Description

Hydrophily printing is with dusting and its production method
Technical field
The present invention relates to printing technology, more particularly to a kind of hydrophily printing is with dusting and its production method.
Background technology
In printing industry, non-dry ink and paper contact to prevent printed matter surface generate set-off, are being completed for printing After need to spray to dust in printed matter surface to be isolated paper and ink.
Currently, the oleophylic that commonly dusts is hydrophobic, it is easily adhered and causes cleaning difficult in print roller.In addition, existing spray Powder is there is also poor fluidity, the shortcomings of usage amount is big, airborne dust is big.
Invention content
The technical problem to be solved in the present invention is existing printing, poor fluidity poor with hydrophily of dusting, and usage amount is big, raises Dirt is big.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of printing of hydrophily with dusting, including The raw material of following mass fraction：
The grain size of the cornstarch is 10-40um, bulk density 0.50-0.60g/cm3。
Applicant has found that the bad major reason of existing performance of dusting is that jetted powder is uneven through studying for a long period of time. In use, the fine grained in product can spill into and cause airborne dust in air, environment is not only influenced, but also is difficult to clear up, simultaneously also The waste dusted is caused, the increase for the usage amount that causes to dust.Therefore, above-mentioned formula is proposed after the long-term research of applicant.? It is 10-40um by the size controlling of primary raw material cornstarch, the purpose is to the grains by controlling raw material in above-mentioned technical proposal Degree ensures the uniformity of product cut size, and the selection of the grain size, which can guarantee, to be also avoided that while powder fluidity and cause the airborne dust existing As.Cornstarch after silicone oil and flow promortor coating modification, lubrication, mobile performance it is excellent, can be evenly intersperse among printing Product surface avoids the occurrence of the effect for accumulation of dusting, while can also reduce usage amount, i.e., can be completed when dusting using a small amount of Overlay film, continuous printing protection is high, post-processing effect is good.In addition, the montmorillonite powder and non-surface-active agent that are added can improve The hydrophily of product.The oleophylic water-wet behavior of product can keep the gloss of printed article, while print roller is also easy to be cleaned.It is true On, the grain size of montmorillonite powder is preferably 100-150um, and coarseer powder can provide good support force, make air be easy into Enter the gap between cardboard and cardboard, accelerates the drying process of ink.
Further, the hydrophily is printed with dusting, and includes the raw material of following mass fraction：
The grain size of the cornstarch is 10-40um, bulk density 0.50-0.60g/cm3。
Further, the hydrophily is printed with dusting, and includes the raw material of following mass fraction：
The grain size of the cornstarch is 10-40um, bulk density 0.50-0.60g/cm3。
Further, the grain size of the montmorillonite powder is 100-300um.
Further, the humidity dusted is 5%-15%.
Further, the flow promortor is selected from nano silicon dioxide, nano-titanium dioxide, nanometer silicon carbide, stearic acid At least one of magnesium, gaseous oxidation aluminium, talcum powder.
Further, the nonionic surfactant is selected from alkyl phenol polyoxyethylene ether, stearic acid, polyvinyl alcohol, fat At least one of fat alcohol polyoxyethylene ether, alkylbenzene sulfonate, tween.
A kind of hydrophily printing production method dusted, includes the following steps：
(1) wet corn starch is spray-dried, crushes, after air current classifying and whirlwind grinding, and it is 10-40um to screen out grain size Cornstarch；
(2) cornstarch, silicone oil, montmorillonite powder, flow promortor, non-surface-active agent are subjected to the mixing that liquidates in proportion, It is uniformly mixed；
(3) drying and processing is carried out to mixture, the humidity for adjusting material is 5%-15%, is dusted.
In the above-mentioned technical solutions, wet corn starch is spray-dried, crushing, air current classifying, at whirlwind grinding and screening After reason, the high cornstarch raw material of grain size consistent degree, after surface-modified processing, Product dispenser, lubrication, stream can be obtained Dynamic property and isolation effect are good.The mixed process that liquidates is completed by a set of special installation, which carries out raw material at mixing head Liquidate mixing, and the basic principle of mixing head is to convert the pressure to speed, makes to generate the strong mixing work that liquidates between each component With mixing is evenly.The humidity of 5%-15% can guarantee that product has the cohesiveness of appropriateness, avoid generating dust raising phenomenon.
The beneficial effects of the present invention are：A kind of printing is provided with dusting and preparation method thereof, passes through to improve and is formulated and work Skill, obtains that mobile performance is excellent, printings of uniform particle sizes are with dusting, and Product dispenser, lubrication, mobility and isolation effect are good.
