Abstract

The invention relates to the field of heat preservation materials, and provides a graphene heat accumulation pad and a preparing method thereof. The graphene heat accumulation pad comprises a damp-proof layer at the bottom and a heat accumulation layer on the top, the heat accumulation layer fits the upper surface of the damp-proof layer, the damp-proof layer is made from a radiation crosslinkingpolyethylene foaming material, the heat accumulation layer is prepared from a graphene / organic compound phase-change material, and a layer of aluminum foil fits the bottom face of the damp-proof layer. The invention provides a novel thin film material with the functions of heat preservation, heat accumulation and damp proofing, and the novel thin film material is suitable for thermal insulation materials of various floors and floor heating systems.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a graphene heat storage pad and a preparation method thereof. Background technique [0002] When installing general building floors, heating floors, heating membranes, heating panels, etc., thermal insulation materials need to be installed. Traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and waterproof. Poor performance, short service life and other defects. [0003] The invention of authorized notification number CN106489050B discloses a vacuum heat insulation mate...
