Problems solved by technology

[0003] Although the existing color paste can play the functions of coloring and toning, the weather resistance is poor, and it is easy to fade for a long time, thereby affecting the use effect of the color paste; the existing Chinese patent document announcement number: CN109943152A discloses a nano-transparent oxidation Iron inkjet color paste, composed of iron oxide, dispersant, pH regulator, bactericide and water, calculated in parts by weight of raw materials: 30-35 parts of iron oxide; 15-20 parts of dispersant; 0.4-0.6 parts of pH regulator parts; 0.2-0.4 parts of fungicide; 45-55 parts of water, the raw material used in this color paste is relatively simple, and the weather resistance is poor, so further improvement is still needed

Abstract

The invention discloses an iron oxide color paste, which comprises the following raw materials by weight: 55 parts of iron oxide pigment, 10 parts of an impregnating compound, 3 parts of a nano slurry, 5 parts of an organic silicon defoamer, 10 parts of lithium magnesium silicate and 40 parts of deionized water. The impregnating compound added into the iron oxide pigment is formed by combining lauryl sodium sulfate, a silane coupling agent KH560 and other surfactants, a coupling agent and the like, and aims to enable dual amphoteric surface treatment on the iron oxide pigment so as to enhancethe surface treatment effect, and the added modified silicon dioxide can enhance the contact effect of the impregnating compound and the iron oxide pigment, thereby enhancing the treatment capacity.

Description

technical field [0001] The invention relates to the technical field of color paste, in particular to an iron oxide color paste and a preparation method thereof. Background technique [0002] Color paste is a semi-finished product made of pigment or pigment and filler dispersed in paint. The oily color paste with pure oil as the adhesive is called oily color paste. Resin color paste is called resin color paste with resin paint as adhesive. The pigment paste dispersed by adding surfactants in water as the medium is called water-based color paste. Because there are many types of paints, there are also many types of colorants. In order to better disperse pigments in the paint, a small amount of surfactant, zinc naphthenate, etc. is often added during the manufacturing process. [0003] Although the existing color paste can play the functions of coloring and toning, the weather resistance is poor, and it is easy to fade for a long time, thereby affecting the use effect of the...
