Abstract

The invention discloses a foam glass insulation board, comprising the following ingredients in parts by weight: 40-50 parts of desulfurization gypsum, 20-22 parts of foam glass, 20-30 parts of coal ash, 20-40 parts of mineral powder, 24-26 parts of water, 2 w / w% of lime, and 1-2 w / w% of admixture. The insulation board is prepared from foam glass scraps; the waste foam glass and the waste such as the desulfurization gypsum, the coal ash and the like of a thermal power plant are changed into precious resources by utilizing local resources; not only can the targets of saving energy and reducing emission of buildings be solved; but also the problems of no place to stack waste products and the like are solved; the pollution on the environment is reduced; the foam glass insulation board accords with the principle of sustainable development; the heat conductivity coefficient of the prepared foam glass insulation board is 0.10-0.15 w / m.k; the compressive strength achieves over 0.8 Mpa; and the volume density is 600-700 kg / m<3>.

Description

technical field [0001] The invention relates to a building material, in particular to a foam glass insulation board. Background technique [0002] At present, foam glass is widely used in domestic and foreign buildings because of its excellent thermal insulation performance. However, in the production process, a large amount of discarded foam glass scraps will be generated due to cutting and other reasons. According to the survey, a foam glass company in Jiaxing produces 20,000 cubic meters of waste foam glass every year, causing great environmental pollution and waste of resources. Recycling waste foam glass scraps, supplemented by thermal power plant waste desulfurization gypsum and fly ash and other cementitious materials to make self-insulation boards, not only energy-saving, environmental protection, but also can avoid alkali-aggregate reaction, and achieve fire prevention in essence , durable and corrosion-resistant. The raw material price of the insulation board is...
