Abstract

The invention provides a novel heat insulating plate. Active components of the novel heat insulating plate comprise 70-95 parts by weight of inorganic heat insulating particles and 5-30 parts by weight of an organic coating membrane material, wherein the outer surfaces of all inorganic heat insulating particles are coated with the organic coating membrane material to form 'capsule' type inorganic-organic composite heat insulating units, subsequently the 'capsule' type inorganic-organic composite heat insulating units are connected together by using a curing agent, and then a plate is formed in a mold, namely the novel heat insulating plate is obtained. The novel heat insulating plate disclosed by the invention can be used for improving the mechanical strength, also preventing exposure and water absorption of the inorganic heat insulating particles and limiting the air inside the 'capsule' type inorganic-organic composite heat insulating units as well so as to effectively reduce air motion inside the plate and reduce convective heat transfer, thus the heat conductivity coefficient is relatively as low as 0.032W / (m.K) to 0.040W / (m.K) and A-grade non-ignition can be truly realized, and therefore the novel heat insulating plate has both excellent fireproof performance and relatively-good heat insulation performance.

Description

technical field [0001] The invention relates to a novel insulation board and a preparation method thereof, belonging to the technical field of insulation boards. Background technique [0002] At present, thermal insulation materials for external walls can be divided into organic materials and inorganic materials. Among them, the organic materials are mainly polystyrene materials, foamed polyurethane, foamed phenolic resin, etc., and the inorganic materials are rock wool, foamed cement, glass wool, pearls, etc. Mainly rocks. Judging from the thermal conductivity of different thermal insulation materials, the thermal conductivity of organic thermal insulation materials is lower than that of inorganic thermal insulation materials, so the thermal insulation performance of organic materials is generally better than that of inorganic materials. For example, the thermal conductivity of polyurethane foam materials is lower than that of inorganic thermal insulation materials, so orga...
