Description

A kind of inkjet advertising light box cloth
Technical field
The present invention relates to a kind of for open air significantly advertising lamp box cloth, especially relate to a kind of inkjet advertising light box cloth.
Background technology
At advertisement field, " outdoor inkjet advertising light box cloth " is the maximum commodity of use amount, is widely used in outdoor significantly advertisement.By highway, railway, by street, the significantly advertisement on flooring is that outdoor spray painted cloth for lamp box is made invariably.Current " outdoor inkjet advertising light box cloth " is all PVC material, and namely adopt terylene line through netting, positive and negative is that the heat seal of PVC skin forms." PVC inkjet advertising light box cloth " is although technique is simple, with low cost, also there is many fatal weakness: (1) not environmentally, it can discharge HCl more than 60 DEG C, to environmental concerns.(2) printing effect is not good, and can not compatible solvent type, environmentally-frieweak weak solvent type and UV curing type three kinds of ink printed.(3) quality is heavy (common all at 400 ~ 600g/m 2between), resistance to low temperature difference (-20 DEG C), therefore harsh climate condition can not be resisted out of doors.(4) blotting rate of drying is printed undesirable.So " the outdoor inkjet advertising light box cloth " of being badly in need of a kind of environmental protection, printing effect good substitutes.
Summary of the invention
For the deficiencies in the prior art, the invention provides that a kind of printing effect is good, inkjet advertising light box cloth that blotting drying time is short.
The problem that will solve required for the present invention realizes by the following technical solutions: a kind of inkjet advertising light box cloth, comprise ink-absorbed coated layer, silane coupling agent, woven polyethylene cloth and polyethylene leaching membrane layer are formed, polyethylene leaching membrane layer adopts low-density high-pressure polyethylene, it is characterized in that: described ink-absorbed coated layer is by the polyvinyl acetate emulsion of 40 parts of solid contents 40%, the pure-acrylic emulsion of 40 parts of solid contents 40%, 6 parts of calcium carbonate, 1.5 parts of silicon dioxide powders, 1.5 parts of titanium dioxides, 0.2 part is pressed down bubble defoamer, 0.15 part of wetting agent, 0.26 part of brightening agent, 0.32 part of thickener and ammoniacal liquor is some is made into by weight.
Described silane coupling agent adopts the solvent borne polyurethane glue of two component.
The technique scheme that the present invention adopts, has following beneficial effect: (1) can compatible solvent type, environmentally-frieweak weak solvent type, UV curing type ink printed; (2) print resolution is high, reaches 1440dpi; (3) rate of drying is printed fast; (4) color density is high, and color rendition is good; (5) environmental protection, pollution-free, renewable.
Detailed description of the invention
Inkjet advertising light box cloth of the present invention comprises ink-absorbed coated layer, silane coupling agent, woven polyethylene cloth and polyethylene leaching membrane layer and forms, polyethylene leaching membrane layer adopts low-density high-pressure polyethylene, described ink-absorbed coated layer by the polyvinyl acetate emulsion of 40 parts of solid contents 40%, the pure-acrylic emulsion of 40 parts of solid contents 40%, 6 parts of calcium carbonate, 1.5 parts of silicon dioxide powders, 1.5 parts of titanium dioxides, 0.2 part is pressed down bubble defoamer, 0.15 part of wetting agent, 0.26 part of brightening agent, 0.32 part of thickener and ammoniacal liquor is some is made into by weight; Described silane coupling agent adopts the solvent borne polyurethane glue of two component.
Vinyon grain is first cutd open silk and is drawn into flat filament by the present invention, is made into plastic woven cloth; Again by plastic knitting reverse of the cloth film, silane coupling agent is coated in front, is finally coated with last layer ink-absorbed coated layer and becomes semi-finished product.
Starting stage of the present invention selects polyvinyl butyral resin as main coating material, but because polyvinyl butyral resin solubility property in alcohols solvent is better, in other kind solvent, solubility property is bad, the result of lab scale is that Weak solvent ink printed effect is fine, and strong solvent ink printed effect is bad, not even blotting.Determine again to walk emulsion coating route later.Can dissolve or swelling high molecular polymerization emulsion for multi-solvents according to collecting, successively ethyl acetate emulsion, pure-acrylic emulsion, acrylate and vinyl acetate emulsion are tried out, through the orthogonal experiment of tens times, finally show that employing ethyl acetate emulsion and pure-acrylic emulsion carry out composite, printing effect is best, and compatible three kinds of ink printed.
Emulsion after composite is high molecular polymer, and strength of coating is not high, not scratch-resistant, and we consider to add calcium carbonate superfine powder powder and ultra-fine aerosil powder for this reason, effectively enhance strength of coating; And adding due to powder, substantially increase and print blotting rate of drying.
The lab scale starting stage, the foam that in compound process, emulsion produces is a lot, is difficult to eliminate, the picture prickly heat shape causing coating surface to protrude by placing, close and numerous.We have selected emulsion general defoaming agent for this reason, i.e. mineral oils, and result is that defoaming effect is fine, but not affine with emulsion, causes coating surface levelability bad, rugged.Then select silicone-based defoamers again, defoaming effect and levelling are all fine, and the problem brought is that silicone causes the surface tension of coating to decline, and absorbency, the attachment fastness of inkjet printing all decline.Finally select polyether-type to press down bubble defoamer, be just able to basic solution.
Coating brightening agent through p-sulfonic acid type brightening agent, talan pyrrolotriazine derivatives with and the multiple brightening agent of pyrazoline type carries out selecting and whiteness test compares, finally determine to adopt talan pyrrolotriazine derivatives for best.
Through experiment, the optimum viscosity of coating between 500 ~ 600CPS, and composite after emulsion viscosity only have 300 ~ 350CPS.We successively have employed ammoniacal liquor and adjust pH value thickening, CMC thickening, all not good, have impact to the performance of emulsion.Finally select PU thickener, efficiently solve this problem.
Be coated in PE woven cloth by vinegar third mixed emulsion after composite, after drying, also loosely, peeling force only has 2 ~ 3N/2.5cm, can not be applicable to outdoor advertising demand in adhesion.Meeting blows rains heavily, and image coating may come off.We sound out in PE woven cloth, carry out the dizzy process of forceful electric power for this reason, still can not solve.Finally determine to adopt sided corona treatment, add painting silane coupling agent.Selecting at silane coupling agent, we have selected solvent acrylates glue, polyacrylate pressure-sensitive, water-borne polyurethane bond, solvent borne polyurethane glue respectively.Through tens contrast tests, finally determine to select the solvent borne polyurethane glue of two component ideal as silane coupling agent, the attachment fastness of coating reaches 12N/2.5cm.
The present invention is in print procedure, the ink dot of ink drops in the coating on lamp cloth surface, and the macromolecule resin due to coating can be alcohol in ink, ester, ketone equal solvent dissolve or swelling, thus lyosoption rapidly, prevent ink dot to the diffusion of X-Y direction, ensure that the out of roundness of ink-jet point.Dyestuff simultaneously in ink dot or pigment just rest on coating surface, complete printing.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, other multi-form change or variations can also be made on the basis of the above description.Here exhaustive without the need to also giving all embodiments, and these belong to apparent change that spirit of the present invention draws or variation is still among protection scope of the present invention.
