Abstract

The invention discloses efficient heat-dissipation paint for an LED lamp housing. The efficient heat-dissipation paint is prepared from the following raw materials in parts by weight: 55-74 parts of keto-aldehyde resin, 30-46 parts of polyimide resin, 15-30 parts of acrylate, 12-25 parts of silica sol, 11-17 parts of nano diatomite, 10-20 parts of styrene-acrylic emulsion, 2-6 parts of nano silicon dioxide, 8-14 parts of polyethylene glycol, 2-5 parts of a film-forming aid, 5-10 parts of active aluminum oxide, 7-11 parts of methyl silicone oil and 6-10 parts of roasted kaolin. The efficient heat-dissipation paint has the effects of being high in cooling property, convenient to use, and capable of reducing the surface temperature of the illuminating lamp housing to achieve the cooling effect.

Description

technical field [0001] The invention relates to the field of lamp lighting, in particular to a high-efficiency heat dissipation paint for LED lamp shells. Background technique [0002] With the rapid expansion of the scope of use of LED lamps, prolonging the service life of LED lamps has also become an urgent problem to be solved. With the increase of LED power, the heat dissipation problem has also been paid more and more attention. At present, thermal conductive adhesive is used to solve the heat dissipation problem of LED lamps, but the materials used have poor temperature resistance and aging resistance, low adhesion to the base material, poor heat dissipation effect and inconvenient construction. It is difficult to meet people's expectations for LED lamps. cooling requirements. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency heat dissipation coating for the housing of an LED lamp to solve the above-mentioned tech...
