Abstract

The invention discloses putty leveling integrated gypsum mortar. The mortar is formed by mixing and stirring, by weight, 60-70 parts of desulfurized gypsum, 10-15 parts of 250-mesh heavy calcium carbonate, 6-10 parts of quartz sand of 20-30 meshes, 10-15 parts of 40-mesh quartz sand, 2-5 parts of glass bead heat preservation lightweight aggregate, 1-2 parts of redispersible emulsion powder VAE, 0.2-0.5 part of hydroxyethyl methylcellulose ether and 0.03-0.05 part of modified protein retarder. By means of the putty leveling integrated gypsum mortar, the traditional indoor leveling construction is greatly simplified, multiple construction procedures such as existing adhesion agents, leveling mortar and putty are replaced, forming can be completed at a time, the maintenance period is short, the construction period is greatly shortened, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to building mortar materials for leveling indoor walls, in particular to a gypsum mortar product which is modified by a polymer and integrates the functions of interface treatment, wall leveling and putty embedding. Background technique [0002] In order to improve the living environment and comfort requirements, secondary decoration is becoming more and more common in the home improvement market and has broad market prospects. The steps are as simple as possible, the maintenance period is short, and the precious construction time will not be taken up. Therefore, it is urgent to develop a gypsum mortar integrating multiple functions such as leveling and batch embedding. [0003] Desulfurization gypsum is an industrial by-product gypsum obtained by desulfurizing and purifying the flue gas generated after the combustion of sulfur-containing fuels (mainly coal). Every year, nearly 100 million tons of desulfurization gypsum, a by-pr...
