Problems solved by technology

As the floor material of containers, this kind of wood needs several million square meters every year. However, there are not many stocks of this kind of wood in foreign countries, which are not enough for normal use for two to three years. If this continues, it will affect the development of containers.

Embodiment 1

[0014] Use tree branches and broken wood as raw materials, cut off the branches (about 2.5 meters), and prepare according to the following method:

[0015] 1) Put the truncated tree branches into the cooking pool for cooking, slowly heat up to 80-90°C in the pool, keep warm for 22-24 hours, slowly cool down, take out the cooked tree branches, dry in the air (generally dry in the shade), saw and grow ( Wood blocks with a length of 70-90mm, cut (with a slicer) into thin slices with a thickness of less than 2mm, and dry (drying with a drum-type spray heat dryer) to make the moisture content less than 10%;

[0016] 2) Glue sizing: use a drum sprayer for sizing (phenolic glue and triamine glue, etc. can be used);

[0017] 3) Plank planking: (carry out with paving machine) plank plank can be mixed with less than (total amount) 45% bamboo fragments or sawdust etc., generally one layer of bamboo fragments or sawdust one layer of thin wood chips, criss-cross paving (generally every Th...

Abstract

The present invention is one kind of container floorboard of reconstructed sheet and wood chip, and features that the container floorboard is produced with tree branch and wood chip as material and through the steps of: cutting, boiling in a boiling tank, draining, cutting into sheet, drying to water content less 10 %, gluing, crisscross spreading, pre-pressing, hot pressing, planing and polishing, edging and veneering. The present invention provides rich material source for container floorboard, and is favorable to saving timber resource and protecting ecoenvironment.

Description

technical field [0001] The invention relates to the technical field of composite boards, in particular to a container floor with a recombined structure of veneer chips and a preparation method thereof. Background technique [0002] With the development of my country's foreign trade, there are more and more trade exchanges with foreign countries, and the number of container freight is increasing. While the number of containers is increasing, the number of container flooring is more prominent. The container floor needs to be replaced every 7 to 8 years, and the wood used for the floor is high-grade wood, such as cloned wood. This kind of wood needs to be imported from Myanmar. There is not much domestic storage, and it is a tree that is protected by the country. . As the floor material of containers, this kind of wood needs several million square meters every year. However, there are not many stocks of this kind of wood in foreign countries, and it is not enough for normal us...
