Description
One, affiliated technical field: chemical industry of inorganic salt field
Two, background technology:
Zinc phosphate Zn
3(PO

2XH
2O (x is 0,2,4) is mainly used in environmental friendly, anti-corrosive pigment, ferrous metal phosphatization, is used for glass, enamel, pottery etc. on a small quantity, at present industrialized preparing process has two classes, and is as follows:
1, neutralisation
Add dilute phosphoric acid neutralization, slaking, filtration, drying in the Zinc oxide water slurries and get.
Production technique is complicated.The ratio of the amount of substance of used zinc oxide and phosphoric acid is 3: 1, and zinc oxide can not transform fully.Zinc oxide and product phosphate dihydrate zinc are almost insoluble in water, and this reaction essence is a precipitation conversion reaction.Must power consumption again consuming time with traditional indirect heating method.
2, double decomposition
Alkali metal phosphate and soluble zinc salt react at hot aqueous phase, adjust the pH value, and filtration, washing, fragmentation, drying make.
Wherein: M is a basic metal.
In neutralisation, raw material zinc oxide and phosphoric acid are technical grade product, and price is higher, and production cost is higher.In double decomposition, though the employing soluble zinc salt is a raw material, unit weight zinc price is low than zinc oxide, is raw material owing to adopt the technical grade alkali metal phosphate, and cost is also higher.
English Patent BP 962182 discloses a kind of zinc phosphate production method, and adopting soluble zinc salt and phosphoric acid salt is raw material, and replacement(metathesis)reaction is carried out in two steps, produces four water zinc phosphates, and this method must be used purer raw material, the production cost height.
U.S. Pat-A 4294808 discloses a kind of method from zinc oxide and phosphoric acid production zinc phosphate, zinc oxide at first in water by means of spiral pump under the condition of 3000rpm～10000rpm, circulate dispersion, fragmentation, add phosphoric acid further reaction, slaking under spiral pump circulation dispersion condition again, after filtration, the dry product that gets.This technology belongs to neutralisation, though speed of reaction and production efficiency are higher, technology is simple, must use higher zinc oxide of purity and PHOSPHORIC ACID TECH.GRADE to be raw material, and the raw materials for production cost is higher.
It is the method for raw material preparation of zinc phosphate with purification of wet process phosphoric acid and zinc oxide that Chinese patent 1164508 (publication number) discloses a kind of, it is characterized in that used zinc oxide is the inferior rudimentary zinc oxide of inexpensive matter, zinc oxide content is 50%～95%, through acid (mixing acid of sulfuric acid and small amounts of phosphoric acid) dissolving, zinc change over to liquid phase and through purify must contain zinc 10%～18% after concentrating solution again with contain P
2O
5The mixed organic solvents of 11%～17% (and containing butanols＞60%, TBP＜40%) is pressed P mutually
2O
5React with the stoichiometric of Zn.There are three shortcomings in this method: the one, solution behind the sour molten zinc oxide is because impurity exists, or this solution must be further purified, or the product foreign matter content is higher, and purity is low; The 2nd, sour dissolved oxygen zinc solution must concentrate, and consumes more energy; The 3rd, reaction generates wet product and contains organic solvent, also will consume than macro-energy if organic solvent reclaims, and because of the TBP boiling point is higher than zinc phosphate two water thing dehydration temperaturres, product is difficult to crystallization control water number amount.
Chinese patent 1460637 (publication number) discloses employing low-heat solid state reaction direct synthesis technique, concrete technology is, with zinc salt powder, inorganic phosphate powder is basic raw material, add template, under 15～150 ℃, non-pressurized condition, mix the back and grind, then allow the reaction mixture insulation leave standstill, wash the inorganic salt by-product of solubility in the dereaction mixture then with water, filter, oven dry obtains nano level zinc phosphate crystal after the pulverizing.Above-described synthesis of nano zinc phosphate crystalline method, its proportioning raw materials is: zinc salt: inorganic phosphate=1.0～2.5: 1.0 (mol ratios), template then account for 0.1～15% of entire reaction thing weight.This technology essence is to prepare zinc phosphate with replacement(metathesis)reaction, and two kinds of material purities are had relatively high expectations, and production cost is also higher.
Three, summary of the invention
1, the objective of the invention is to overcome the existing raw materials used deficiency of producing, providing a kind of is raw material from fertilizer grade ammonium phosphate, prepares the method for zinc phosphate through impurity and purification, metathesis, the wide material sources of fertilizer grade ammonium phosphate, cheap, and production cost is low.
2, invention is finished according to the following steps
1), raw material is the fertilizer grade ammonium phosphate salt, soluble zinc salt.The fertilizer grade ammonium phosphate salt comprises monoammonium phosphate (MAP), diammonium phosphate (DAP); Soluble zinc salt comprises zinc sulfate, zinc chloride, zinc nitrate;
2) technological process of the present invention
(1), ammonium phosphate prepares ammonium phosphate solution
It is in 1～2 times 50 ℃～80 ℃ the water that 1 part of fertilizer grade ammonium phosphate is dissolved in weight ratio, and 25～60 minutes after-filtration of insulation ageing, the filtering and removing insoluble impurities.Filter residue is with 50 ℃～80 ℃ hot washes washing 1～2 time, wash water and filtrate merge ammonium phosphate solution, filter residue can be used as the fertiliser production raw material;
(2), zinc solution preparation
Soluble zinc salt under agitation is dissolved in 50 ℃～80 ℃ hot water, and heat filtering is removed the mechanical impurity that wherein may contain, and makes the zinc solution of 20wt%～45wt%;
(3), replacement(metathesis)reaction
In ammonium phosphate solution that makes and zinc solution, phosphate anion and zine ion mol ratio are 0.7～1: 1 ratio, two kinds of solution that make are added mixing in the container of being with stirring, keep 50 ℃～80 ℃ of solution temperatures, adjust between the pH of mixed value 6.5～8.5 with alkali lye, (alkali lye comprises sodium hydroxide solution, potassium hydroxide solution, ammoniacal liquor), slaking is sent out and is answered 10～20 minutes after-filtration, filter cake obtains wet zinc phosphate with 50 ℃～80 ℃ hot washes of 2～5 times of its weight 2～3 times;
(4), drying
Wet zinc phosphate in 90 ℃～110 ℃ dryings 10～30 minutes, obtains the zinc phosphate product under normal pressure.
3, the advantage that compared with prior art had of present technique
1, adopting fertilizer grade ammonium phosphate is raw material, and it is wide, cheap to have a source, and production cost is low.
2, make because of adopting raw material fertilizer grade ammonium phosphate and zinc sulfate to be wet method, thereby this technology belongs to energy-saving technology.
