Said overcoat 1 is processed for the macromolecular material that is compounded in outside the cushion coat and have an ageing resistace.Overcoat 1 main effect is the protection to inner layer material; The preferential solution is that whole guardrail board outermost material is prone to aging, wear problems; Therefore need select pliable and tough, anti abrasive base resin material for use; In base resin material, add anti-aging materials such as antioxidant, light stabilizer, can also add antiseptic, its hygiene of Nano self-cleaning material maintenance, can also add the auxiliary material that improves rigidity and abrasion resistance.Also comprise eye-catching color matching attractive in appearance and embedded photoluminescent material in the material of overcoat 1.When needing, overcoat 1 also can comprise the material of reinforcing material surface impressionability.The thickness of overcoat is generally not thick, gets final product at 0.5～1mm.
When the heat-stabilized wood flitch is selected the single layer structure that has only cushion coat for use, be mainly used in the position of not exposing, for example in the multilayer dowel, the dowel that is sealed between outermost layer dowel and the beam slab 100 just can not adopt overcoat, only needs buffering.In addition, can add some anti-oxidant, high-abrasive materials in the cushion coat of individual layer, make itself also to have anti-aging and wear-resisting character.
Like Fig. 8, shown in 9, the thermoplastic composite plate comprises enhancing skeleton 4 and layer of thermoplastic material.Said enhancing skeleton 4 is vertical or/and transversely arranged forming far above at least one section bar of thermoplastic material for hot strength.Said enhancing skeleton 4 perhaps strengthens skeleton 4 and is obliquely installed on the plate face of said beam slab 100 perpendicular to the plate face of beam slab 100, and bottom inclination angle or the overall inclination angle of said enhancing skeleton on beam slab 100 is not less than 70 °.
Because the thermoplastic composite plate will have suitable mechanical strength and rigidity; Strengthen skeleton 4 and in the whole plate body of thermoplastic composite plate, play support, anti-collision effect; Therefore; Strengthen skeleton 4 and select the section bar of modulus of elasticity greater than the modulus of elasticity of layer of thermoplastic material, section bar be meant through rolling, extrude, object that technology such as casting is processed with certain geometrical shape.The hot strength of said enhancing skeleton is 1: 10～1: 150 with the ratio of the hot strength of layer of thermoplastic material, any data in this scope can, just need carry out the selection of thickness and shape to the material of different hot strengths.The preferred hot strength that strengthens skeleton is greater than 120MPa.The utility model preferred tensile strength is much larger than the section bar of layer of thermoplastic material; Section bar can be selected shape, organic reinforcing profile and inorganic reinforcing profile; During use, can use a kind of section bar separately, also can section bar collocation multiple shape is different, that material is different use together.
The said enhancing skeleton 4 of the utility model is tabular, bar shaped, tubulose, linear or pencil; Perhaps said enhancing skeleton 4 is that tabular, strip or linear pressure tabled scarf or cross section cold rolling, that welding is combined into one are tree-like; Or said enhancing skeleton 4 is that a plurality of section bars are arranged side by side or spacing is arranged and the compound back of thermoplastic overall sectional is tree-like structure, and the tree structure that promptly strengthens skeleton 4 is that a plurality of section bars obtain after compound through thermoplastic.Shown in figure 10; The edge of the enhancing skeleton 4 of tree structure all is provided with the edge of a wing 41 of outside turnover; Each end of the enhancing skeleton 4 that two laminations are folded or cold rolling, welding is compound all is extended with the edge of a wing 41 to both sides respectively; The effect on the edge of a wing 41 is to extend in adjacent beam slab 100 or the flange, has strengthened overall structure.The also a plurality of section bars of tree structure shown in Figure 10 are arranged side by side or spacing is arranged, and the enhancing skeleton that obtains after compound through thermoplastic.But a plurality of section bar spacings are arranged in economical with materials under the prerequisite of guaranteed strength, reduce cost and strengthen cushioning effect.
