Problems solved by technology

[0002] Gypsum plastering mortar is widely used in building interior walls because of its good working performance, small shrinkage, not easy to crack, good moisture drainage and hygroscopicity, and the function of regulating indoor humidity. The plastering gypsum mortar currently on the market In the process of use, it is difficult to meet the performance of mechanical spraying, and the traditional machine-sprayed plaster mortar has poor moisture absorption and dehumidification effects, and cannot be well sound-proof and noise-reducing, and some machine-sprayed plaster mortars still have unpleasant smell Non-toxic odor, can not be accepted by the majority of users, so it is not easy to promote and use, so it is not suitable for the use of building interior walls. Uneven mixing of lime gypsum mortar will lead to uneven mixing of raw materials, resulting in cracking, hollowing and anti-alkali conditions, which will cause machine spray plastering gypsum mortar to fail to achieve the desired effect

Abstract

The invention discloses a machine-spraying plastering gypsum mortar and a preparation process thereof, and relates to the field of building materials. The machine-spraying plastering gypsum mortar is prepared from the following raw materials by weight: 80-90 parts of gypsum, 2-4 parts of heavy calcium powder, 11-13 parts of cement, 100-120 parts of river sand, 0.08-0.12 part of a thixotropic agent, 0.1-0.14 part of a protein retarder, 3-5 parts of diatomite powder, 8-12 parts of a chemical additive and 80-90 parts of clear water. According to the machine-spraying plastering gypsum mortar and the preparation process thereof, compared with traditional machine-spraying plastering gypsum mortar, the diatomite powder is added, the diatomite powder has a powerful breathing and humidity adjusting function, and when the diatomite powder is mixed into the machine-spraying plastering gypsum mortar, the machine-spraying plastering gypsum mortar has the functions of moisture absorption and moisture removal, and indoor humidity can be effectively adjusted, and the diatomite powder also has the effects of purifying air and can achieve good flame-retardant, sound-insulating and noise-removing effects, so that the diatomite powder can be accepted by vast consumers, and is convenient to popularize and use.
