Problems solved by technology

The disadvantage of this method is that ordinary inkjet paper contains a large amount of long fibers, and the shrinkage rate is large when it is bonded with a large amount of moisture-containing plant glue for wallpaper, and it is difficult to splice accurately during construction; It is prone to mildew and cannot meet the relevant national fire protection requirements

Embodiment 1

[0018] The production method of the digital inkjet wallpaper of the present invention comprises the following steps: 1. Dispersing silicon dioxide with an average particle diameter between 15-18 microns in the binder to form a water-based ink-absorbing coating, the water-based ink absorbs The paint has the function of absorbing ink; 2. Put the special base material for wallpaper, the special base material for wallpaper described in this embodiment is a special non-woven fabric for wallpaper, and place it on the unwinding mechanism; 3. Pass the feeding roller—chrome-plated roller or rubber The rotation of the roller coats the water-based ink-absorbing paint with ink-absorbing function on the surface of the special substrate for wallpaper to form an ink-absorbing layer, and at the same time uses a general-purpose coating air knife to achieve accurate coating measurement of the thickness of the ink-absorbing layer; The special substrate for wallpaper covered with an ink-absorbing ...

Embodiment 2

[0020] The steps of this embodiment are basically the same as those of Example 1, except that the particle size of the silicon dioxide used is between 13-16 microns; The silicon oxide content was 3.3 grams.

Embodiment 3

[0022] The steps of this embodiment are basically the same as those of Example 1, except that the particle size of the silicon dioxide used is between 8-12 microns; The silicon oxide content was 3 grams.

[0023] According to the comparison of Examples 1-3, the smaller the particle size of the silica, the more vivid the color of the pattern printed on the digital wallpaper, the faster the ink dries, and the better the waterproof performance.

[0024] Therefore, the digital ink-jet wallpaper of the present invention has a two-layer structure from top to bottom: the special base material for wallpaper and the ink-absorbing layer formed by the surface coating water-based ink absorption coating of the special base material for wallpaper; The coating includes a binder and silica dispersed in the binder with an average particle size of less than 20 microns. The adhesive used in the present invention is commercially available North Organic VAE latex, and of course, other adhesives w...

Abstract

The invention discloses digital ink-jet wallpaper and its production method. The production method of the digital ink-jet wallpaper comprises the following steps of: firstly dispersing silica, the average particle size of which is less than 20 micrometers, into an adhesive to form an aqueous ink absorbing paint; then coating the aqueous ink absorbing paint on the surface of a wallpaper special-purpose base material to form a blotting layer; and finally successively drying and cooling the wallpaper special-purpose base material coated with the blotting layer to obtain the digital ink-jet wallpaper finished product. As the surface of the wallpaper special-purpose base material is coated with the aqueous ink absorbing paint containing silica with its average particle size being less than 20 micrometers, the color of patterns printed on the digital wallpaper by a common printer is vivid and distinct, ink dries rapidly, and simultaneously the wallpaper has a certain waterproofness, meets technological requirements of wallpaper construction as well as national requirements on fireproof and environmental protection aspects of interior decorative materials.

Description

technical field [0001] The invention relates to a digital inkjet wallpaper and a production method of the digital inkjet wallpaper, which can be used as an ordinary water-based inkjet digital printer to print wallpaper. Background technique [0002] At present, the surface printing of wallpaper on the market generally adopts the following three processes: [0003] 1. Use printing to print patterns on non-woven fabrics and other substrates, which is the process used by most wallpaper manufacturers. This method is not suitable for multi-variety and small-batch production methods. If the customer requests to customize a special pattern, the production cost of the printing process will be very high. [0004] 2. Use solvent or eco-solvent ink inkjet printers to print patterns directly on wallpaper substrates. The disadvantage of this method is that solvent or weak solvent ink is not environmentally friendly, has a strong smell, and is not suitable for interior decoration. [...
