Abstract

The invention discloses a lightweight heat insulation sheet material containing expanded perlite and silica sand and a preparation method thereof. The heat insulation sheet material is prepared form the following components in parts by weight: 50 to 60 parts of the expanded perlite, 2 to 5 parts of talcum powder, 20 to 30 parts of the silica sand, 0.2 to 0.7 part of a moisturizing agent and 30 to 40 parts of sodium silicate. The preparation method of the heat insulation sheet material comprises the following steps: (a) uniformly stirring the raw materials at room temperature according to the weight ratio; (b) putting a mixture in step (a) into a mold and carrying out compression molding on the mixture by adopting a pressing machine to prepare a semi-pore sheet material; (c) drying the sheet material formed by the compression molding at 150 DEG C to 180 DEG C. A steel wire net is arranged at the middle part of the heat insulation sheet material. The perforation percentage of the heat insulation sheet material is 10 percent to 18 percent. According to the sheet material disclosed by the invention, a preparation process is simple and the sheet material is incombustible, has heat insulation and fireproof effects and is convenient to mount and replace; the sheet material can be suitable for an external wall and an internal wall of a common building and is also suitable for heat insulation and fire prevention of high-rise buildings.

Description

technical field [0001] The invention relates to a fire-proof, heat-preserving, environment-friendly and energy-saving material and a preparation method thereof, in particular to a heat-preservation board containing expanded perlite and silica sand and a preparation method thereof. Background technique [0002] Adopting good fireproofing and thermal insulation technology and materials in construction and industry can often get twice the result with half the effort. The use of good heat insulation measures and materials can significantly reduce production energy consumption and costs, improve the environment, and at the same time have better economic benefits. The current insulation of building walls mainly includes external insulation, internal insulation, self-insulation, and sandwich insulation. This type of insulation usually uses various insulation materials to achieve the purpose. The materials currently used mainly include molded boards and extruded boards. burning pro...
