Packaging type corrugated enhanced laminated veneer lumber and manufacturing method thereof

Abstract

The invention relates to a packaging type corrugated enhanced laminated veneer lumber and a manufacturing method thereof, wherein the packaging type corrugated enhanced laminated veneer lumber structurally comprises a wood veneer and glass fiber cloth, wherein the wood veneer is applied with phenolic resin or urea resin, single spreading is 150-220g / m<2>, the spread wood veneer is assembled with the grain and put in a gum-dipped glass fiber cloth, the warp-direction fiber of the glass fiber cloth is parallel to the fiber direction of the wood veneer, the glass fiber cloth is used as secondary surface layers of the upper side and the lower side of the laminated veneer lumber after being gum-dipped and dried and used for improving elastic modulus and rupture modulus, and the laminated veneer lumber is in a corrugated shape and manufactured by a mould pressing method. The invention has the advantages that quick-growing wood veneers are used as raw materials to manufacture the packaging type corrugated enhanced laminated veneer lumber, once moulding forming is carried out, and the packaging type corrugated enhanced laminated veneer lumber has high strength and good dimension stability, can substitute the existing solid pallet and plywood combined pallets, is applied to the package and transportation fields. The quick-growing wood is utilized, thus reducing logging of natural timber resources and protecting ecological environment.

Description

Technical field [0001] The invention relates to a corrugated reinforced veneer laminated timber for packaging and a manufacturing method thereof using fast-growing tree species wood as raw materials. It belongs to the technical field of man-made panels and composite materials manufacturing technology. Background technique [0002] Every year, my country's packaging and transportation industry needs a large number of pallets, and the main types of pallets used are plastic pallets and wooden pallets. Compared with plastic pallets, wooden pallets have the advantages of light weight, easy processing and low price, so they are widely used. At present, the wood pallets commonly used in my country mainly include solid wood pallets and plywood combined pallets. The raw materials used in solid wood pallets are mostly natural forest coniferous woods, such as larch and mongolica. Solid wood pallets must be fumigated for export packaging, which not only requires cutting down a large amoun...

AI Technical Summary

Problems solved by technology

Solid wood pallets must be fumigated for export packaging, which not only needs to cut down a large amount of natural forest wood, but also increases the cost of packaging and transportation, which not only wastes resources, but also destroys the ecological environment

The plywood combined pallet is made by sawing plywood with a certain thickness and large format into narrow strips, and then assembling it with a nail gun or screws. Export does not require fumigation, but secondary processing is required to make the final product, which increases material consumption, power consumption and labor consumption
