Description

Composite container floor with particle board as core material for structure

technical field

The utility model relates to a composite container bottom plate with particleboard for structure as the core material, and belongs to the technical field of wood-based panel manufacturing in the wood industry.

Background technique

The main load-bearing area of a container is the bottom plate. The container manufacturing industry requires the bottom plate 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 multi-layer thick plywood made of hard broad-leaf clones (Keruing) and Apitong (Apitong) grown in tropical rainforests as bottom plates. Because the growth cycle of this type 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 consumption of tropical hardwood resources, develop new container floors and broaden the source of floor materials. profound practical significance.

Contents of the invention

The purpose of the utility model is to provide a composite container bottom plate with particleboard for structure as the core material. The composite container bottom plate can be made of small-diameter wood, branch wood, and harvesting and processing residues with high longitudinal strength and elastic modulus, and the ratio of strength and elastic modulus in the longitudinal and horizontal directions meets certain requirements, and has high shear resistance. Structural particleboard with cutting performance, which is used as the core material of the container floor. The surface material can be made of wood veneer, bamboo curtain, bamboo mat, resin impregnated paper and other materials, which can be used alone or in combination.

The technical solution of the present utility model: its structure is to take the particle board for structure as the core board, and the upper and lower layer materials each adopt 2-4 layers of wood veneers coated or impregnated with phenolic glue (or other weather-resistant glue); One piece of impregnated paper, one piece of bamboo mat impregnated with phenolic glue (or other weather-resistant glue) and 1 to 3 sheets of wood veneer (or double-sided coated or impregnated with phenolic glue (or other weather-resistant glue)) Use bamboo curtains impregnated with phenolic glue or other weather-resistant glue to replace part or all of the wooden veneers); or use a piece of clone or Abidon wood veneer produced in Southeast Asia from the outside to the inside, or other wood veneers with similar properties, 1 to 3 double-sided coated or impregnated phenolic glue (or other weather-resistant glue) wooden veneers, or replace part or all of the wood veneers with bamboo curtains or bamboo mats impregnated with phenolic glue (or other weather-resistant glue).

The utility model has the advantages of effectively utilizing timbers of different tree species and different diameter classes in my country and all over the world, such as various coniferous timbers, broad-leaved timbers and bamboos of natural forests and artificial forests. Using these materials alone or in combination, through scientific design and reasonable combination, can not only solve the difficulty of hardwood shortage in the world, but also solve the technical problem of mass production of new bottom plates that meet the technical requirements of the international container industry. The special structural particle board is used as the middle core material after being sanded to a certain thickness, and 4-8 layers of wood veneer, bamboo curtain, bamboo mat, resin impregnated paper and other materials are used alone or in combination as the surface material; some wood The veneer needs to be double-coated (or impregnated) with phenolic glue (or other weather-resistant glue), bamboo curtains and bamboo mats need to be impregnated with phenolic glue (or other weather-resistant glue), and resin-impregnated paper is made of wood pulp paper impregnated with phenolic or melamine Or these two mixed resins are made by drying at low temperature. A certain amount of insecticide should be added to these glues, so that it can penetrate evenly into the surface material of the container floor during hot pressing, so that the bottom plate has long-term insect-proof performance; the core material and surface material are combined into a slab , and then hot-pressed and glued to make the container bottom plate, its strength, elastic modulus and other performance indicators can fully meet the technical requirements of the international container industry.
