Abstract

The invention aims to provide a rollable exothermic plastic material. The rollable exothermic plastic material is characterized by comprising a composite carbon material membrane and two flexible insulating layers covering two surfaces of the composite carbon material membrane, and the outer surface of the insulating layer on one side is covered with a reflective coating. The rollable exothermic plastic material has the advantages that the rollable exothermic plastic material has excellent flexibility and meanwhile is optimal in high temperature resistance, exothermic uniformity and electrothermal performance, and exothermic membrane resistance can be adjusted conveniently through content of nano silicon carbon particulates and structural adjustment; the advantages of convenience in processing and low cost of a carbon crystal electrothermal material are kept, and the defect of poor flexibility of the carbon crystal electrothermal material is overcome.

Description

technical field [0001] The invention relates to a heating material, in particular to a curlable heating plastic material. Background technique [0002] Electrothermal film heating is one of the emerging heating methods in the world. It is a new heating method that uses electric energy as the source and conducts heat transfer through infrared radiation. Because of its excellent properties such as high pressure resistance, moisture resistance, wide temperature range, high toughness and low shrinkage, it has been more and more widely used. However, most of these heating materials have short service life, hard and brittle texture, and are difficult to fold, which greatly limits the scope of use. The existing flexible electric heating film is mainly developed in two ways: carbon fiber electric heating film and polymer flexible heating film. Carbon fiber electric heating film has excellent performance, but the cost is high, and the scope of promotion in actual life consumption is...
