramic tiles are pasted on the thermal insulation surface of the outer wall of the expanded polystyrene board with thin plaster. Due to the above reasons, quality accidents such as tile detachment continue to increase, and the buildings that cost a lot of money to decorate become beyond recognition. It also increases the difficulty of the project, which not only affects the aesthetics of the building environment, but also seriously threatens the safety of people's personal and property, and there are serious hidden dangers

Abstract

The invention relates to a thermal insulation textured decorative face brick for a building outside wall. The face brick comprises the following raw materials in parts by weight: 25-35 parts of cement, 20-35 parts of quartz sand, 10-15 parts of calcite powder, 10-20 parts of wollastonite powder, 2.0-4.0 parts of latex powder, 0.3-0.4 part of hydroxypropyl cellulose, 0.5-1.0 part of wood fiber, 0.15-0.2 part of short polypropylene fiber, 0.2-0.5 part of calcium formate, 10-20 parts of gray calcium powder, 0.1-0.15 part of thixotropic lubricating agent and 0.25-0.5 part of pigment. After being put on the market, the face brick has great market space, and the current monotonous situation of outside wall exterior thermal insulation textured decorative materials can be improved, thus the face brick has active effects on saving energy of buildings and beautifying the environment of cities.

Description

technical field [0001] The invention belongs to a building energy-saving external wall thermal insulation facing color texture decorative facing brick and a construction process thereof. Background technique [0002] With the continuous advancement and development of building energy-saving external wall insulation projects in my country, the Chinese government has made energy conservation and emission reduction a basic national policy, and building energy-saving external wall insulation has been listed as a mandatory standard. In our province's building energy-saving exterior wall insulation projects, accounting for 80% of the project, the expanded polystyrene board exterior wall insulation thin plastering system is used. Pasting ceramic tiles on the surface of the external thermal insulation thin plastering system, especially the external thermal insulation of high-rise buildings, has higher safety requirements. Because the external thermal insulation system of external wal...
