Problems solved by technology

[0003] There are many formulas contained in the paint, and the pigment in the paint is a relatively important formula, mainly to increase the color and luster of the paint. There are a wide range of paint pigments on the market, but the selection of the pigment is not scientific. Generally, the pigment itself has the ability to be afraid of high temperature. , non-refractory factors, so the pigments cannot be fixed for a long time, and the long-term use of the paint cannot be guaranteed

Abstract

The invention discloses flame-retardant indigo blue pigment special for oil paint and relates to the technical field of chemical engineering paint preparation. The flame-retardant indigo blue pigment comprises 15-25 parts of aluminum hydroxide, 15-25 parts of magnesium hydroxide, 8-10 parts of antimony oxide, 3-5 parts of zinc borate, 6-8 parts of titanium dioxide, 8-10 parts of ammonium polyphosphate, 6-8 parts of white carbon black, 7-10 parts of triethanolamine, 6-8 parts of glycerinum, 8-10 parts of sodium stearate and 8-10 parts of indigo blue coloring matter. The flame-retardant indigo blue pigment has the advantages that the pigment and the flame-retardant materials are correspondingly fixed in advance, the fire resistance is achieved, meanwhile, the advantages of the obtained paint are ensured, and the pigment is uniform in texture, fireproof, flame-retardant, lasting in color, environmentally friendly, free of toxicity, efficient, high in market value and convenient to use and popularize.

Description

technical field [0001] The invention relates to the technical field of preparation of chemical coatings, in particular to a special flame-retardant indigo pigment for paints and a preparation method thereof. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid thin film, the film formed in this way is commonly called coating film, also known as paint film or coating.” [0003] There are many formulas contained in the paint, and the pigment in the paint is a relatively important formula, mainly to increase the color and luster of the paint. There are a wide range ...
