Embodiment 1

[0042] Embodiment 1. Imitation wood grain melamine paper

[0043] See figure 1 . Plain paper substrate 1 is 80g / m 2 For plain paper, first print the background color and wood grain pattern on the printing machine, dip the plain paper substrate 1 in a solution containing 50wt% melamine formaldehyde resin with a viscosity of 15 seconds, and control the amount of gluing to 150-160g / m 2 The resin solution is then put into 3 sections (4 meters each) for drying in a horizontal oven, the temperature is controlled at 130-140°C, the transmission speed is 20m / min, and then roll-coated on one side of the paper with the melamine adhesive layer 2 impregnated once One layer of UV-curable coating 3 with a thickness of 30um enters a photocuring machine equipped with two 9.6kw UV lamps (high-pressure mercury lamps) and a transmission speed of 20m / min. The other side of the paper is roller-coated with a viscosity of 15 seconds, containing 50wt% melamine formaldehyde resin solution, and the amo...

Embodiment 2

[0045] Example 2. Patterned melamine paper with patterns

[0046] See figure 1 . Plain paper substrate 1 is 120g / m 2 Ordinary paper, first print a pre-designed pattern on the printing machine, immerse the ordinary paper substrate 1 in a solution of melamine-formaldehyde resin with a viscosity of 18 seconds, and control the amount of gluing to 240-250g / m 2 The resin solution is then dried in a 4-section (4 meters per section) horizontal oven, the temperature is controlled at 170-180°C, the transmission speed is 10m / min, and then a layer of thickness is rolled on the paper side impregnated with melamine glue 2 UV-curable coating 3 of 50um enters a photocuring machine equipped with 3 15kw UV lamps (high-pressure mercury lamps) and a transmission speed of 10m / min. After curing, it is rolled on the other side of the paper impregnated with melamine glue 2 once One layer has a viscosity of 18 seconds, contains 60wt% melamine formaldehyde resin solution, and controls the amount of ...

Abstract

The invention belongs to the field of building decoration material, in particular to melamine fumiture surface paper coated with an ultrasonic violet curing coating which is formed by applying the ultrasonic violet curing coating on the surface, and a preparation method thereof. A common paper substrate is dipped into melamine for once and then taken out and dried; and then a layer of ultrasonic violet curing coating is applied on one surface of the common paper dipped with the melamine, and is radiated and cured by ultrasonic violet; and the a layer of melamine is applied on the other surface of the common paper dipped with the melamine and dried, to obtain the melamine fumiture surface paper coated with the ultrasonic violet curing coating. After being coated at high temperature, the melamine fumiture surface paper coated with the ultrasonic violet curing coating obtained through the invention of the invention has the advantages of good adhesion of the surface ultrasonic violet curing coating and the melamine layer and good recoatability of the ultrasonic violet curing coating surface, and has better recoatability than the prior commonly used melamine fumiture surface paper.

Description

technical field [0001] The invention belongs to the field of building decoration materials, in particular to melamine paper coated with an ultraviolet-curable coating obtained by coating the surface with an ultraviolet-curable coating (UV coating for short) and a preparation method thereof. Background technique [0002] At present, the general production method of melamine paper is to dry ordinary paper after dipping in melamine glue once, and then apply a layer of melamine glue on the front and back of the paper impregnated once with melamine glue, and then dry it. Melamine paper is mainly used for lamination on the surface of decorative boards such as density boards and particle boards. The laminated boards are widely used in the production of various furniture, cabinets and other interior decoration materials. Melamine resin is a kind of resin with very stable chemical properties. Because the melamine glue pre-coated on the surface of melamine paper is cured to form a fil...
