Description

A thick core solid wood ecological board

technical field

The utility model relates to a thick-core solid wood ecological board, which belongs to the technical field of wood processing.

Background technique

The traditional ecological board is composed of multi-layer high-quality solid wood boards and beautiful, environmentally friendly and wear-resistant fabrics. The ecological board is more and more favored and recognized by consumers due to its beautiful surface, convenient construction, ecological environmental protection, scratch resistance and wear resistance. . With the popularity of panel furniture in the family, ecological panels have been widely used in home decoration, panel furniture, cabinet wardrobes, bathroom cabinets and other fields. However, the existing ecological board is made of 9 to 11 layers of veneers bonded by adhesives, which has the problems of wasting raw materials and high production costs. In addition, due to the increase of the adhesive layer, the formaldehyde emission is greatly increased, and the environmental protection level decline.

The Chinese utility model patent with the patent number of 2015201552451 provides a kind of thick core solid wood ecological board, including the central pine core board, the eucalyptus core board pasted and fixed on the upper and lower sides of the pine wood core board, and the The poplar core board and the poplar skin pasted and fixed on the outer surface of the poplar core board, the 5-layer core board plus two surface layers can reach the thickness of the traditional ecological board, which not only saves the production cost, but also reduces the consumption and reduces the formaldehyde emission. . But because eucalyptus is a kind of fast-growing wood, it is not tough, light in weight, and is easy to crack and deform during processing; and the mechanical strength such as static bending strength, elastic modulus, and screw-holding force of the finished product is relatively poor, resulting in a short service life.

Utility model content

The purpose of the utility model is to provide a thick-core solid wood ecological board, which has excellent processing performance and mechanical performance, zero formaldehyde and no pollution, good moisture-proof effect and long service life.

The thick-core solid wood ecological board includes a central three-layer pine core board, a poplar core board fixed on the outside of the pine core board with an adhesive, and a poplar skin fixed on the outer surface of the poplar core board with an adhesive.

The adhesive is a modified soybean protein adhesive.

The thickness ratio of the three-layer pine core board is 1:1:1.

The thickness ratio of the pine core board, poplar core board and poplar skin is 5.5-11:2:1.

The thickness of the pine core board is 0.5-0.55cm.

The thick-core solid wood ecological board has a bonding strength value of ≥0.7MPa, an elastic modulus of ≥5000MPa, and a static bending strength of ≥40MPa.

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

1. Reduce the number of layers of ecological board and reduce the amount of glue used, which not only reduces the production cost, but also saves time, labor and effort;

2. Modified soybean protein is used as adhesive, no formaldehyde release, safe to use;

3. With three layers of pine core boards with the same thickness as the center, the structure is more balanced, the product stability is higher, and the service life is longer. Moreover, there will be no cracking, warping and deformation during processing, and the processing performance is excellent.

4. The utility model adopts the whole board seamless assembly, and the glue strength, static bending strength, elastic modulus, screw holding force and other performances are excellent; the finished product is tested by the national standard GB/T17657-2013, and the glue strength reaches the national class II According to the standard requirements, the detection glue strength value is ≥0.7MPa, the elastic modulus is ≥5000MPa, the static bending strength is ≥40MPa, and the water resistance reaches the second type moisture-proof level.
