Abstract
The present invention relates to a manufacturing method of recombined bamboo-glued boards, which belongs to the manufacturing technology of the glued boards in artificial board industry. The method uses bamboo as raw materials, and the recombined bamboo-glued boards are formed by truncation, rolling processing, drying, gum dipping, drying, assembly and hot pressing. The present invention is mainly characterized in that rolling processing adopts the following processing method: the green killing of the bamboo is firstly carried out; then, the dissection of the bamboo is carried out; the bamboo is rolled into bamboo bundles which are not fractured in the transverse direction and are loose and connected in the longitudinal direction in the criss-cross without disturbing the fiber arrangement directions of the bamboo. The bamboo-glued boards manufactured by the method have the advantages of high strength, high utilization rate and low cost, and the recombined bamboo-glued boards which can be used for mould boards for building, platform floors, decorative materials, wood for furniture, floors, etc. are favorable engineering structure materials.
Description
(1) technical field
The present invention relates to a kind of production process of recombined bamboo-gluing board, belong to the glued board manufacturing technology in the wood-based panel industry, Patent classificating number is B27D.
(2) background technology
China is located in world bamboo distribution center producing region, and the bamboo grove area ranks first in the world.According to statistics, the whole nation has 5,000,000 hectares of the bamboo grove gross areas now, accounts for the 1/4-1/5 of world's bamboo grove gross area.The whole nation has bamboo grove to distribute or the province (district) of cultivation reaches 27, has only Heilungkiang, Jilin, Inner Mongolia Autonomous Region, Xinjiang Si Sheng not to have bamboo grove to distribute or outdoor cropping.Abundant bamboo timber resource provides reliable raw material basis for the processing and utilization of China, and the bamboo processing and utilization level of China is in the first place in the world always.Since the seventies, successively developed products such as bamboo mat plywood, bamboo weaving bamboo plywood, bamboo wood laminate, bamboo plywood, bamboo floor, bamboo-wood plyboard, be widely used in fields such as building, vehicle, packing, decoration, furniture.But the bamboo plywood of present industrial employing, most of utilization rate of bamboo is lower, only is 20～40%, and a large amount of industrial wood waste and dwarf bamboos are not fully used, and cause the wasting of resources, and the artificial bamboo board production cost is higher, lacks competitiveness.Simultaneously, open bar because of bamboo material adopts, to cut open cutting way such as the thin bamboo strip and process, to have reduced bamboo wood intensity.In addition, it is big that existing bamboo plywood also exists resin added, complex manufacturing, and manual operations is many, problems such as difficult quality control.As in patent of invention CN1020319, a kind of manufacture method of bamboo plywood is disclosed, adopting the big footpath mao bamboon of diameter 〉=50 millimeter is raw material, through inside and outside ring of past, subdivision, poach, wax operations such as flattening, planing operation, dryness finalization, the gluing pressing plate again that boils, pressurizes; Among the patent of invention CN1037295, disclose the manufacture method that a kind of bamboo glue amasss into plate, bamboo has been cutd open behind the thin bamboo strip, oven dry, the impregnation superimposed press plates again; Among the patent of invention CN1093314, disclose a kind of production method of bamboo plywood, bamboo has been hacked, selects, knitted behind curtain, drying, the impregnation pressing plate again.Above patent all exists aforesaid defective.Therefore research and develop a kind of utilization rate of bamboo height, intensity height, technology new product simple, with low cost and just become the task of top priority.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of utilization rate of bamboo height, intensity height, good processability, simple, with low cost, the broad-spectrum bamboo plywood manufacture method of technology are provided.
Technical solution of the present invention is as follows:
Select for use the mao bamboon of 3 years living above diameter≤80mm or early small diameter bamboos such as bamboo, Ph. bambusoides be raw material, be cut into the bamboo section by the press breadth, go blue or green machine or sandblast to go blue or green machine to go green grass or young crops with bamboo wood, poor to solve the bamboo strip wettability, the difficult problem of glue performance difference.Again with after cuing open bamboo machine subdivision, with the bamboo wood rivet bucker bamboo wood is rolled into laterally do not rupture, vertically loose and staggered continuous bamboo bundle, do not upset the bamboo fiber orientation, keep the bamboo wood fundamental characteristics.Then the bamboo bundle is made recombined bamboo-gluing board through operations such as super-dry, impregnation, drying, assembly, hot pressing.
The subdivision process is split into two halves for removing blue or green bamboo wood with cuing open the bamboo machine.Described glue is phenolic resins or Lauxite.Recombined bamboo-gluing board can be pressed into plain plate, bamboo mat cladding boards, bamboo mat, melamine and resin impregnating paper cladding boards and veneer, melamine and resin impregnating paper cladding boards according to user's needs.
Recombined bamboo-gluing board with this method manufacturing has many good qualities.Its utilization rate of bamboo height: it is a raw material with mao bamboon, small diameter bamboo, and raw material sources are extensive, and utilization rate of bamboo can reach more than 90%; Physical and mechanical property is good: the intensity height, and hardness is big, and is crooked hardly, do not ftracture, and material is even; Good processability: can before dyeing, sanding, covering with paint, all need not pass through preliminary treatment with firm of common bamboo timber machining machine and tool saw, plane, mortice opening, ailing, gripping etc.; Smooth surface also can be carried out processing such as veneer, facing; Technology is simple, and required process equipment and plant area are also less; And with low cost, be good structural timber.Recombined bamboo-gluing board can be widely used as building template, platform floor, ornament materials, furniture woods, floor etc.
