Abstract

The invention discloses an LED lamp heat dissipation coating difficult to fall off. The LED lamp heat dissipation coating is prepared from the following raw materials in parts by weight: 85-95 parts of main material, 2-6 parts of nano titanium dioxide compound, 1-2 parts of silane coupling agent KH560, 1-4 parts of epoxy-terminated polyether amine, 1-2 parts of maleic anhydride, 1-2 parts of maleic anhydride, 1-2 parts of calcium lignosulphonate, 1-2 parts of 1,5-naphthalene disulfonic acid, 2-4 parts of sodium dodecyl sulfate, 10-20 parts of glycerol, 1-2 parts of magnesium stearate, 0.5-1 part of pigment, 1-1.5 part of a dispersing agent, 1-2 parts of a leveling agent and 30-60 parts of water. The nano titanium dioxide compound is prepared by the following process: nano titanium dioxide,styrene, acrylic acid and talcum powder are uniformly mixed, potassium persulfate and water are added under the protection of nitrogen, heating and stirring are performed, centrifugal demulsificationand washing are performed, and then a butanol solution and toluene are added and the mixture is stirred, the mixture is subjected to centrifugation and washing to obtain the nano titanium dioxide compound.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a heat-dissipating coating for LED lamps that is not easy to fall off. Background technique [0002] Under the current background of rising global energy shortage concerns, energy conservation is an important issue we will face in the future. In the field of lighting, the application of LED lighting products is attracting the attention of the world. LED has high luminous efficiency, long service life, With many advantages such as energy saving and environmental protection, it is more and more widely used in many fields. [0003] However, at present, LED lamps are generally coated with heat-dissipating paint on the surface to conduct heat conduction to the internal heat. However, the current heat-dissipating paint for LED lamps still has the technical problems of low adhesion strength and easy peeling off. Contents of the invention [0004] Based on the technical problems exi...
