Abstract

The invention discloses a preparation method of environment-friendly phase-changed insulated anti-cracking fast-setting spraying mortar. The preparation method comprises the following steps: mixing and stirring common silicate cement and sulfate aluminum cement into mixed cement; modifying expanded perlite by using polystyrene emulsion; adsorbing paraffin into a pore of the expanded perlite by using a reduced pressure adsorption method; coating by using cement; preparing silica-coated polyphenyl particles; preparing silica sol-modified aluminum oxide ceramic powder; uniformly mixing and stirring the prepared remaining blended cement, gypsum, aggregate coated with the blended cement, the silica-coated polyphenyl particles and the ceramic powder, continuously adding sepiolite fibers, polypropylene fibers and a thickening agent, and continuously performing uniform stirring and mixing to obtain the spraying mortar. The spraying mortar is good in thermal insulation, strong in adhesion strength and excellent in mechanical performance.

Description

[0001] Technical field: [0002] The invention relates to the field of building materials, in particular to a method for preparing green, environment-friendly, phase-change, thermal insulation, anti-cracking and fast-setting spray mortar. [0003] Background technique: [0004] The energy issue is a concern of all countries in the world today. As a building for human activities, the energy consumed during its use accounts for a large proportion of social energy consumption. At present, the energy consumption of buildings in developed countries in Europe and the United States has reached 30-50% of the total energy consumption of the whole society, and the total energy consumption of buildings in my country accounts for about 30% of the final energy consumption of the society. serious socio-economic problems. Reducing building energy consumption is one of the most important tasks in energy conservation work. Saving building energy is conducive to protecting energy resources, ens...
