The specific embodiment
For making purpose of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The invention provides a kind of water transfer printing production technology that is applied to sanitaryware, can be as required at the various patterns of sanitaryware surface printing, clear patterns, make people can enjoy to the full when the product that uses the present invention to make visual attractive in appearance, improve people's quality of life.Sanitaryware of the present invention can be tap, towel rack etc.The water transfer printing production technology of described sanitaryware specifically comprises the steps:
A. pretreatment procedure
Comprise polishing and cleaning, at first with sander or manually with sand paper, that the sanitaryware surface finish is level and smooth, then with clear water or surface cleaner, that its surface clean is clean.
B. plastic-blasting operation
For make sanitaryware have hardness high, do not come off for a long time, do not fade, characteristic that wearability is good, dusted in sanitaryware surface after pre-treatment, the coating that adopts is epoxide powder coating or acrylate powder coating, form bottom, this coating (epoxide powder coating or acrylate powder coating) is comprised of thermosetting resin, curing agent, pigment, filler and auxiliary agent etc., have excellent and metlbond power, anticorrosive property, hardness, pliability and impact strength, coating is combined better with the base material (metal or plastics) of sanitaryware; Too thin or too thick and affect its adhesion property for fear of underlayer thickness, it is 50 ~ 70 microns that underlayer thickness requires, and after dusting, sanitaryware is toasted levelling, baking temperature is 180 ℃ ~ 220 ℃, be preferably 190 ℃ ~ 210 ℃, stoving time is 40 ~ 60 minutes, is baked to fully to solidify.When baking temperature can not make bottom solidify fully lower than 180 ℃, and temperature will make bottom more solvent pop or pin hole occur during higher than 220 ℃, and in addition, stoving time is also unsuitable long, easily make bottom dry and cracked and affect its adhesion property.The present invention has improved the hardness of product by specific coating, baking temperature and stoving time in the plastic-blasting operation, has increased the adhesive force of product surface to paint, prevents that paint from fading.
After sanitaryware is carried out the plastic-blasting operation, can also polish to the bottom that product surface forms, make its surface more smooth, there is no a uneven phenomenon.
C. painting process
Painting process comprises spray paint and baking.At first spray paint on bottom, in order to make the water transfer printing that better effect be arranged, described paint adopts industrial paints or automotive paints, first-selection is automotive paints, because automotive paints mainly are comprised of resin, pigment, auxiliary agent, filler, curing agent, solvent etc., have good mechanical performance, richness is good, gloss is high, also have adhesive force and hardness height all relatively good, paint is combined better with bottom, makes it be difficult for dropping.Too thin or too thick and affect it with the tack of bottom, water transfer printing film picture and text layer for fear of paint thickness, it is 30 ~ 40 microns that paint thickness requires, and painting color can be chosen as required, can select white, black, green etc.After spraying paint, sanitaryware is toasted, the purpose of baking is paint to be dried to fully solidify, and baking is for the bathroom metalwork, and its baking temperature is 130 ℃ ~ 150 ℃, is preferably 135 ℃ ~ 145 ℃, and stoving time is 30 ~ 40 minutes; Consider that working of plastics can not bear too high temperature, the baking temperature of bathroom working of plastics is 50 ℃ ~ 75 ℃, is preferably 60 ℃ ~ 70 ℃, and stoving time is 60 ~ 90 minutes.Like this, both can avoid sanitaryware to cause after the water transfer printing picture and text layer to adhere to because baking temperature is too high bad, also can reach best drying effect simultaneously.If it should be noted that sanitaryware includes metal and plastics bi-material simultaneously, its baking temperature is consistent with above-mentioned bathroom working of plastics, and stoving time can be considered suitable lengthening.The present invention makes skin of paint more smooth, smooth by paint, baking temperature and stoving time in painting process, and without film site, levelling is effective, has improved product surface glossiness, adhesive force and hardness.
D. water transfer printing process
After step c, water transfer printing film is lain against on the tank water surface, and make the picture and text layer up, then at normal temperatures activator is sprayed on water transfer printing film the picture and text layer is activated, after 30 ~ 50 seconds, sanitaryware is pressed close to water transfer printing film and pressed downward in water 8 ~ 15 seconds, the picture and text layer on water transfer printing film is transferred to product surface under the effect of hydraulic pressure.The time of repose of 30 ~ 50 seconds makes activator can fully activate the picture and text layer at normal temperatures, makes picture and text layer good stability, is less than 30s and will causes the picture and text layer fully not separate from water transfer printing film, and will cause the picture and text layer smudgy greater than 50s.In order to guarantee that the picture and text layer is printed in the effect on paint, make clear patterns fine and smooth, sanitaryware should continue 8 ~ 15 seconds under the effect of hydraulic pressure.In the water transfer process, should make the water surface keep static before product applying water transfer printing film, avoid picture and text layer distortion in the applying process, the applying speed that should note sanitaryware and water transfer printing film during applying will keep even, avoid the water transfer printing film fold, avoid hard form matter to touch water transfer printing film and cause water transfer printing film to break.The present invention makes the clear exquisiteness of pattern, smooth surface, beautiful in colour by the water transfer printing process.
After the water transfer printing, can also clean product with clear water, wash away water transfer printing film and fail to be attached to floating layer on product surface.
E. drying process
Sanitaryware after the water transfer printing is put drying or heating, drying at normal temperatures, remove the moisture of product surface, during heating, drying, be out of shape because bake out temperature is too high for fear of sanitaryware, be able to finish-drying for the picture and text layer that makes the water transfer printing simultaneously, the bake out temperature of bathroom metalwork is 100 ℃ ~ 120 ℃, be preferably 105 ℃ ~ 115 ℃, drying time is 20 ~ 30 minutes, and the bake out temperature of bathroom working of plastics is 40 ℃ ~ 60 ℃, be preferably 45 ℃ ~ 55 ℃, drying time is 30 ~ 45 minutes.If it should be noted that sanitaryware includes metal and plastics bi-material simultaneously, its bake out temperature is consistent with above-mentioned bathroom working of plastics, and drying time can be considered suitable lengthening.
F. spray the gloss oil operation
in order to make the pattern that is printed in the sanitaryware surface be subject to better protection, after drying process, at sanitaryware surface uniform ground application one deck gloss oil, mummification, described gloss oil first-selection is the automobile gloss oil, it is good that the automobile gloss oil has a richness, gloss is high, strong adhesion, hardness is high, the advantages such as the scratch resistance ability is strong, in spraying process, the thickness requirement of gloss oil is 40 ~ 50 microns, mummification adopts nature dry or dry, long because of drying time for fear of sanitaryware, excess Temperature and cause the product surface flavescence, also can reach simultaneously best drying effect, during oven dry, the bake out temperature of bathroom metalwork is 100 ℃ ~ 120 ℃, be preferably 105 ℃ ~ 115 ℃, drying time is 20 ~ 30 minutes, the bake out temperature of bathroom working of plastics is 40 ℃ ~ 60 ℃, be preferably 45 ℃ ~ 55 ℃, drying time is 30 ~ 45 minutes.The present invention makes wear-resisting, the anti-xanthochromia of product by specific gloss oil, baking temperature and stoving time in the blast finishing ink operation, and the scratch resistance ability is strong.
