Summary of the invention
The objective of the invention is for a kind of coating transfer film for decoration is provided, complicated with the brushing paint construction technology that solves prior art, decorative effect is single and the wallpaper cost of manufacture high, the problem of environmental protection and weatherability difference.
The object of the invention can be realized through following technical scheme.
A kind of preparation method of coating transfer film,, be followed successively by from outside to inside: five layers of formation such as bearing bed, release layer, printed layers, dope layer and adhesive layer; Its concrete preparation process is following:
Releasing layer coating is applied on the thick bearing bed base material of 0.012~0.1mm, after the oven dry rolling, utilizes intaglio press that the picture and text mirror image is printed in coated face; After waiting to dry rolling, utilize coating machine that dope layer is applied on the printed layers again, coating thickness reaches 98% above shading rate with paint film and is as the criterion, and can be coated with multipass according to the difference of coating method; After treating to dry fully, adhesive layer coating is coated on the dope layer oven dry back rolling; Through cutting into finished product again behind the embossing machine compacting decorative pattern.
The inventive method is applicable to the transfer membrane of multiple effects such as making is colour printed, monochromatic, embossing, cross cutting.Need not to carry out the printed layers technological operation if manufacture monochromatic transfer membrane.Need not carry out the embossing technique operation if make smooth effect.
The preparation method of described release layer, concrete steps are: by proportioning pigment is progressively added under 300 rev/mins stirring in the entry, then mixing speed is risen to 1000 rev/mins, stirred 20-30 minute, treat that pigment disperses the back subsequent use fully; The said emulsion of prescription is progressively mixed under 200-300 rev/min stirring by the prescription order; Under 1000 rev/mins state, stirred 10-20 minute, treat that emulsion mixes fully after, with 300 order screen cloths filtration one time; Placed 4 hours, and treated the coating that promptly is available on the machine behind the complete froth breaking.Generally require every square metre of coating of weight in wet base 30-100 gram.
Described dope layer preparation method; Concrete steps are: by proportioning polyvinyl alcohol (adhesive) and water are inserted in the agitated reactor; Under the stirring that per minute 80-100 changes; Be heated to about 95 ℃, kept 30-40 minute, treat that polyvinyl alcohol dissolves back subsequent use (emulsion adhesive need not carry out this technological operation) fully; Opacifier is added water puts in the container, with 1500 rev/mins mixing speed disperse 30-40 minute subsequent use; Filler is added water puts in the container, with 1000 rev/mins mixing speed disperse 10-15 minute subsequent use; Cetyl trimethyl ammonia bromide (surfactant) is added water put in the container, under 300 rev/mins of stirrings, be heated to 100 ℃, treat that it dissolves back subsequent use (the emulsion-type surfactant need not carry out this technological operation) fully; Pigment is progressively added under 300 rev/mins stirring in the entry, then mixing speed is risen to 1000 rev/mins, stirred 20-30 minute, treat that pigment disperses the back subsequent use fully; Above dissolving or scattered liquid are progressively mixed under 200-300 rev/min state; Under 1000 rev/mins state, stirring the 30-40 branch plants; After treating that solution mixes fully; Filter twice with 300 order screen cloths, place after 8 hours, treat the coating that promptly is available on the machine behind the complete froth breaking of solution.Generally require every square metre of coating of weight in wet base 200-500 gram.
The preparation method of described adhesive layer, concrete steps are following: aqueous binder added water put in the agitated reactor by prescription, under the stirring that per minute 80-100 changes, be heated to 80 ℃-90 ℃, kept 30-40 minute, treat that adhesive dissolves fully or gelatinization after subsequent use; Progressively mix under 200-300 rev/min stirring by prescription order and share; Under 1000 rev/mins state, stirring the 10-20 branch plants; After treating that solution mixes fully, filter one time, place and treated the coating that promptly is available on the machine behind the complete froth breaking in 4 hours with 300 order screen cloths.Generally require every square metre of coating of weight in wet base 50-80 gram.

Coating transfer film mainly is made up of for five layers bearing bed, release layer, printed layers, dope layer and tack coat etc.Be applicable to the transfer membrane of multiple effects such as making is colour printed, monochromatic, embossing, cross cutting.
At first releasing layer coating is applied on the thick PET of 0.012~0.1mm, BOPP, PP a kind of base material wherein; After the oven dry rolling; Utilize intaglio press that the picture and text mirror image is printed in coated face, after waiting to dry rolling, utilize coating machine that dope layer is applied on the printed layers again; Coating thickness reaches 98% above shading rate with paint film and is as the criterion, and can be coated with multipass according to the difference of coating method.After treating to dry fully, adhesive layer coating is coated on the dope layer, oven dry back rolling is if cut after needing the embossing effect also should pass through embossing machine compacting decorative pattern again.Need not to carry out the printed layers technological operation if manufacture monochromatic transfer membrane, need not carry out the embossing technique operation if make smooth effect.
During use, coating transfer film directly was soaked in the water 1~2 minute, directly is affixed on the metope that has coated putty after the taking-up, directly peel off surface protection film after 4 hours and get final product.
Coating transfer film is artistic diversity and the low cost of coating and a product of feature of environmental protection perfect adaptation with wallpaper.Its cost has only about 1/4th of wallpaper, can print and suppress floral designs, and the various vector pattern of computer lettering machine engraving system also capable of using make the office and the living environment of client's arbitrary decoration oneself in low-cost and environmental protection environment; In work progress, rejected the pollution of brushing technique, also greatly reduced the waste of coating simultaneously, made the thorough suitability for industrialized production of wall covering brushing technique, improved operating efficiency greatly, reduced construction cost construction environment; And because the use on a large scale of this transfer membrane, can make the corresponding reduction of synthesis technique index (will no longer receive the restriction of construction environment temperature, make its index range wideer) of coating common resins such as phenylpropyl alcohol, pure third gradegrade C stoste like film-forming temperature index in the stoste.
