Description
Technical field
The utility model relates to a kind of interior lining panel, especially relates to the interior lining panel of box car.
Background technology
Box car is the one in railway transport vehicle, and box car is by bottom vehicle frame, and sidewall framework and ceiling composition, box car, also can conveying people time urgent mainly based on the fast freight of commom carrier bag, is called in the past " boxcar ".
Traditional box car does not have liner, afterwards for preventing goods and fork truck in transportation loading and unloading process from, to the damage of car body, adding crashproof interior lining panel in sidewall framework steel frame inside.Early stage crashproof interior lining panel mainly adopts 3mm bamboo slab rubber, but following problem has appearred in bamboo slab rubber in the process used: after (1) uses 2-3, and bamboo slab rubber occurs that water suction is rotted, and needs to change.(2) bamboo slab rubber receives external impacts breakage, and surface there will be bamboo fibre, easily causes damage to goods and personnel.Researchist is to this has been improvement in the industry, and bamboo base lining of railway boxcar plate disclosed in the Chinese utility model patent of application number 201320172576.7 Authorization Notice No. CN203293314U, have higher mechanical property, and expansion rate of water absorption is little.But the bamboo base interior lining panel of this improvement directly adopts shaping bamboo mat, still there is the hidden danger that water suction is rotted.
Have based on this, applicant develops material imputrescibility and has the lining of railway boxcar plate of excellent impact resistance.
Find through retrieval, the Chinese invention patent application of application number 201210456251.1 application publication number CN103806357A discloses a kind of temporary pavement plate, Chopped fiber is adopted to strengthen resin board as sandwich layer, continuous fibre enhancement resin prepreg plate is as top layer, after hot pressing compound, then obtain through coating or hot melt film process.But on the one hand, the application of this temporary pavement plate is road building field, falls far short with the utility model application; On the other hand, this temporary pavement plate thickness is excessive, directly cannot be used as lining of railway boxcar plate, and simultaneously this application gives increases the enlightenment that top layer and core layer thickness can strengthen mechanical property, and therefore researchist directly cannot use for reference the technical scheme of this application in the industry.
Utility model content
The purpose of this utility model is: for above-mentioned prior art Problems existing, proposes a kind of lining of railway boxcar plate, material imputrescibility and have excellent impact resistance energy.
In order to reach above object, the technical solution of the utility model is as follows:
A kind of lining of railway boxcar plate, comprise the upper and lower epidermis through hot pressing composite molding and central layer, central layer is between upper and lower epidermis; Upper and lower epidermis is made up of at least two layers of unidirectional fiber prepreg tape respectively, has 0 degree of-90 angle of spending between the fiber bearing of trend of adjacent two layers unidirectional fibre prepreg tape; The material of unidirectional fibre prepreg tape is that continuous glass fibre strengthens thermoplastic polypropylene resin's composite material; The material of central layer is short fiber reinforced thermoplastic polypropylene resin composite material; The thickness of upper and lower epidermis is respectively 0.5-2.0mm, and the thickness of central layer is 1.5-6.0mm, and the thickness of interior lining panel is 2.5-8.0mm.
In this structure, upper and lower epidermis is by least two layers of unidirectional fiber prepreg tape, form by above-mentioned specific direction, and adopt continuous glass fibre and thermoplastic polypropylene resin in the material of unidirectional fibre prepreg tape, adopt thermoplastic polypropylene resin in the material of simultaneously central layer, the shock resistance of whole interior lining panel can be guaranteed like this within the scope of above-mentioned specific thicknesses.
The perfect further technical scheme of the utility model is as follows:
Preferably, the thickness of unidirectional fibre prepreg tape is 0.2-0.4mm; The thickness of upper and lower epidermis is respectively 0.5-1.0mm; The thickness of central layer is 1.5-4.0mm; The thickness of interior lining panel is 2.5-5.0mm.The thickness of whole interior lining panel can be reduced so further on the basis of guaranteeing shock resistance.
Preferably, the angle between the fiber bearing of trend of adjacent two layers unidirectional fibre prepreg tape is 90 degree.
Preferably, interior lining panel is fixed on box car inwall through rivet and press strip.
After adopting structure of the present utility model, material both can be avoided to rot, good shock resistance can have been possessed again, and then improve durability well; Meanwhile, whole interior lining panel thickness is less, meets the operating needs of box car.
