Description
Technical field
The present invention relates to a kind of 3D textile floor installation method used for rail vehicle, 3D textile floor and preparation method thereof.
Background technology
At present domestic trolley coach and highway passenger vehicle used floor more adopt bamboo slab rubber, bamboo slab rubber low price,
But its density is bigger than normal, one ten meters about its bamboo slab rubber consumption of highway passenger vehicle is up to 200 kilograms；Although bamboo slab rubber can simultaneously
Reach the flame-retarding characteristic of laws and regulations requirement, but in the larger intensity of a fire or can burn, thus bamboo slab rubber is not optimal fire-retardant
Flooring material.Also there is part passenger vehicle to adopt aluminium sheet as flooring material, but aluminium sheet itself is partially soft, poor rigidity, is not suitable for directly making
For flooring material, its ameliorative measure has two, and one is to be combined with other materials, and two is to be spelled using extruded aluminium section plate
Connect, but both floor panel structures all can lead to floor to be laid particular stress on, and is unfavorable for lightweight vehicle body.
Foamed aluminium board is applied on bus deck as a kind of new material and is had broad prospects, and it meets bus deck
Required rigidity and intensity, there is light-weighted effect, also there are preferable noise reduction and insulative properties, particularly it can not simultaneously
Aptitude to burn is more beneficial for providing valuable escape time for passenger in a fire.
As Chinese patent Authorization Notice No.：CN2726982Y, authorized announcement date：On September 21st, 2005, entitled《Foam
Aluminum floor compartment》Utility model patent in it is proposed that a kind of Foamed aluminium wagon floor, it includes surface layer and sandwich of layers, make
The side of the base plate for surface layer and panel scribbles glue-line, and the foamed aluminium board as sandwich of layers is placed between two-layer glue, heating pressure
Form Foamed aluminium wagon floor after system.The use of this Foamed aluminium wagon floor not only can intercept track and road surface effectively to car
The noise of transmission and vibrations in railway carriage or compartment, improve the comfortableness taken, and can mitigate car body deadweight；Meanwhile, foamed aluminium compartment ground
Plate ageing resistance is strong, intensity is high, do not burn, and is a kind of new material of safety and environmental protection.But, foamed aluminium board is on bus deck
Application there is also problems with：
Firstth, mounting process is poor, because its surface can not carry larger pressure, the edge part of foamed aluminium board when laying is installed
Divide and be not fixed easily, be not as so easily operated as bamboo slab rubber.
Secondth, between panel, core, boundary strength is poor, easily produces layering；
3rd, after low velocity impact, the easy unsticking in interface lost efficacy, and easily extension of losing efficacy；
4th, can not one-shot forming, quality stability control more difficult.
Sandwich is the version that composite is commonly used, and the mode of its transmission load is similar to I-beam, i.e. surface layer
Bear bending load, core bears shear-type load.By integrated optimization, sandwich material can be by with the way of most economical,
Little deadweight, reaches rigidity and the intensity of maximum.Sandwich mainly includes honeycomb sandwich construction composite, foam folder at present
Rotating fields composite and overall 3D hollow interlayer composite material.3D double glazing steel floor mounting means on stainless steel car body
Lack ripe scheme.If borrowing the mounting means of current aluminum honeycombfloor, by the way of pre-buried section bar or aluminium block, in 3D
Empty fiberglass one-shot forming technique difficulty is larger, relatively costly.Therefore according to 3D double glazing Steel material, rustless steel bassinet structure body
The new floor mounting means of feature exploitation is very necessary.
