Abstract
The invention relates to a method for preparing zinc stannate under a vacuum condition, and belongs to the technical field of chemical engineering production. The method comprises the following steps: firstly uniformly mixing stannic oxide and zinc oxide powder according to the mole ratio of 1: 2-1: 5 to obtain mixed powder, and pressing the mixed powder under the pressure of 2-20MPa to obtain pellets; roasting the pressed pellets under the conditions that the vacuum degree is 1 and the temperature is 900-1,400 DEG C for 20-70 minutes, and cooling to obtain the zinc stannate. According to the method, the problems that the technology for industrially producing the zinc stannate is cmplicated and the pollution to the environment is high in the prior art can be solved; in the process of preparing the zinc stannate, the vacuum condition is required, and the environment pollution is low.
Description
Technical field
Prepare the method for zinc under the present invention relates to a kind of vacuum condition, belong to chemical production technical technical field.
Background technology
Zinc as the fire retardant in plastics industry and smog inhibitor, is mainly the environmentally friendly machine that fire retardant made by alternative antimonous oxide, has the advantages such as nontoxic, safe, easy use.Zinc excellence fire-retardant and suppress the characteristic of being fuming to be used to PVC(rigidity and soft), vibrin, polyester paint, neoprene latex, polyethylene, many vinegars amine (nylon 6 and nylon66 fiber), epoxy resin, ethylene vinyl acetate copolymer production.
In the 41st volume the 5th phase " sluggish precipitation prepares the research of zinc and zinc coated nano calcium carbonate " that inorganic chemicals industry is published, hydroxyl stannate sodium, zinc chloride, zinc oxide, potassium hydroxide, urea massage ear proportioning 1:1:7:10 are taken, add in three-necked bottle, constant-temperature condensation back flow reaction 6h at 85 DEG C.Reaction end deionized water wash suction filtration, filter cake after ultrasonic disperse with propyl carbinol component distillation, gained powder is dried overnight in 50 DEG C of vacuum drying ovens, obtains zinc hydroxyl stannate.And calcine to obtain zinc at a certain temperature.The method have passed through constant-temperature condensation, ultrasonic disperse, component distillation and high-temperature calcination Four processes, and to prepare the flow process of zinc comparatively complicated.
Summary of the invention
For above-mentioned prior art Problems existing and deficiency, under the invention provides a kind of vacuum condition, prepare the method for zinc.The invention solves industrial production in prior art and prepare zinc complex process, problem big for environment pollution, under the present invention requires vacuum condition in preparation zinc process, environmental pollution is little, and the present invention is achieved through the following technical solutions.
Prepare a method for zinc under vacuum condition, its concrete steps are as follows:
Step 1, first tindioxide, Zinc oxide powder being mixed according to mol ratio 1:2 ~ 1:5 and obtain mixed powder, is then that 2 ~ 20Mpa is pressed into pelletizing by mixed powder at pressure;
Step 2, pelletizing that step 1 is pressed into vacuum tightness be 1, temperature be 900 ~ 1400 DEG C of conditions under roasting 20 ~ 70min, can zinc be prepared after cooling.
The diameter of the pelletizing be pressed in described step 1 is 3-5cm.
The invention has the beneficial effects as follows: the present invention is due under vacuum, and produce what waste gas hardly, environmental pollution is little, and only powder compact heating just can need be produced zinc in process, technological process is simple.
