Description
Technical field
The invention belongs to printing technologies, and in particular to a method of improve stone paper packaging material printing quality.
Background technique
Stone paper, is also Shi Kezhi, and stone paper new technology is based on mineral resources calcium carbonate the most abundant in the earth's crust
Raw material is wanted, using high molecular material and a variety of inorganic matters as auxiliary material, utilizes the macromolecule interfacial principles of chemistry and filling-modified skill
Art is recycled through a kind of invertibity that special process is process, and has the characteristics that the novel papermaking technology of modern technologies.By
After trapezoidal milling machining, the calcium carbonate in lime stone is extracted, ore is then worn into high calcium by SCM superfine mill
The superfine powder of 1500-2500 mesh then carries out second operation work, and mother is made in the additive that 85% modified calcium carbonate adds upper 15%
Paper or bag is made finally by film blowing device is squeezed in grain.
For stone paper compared with traditional wood pulp paper, stone paper has its unique advantage, and this kind of paper production not cut down tree
Wood, the not discharge of waste water and gas is more more smooth than traditional paper, it had not only promoted the transition of traditional paper-making industry but also had promoted
The upgrading of chemical industry, in the following under cover huge business opportunity.In terms of printing production: stone paper is because of its stiffness, absorbency
More there is superiority than conventional paper, the printing effect that it is presented prints more aobvious solid layer feeling than traditional paper, and stone paper is wide at present
It is general to be useful in gift box, cosmetic container, packing case, handbag production, printed design, poster publicity, publicity specification, map, do not do
Glue, drop production, the industry being related to also embrace a wide spectrum of ideas.But at present but there is printing figure in the printed matter made of stone paper
The problems such as text is apprehensive, color saturation is bad, and affect the further expansion application of stone paper.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of side for improving stone paper packaging material printing quality is provided
Method.
The present invention is achieved by the following technical solutions:
A method of stone paper packaging material printing quality is improved, is included the following steps:
(1) removal of impurities is handled:
Air-blowing processing is carried out with surface of the compressed air to stone paper, with remaining granule foreign standby in air removal stone paper
With；
(2) atomized spray is handled:
After step (1) treated stone paper tiling is put well, recycle atomized spray equipment by the water-soluble liquid mist of silane coupling agent
Change is sprayed on the surface of stone paper；
(3) it is dried:
By step (2), treated that stone paper is put into vacuum oven is dried, and the water content of stone paper is done
It is dry spare to taking out after 5 ~ 7%；
(4) corona treatment:
By step (3), treated, and stone paper is put into plasma processing apparatus, and the voltage for controlling electric discharge is 4 ~ 4.5kV,
Electric current is 35 ~ 40mA, and frequency is 18 ~ 20kHz, is taken out stone paper after 2 ~ 3min of processing spare；
(5) storage is handled:
By step (4), treated that stone paper is put into takes out and can carry out at printing after 5 ~ 7h of storage processing in nitrogen environment
Reason.
Further, control pressure is 0.4 ~ 0.45MPa when air-blowing as described in step (1) is handled.
Further, in silane coupling agent aqueous solution described in step (2) silane coupling agent volume fraction be 20 ~
25%；The silane coupling agent is silane coupling agent kh550, silane coupling agent kh560, any in silane coupling agent kh570
It is a kind of；The atomized spray amount of the silane coupling agent aqueous solution is the 22 ~ 26% of stone paper gross mass.
Further, it is 1 ~ 10Pa, temperature that the air pressure in vacuum oven is controlled when drying process described in step (3)
It is 70 ~ 75 DEG C.
Further, it is air that atmosphere is controlled when corona treatment described in step (4).
Further, its electrode discharge form is that dielectric impedance corona is put when corona treatment described in step (4)
Electricity, block media select aluminium oxide ceramics.
Further, the temperature control of nitrogen environment described in step (5) is 22 ~ 25 DEG C, relative humidity is 60 ~ 65%.
The present invention has carried out special working process to stone paper, effectively improves its printing using quality, improves
Its application value eliminates most defect problems of existing stone paper.Wherein, removal of impurities processing first is carried out to stone paper, blown away
The little particles impurity such as raw material on stone paper surface is convenient for subsequent processing, atomized spray processing has then been carried out, by silane
Coupling agent aqueous solution atomized spray, so that silane coupling agent has been immersed in stone paper, changes carbon on the surface of stone paper
The surface-active of the matrixes such as sour calcium, resin, especially optimizes the surface property of resin matrix, when common printed processing, because of tree
Affinity is not strong between aliphatic radical body and ink, and the part colours for being easy to cause surface resin matrix to be printed are not deep, persistence is not high,
And its affinity is able to promote improvement after treatment；And it equally will affect in calcium carbonate there is also certain impurity component
The effect of printing, this measure equally enhance its printable processing performance；It is then dried, with vacuum drying treatment
Mode can remove excessive moisture, and can guarantee the physical and chemical performance for not damaging paper, then carry out corona treatment, although
Silane coupling agent can improve the surface-active of calcium carbonate, but part silane coupling agent can be in calcium carbonate after atomized spray processing
Surface filming, transition have wrapped the surface of calcium carbonate, cause subsequent printing ink to penetrate into and combine the problems such as ineffective, this progress
Corona treatment the overlay film of silane coupling agent can be abolished, improve the specific surface area of calcium carbonate, while can also be to carbon
The type and content that sour calcium carries out surface active groups are enhanced, so that calcium carbonate is adsorbing fixed ink with General Physics
While, also there is the performance for being chemically crosslinked fixed ink well, further ensure whole printing effect；Finally carry out
Storage processing, is conducive to the stabilization of stone paper surface property.
The present invention has the advantage that compared with prior art
The present invention has carried out special processing to stone paper packing material, it will be apparent that improves it and prints processing performance, printing
Precision it is good, condition is high, quality is stable, the great market competitiveness and application value.
