Abstract
The invention discloses a method for preparing flame-retardant iron oxide black granules. The method comprises the following specific steps of: dissolving polyethylene pyrrolidone, aluminum oxide and antimony trioxide into deionized water according to a certain weight ratio, so as to obtain viscous liquid; adding gas-phase white carbon black and simethicone to the obtained viscous liquid so as to carry out modification; and adding iron oxide black to a granulator for granulation while uniformly spraying the modified viscous liquid to iron oxide black powder, so as to form small iron oxide black granules, drying and sieving, thereby obtaining finished products. The iron oxide black granules prepared by the method have the characteristics of excellent temperature resistance, good acid and alkali resistance, strong light absorption, high coloring power, good compatibility, good dispersion and the like, and have huge market prospects.
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 Flame-retardant iron oxide black particle.
Background technology
Iron oxide black, molecular formula is Fe
3o
4, being black powder, is Fe
2o
3with the affixture of FeO, water insoluble, have magnetic, tinting strength and opacifying power are very high.Iron oxide black, as the one in iron pigment, due to its feature such as nontoxic, odorless, pollution-free, is widely used in phenolic antirust paint filler, heavy-duty coating priming paint etc. in building trade; For rubber, plastics painted time, have the effect that reinforcement is aging, simultaneously protect organism by the feature of ultraviolet degradation; In addition, also for artificial marble, pottery and cement flooring painted.But the phenomenons such as iron oxide black can fade at relatively high temperatures, variable color, heat-resistant stability is poor, thus limits 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 Flame-retardant 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 preparation method for Flame-retardant iron oxide black particle, comprises the following steps:
