Description
Technical field
The utility model relates to a kind of glued board, relates in particular to a kind of bamboo-wood plywood.
Background technology
The bamboo carpentry begins starting in China from the nineties, wood substituted by bamboo, and constantly opening up the bamboo wood application is to alleviate forest reserves poorness, an otherwise effective technique measure of improving the ecological environment, the bamboo grove of China is abundant, and speed was given birth in 4 years, utilizes it to replace effective green resource of rainforest timber just.
The patented technology and the corresponding patent application of a lot of relevant bamboo-wood floors have also appearred thus.The utility model patent CN 2661631Y that applied on July 30th, 2003 as the utility model applicant discloses a kind of two-layer at least plank and container bamboo-wood plywood of one deck bamboo clappers at least of comprising, but its plank is located at dash board up and down, and bamboo clappers is located at internal layer, directly glued joint between bamboo individual layer and the bamboo individual layer, the bamboo veneer must impregnation or gluing.Chinese patent CN1569409A also discloses a kind of bamboo alternate composite plate of wood and manufacture method thereof, it comprises the honest and clean and transversely arranged veneer of bamboo of vertical arrangement, bamboo is honest and clean respectively to be combined with each other by table inwards with veneer, bamboo is honest and clean to have following two kinds with complex method veneer: 1, outer honest and clean compound by three layers of bamboo, sandwich layer is honest and clean compound by the alternate two layers of bamboo of individual layer veneer; 2, skin is one deck bamboo mat, and sandwich layer is honest and clean compound by the alternate two layers of bamboo of individual layer veneer, and sandwich layer is that bamboo is honest and clean.It also is the direct compound a kind of assemble pattern of bamboo layer and bamboo layer, and its middle bamboo single plate must impregnation or gluing.
In sum, the domestic and international at present bamboo-wood plywood main feature in the bamboo plywood field is: have the bamboo veneer to contact with the bamboo veneer in the bamboo-wood plywood; All or part of bamboo veneer is carried out preliminary treatment, as bamboo veneer drying-gluing-drying; Hot pressing pressure is big, as greater than 20 kg/cm; Compression ratio is big, as greater than 25%.Therefore, the lower and poor stability of producing of bamboo-wood plywood product quality.
Summary of the invention
The purpose of this utility model is, at the deficiencies in the prior art, provides a kind of bamboo-wood plywood, adopt bamboo curtain splint veneer, Wooden veneer according to certain arrangement mode collocation assembly, the bamboo plywood stock utilization height that produces, production cost is low, product quality height and stable performance.
For achieving the above object, the utility model adopts following technical scheme:
A kind of bamboo-wood plywood, comprise panel, central layer and base plate, form by hot pressing behind the veneer assembly of forming panel, central layer and base plate, described panel and base plate are one deck impregnation bamboo mat, described central layer by the gluing Wooden veneer and not the gluing bamboo curtain splint veneer assembly that is staggered form, wherein, be one deck Wooden veneer at least, accompany one deck Wooden veneer at least between any adjacent two layers bamboo curtain splint veneer of all the other composition central layers near the veneer of described panel and base plate.
Described bamboo-wood plywood wherein, accompanies one deck Wooden veneer between any adjacent two layers bamboo curtain splint veneer of described composition central layer, and perhaps part accompanies one deck Wooden veneer, and part accompanies the above Wooden veneer of one deck.
Described bamboo-wood plywood, wherein, described impregnation bamboo mat and the used glue of gluing Wooden veneer are the waterproof phenol glue.
Described bamboo-wood plywood, wherein, described bamboo-wood plywood panel or base plate also can be provided with one deck decorative layer outward.
The utility model produces described bamboo-wood plywood and production method compared with prior art has following distinguishing feature:
1, the science of bamboo veneer and veneer combination.Always have between the bamboo veneer in the existing bamboo-wood plywood to contact, or bamboo curtain splint and bamboo mat, or bamboo curtain splint and bamboo curtain splint because the gummed characteristics of bamboo veneer itself, in the existing technology to bamboo veneer gluing, pressure hot pressing all is in order to solve the gummed problem between the bamboo veneer greatly.By a large amount of Test Summaries, the utility model adopts the combination of bamboo veneer science, be to accompany one deck Wooden veneer at least between any two-layer bamboo veneer, gummed between bamboo veneer that is difficult to glue together and the bamboo veneer is become gummed between bamboo veneer and the Wooden veneer, so not only solved the bad bamboo-wood plywood quality instability problem that causes of gummed between the bamboo veneer, and can simplify production process, and reduce process time, improve stock utilization.
2, the bamboo curtain splint veneer does not need gluing.Need bamboo mat, bamboo curtain splint gluing in the existing bamboo-wood plywood production, gluing is handled need be to bamboo veneer redrying, production process is many, increase the glue use amount, owing to produce the main material phenol rise in price of phenol glue, cause much producing the bamboo plywood or the stopping production of bamboo-wood plywood producer of building template or closing down at present.Bamboo-wood plywood of the present utility model and production technology thereof, the bamboo curtain splint veneer of forming central layer does not need gluing, not only simplifies production process, and reduces the glue use amount, reduces the bamboo-wood plywood production cost greatly;
3, do not need big pressure hot pressing, hot pressing time is short, and compression ratio is little.Existing bamboo-wood plywood production technology adopts big pressure hot pressing, and generally greater than 20 kg/cm, hot pressing time is long, in the hot pressing blank flat need be in press slow cooling or secondary hot pressing etc., compression ratio is big, usually greater than 25%.Production efficiency is low, and stock utilization is not high, causes production cost very high.Bamboo-wood plywood described in the utility model and production method thereof, adopt less hot pressing pressure, less than 20 kg/cm, hot pressing time is short, the hot pressing of every millimeter assembly thickness is less than 1.5 minutes, and compression ratio has not only improved production efficiency less than 20%, and the stock utilization height, reduced the production cost of bamboo-wood plywood.
Bamboo-wood plywood of the present utility model, bamboo veneer combination science in the bamboo-wood plywood, the bamboo curtain splint veneer does not need gluing, and operation is few, the cost of material is low; Hot pressing time is short, pressure is low, the production efficiency height, and compression ratio is little, the stock utilization height, production cost is low; Product quality is high and stable.
Bamboo-wood plywood described in the utility model will produce revolutionary impact to the utilization of the bamboo resource of China's abundant, for China's bamboo industry is opened up a great scope of land.
