Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to anti-cracking exterior wall putty powder and a preparation method thereof.
Background
The putty powder is one kind of building decoration material, and has main components of talcum powder and glue, including inner wall and outer wall, and the outer wall putty has high glue performance, high strength and low environmental protection index. The putty is generally composed of base material, filler, water and assistant. The base material, also called adhesive, is the most key component of the putty and mainly plays various roles of adhesion and the like. The most common binders used in putties are cement and organic polymers, which are also classified as emulsions and emulsion powders. Cement is a good, durable and cost-effective binder, but has poor tensile strength and crack resistance. The organic polymer can modify and toughen the putty, thereby improving the performance of the putty. The filler mainly plays a filling role and is commonly used by calcium carbonate, talcum powder, quartz sand and the like. Attention should be paid to the use of the fineness of the filler. The auxiliary agent comprises a thickening agent, a water-retaining agent and the like. Thickeners and water retention agents act to retain water and improve storage and workability, and cellulose is generally used. The antifreezing agent is mainly used for improving the storage stability of the putty at low temperature, and the slip agent, the water reducing agent and the like are generally used in high-grade putty to improve the construction performance of the putty. And fiber is added into the fiber to play a role in cracking resistance. However, the conventional putty powder has low bonding strength and poor water resistance, and may not cause problems within one or two years, but the coating has the problems of cracking, peeling, mildew and the like after a long time. Therefore, the existing exterior wall putty powder formula and the preparation method thereof need to be improved to meet the use requirement.
