Environment-friendly external wall thermal-insulation putty and preparation method thereof

Abstract

The invention relates to an environment-friendly external wall thermal-insulation putty. The putty is prepared by adding paper making white clay slag, steel slag and pure calcium aluminate cement on the basis of the conventional formula, and thus, belongs to a pure inorganic material. The putty has the characteristics of environment friendliness, no toxicity or odor, light weight, higher strength, lower heat conductivity coefficient and the like, and thus, has the advantages of thermal-insulation property, light dead weight, flame retardancy, sound insulation, weather resistance, aging resistance, freeze-thaw resistance, moisture resistance, seepage resistance, stable performance, excellent operating performance, convenient construction, low manufacturing cost and the like, thereby satisfying the determination of the design or construction technical scheme. The putty is suitable for internal / external wall thermal-insulation engineering in the regions with hot summer and cold winter, regions with hot summer and warm winter and part of cold regions, is also suitable for thermal insulation for party walls, floors, channels, basements, floor heating and other positions of the buildings, and can achieve the energy-saving effect. The putty can also be used for energy-saving reconstruction of the existing buildings.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environment-friendly exterior wall thermal insulation putty and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, the plastering project, as an important part of the construction, is more and more valued by this industry. Plastering can protect walls and improve indoor sanitation conditions, enhance light reflection, beautify the environment, and also protect walls, ceilings, roofs and other parts from erosion by wind, rain, and snow, and improve the moisture resistance, weather resistance, and heat insulation of walls. The ability to enhance the durability of the wall. However, the traditional painting materials such as cement mortar and mixed mortar cannot adapt to the surface painting of new wall materials such as blocks and plates, and there will be phenomena such as hollowing, cracking and fa...

AI Technical Summary

Problems solved by technology

But the construction cost of the stucco material is still high

At present, the products on the market still have phenomena such as hollowing, cracking, and falling off in an environment with high humidity. Therefore, the market needs an environmentally friendly exterior wall thermal insulation putty to replace the existing process, so as to reduce costs and improve work efficiency.
