Abstract

The invention discloses a mineral fiber enhanced modified expanded perlite insulation board and a production method thereof. The mineral fiber enhanced modified expanded perlite insulation board comprises in parts by weight, 25-40 parts of cement, 5-8 parts of coal ash, 2-5 parts of methyltrimethoxysilane, 5-10 parts of polyacrylate emulsion, 3-5 parts of mineral fibers, 50-70 parts of modified expanded perlite, 0.7-2.9 parts of sodium dodecyl benzene sulfonate, 5-10 parts of additives, 1-3 parts of calcined lime, 0.1-0.5 part of PP (polypropylene) fibers, 1-2 parts of sodium silicate and 10-20 parts of water. The mineral fiber enhanced modified expanded perlite insulation board takes the cement, the coal ash, the mineral fibers and other organic and inorganic matters as raw materials, industrial and mining waste materials are effectively used, toxic and harmful substances are not added, and the insulation board is green and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mineral fiber-reinforced modified expanded perlite insulation board and a production method thereof. Background technique: [0002] With the vigorous development of the construction industry and the modernization of buildings, the use of insulation boards in construction projects has increased year by year. External wall insulation can effectively block heat conduction, and the insulation effect is very obvious. It can not only save a lot of heating costs in winter, but also is more environmentally friendly than other heating methods. The thermal insulation materials currently used in my country are mainly organic thermal insulation materials and inorganic thermal insulation materials. However, due to the characteristics of the chemical properties of materials, no matter whether it is inorganic thermal insulation materials or organic thermal insulation ma...
