Abstract

The invention discloses a heat conducting film. The heat conducting film comprises raw materials in parts by weight as follows: 80-100 parts of polyethylene oxide, 55-60 parts of polytetrafluoroethylene, 60-70 parts of polyester, 70-80 parts of polyvinyl chloride, 50-80 parts of polyethylene, 50-60 parts of polypropylene, 15-18 parts of carbon nanoparticles, 12-15 parts of nano-silver powder, 10-15 parts of polyethylene-polypropylene, 5-8 parts of rosin, 10-12 parts of silicone oil, 15-18 parts of alcohol ester resin and 10-12 parts of deionized water. The heat conducting film has the characteristics of being high in heat conductivity, stretch-resistant, bending-resistant, good in lubrication effect, high in strength, large in specific surface area and high in chemical reactivity, heat conductivity coefficient and filling performance, and the mechanical properties and heat conductivity of the film can be improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a thermally conductive film with high thermal conductivity, tensile resistance and bending resistance. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of polyester film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. Films are widely used in electronics, machinery, printing and other industries. [0003] For example, polyimide film, which is a new type of organic polymer film, is composed of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a very strong solvent N,N-dimethylacetate It is formed by polycondensation in amide (DMAC), cast into a film, and then imidized. It has excellent mechanical properties, electrical properties, chemical stability, radiation resistance, high temperature...
