Abstract

The invention relates to a photo-cured heat-conductive film. The photo-cured heat-conductive film is composed of the following components in percentage by weight: 9.26-20.44% of modified acrylate oligomer, 9.37-32.58% of acrylic monomer, 2.11-5. 82% of a photoinitiator, 0.3-5% of auxiliaries and 55.75-78.96% of a heat-conductive filler, and prepared by a production method comprising the steps of mixing raw materials, moulding by casting, and curing. The photo-cured heat-conductive film disclosed by the invention has the following advantages: the heat-conductive film is prepared by mixing modified acrylate oligomer, the acrylic monomer, the photoinitiator, the auxiliaries and the heat-conductive filler, thus improving the existing production process of films, improving the running efficiency of equipment, reducing the volatilization phenomena of organic solvents in the existing metal material thermal control and solvent moulding process, improving the use effect, simplifying the existing processing process, reducing heating steps, avoiding ingredient volatilization, and achieving a good use effect.
