Abstract

The present invention relates to artificial board producing technology. The recombined bamboo-gluing board is produced through the processes of cutting, rolling process, in which bamboo is first cut to eliminate its green part, then rolled into ordered bamboo fiber bundle. The bamboo-gluing board thus produced has high strength, high material utilization and low cost, and may be used in building framework, base board of carriage, decroative material, furniture, etc.

Description

Production process of recombined bamboo-gluing board

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.

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.

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.Glue can be selected urea-formaldehyde resin adhesive and phenolic resin glue as required for use.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.

Manufacture method of the present invention will further specify by the following examples and accompanying drawing.

Description of drawings:

Fig. 1 is spreading bamboo bundle schematic diagram.

Fig. 2 is three layers of recombined bamboo-gluing board schematic diagram.

Embodiment:

Breadth is the manufacture method of the building template of 1220 * 2440 * 12mm with the recombined bamboo-gluing board (see figure 2):

1. raw material is prepared: selecting diameter more than lifes in 3 years for use is that the path mao bamboon of 30-50mm is a raw material.

2. block: the bamboo section that mao bamboon is cut into 2500mm and 1300mm.

3. go green grass or young crops: go blue or green machine to go green grass or young crops with bamboo wood the bamboo section.

4. spreading: will go bamboo section behind the green grass or young crops to be rolled into laterally not rupture, vertically loose and staggered continuous bamboo bundle (see figure 1) with the bamboo wood rivet bucker.

5. dry: the bamboo mat of bamboo bundle and purchase is dried to moisture content below 15% under 100 ℃ of temperature.

6. impregnation: bamboo bundle that drying is good and bamboo mat flood 2-3min in solids content is the phenolic resins glue of 25-30%.

7. dry: as bundle of the bamboo behind the impregnation and bamboo mat to be carried out redrying, under 50-80 ℃ of temperature, be dried to moisture content 10-15%.

8. assembly: impregnation, dried bamboo bundle and bamboo mat are formed five laminate bases, and bamboo bundle head by size is staggeredly placed, and outside outer bamboo bundle was vertically placed, green grass or young crops faces, intermediate layer bamboo bundle was laterally placed, the bluish yellow face is towards interconnected, and top layer and bottom are bamboo mat.

9. hot pressing: will organize good slab and send into press and carry out hot pressing, the cold cold technology that goes out of advancing is adopted in hot pressing, and hot pressing pressure is 3Mpa, and hot pressing temperature is 140 ℃, and hot pressing time is the 1.0min/mm thickness of slab, dockboard under 80 ℃ of temperature.

Recombined bamboo-gluing board with the method manufacturing has many good qualities. Its utilization rate of bamboo height: it take mao bamboon, small diameter bamboo as Raw material, 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, Hardly crooked, do not ftracture, material is even; Good processability: can be with common bamboo wood processing machine tool saw, plane, mortise Groove, nail nail, grip firm etc., before dyeing, sanding, covering with paint, all need not pass through preliminary treatment; Smooth surface also can be carried out The processing such as veneer, facing; Technology is simple, and required process equipment and plant area are also less; And with low cost, be good worker The journey structural material. Recombined bamboo-gluing board can be widely used as building template, platform floor, ornament materials, furniture woods, floor Deng.
