Anti-crack, noise-insulation and heat-preservation plastering material for inner wall

Abstract

An anticlastic, sound-proof, heat insulating inner wall plasterer material has new improvements in material and technological requirement aiming at present various light wallboards used in the inner wall of frame buildings, the present various light wallboards have the problems of wall surface crack, bad sound-proof effect and bad heat insulating effect. The material consists of two formulas; one is used in the bottom layer; the other is used in the surface layer. The bottom layer plasterer is formed by mixing high strength gypsum, water retention agent, ash-calcium-powder, plant fiber, expanded perlite, thickening agent, fly ash, poly-phenyl granule and retarding agent raw material according to certain weight portions; the surface layer plasterer is formed by mixing the high strength gypsum, the water retention agent, the ash-calcium-powder, the plant fiber, the expanded perlite, the retarding agent, medium sand and fine sand according to certain weight portions. By using and testing, the plasterer is obvious effect with smoothness without crack, good sound-proof and heat insulating effect and certain fire resistance performance.

Description

technical field [0001] The invention relates to building materials, in particular to wall plastering materials. Background technique [0002] With the reform requirements of building wall materials in recent years, the use of high-energy-consuming clay solid bricks has been banned. For interior walls, various types of lightweight wall panels have emerged, although they have played a role in replacing clay solid walls. Great energy-saving and area-enlarging effects, but due to unmatched material usage and craftsmanship, wall cracks, poor sound insulation and poor heat preservation are very common, and this is where users respond most strongly. [0003] The present invention proposes an improvement aiming at this present situation. Efforts are made on the material itself and the process method to make the whole plastering effect completely suitable for the technical requirements of the new type of wall. Firstly, it is smooth and not cracked; A big improvement. Contents of t...
