Abstract
The invention relates to a heat dissipation coating for an LED (Light-Emitting Diode) lamp. The heat dissipation coating comprises the following components in percentage by weight: 30-60% of silicon resin, 15-40% of n-butyl acetate, 5-10% of nanometer silicon dioxide, 13-40% of aluminum nitride, 15-20% of beryllium oxide, 1-2% of curing agent and 0.5-5% of dustproof agent and smoothing agent. The heat dissipation coating for the LED lamp has the advantages of high-radiation cooling property and convenience in use, and is used for reducing the surface temperature of a cooling cup, an aluminum substrate, a lamp cover and the like inside the LED lamp, so that the cooling effect is realized. Furthermore, the cooling coating provided by the invention has good protection and decoration functions. Meanwhile, not only can the dissipation cooling be realized, but also the heat dissipation coating has the characteristics of self-cleaning performance, water and fire resistance, insulation, and convenience in construction.
Description
Technical field
The present invention relates to a kind of heat radiation coating, be specifically related to a kind of heat radiation coating of the LED of being used for lamp.
Background technology
Along with the rapid expansion of LED lamp use range, prolong the problem that the LED lamp also becomes the continuation solution work-ing life.Most of at present heat-conducting glue that adopts solves LED lamp heat dissipation problem; But its employed material exists heatproof and ageing-resistant relatively poor and little to substrate bonding power, the not good and unhandy technical problem of radiating effect, is difficult to satisfy the requirement of people to the heat radiation of LED lamp.The producer that also has still can increase the production cost of LED towards selecting for use the material with high thermal conductance to set about.
Summary of the invention
The objective of the invention is above-mentioned deficiency, a kind of heat radiation coating of the LED of being used for lamp is provided to prior art.
The object of the invention is realized through following technical scheme:
A kind of heat radiation coating that is used for the LED lamp; Following steps: comprise following component by weight percentage, 30～60% silicone resin, 15～40% N-BUTYL ACETATE, 5～10% nano silicon, 13～40% aluminium nitride AlN, 15～20% beryllium oxide, 1～2% solidifying agent and 0.5～5% dust-proofing agent and smooth agent.
Beneficial effect of the present invention is: the heat radiation coating of LED lamp of the present invention has high radiation cooling property, and is easy to use, is used for reducing the surface temperature of the interior heat radiation cup of LED lamp, aluminium base, lampshade etc., thereby reaches cool effect.Coating has good protection and decoration functions simultaneously; When playing radiation cooling, the characteristics of good self-cleaning, water-repellancy, fire line, insulativity, antiacid alkali, easy construction are arranged also.
