Embodiment 1

[0017] Embodiment 1 of a melamine impregnated paper veneering multilayer board veneering method: comprises the following steps in sequence: first the surface is sprayed with AL 2 o 3 The melamine-impregnated paper is placed on the multi-layer board bonded with E0 phenolic adhesive and surface-treated, the multi-layer board is placed in the multi-layer board mold base in the press, and the press is closed, and the temperature of the steel plate die is controlled. Between 130°C and 170°C, the pressure of the steel plate die is controlled between 300 tons and 900 tons, and the pressing time of the steel plate die is controlled between 1 minute and 2 minutes. It is preferable to control the temperature of the steel plate die to be 160° C., the pressure of the steel plate die to be 600 tons, and the pressing time of the steel plate die to be 1 minute.

[0018] The multi-layer board with E0 phenolic glue has a formaldehyde emission of 0.04 mg / L, which meets high environmental prote...

Embodiment 2

[0020] A second embodiment of a melamine-impregnated paper veneering multilayer board veneering method: comprises the following steps in turn: first spray the surface with AL 2 o 3 Put the melamine impregnated paper on the multi-layer board bonded with E1 glue or E2 glue or ordinary glue and carry out surface treatment, put the multi-layer board into the multi-layer board mold base in the press, and close the press, The temperature of the steel plate die is controlled between 100°C and 130°C, the pressure of the steel plate die is controlled between 300 tons and 900 tons, and the pressing time of the steel plate die is controlled between 5 minutes and 30 minutes. It is best to control the temperature of the steel plate die to be 110° C., the pressure of the steel plate die to be 600 tons, and the pressing time of the steel plate die to be 15 minutes.

[0021] The formaldehyde content of E1 glue is 0.05-0.09 mg / L, and the formaldehyde content of E2 glue is 0.09-0.20 mg / L. Mul...

Abstract

The invention discloses a method for coating melamine impregnated paper on the surface of a multi-layer board, which sequentially comprises the following steps: firstly, putting the melamine impregnated paper the surface of which is sprayed with AL2O3 on the multi-layer board bonded with glue after surface treatment; then, putting the multi-layer board into a multi-layer board die holder in a pressing machine, and hermetically pressing the multi-layer board by the pressing machine; and after pressing, taking out the coated multi-layer board. The invention has the advantages that the wearing coefficient of the surface sprayed with AL2O3 reaches 2000-6000 revolutions, the method can be used for manufacturing products such as floors, pedals and the like, the pressure is reduced, the wood grains on the surface of the wood and the sand shadow of the substrate can not rebound, and the coated surface is more smooth and attractive.

Description

technical field [0001] The invention relates to a furniture board, in particular to a method for veneering a melamine-impregnated paper veneering multilayer board. Background technique [0002] The boards used in the furniture industry include medium-density boards, high-density boards, and multi-layer boards. Among them, multi-layer boards are widely used by furniture manufacturers because of their high strength and resistance to deformation. In the surface decoration of the board, paint is often used, or PVC wood grain paper, melamine impregnated paper is used for veneer decoration. Using melamine impregnated paper veneer, it has good waterproof and fireproof effect, beautiful and durable, and low cost. It can be directly veneered on the surface of medium density board, high density board and other boards. The reason is that the multi-layer board is generally only treated with paint, and the melamine-impregnated paper cannot be directly veneered. The reason: the multi-lay...
