Self-heating plywood cladded with conductive plastics having the properties of electric conduction and heat storage

摘要

The present invention relates to a heat generating plywood in which a conductive heat storage plastic is bonded to a wood plate or plywood.;The conductive heat storage plastics of the present invention are 40 to 70 wt% of PVC resin, 30 to 60% of plasticizer, graphite powder corresponding to 30 to 40 wt% of fibric seed content, and 10 of fibric seed content. It consists of latent heat fine particles corresponding to ˜40 wt%, and has technical characteristics. When forming the plate by mixing the above components uniformly, the copper plate as an electrical connection terminal is inserted at both ends of the plate plastic to become a conductive heat storage plastic. .;The particle size of the graphite powder constituting the conductive heat storage plastic of the present invention is in the range of 10 to 50㎛, the latent heat particulate is to give heat storage performance to the plastic, the average particle size of about 30 to 50㎛, the internal material is paraffin wax (paraffin wax ) And polyoxy methylene urea is used as the outer wall material to enclose the inner material.;The heat generating plywood of the present invention has a laminated structure, the laminated structure of which one of the wood plate or plywood as the top layer, the lower layer in the order of insulation layer-conductive heat storage plastic-insulation layer-insulation layer-wood plate or plywood It is manufactured by laminating and bonding.;The conductive heat storage plastic of the present invention has a uniform surface temperature and a surface temperature of about 60 ° C., so that there is no risk of fire due to overheating, and there is a problem of disconnection due to long-term use unlike conventional products in which heating wires are arranged. There is no advantage in that the service life is very long.
