Abstract
The invention discloses self-heat dissipation type environment-friendly powder coating. The self-heat dissipation type environment-friendly powder coating is prepared from the following raw materials in parts by weight: 90-97 parts of chlorinated polyethylene, 2-3 parts of terpineol, 4-5 parts of nanometer magnesium oxide, 3-5 parts of nanometer silicon oxide, 2-3 parts of oleic acid polyoxyethylene ester, 4-6 parts of phthalate, 1-2 parts of hydroxypropyl methyl cellulose, 3-5 parts of nanometer bentonite, 2-4 parts of maleic anhydride grafted polypropylene, 1-2 parts of hexamethylphosphoric triamide, 3-5 parts of decabromodiphenylethane, 1-2 parts of stannic oxide and 10-14 parts of modified filler. The powder coating disclosed by the invention has no toxic or side effect and is safe and reliable; the materials are uniformly dispersed and are unlikely to settle or separate out by adding various nanometer raw materials, so that the self-heat dissipation and far infrared release effects of the materials can be fully exerted, and a very good heat dissipation effect is achieved.
Description
Technical field
The present invention relates generally to a kind of powder coating, relates in particular to a kind of from heat radiating type environmental protection powder 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 from heat radiating type environmental protection powder coating.
The present invention is achieved by the following technical solutions:
From a heat radiating type environmental protection powder coating, it is characterized in that what it was comprised of the raw material of following weight parts:
Chlorinatedpolyethylene 90-97, Terpineol 350 2-3, nano magnesia 4-5, nano silicon oxide 3-5, polyoxyethylene oleic acid ester 2-3, phthalic ester 4-6, HPMC 1-2, nano-bentonite 3-5, maleic anhydride inoculated polypropylene 2-4, HMPA 1-2, TDE 3-5, tindioxide 1-2, modified filler 10-14;
Described modified filler is comprised of the raw material of following weight parts:
Loess 20-24, alkali magnesium sulfate crystal whisker 6-8, gibbsite 5-7, the cross-linking modified polyvinyl alcohol glue 2-4 of tolylene diisocyanate, hexagonal boron nitride 2-3, Stockholm tar 1-2;
Above-mentioned loess is calcined to 1-2 hour at 600-700 ℃, be cooled to room temperature, become powder with hexagonal boron nitride mixed grinding; Above-mentioned alkali magnesium sulfate crystal whisker is mixed with gibbsite, and heated and stirred 3-4 minute at 120-160 ℃, reduces temperature to 60-70 ℃, adds the cross-linking modified polyvinyl alcohol glue of tolylene diisocyanate, and 200-300 rev/min is stirred 10-20 minute; Each raw material after above-mentioned processing is mixed with each raw material of residue, and fully ball milling, obtains described modified filler.
A preparation method from heat radiating type environmental protection powder coating, comprises the following steps:
Above-mentioned each raw material is mixed, and 1200-1600 rev/min of high speed dispersion, to mixing, melt extrudes, and abrasive dust below 15 μ m, obtains described from heat radiating type environmental protection powder coating to fineness.
Advantage of the present invention is:
Powder coating of the present invention has no side effect, safe and reliable, and the various nano raw materials that add make each material dispersion equal, and free settling or separate out, can not give full play to their heat radiation certainly, far infrared release action, plays good radiating effect.
