Abstract

A thermocured, heat conductive and heat radiating paint for an LED lamp is prepared by the following raw materials by weight: 40-45 parts of polyacrylic resin, 5-8 parts of polyurethane resin, 4-6 parts of polyacrylamide, 6-8 parts of isophorone diamine IPDA, 20-24 parts of xylene, 2-3 parts of silane coupling agent KH550, 1-2 parts of aluminium powder, 8-12 parts of ethyl acetate, 2-4 parts of benzyltrimethylammonium tribromide, 10-12 parts of aluminium nitride, 2-3 parts of beryllia, and 4-5 parts of film forming auxiliary agent. Aluminium nitride powder, the beryllia and the aluminium powder are added, so as that the paint has high heat conduction rate and good heat radiation effect, and can be long-term used under 200 DEG C without change of mechanical property; polyacrylic resin is used, so as that the paint has advantages of excellent fullness, glossiness, hardness, solvent resistance and weatherability, without color change and brightness reversion when high temperature baked; and the paint has advantages of large adhesion stress, not-easy shedding, aging resistance and long usage life.

Description

technical field [0001] The invention belongs to the technical field of paints, and relates to a heat-dissipating paint, more specifically, a heat-curing heat-conducting and heat-dissipating paint for LED lamps and a preparation method thereof. Background technique [0002] As LED technology has received widespread attention as a new generation of lighting technology in recent years, the power of LED has increased, and the heat dissipation problem has also attracted more and more attention. At present, most of the heat-conducting adhesives are used to solve the heat dissipation problem of LED lamps, but the materials used have technical problems such as poor temperature resistance and aging resistance, low adhesion to the substrate, poor heat dissipation effect and inconvenient operation, which are difficult to meet people's expectations. Requirements for heat dissipation of LED lamps. Some manufacturers also start to select materials with higher thermal conductivity, but th...
