Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a light-weight plastering gypsum mortar and a preparation method thereof, which solves the problem that the existing light-weight plastering gypsum mortar has poor bonding strength and is easily affected by humidity, especially during the rainy season. There will be quality problems such as hollowing, cracking and dusting on the surface, which will affect the life and normal use of the building. In serious cases, it will easily fall off in a large area and reduce the performance

Embodiment example 1

[0035] See Figure 1-7 The present invention provides a technical solution: a method of preparing a light plaster plaster mortar, composed of the following steps:

[0036] Step 1, preparation plaster powder: Treatment of gypsum to get a metallic plaster powder with uniform fineness;

[0037] Step 2, a starch ether: is prepared by potato starch, cassava starch, corn starch, wheat starch, etc., and passes through the copper salt as a catalyst, and the starch ether is obtained by means of a reaction kettle and ultrasonic waves to obtain a starch ether;

[0038] Step three, prepare a raw material mixture: step one in the plaster powder, step two of the starch ether, cement, fly ash, water storage agent in the mixing device, and mix;

[0039] Step 4, prepare plasterite: completely mix the mixing and collectivity in step three, get plaster plaster, make the gypsum mortar thickens, while reducing the influence of moisture weather, it is not easy to have empty drums, cracking, The surface ...

Abstract

The invention discloses lightweight plastering gypsum mortar and a preparation method thereof. The preparation method comprises the following steps of preparing gypsum powder: grinding gypsum to obtain gypsum powder with uniform fineness; preparing starch ether: carrying out a silicon etherification reaction on starch serving as a raw material with a copper salt as a catalyst by means of a reaction kettle and ultrasonic waves to obtain the starch ether; preparing a raw material mixture: pouring the gypsum powder, the starch ether, cement, fly ash and a water-retaining agent into a mixing device, and uniformly mixing; and preparing plastering gypsum: fully mixing the mixture obtained in the third step and aggregate again to obtain the plastering gypsum. According to the lightweight plastering gypsum mortar and the preparation method thereof, the effect of improving the comprehensive capacity is achieved, the thickening capacity is good, meanwhile the influence of humid weather is reduced, the quality problems of hollowing, cracking, surface dusting or falling are not prone to occurring, the service life of a building is prolonged, and the use performance is improved.

Description

Technical field [0001] The present invention relates to the technical field of building materials, in particular a light plaster plaster mortar and a preparation method thereof. Background technique [0002] With the continuous development of science and technology, the continuous advancement of society, the construction industry is also quietly developed. With the in-depth advancement of national energy-saving and environmental protection policies, industrial by-product plaster represented by calcination dethylsulfide is used as the main raw material to prepare semi-water plaster plaster, and widely developed. Plasterite is a green environmental protection material that adapts to the new wall indoor plaster. Plastering plaster is its good supporting material, which ensures that the plaster layer is not empty, not cracking. The gypsum paste is easily penetrated into the pores of the wall panel, and the volume expansion in the hydration process constitutes the 楗 楗 and the fine sea...
