Description
Technical field
The present invention relates to a kind of preparation method of low-corrosiveness deicing salt, belong to deicing salt preparing technical field.
Background technology
Deicing salt also known as changes cryosel, road antifreezing agent, is mainly used for winter airport, highway, square, parking lot, railway, city
Snow removing and antifreeze effect are played in city street etc., its component is based on the salts such as sodium chloride, calcium chloride, magnesium chloride.Due to deicing salt
Have the advantages that easy to use, moderate, in addition to being widely used except big city, many small and medium cities also gradually tend to be large quantities of
Amount uses.But most common deicing salt is mostly villaumite type deicing salt at present.Wherein sodium chloride due to source is wide, price is low,
Dosage is big, using extensive.The influence of villaumite type deicing salt on environment mainly has：Corrode road and bridge, sewer pipe；Influence plant
Growth, causes green plants mortality；Polluted-water, influence organism normal growth, damage, destroy to human health
Ozone layer etc..Recently, organic deicing salt based on calcium magnesium acetate is developed, it is environmentally safe, but its snow melt effect is not
Such as sodium chloride, price is expensive, therefore limits its large-scale utilization and extention.
Therefore, invent that a kind of corrosivity is low, the good New Kind of Solvent of Snow-melted of snow melt effect to road deicing, strengthen road traffic peace
Complete and environmental protection various aspects all have positive meaning.
The content of the invention
Present invention mainly solves technical problem, be mostly villaumite type deicing salt for current most common deicing salt, this
Class deicing salt corrosivity is strong, influences plant growth, polluted-water, the defects of damaging to human health and environment, there is provided
A kind of preparation method of low-corrosiveness deicing salt.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of preparation method of low-corrosiveness deicing salt, it is characterised in that specifically preparation process is：
（1）The discarded duck oil dripped during Peking Duck Restaurant roast duck is collected, duck oil is poured into stainless steel pallet, then by pallet
Move into greenhouse, stand 10~15 days, it is become sour naturally mouldy, obtain the thing that becomes sour, it is spare；
（2）Lemon, konjaku and grape are weighed, is put into mortar, grinds 30~40min, mixed powder is obtained and minces, will be mixed
Crushed material and Yoghourt and concentration are 105The bacillus subtilis bacteria suspension of cfu/mL, which is fitted into fermentation tank, is used as fermentation substrate,
The water of the quality such as fermentation substrate is added into fermentation tank again, after stirring evenly, is sealed by fermentation；
（3）Treat it is above-mentioned after fermentation, open fermentation tank, take out tunning filtering, isolated ferment filtrate, then will fermentation
Filtrate is put into horizontal centrifuge, 15~20min of centrifugal treating, isolated centrifugation upper liquid；
（4）Weigh oyster shell to be put into high temperature furnace, calcine, obtain calcined material, after calcined material and water are mixed, stirring reaction 30~
It is separated by filtration to obtain filtrate after 40min；
（5）It will be fitted into after upper liquid and above-mentioned filtrate and spare thing mixing of becoming sour will be centrifuged in beaker, then beaker is moved into water
In bath, 60~70 DEG C are heated to, reactant is obtained after stirring 2~3h of reaction with glass bar, reactant is moved into and is rotated
In evaporimeter, concentrated by rotary evaporation obtains concentrate；
（6）Count, be fitted into after weighing 70~80 portions of above-mentioned concentrates and 15~20 parts of mixed with propylene glycol in colloid mill in parts by weight,
With rotating speed 30~40min of ground and mixed of 900~1000r/min, discharge after ground and mixed, tinning is melted up to low-corrosiveness
Avenge agent.
Step（1）Described in greenhouse temperature be 30~40 DEG C, relative air humidity be 60~70%.
Step（2）Described in lemon, the mass ratio of konjaku and grape be 5:3:1, mixed powder minces and Yoghourt and dense
Spend for 105The mass ratio of the bacillus subtilis bacteria suspension of cfu/mL is 10:2:1, the temperature of sealing and fermenting is 35~45 DEG C, close
The time of seal ferment is 10~12 days.
Step（3）Described in the rotating speed of centrifugal treating be 2000~3000r/min.
Step（4）Described in calcining heat be 900~1000 DEG C, calcination time is the quality of 2~3h, calcined material and water
Than for 1:3.
Step（5）Described in centrifugation upper liquid and the mass ratio of filtrate and the spare thing that becomes sour be 3:1:1, revolving is dense
The temperature of contracting is 80~90 DEG C, and the time of concentrated by rotary evaporation is 1~2h.
The beneficial effects of the invention are as follows：
The present invention collects discarded animal fat first, and is placed under hot and humid environment, through in biology, enzyme, air
Oxygen effect, occur spoiled by rancid oil or fat, obtain the thing that becomes sour rich in lipid and carboxylic acids, then will be enriched in organic carboxyl acid and starch
Fruit and konjaku blending fermentation, degrade, be rich under the action of Lactis In Yoghurt and bacillus subtilis
The zymotic fluid of fruit acid and lactic acid, is raw material the invention reside in oyster shell, after high-temperature calcination and water reaction, generation rich in calcium from
The clarification limewash of son, will finally become sour thing, zymotic fluid and limewash blending reaction, obtain reaction product, by reaction product and
Obtain low-corrosiveness deicing salt after mixed with propylene glycol, the wherein present invention will become sour thing, zymotic fluid and limewash blending reaction, become sour
Carboxyl and hydroxyl are rich on fruit acid and lactic acid molecules chain in thing and zymotic fluid, they and can clarify the calcium ion in limewash
The stronger complexing of generation, due to the presence of calcium ion, forms the copolymer similar to poly carboxylic acid derivative in reaction solution,
Its presence can strengthen the water absorbing capacity of deicing salt, can postpone congelation, so that strengthen the change ice ability of deicing salt, and
When the addition of propane diols can make it that deicing salt and ice crystal contact, thus it is possible to vary the vapour pressure of ice crystal surface, so as to significantly reduce
The freezing point of ice crystal, reaches snow melt purpose, when the oil substances and ice crystal contained in the thing that in addition becomes sour contact, can reduce ice
Hardness, improves the snow melt effect of deicing salt, since the main function component of deicing salt produced by the present invention is pure biology again
The organic monoacid salt of matter, thus it is low using the corrosivity of rear road pavement, can be voluntarily biodegradable, human body and environment will not be caused
Harm, has broad application prospects.
