Problems solved by technology

However, the existing various aluminum pigments have poor corrosion resistance and can be corroded by chemical reactions with water, oxygen, acids, alkalis and other substances. Products coated with them are usually corroded after 3 years of use. If it falls off, the surface of the product will be dull, or even lose its metallic luster, and it needs to be repainted, which increases labor and cost input

Abstract

The invention discloses a preparation method of a corrosion-resistant aluminum pigment. The corrosion-resistant aluminum pigment is prepared from the following raw materials in parts by weight: 70-75 parts of aluminum paste, 12-15 parts of a first liquid mixture, 16-18 parts of a second liquid mixture, 100-130 parts of a third liquid mixture and 5-10 parts of a fourth liquid mixture. The preparation method of the corrosion-resistant aluminum pigment comprises the following steps of: (1) preparing raw materials; (2) preparing a first cladding layer; (3) separating and purifying; (4) preparing a second cladding layer; and (5) separating and purifying the finished material. The preparation method of the corrosion-resistant aluminum pigment is easy and convenient to operate and is easy to implement, and the prepared corrosion-resistant aluminum pigment prepared by adopting the preparation method is a double-clad modified aluminum pigment and has a thin and uniform cladding layer, has a little influence on the metallic luster of an aluminum sheet, has the advantages of corrosion resistance, oxidation resistance and water resistance, is well compatible with a polymer resin, can be dispersed in a coating uniformly, has good durability and has a broad application prospect.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a method for preparing corrosion-resistant aluminum pigments. Background technique [0002] Aluminum pigments are widely used in the fields of industrial coatings, automotive coatings, printing inks and plastic processing because they can reflect visible light, infrared light and ultraviolet light, and have a unique metallic glitter effect. They are an important metallic pigment. However, the existing various aluminum pigments have poor corrosion resistance and can be corroded by chemical reactions with water, oxygen, acids, alkalis and other substances. Products coated with them are usually corroded within 3 years of use. If it falls off, the surface of the product will be dull, or even lose its metallic luster, and it will need to be repainted, which will increase labor and cost input. Contents of the invention [0003] The technical problem mainly solved by the present invention is ...
