A kind of anti-ultraviolet paint
Technical field
The present invention relates to heat radiation coating field, is exactly a kind of anti-ultraviolet paint.
Background technology
Heat radiation coating is a kind of radiating efficiency that improves body surface, reduces the existing heat radiation coating function singleness of speciality coating of system temperature, cannot meet people's multiple demand.
Summary of the invention
The object of the present invention is to provide a kind of anti-ultraviolet paint.
Above-mentioned purpose realizes by following scheme:
A kind of anti-ultraviolet paint, is characterized in that: it is to be made by the raw material of following weight parts:
A material 40-50, B material 30-40;
Described A material is made by the raw material of following weight parts:
Epoxy acrylic resin 60-70, antioxidant 264 1-2, polyethylene wax powder 1-2,2-ethyl-4-methylimidazole 1-2, nano-ceramic powder 2-5, cyanoethyl cellulose 1-2, silane coupling agent KH530 1-2, ethyl acetate 60-70;
Described B material is made by the raw material of following weight parts:
Epoxy acrylic resin 50-60, n-butyl acetate 1-2, feldspar in powder 3-5, nano silicon 1-2, zinc oxide 6.0-7.0, pentanoic 1-2, dimethyl phthalate 1-2, secondary alcohol Soxylat A 25-7 0.5-1, isomery polyoxyethylenated alcohol 0.2-0.4, UV light absorber 2.4-3.5, propylene glycol 40-60, nano-calcium carbonate 1-2;
Described a kind of anti-ultraviolet paint, is characterized in that: preparation method comprises the following steps:
(1) A is expected to each raw material mixes, be heated to 70-80 DEG C, stirring reaction 1-2 hour under the speed of 1800-1900r/min, obtains A material for subsequent use;
(2) B is expected to each raw material mixes, be heated to 40-50 DEG C, stirring reaction 20-40 minute under the speed of 400-600r/min, obtains B material for subsequent use;
(3) A material, B are expected to mixing and stirring by weight, while being ground to 60-70 μ m after, to obtain final product.
When construction, heat radiation coating spraying application is dried 1 hour at 60 DEG C, gets final product film forming, makes 80-100 μ m heat radiation coating.
Beneficial effect of the present invention is: the invention enables UV light absorber and all the other raw materials well compatible, synergy, has the excellent ultraviolet function that absorbs, and has improved the anti-ultraviolet property of heat radiation coating.
Embodiment
A kind of anti-ultraviolet paint, it is to be made by the raw material of following weight kg:
