Interior wall flexible render gypsum

Abstract

The present invention discloses a soft stucco gypsum for inner wall, which is characterized in that: the molar percent of the material component is that: 50 -80 percent of alkaline fluor gypsum, 20 - 40 percent of ash calcium; 0.1- 1 percent of methyl hydroxide ethylic cellulose; 1 - 5 percent of acetic acid ethylene- carbonic acid ethylene ester. The material has the advantages of smooth and easy to be stucco with moderate felting ability and concreting speed; the surface is hard not easy to craze with high soft intension and waterproof ability. The material does not need retreated before making the wall construction again.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flexible plastering gypsum for interior walls. Background technique [0002] The production capacity of my country's AHF industry ranks first in the world, with a production capacity of about 800,000 tons / year. The waste residue fluorogypsum produced in the production is about 3 million tons / year, which is harmful to the environment. At present, the development of comprehensive utilization of waste slag is unbalanced. The utilization in the eastern region is mainly used as an auxiliary material in the cement industry, which is a low value-added utilization; due to the abundant cement resources in the western region, fluorine gypsum waste slag has not been utilized. In recent years, the building materials industry has developed rapidly, but it consumes a lot of resources, and many industrial wastes have not been comprehensively utilized. Utilizing fluorogypsum modifi...
