Gypsum substrate render material

Abstract

The gypsum-based whitewash material consists of beta-gypsum with beta-CaSO4.1 / 2H2O as main component 99-99.9 wt% and anhydrous citric acid or its salt as coagulation regulator 0.1-1 wt%. The presentinvention has strong adhering capacity, and can inhibit the shrinkage and cracking in whitewashing. It has excellent surface decoration performance, fireproof performance and heat insulating performance. It has simple production process, low production cost and light weight.

Description

technical field [0001] The invention relates to a building plastering material, in particular to a building plastering gypsum. Background technique [0002] At present, in the construction industry, the country has banned the use of clay solid bricks, and instead use new wall materials such as blocks and plates. The original painting materials such as cement mortar and mixed mortar cannot adapt to the surface painting of the above-mentioned new wall materials, and there will be hollowing, cracking, falling off and other phenomena, which will affect the building quality. But up to the present, also do not have a kind of ideal and applicable building plastering material with novel wall material. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and propose a gypsum-based plastering material with strong cohesive force, convenient construction and guaranteed building quality. [0004] Technical solution for the purpose of ...
