A kind of high diffusing reflection backboard of the high tenacity of co-extrusion, including doubling plate, supporting layer, surface structure, reflecting layer and under
Surface texture, the doubling plate upper end are provided with supporting layer, are bonded with surface structure, the supporting layer at the top of the supporting layer
Bottom is provided with reflecting layer, and the reflecting layer bottom is bonded with lower surface configuration.
Further, the double-deck plate thickness is between 1mm-7mm, and doubling plate is added with colorant, the bilayer
Plate is realized by way of co-extrusion.
Further, the reflector thickness is between 0.1mm-2mm, and the supporting layer thickness is between 0.2mm-5mm.
Further, the supporting layer is added with modifying plastics substance, comprising: fire retardant, impact resistance modification agent, toughening
Agent.

Further, material used in the doubling plate be can thermoplastic material (PC, ABS, ASA, HIPS).
Further, the supporting layer is identical as reflecting layer substrate, or for the good substance of two kinds of compatibilities such as (PC and
ABS).
Compared with prior art, the utility model has the following beneficial effects: the high diffusing reflection backboard of the high tenacity of the co-extrusion,
Doubling plate using can thermoplastic material, in the molten state, if two kinds of materials are identical or compatibility is good, they can be bonded in
Together, two kinds of materials of adhesive surface can be mixed mutually, but will not be mutually mixed inside it, and modifying plastics substance is mostly coloured, no
Transparent substance can absorb light, not have reflection function, and high diffusing reflection substance is generally white inorganic object, has high reflection
Property, but its addition will not influence the physical property of plastics itself, and doubling plate combines two kinds of functions, while having high-strength
Degree and high reflection, improve the toughness and intensity of backboard, improve the intensity of reflector plate, improve the reflectivity of reflector plate, improve plane
The insulating properties and shock resistance of lamp reduce assembly process, reduce production cost, avoid because caused by the deformation of reflector plate
It is bad.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: doubling plate 1, supporting layer 2, surface structure 3, reflecting layer 4, lower surface configuration 5.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, a kind of high diffusing reflection backboard of the high tenacity of co-extrusion, including doubling plate 1, supporting layer 2, surface structure
3, reflecting layer 4 and lower surface configuration 5,1 upper end of doubling plate are provided with supporting layer 2, surface structure 3 are bonded at the top of supporting layer 2,
2 bottom of supporting layer is provided with reflecting layer 4, and 4 bottom of reflecting layer is bonded with lower surface configuration 5.
Wherein, 1 thickness of doubling plate is between 1mm-7mm, and doubling plate 1 is added with colorant, the doubling plate 1
It is realized by way of co-extrusion, thickness is moderate, and mixes conveniently.
Wherein, for 4 thickness of reflecting layer between 0.1mm-2mm, 2 thickness of supporting layer is thick between 0.2mm-5mm
It spends moderate, facilitates installation.
Wherein, the supporting layer 2 is added with modifying plastics substance, comprising: fire retardant, impact resistance modification agent, toughener, meeting
