Fire-retardant black iron oxide pigment

Abstract

The invention relates to an iron oxide pigment, in particular to a fire-retardant black iron oxide pigment. The pigment provided by the invention is prepared from the following raw materials in parts by weight: 280 to 300 parts of black iron oxide, 5 to 8 parts of Na-montmorillonite, 1 to 2 parts of a silane coupling agent KH-5501-2, 3 to 5 parts of antimonous oxide, 4 to 6 parts of pyrophillite, 1 to 2 parts of calcium stearate, 3 to 5 parts of polyethylene wax, 1 to 2 parts of sodium dodecyl sulfate, 10 to 12 parts of coal ash, and 4 to 5 parts of an assistant. According to the pigment provided by the invention, the raw materials such as the polyethylene wax and the sodium dodecyl sulfate are used for improving the surface activity of a black iron oxide power; thus the distributing in a base material is more uniform, and the probability of sediment is low. The added raw materials such as Na-montmorillonite, antimonous oxide and pyrophillite ensure the black iron oxide pigment has the characteristics of fire resistance, flexibility, abrasion resistance, watertightness and damp resistance, and the like; during actual use, the fire-retardant black iron oxide pigment is safe and reliable, the covering power is large, and the application value is extremely high.

Description

technical field [0001] The invention relates to an iron oxide pigment, in particular to a flame-retardant iron oxide black pigment and a preparation method thereof. Background technique [0002] Iron oxide pigments are a kind of widely used inorganic pigments. They are widely used in construction, coatings, inks, ceramics, cosmetics and other industries. It also has the advantages of wide color spectrum, strong coloring power, non-toxicity and low price. At present, the iron oxide series pigments used in the market mainly include iron oxide red, iron oxide black, iron oxide yellow and orange, brown, green, etc. Composite pigments such as iron oxide are widely used. However, in the actual use process, there are problems such as easy agglomeration, difficulty in uniform dispersion in the medium, and insufficient bright color. In order to obtain better performance, it is often necessary to carry out surface treatment and performance improvement on iron oxide pigments. , in ord...

Problems solved by technology

[0002]Iron oxide pigments are a kind of widely used inorganic pigments, which are widely used in construction, paint, ink, ceramics, cosmetics and other industries. It not only has stable chemical properties, but also Acid and alkali resistance, light resistance and heat resistance, high tolerance to dry and wet, cold and hot climates, and also has the advantages of wide color spectrum, strong tinting power, non-toxic and cheap, etc. The iron oxide series pigments currently used in the market mainly include iron oxide Red, iron oxide black, iron oxide yellow, and orange, brown, green and other composite pigments are widely used. However, in the actual use process, there are problems such as easy agglomeration, difficulty in uniform dispersion in the medium, and insufficient bright color. In order to obtain better In terms of performance, it is often necessary to carry out surface treatment and performance improvement on iron oxide pigments to improve production and application performance and increase product added value
