Problems solved by technology

During the construction and installation of the above materials, a steel frame needs to be pre-set on the outer wall of the building, and then the wall panels are fixed on the steel frame. This installation method is complicated and costly, which increases the production cost of the developer and the construction unit.
On the other hand, the raw material for the production of polystyrene is a by-product of the petroleum processing industry. It can be seen that the production of polystyrene materials requires the use of precious petroleum resources in the country, and the production process will also cause pollution to the environment.
In summary, polystyrene thermal insulation materials have the disadvantages of easy aging, cracking, toxicity, and flammability, and

Abstract

The present invention relates to a heat insulation dry-mixing composition, a plastering method thereof and a board prepared by the composition. The heat insulation dry-mixing composition comprises the following components mixed according to a weight ratio: 15-2000 parts of hollow glass ball, 0.3-15 parts of short silk fiber, 5-200 parts of gypsum powder, 1-150 parts of emulsion powder, 0.3-150 parts of cellulose and 15-2000 parts of cement. The heat insulation dry-mixing composition of the invention has the advantages of low cost, excellent heat insulation effect, no aging, no cracking, no breaking-off and fire resistance. At the state of same thickness, the board prepared by the heat insulation dry-mixing composition according to the invention has better heat insulation effect compared with the heat insulation plate prepared by polystyrene material and perlite material. Furthermore the heat insulation dry-mixing composition and the board prepared by the composition can be directly adhibited and installed on the outer wall of building and have same lifetime with the building. The heat insulation dry-mixing composition is a novel product which gives attention to the convenient operation, low producing cost and environment-protecting energy-saving requirements.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, in particular to a thermal insulation dry mix composition, a plastering method and a board made of the composition. Background technique [0002] Thermal insulation panels are an indispensable material in the housing construction industry. According to national requirements, the external walls of buildings must be installed with thermal insulation panels. In the past, the thermal insulation materials commonly used in the construction industry contained polystyrene foam. For example, as disclosed in the Chinese patent titled "A Thermal Insulation Composite Wallboard" and the patent number is ZL200820087676.9, the insulation layer in the wallboard can be used Expandable polystyrene or extruded polystyrene. However, the polystyrene material itself is easy to age, crack and fall off, and the material contains the chemical component benzene, which itself has certain toxicity and ...
