Heat dissipation material used for producing LED lamp shells

Abstract

The invention discloses a heat dissipation material used for producing LED lamp shells. The heat dissipation material comprises a heat dissipation layer and an adhesive layer. The adhesive layer is composed of, by weight, 27-36 parts of polyethylene glycol isophthalate, 11-17 parts of polybutylene terephthalate, 31-37 parts of epoxy resin, 11-17 parts of graphene powder, and 9-13 parts of methacryloxy silane. The heat dissipation layer is composed of, by weight, 15-17 parts of ceramic powder, 5-12 parts of polyethylene glycol, 7-13 parts of graphene powder, 9-13 parts of epoxy resin, 9-14 parts of polyimide, 3-7 parts of triethoxy chlorosilane, 11-17 parts of polyethylene glycol, 1-3 parts of magnesium isooctanoate, 2-4 parts of zinc borate, 1-3 parts of vanadium diboride, 2-5 parts of sodium borohydride, 0.1-0.3 part of natrolite, and 0.1-0.4 part of medical stone powder. By means of the heat dissipation material, the heat dissipation capacity of LED lamps under the working conditioncan be improved, thus the service life of the LED lamps is prolonged, and the working stability of the LED lamps is improved. In addition, the heat dissipation material is provided with the adhesive layer, the function of improving adsorption capacity of the heat dissipation layer is achieved, and heat can be transferred efficiently.

Description

technical field [0001] The invention relates to LED lamps, in particular to a heat dissipation material for producing LED lamp shells. Background technique [0002] LED lighting fixtures are the general term for LED lighting fixtures, which refer to appliances that can transmit light, distribute and change the light distribution of LED light sources, including all parts and components required to fix and protect LED light sources except for LED light sources, as well as connections to power sources Required wiring accessories. With the further maturity of LED technology, LED will achieve more and better development in the field of design and development of living room lighting fixtures. However, LED lamps also generate heat during the lighting process. If the temperature of the lamp is too high, it will affect the service life and operation stability of the lamp. Based on the above problems, improving the heat dissipation capability of LED lamps under working conditions ha...
