Abstract

The invention specifically relates to a novel efficient spraying heavy ground-floor plastering gypsum mortar, belonging to the technical field of building materials. The novel efficient spraying heavyground-floor plastering gypsum mortar comprises, by weight, 500-700 parts of flue gas desulfurization gypsum, 50-200 parts of ordinary Portland cement, 50-300 parts of heavy calcium carbonate powder,50-200 parts of talcum powder, 100-300 parts of quartz sand, 0.1-0.5 part of a retarder, 15-25 parts of redispersible latex powder, 3-5 parts of cellulose ether, 1-3 parts of wood fibers, 0.5-2.0 parts of starch ether, 1.0-3.0 parts of a thixotropic lubricant and 1 to 2 parts of polyacrylamide. The novel efficient spraying heavy ground-floor plastering gypsum mortar disclosed by the invention hashigh bonding strength, no phenomena of hollowing and cracking, good heat preservation effect, high coating rate and high construction efficiency.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel high-efficiency spraying heavy bottom plaster gypsum mortar. Background technique [0002] At present, most of the plastering materials for the inner walls of buildings in my country are cement-based plastering mortars, while more than 90% of the plastering materials in developed countries are gypsum-based plastering mortars. Cement-based plastering mortar has disadvantages such as poor bonding strength, easy hollowing, and cracking. Plastering gypsum mortar is a new, environmentally friendly and economical alternative to cement mortar. It not only has the strength of cement, but also is healthier and more environmentally friendly than cement. It is durable, has strong adhesion, is not easy to powder, does not crack, and does not hollow It has the advantages of no powder falling, easy to use, cost saving, and can well solve the shortcomings of poor bond streng...
