Abstract

The invention discloses a cement-based modified expanded perlite insulation board and a production method thereof. The insulation board comprises the following components in parts by weight: 25 to 40 parts of cement, 5 to 8 parts of fly ash, 2 to 5 parts of methyltrimethoxysilane, 5 to 10 parts of a polyacrylate emulsion, 50 to 70 parts of modified expanded perlite, 0.7 to 2.9 parts of sodium dodecyl benzene sulfonate, 5 to 10 parts of an additive, 1 to 3 parts of water glass, 0.1 to 0.5 part of PP fiber, 0.5 to 2 parts of hydroxypropyl methyl cellulose, 3 to 5 parts of zirconia fiber and 10 to 20 parts of water. The modified expanded perlite insulation board provided by the invention uses cement, fly ash, PP fiber and organic and inorganic matters as raw materials, so industrial and mineral waste materials are effectively utilized; meanwhile, no toxic and harmful substance is added, so greenness and environmental protection are achieved. The modified expanded perlite insulation board provided by the invention has the advantages of extensively available raw materials, low cost, simple production process, facilitation to operation, capability of meeting the demands of different building materials, and good social and economic benefits.

Description

technical field [0001] The invention relates to a cement-based 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 ye...
