preparation example Construction

[0062] A kind of preparation method of gypsum base wall leveling material of the present invention, comprises the following steps:

[0063] Mix hemihydrate gypsum, fly ash, admixture, calcium hydroxide, zeolite, water retaining agent and retarder, and stir evenly;

[0064] The mass portion of the hemihydrate gypsum is 55-70 parts; the mass portion of the fly ash is 8-20 parts; the mass portion of the admixture is 4-8 parts; the calcium hydroxide The mass parts of the zeolite are 4-8 parts; the mass parts of the zeolite are 3-6 parts; the mass parts of the water-retaining agent are 0.2-0.5 parts; the mass parts of the retarder are 0.05- 0.1 copies;

[0065] The admixture is selected from one or both of silica fume and metakaolin.

[0066] It can be understood that the raw materials can be mixed in a dry powder mixer, and the formula raw materials are added to the dry powder mixer in sequence, and stirred evenly to obtain a gypsum-based wall leveling material.

Abstract

The invention relates to a gypsum-based wall leveling material as well as a preparation method and a use method thereof. The wall leveling material is prepared from the following raw materials in parts by mass: 55-70 parts of semi-hydrated gypsum; 8-20 parts of fly ash; 4-8 parts of an admixture; 4-8 parts of calcium hydroxide; 3-6 parts of zeolite; 0.2-0.5 part of a water retaining agent; and 0.05-0.1 part of a retarder; wherein the admixture is selected from one or two of silica fume or metakaolin. The gypsum-based wall leveling material provided by the invention does not need cement, redispersible rubber powder and a water repellent, can also have good water resistance, can maintain good mechanical properties in a high-humidity environment, can also solve the problems of hollowing and cracking of a wall surface, and is low in cost and easier to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a gypsum-based wall leveling material and a preparation method and application method thereof. Background technique [0002] At present, wall leveling materials in this field are mainly cement-based mortars. However, cement is a rigid material, brittle in nature, and the shrinkage rate of cement plastering mortar is large (about 0.3%), which leads to the hollowing and cracking of the plastering layer of the new building wall, which is currently the first problem affecting the quality of the construction industry. ill. With the increase of well-decorated houses and the higher requirements of customers for product quality, there is an urgent need for an effective solution that can solve the hollowing and cracking of the plaster layer of the building wall. Most of the existing research is on cement-based mortars. The idea is to add redispersible rubber powder...
