Description

Waterproof plywood of bamboo wood preparation

Technical Field

The utility model relates to the technical field of plywood, in particular to a waterproof plywood made of bamboo.

Background

The plywood is one of the common materials for furniture, is one of three large plates of an artificial plate, and can also be used as a functional material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other with the grain direction of adjacent layers, and the skins and inner sheets are typically symmetrically disposed on either side of the core or core. The glued veneer is pressed into a board blank which is formed by criss-cross matching of glued veneers according to the wood grain direction under the condition of heating or not heating, the conventional plywood has a simple structure, different mechanical properties in the longitudinal direction and the transverse direction, lower static bending strength and elastic modulus and poorer waterproof performance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a bamboo-wood-made waterproof plywood, which comprises a body plate, wherein a waterproof curved surface is arranged at the top end of a main body plate, the waterproof curved surface is connected with an outer reinforcing layer, the outer reinforcing layer is connected with a back plate, the back plate is connected with a core plate, the core plate is connected with a panel, the panel is connected with an inner reinforcing layer, a waterproof curved edge is arranged on one side of the top end of the main body plate, and clamping grooves and clamping strips are respectively arranged on two sides of the main body plate.

Preferably, the following components: the outer reinforcing layer and the inner reinforcing layer are wood pulp impregnated phenolic paper boards.

Preferably: the back plate and the face plate are wood veneers.

Preferably: the core board is a multi-layer bamboo woven bamboo mat.

Preferably: the surface of the waterproof curved edge is convex, and the waterproof curved edge is made of waterproof plastic materials.

Preferably: the size of the clamping groove is matched with that of the clamping strip, and the clamping groove can be clamped with the clamping strip.

Preferably: the outer reinforcing layer, the back plate, the core plate, the face plate and the inner reinforcing layer are bonded through phenolic resin glue.

Preferably: the waterproof curved surface is a nano self-cleaning waterproof coating, and the waterproof curved surface forms an inwards-concave curved surface structure by setting different spraying thicknesses.

Compared with the prior art, the utility model has the beneficial effects that:

1. the multi-layer bamboo mat has the advantages that the mechanical property is improved and enhanced by arranging the multi-layer structure, the tensile property is greatly improved by arranging the inner core of the multi-layer bamboo woven bamboo mat, and the wood pulp impregnated phenolic paper board has better wear resistance, good demoulding effect and easy production by arranging the wood pulp impregnated phenolic paper board reinforcing layer. The waterproof curved surface and the waterproof curved surface are arranged, accumulated water is gathered to the concave part of the waterproof curved surface through gravity and discharged, and the accumulated water is prevented from being dispersed and permeated into the connecting seam, so that the waterproof performance of the waterproof adhesive is improved, and the phenolic resin adhesive is used for bonding each layer of the waterproof adhesive, so that the waterproof adhesive can still keep better bonding stability in a humid environment, and the applicability of the waterproof adhesive is stronger.
