Abstract
The utility model relates to an improved passenger car chassis, which is formed by adopting plastic or rubber plastic panel to be compounded with polyurethane with an intensified layer by foaming. The utility model has the advantages of low height, good strength, corrosion resistance, and long service life. Being taken as a passenger car chassis, the utility model is characterized by sound isolation, shock resistant damp, good feet feeling, water resistance and humidity resistance, light self-load etc., which is an ideal carriage chassis material for passenger car. Regulated polyurethane formulations can be used for producing various carriage chassis of large, medium and small size passenger cars to meet different demands.
Description
Technical field
Utility model relates to a kind of car, passenger car box plate, especially a kind of composite bottom board.
Background technology
Passenger vehicle railway carriage baseboard material as various large, medium and small type chassis of bus, has veneer sheet, plastics or rubber and plastic panel and sham wood scutum (as board fiber board, various density artificial board) compound two big classes usually at present.Yet this two class is mainly by the wooden carriage bottom plate that constitutes, and its main deficiency is: the one, and water absorption rate is bigger, and long-term use is subject to suction and rots, thereby service life is not long, and 2-3 need change; Secondly, this type of base plate is nonelastic substantially, and comfort is not strong.Chinese patent 94229940 discloses a kind of automobile-used, by foam polyvinyl chloride or the surface layer that does not foam, polyethylene or polypropylene type semi-rigid foam sheet basic unit and polyvinylchloride or the composite floor board pad of polyurethane plastics bottom by boning and form mutually.Though this car mat has water-fast damp proof insulation, advantage such as sense of touch is good, it can not be independently uses as the base plate of load-bearing.Chinese patent 98114310 disclosed a kind of sandwiched damping board for chassis of bus, be to be formed by stacking by veneer sheet-damping panel-veneer sheet, this plate has only strengthened the elasticity comfort, yet because its two sides still is a wooden plywood, the wood based panel easily rotten vice proper of suction does not obtain eradicating yet.Chinese patent 99224038 disclosed a kind of glass-felt plastic car floor are assembled by the glass steel bar of metal shaped steel and band hollow, and its deficiency is, the one, and cost is higher relatively, and the 2nd, Heavy Weight has increased automotive dead weight power and has expended.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of light weight intensity height is provided, and elasticity and bearing are all good, and it is rotten to be difficult for suction, the passenger vehicle composite bottom board of long service life.
The utility model purpose realizes that main the improvement is that base plate adopts plastics or rubber and plastic panel and the composite panel of being made up of the polyurethane foam board of enhancement layer.Specifically, utility model passenger vehicle composite bottom board by panel with substrate is compound forms, is characterized in that said panel is plastics or rubber and plastic thin plate, and said substrate is the polyurethane foam board that enhancement layer is arranged.Consider factors such as cost, intensity, both thickness ratios are 1: 4-1: 10 is comparatively suitable.Utility model passenger vehicle composite bottom board, its intensity by adjusting polyurethane formulations and thickness, can obtain the various semihard bubble base plates that meet the demands mainly from polyurethane foam board.Enhancement layer in the said polyurethane foam board of utility model, the similar reinforcing bar in cement of main effect, improve the stiffness and the rupture strength of polyurethane foam board, the various flexible filament or the cloth shape layer that combine with polyurethane foam board surface layer and/or internal layer be can adopt, as polyurethane foam board surface layer or internal layer glass fibre, woven roving, short felt, the continuous felt etc. cut of combination with it are laid on.
The utility model composite bottom board, its surface layer and polyurethane foam substrate, it is little all to have a water absorption rate, and water-tolerant, thereby has overcome the easy water absorbing defective of employing sham wood scutum, but also has saved a large amount of natural timbers; The polyurethane foam board of band enhancement layer, it is not high to have overcome general polyurethane foam board intensity again, the defective of rupture strength difference; Both utilize the foaming combination, have omitted the use adhesive agent again.Thereby, the utility model composite panel, have in light weight, intensity good, withstanding corrosion, long service life, makes chassis of bus, has sound insulation, heat insulation, the damping damping, feel is good, waterproof is moisture resistance, characteristics such as self load is light are a kind of desirable passenger vehicle carriage bottom plate materials.Adjust polyurethane formulations, increase enhancement layer and thickness, can produce the composite bottom board of various intensity and fracture resistance, good springiness,, be used for various large, medium and small passenger vehicles to satisfy different demands.
Below in conjunction with two indefiniteness embodiment, further specify utility model.
Description of drawings
Fig. 1 is the utility model first embodiment composite bottom board structure scheme drawing.
Fig. 2 is the utility model second embodiment composite bottom board structure scheme drawing.
The specific embodiment
Embodiment 1: referring to Fig. 1, composite bottom board by modified rubber PVC panel 1 and foamed polyurethane layer 2, fiber reinforcement bottom 3 through foaming compound the composition.Wherein plastics or rubber and plastic panel are thick is 1-5mm, the thick 1-5cm of polyurethane base plate, and the three reaches firm connection by the polyurethane foam layer of centre.During preparation, first lay one deck syntheticfibres and/or fiber cloth and/or felt on the frame baffle plate are poured into a mould the polyurethane slurry of proportioning on request again in framed, go up PVC panel and die face plate again, and heat temperature raising makes its curing, and the demoulding promptly gets above-mentioned composite bottom board.
Embodiment 2: referring to Fig. 2, as embodiment 1, panel adopts the surface that the plastics or the rubber and plastic boards of small embossment 4 are arranged.Remove this, the utility model enhancement layer can also be in polyurethane foam layer upper strata and/or centre, or adopts enhancement layer more than two layers, and these are all true uses novel protected scope.
Claims (5)
1, a kind of improved passenger vehicle composite bottom board is characterized in that said panel is plastics or rubber and plastic thin plate, and said substrate is the polyurethane foam board that enhancement layer is arranged.
2,, it is characterized in that said panel and substrate thickness ratio are 1: 4-1: 10 according to the described passenger vehicle composite bottom board of claim 1.
3, according to claim 1 or 2 described passenger vehicle composite bottom boards, it is characterized in that said plastics or the thick 1-5mm of rubber and plastic panel, the thick 1-5cm of polyurethane base plate.
4,, it is characterized in that said enhancement layer is syntheticfibres, cloth or felt according to claim 1 or 2 described passenger vehicle composite bottom boards.
5,, it is characterized in that said enhancement layer is positioned at the composite panel bottom according to the described passenger vehicle composite bottom board of claim 4.
