Abstract

The invention belongs to the field of heat-preservation sheets and discloses a composite nanometer heat-preservation and thermal-insulation sheet. The sheet is prepared from polystyrene resin, glass fibers, quartz powder, aluminum carbonate and other materials. The preparation method comprises the following steps: (1) stirring polystyrene resin, the glass fibers, polypropylene foamed plastic, cis-2-butene and 2-methylbutane until the materials are uniformly mixed to obtain a mixed material; (2) grinding quartz powder, aluminum carbonate, potassium sulfate and the like; (3) mixing and adding the ground material into the mixed material obtained in the step (1) while uniformly stirring; and (4) molding the mixed material which is uniformly stirred in the step (3) by casting to prepare the composite nanometer heat-preservation and thermal-insulation sheet.

Description

technical field [0001] The invention belongs to the field of thermal insulation boards, and relates to a thermal insulation board and a preparation method thereof, in particular to a composite nano thermal insulation board and a preparation method thereof. Background technique [0002] Common thermal insulation materials, inorganic materials include expanded perlite, aerated concrete, rock wool, glass wool, etc., organic materials include polystyrene foam, polyurethane foam, etc. The thermal insulation performance of these materials is mainly determined by the thermal conductivity of the material (the index is thermal conductivity). The harder it is for a material to conduct heat, the better its thermal insulation performance will be. Generally speaking, the common feature of thermal insulation materials is that they are light, loose, porous or fibrous, and use the air that does not flow inside to block heat conduction. Among them, inorganic materials have the characterist...
