Abstract
The invention discloses a natural fiber composite rail train floor which comprises an intermediate layer, a wood board layer and a face board layer. The intermediate layer consists of a soundproof layer and fibrilia glue-free plywood on two sides of the soundproof layer, and the wood board layer and the face board layer are adhered through adhesives and sequentially arranged on two sides of the intermediate layer. The fibrilia glue-free plywood is composed of fibrilia, polypropylene, flame retardant and polypropylene surface activity treating agent. The plywood made of fibrilia and polypropylene composite serves as a base material for the composite floor, dependency of floor manufacture on solid wood materials is weakened; the static bending strength and elasticity modulus of the floor are evidently improved as compared with those of floors in the prior art, so that the floor is less prone to deformation; and by the aid of the soundproof layer arranged in the composite floor, noise in carriages can be lowered.
Description
Technical field
The present invention relates to train finishing material field, be specifically related to a kind of natural fiber composite rail train floor.
Background technology
Along with the develop rapidly of railway traffic, also more and more higher to the requirements for quality of train interior trimming parts.The quality of train interior trimming parts depends primarily on its composite base material.Floor composite base material many employings solid wood board or PP wood flour board in traditional train.Generally speaking, the timber utilization rate of solid wooden floor board is only 30% ~ 40%, and therefore, adopt solid wood board to be can use a large amount of logs to do raw MAT'L as the shortcoming of composite base material, the dependence for this non-renewable resources of solid wood is stronger; From the counter-bending damage capability of train composite rail train floor of the prior art and MOR and elasticity poor, along with the raising day by day of floor manufacturing technology, higher requirement be it is also proposed to the MOR of row floor for automobile and modulus of elasticity; In addition, with phase mutual friction on track in train traveling process, be directly passed in compartment by vehicle body, passenger stays and wherein can feel that noise is very large, can produce human discomfort.Therefore, be necessary to improve train floor panel structure of the prior art.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, design a kind of natural fiber composite rail train floor, the veneer sheet that the base material employing flaxen fiber of this composite rail train floor and polypropylene composite material are made, reduces the dependence of floor manufacture to solid wood material; The MOR on this floor and modulus of elasticity floor more of the prior art are significantly improved, not yielding; In composite rail train floor, sound isolating layer is set, contributes to the noise reduced in compartment.
For achieving the above object, technical scheme of the present invention provides a kind of natural fiber composite rail train floor, it is characterized in that, described composite rail train floor comprises the interlayer be made up of the flaxen fiber Binderless binding plate of sound isolating layer and described sound isolating layer both sides, described interlayer both sides are disposed with plank layer and panel layer respectively, bonding by adhesives between described plank layer and panel layer.
Preferred technical scheme is, described flaxen fiber Binderless binding plate comprises flaxen fiber and polypropylene, and the percentage by weight that described flaxen fiber and polypropylene account for described flaxen fiber Binderless binding plate is respectively: flaxen fiber 52% ~ 55%, polypropylene 45% ~ 48%.
Preferred technical scheme can also be, also comprise fire retardant and polypropylene surface active treating agent in described flaxen fiber Binderless binding plate, in described flaxen fiber Binderless binding plate, the percentage by weight of each component is respectively: flaxen fiber 52% ~ 54%, polypropylene 45% ~ 47%, fire retardant 0.5% ~ 2%, polypropylene surface active treating agent 0.5% ~ 1%.
Preferred technical scheme can also be, described polypropylene surface active treating agent is cationic surfactant.
Preferred technical scheme can also be, described cationic surfactant is organosilicon cationic inhibiter.
Preferred technical scheme can also be, described fire retardant is organic fire-retardant.
Preferred technical scheme can also be, described sound isolating layer is netted nonwoven fabrics.
Preferred technical scheme can also be, described sound isolating layer is made up of two-layer netted nonwoven fabrics, and the grid of described two-layer nonwoven interlocks superimposed.
Advantage of the present invention and beneficial effect are:
The veneer sheet that the base material employing flaxen fiber of this composite rail train floor and polypropylene composite material are made, reduces the dependence of floor manufacture to solid wood material;
The plank layer of this composite structure densification and panel layer little to moisture absorption amount, reduce floor and to make moist mouldy probability;
With the addition of polypropylene surface active treating agent in substrate plywood, effectively can improve the surface adhesion force of acrylic plastering, make to mix between its with flaxen fiber evenly, contribute to strengthening the density of base material, significantly improve the MOR on this floor;
Substrate plywood is owing to adopting polymer poly propylene as the packing material between flaxen fiber, and modulus of elasticity is significantly improved, and ground slab integral is not easily out of shape;
The sound isolating layer with some small spaces be formed by stacking by two-layer nonwoven is set in composite rail train floor, train run at high speed in orbit produce sympathetic response sound by Sound insulation floorings effect, reduce the noise in compartment, contribute to the comfort strengthening passenger.
