LED (light-emitting diode) curing edge sealing strip

Abstract

The utility model relates to an LED (light-emitting diode) curing edge band, which comprises a base material layer, a water-based ink layer and an LED curing coating layer, the water-based ink layer is covered on the surface of the base material layer, and the LED curing coating layer is covered on the surfaces of the water-based ink layer and the base material layer.

Meanwhile, as the luminous intensity of the LED curing lamp is higher than that of a UV mercury lamp tube, the curing effect of the LED curing coating layer is better, and the production quality is improved; the LED curing lamp does not need to be preheated in the using process, so that the preheating time can be saved, the curing interval time is effectively shortened, and the production efficiency of the LED curing edge sealing strip is effectively improved.

Description

Technical Field

[0001] The utility model relates to the technical field of edge banding strips, in particular to an LED curing edge banding strip. Background Art

[0002] Edge banding is a material used to protect, decorate and beautify the cross section of furniture boards. It can make a piece of furniture appear with clear wood grain and colorful overall effect. Edge banding generally includes a substrate layer, an ink layer and a protective layer. The ink layer is printed on the surface of the substrate layer, and the protective layer covers the ink layer and the substrate layer to protect the ink layer and the substrate layer, thereby extending the service life of the edge banding.

[0003] The protective layer is cured by the UV light source in the curing equipment. The photoinitiator in the ink absorbs the ultraviolet light energy, generates free radicals, and initiates the monomer and oligomer reaction and solidifies to form a surface protective layer. At present, the curing equipment uses UV mercury lamps, that is, ultraviolet curing mercury lamps. During the curing process, the ultraviolet curing mercury lamps will generate a lot of heat, which will make the edge banding easily deformed and affect the product quality. Utility Model Content

[0004] Based on this, it is necessary to provide an LED curing edge banding strip to address the problem that the existing UV mercury lamp tube will generate a lot of heat during the UV curing process, which will make the edge banding strip easily deformed and affect the product quality.

[0005] An LED curing edge banding strip comprises a substrate layer, a water-based ink layer and an LED curing coating layer, wherein the water-based ink layer is covered on the surface of the substrate layer, and the LED curing coating layer covers the surfaces of the water-based ink layer and the substrate layer.

[0006] The above-mentioned LED cured edge banding, since the LED curing lamp is a cold light source and has no heat radiation, the surface temperature of the decorative material product irradiated by the light source is low, which can effectively reduce or avoid thermal deformation caused by high temperature during the curing process of the edge banding, thereby effectively improving the production quality of the LED cured edge banding; at the same time, since the luminous intensity of the LED curing lamp is stronger than that of the UV mercury lamp, the curing effect of the LED cured coating layer is better, thereby improving the production quality; the LED curing lamp does not need to be preheated during use, which can save the preheating time and effectively shorten the curing interval time, thereby effectively improving the production efficiency of the LED cured edge banding.

[0007] In one embodiment, the substrate layer is a PVC resin layer or an ABS resin layer.

[0008] In one embodiment, the thickness of the substrate layer is 0.4-3.0 mm.

[0009] In one embodiment, the coating amount of the aqueous ink layer is 15 g / m 2 .

[0010] In one embodiment, the coating amount of the LED curing coating layer is 20g / m 2 . BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1 The substrate layer 10 is a PVC resin layer or an ABS resin layer. The thickness of the substrate layer 10 is 0.4 to 3.0 mm, which makes the LED curing edge banding strip 100 have antibacterial and moisture-proof properties. The coating amount of the water-based ink layer 20 is 15 g / m 2The LED curing coating layer 30 is LED varnish purchased from the market, and LED light is applied to the surface of the substrate layer 10 and the water-based ink layer 20, and the LED varnish is polymerized or cross-linked by the ultraviolet light emitted by the LED curing lamp to promote the curing of the LED varnish. The coating amount of the LED curing coating layer 30 is 20g / m 2 .

[0023] The LED-cured edge banding strip 100 described in this embodiment is prepared by the following method, including the following steps:

[0024] 1) Extruding PVC resin or ASB resin by an extruder to form a substrate layer 10;

[0025] 2) printing a water-based ink layer 20 on the surface of the substrate layer 10, and placing the substrate layer 10 in a dryer for hot air drying to solidify the water-based ink layer 20;

[0026] 3) Roll-coat LED varnish on the surface of the water-based ink layer 20, and then use the ultraviolet light emitted by the LED curing machine to polymerize or cross-link the LED varnish itself, so as to promote the LED varnish to cure to form an LED-cured coating layer 30, and thus obtain the LED-cured edge banding strip 100.

[0027] The working principle of the LED-cured edge banding 100 described in this embodiment is as follows: Since the LED curing lamp is a cold light source and has no heat radiation, the surface temperature of the decorative material product irradiated by the light source is low, which can effectively avoid thermal deformation caused by high temperature during the curing process of the edge banding, thereby effectively improving the production quality of the LED-cured edge banding 100; at the same time, since the luminous intensity of the LED curing lamp is stronger than that of the UV mercury lamp, the curing effect of the LED-cured coating layer 30 is better, thereby improving the production quality; the LED curing lamp does not need to be preheated during use, which can save the preheating time and effectively shorten the curing interval time, thereby effectively improving the production efficiency of the LED-cured edge banding 100.
