Abstract

The invention relates to a cold-ironing film coloring coating material. The cold-ironing film coloring coating material solves the problems of poor trimming property, poor transfer effect, incapacity of surface mould pressing and the like in the prior art. The cold-ironing film coloring coating material comprises the following components in parts by weight: 10-30 parts of ogranic silicon modified acrylate resin, 0-10 parts acrylic modified alkyd resin, 0-15 parts of polyurethane resin, 5-15 parts of cellulose resin, 5-15 parts of chlorinated polypropylene resin, 1-5 parts of a wetting agent, 0-30 parts of dyes and 60-100 parts of an organic solvent. According to the cold-ironing film coloring coating material, a release layer is not required to coat a BOPET(biax orientation polyester film) in advance in a using process, so that the cold-stamping film coloring coating material has excellent trimming performance; meanwhile, the coating can be subjected to mould pressing, and the coating subjected to mould pressing has the advantages such as a long-term and stable laser effect and the like.

Description

A kind of cold stamping film colored film material

Technical field

What the present invention relates to is a kind of speciality polymer material, particularly a kind of possess excellent trimming, moldable, without the need to the prior cold stamping film colored film material being coated with release layer in BOPET film.

Background technology

Cold wave printing is an important breakthrough in printing technology in recent years, it combines traditional printing and coating technique, and it is simple to operate, printing house uses existing printing equipment, just can to apply in a flexible way cold wave technology, create with crowd under with effect, under only reduce production cost, also again create the value added of product, thus become following new trend.

Cold wave technology principle: utilize flexographic plate to be printed on paper tape in UV glue local or full version, and with transfer film compound, then through UV light irradiation, glue instantaneous solidification, again through peeling off, the radium-shine layer on transfer film according to the design transfer on forme on paper tape, will form magnificent packaging effect.Why be called that cold wave (cold transfer) is that be different from traditional hot stamping, this technology is applied in phonecard and drug packaging the earliest because it does not need heating.

Existing cold stamping film colored film material, unreasonable owing to filling a prescription, difficulty is controlled large when causing use, easily occur that trimming is bad, transfer effect is poor, cannot the problem such as surperficial mold pressing, need to be coated with special separated type material before painted simultaneously, have impact on production efficiency to a certain extent, cost is higher.

Summary of the invention

In order to overcome the defect of prior art, the invention provides one in use without the need to being coated with separated type material in advance in BOPET film, possessing excellent trimming, coating is moldable, after mold pressing, laser effect is stable for a long time, and production efficiency is high, the cold stamping film colored film material that use cost is low.

To achieve these goals, the technical solution used in the present invention is as follows: a kind of cold stamping film colored film material, and its composition and weight proportion are: organosilicon modified crylic acid resin 10 ~ 30 parts, acrylic acid modified alkyd resin 0 ~ 10 part, urethane resin 0 ~ 15 part, celluosic resin 5 ~ 15 parts, chlorinated polypropylene 5 ~ 15 parts, wetting agent 1 ~ 5 part, dyestuff 0 ~ 30 part, organic solvent 60 ~ 100 parts.

Described wetting agent is polyxyethylated alkylphenol.

Described organic solvent is butanone or vinyl acetic monomer or N-BUTYL ACETATE or pentanone or propyl carbinol or the composition between them.

Prepare the method for above-mentioned cold wave colored film material, its method steps is:

1), by described recipe requirements, whole organic solvent is dropped in reactor, under stirring at low speed, is heated to 25 DEG C ~ 35 DEG C;

2), under stirring at low speed state, with form in batches, repeatedly add the dyestuff of recipe requirements ratio on a small quantity, be adjusted to low speed after 30 minutes again until moderate-speed mixer after dyestuff feeds intake and continue to stir;

3), under stirring at low speed state, described organosilicon modified crylic acid resin, acrylic acid modified alkyd resin, urethane resin, celluosic resin, chlorinated polypropylene, wetting agent are dropped in reactor successively in proportion, first stirring at low speed 1 ~ 1.5 hour, then moderate-speed mixer 0.5 ~ 1 hour;

4), stop stirring, reactor temperature is controlled at 42 ~ 45 DEG C, keep 3 hours;

5), 20 DEG C are slowly cooled to, for subsequent use with pouring into after strainer filtering.

The present invention compared with prior art, has without the need to being coated with release layer in advance in BOPET film, excellent trimming, the features such as coating is moldable, and after mold pressing, laser effect is stable for a long time, and production efficiency is high, and use cost is low.
