Infinite-arbitrary-length bamboo chip integrated material and manufacturing method thereof

Abstract

The invention discloses an infinite-arbitrary-length bamboo chip integrated material. The infinite-arbitrary-length bamboo chip integrated material is formed by a plurality of lengthened bamboo chipswhich are glued and overlaid; each lengthened bamboo chip is formed by a plurality of bamboo chip units which sequentially and continuously mesh and are connected in a butt joint mode; sharp teeth andgrooves are formed in the two ends in the length direction of the bamboo chip units, wherein the sharp tooth of each bamboo chip unit and the groove of the corresponding bamboo sheet unit are matchedto form a meshing butt-joint part, and the meshing butt-joint parts of the adjacent lengthened bamboo chips are arranged in a staggered mode; and the thickness of the bamboo chip units is 4-12 mm, and the width of the bamboo chip units is 15-50 mm. The invention further provides a manufacturing method of the bamboo chip integrated material. The manufacturing method comprises the steps of preparation of the bamboo chip units, meshing butt-joint, hot-pressing gluing and the like. The infinite-arbitrary-length bamboo chip integrated material and the manufacturing method thereof have the advantages that connectors are small, the mechanical strength is uniform, and the infinite-arbitrary-length bamboo chip integrated material is suitable for structures such as van truck bottom plates.

Description

technical field [0001] The invention relates to the technical field of biomass composite materials for box-type trucks, in particular to a composite material with unlimited and arbitrary length bamboo chips and a manufacturing method thereof. Background technique [0002] At present, hardwoods are mainly used as the floor of box trucks in the world, such as cloned wood from tropical rainforests or cold zone hardwoods, etc., but with the rapid development of the global transportation industry, hardwoods with a long growth cycle can no longer meet the needs of box truck floors. At the same time, as hardwood resources become less and less, hardwood resources are in short supply and expensive, which increases logistics costs. Therefore, it is an urgent requirement of the times to find a substitute for hardwood to manufacture a box truck floor. [0003] As a rich renewable resource, bamboo has the advantages of fast growth, high output, and good wood replacement. It is one of th...

Problems solved by technology

But there has been no good production technology to solve this problem. There have been attempts to use finger-jointed panels to achieve a certain length of length, but because the bamboo pieces are too small and too thin, the finger-joint equipment cannot be directly lengthened. Bamboo slices need to be processed into larger cuboids first, and then finger-jointed with pressure at both ends. This production technology has many defects: first, high cost; second, there are obvious interfaces; third, First, the length is still limited, and cannot be infinitely long; fourth, it is inevitable to have large color difference; fifth, the interface is large, and the mechanical strength of the board surface is uneven
