Preparation method of coating type natural color sand flexible face brick and construction technology thereof

Abstract

The invention discloses a preparation method of coating type natural color sand flexible face brick and a construction technology thereof, which belong to the field of building material. The face brick is prepared by mixing the following constituents in percentage by weight: 12-16% of water, 0.1-0.2% of cellulose, 15-22% of emulsion, 20-25% of 41-80 mesh natural color sand, 40-50% of 81-120 mesh natural color sand, 2-5% of 21-40 mesh natural color sand, 0.08-0.12% of PH regulator, 0.02-0.06% of defoaming agent, 0.8-1.2% of antifreezing agent, 0.1-1% of thickening agent and 0.02-0.1% of preservative. The invention has the advantages of better flexibility, energy saving, environment protection, stain resistance and coating durability of above 15 years, and is suitable for heat insulation finish coat out of outer wall.

Description

[technical field] [0001] The invention relates to a material in the technical field of construction, in particular to a method for preparing a batch-coated flexible face brick made of natural colored sand and a construction process thereof. [Background technique] [0002] With the continuous development of the construction industry, especially the improvement of people's living standards, people's requirements for the living environment are becoming more and more stringent, and the requirements for thermal insulation and energy saving of buildings are also getting higher and higher. Safety, energy saving, heat preservation, comfort and beauty are the living environment that people pursue. Therefore, the external wall external insulation system is adopted for the external walls of public buildings and residential buildings. In order to ensure the safety of the external thermal insulation system, an higher requirement. Stone is mainly used for partial decoration of exterior d...

AI Technical Summary

Problems solved by technology

[0004] At present, it is common in the market to use real stone paint spraying as a brick-like finish layer, which solves the problem of replacing brick-like materials. On the one hand, the loss and waste of materials is relatively large, and there is still a big gap in the effect of spraying construction compared with facing bricks. The spraying effect is easy to hang dust and is not resistant to contamination. The batch coating process makes the overall surface smooth and less dust hanging, and the overall Good decorative effect and strong durability
