Abstract
The invention discloses a method for preparing high-dispersion black iron oxide particles. The method comprises the following concrete steps of: dissolving polyethylene glycol, methylcellulose and span-80 into deionized water according to a certain weight ratio to obtain viscous liquid; adding nano silica and carbon black to the prepared viscous liquid to modify; feeding black iron oxide to a pelletizer to pelletize; evenly spraying the modified vicious liquid on black iron oxide powder to form black iron oxide granules; drying and screening to obtain the product, namely nano-silica and 1.5-2.5% of stearic acid monoglyceride.
Description
Technical field
The present invention relates to a kind of preparation method of iron oxide black, be specifically related to a kind of preparation method of polymolecularity iron oxide black particle.
Background technology
Iron oxide black, molecular formula are Fe
3O
4, be black powder, be Fe
2O
3With the affixture of FeO, water insoluble, have magnetic, tinting strength and opacifying power are very high.A kind of as in the iron pigment of iron oxide black because it is nontoxic, do not have characteristics such as smell, pollution-free, is widely used in phenolic antirust paint filler, heavy-duty coating priming paint etc. in the building trade; When being used for rubber, plastics painted, the aging effect of reinforcement is arranged, protect organism by the characteristics of ultraviolet degradation simultaneously; In addition, also be used for the painted of artificial marble, pottery and cement flooring.But phenomenons such as iron oxide black can fade under comparatively high temps, variable color, heat-resistant stability is poor, thereby has limited the use range of iron oxide black.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of polymolecularity iron oxide black particle, improve the high-temperature stability of iron oxide black.
The technical solution used in the present invention is as follows:
A kind of preparation method of polymolecularity iron oxide black particle may further comprise the steps:
(1) take by weighing polyoxyethylene glycol, methylcellulose gum and Arlacel-80 by weight 3-5:2-3:1 and add in the 10-15 times of deionized water, heating in water bath ultra-sonic dispersion 20-30 minute, gets viscous liquid to 55-60 ℃;
