Abstract
The invention discloses a micro-foaming cooling coating, which is prepared from the following raw materials in parts by weight: 70-80 parts of polyethylene E-309, 0.8-1 part of zinc dialkyl dithiophosphate, 1-2 parts of potassium titanate, 2-4 parts of powdered acrylonitrile-butadiene, 5-7 parts of trioctyl trimellitate, 4-6 parts of palm wax, 1-2 parts of diacetone alcohol, 6-8 parts of quasi-spherical silica powder, 1-2 parts of 2,2-dithienyl methyl glycolate, 1-2 parts of benzotriazole, 1-2 parts of aluminium hydroxide, 0.8-2 parts of fatty alcohol polyoxyethylene ether sodium sulfate and 8-14 parts of composite filler. The coating disclosed by the invention is good in cooling effect, smooth in foaming layer surface, lower in density, small in surface tension, stable to coat, and good in protective effect on a base material.
Description
Technical field
The present invention relates generally to a kind of powder coating, relates in particular to a kind of micro-expansion type heat radiation coating.
Background technology
Heat conduction and heat radiation coating is widely used in computer, notebook computer, LED illumination, communication, rectifier, and medical treatment and industrial equipments etc. has the field of heat radiation requirement, is mainly coated in the surface of scatterer.
The heat radiation coating of producing at present is generally applied to heat radiation and the heat radiation of LED light fixture of the components and parts of the electronic products such as CPU more, medium for brushing is had relatively high expectations, not strong for more coarse, loose body surface sticking power, result of use is undesirable, and the scope of application is less.
Summary of the invention
The object of the invention is just to provide a kind of micro-expansion type heat radiation coating.
The present invention is achieved by the following technical solutions:
A kind of micro-expansion type heat radiation coating, is characterized in that what it was comprised of the raw material of following weight parts:
Polyethylene E309 70-80, zinc dialkyl dithiophosphate 0.8-1, potassium titanate 1-2, powdered nitrile rubber 2-4, trioctyl trimellitate 5-7, palm wax 4-6, diacetone alcohol 1-2, torispherical silicon powder 6-8,2,2-dithienyl methyl glycolate 1-2, phenylpropyl alcohol triazole 1-2, aluminium hydroxide 1-2, polyoxyethylenated alcohol sodium sulfate 0.8-2, compounded mix 8-14;
Described compounded mix is comprised of the raw material of following weight parts:
Agalmatolite 20-30, Zirconium tetrafluoride 2-3, kaolin 30-40, wood charcoal powder 2-3, Sodium tetrafluoroborate 2-3, beta-diketon 0.2-0.4, the different monooctyl ester 3-4 of polyacrylic acid, 2-ethyl-4 Methylimidazole 0.7-1;
Above-mentioned kaolin is calcined to 2-3 hour at 600-700 ℃, after discharging is cooling, become powder with agalmatolite, Zirconium tetrafluoride mixed grinding; Different to above-mentioned wood charcoal powder and polyacrylic acid monooctyl ester is mixed, and dispersed with stirring 3-5 minute at 100-130 ℃, adds powder obtained above, and being stirred to temperature is 60-80 ℃, adds the each raw material of residue, fully ball milling, and granulation, particle diameter is 2-4 μ m, obtains described compounded mix.
A preparation method for micro-expansion type heat radiation coating, comprises the following steps:
By upper each raw material, mix, send into twin screw extruder, carry out melting, extrude and granulation, wear into fine powder and cross 160-200 mesh sieve, obtain described micro-expansion type heat radiation coating.
Advantage of the present invention is:
Coating of the present invention has good radiating effect, and coating foaming layer surfacing, density are lower, and surface tension is little, and film is stable, effective to the protection of base material.
