The invention provides a method for improving performance of a lamp radiator. At first, graphene is added into an aqueous solvent, stirred and uniformly dispersed through ultrasonic waves, the concentration of the graphene is controlled between 6% and 30%, and graphene coating is prepared; then, the obtained graphene coating is sprayed on the surface of the lamp radiator under normal temperature; finally, the lamp radiator coated with the graphene coating is cured. According to the method for improving the performance of the lamp radiator, the performance of the lamp radiator is remarkably improved; meanwhile, the process is simple and feasible, cost is low, and industrial mass production can be achieved.
Description
Technical field
The present invention relates to radiator field, particularly a kind of method improving lamp radiator performance.
Background technology
Along with the arrival of information age, there is high-power, micro-structural, densification and lighting development trend in electronic product, and heat radiation is the bottleneck problem of restriction electronic product development.Research display, it is that the heat dissipation problem solving electron trade is very urgent because caused by overheated that the electronic product of 55% lost efficacy.Along with the development of modern Lighting Industry, occurred with large quantities of lighting such as LED, plasma lamp, the give out light heat dissipation problem in source such as LED, plasma lamp becomes the bottleneck of its illumination development.Because light fixture itself and chip can produce a large amount of heats in the middle of use procedure, especially plasma lamp and LED point-like illuminating source, the heat produced concentrates in minimum region, if the heat produced cannot distribute timely and effectively, temperature can be caused to raise rapidly, thus speed-up chip and potting resin is aging, make chip failure, and then directly affect service life and the luminous efficiency of light fixture, so heat dissipation problem is directly connected to the development prospect of light fixture.
Prior art has employing radiator can reach certain heat radiation and anti-corrosion effects through MAO process and oil spout process, but production cost is high, environmental hazard large, is unfavorable for long-term suitability for industrialized production.Explore environmental protection, low production cost and effectively improve the focus that radiator performance method has become research.
Summary of the invention
For above problem, patent object of the present invention is to devise a kind of method improving lamp radiator performance, has clear improvement to the hot device heat dispersion of light fixture, simultaneously its technique simple possible, with low cost, can realize industrial volume production.Technical scheme of the present invention is as follows:
Improve a method for lamp radiator performance, comprise the steps:
Steps A, joins Graphene in aqueous solvent, stirs, is uniformly dispersed with ultrasonic wave, and the concentration controlling Graphene, between 6% ~ 30%, prepares Graphene coating;
Step B, Graphene coating steps A obtained is sprayed on the surface of lamp radiator at normal temperatures;
Step C, is cured the lamp radiator of graphite spraying alkene coating, solidification temperature 130 DEG C ~ 160 DEG C, 10 ~ 40 minutes hardening times.
Further, lamp radiator of the present invention is LED lamp heat sink.
Further, lamp radiator of the present invention is plasma lamp radiator.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
Graphene has single layer structure, be considered to the thinnest, the hardest, toughness preferably and the minimum nano material of density.The thermal conductivity factor of Graphene, up to 5300w/mk, is current heat conductivility best material; Under normal temperature, its electron mobility is more than 15000cm
2/ vs, higher than CNT or silicon crystal, resistivity is 10
-8Ω cm, lower than copper or silver, is the material that resistivity is minimum; The specific area of Graphene is up to 2630m
2/ g, solid density is 0.77mg/m
2, be material thin and the lightest at present.Graphene is added in matrix alloy mainly with the form of nanometer sheet the performance improving alloy.First, Graphene is because the large schedule of reinforcement of refined crystalline strengthening, super large interface enhancing and shear stress transfer strengthening three improves the intensity of alloy; Secondly, large specific area and the distinctive pleated structure of Graphene put forward heavy alloyed toughness; Finally, monoatomic layer arrangement causes high chemical stability and compact structure to improve alloy corrosion performance.The present invention proposes a kind of method improving lamp radiator performance, adopt Graphene coating, the hot device heat dispersion of light fixture is had clear improvement.
The invention provides technology real time steps as follows:
(1) die casting or punching press radiator
Select the alloy material of high-quality, by die casting or Sheet Metal Forming Technology, according to required shape and specification, be made into radiator, and radiator is carried out simple surface treatment, polishing, polishing.
(2) Graphene coating
Preparation High-performance graphene coating.Utilize ultrasonic wave, Graphene is dispersed in aqueous solvent effectively, uniformly and is prepared into coating, and the concentration ratio of Graphene controls between 6%-30%, to reach good heat dispersion and adhesive force requirement.
(3) spraying coating process
