Description of drawings
Fig. 1 is hot transfer printing coated film and the bonding schematic diagram of glass.
The specific embodiment
Production with hot transfer printing color crystal glass is that example further specifies below.
One. the production of hot transfer printing coated film
1. selecting high-quality BOPET film for use is biaxially oriented polyester film 1 (referring to Fig. 1), and present case adopts Dupont 25um BOPET film, requires the single face sided corona treatment, more than surface tension 48 dyne.
With organic siliconresin with butanone, dilution with toluene (mass ratio of butanone and toluene is 1: 1), be coated on BOPET surface by trace and form even silicone resin coating 2, solidify by high temperature crystallization, design temperature curve in the dry run is fully got rid of solvent.During curing, satisfy 180 ℃ of crystalline temperature temperature, solidify fully about 6 seconds time.
Typical physical attribute with organic siliconresin after butanone, the dilution with toluene sees Table 1.
Table 1
3. be 8 seconds with the acrylic resin with butanone, dilution with toluene (mass ratio of butanone and toluene is 1: 1) viscosity to look into the grace cup No. 3,28 ℃ conditions, form evenly level and smooth conjunctiva layer 3 with the coating of 150 order reticulate patterns.
4. select vinyl chloride, vinyl acetate, the outer weather-proof pigment (German ECKAAT) of acrylate copolymer resins composite household for use, pigment content 8%-12%.To match colors according to different colours, call in auxiliary agent according to the requirement that is fit to intaglio printing in the resin, abundant dispersed with stirring, be ground to the fineness of 3-5um with three-roll grinder after dilution use.Be coated on formation ink lay 4 on the conjunctiva layer in the intaglio printing mode, it is fully dry that ink lay is wanted, and guarantees the solvent eliminating.During intaglio printing, relevant device should have electrostatic equipment to guarantee the transfer of meticulous site.Cause printing effect preferably for reaching, pay special attention to be coated with the interlayer tension variation during operation, can obtain reasonable print distinctness to successively decrease gradually.
5. add components such as micro-capsule curing agent, mixed solvent, levelling agent, dispersant, microgel and form hybrid resin in Polyester resin and Epoxy resin, the concrete prescription and the feature of hybrid resin see Table 2.Mixed solvent is made up of n-butyl acetate, propylene glycol monomethyl ether ethyl acetate, butanone, and their mass ratio is 4: 1: 5.
The feature of micro-capsule curing agent is: blow at micro-capsule more than 130 ℃, temperature curing agent below 130 ℃ can wrap up voluntarily, micro-capsule is blown the rapid and resin generation cross-linking reaction of back curing agent, about 150 ℃, form solid state preferably, this solidification process is irreversible gradual disposal solidifying, and it is outstanding to solidify back bond strength and adhesive force.
Fully stir after adding curing agent in the hybrid resin, whipping process does not adopt high-speed stirred, to avoid high speed processes heating or cutting micro-capsule, produces in advance and solidifies, and is separated into the master with middle stirring at low speed low speed.Be uniformly coated on formation hybrid resin adhesive layer 5 on the ink lay with anilox roll.Adopt secondary line coating process during coating, first pass is guaranteed coating weight, and second time coating is level and smooth bright and clean with applied assurance hybrid resin adhesive layer to be target, with the fineness of pattern after the assurance transfer printing.Drying after the coating is a standard to get rid of solvent, guarantees to get rid of totally, and baking temperature is no more than 120 ℃.The coating weight of hybrid resin is every square metre of 20g of wet film.
Table 2
6. bundling was stand-by after the production of hot transfer printing coated film was finished.
Two. glass transfer printing process and method
1. glass 6 is cleaned up by cleaning machine, washing liquid is pure water, through spray once more behind cascade spray, the sponge brush bar wiper, again by the rubber rollers water squeezing, dries after dispelling open fire with air knife during washing.
2. glass 6 is preheated to about 120 ℃, sends into pressing machine and realize pressing boiling hot transfer printing, press the process of scalding to realize hot transfer printing coated film and glass bidirectional location by the electric eye signal.Adopt high accuracy colour code probe and transmission device, positioning accuracy is about ± 0.3mm.Glass and hot transfer printing coated film are heated evenly in the boiling hot process of assurance pressure, and the silica gel roller surface temperature of pressing machine is not less than 180 ℃ of just transferabilities continuously, with speed, the pressure 4-8kg/cm of per minute 4M
2Transfer printing.
3. the BOPET film is thrown off and obtained blank.In fact silicone resin coating is bonded on the BOPET film after the transfer printing, the BOPET film is thrown off to be actually thrown off BOPET film and silicone resin coating.Blank is obtained hot transfer printing color crystal glass in the curing drying of carrying out 10 minutes under 180 ℃ of the temperature or carried out 30 minutes under 150 ℃ of temperature.After placing 48 hours at normal temperatures,, test hot transfer printing color crystal glass, all by experiment, meet every performance requirement according to the requirement of hundred lattice tests, salt spray test, high low temperature test, senile experiment and refrigerator panel frothing test.
Hot transfer printing color crystal glass is meant by hot transfer printing processing or in conjunction with hot pressing and scalds the safety glass that transfer technique is produced, tempered glass or ordinary plate glass, globoidal glass.
Hot transfer printing color crystal glass is that sided corona treatment is carried out on the BOPET film surface of 18um-25um with hot transfer printing coated film, layering coating organic siliconresin, acrylic resin, printing ink layer and coating Polyester and Epoxy hybrid resin layer.Press to scald transfer printing after heat transfer glass resin in the mode of thermosetting attached to glass surface, be that a kind of high temperature irreversibility is solidified, printing ink or paint that firmness after it solidifies and intensity are higher than normal temperature or low-temperature surface volatile dry far away have irreplaceable advantage.
At hot transfer printing coating film surface coating or printing micarex pearl essence or sudden strain of a muscle silver powder or glass microballoon, all can form color brilliant effect by the glass surface after transfer printing.But hot transfer printing coated film also combined vacuum coating and radium-shine embossing is produced various imitative metal effects and local laser effect, reveals the color crystal glass of various multi colour effects again.
Present embodiment is by to being that the film surface of base material carries out being coated with intaglio printing and coating after the sided corona treatment and has the hybrid resin of heat cure cross-linking reaction with the BOPET film, but produces the hot transfer printing coated film that transfer printing is scalded in voltage supply; Again by pressing ironing equipment, the lamination that is coated with on the hot transfer printing coated film is scalded and is transferred to glass back, by suitable cure parameter heating cure, form the hot transfer printing flat board or the cambered surface color crystal glass that have color pattern.It is strong in conjunction with firmness that this product has an ink lay, colour consistency is good, heatproof is weather-proof, the prolonged nondiscolouring of color effects, color is even, and picture and text printed with fine, resolution reach the characteristics of 600dpi, can also can produce various decorative effects in big plane or radian realization high-resolution on glass printed decoration greatly in conjunction with silk-screen and spraying.
Below by way of example the utility model is illustrated, but protection domain of the present utility model is not limited to above-mentioned instantiation the protection domain that all any improvement done based on the utility model or modification all belong to claim of the present utility model.
