Abstract

The invention relates to a kieselguhr composite heat insulation plate for an outer wall and a production process thereof, belonging to the field of building materials. In the invention, kieselguhr is used as a main material to prepare the kieselguhr composite heat insulation plate and a production process of the kieselguhr composite heat insulation plate is further provided. The composite heat insulation plate for the outer wall is prepared from the following raw materials: kieselguhr, polyvinyl chloride and processing auxiliaries. In the heat insulation plate for the outer wall, used kieselguhr has a series of good characteristics such as light weight, soft texture, multiple pores, sound insulation, heat resistance, acid resistance, stable chemical property and the like; and the producedkieselguhr composite heat insulation plate for the outer wall has the advantages of waterproofness, antiflaming property and low sound, heat and electricity conductivity, and is a new-generation fireproofing heat insulation plate for the outer wall.

Description

technical field [0001] The invention belongs to the field of building materials. Background technique [0002] At present, most of the materials used for external wall insulation are composed of two parts, the outer layer is benzene board, and the inner layer is foam, which is inconvenient to install, and the foam is extremely flammable, which has been an accomplice to many high-rise building fires. Contents of the invention [0003] The object of the present invention is to use diatomite as the main raw material to make diatomite composite exterior wall insulation board and its production process. [0004] The present invention makes the raw material weight portion of this insulating board and consists of: [0005] Diatomaceous earth 50~80 [0006] PVC 20~50 [0007] Processing aids 5-10. [0008] The diatomite in the present invention is activated diatomite with particle size above 600 mesh after winnowing. [0009] The polyvinyl chloride in the present invention is...
