Description
Technical field
The present invention relates to a kind of preparation methods of blotting material, belong to printing technique field.
Background technique
With the development of computer technology, digital imaging technology and network technology, inkjet printing technology has also been obtained rapidly
Development.With the continuous development in color inkjet printer market, main consumptive material color ink-jetting record material also increasingly causes
The attention of user.And the structure and preparation method of ink absorbing layer are then the core contents for researching and developing color ink-jetting record material, directly certainly
Determine the quality of print image, there is high researching value, resinae ink absorbing layer refers to that previous people often apply on printable fabric
The resins such as upper polyvinyl alcohol, gelatin, although its clarity is higher, blotting speed is slow.Pigment class ink absorbing layer then mainly contains spy
Fixed pigment particle, such as silica, aluminium oxide form the network for containing a large amount of micropores, to the ink droplet of spray printing in the coating
Serve and adsorbs simultaneously fixation.
Blotting material prints convenient, cheap etc. excellent since it has and image saturation good to color reducibility high
Point has obtained swift and violent, significant progress in recent years.The quality of blotting material final mass in blotting material largely by inhaling
The performance of layer of ink determines.But there is also certain problems during making and using for blotting material, if blotting material is to oil
The absorbability of ink is poor, and blotting material is oxidized easily, and is led to the disadvantage that service life is shorter, is limited its application.
Therefore, it is good to invent a kind of pair of ink absorption, have anti-oxidation function, novel blotting material with long service life,
There is positive meaning to printing technique field.
Summary of the invention
Present invention mainly solves the technical issues of, it is poor to the absorbability of ink to exist for traditional blotting material at present,
Blotting material is oxidized easily, and leads to the disadvantage that service life is shorter, provides a kind of preparation method of blotting material.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of preparation method of blotting material, it is characterised in that specific preparation step are as follows:
(1) weigh montmorillonite be put into pulverizer crush 30~40min after sieve with 100 mesh sieve, collect sieving montmorillonite powder, weigh
Rosemary is put into steam blasting tank, is passed through into cavity charge containers and is preheated to 200~220 DEG C of water vapour, until pressing in cavity charge containers
Power reaches 1.5~2.0MPa, and pressure maintaining handles pressure release explosion after 20~30min, obtains rosemary blast products, spare；
(2) it is fitted into ceramic pot after mixing above-mentioned montmorillonite powder and soybean oil as fermentation substrate, then adds into ceramic pot
Enter Pseudomonas aeruginosa bacteria suspension, is sealed by fermentation 7~10 days, obtains tunning；
(3) it is fitted into reaction kettle, is stirred to react after mixing above-mentioned tunning and spare rosemary blast products, stirring is anti-
It discharges after answering, obtaining reaction product is the prefabricated material of blotting；
(4) the prefabricated material of above-mentioned blotting is put into corona treatment equipment, sided corona treatment, modified blotting is obtained after sided corona treatment
Prefabricated material；
(5) according to parts by weight, 30~40 parts of polyvinyl alcohol, the prefabricated material of 30~35 parts of above-mentioned modified blottings, 3~5 part ten are weighed
Dialkyl benzene sulfonic acids sodium is put into batch mixer, is coated in PET base material after being stirred with coating machine, and control coating thickness is 2
~3mm is put into baking oven after coating, dries 1~2h at 80~90 DEG C up to blotting material.
The mass ratio of montmorillonite powder described in step (2) and soybean oil is 1:1, the additional amount of Pseudomonas aeruginosa bacteria suspension
It is the 10% of fermentation substrate quality, the concentration of Pseudomonas aeruginosa bacteria suspension is 106cfu/mL。
The mass ratio of tunning described in step (3) and spare rosemary blast products is 5:1, is stirred to react
Temperature is 40~50 DEG C, and the time being stirred to react is 10~12h.
The high-frequency ac voltage of sided corona treatment described in step (4) is 4000~5000V/m2, the speed of sided corona treatment
For 15~20m/min, the time of sided corona treatment is 30~40min.
The temperature being stirred described in step (5) is 90~95 DEG C, and the time being stirred is 30~40min.
The beneficial effects of the present invention are:
The present invention obtains rosemary blast products first using montmorillonite as raw material, then by rosemary steam blasting, will then cover
It ferments under the action of microorganism after de- soil powder and soybean oil mixing, obtains tunning, tunning and rosemary is quick-fried
The prefabricated material of blotting is made in object hybrid reaction of going bankrupt, and carries out sided corona treatment to the prefabricated material of blotting later and obtains the modified prefabricated material of blotting,
The prefabricated material of blotting and polyvinyl alcohol finally will be modified and other auxiliary materials are blended, it is of the invention up to blotting material after smearing is dry
During preparing blotting material, soybean oil is degraded using the microorganism in fermentation step, generates a large amount of ester groups and portion
Divide soybean lecithin, then ester group is introduced into montmorillonite surface under the action of microorganism, to increase the parent in montmorillonite matrix
Oiliness ester group radical amount, in conjunction with the high-specific surface area property of itself, is increased to ink so that montmorillonite lipophilicity enhances
Absorbability, and will form uniform micro- screen work structure between the montmorillonite added and rosemary blast products fiber has splendid absorption
Performance further increases the ink absorption ability of material, and in the imparted energy of the absorption of montmorillonite itself and rosemary blast products
Polyphenols inoxidizability, and enhance the inoxidizability of blotting material, be not easy to be oxidized, increase blotting material
Service life, the present invention also use sided corona treatment to be modified processing to blotting material, discharge high-frequency high-voltage using corona, produce
Raw tiny intensive electric spark impacts blotting material surface, makes blotting material surface parts molecular chain rupture and degrades, ink-absorbing material
Expect roughing in surface, increase its specific surface area, in addition the oxygen in high voltage electric field in air generates ionization and forms ozone, and aoxidizes modeling
Expect molecule, hydroxyl, carboxyl isopolarity group are generated on its strand, blotting material is made to be converted into polar surfaces, surface tension
Improving increases it to wetability, the adhesion of printing ink, has broad application prospects.
