Description

Waterproof honeycomb composite board for furniture

technical field

The utility model relates to a composite board for furniture, that is, a multi-layer waterproof honeycomb composite board for furniture.

Background technique

With the rapid development of the furniture industry, the demand for furniture is increasing at a rate of 10-15% per year, and the wood required by the furniture industry is more than 50 million m ³ per year. China is a country with relatively scarce forest resources, especially With the enhancement of people's awareness of environmental protection, how to achieve sustainable development of the furniture industry and expand the range of furniture materials is an urgent problem to be solved. In addition, the relevant paper furniture materials currently on the market have problems such as non-waterproof, easy to deform, excessive harmful substances, and poor strength-to-weight ratio during use.

Utility model content

The utility model is to avoid the deficiencies of the prior art, and provides a waterproof honeycomb composite board for furniture to solve the problem of non-waterproof, large deformation, poor durability, excessive harmful substances, and poor strength-to-weight ratio of existing paper furniture materials. The problem.

The utility model solves the technical problem and adopts the following scheme:

A waterproof honeycomb composite board for furniture, including a paper honeycomb core layer, its structural feature is: the paper honeycomb core layer is the center layer, and a glass fiber cloth layer, a particle board layer and a wood veneer layer are sequentially arranged from the inside to the outside.

The structural features of the utility model also lie in:

The polyurethane adhesive PUR is cold-pressed between the glass fiber cloth layer, the paper honeycomb core layer and the particle board layer.

The glass fiber cloth of the glass fiber cloth layer is alkali-free and wax-free polyester glass fiber cloth.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

1. Both sides of the paper honeycomb core of the utility model are pasted with glass fiber cloth, and the polyurethane adhesive PUR is used for cold pressing. The use of PUR glue can avoid the warping and deformation of the real paper honeycomb core by moisture and heat, and improve its water resistance. Therefore, it can effectively improve the water resistance, strength-to-weight ratio, and dimensional stability of paper furniture materials, and has the advantages of low investment, rich raw material resources, and high production efficiency.

2. The glass fiber cloth of the glass fiber cloth layer of the utility model is alkali-free and wax-free polyester glass fiber cloth, and its beneficial effect is to increase the waterproof performance of the honeycomb composite board. Alkali-free and wax-free polyester fiberglass cloth has the advantages of good deformation resistance, moisture resistance, impact resistance, dimensional stability, mildew resistance, and insect resistance, and is non-toxic and low in price. The strength of alkali-free and wax-free polyester glass fiber cloth is better than that of alkali-containing glass fiber cloth, and the glass fiber and resin after dewaxing treatment have good infiltration and adhesion, and meet environmental protection requirements.

3. The polyurethane adhesive PUR is also used for cold pressing between the glass fiber cloth layer and the particle board layer of the present invention, which can effectively improve the bonding performance and water resistance between the glass fiber board and the particle board.

4. The utility model has the effects of waterproof, moisture-proof, anti-corrosion and insect-proof, and has the characteristics of good dimensional stability, high strength-to-weight ratio, low manufacturing cost, no release of harmful objects, etc. The material is in line with the development direction of my country's sustainable circular economy and has a very broad market development prospect.

Description of drawings

Fig. 1 is a schematic diagram of a transverse cross-sectional structure of the utility model.

Labels in the figure: 1 wood veneer layer, 2 particle board layer, 3 glass fiber layer, 4 paper honeycomb core layer.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, the waterproof honeycomb composite panel for furniture includes seven layers of wood veneer layer 1, particle board layer 2, glass fiber cloth layer 3, paper honeycomb core layer 4, glass fiber cloth layer 3, particle board layer 2, and wood skin layer 1 structure.

In the specific implementation, the glass fiber cloth of the glass fiber cloth layer 3 adopts alkali-free and wax-free polyester glass fiber cloth; the polyurethane adhesive PUR cold pressing is used between the glass fiber cloth layer 3 and the paper honeycomb core layer 4 and the particleboard layer 2 forming.

The waterproof honeycomb composite board for furniture has good water resistance, good moisture resistance, good dimensional stability, no release of harmful substances, high strength-to-weight ratio, and good durability such as anti-corrosion and mildew resistance during use.

Claims (3)
