Abstract

The invention discloses organic-inorganic hybrid nanometer film coating aluminum powder pigment and a preparation method and application thereof. The preparation method comprises the followings steps: by utilizing organic-inorganic hybrid technology and taking aluminum powder pigment as nuclear, firstly performing free radical polymerization on polymerisable carbon-carbon double bond reaction monomers and polymerisable carbon-carbon double bond organosiloxane; and bonding the obtained polymer and ethyl orthosilicate with the surface of the aluminum powder pigment in a hydrolysis mode, and further coating a layer of organic-inorganic hybrid nanometer film on the surface of the aluminum powder. On the basis of maintaining the lustrousness of the aluminum powder, the prepared organic-inorganic hybrid nanometer film coating aluminum powder pigment has excellent compatibility with resin and good acid and alkaline resistance properties, simultaneously well solves the problem of 'powder falling' when the conventional aluminum powder and single-layer or two-layer costing aluminum powder pigment are applied to metallic coatings, and provides a foundation for applying modified aluminum powder pigment and developing high performance metallic coatings.

Description

technical field [0001] The invention relates to the field of organic-inorganic hybrid technology, in particular to an organic-inorganic hybrid nano-membrane-coated aluminum powder pigment and its application technology. Background technique [0002] In recent years, with the increasing demand for aluminum silver paste and protective coatings in the fields of finishing and decoration, aluminum powder pigments have received extensive attention. High gloss, strong adhesion and corrosion resistance have become the key to measure the performance of aluminum powder pigments. In order to obtain the above-mentioned high-performance pigments, it is necessary to modify the surface of the aluminum powder. At present, the commonly used methods are all based on chemical protection methods, which are mainly divided into additive methods and coating methods. The additive method is to physically mix additives on the surface of aluminum pigment particles to form a protective layer on the o...
