Gypsum-based self-humidity-control ceiling decoration material

Abstract

The invention relates to a gypsum-based self-humidity-control ceiling decoration material which comprises a water-soluble non-combustible ceramic protective layer, an organic-inorganic composite toughening layer and a flame-retardant thermal insulation layer, wherein the organic-inorganic composite toughening layer is flame-retardant thermal insulation polymer mortar and comprises the following components: a binding material S, ceramic beads, hydroxyethylmethylcellulose, redispersible emulsion powder, limestone flour and modified expansible graphite; and the flame-retardant thermal insulationlayer comprises the components of modified expandable polystyrene and modified expansible graphite. The flame-retardant thermal insulation board is mounted on the wall space in a manner of combining bonding and anchoring. The bonding performance of the flame-retardant decorative board prepared by the method disclosed by the invention meets the national standard requirement, and the base material is endowed with flame-retardant properties. Moreover, the mechanical property of the base material is not influenced, the formaldehyde release amount is on a level E1 or higher, and the material is safe and environmental-friendly. Meanwhile, the natural texture of wood is maintained, and the decorative effect is excellent.

Description

technical field

[0001] The invention relates to a flame-retardant decorative board, in particular to a gypsum-based self-humidity-adjusting ceiling decoration material. Background technique

[0002] At present, there are many researches on the fire-retardant treatment of wood and wood materials, but the existing methods for fire-retardant treatment of wood materials have various defects. For example, CN1911613A discloses a wood flame-retardant treatment process, which is to put wood into a sealed container, vacuum-treat the container including wood, and then input the fire-retardant liquid into the container in a vacuum state through a high-pressure pump. In the process, after the fire retardant solution reaches saturation in the wood, the wood is taken out and dried; the fire retardant solution contains ammonium sulfate, diammonium hydrogen phosphate, boric acid and borax. This method is a method of impregnating flame retardant under pressure. There are certain problems in...
