Luminous aluminum pigment for water-based paint and preparation method of luminous aluminum pigment

Abstract

The invention discloses a luminous aluminum pigment for a water-based paint and a preparation method of the luminous aluminum pigment. The luminous aluminum pigment is prepared from the following raw materials in parts by weight: 50-70 parts of modified aluminite powder, 2-3 parts of isostearyl glucoside, 10-15 parts of polyvinylpyrrolidone, 3-5 parts of phenylsulfonyl trihydroxymethylaminomethane, 2.5-4.5 parts of betaine salicylate, 2-3 parts of zinc isoocatanoate, 5-10 parts of dibutyl maleate, 60-80 parts of tung oil, 15-25 parts of talcum powder, 5-10 parts of polyethylene micronized wax, 4-8 parts of hydroxypropyl xanthan gum powder, 2-4 parts of pentachlorophenol and 1-3 parts of p-methoxy ethyl cinnamate. The luminous aluminum pigment prepared by the method has excellent water resistance, weather fastness and acid and alkali resistance, is easily dispersed in a water-based paint, is easily dissolved together with a water-based paint system, is wide in application range, and has a wide application prospect.

Description

technical field [0001] The invention discloses a luminescent aluminum pigment for water-based paint 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 coatings, printing Production of inks, 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...

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 paint, poor compatibility with organic matter, and precipitation and agglomeration after long-term storage, which limits its further application.
