Description
Technical field
The present invention relates to a kind of Inorganic Chemicals cuprous oxide powder and preparation method thereof, more particularly to suitable for applying
Material and electronic material cuprous oxide powder and preparation method thereof.
Background technology
Cuprous oxide is a kind of red or yellow industrial chemicals and product, is the important p-type semiconductor material of a class, generally
The octahedral cubic system cuprous oxide powder of crystal type is rendered as red or orange-yellow.But cuprous oxide is sometimes because different systems
Different colors can be presented from different grain sizes in standby means.Cuprous oxide heat endurance is very strong（Decomposition temperature 1800
oC）, cuprous oxide is highly stable in the dry air of room temperature, but is easily oxidized in malaria the oxidation of black
Copper, cuprous oxide is also easily reduced into metallic copper.
Cuprous oxide powder purposes is widely.Coatings industry is used as marine antifouling priming paint, coating, bactericide, copper ion
In the thin layer of coating surface formation toxic solution, it is possible to decrease the activation that apoenzyme is metabolized to biological life in living organism, from
And reach antifouling purpose.Glass industry is used as red glass and red enamel colouring agent.Agricultural is used as bactericide, feed addictive；
Agricultural chemicals is can be used as, is the specific pesticide for the false smut for preventing and treating paddy rice.Cuprous oxide is due to semiconductor property, can be used as
Rectifier material, photoelectron transition material, ballast material, the electrode etc. of electronics gas sensor limit and battery.Cuprous oxide
It is used as the additive of anti extreme pressure heavy load grease in machinery industry；It is used as heating medicament on medical health care products and in ring
Guarantor field is used for catalytic oxidation of sulphur dioxide, it is also possible to make solar cell.Cuprous oxide also acts as plastic and glass table
Face is material modified and organic industry catalyst etc., is also with a wide range of applications in terms of photocatalysis.
The preparation of cuprous oxide will be more ripe, and the conventional cuprous oxide in the country is mainly dry method, wet method and electrolysis
Deng.Dry method is also known as sintering process or solid phase method, is exactly pre-mixed solid copper powder and cupric oxide powder, is heated in incinerator
To 800 ~ 900oC high-temperature calcinations reaction.Energy consumption is for example, reduced, patent CN104150522A is disclosed under 600oC in electricity roasting
The method that confined reaction prepares cuprous oxide powder in 6 hours in stove.But, reducing agent is made with copper powder and consolidated with solid oxidation copper
Phase reaction, which exists, reacts the inherent defect such as uneven, not thorough, thus obtained cuprous oxide powder purity is relatively low, past in product
It is past to contain copper and cupric oxide impurity, it is difficult to remove.This result is mainly unbalanced by sintering sufficiently complete or course of reaction
Cause.It is uncontrollable also to there is granularity in the cuprous powder of dry oxidation（Depending on the granularity of raw material copper powder and cupric oxide powder）, it is easy to
It is hardened, the shortcomings of be difficult to scattered.Meanwhile, the dry technology for production production cycle is long（72 h）, equipment complexity, high energy consumption, yield it is inclined
It is low.Therefore, roasting method prepares cuprous oxide powder developed country receives very big limitation abroad, although to prepare oxidation sub- for the method
Copper powders yield accounts for 80 more than % of China's cuprous oxide total amount.
In recent years, the cuprous oxide powder obtained by wet-chemical reducing process is because its particle diameter is small, purity is high, dispersive property is good,
Increasingly paid attention to.Current common preparation method can be divided into sulphite, azanol, rongalite, copper according to the difference of reducing agent
Powder, zinc powder, hydrothermal reduction method etc. are several, are all to reduce the copper ion in solution and obtain cuprous oxide.For example, patent
CN104591257A discloses one kind with gelatin/neopelex（Mass ratio 1:1）For compounding dispersant, sodium sulfite
Under conditions of reducing agent, reaction temperature 60-100oC, the method for preparing the micro-nano cuprous oxide powder of cube.Patent
CN1305772C disclose one kind by inhibitor of polyvinylpyrrolidone, lauryl sodium sulfate be dispersant, hydrazine hydrate be
Reducing agent and pH value are the method for preparing the nano cuprous oxide powder end that particle diameter is 10 ~ 100 nm under the conditions of 6.8 ~ 7.2.
Patent CN103842295B discloses a kind of chemical reduction method using glucose as reducing agent and prepares average primary particle diameter less than 0.4
The method of μm cuprous oxide.And patent CN102190327A uses copper sulphate, copper chloride, copper nitrate, hydroxide copper sludge and oxygen chlorine
Change the reducing agent reduction reactions such as the copper-containing compounds such as copper and metallic copper into stannous chloride, then it is sub- with sodium hydroxide reaction generation oxidation
Copper.Sum it up, although wet method is partially improved to dry method, there is also once through yield is low, production cost is high, environment
Pollute, consumption is high and is difficult to the shortcomings of industry is amplified.For example on earlier industry prepare cuprous oxide powder using method of glucose reduction
End, because cost is high, deficiency in economic performance, is gradually calcined method in the eighties in last century and is replaced.Although hydrothermal reduction method is well
Overcome high temperature and prepare inevitable reunion, its product has powder thin (nanoscale), purity height, good dispersion, crystal formation good
And the advantages of controlled shape, but hydrothermal reduction method needs the closed container in HTHP to be reacted, and there is industrial amplification
Difficulty is big, high energy consumption and the high problem of production cost.
Electrolysis because with production procedure is short, simple to operate, energy consumption and production cost is relatively low, substantially pollution-free, product matter
Amount is excellent, the features such as be suitable for industrialized production, and developed country is rapidly developed abroad in recent years, at present in Japan, beautiful
The country such as state, Germany cuprous oxide powder generally uses electrolysis technique.The reaction principle of electrolysis is as follows：
Anode reaction（The dissolving of copper）
Cu+Cl- → (CuCl-1) adsorbs (1)
(CuCl-1) absorption+(n-1) Cl--e → (CuCln1-n) (n=2,3) (2)
Cathode reaction（The generation of hydrogen）
2H2O + 2e → H2 ↑ + 2OH- (3)
Hydrolytic precipitation reacts
CuCln1-n + 2OH- → Cu(OH)2- + nCl- (4)
2Cu(OH)2- → Cu2O + H2O + 2OH- (5)
During electrolytic preparation cuprous oxide, it is in largely spongiform metallic copper that negative electrode, which can be produced, causes cuprous oxide matter
Amount is inferior.Industrially, solve negative electrode copper sponge and separate out problem, generally using plus barrier film or exacerbation chromate or chromate come
Suppress copper sponge to separate out in negative electrode.But, in diaphragm-free electrolysis method there is meeting polluted water in chromic salts in waste water.Meanwhile, at present
Electrolyte temperature is 90 ~ 95oC in diaphragm-free electrolysis method technique, reaction engineering, and temperature is too high, one side electrolyte evaporation loss
Increase, makes working condition severe, causes labor intensity to increase, on the other hand, and energy expenditure is excessive, and product cost rises；And
Because electrolyte boiling causes bottom of electrolytic tank bubbling, the cuprous oxide of trench bottom is taken to electrolyte surface, so that oxidation
The cuprous cupric oxide for being oxidised with air to black, product quality is affected.Therefore, how to reduce electrolysis and prepare oxidation Asia
The reaction temperature of copper and chromic acid salt additives are replaced to be core problem that state's internal electrolysis runs into using environmental-protection additive.
