Technical field
The invention belongs to new material technology field, relate to a kind of powder coating and preparation method thereof, particularly a kind of aluminium section bar is with sand streak powder coating and preparation method thereof.
Background technology
Existing powder coating, appearance of film majority are Gao Guang, half light or low light series, in carrying, construction and use, are prone to produce scratch; Under atmospheric condition, because of aging loss of gloss and produce efflorescence, lost original decorative effect very soon.Along with expanding economy, development of technology with constantly bring forth new ideas, developed at present and multiplely can change the outer texture auxiliary agent of form at present of filming, add this analog assistant, film coated surface is produced such as grain effects such as decorative pattern, mallear stria, moire and sand streaks.Thereby make the powder coating ornaments more rich and varied.The sand streak powder coating is filmed, because illumination produces scattering, gives people's impression comfortable; Hardness of film is high; Feel is smooth to be difficult for being scratched and advantage such as ageing-resistant, receives people's favor, is widely used in the application on aluminum products surfaces such as building doors and windows, electric appliance and electronic product, five metals furniture; Application Areas is in the ascendant, makes that just sand streak series powder coating is developed accordingly.
Summary of the invention
In order to solve the weak point that prior art exists, primary and foremost purpose of the present invention is to provide a kind of aluminium section bar to use the sand streak powder coating.The hardness of film of this powder coating is high, damage resistant is anti-aging, can give the more comfortable visual impression of people, and have the different texture effect.
Another object of the present invention is to provide the preparation method of above-mentioned aluminium section bar with powder coating.
A purpose more of the present invention is to provide the application of above-mentioned aluminium section bar with powder coating.
The object of the invention is realized through following technical scheme: a kind of aluminium section bar is used the sand streak powder coating, and this sand streak powder coating is formed by following raw material preparing by heavy per-cent:
The weight ratio of said saturated terminal carboxyl polyester resin and triglycidyl isocyanurate is 93.1:7～94.6:7.
Above-mentioned aluminium section bar comprises following operation steps with the preparation method of sand streak powder coating:
(1) with the saturated terminal carboxyl polyester resin of weight percent 50～60%; The triglycidyl isocyanurate of weight percent 3.7～4.5%; The titanium oxide of weight percent 17～27%; The process white of weight percent 13～20%; The wilkinite of weight percent 0.2～1.5%; The sand streak agent of weight percent 0.2～0.7%; The carbon black of weight percent 0.3%; Weight percent 0.1～0.2% pink; Pre-mixing in the blue input of the phthalein of weight percent 0.1～0.2% compounding jar;
(2) starting material after the pre-mixing are melt extruded and be pressed into sheet stock;
(3) it is broken sheet stock to be cooled off the laggard row of room temperature, carries out fine pulverizing again;
(4) material with fine pulverizing sieves, and obtains aluminium section bar and uses the sand streak powder coating.
The said premixed time of step (1) is 3～4 minutes.
Step (2) is said to melt extrude and is meant with the starting material of twin screw extruder after to pre-mixing and carries out the melting mixing homodisperse and extrude that wherein, the temperature in forcing machine I district is 115～125 ℃, and the temperature in II district is 105～115 ℃.
The said fine pulverizing of step (3) is meant with 10～100 microns of the sheet stock pulverized powder particle diameter of air classifying supper micron mill after with fragmentation.
The said screening of step (4) is meant that using rotating screen that powder coating is sized to median size is 25～35 microns.
Above-mentioned a kind of aluminium section bar is with the application of sand streak powder coating at aluminium section bar.
The present invention possesses following outstanding advantage and effect with respect to prior art:
(1) add the sand streak agent in the present invention prescription, filming after the curing produces the grain effect with sand streak, gives the euphorosia sense since film hard, feel is smooth, is producing, processing, is being difficult for producing in using and scratches, and weather resistance is excellent.Fill up the blank of powder coating kind outward appearance dullness.
(2) added of the auxiliary packing of the big wilkinite of oil number in the prescription as the sand streak agent; Bentonitic adding can be adjusted the thickness and the slickness of film coated surface texture; Greatly improved the hardness of sand streak film coated surface; Strengthen the film coated surface scratch resistant performance, and can practice thrift the usage quantity of expensive sand streak agent again, reduced the cost of powder coating.
(3) on production technique, when producing the sand streak powder coating, the height the when rotating ratio of extruder screw is produced ordinary powder coating has improved production efficiency, reduces production costs.
