Embodiment 1

[0141] According to the following steps, the roll-to-roll method is used to produce the wallpaper 1 with the LED light source attached to the flexible substrate of the present invention.

[0142] 1) Select a water vapor permeable polyethylene terephthalate (PET) film, and cut the PET film into a required width according to the wallpaper product design;

[0143] 2) putting the PET film roll on the feeder;

[0144] 3) printing a barrier layer (2) on the PET film (1) by screen printing and drying in a drying chamber at 120°C, where the barrier material is bisphenol A;

[0145] 4) printing a conductive circuit layer (3) with a conductive adhesive on the dried barrier layer (2) and drying at 280° C. to form a conductive circuit;

[0146] 5) Selecting a specific position on the conductive circuit according to the design requirements of the wallpaper to mount the LED light source with conductive adhesive to obtain a light-emitting layer (4);

[0147] 6) Curing the mounted LED light...

Embodiment 2

[0152] In the same manner as in Example 1, the roll-to-roll process was used to produce the wallpaper 2 with the LED light source attached to the flexible substrate of the present invention.

[0153] 1) Select a paper sheet that is permeable to water vapor, and cut the paper sheet to the required width according to the wallpaper product design;

[0154] 2) putting the paper roll on the feeder;

[0155] 3) printing the barrier layer (2) on the paper sheet (1) by screen printing and drying with UV, and the barrier material is bisphenol F;

[0156] 4) printing a conductive circuit layer (3) with a conductive adhesive on the dried barrier layer (2) and drying at 160° C. to form a conductive circuit;

[0157] 5) Select a specific position on the conductive circuit to mount the LED light source with solder paste according to the design requirements of the wallpaper to obtain the light-emitting layer (4);

[0158] 6) Heat and cure the mounted LED light source at 260°C;

[0159] 7)...

Abstract

The invention relates to a roll-to-roll method for producing wallpaper with an LED light-emitting source mounted on a flexible base material and the wallpaper produced by the method. The method includes: a step of unrolling the flexible base material, mounting one or more LED light emitting sources at preset positions on the surface of the flexible base material, and the one or more LED light emitting sources form a light emitting layer; a decorative layer The step of stacking is to stack the decorative layer on the surface of the flexible substrate with the luminous layer to obtain a laminated body, wherein the decorative layer has a hollow structure at a position corresponding to the LED light source at the preset position; The step of winding up the laminated body. The laminate includes wallpaper. The method of the invention can provide the wallpaper mounted with the LED light source, which has controllable, stable and sufficient luminous effect and can be mass-automatically produced. The method of the invention also has the advantages of light and thin material, easy integration of LED light sources, simple and easy operation, low cost and high efficiency.

Description

technical field [0001] The invention relates to a roll-to-roll method for producing wallpapers with LED light sources attached to flexible substrates and wallpapers produced therefrom. The method can realize mass automatic production of wallpapers with LED light sources. Background technique [0002] Traditional wallpaper is an important interior decoration material, and modern technology is combined with it to generate multi-functional wallpaper, which further broadens the application prospects of wallpaper. [0003] Luminous wallpapers are popular with consumers and are an important means of wall decoration, widely used in household, commercial and industrial fields. Patent Document 1 discloses a luminous decorative wallpaper, which is obtained by coating a luminescent paint SrAl on the wallpaper body 2 O 4 :Eu to obtain a luminous effect, but because the performance of chemical coatings is greatly affected by environmental factors and does not have time stability, the w...
