Highly dispersed luminous aluminum pigment and preparation method thereof

Abstract

The invention discloses a highly dispersed luminous aluminum pigment and a preparation method thereof. The highly dispersed luminous aluminum pigment is prepared from the following raw materials in parts by weight: 78-96 parts of modified aluminum powder, 18-24 parts of an acrylic acid-hydroxypropyl acrylate copolymer, 7-13 parts of ethynyl cyclohexanol, 2-4 parts of ethoxylated methyl glucose dioleate, 5-10 parts of silicone powder, 2-3 parts of sodium lauryl monoethanolamide sulfate, 3-4 parts of glycol distearate, 6-12 parts of calcium carbonate powder, 2-3 parts of diaminodiphenylmethane, 4-8 parts of low molecular weight polypropylene, 2-4 parts of triethanolamine alginate, 3-5 parts of behenamide and 5-10 parts of polyvinyl acetate. The highly dispersed luminous aluminum pigment is good in dispersity, excellent in intersolubility with organics, excellent in temperature tolerance, chemical resistance and outdoor weather resistance, and widely suitable for a plurality of water-based systems such as water-based inks, water-based plastic coatings, water-based building coatings and water-based paints.

Description

technical field [0001] The invention discloses a highly dispersed luminescent aluminum pigment and a preparation method thereof, belonging to the field of aluminum pigments. Background technique [0002] Aluminum pigment, also known as aluminum powder pigment, refers to metal aluminum powder or aluminum paste with scaly particle structure, bright metallic luster and other pigment characteristics. It is an important variety of metal pigments, mainly used in paint, printing Production of paints, paints, plastic materials, etc. In recent years, with the continuous improvement of my country's economic level and the rapid development of the modern water-based paint industry, people have a deeper understanding and higher requirements for the quality of decoration. Therefore, the demand for aluminum pigments has gradually increased. requirements have also become more stringent. Not only is it required to have a unique luminous effect, but it is also required to have good water...

AI Technical Summary

Problems solved by technology

Not only is it required to have a unique luminous effect, but it is also required to have good water resistance, dispersibility and compatibility. However, the aluminum pigments currently on the market generally do not have luminous properties, and they have high polarity and poor water resistance during use. , It is easy to be hydrolyzed in water, which reduces the luminous brightness, short life, poor dispersion in water-based systems, poor compatibility with organic matter, and precipitation and agglomeration after long-term storage, which limits its further application.
