Cement-based multi-polymer dry mixed powder, preparation method and construction process thereof

Abstract

The invention provides cement-based multi-polymer dry mixed powder, a preparation method and a construction process thereof. The dry mixed powder comprises the following components in percentage by weight: 25 to 30 percent of No.42.5 cement, 20 to 25 percent of No.32.5 cement, 25 to 35 percent of triple superphosphate powder, 5 to 10 percent of gypsum powder, 1 to 3 percent of dispersible latex powder, 3 to 3.5 percent of starch ether, 1 to 3 percent of bentonite thixotropic lubricant, 1.5 to 2.0 percent of organic silicon, 0.15 to 0.20 percent of water repellent agent, 0.20 to 0.30 percent of methylcellulose and 0.30 to 0.60 percent of cellulose fiber. The preparation method for the dry mixed powder comprises the following steps: mixing the No.42.5 cement, No.32.5 cement, triple superphosphate powder, gypsum powder, dispersible latex powder, starch ether, bentonite thixotropic lubricant and organic silicon evenly according to the proportion, then adding a mixture of the water repellent agent, the methylcellulose and the cellulose fiber into the mixed substances, and stirring the mixture evenly to form the cement-based multi-polymer dry mixed powder. The construction process for the dry mixed powder comprises the following steps: mixing and stirring the dry mixed powder and sand evenly, adding proper amount of water into the mixture, and stirring the mixture to form a colloid substance.

Description

technical field [0001] The invention relates to an adhesive for construction, a preparation method and a construction process thereof, in particular to a powdered adhesive for indoor use instead of cement, a preparation method and a construction process thereof. Background technique [0002] When doing interior decoration of a house, it is necessary to use some kind of material with high bonding strength to paste decorative building materials such as wall or floor tiles on the foundation wall. Due to the low price of cement and high bonding strength, it is often used as a cement in the home decoration industry. It is widely used as an important bonding material. In general home decoration, most of them use cement mortar to paste wall and floor tiles, use cement mortar to build brick walls and structures, and use cement mortar to level the walls and floors. However, cement is a high energy consumption and high pollution product, and the country has many restrictions on the u...
