Abstract

The invention discloses a hydrophobic modified expanded perlite thermal insulation board and a production method thereof. The thermal insulation board comprises the following components, by weight: 20-30 parts of cement, 5-8 parts of fly ash, 2-5 parts of popyltrimethoxysilane, 5-10 parts of polyacrylate emulsion, 50-70 parts of modified expanded perlite, 0.7-2.9 parts of sodium dodecylbenzenesulfonate, 5-10 parts of additives, 1-3 parts of quicklime, 0.1-0.5 parts of PP fiber, 0.5-2 parts of hydroxypropyl methylcellulose, 5-10 parts of bentonite and 10-20 parts of water. According to the modified expanded perlite thermal insulation board, cement, fly ash, bentonite, PP fiber and other organics and inorganics are adopted as raw materials, such that industrial and mining waste materials are effectively utilized, and no toxic or harmful substance is added. Therefore, the modified expanded perlite thermal insulation board is green and environment-friendly. The modified expanded perlite thermal insulation board has the advantages of wide raw material source and low cost. The production process is simple and is easy to operate. With the thermal insulation board, requirements by different building materials can be satisfied, and good social and economic benefits are provided.

Description

technical field [0001] The invention relates to a water-repellent 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...
