Wall adhesive powder

Abstract

The wall adhesive powder consists of cement 100 weight portions, dry sand 50 weight portions, fly ash 30-35 weight portions, lime 40-50 weight portions, hydroxypropyl methyl cellulose ether 1-2 weight portions, wood fiber 3-4 weight portions, redispersive gelatin powder 6-8 weight portions, air entraining agent 0.06-0.08 weight portions, and PP fiber 0.2-0.3 weight portions. The wall adhesive powder for building has the advantages of firm adhering, high pressure strength, high tensile strength, excellent antiseepage performance, anticracking, low cost, etc.

Description

technical field [0001] The invention relates to a building material, in particular to a bonding rubber powder for walls. Background technique [0002] At present, the residential area of ​​our country has increased from 40 billion m 2 , Building energy consumption accounts for 30% of the total energy consumption of the society, only a few tenths of percent of old-fashioned residential buildings meet energy-saving standards, and only 15% of new-built residential buildings meet energy-saving standards. With the rapid development of marketization of commercial housing, people's living conditions have been greatly improved. The requirements for housing have developed from the pursuit of area to the pursuit of quality. Designs to improve energy efficiency, improve indoor environment, building facilities and high-performance housing have become the most recent and The focus of future development, in developed countries in Europe and America, wall insulation measures have become a...

AI Technical Summary

Problems solved by technology

New thermal insulation materials such as expanded perlite, EPS-expanded polystyrene board, XPS-extruded polystyrene board, GS-closed-cell foam glass board, Fine-external wall decoration insulation board, etc. There are a large number of domestic manufacturers producing the aforementioned products, but If these products are to be firmly bonded to the wall, it is also necessary to ensure that these insulation materials can withstand the erosion of the external natural environment. Temperature changes, cold radiation, heat radiation, wind and rain, blowing, etc. will cause damage to the insulation materials, so , it is necessary to have a bonding material with firm bonding, tensile resistance, compression resistance, crack resistance, etc.

[0003] At present, most of them use cement mortar as the bonding material, but the use shows that there are defects in the crack resistance, tensile strength, compression resistance and anti-seepage performance of cement. Due to poor adhesion, in order to enhance the bonding effect, it is necessary to increase the amount of use. , but this will increase the load of the wall and insulation materials, which not only increases the cost and construction troubles, but also the insulation materials are easy to fall off, posing safety hazards, hollowing, water seepage, and cracking will occur after a long time, and the insulation and energy saving requirements cannot be guaranteed.
