Description
Technical field
The present invention relates to the technical field of surface of metallic pigment, specifically be meant a kind of preparation method of coated aluminium powder pigment.
Background technology
Aluminium powder pigment is one of important metallic pigment, and main Application Areas has industrial coating, car paint, printing-ink and plastic working industry.Why aluminium powder pigment has many Application Areass, and reason is that it has the characteristic that is different from other pigment: (1) " changeable colors along with angle " effect or " double-colored " effect.Promptly observe from different perspectives when containing the coating of aluminium powder, the color of coating can change with the angle variation.During the top view coating, coating color is very bright; Its colour-darkening during side-looking.Aluminium powder pigment is widely used in decorative paint because of this effect.(2) aluminium powder pigment has the ability of good reflection ray and reverberation.Aluminium powder pigment can form the successive metallic membrane when film forming, can reflect visible light, UV-light and infrared light.Full spectrographic reflection is silvery white in color to visible light, makes it have good decorate properties; Make it that heat-insulating property of anti-heat be arranged to infrared reflection of light; Then but supercoat is unlikely destroyed by ultraviolet ray and aging and then prolonged the life-span of coating to the ultraviolet reflection of light.Therefore it is used for petroleum industry, chemical industry and carrier vehicle, pipeline.Some hot areas abroad, aluminium powder pigment is used for roofing flux paint brush roofing in a large number, has reduced room temp effectively.(3) aluminium powder pigment has the covering power of change in a big way.The technical indicator of expressing this performance of aluminium powder pigment is a water surface opacifying power, and a gram aluminium powder hides the water surface can be at 1000～30000cm
2Aluminium powder pigment is small aluminium scale, and its diameter and thickness have certain ratio.Thickness is less, and the little kind of diameter difference has bigger water surface covering power, and this characteristics not only have its economy, and the function of glossy variation.
Product such as coating and paint major part is weak acid or weakly alkaline, aluminium powder pigment in coating and the paint is in storage or use, because of being subjected to the corrosion of acid or alkaline matter, its color can become canescence by bright metallic color gradually, and this has had a strong impact on the performance of product.In addition, be subjected to the restriction of environmental factors, coating and paint industry just develop towards the direction that reduces volatile organic matter, and water-borne coatings is the reasonable selection that addresses this problem.When aluminium powder pigment is used for water-borne coatings, can produce many adverse influences, as: dispersion stabilization etc.Yet the most important thing is that water-borne coatings is prepared under alkaline condition mostly, aluminium powder pigment is corroded easily, and its consequence not only can make aluminium powder pigment lose metalluster gradually, and can produce a large amount of H
2, blast easily.Therefore, be necessary aluminium powder pigment is carried out surface treatment.
At present, the surface treatment method of aluminium powder pigment mainly contains two kinds: physical protection method and chemoproection method.The physical protection method promptly at the resin of aluminium powder surface brush layer of transparent as protective layer.Because the bonding force on resin and aluminium powder surface a little less than, therefore, resin is easy to come off from the aluminium powder surface, thereby has lost the provide protection to aluminium powder.The chemoproection method mainly is divided into deactivation method, additive method and coating method.Deactivation method is the method for chemical protection that uses the earliest, and this method is to handle aluminium powder with passivator, makes its surface form one deck passive film.The most effective passivator is chromic salt, but because the sexivalent chromium ion causes very big harm to environment, and carcinogenesis is arranged, so people are seeking new alternative method.Additive method is to add to suppress aluminium powder pigment corrosive material in systems such as coating; additive is that to the provide protection of aluminium powder pigment it can be adsorbed on the surface of aluminium powder pigment; but because a little less than this adsorption; and additive can not completely cut off contacting of aluminium powder pigment and corrosive medium fully; thereby additive is also very limited to the provide protection of aluminium powder pigment.The coating method is to coat one or more layers more transparent material on aluminium powder pigment surface, and this method be because can completely cut off contacting of aluminium powder pigment and corrosive medium, thereby can effectively protect aluminium powder pigment to avoid corroding.In addition, because coating layer is a transparency material, can keep the distinctive gloss of aluminium powder pigment preferably, therefore, the coating method is the most promising method in the present aluminium powder surface of pigments treatment process.But existing coating technology is difficult to form fine and close protective layer or protective layer on the aluminium powder pigment surface to be easy to come off from the aluminium powder pigment surface, and aluminium powder pigment is not had the better protecting effect.
