Abstract
The utility model relates to an automobile floor with a sandwich structure. A fiber skeleton is embedded in a polyurethane foaming body to increase the toughness of a sandwich layer, and the hardness, strength and firmness of the sandwich layer are ensured through the fusion composite fixed connection between the polyurethane foaming body and a strip-shaped fiber solid body of the fiber skeleton, so when the automobile floor is bent in the use, assembly and transportation processes, the fiber skeleton realizes the function of reinforcing ribs in the polyurethane foaming body of the sandwich layer, the cracking starting from the middle part of the automobile floor is avoided, and further the problem of insufficient toughness of the polyurethane foaming body formed by the foaming of pure polyurethane material in the prior art is solved.
Description
Technical field
The utility model relates to the bus interior technical field, relates in particular to a kind of sandwich construction automotive floor panel.
Background technology
At present, be bamboo adhesive floor with the floor on the automobile, part adopts the aluminium honeycomb floor, bamboo adhesive floor from great, and contain a large amount of solvent-borne type glue, not withstanding corrosion and damaging by worms.The aluminium honeycomb floor is complex manufacturing not only, and has great problem in installation process, and special processing need to be passed through in air exercise screw position.
Application number is that 200820153707.6 Chinese utility model patent discloses a kind of polyurethane fibrilia plastic composite plate material, this sheet material is by just, reverse side top layer and just, the sandwich of layers of sandwiched consists of between the reverse side top layer, wherein just, the reverse side top layer is the flaxen fiber composite layer, sandwich of layers is polyurethane foaming body, thereby so that the floor of using on the automobile has corrosion prevention, mothproof, light and the simple advantage of production process of quality, but because polyurethane foaming body is to be formed by simple polyurethane material foaming, thereby so that the toughness of whole sheet material is not enough, using, easily rupture from the middle part in assembling and the transportation, and then increased the sheet material use, the cost of assembling and transportation.
The utility model content
The utility model provides a kind of sandwich construction automotive floor panel, is intended to improve the toughness of existing automotive floor panel.
Technical scheme of the present utility model is as follows:
A kind of sandwich construction automotive floor panel, comprise the top layer, positive and negative and be in sandwich of layers between the top layer, positive and negative, described sandwich of layers comprises polyurethane foaming body, be embedded with fiber reinforcement in the described polyurethane foaming body, described fiber reinforcement has the clearance space that fibre strip entity and fibre strip splitting object form, described polyurethane foaming body have foam filled in described clearance space and with the compound entity part that is connected of described fibre strip entity melting.
Described positive and negative top layer includes melting and is composite and fixed at the compound filling polyurethane layer of melting on glass base fabric on the described sandwich of layers and the glass base fabric.
Described fibre strip entity is the natural fiber bar.
The utility model strengthens the toughness of sandwich of layers by bury fiber reinforcement underground in polyurethane foaming body, captive joint the hardness that guarantees sandwich of layers by the melting between the fibre strip entity of polyurethane foaming body and fiber reinforcement is compound, intensity and fastness, thereby use at automotive floor panel, the assembling and the transportation in when automotive floor panel generation bending, fiber reinforcement can play the effect of reinforced rib in the polyurethane foaming body of sandwich of layers, avoid automotive floor panel therefrom between the fracture, and then solved the problem of the polyurethane foaming body toughness deficiency that pure polyurethane material foaming forms in the prior art, and because polyurethane foaming body has corrosion prevention and the light characteristics of quality in the utility model, fibre strip entity in the fiber reinforcement has the light characteristics of mothproof quality, and sandwich of layers can realize by foam filled technique during fabrication, thereby so that the utility model also has corrosion prevention, mothproof, light and the simple advantage of production process of quality.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
The embodiment of sandwich construction automotive floor panel of the present utility model: as depicted in figs. 1 and 2, this automotive floor panel is by just, anti-top layer 1,2 and just, anti-top layer 1, the sandwich of layers 3 of sandwiched consists of between 2, wherein sandwich of layers 3 is made of the fiber reinforcement 3-2 that buries underground among polyurethane foaming body 3-1 and the polyurethane foaming body 3-1, and fiber reinforcement 3-2 is made of the clearance space that fibre strip entity and fibre strip splitting object form, described fibre strip entity is the natural fiber bar, the entity part of polyurethane foaming body 3-1 is filled in the described clearance space, and captives joint with the melting of fibre strip entity is compound; Positive and negative top layer 1,2 is composite and fixed on the described sandwich of layers by melting that the compound fixing filling polyurethane layer 5 of melting consists of on glass base fabric 4 and the glass base fabric 4.
The utility model launches two volume glass woven cloth relative spacings when making production, and applies filling polyurethane layer 5 in this two-layer glass woven cloth, to obtain positive and negative top layer 1,2; Simultaneously, between two-layer glass woven cloth, cast polyurethane foaming body 3-1 in fiber reinforcement 3-2, and make polyurethane foaming body 3-1 foaming, to obtain sandwich of layers 3, then with positive and negative top layer 1,2 and sandwich of layers 3 under the pressurize transmission effect of prolonging pressure device, be sent to the following process operation.
Because in the every reduction by 10% of automobile deadweight, but fuel-economizing 6% ~ 8%.And the weight of this automotive floor panel of same thickness is bamboo adhesive floor half, thereby can reduce about vehicle complete vehicle weight 100Kg, can realize the lightweight of passenger vehicle, thereby solved automotive floor panel weight-saving problem, and the polyurethane foaming body 3-1 that strengthens by the natural fiber bar solves general paper honeycomb, the indeterminable installation question of aluminium cellular type core structure.The thickness of this automotive floor panel can carry out free adjustment by sandwich of layers 3, sandwich structure has advantages of light weight and is high-strength, positive and negative top layer 1,2 is adopted glass establishment cloth to strengthen filling polyurethane layer 5 and is obtained, and utilize the adhesiveness of polyurethane material, the realization production process can be realized without gel and serialization, thereby so that production process production efficiency of the present utility model is high, energy consumption is low, does not produce waste water, waste gas.The water absorption rate of this bus deck and thermal conductivity ratio bamboo adhesive floor are low in addition, and heat insulation effect is desirable, and has foaming structure, and the effect of sound insulation and noise reduction is also ideal.
In the above-described embodiments, the fibre strip entity is the natural fiber bar in the fiber reinforcement of sandwich of layers, and in other embodiments, this natural fiber bar also can be used other chemical fibers or the regenerated fiber replacements such as glass fibre bar, flaxen fiber bar.
In the above-described embodiments, the matrix on positive and negative top layer is the glass woven cloth, in other embodiments, the glass woven cloth also can with glass spin other fibre knitting cloths or the spinning replace.
