Abstract

The invention relates to a foam heat insulation plate. The foam heat insulation plate comprises the following components in parts by weight: 100 parts of waste PS (polystyrene) foam particles, 30-50 parts of No. 425 Portland cement, 50-100 parts of early strength superplasticizer, 200-300 parts of expanded perlite powder, 50-100 parts of glass fiber, 50-80 parts of PU (polyurethane) adhesive, 1-10 parts of resin soap foaming agent, 2-5 parts of flame retardant and 1-5 parts of fly ash. The product has excellent heat insulation performance, and the heat conductivity can achieve 0.05W / (m.K); the relative density is 0.3, the compression strength is 0.4-0.6MPa, and the bending modulus is 0.25MPa; and the foam heat insulation plate is non-toxic, odorless, less prone to combustion, acid and alkali-resistant, good in insulativity, convenient to construct and long in service life, can be widely used and can continuously replace existing materials.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foam insulation board and a preparation method thereof. Background technique [0002] With the development of social urbanization, science and technology, and humanization, foamed cement boards have been widely used in large-span industrial plants, warehouses, large locomotive garages, stadiums, exhibition halls, airports, large public facilities, activity rooms and In construction projects in various fields such as residential interlayer and partition wall insulation of residential buildings, it overcomes the thermal insulation difference caused by the foam insulation materials used in the past, the high thermal sensitivity rate, and the characteristics of cracks. [0003] At present, a lot of waste PS plastics are abandoned, causing solid waste pollution. With the popularization of the concept of humanization and the formation of a new harmonious society, it is very necessar...
