Abstract

The invention discloses a method for preparing assembled type building high-adhesive force polymer environmental-friendly spraying decoration mortar. The method comprises the following steps: uniformly mixing ordinary Portland cement, sulfate aluminum cement, quartz sand, calcium carbonate crystal whisker, an organic silicon coupling reagent, lignin fiber and basalt fiber, so as to obtain a mixed material A; uniformly mixing and stirring a silicon sol modified polyacrylic emulsion, cellulose ether, water and a thixotropic agent so as to obtain a mixed material B; and uniformly mixing the mixed material A and the mixed material B, thereby obtaining the high-adhesive force polymer environmental-friendly spraying decoration mortar. The spraying decoration mortar prepared by using the method is high in adhesive strength, good in weather resistance, excellent in mechanical property and environmental-friendly and non-toxic.

Description

[0001] Technical field: [0002] The invention relates to the field of building materials, in particular to a preparation method of high-adhesive polymer environmental protection spraying decorative mortar for prefabricated buildings. [0003] Background technique: [0004] In our country, as an extensive traditional residential construction method, there are many disadvantages, such as low production efficiency, poor engineering quality, many safety hazards, long construction period, low technological content in the construction industry, poor environmental protection benefits and high building energy consumption. question. Today’s popular housing industrialization construction method is the opposite intensive construction method, which prefabricates the building’s exterior walls, stairs, balcony panels and other components in the factory, and then transports them to the construction site to assemble and assemble the house. The construction of the building, the building produ...
