Description

Bamboo veneer facing vertical core board

Technical Field

The utility model belongs to the technical field of artificial boards, and particularly relates to a bamboo skin veneer vertical core board.

Background

The solid wood board is firm and durable, has natural grains, not only has the unique fragrance of natural wood, but also has better moisture absorption and air permeability, so that the solid wood board is a high-quality board for manufacturing high-grade furniture and decorated houses. However, since the solid wood board is usually made of complete wood, the manufacturing cost is high, the process is difficult, and limited by limited wood resources, the solid wood board is difficult to be widely applied to the fields of furniture manufacturing, house decoration and the like.

Nowadays, in order to meet the experience demand of consumers on solid wood furniture, solid wood skins are bonded on ecological boards in the existing market, so that solid wood feeling can be brought to people. However, at present, the solid wood skin-ecological plate materials existing in the building material household market generally have the following defects:

1. the surface gloss is good, but the solid wood feeling is insufficient. When the ecological plate is manufactured, in order to ensure that the ecological plate has good waterproofness and avoid the ecological plate from being damped and mildewed, the surface of the solid wood skin of the ecological plate is usually coated with a layer of paint. The texture of the solid wood skin can be covered by the paint to a certain extent, so that the surface gloss of the finally prepared ecological plate is good but the solid wood feeling is insufficient, and the aesthetic property of the ecological plate is seriously influenced.

2. Low cost performance and is not healthy and environment-friendly enough. The solid wood peel adhered to the surface of the ecological board is mostly made of high-grade wood such as oak, sandalwood or black walnut, the high-grade wood has long growth period, slow lumber production and low yield, and the solid wood peel made of the tree seeds has higher cost; in addition, the cutting of high-grade wood with long growth period does not accord with the ecological environmental protection idea advocated at present. On the other hand, the solid wood skin is complex in manufacturing process, and after physical and chemical processing, a small amount of toxic and harmful substances generally remain in the solid wood skin, so that the health of consumers is influenced to a large extent.

3. Low transverse static bending strength and poor deformation resistance. When the core board of the ecological board is manufactured, logs are generally cut into core strips, and the core strips are cooled or dried and then spliced into the core board of the joinery, but the deformation of the core strips in the core board along the wood grain direction cannot be limited due to the ecological board manufactured by using the core board with the structure, so that the manufactured ecological board is easy to warp and deform after being used for a period of time, the transverse static bending strength and the surface flatness of the ecological board are affected, and the attractiveness and the use performance of the ecological board are reduced.

Therefore, the vertical core plate coated with the UV paint surface has clear and bright bamboo grains, real reflection, uniform and elegant color and good aesthetic property, and can replace solid wood plates to meet the experience requirements of consumers on solid wood furniture to a great extent.

(3) In the core board, the wood grain direction of the single board is staggered with the deformation direction of the core strip by changing the superposition direction of the single board in the core strip, so that the internal stress in the core board is changed, and the vertical core board substrate can be effectively prevented from being warped and deformed along the wood grain direction of the single board due to long-time use. Therefore, the vertical core plate finally manufactured by the utility model has stable performance, longer service life and better aesthetic property.

And when the square plate cutting core strip is manufactured, the number of the layers of the single plates needing to be superposed and assembled is relatively small, the glue consumption is correspondingly reduced, the processing technology is simple, and the vertical core plate base material manufactured by the single plates has stronger integral layering and better aesthetic property.

(6) According to the utility model, the thermoplastic resin adhesive film is selected to replace an adhesive to bond the upper bamboo skin layer, the upper surface layer, the core plate, the lower surface layer and the lower bamboo skin layer together, so that on one hand, the production process is simpler, the production efficiency can be correspondingly improved, and the cost can be saved; on the other hand, the content of formaldehyde in the product can be reduced, so that the product is free from formaldehyde.

(7) In the vertical core board substrate, the upper surface layer and the lower surface layer adopt a single-layer single-board structure, so that the prepared laminated wood board substrate has better stability and moderate thickness; and the adoption of the double-layer single-plate structure can ensure that the transverse static bending strength of the manufactured core-board substrate is better and the bearing capacity is stronger. Therefore, the joinery board base material can be selectively manufactured according to different requirements, and the finally manufactured ecological board has wider application range.

In conclusion, the cabinet door has the advantages of stable integral structure, strong deformation resistance, straight and natural surface texture and elegant and simple texture, can give solid wood feeling to people, is suitable for the fields of indoor decoration, furniture manufacture and the like, and is particularly suitable for manufacturing cabinet doors such as wardrobes, cabinets, door leaves and the like.
