Abstract

The invention discloses a modified-expanded-perlite insulation board and a production method therefor. The modified-expanded-perlite insulation board is prepared from the following ingredients in parts by weight: 18-25 parts of cement, 5-8 parts of fly ash, 2-5 parts of triethoxysilane, 5-10 parts of polyacrylate emulsion, 50-70 parts of modified expanded perlite, 0.7-2.9 parts of sodium dodecylbenzene sulfonate, 5-10 parts of additive, 0.1-0.5 part of PP fibers and 10-20 parts of water. According to the modified-expanded-perlite insulation board disclosed by the invention, the cement, the fly ash and other organic and inorganic matters serve as raw materials, so that wastes of industry and mining are put into effective use; and hazardous and noxious substances are not added, so that the modified-expanded-perlite insulation board is green and environment-friendly. The modified-expanded-perlite insulation board disclosed by the invention is wide in source of raw materials, low in cost, simple in production process and easy in operation, can meet the requirements of different building materials and has good social and economic benefits.

Description

technical field [0001] The invention relates to a modified expanded perlite insulation board and a production method thereof, belonging to the technical field of building materials. Background technique [0002] Building energy conservation is an industry supported by the national industrial policy. At present, building energy-saving materials are mainly divided into inorganic thermal insulation lightweight aggregates and organic thermal insulation lightweight aggregates. However, due to the characteristics of the chemical properties of materials, no matter whether it is an inorganic system or an organic system, it is impossible to meet the requirements of thermal insulation and energy saving performance and fire safety at the same time: from In terms of thermal insulation performance, organic materials are superior to inorganic materials; in terms of fire safety performance, Class A flame-retardant thermal insulation materials are the best choice. In recent years, expanded...
