Problems solved by technology

In my country, the use of architectural coatings to decorate the exterior walls of buildings has become more and more widespread. However, there is a serious quality problem that the coating film cracks along with the cracks in the wall, which gradually destroys the overall decorative effect of the building. Many buildings After a period of use, the paint surface of the object will appear peeling and falling off, which will eventually lead to cracking and leakage of the wall

Abstract

The invention discloses a waterproof flexible material for an external insulating wall space. The material is prepared from the following raw materials in parts by weight: 235-245 parts of silicate cement, 568-570 parts of sand, 14-152 parts of ground calcium carbonate powder, 18-22 parts of redispersible rubber powder 5044N, 14.5-15.5 parts of redispersible rubber powder 8034H, 1.8-2.2 parts of cellulose ether, 2.7-3.4 parts of wood fibers and 0.8-1.2 parts of an organosilicone water repellent. The waterproof flexible material for the external insulating wall space disclosed by the invention not only has extremely high water resistance and caking property, but also has the advantages of high-low temperature change resistance, crack resistance and the like, solves the problem that existing external wall putty powder is relatively poor in weather resistance, is free of phenomena of hollowing, peeling, cracking and falling if encountering with water and being moisturized, is extremely high in waterproofness, green and environment-friendly, good in flexibility, difficult to pulverize, is fine and smooth in surface texture if being scraped, and is safe and environment-friendly and long in service life.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof flexible material for external thermal insulation walls. Background technique [0002] Putty material is a supporting product for base treatment when building fillers are painted. Putty materials are generally composed of base materials, fillers, water and additives. The base material, also known as the binder, is the most important component of the putty material, and it mainly plays various functions such as bonding. The filler mainly acts as a filling, and the commonly used ones are calcium oxide, talcum powder and quartz sand. Additives include thickeners, water retaining agents, preservatives, etc. Thickeners and water-retaining agents play the role of water retention, improving storage and construction, and cellulose is generally used. Preservatives are mainly used to prevent deterioration due to corruption during storage. In addition, there are...
