Wainscot method of melamine impregnated paper wainscot multi-layer board

Abstract

The invention discloses a multilayer board face-sticking method adopting pieces of melamine-dipped paper. The method includes the following steps: 1. a piece of melamine-dipped paper is placed on a multilayer board which is through surface treatment; 2. the multilayer board is put in a multilayer mould seat in a pressing machine, a steel plate pressing-mould on the pressing machine is pressed downwards, the temperature of the steel plate pressing-mould is controlled between 100 and 130 degree centigrade, the pressure of the steel plate pressing-mould is controlled between 900 and 1100 tons, and the pressing time of the steel plate pressing-mould is controlled between 2 and 5 minutes; 3. the pressing is stopped at a regulated pressing time, and the multilayer board the face of which has been stuck. The multilayer board which has the face stuck with pieces of melamine-dipped paper and is made by the face-sticking method has simple technique and quick manufacturing speed, and largely reduces the material and manufacturing cost of the multilayer boards with the faces stuck by pieces of melamine-dipped paper.

Description

technical field [0001] The invention relates to furniture boards, in particular to a method for veneering multi-layer boards with melamine-impregnated paper. 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-layer boa...

Problems solved by technology

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-layer board is composed of bark rolled from layers of trees, and the moisture content inside is high. In the prior art, the temperature of the pasting should be around 180°C or higher, a certain period of time (30 seconds to 50 seconds), and a certain pressure to complete the veneering. Multilayer boards are veneered under such high temperature conditions When there is a strong airflow, it is easy to blow up the board and the steel plate die, and the multilayer board is easily deformed and twisted at high temperature

Therefore, to increase the melamine-impregnated paper veneer on the surface of the multi-layer board, the existing method is generally to first set up a medium density board on the multi-layer board, and then carry out the veneering of the melamine-impregnated paper on the MDF, so that the multi-layer board It will not be affected by high temperature and avoid the above-mentioned problems caused by direct veneering, but the use of intermediate density boards for transition increases multiple process steps, not only greatly increases the cost of raw materials, but also greatly increases the manufacturing cost, and the production speed is limited. Restricts, and thus limits the consumer market for melamine-impregnated paper-clad multilayer panels
