Description
Technical field
The utility model belongs to wood processing technique field, and in particular to one kind is suitable in automobile wagon box or train wagon
The fire-retardant bamboo sheet plywood that portion uses.
Background technology
It is well known that willow is fast-growing tree species, adaptable spy wide, growth period in year is long and speed of production is fast
Point has an extensive plantation in the south in China and the north, and Poplar Resource is therefore cheap compared with horn of plenty；But due to poplar
Itself wooden quality is softer, fibre structure is loose, timber is relatively poor and mutability etc., and the scope of application is limited by larger,
Therefore less expensive；Moso bamboo is that Chinese cultivated is long, area is most wide, economic value also most important bamboo kind.The use of moso bamboo
Way it is closely bound up with daily life, people's food, clothing, housing and transportation, sight, with, decorations various aspects play an important role,
It possesses numerous functions such as timber-used, edible, medicinal, ornamental, feeding, environmentally friendly, and growth is rapid, is one in pollution-free green treasure-house
Bright jewel is the ideal species for building green bank；The pole type of moso bamboo is coarse, and due to from self-characteristic, generally using
In for building, such as beam column, frame, scaffold, as plank use then dosage it is smaller, therefore its less expensive；At present
The plank that automobile wagon box or train wagon inside use in the market has price is high, complex manufacturing technology and service life are low to lack
It falls into, has seriously affected the reduction of logistics cost.
Utility model content
There is provided the purpose of the utility model is to overcome defect in the prior art a kind of simple structure and reasonable design,
Manufacture craft is convenient and efficient, of low cost, stability is good, be unlikely to deform, anti-pressure ability is strong, support force is big, is not easily broken, can have
Effect improves the physical property of plank and the fire-retardant bamboo sheet plywood of service life.
What the purpose of this utility model was realized in：It is staggered structure including plate in plate in four layers of poplar and three layers of bamboo chip
At plate includes several small bamboo plates and kernmantle in bamboo chip, and the length of small bamboo plate is：2.5m, width 1.5cm, thickness
For 1.5mm；It is equipped with adhesive layer in adjacent poplar in plate and bamboo chip between plate.
Preferably, the length of plate is in plate and bamboo chip in the poplar：2.5m, width 1.26m, thickness 1.5mm.
The utility model have simple structure and reasonable design, manufacture craft is convenient and efficient, of low cost, stability is good, no
It is yielding, anti-pressure ability is strong, support force is big, the physical property that is not easily broken, plank can be effectively improved and service life it is excellent
Point.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of plate in the utility model bamboo chip.
Specific implementation mode
As shown in Figure 1, 2, the utility model is plate 1 and three layers of bamboo in a kind of fire-retardant bamboo sheet plywood, including four layers of poplar
Plate 2 is staggered composition in piece, and plate 2 includes several small bamboo plates 3 and kernmantle 4 in bamboo chip, and the length of small bamboo plate 3 is：
2.5m, width 1.5cm, thickness 1.5mm；It is equipped with adhesive layer 5 in adjacent poplar in plate 1 and bamboo chip between plate 2.The poplar
The length of plate 2 is in plate 1 and bamboo chip in wood：2.5m, width 1.26m, thickness 1.5mm.
A kind of preparation method of fire-retardant bamboo sheet plywood, includes the following steps：
Step 1：Slicing：Moso bamboo slicing is become into several small bamboo plates 3, the length of small bamboo plate 3 is：2.5m, width
For 1.5cm, thickness 1.5mm；
Step 2：Flame retardant treatment：By several 3 bundlings of small bamboo plate after slicing in step 1 and it is put into fire retardant
Pressurized tank in carry out flame retarding process processing；Several poplar items that plate 1 in poplar is made are also positioned at fire retardant
Pressurized tank in carry out flame retarding process processing；
Step 3：It is dried：By in step 2 after flame retardant treatment small bamboo plate 3 and poplar item be respectively put into baking
It is dried in dry machine, the moisture weight percentage of small bamboo plate 3 and poplar item after drying is no more than 12%；
Step 4：Braiding：Small bamboo plate 3 after being dried in step 3 is put into braider, in length and breadth by kernmantle 4
Small bamboo plate 3 is staggeredly woven into plate 2 in bamboo chip, the length of plate 2 is in bamboo chip：2.5m, width 1.26m, thickness are
1.5mm；
Step 5：Prepare plate 1 in poplar：Poplar item after being dried in step 3 is made plate 1 in poplar, plate 1 in poplar
Length be：2.5m, width 1.26m, thickness 1.5mm；
Step 6：Glue：Five cereals biology powder is added into five cereals biogum, binder, five cereals biogum and five cereals life is made
The weight ratio of object powder is 2：1；
Step 7：Gluing group plate：In lower three layers of poplar in the top of plate 1 and three layers of bamboo chip the top of plate 2 spread it is viscous
Agent is tied, plate 2 in plate 1 in lower three layers of poplar and three layers of bamboo chip is staggered after putting together, is spreading the upper of binder
Plate 1 in the poplar of upper layer is placed at 2 top of plate in layer bamboo chip, and group plate is completed；The amount of spreading of binder is 320~350g/m2；
Step 8：Cold-press adhesion is shaped：To carrying out cold pressing sizing to plank after the completion of the group plate described in step 7；To plate
The pressure of material is 10~13kg/ cm2；
Step 9：Hot pressing：Plank after Cold-press adhesion is shaped carries out hot pressing, and fire-retardant bamboo sheet plywood semi-finished product are made；

Step 10：Finished product：Make fire-retardant bamboo sheet plywood semi-finished product by sanding process, overlay process, cutting edge process and
After polishing process finished product.
What plank prepared by the utility model was mainly prepared according to the characteristic of moso bamboo and poplar itself, by small bamboo plate
3 and poplar item be put into the pressurized tank of addition fire retardant and carry out flame retardant treatment, it is wooden loose due to poplar, can make fire-retardant
Agent more enters the inside of poplar to reach good flame retardant effect, drying and processing can be carried out after flame retardant treatment, at drying
Small bamboo plate 3 is woven into plate 2 in bamboo chip after reason, and plate 1 in poplar is made in poplar item by conventional method；Aforesaid way energy
The loose characteristic of the more soft fibre structure of poplar itself quality is enough efficiently used, fire retardant and the possible poplar inside that enters is made to reach
To preferable flame retardant effect, the elasticity and flexibility of moso bamboo are preferable, can be with the mutability of poplar and the defect phase of easy fracture
In conjunction with to effectively improve the stability and other physical properties of plank entirety, being unlikely to deform and be not easily broken to reach
Purpose；In addition, by moso bamboo slicing at small bamboo plate 3, and plate 2 in bamboo chip will be prepared by the method for braiding, and pass through cold pressing
And hot pressing can effectively improve the stability and anti-pressure ability of plank entirety, be used to reach the support force of plank and extend
The purpose in service life.Five cereals biogum and five cereals biology powder described in the step of above-mentioned preparation method six are purchased fertile in Zhengzhou one hundred
Biological material Co., Ltd, CompanyAddress are：Lu Yuqi Yuan Lu intersections southwest side is built in Henan Province Yingyang City；Since it can
Directly to purchase on the market, therefore repeat no more.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
