U.S. Pat 2,369,261 disclose a kind of manufacture method that contains chromic oxide pigment with wet production, main powder with chromic oxide (chromic salt, sodium sulfate, Sodium chromate, dichromate) barium sulphide, barium sulfate, sodium sulfate, sodium hydroxide, yellow soda ash, potassium hydroxide, china clay, shale stone flour, chromium hydroxide, bariumchloride, after the chemical treatment drying, roasting again makes the veridian that contains chromic oxide.Its advantage is that product colour is bright-coloured, and strong coloring force, fineness are thin, and shortcoming is a polluting environment of manufacturing process, complicated operation, and process time is long, the manufacturing cost height.
CN88103695.1 disclose a kind of adopt as kaolin families contain silicon components, chromic oxide, zinc oxide and borax, pass through high-temperature roasting and obtain inorganic green pigment.Its advantage is that manufacturing processed is free from environmental pollution, and technical process is short, and is simple to operate, color category is many, shortcoming is that tinting strength is low, and this is an important deficiency for pigment, its secondary zinc oxide volatilization point is low, scaling loss is big, and the zinc oxide after the volatilization is poisoned big, and the fusing point of borax is extremely low, very easily lump after the roasting, unfavorable to discharging and grinding.
The objective of the invention is to propose a kind of manufacture method of improved inorganic green pigment, compare with CN85108554A, the pigment that the inventive method draws is except the whole advantages that possess CN85108554A, its many shortcomings have also been overcome, do not need to use reductive agent as the present invention, can open wide roasting, the normal temperature charging, do not limit drop temperature, maturing temperature is 750-980 ℃ lower, roasting time only 1-3 hour, color category except emerald green, green, the shallow multiple color such as grass green of grass green in addition, chrome green, dish.
With US2,369,261 compare, and manufacturing processed of the present invention is pollution-free, and technical process is short, processing ease, and cost is low, and color category is many.
Compare with CN88103695.1, the present invention and its something in common are: no three wastes public hazards, and technical process is short, and simple to operate, pigment type is many.The places different with it are: the former is simpler for recipe ratio, and cost is lower, and color and luster is more bright-coloured, and strong coloring force, overcomes the murder by poisoning of the volatilization of zinc oxide in its roasting to the people, has overcome in its roasting the easily shortcoming of caking.
In a word, the objective of the invention is to propose a kind of improved inorganic green pigment manufacture method, its color category is many, as chrome green, dish is green, grass green and emerald green etc.Lovely luster, good heat resistance, constant erosion resistance steady in a long-term is good on the high temperature, fast light photograph well, technical process is short, processing ease, no three wastes public hazards in the production, cost is lower.
Invention is achieved in that the manufacture method of inorganic green pigment: in hard kaoline, add chromium sesquioxide, and with soda and/or sodium salt as auxiliary agent, obtain veridian through high-temperature roasting, its cooperation (weight) is than being: hard kaoline 45-82%, chromium sesquioxide: 5-35%, soda and/or sodium salt: 4-25%, 750 ℃-980 ℃ of maturing temperatures, roasting time 1-3 hour.The cooperation of soda and/or sodium salt (weight) is than being: caustic soda 5-25% or soda ash 8-25% and/or yellow soda ash 4-20%.
The synthetic of pigment united two into one with dyeing, both having made full use of the raw material that does not play a role during pigment is synthetic forms, as aluminum oxide, calcium oxide, magnesium oxide, titanium oxide, reduced the consumption of somewhat expensive chromium sesquioxide in the synthetic dyestuff again widely, thereby further reduced cost.
The silicon-containing material that uses mainly is a hard kaoline, refers to contain silica volume greater than the kaolin more than 60%, and iron level is less than 0.5%.Two change the silicone contents big kaolin of healing, effect better, dioxide-containing silica is less than 60% kaolin, effect is bad.
Soda or sodium salt are the supply source of sodium in the synthetic dyestuff sodium silicic acid chromium, play a part again to quicken in dyeing course and strengthen pigment and matrix bond, use this raw material, make pigment and basal body binding force after the dyeing strong, and tinting strength is good.
The color of inorganic green pigment, kind can arbitrarily be adjusted and change, and generally change the content of chromium sesquioxide, only can change the depth of color, and the content of chromium sesquioxide is big, and green intensity is dark, and the content of chromium sesquioxide is few, and then green intensity is shallow.Change sodium salt or the kind of soda and the kind that content can change color, get the dish delivery green as adding caustic soda.Caustic soda and yellow soda ash be used obtain emerald green.Obtain grass green with yellow soda ash.Obtain the chrome green look with soda ash.The consumption of sodium salt or soda is bigger, and color is darker.But consumption easily lumps in roasting too greatly, the maturing temperature height, and the deflection dish is green, emerald green, grass green.Maturing temperature is low, and the deflection inscription is green.But with proportioning by comparison, the component of pigment is a major influence factors.
