Abstract
The invention relates to a floor board mainly made of bamboo, in particular to a car compartment floor board, which comprises longitudinal grained bamboo curtains, transverse grained bamboo-strip reinforcing bars, a longitudinal bamboo curtain, phenolic impregnated paper and bamboo mats. The large-width bamboo-based artificial board is used as the car compartment floor board, and compared with wood floor boards, the bamboo-based car compartment floor board has the advantages that bamboo resources are rich and sustainable in use after being harvested once, mono bamboo can be felled for use after growth for 5 years, sympodial bamboo in south China can be felled for use after growth for 2-3 years, Dendrocalamus sinicus with fine performance is used as raw material, and accordingly the mechanical property of the car compartment floor board can further be improved by more than 30%.
Description
Technical field
What the present invention relates to is to be the base plate that main raw material(s) is made with the bamboo wood, relates in particular to the automobile bodies base plate.
Background technology
Automobile bodies is because of the needs of bearing goods, requires that base plate has that very high mechanical property, presentation quality, impact resistance, wear-resisting, anti-worm are rotten, fast light photograph and performance such as ageing-resistant.For a long time; The automobile bodies base plate mainly is to utilize high-quality hardwood timber and glued board to make; The high-quality timber resources of China is day by day rare at present; How keeping by import, timber also exists easy hygroscopicity, strain cracking in addition, rotten, the natural flaw such as wear no resistance of damaging by worms, and adds that the various defectives (like knot, swirls etc.) in the arboreal growth process cause the inhomogeneous of quality; The plate face width degree of timber also receives the restriction of the age of tree, so timber is restricted as automobile bodies base plate and breast board.Bamboo plywood and thin bamboo strips used for weaving Strength of Plywood are high, wearability is good as the platform floor history of existing more than ten years; But most board material splices of small breadth that use form; When design and installation, adopt bottom girder, the fixing mode of Multipurpose screw added; Be prone to see seam crossing because of the moisture expantion defective such as be uneven that seems, operating position is not satisfied.
Summary of the invention
According to the deficiency of prior art, the invention provides a kind of new departure of making the automobile bodies base plate with the large width bamboo wood composite board of reinforcement.When this large width bamboo wood composite board is made platform floor, can add reinforcement in the place of no bottom girder according to the design in compartment, this reinforcement is to add together at assembly, once hot-forming getting final product.Adopt this significantly base plate, some compartment with a big plate just can, can make the design of compartment bottom girder more reasonable, assembling is simpler, the set-up time shortens greatly.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals:
A kind of large width bamboo base automobile bodies base plate with reinforcement comprises vertical texture bamboo curtain splint and cross grain bamboo chip reinforcement, also comprises vertical bamboo curtain splint, hard paper and bamboo mat.
As preferably, be followed successively by the vertical bamboo curtain splint of one deck from top to bottom, the vertical texture bamboo curtain splint of one deck; One deck cross grain bamboo chip reinforcement, the vertical texture bamboo curtain splint of one deck, one deck cross grain bamboo chip reinforcement; Five layers of vertical texture bamboo curtain splint, one deck cross grain bamboo chip reinforcement, the vertical texture bamboo curtain splint of one deck; One deck cross grain bamboo chip reinforcement, the vertical texture bamboo curtain splint of one deck, the last vertical bamboo curtain splint of one deck.Vertical bamboo curtain splint, dipping phenol glue and attractive in appearance through low temperature drying for the top layer, this bamboo curtain splint is preferably whole bamboo curtain splint, vertical spreading not, and the thickness of bamboo curtain splint is no more than 1.5mm; Vertical texture bamboo curtain splint dipping phenol glue and through low temperature drying; Two ends and centre the 60～80mm of three places cross grain bamboo chip reinforcement is arranged longitudinally at slab, lay respectively at the inside of the second layer and the 3rd layer of vertical texture bamboo curtain splint, play a part reinforcement.
As preferably, be followed successively by one deck hard paper from top to bottom, one deck bamboo mat, the vertical texture bamboo curtain splint of one deck; One deck cross grain bamboo chip reinforcement, the vertical texture bamboo curtain splint of one deck, one deck cross grain bamboo chip reinforcement, five layers of vertical texture bamboo curtain splint; One deck cross grain bamboo chip reinforcement, the vertical texture bamboo curtain splint of one deck, one deck cross grain bamboo chip reinforcement; The vertical texture bamboo curtain splint of one deck, one deck bamboo mat is one deck hard paper at last.Bamboo mat dipping phenol glue and through low temperature drying; Vertical texture bamboo curtain splint dipping phenol glue and through low temperature drying; Two ends and centre the 60～80mm of three places cross grain bamboo chip reinforcement is arranged longitudinally at slab, lay respectively at the inside of the second layer and the 3rd layer of vertical texture bamboo curtain splint, play a part reinforcement.
A kind of manufacturing approach of the large width bamboo base automobile bodies base plate with reinforcement, its processing step branch:
A, veneer, bamboo curtain splint, bamboo mat sorting and arrangement; The assortment of veneer is poplar, pine, Eucalyptus, is dried to moisture content≤10%, is coated with phenol glue as required; And bamboo curtain splint, bamboo mat done to moisture content below 12%, low temperature drying to moisture content is below 18% after flooding phenol glue;
B, assembly and hot pressing, with top layer bamboo mat or bamboo curtain splint or the veneer mode spreading through overlap joint to the length that needs, then with sandwich layer bamboo curtain splint or veneer and bamboo curtain splint assembly; Add reinforcement in the stressed two bottom girder middle that reach more greatly of need; When assembly, add 2～3 layers of wide cross grain thin bamboo strips used for weaving of 60～80mm reinforcement near the table backing layer; It is 135～150 ℃ in temperature then; Maximum pressure is to carry out hot pressing under the condition of 2.0～4.0MPa, keeps 12～35 minutes, then steam discharge, water flowing cooling and release.
Advantage of the present invention: with large width bamboo base wood-based plate as the automobile bodies base plate; Compare with timber and to have many advantages; At first bamboo timber resource is abundant, and bamboo resource has and once cultivate successfully, gets final product the advantage of continuous utilization; The mao bamboon material generally can be cut down utilization in growth after 5 years, and the bamboo that grows thickly of southern area just can be cut down utilization in 2～3 years.There is abundant fast growing wood resource in China, and like poplar, Eucalyptus, pine etc., bamboo base platform floor mechanical property is superior to general hardwood and thin bamboo strips used for weaving glued board.As with the Dendrocalamus sinicus of better performances as raw material, its mechanical property can also improve more than 30%.Because adopt the upper and lower surfaces of the high thin bamboo curtain splint of intensity at plate, sandwich layer adopts veneer or bamboo curtain splint, makes composite board not only have higher mechanical property, also solved bamboo curtain splint and processed problem loaded down with trivial details and the output supply shortage.Owing to be that large format is installed, thus there is the bottom girder quantity in compartment to reduce, and the quantity of the screw of fixed base plate can reduce, and also can improve installation effectiveness.The plate face is smooth, seamless in addition.As posting with hard paper on the top layer, the sheet material of making need not paint, just can directly use, and is particularly suitable for not having the box car railway carriage or compartment and uses.
