Problems solved by technology

It not only occupies a large amount of arable land and pollutes the environment, but also produces harmful hydrogen sulfide gas when waste gypsum is mixed with organic matter
At present, the research and application of waste gypsum is mainly focused on adding it to cement as a retarder and as a roadbed material to reduce the environmental pollution caused by waste gypsum. a huge waste of resources

Abstract

The invention relates to a color decorative render and plaster for wall and a preparing method thereof. The color decorative render and plaster for wall is prepared from, by weight, 250-350 parts of reclaimed gypsum, 500-600 parts of quartz sand, 100 parts of coarse whiting, 5-10 parts of redispersible emulsion powder, 0.2-0.4 parts of cellulose ether, 4-10 parts of inorganic pigment, 2-4 parts of waterproof agent, 1.2-1.8 parts of retarder and 0.5-1 parts of water reducer; the redispersible emulsion powder is vinyl acetate / ethylene copolymer powder; the cellulose ether is hydroxypropyl methyl cellulose ether; the waterproof agent is the modified organosilicon waterproof agent; the water reducer is low alkali naphthalene superplasticizer; the retarder is sodium tripolyphosphate powder; which has the advantages of low cost, simple and convenient construction, long service time, good contamination resistance, crack resistance, weather resistance, alkali burnout resistance, and uniform and durable color.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a colored wall finishing mortar and a preparation method thereof. Background technique [0002] Finishing mortar refers to a kind of dry and screened aggregate (such as quartz sand), cementitious material (such as cement, etc.), additives (such as polymer, inorganic pigment), etc., which are mixed according to a certain proportion. Granular or powdery, transported to the construction site in bags or in bulk, and can be used directly after mixing with water. There are many colors of facing mortar, which are generally used on the surface of the wall as a wall decoration layer. It is suitable for the wall decoration of high-end real estate and villas and the decoration layer of personalized wall insulation systems such as entertainment venues and restaurants. [0003] Compared with conventional facing materials, facing mortar has the following advantages: ...
