A kind of oriented structure wood wool board

Abstract

The invention relates to a wood wool slab with a directional structure. Leftovers discarded during wood processing are processed into wood wools, and the wood wools are pressed by adhesive, so as to form a three-layer composite structure. The three-layer composite structure comprises an upper surface layer, a lower surface layer and a core layer, wherein the wood wools of the upper surface layer and the lower surface layer are longitudinally distributed, the length of each wood wool is 40 to 150mm, the width of each wood wool is 2 to 10mm, and the thickness of each wood wool is 0.6 to 1mm; and the wood wools of the core layer are uniformly distributed, and the length of each wood wool is 2 to 40mm. The wood wool slab with the directional structure has the advantages that on the premise of meeting the user requirements, the requirement on the processing raw material is low, the source of the raw material is wide, the leftovers of fir wood, such as slab edges, are fully utilized, the production cost is greatly reduced, the utilization rate of logs is greatly improved, and the environment-friendly value is greatly improved; and the wood wool slab is widely applied to the fields of electromechanical packaging structure materials and furniture decoration slab materials.

Description

technical field [0001] The present invention relates to an oriented mat made of fibers. Background technique [0002] At present, the raw materials used in domestic oriented boards are mainly logs, such as the processing of oriented particle boards, which cannot solve the large amount of waste leftovers generated after the production and processing of a large number of logs, such as sub-small fuelwood, board edge skin, etc.; raw material requirements High, and the source range is narrow, especially for the processing residues of Chinese fir and other woods, which cannot be processed: about 70% of the materials below 60mm will be produced during the processing of Chinese fir. If all of them are treated as waste materials, the cost of raw materials will be obviously high; However, Chinese fir has a benzene-like fiber structure, and it is easy to produce a knife clamping phenomenon during processing, and all the knives are easily broken, and the process performance is poor, and...

[0002] At present, the raw materials used in domestic oriented boards are mainly logs, such as the processing of oriented particle boards, which cannot solve the large amount of waste leftovers generated after the production and processing of a large number of logs, such as sub-small fuelwood, board edge skin, etc.; raw material requirements High, and the source range is narrow, especially for the processing residues of Chinese fir and other woods, which cannot be processed: about 70% of the materials below 60mm will be produced during the processing of Chinese fir. If all of them are treated as waste materials, the cost of raw materials will be obviously high; However, Chinese fir has a benzene-like fiber structure, and it is easy to cause the phenomenon of knife clamping during processing, and all the knives will be easily broken. The process performance is poor, and the processing is difficult.

For example, Chinese invention patent application CN102198684A discloses a kind of directional etching flower flower and its preparation process. It uses the leftovers of rotary-cut veneer in the production process of plywood as raw materials, and is bonded together by an adhesive to form a criss-cross pavement and then pressed. Three-layer structure; however, its raw materials are still limited to the leftovers of rotary cutting veneer, and it is especially not suitable for the processing and utilization of leftovers of Chinese fir. The cost reduction is limited, and the environmental protection value still needs to be tapped
