Indoor gypsum plaster and preparation method thereof

Abstract

The invention discloses indoor gypsum plaster and a preparation method thereof. The gypsum plaster comprises, by weight, 40-50 parts of hemihydrate gypsum cementing material, 10-16 parts of diatom ooze, 5-8 parts of calcium powder, 40-60 parts of talcum powder, 0.05-0.10 part of methyl cellulose, 0.4-0.8 part of calcium sulfate, 1.5-3.5 parts of nano titanium dioxide particle, 2.5-6.5 parts of nano silicon dioxide particle, 0.05-0.06 part of retarder, 2.5-4.5 parts of dispersible latex powder, 1.5-2 parts of sodium hydrogen sulfate, 3-10 parts of graphene and 0.5-1.2 parts of auxiliary materials. The indoor gypsum plaster has the advantages that the performance such as the compressive strength, the fracture strength, the water retaining rate and the bonding strength of the gypsum plaster is increased by adding the graphene, the service life of the gypsum plaster is prolonged, and the use stability of the gypsum plaster is increased.

Description

technical field [0001] The invention belongs to the field of decoration materials, and in particular relates to an indoor plaster for plastering and a preparation method thereof. Background technique [0002] In recent years, with the intensified promotion of the "four new technologies" in the construction field, many new materials have been applied, which has promoted the improvement of project quality. For areas with dry climate and large temperature difference between day and night, plastering with cement mortar cannot fundamentally solve the common quality problems of plastering voids caused by cement shrinkage, especially on concrete surfaces, ceramsite and aerated concrete masonry plastering voids protrude. [0003] With the improvement of people's living standards, the improvement of living conditions and living environment is one of the important signs. People not only require spacious living, but also require a higher quality of living and a more comfortable livin...

AI Technical Summary

Problems solved by technology

For example, the practice of using traditional cement mortar and mixed mortar for wall plastering materials is far from being able to meet the needs. These traditional plastering materials have many disadvantages such as easy cracking, hollowing, more ground dust, and poor bonding performance.

Secondly, due to the slow setting and hardening, especially in the case of low winter temperatures, the time interval between the plastering process and the final decoration process is half a month or even longer, which has become the biggest obstacle restricting rapid construction.
