Wherein modified oxidized iron oxide black is obtained by the raw material of following weight parts: ferrous sulfate 40-50, imidazoline quaternary ammonium salt 0.3-0.5, citric acid 0.3-0.5, dimethyl silicone oil 0.2-0.4; Citric acid is added to the water by solid-liquid weight ratio 1:100-1:150 to dissolve completely by the preparation method of described modified oxidized iron oxide black, and all the other raw materials 800-1000r/min added outside sulfuric acid ferrous iron stirs 5-10min, obtains modification liquid; Ferrous sulfate is added to the water the solution being mixed with 150-200g/L, in solution, adds described modification liquid, pH regulator is stirred to 7-8, pass into oxygen to be oxidized under 80-90 DEG C of condition, react the iron oxide black of terminating in rear separating slurry, through washing, oven dry, pulverize, to obtain final product.
Containing a preparation method for the black iron oxide pigment of bamboo charcoal powder, comprise the following steps:
(1) grinding after modified oxidized iron oxide black, bamboo charcoal powder, nano-calcium carbonate and tripoly phosphate sodium STPP mixing evenly, is then added the water of 2-3 times of weight, obtains iron oxide black slurries after dispersed with stirring;
(2) water glass is added to the water the solution being mixed with 20-30g/L, then be added dropwise in the iron oxide black slurries in (1) and stir, by pH regulator to 8-8.5, then ageing 2-3h, filters, washs and obtain coated with silica iron oxide black after drying;
(3) Diisopropyl azodicarboxylate is dissolved in a small amount of toluene obtains initiation solution; Coated with silica iron oxide black in (2) and vinylbenzene to be added jointly in appropriate dehydrated alcohol and to be uniformly dispersed; pass into nitrogen protection and temperature is adjusted to 70-80 DEG C; drip initiation solution reaction 2-4h; mix with all the other raw materials after filtration, washing and grind evenly, after drying, namely obtaining the black iron oxide pigment containing bamboo charcoal powder.
Bamboo charcoal powder can absorb the various obnoxious flavoures in air, makes room air be purified and become pure and fresh, has deodorizing, the effect that degerming, adsorption removal is harmful to peculiar smell.
Advantage of the present invention is:
The present invention utilizes the properties-correcting agent such as imidazoline quaternary ammonium salt and citric acid to carry out modification to iron oxide black, plays good dissemination in particle formation, effectively improves the tinting strength of iron oxide black, has corrosion inhibition simultaneously; Then carry out silicon-dioxide and vinylbenzene double-coated, both improved the temperature tolerance of black iron oxide pigment, make it have again good erosion resistance, and its dispersing property in the base can be improved; Composite simultaneously by with raw materials such as bamboo charcoal powder, not only tinting strength is high to make the black iron oxide pigment that obtains, temperature tolerance and weathering resistance good, be easy to dispersion, good processability, also have good deodorizing, degerming, adsorption removal is harmful to the effects such as peculiar smell, use properties is good.
