Description

A kind of composite board processing method

technical field

The invention relates to the technical field of composite boards, in particular to a processing method for composite boards.

Background technique

Composite boards in the current market have become one of the flooring varieties favored by consumers in recent years. It not only has the dimensional stability and comfortable foot feeling of traditional wood boards, but also has the high wear resistance of reinforced boards. At the same time, you can choose various An imitation decorative pattern and various textures or textures.

Existing composite board comprises decorative layer, substrate layer and core material layer, and its existing manufacturing method is as follows:

First, brush a layer of liquid glue (generally white latex) on the front and/or back of the core material layer, and after the base material layer is stacked on the front and/or back of the core material layer, the base material layer and the core material layer Put them together into a hot press for pressurization and heating for 8-15 minutes to solidify the liquid glue, and bond the base material layer and the core material layer to form a blank slab; then, put the blank slab into the cold press for cooling and forming ; Then, the blank slab and the decorative layer are laminated and pressed by a hot press to form a composite sheet. In addition, according to processing requirements (such as printing and texture), it can be formed in advance on the steel plate of the hot press that presses and forms the composite sheet. Corresponding protrusions and/or grooves of the printing or texture can be pressed on the surface of the decorative layer to form the required printing or texture when the large board and the decorative laminate are laminated into a composite board.

But the existing method of making this composite board has the following deficiencies, such as: 1. The decorative layer is thinner, the blank slab is thicker, and the time for the cup material slab to be evenly heated to the required temperature is longer. It takes a long time for the machine to make the decorative layer and the blank large plate pressed together (under a certain pressure and temperature). If the pressing time is long, it will easily lead to carbonization of the decorative layer, and if the pressing time is too short, then The bonding strength between the decorative layer and the blank slab is low, and quality problems such as delamination are prone to occur. 2. Liquid glue is used for solidification and bonding. During the cooling and forming process of the cold press, part of the water sol will overflow on the edge of the blank slab, and the overflowing glue needs to be cleaned, resulting in long processing time, complicated processing procedures, and high corresponding costs. .

Contents of the invention

The main purpose of the present invention is to propose a processing method for composite boards, aiming to provide a composite floor with good wear resistance, difficult delamination and stable structure.

In order to achieve the above object, the present invention proposes a processing method for a composite plate, comprising the steps of:

S1. Put the decorative layer and the base material layer on top of each other and put them into a single-layer hot press for pressing to form a decorative panel;

S2. Sticking a solid adhesive film on the front and/or back of the core material layer by a film sticking machine or manually;

S3. Put the core material layer 3 with the solid adhesive film and the decorative panel on top of each other and put them into a hot press for pressing to form a composite board.

The technical scheme of the present invention first laminates the thinner base material layer and the decorative layer, which can better control the temperature, pressure and time during pressing, and shorten the decorative layer while ensuring the bonding strength between the decorative layer and the decorative panel. In order to prevent carbonization of the decorative layer; in addition, the solid adhesive film is heated and softened by a hot press to bond the decorative panel to the core material layer. The bonding strength is high, the structure is stable, and the process is simple. , there is no need to use a cold press to cool the molding as in the existing production method, and there is no step of cleaning the glue on the edge of the formed plate, which can save production time, improve efficiency, and save costs.

The invention provides a processing method for a composite plate.

In the embodiment of the present invention, as shown in Figures 1 to 3, the processing method of the composite plate comprises the following steps:

S1. Put the decoration layer 1 and the base material layer 2 into a single-layer hot press after being stacked to form a decorative panel; generally, the thickness of the base material layer 2 is obviously smaller than that of the core material layer 3 and the base material in the existing production method The blank slab formed by pressing layer 2 is, for example, generally only a fraction of the thickness of the blank slab. When the thinner base material layer 2 and the decorative layer 1 are pressed together, the temperature during pressing can be better controlled. , pressure and time, in the case of ensuring the bonding strength of the decorative layer 1 and the base layer 2, greatly shorten the pressing time of the decorative layer 1 and the base layer 2, thereby preventing the carbonization of the decorative layer 1.

S2. Paste the solid adhesive film 10 on the front and/or back of the core material layer 3 by a film laminating machine or manually, such as a floor (single-sided) or a furniture composite board (double-sided);

S3, stacking the core material layer 3 with the solid adhesive film 10 and the decorative panel into a hot press (generally a multi-layer hot press) for pressing to form a composite board. First, the heat press machine softens the solid adhesive film 10 by heating to bond the decorative panel to the core material layer 3. The bonding strength is high, the structure is stable, and the process is simple. After the bonding is formed, it does not need to be used like the existing production method The cold press is cooled and formed, so there is no step of cleaning the glue on the edge of the formed plate, which can save production time, improve efficiency, and save costs.

Specifically, in step S1 , it also includes the process of forming printing and/or textures on the decorative layer 1 by preforming the embossed steel plate with protrusions or grooves.
