Composite board for fire and smoke exhaust pipe

Abstract

The invention discloses a novel special composite board for a fire and smoke exhaust pipe, and belongs to the field of fireproof panel. The novel special composite board is made by compounding high-intensity environment-friendly materials, medium-alkali cloth or alkali-free cloth and a supporting material by a hot pressing process, wherein, the high-intensity environment-friendly materials consist of 30-40% of magnesium oxide, 10-20% of magnesium chloride, 20-40% of quartz powder, 0.5-1% of a foaming agent, 0.5-1% of a modifier and 10-20% of water; the supporting material is of a centrifuge glass wool board or made by stirring 40% of magnesium oxychloride cement and 60% of foamed polystyrene materials, and the components are measured by weight percentage. The materials have the advantages of being non-inflammable, environmentally friendly, energy saving, light, highly intensive and the like; the board made from the materials has smooth surface, without rusting, going moldy or bittern accumulation, has low cost and more than 20 years of service life, is a superior material for fire control and smoke exhaust and ventilation, and has excellent popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of new boards for fire protection, and relates to a novel special board for fire-proof and smoke-exhaust air ducts. Background technique [0002] At present, most of the common fire-proof and smoke exhaust ducts in the market are made of iron sheet and glass fiber reinforced plastic sandwich foam, but iron sheet wastes a lot of resources, is easy to rust, has a short service life, and is rough in process, and the cost is also high, while glass fiber reinforced plastic is easy to return to halogen. The weight is relatively heavy, and the current market urgently needs to develop new special plates for fire-proof and smoke-exhaust ducts. Contents of the invention [0003] In order to overcome the shortcomings of current fireproof and smoke exhaust duct materials, the purpose of the present invention is to provide a new type of fireproof and smoke exhaust duct special board that has a long service life, is not easy to r...
