Description
Technical field
The present invention relates to a kind of preparation method of controllability Mildoxidation paraffin, belong to oxidized paraffin wax preparing technical field.
Background technology
The paraffinic base crude oil in the world is concentrated mainly on Asia, and China is paraffinic base crude oil resource and the most state of yield
Family.Although China's paraffin yield is very big, the transaction of domestic extraordinary wax product in the international market is scarcely out of swaddling-clothes, and
And paraffin kind composition is unreasonable, most of special wax, special wax product only have small lot production.
High added value paraffin wax product is developed, paraffin wax product can further be improved by improving the technology content of paraffin deep processed product
The market competitiveness.Paraffin can be widely applied to the industries such as chemicals, medicine, food, traffic.China is paraffin yield in the world
Maximum country, but high added value paraffin wax product is less, and the special special wax of most of purposes needs import.With science and technology
Development, the paraffin wax product of ordinary hard and fusing point can not meet the needs of market.As high temperature precision casting wax requires wax
With high rigidity, high intensity, small shrinkage factor, medical histopathologic slide then needs that hardness is high, low-melting paraffin wax, air-conditioning
Fusing point is then needed with heat-storing material no more than 55 DEG C new heat-storing material of low temperature etc., the wax of these specific uses all to hardness and
Toughness reguirements is higher.And paraffin matter is crisp at present, easy fracture, toughness is poor, and hardness is relatively low, is easily acted on and fragmentation by external force.
The content of the invention
The technical problems to be solved by the invention：Crisp for current paraffin matter, easy fracture, toughness is poor, and hardness is relatively low, easily
By external force effect the drawbacks of fragmentation, there is provided it is a kind of first by the microorganism in oil plant oil-containing mud, after culture is enriched with
Nutrient solution, then by paraffin and microwax mixed melting, under high-speed stirred state, dropwise addition is dispersed in nutrient solution, and mixing is sent out
Ferment activates, and adds the pliability of paraffin, makes it not easy to crack, then the powder wet feed after washing is mixed with calcium oxide and is able to
Dry and generate calcium hydroxide, for improving the hardness of product, then under the catalytic condition of manganese stearate, using compressed air to be weak
Oxidant, oxidized paraffin wax, solidify the method that controllability Mildoxidation paraffin is made through injection molding.Preparation process of the present invention is simple, institute
It is good to obtain toughness of products, hardness is high, solve thes problems, such as the easily fragmentation by external force effect.
In order to solve the above technical problems, the present invention is using technical scheme as described below：

40 DEG C, under 120~160r/min, cultivated 5~7 days in shaking table, then take nutrient solution obtained by 10~15mL pour into fill 80~
In the triangular flask of 100mL fresh cultures, under 35~40 DEG C, 120~160r/min, 5~7 days are cultivated in shaking table, such as
This totally 3 times repeatedly, centrifuge, discard lower sediment thing, take supernatant, obtain enrichment culture liquid；
（2）75~90g54# paraffin and 45~55g microwaxes are sequentially added into crucible, heating makes it melt completely, with
It is added dropwise to dropwise while hot afterwards in the fermentation tank for filling the above-mentioned gained enrichment culture liquid of 80~100mL, during dropwise addition, opens hair
Fermentation tank agitator, setting speed to 1200~1400r/min, wait to be added dropwise, stop stirring, be heated to 35~40 DEG C,
Heat-preservation fermentation 2~4 days, filter, remove filtrate, filter cake is washed with deionized 3~5 times, blended wax powder must be activated；
（3）Sequentially added in the three-necked flask with agitator 100~120g above-mentioned gained activation blended wax powder and
10~15g lime powders, then three-necked flask is placed in 160~180 DEG C of oil bath pans, stirred with 300~360r/min rotating speeds
10~15min of mixing is mixed, adds 0.04~0.06g manganese stearates, and lead into three-necked flask with 0.2~0.4m3/h speed
Enter compressed air, 2~4h of constant temperature stirring reaction；
（4）Question response terminates, and while hot pours into material in three-necked flask in mould, after it naturally cools to room temperature, takes off
Mould, produce controllability Mildoxidation paraffin.
The culture medium be by：2~4g ammonium nitrate, 1~2g dipotassium hydrogen phosphates, 2~4g potassium dihydrogen phosphates, 0.1~0.3g
Magnesium sulfate, 0.01~0.03g calcium chloride, 1~3g crude oil mix with 800~1000mL deionized waters.
The application process of the present invention：Controllability Mildoxidation paraffin produced by the present invention is added in ink, addition
For the 0.5~0.7% of ink quality, stirring makes it be sufficiently mixed uniformly, you can.Ink abrasion resistance and dispersiveness can be effectively improved,
Fast light and chemical property is good, and is acted on good anti-settling；The oxidized paraffin wax hardness is up to 6~10H, good toughness, is not easy
The fragmentation by external force effect, is worthy to be popularized and uses.
Compared with other method, advantageous effects are the present invention：
（1）Preparation process of the present invention is simple, and products obtained therefrom good toughness, hardness is up to 6~10H；
（2）Make full use of blended wax to be activated with nutrient solution mixed fermentation, improve the toughness of wax, then add calcium oxide and improve it
Hardness, solve the problems, such as the easily fragmentation by external force effect.
