Composite wood-based panel for container floor and manufacturing method thereof

Abstract

The invention discloses a composite wood-based panel for a container bottom plate and a manufacturing method thereof. The method comprises: sorting and arranging the wooden veneers, the moisture content of the wooden veneers is less than 12%, preparing bamboo materials, performing fragment treatment, dispersing and drying, Dry the bamboo curtains and mats until the moisture content is below 15%, coat both sides with 20% to 30% phenolic glue, then age or dry at low temperature, and then heat press to form; the particle board substrate is sanded to a certain thickness as the core board, assembled Blank, wood veneer, bamboo curtain, bamboo mat, resin-impregnated paper materials are used alone or combined with particleboard core board, hot-pressed at high temperature, and then step-down, exhaust, and pressure-relieving, and divided according to size ; The hot-pressed bamboo is cold-pressed into a bamboo square, then dried and solidified, and opened into pieces; the composite wood-based panel includes: a surface layer, an interface layer, and a core layer. The present invention adopts a press-fit structure, no longer relies on multi-layer thick plywood made of hard broad-leaf clones and Abidon, and solves the current situation of insufficient material for the bottom plate of the container.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, in particular to a composite wood-based panel for container bottom plates and a manufacturing method thereof. Background technique [0002] The main load-bearing part of the container is the bottom plate, so the requirements for the bottom plate of the container are very high, and it needs to have high mechanical properties, appearance quality, impact resistance and aging resistance. For a long time, the container manufacturing industry has relied almost entirely on hard broad-leaved clones grown in tropical rainforests and multi-layer thick plywood made of Abidon as bottom plates. Because the growth cycle of this kind of tree species is very long, it generally takes 50 years or even longer. With the over-exploitation of the original tropical rainforest, large-diameter clones and Abidon have become priceless. In order to protect the world's ecological environment and reduce the consump...
