Abstract
The utility model relates to a multilayer artificial board with a bamboo plate cover, which is made of bamboo and / or wood. The utility model is characterized in that the surface material is bamboo chips and the sandwich layer material is bamboo rags or / and rotary cutting wooden boards, and the utility model is formed by hot compacting for one or two times. The utility model has the advantages of science and reasonable product structure and high synthetic utilization of bamboo, the bamboo utilization reaches over 90%, and the utility model also provides wide prospect for the machining and utilization for the fast wood.
Description
The utility model belongs to the wood-based plate manufacturing technology in wood, the bamboo product.
Nearly ten years, the research of China's bamboo processing utilization and production have had development rapidly, there are several hundred families in national various bamboo plywoods, summer sleeping bamboo mat, bamboo parquet floor, bamboo hygienic chopsticks factory and other bamboo processing enterprise at present, what these enterprise's utilization rate of bamboo were high also only can reach about 40%, low is 20~30% only, has a large amount of industrial wood wastes to be used; Also have the bamboo tip, bamboo branch after a considerable amount of dwarf bamboos and bamboo wood are felled also to need to study the new approach that utilizes in addition.
The bamboo of big footpath level can be processed into bamboo plywood (CNZL 87100368) and various types of bamboo product.Dwarf bamboo and bamboo surplus material of processing can be processed into bamboo shaving makes the bamboo crushed aggregates plate.But because bamboo wood contains more starch and protein, therefore, the as easy as rolling off a log generation of bamboo crushed aggregates is gone mouldy.At present, though Many researchers is all being sought the mildew-resistant technology and the mould inhibitor of bamboo wood, and has obtained many progress, do not see as yet so far real effectively, practical, inexpensive mildew-resistant technology and medicament.Therefore, the product of at present domestic bamboo shaving board (or bamboo crushed aggregates plate) factory because the mildew-resistant technology does not reach a standard, mostly is in stopping production or half end-of-life state.Also have, the large tracts of land fast-growing, high-yield woods that China built in the plains region over past ten years all enters the period of felling in turn.In general, the mechanical property of these fast growing woods is all lower, is used for the manufacturing structure glued board, also is difficult to meet the requirements at aspects such as intensity.
Purpose of design of the present utility model is for the industrial wood waste that makes full use of bamboo wood, bamboo plywood factory and a large amount of fast growing woods, the bamboo chip clad can wood-based plate that exploitation is used as the high-strength structure material, alleviate bamboo crushed aggregates as far as possible and easily produce the mechanical property defect of insufficient of going mouldy, and bring into play the advantages of high strength of bamboo wood own as far as possible with fast growing wood.
Technical solution of the present utility model is, is skin-material with the bamboo chip, is core material with bamboo crushed aggregates and/or rotary-cut veneer, uses adhesive and makes bamboo chip clad can wood-based plate by after hot-forming once or twice.
Embodiment 1:
The structure and the manufacturing of once hot-forming individual layer bamboo chip clad can bamboo particle wood-based plate:
As shown in Figure 1, top layer bamboo chip (1) is split into the bamboo chip of about 2~4 millimeters thick, 30 mm wides with mao bamboon, in order to reduce the slit of bamboo chip side, mills flat the bamboo chip side or planing before the jigsaw assembly, and is dried to moisture content and is lower than 8%; The bamboo chip cemented surface is carried out gluing to the employing phenolic resin glue or impregnation processing back is stand-by;
Sandwich layer bamboo particle (2) adopts bamboo shaving that produces in the bamboo processing or the bamboo particle that is processed into dwarf bamboo.The bamboo particle is dried to moisture content is lower than 6%, spray glue with phenolic resin glue and handle, resin added is advisable with 8~12%;
According to the needed thickness of product, make face, backboard with bamboo chip, carry out promptly obtaining after once hot-forming behind the assembly as shown in Figure 1 bamboo chip clad can wood-based plate with quantitative bamboo particle as sandwich layer.
The typical technology parameter of individual layer bamboo chip clad can wood-based plate is as follows:
Product thickness: 12~25mm

As shown in Figure 2, the processing of top layer bamboo chip (1) and sandwich layer bamboo particle (2) is with embodiment 1.Between top layer bamboo chip and sandwich layer bamboo particle, increase one deck rotary-cut veneer (3), with behind the double spread of veneer according to the needed thickness of product, make face, backboard with bamboo chip, carry out promptly obtaining after once hot-forming behind the assembly as shown in Figure 2 bamboo chip clad can wood-based plate as sandwich layer with veneer and quantitative bamboo particle.
The typical technology parameter of individual layer bamboo chip clad can veneer, bamboo particle wood-based plate is as follows:
Product thickness: 14~30mm
Density: 0.80~0.90
MOR: vertically 〉=100MPa, laterally 〉=40MPa
Elastic modelling quantity: vertically 〉=9000MPa, laterally 〉=4000MPa
Embodiment 3:
The structure and the manufacturing of once hot-forming double-deck bamboo chip clad can veneer wood-based plate:
As shown in Figure 3, the processing of bamboo chip (1) is with embodiment 1.The number of plies of rotary-cut veneer (3) can require to determine (being 3 layers of veneer of use among the figure) according to product thickness.Behind the cemented surface gluing with bamboo chip and veneer (3), promptly obtain double-deck bamboo chip clad can wood-based plate after the assemble pattern of employing as shown in accompanying drawing 3 is once hot-forming.
The typical technology parameter of double-deck bamboo chip clad can veneer wood-based plate is as follows:
Product thickness: 12~30mm

Present global freight transportation is all developing to containerzation. Owing to must guarantee that the base plate of container has as far as possible high intensity and elastic modelling quantity in design, 1220 * 2440 * 28mm large format glued board that existing container bottom board all adopts the big footpath in Southeast Asia and the torrid zone, Africa level log to produce is made. Along with tropical rain forest large tracts of land in the world wide disappears, resource worsening shortages, rise in price. Since the reform and opening-up, world container manufacturing industry center of gravity is transferred to China, and there is container plant (Sino-foreign joint venture) family more than 20 in the whole nation at present, the annual need with more than base plate 10 ten thousand steres, all dependence on import. Artificial board with bamboo plate cover takes full advantage of the characteristic of bamboo wood intensity height, good rigidly, makes surface material with bamboo chip, in order to bear bigger External Force Acting; Sandwich layer then adopts low intensive veneer or bamboo particle to make packing material, can utilize low-intensity veneer price low and bamboo particle consumption glue amount is lower, the advantage that do not need mildew-resistant to process as sandwich layer, can reduce product cost, and make the strength and stiffness of finished product satisfy container to the requirement of base plate. Therefore, artificial board with bamboo plate cover had both had scientific and rational product structure, can improve the bamboo wood comprehensive utilization ratio again, and utilization rate of bamboo can reach (drying shrinkage and hot pressing loss are disregarded) more than 90%, and also the processing and utilization for a large amount of fast growing woods provides wide prospect.
