Abstract
The invention discloses heat-dissipation paint for an LED lamp, which is characterized by comprising the following components in percentage by mass: 30 to 50 percent of organosilicon polyurethane prepolymer, 10 to 20 percent of mixed solvent, 1 to 5 percent of silane coupling agent KH560, 8 to 15 percent of beryllium oxide, 15 to 50 percent of aluminium nitride and 1 to 5 percent of oleinic acid. A preparation method comprises the following steps of: firstly, uniformly blending the liquid components; secondly, adding solid components and uniformly stirring; and finally, grinding on a grinder and then packaging. The heat-dissipation paint for the LED lamp in the invention has the advantages of temperature resistance, aging resistance, high adhesion and good heat-dissipation effect.
Description
Technical field
The invention belongs to technical field of coatings, relate to a kind of heat radiation coating, more particularly, relate 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 LED lamp and also become urgent problem work-ing life.Adopt heat-conducting glue to solve LED lamp heat dissipation problem at present, but there is heatproof and ageing-resistant poor in its employed material, the technical problem little to the base material cohesive force, that radiating effect is not good and construction is inconvenient is difficult to satisfy the requirement of people to the heat radiation of LED lamp.
Summary of the invention
The objective of the invention is to overcome existing defective, provide that a kind of to have cohesive force big, ageing-resistant, heat extraction coefficient big, be used for the heat radiation coating of LED lamp for solving the above problems.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of heat radiation coating that is used for the LED lamp, content is 30～50% by the organic silicon polyurethane prepolymer by mass percentage, mixed solvent is 10～20%, silane coupling agent KH560 is 1～5%, beryllium oxide is 8～15%, and aluminium nitride is 15～50%, and oleic acid is that 1～5% component is formed; Wherein the molecular characterization of organic silicon polyurethane prepolymer is:
Described mixed solvent is an acetone, different fluorine that ketone, and ethyl acetate mixture, the mass ratio of its mixed solvent is: acetone
:Different fluorine that ketone
:Ethyl acetate=1
:10
:2.
The advantage and the beneficial effect of the heat radiation coating of a kind of LED of being used for lamp of invention are mainly reflected in:
Single component, ageing-resistant, cohesive force is big, and good heat dissipation effect can be at 200 ℃ of following life-time service, and mechanical property is constant.
