Description
Technical field
The present invention relates to a kind of wall paper, aqueous polyurethane wall paper particularly relating to printable water color ink and preparation method thereof.
Background technology
Wallpaper, also referred to as wallpaper, wall paper, it is a kind of house decorative material for papering metope, because have the advantages that other house decorative materials multiple such as color is various, pattern enriches, easy construction, affordable are incomparable, be widely used in the interior decoration etc. in house, office, hotel, hotel.When family's interior decoration, due to the particularity that wallpaper has, the color of its finishing and style become the keynote of whole family, and the variation of wallpaper to meet in home decoration the principle of " with light packs repair, decorations of resetting " completely, therefore, is deeply subject to liking of consumers in general.Because people are to the requirement of house ornamentation also fashion individual character increasingly, wallpaper is more and more subject to many youthful high praises.
Current widely used wallpaper, its production technology generally adopts at base stock surface coating PVC paste resin, then drying (gel), cooling, make semi-finished product, then directly print with multicolour press, or first print embossing again, with wallpaper surface obtain color various enrich pattern.First, base stock generally with commercial wood pulp and inorganic filler processing, then is formed after melmac impregnation, and melamine Diazolidinyl Urea, the health of formaldehyde serious harm people.Secondly, the main component of coating is PVC, adjacent benzene class plasticizer, auxiliary agent, titanium dioxide and calcium carbonate etc., and wherein, adjacent benzene class plasticizer belongs to the Environmental Hormone affecting reproduction and growth, have a great impact developmental male reproductive system, the threat wherein suffered by child is higher than adult.In addition, generally adopt oil-based ink when embossing, and the main component of oil-based ink being TOL, MEK, DMF etc., there is VOC and remains in such technique, and VOC is residual also has tremendous influence to health.
As can be seen here, existing wallpaper is in production and manufacture process, owing to there being participating in of number of chemical harmful and noxious substance, cause wallpaper still can discharge various poisonous and harmful substance in use, especially formaldehyde, adjacent benzene class plasticizer and VOC, cause serious threat to environment and the healthy and safe of human body.
Summary of the invention
In order to overcome above-mentioned defect; the invention provides aqueous polyurethane wall paper of a kind of printable water color ink and preparation method thereof, not only can personalize pattern, and nonpoisonous and tasteless; very environmental protection, can be applicable to interior decoration simultaneously, attaches furniture and make house ads etc.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of aqueous polyurethane wall paper of printable water color ink, this aqueous polyurethane wall paper is three-decker, is followed successively by nonwoven layer, water-based PU layer and aqueous ink sorptive layer.
As a further improvement on the present invention, the thickness of described nonwoven layer is: 0.2-0.6mm, and described PU layer thickness is 0.2-0.4mm, and the thickness of described aqueous ink sorptive layer is 0.02-0.05mm.
As a further improvement on the present invention, described aqueous ink sorptive layer is the waterborne polyurethane resin of modification.
The present invention also provides a kind of aqueous polyurethane wall paper preparation method of printable water color ink, comprises the following steps:
1. prepare a release liners, apply water-based PU surface layer on the surface in this release liners side, drying obtains the water-based PU layer be compound on surface, release liners side afterwards;
2. on the surface of described water-based PU layer, water-based PU following layer is applied, and then on this water-based PU following layer compound nonwoven cloth, obtain the nonwoven layer being compound in water-based PU layer one side surface, after oven dry, this nonwoven layer is separated with described release liners with water-based PU layer;
3. can adsorb the waterborne polyurethane resin solution of the modification of water color ink at described water-based PU layer away from the opposite side surface coating of described nonwoven layer, dry and obtain aqueous ink sorptive layer.
As a further improvement on the present invention, described step 3. in, the coated weight of the waterborne polyurethane resin solution of described modification is 50-150g/m2.
The invention has the beneficial effects as follows: aqueous polyurethane wall paper of this printable water color ink and preparation method thereof adopts in release liners and applies water-based PU surface layer acquisition water-based PU layer, after water-based PU layer applying water-based PU following layer, compound nonwoven cloth obtains nonwoven layer, then release liners is separated, obtain semi-finished product, the last waterborne polyurethane resin applying modification on this half-finished PU layer forms aqueous ink sorptive layer, obtains finished product.Wherein, aqueous ink sorptive layer is printable layer, personalizedly can print or customize different patterns, meeting the demand that different crowd is different.This wall paper and preparation process thereof are all nonpoisonous and tasteless simultaneously, and it is good that traditional wallpaper performance not only compared by the wall paper obtained, long service life, and very environmental protection, can be used for attaching furniture, and interior decoration and house ads, be with a wide range of applications.
