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.

Abstract

The invention discloses a luminous aluminum pigment for water-based paint and a preparation method of the luminous aluminum pigment. The luminous aluminum pigment for water-based paint is prepared from the following raw materials in parts by weight: 56-72 parts of modified aluminum power, 12-18 parts of diglycolamine, 4-8 parts of glycidyl tert-carbonate, 16-22 parts of calcium molybdate, 1-2 parts of 2-methyl-4-isothiazolin-3-one, 2-4 parts of stannous pyrophosphate, 10-15 parts of tripropyl powder, 1-2 parts of inositol hexaphosphat, 3-6 parts of sodium caseinate, 2-4 parts of zinc oxide, 1.5-2.5 parts of PPG-m-PEG-n Tallowaminopropylamine, 1-2 parts of parachlormetaxylenol and 2.5-4.5 parts of urotropin. The luminous aluminum pigment prepared has excellent comprehensive performance, has excellent covering power, waterproof performance, heat performance and weather fastness, has very good dispersity in a water-containing system and can be widely used in various types of water-based paint.

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 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 ...
