Description

A kind of bamboo offset plate

Technical field

the utility model relates to a kind of bamboo offset plate, is specially a kind of offset plate of the bamboo as use such as building template, platform floors.

Background technology

at present, the utilization of bamboo offset plate is more and more extensive, its production technology is also more various, the Chinese utility model patent that is 2325455 as publication number discloses a kind of Bamboo and wood veneer board, its upper and lower surface layer is the bamboo structure sheaf of curtain-type solid matter, core formed of wood between surface layer is that the overlapping wood chip glue of the multilayer more than two layers connects layer, the perhaps bamboo curtain splint layer of the one or more layers of reinforcement of alternate embedding in core formed of wood, can be so as to adjusting the intensity of Bamboo and wood veneer board, be beneficial to the broaden application scope, be suitable for building template, boxboard, partition plate, floor, decorative panels etc. are many-sided to be used, certainly, in some technique, core formed of wood also can replace with bamboo layer, make the bamboo offset plate of pure bamboo, the offset plate layer of structure of this type that interweaves is more and the more generation of chi structure gap degree is larger, globality a little less than, thereby intensity, the aspect of performances such as toughness are relatively poor, and it is comparatively loaded down with trivial details to manufacture technique, the Chinese invention patent small diameter bamboo bamboo offset plate that a kind of bamboo offset plate of the Chinese invention patent that and for example publication number is 1907666 and manufacture method thereof and publication number are 1386616, the former bamboo wood material of this bamboo offset plate of two types is through processing, cut open sheet or cut open silk, what adopt is the second layer, the 3rd layer of thin bamboo strips used for weaving, Guan Weisu is intensive on the one hand, to connect effect better for this material glue on the other hand, make bulk strength improve, but bending strength, anti-impact force intensity can not meet the place that this respect is had relatively high expectations, and use for a long time top layer easily to break.

The utility model content

the purpose of this utility model is to provide that a kind of intensity is higher, toughness is better, and globality is strengthened, and the physical properties such as bending resistance, resistance to compression are more superior bamboo offset plate also.

above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of bamboo offset plate, comprise bamboo wood layer, intermediate layer and lower bamboo wood layer, the upper surface in intermediate layer and lower surface carry out matsurface glue with the upper surface of the lower surface of upper bamboo wood layer and lower bamboo wood layer respectively and are connected, the machine direction in intermediate layer is vertical with the machine direction of lower bamboo wood layer with upper bamboo wood layer respectively, intermediate layer comprises the multilayer bamboo wood, between each layer of bamboo wood, by matsurface glue, connects; Matsurface glue connects and to refer to bamboo material surface is processed into to the matsurface with tear mark, spreads glue on matsurface, and the mode by hot pressing makes between bamboo wood to form syndeton; Tear mark is that the part bamboo silk by tearing equably bamboo material surface off forms.

in technique scheme, by arranging of three-layer type, make the bamboo fiber of every layer arrange towards same direction, and intermediate layer is vertical respectively with the machine direction of upper and lower bamboo wood layer, and do not adopt arranging of multiple layer interleaving type, the tensile force of all directions of arranging although interweave is improved, it is poor that but glue connects effect, and easily produce gap, globality is poor, density is high not enough, intensity can not reach higher requirement, and in this scheme, though intermediate layer is the multilayer bamboo wood, but machine direction unanimously distributes, by carrying out carrying out glue even after rough surface processing, globality is improved, be not easy cracking, certainly in compression process, ground can be arranged tightr, can greatly improve panel density, coordinate again the connection of upper and lower bamboo wood layer, make bulk strength follow the connection effect all to be greatly enhanced, upper and lower bamboo wood layer is also to be connected by matsurface glue with intermediate layer in addition, make the connection effect better.

as technique scheme preferably, the lower surface of the upper surface of upper bamboo wood layer and lower bamboo wood layer is bamboo strip or surf green brush finish; To be that bamboo strip brush is blue or green process the face that the reserve part surf green forms in the surf green brush finish, and surf green tissue tight, matter are hard and tough, can greatly promote toughness and the intensity of bamboo offset plate.

as technique scheme preferably, the upper surface in intermediate layer is the surf green brush finish, the lower surface in intermediate layer is yellow bamboo face, and each layer, intermediate layer upper and lower surface is the circular order of surf green brush finish, yellow bamboo face, surf green brush finish, yellow bamboo face from top to bottom successively arranges, and this bamboo offset plate global density is 800kg/m ³ -1500 kg/m ³ , on the one hand, toughness and intensity that surf green can improving product, on the other hand, surf green is viscose glue not too easily, and content too much can affect the adhesion effect, thereby reduces the fastness of product, so or need to brush away a part of surf green, to meet the needs of bonding.

as technique scheme preferably, each of intermediate layer layer surf green brush finish, following 1mm thickness place, surface, surf green weight accounts for the 1%-20% of gross weight, in the situation that guarantee bond effect preferably, can make again the performance of product, comprise that the physical properties such as intensity, toughness have lifting preferably.

as technique scheme preferably, upper surface and the lower surface of middle bamboo wood layer are yellow bamboo face, more traditional way, effectively viscose glue, mainly meet product fastness preferably, is applicable to specific place.

above-mentioned bamboo offset plate has following advantage: density can reach 800kg/m ³ -1500 kg/m ³ , intensity and toughness are highly improved, and fastness also can arrive preferably to be controlled, and in addition, comprises that the physical properties such as bending resistance, resistance to compression are all corresponding to obtain larger raising.

in sum, the utlity model has following beneficial effect:

1, adopt common mao bamboon material, aboundresources, cheap, production cost is lower;

2, integral body presents the structure of three-layer type, the structure more in the past woven, and globality is strong, and firmness is better, is not easy to produce problems of crack;

3, the detail analysis surface comprises the processing such as coarse processing, brush surf green, make the bamboo offset plate after completing, bond effect is better, the performance such as intensity and toughness improves, the physical property such as bending resistance, resistance to compression also obviously promotes thereupon, makes rise appreciably service life, from another angle, can also suitably reduce as required glue consumption, not only reduce cost but also reduced the impact on environment;

4, bamboo wood is carried out to other auxiliary processes such as drying, make product more stable in process of production, reduced the problems such as material cracking, explosion, the total quality of product also obtains higher lifting.
