Problems solved by technology

This thickness will greatly increase the load-bearing capacity of the wall and increase the load capacity of the building.
Moreover, the wall is inorganic, and the cement polyphenylene mortar is organic. The inorganic and organic materials cannot be combined well. Once it falls off, it will cause casualties and pose a great safety hazard.

Abstract

The invention discloses an inner and outer wall thermal insulation paste material, a preparation method and the application thereof. The inner and outer wall thermal insulation paste material is mainly composed of the following components by the parts by weight: 20 to 40 parts of expanded perlite, 5 to 10 parts of polystyrene particles, 70 to 130 parts of powder and 0.8 to 2 parts of additive. The inner and outer wall thermal insulation paste material has strong thermal insulation performance (the thermal conductivity coefficient is 0.045 to 0.055w / m.k), small volume, high strength (compressive strength is 0.6 to 1.0MPs), strong hydrophobic property, high anti-carbonation property, strong anti-freezing expansion ability and long service life.

Description

technical field [0001] The invention relates to a building material, in particular to a building inner and outer wall thermal insulation slurry material and a preparation method thereof, belonging to the field of building materials. Background technique [0002] At present, the thermal insulation mortar used for external wall thermal insulation in the thermal insulation market is composed of cement mixed with polystyrene particles. This thermal insulation material has technically insurmountable defects and unsatisfactory parts. [0003] The thermal insulation mortar currently on the market is only made of cement plus polystyrene particles plus heavy calcium powder and binder. The thermal conductivity of cement is as high as 1-2w / m·k, and the polyphenylene particles with a thermal conductivity of 0.042-0.043w / m·k are wrapped, and the thermal conductivity of the formed cement polyphenylene mortar is 0.095-0.098w / m·k. According to the test results of the Shanghai Construction ...
