Abstract

The invention discloses novel HS white gravure ink. The novel HS white gravure ink relates to the field of printing ink. The novel HS white gravure ink comprises: 18 to 23% of synthetic wax, 7 to 12% of a black pigment, 1 to 2% of an additive, 1 to 2% of alcohol, 3 to 8% of vinyl acetate, 25 to 30% of methyl vinyl ketone and 33 to 38% of toluene. The novel HS white gravure ink can be prepared into sticky ink after being attached with a heat-sealing material, saves processes, reduces the number of product layers, has a downy tactility and broadens a use range.

Description

A kind of novel HS white base gravure ink

Technical field:

The present invention relates to the printing-ink field, relate in particular to a kind of novel HS white base gravure ink.

Background technology:

A few days ago, substantially all be to need parting agent, printing ink, glue at the base gravure ink of selling on the market; Base gravure ink is how the characteristic of cylinder is invigorated, both utilized 5-7 μ, thick in the about coating of 40 μ left and right sides printing ink just can become good print, just can become the good printing ink of viscosity so will keep solidity for (approximately 50%～55%) and tackiness (No. 4 cup approximately 15～40 seconds).Recently the high speed along with gravure printing machine is inclined to, such demand is also increasing, during take print speed 200m/minxq as benchmark, transfer of ink is not approximately 20%～25%, 100m/minxq is about 20%～30%, being about 30%～35% not transfer of ink during 50m/min can stay in the unit, according to centrifugal force raising maximum transfer degree is exactly that solidity is high, the printing ink that viscosity is low just may, printing ink is the substantivity effect that plated film shows color and luster and relates to that is printed on when printing, when being printing, keeps by glue the effect of the viscosity between the plated film that is transferred and is printed on printing ink plated film top, currently available products need to apply glue on printing ink in addition, so relate to the projects such as expense and engineering, coat in addition the more and more boldness that has influence on product of layer on the transfer printing body, and touch up very coarse.

Summary of the invention:

The purpose of this invention is to provide a kind of novel HS white base gravure ink, it can be enclosed heat-sealing at general printing ink and make sticking printing ink, has saved engineering, has reduced the number of plies of product, and sense of touch is softer, has increased use range.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its prescription consists of: synthetic wax 18-23%, black pigment 7-12%, additive 1-2%, alcohol 1-2%, vinyl acetate 3-8%, ethylene methacrylic ketone 25-30%, toluene 33-38%.

Its preparation technology is: take the cooperation of finished product as benchmark, calculate required starting material quantity and tell the site work responsible official, on-the-spot responsible official is to making the required solvent (alcohol of finished product, toluene), resin (vinyl acetate, ethylene methacrylic ketone), pigment, additive, the amount of the materials such as tinting material is confirmed, solvent (alcohol, toluene) volatility is more intense, so 1.01～1.03 times of guaranteeing aequum at ordinary times, (joining rate different according to the characteristic of needed amount and product) guarantees solvent (alcohol in advance, toluene) the reason supplementing solvent (alcohol in postpartum that prevents from making a living, toluene) the loaded down with trivial details property that again stirs the time, remaining amount keeping is in jar, use together when having the suffering of equally joining rate to receive, receive solvent (alcohol, toluene) build lid after, the volatilization amount control to minimize the keeping, resin (vinyl acetate, ethylene methacrylic ketone), tinting material, additive is with solvent (alcohol, toluene) mix with stirrer by required amount, at this moment be noted that and put first solvent (alcohol, toluene) put pigment after with solvent (alcohol, toluene) well mix, the resin (vinyl acetate of finishing, ethylene methacrylic ketone), tinting material, the materials such as additive are put in the solvent that takes good care of, putting white pigment into stirs again, make it to reduce the amount that floats up, the finished product of working good is put in the shredder, the molecular dispersion of pigment, the size that can not with the naked eye find out when pigment molecule should keep being transferred to transfer printing body, behind the gravimetry, not enough amount solvent (alcohol, toluene) fill, with wrapping machine finished product packing is got up, stick again labeling and express the date manufactured.

The present invention can enclose heat-sealing at general printing ink and make sticking printing ink, has saved engineering, has reduced the number of plies of product, and sense of touch is softer, has increased use range.

Embodiment:

This embodiment is by the following technical solutions: its prescription consists of: synthetic wax 18-23%, black pigment 7-12%, additive 1-2%, alcohol 1-2%, vinyl acetate 3-8%, ethylene methacrylic ketone 25-30%, toluene 33-38%.

This embodiment can be enclosed heat-sealing at general printing ink and be made sticking printing ink, has saved engineering, has reduced the number of plies of product, and sense of touch is softer, has increased use range.

Claims

1. a novel HS white base gravure ink is characterized in that its prescription consists of: synthetic wax 18-23%, black pigment 7-12%, additive 1-2%, alcohol 1-2%, vinyl acetate 3-8%, ethylene methacrylic ketone 25-30%, toluene 33-38%.

2. a kind of novel HS white base gravure ink according to claim 1, the preparation technology who it is characterized in that it is: take the cooperation of finished product as benchmark, calculate required starting material quantity and tell the site work responsible official, on-the-spot responsible official is to making the required solvent of finished product, resin, pigment, additive 1-2%, the amount of the materials such as tinting material is confirmed, the volatility of solvent is more intense, so 1.01～1.03 times of guaranteeing aequum at ordinary times, the loaded down with trivial details property that the reason of guaranteeing in advance solvent prevents from making a living and again stirs during supplementing solvent postpartum, remaining amount keeping is in jar, use together when having the suffering of equally joining rate to receive, build lid after receiving solvent, the volatilization amount control to minimize the keeping, resin, tinting material, additive 1-2% mixes with stirrer by required amount with solvent, at this moment be noted that to put first and put pigment behind the solvent and well mix with solvent, the resin of finishing, tinting material, the materials such as additive are put in the solvent that takes good care of, putting white pigment into stirs again, make it to reduce the amount that floats up, the finished product of working good is put in the shredder, the molecular dispersion of pigment, the size that can not with the naked eye find out when pigment molecule should keep being transferred to transfer printing body, behind the gravimetry, not enough amount is filled with solvent, with wrapping machine finished product packing is got up, stick again labeling and express the date manufactured.
