Thus form multilayer film reflector plate through extruding. Whether the last characteristic detecting this reflector plate to detect device 128,128 ' again meets the requirements.
If this multilayer film reflector plate has specific end use, then such as step S120, can insert in specific device after cutting out and cutting, form protection mirror as being installed in mirror holder.
The above-mentioned common extrusion technique utilizing the common extruding machine of Figure 12 to perform, wherein when the birefringent material layer made in multilayer film reflector plate, material can be carried out single shaft or biaxial stretch-formed by drawing process by multi-layered polyester material film specific in layered film material, the effect that all directions have refringence can be formed between the optical film of polyester material, make this birefringent material layer have the characteristic of X, Y two direction different refractivities in plane, or have the characteristic of different refractivity with vertical Z direction. Utilize drawing process that the material forming birefringent material layer is done the stretching of twin shaft, wherein can utilize successively biaxial stretch-formed, longitudinally (MD) stretching several times, laterally (TD) stretching several times, can also utilize simultaneously biaxial stretch-formed, longitudinally with cross directional stretch several times, and the different retes after stretching have certain refringence.
Multilayer film reflector plate making method embodiment schema as described in Figure 13 again. At the beginning such as step S131 in figure, by the throat-fed layered film material of common extruding machine, the layered film material of this example can comprise the materials such as above-mentioned protective layer, can change according to various actual demand. After through cleaning, dry, heating, mixing, impurity screening, control discharge-amount, extrusion technique (step S133) altogether such as control thickness and size etc., finally extrude formation multilayer film reflector plate.
Step, then such as S135, utilizes laminating type outside in multilayer film reflector plate to form functional membrane, and the binding substances of formation can have waterproof, antireflection, antifog, scratch resistant or structure-reinforced or function of its combination. For another example step S137, fits in the binding substances of multilayer film reflector plate and functional membrane by base material.Base material can produce the effect of antireflection by adding particle, or the mode utilizing pressing mold or roller impression forms surface tissue, makes it to produce scratch resistant, shock resistance, antiultraviolet, the function such as antifog. Afterwards such as step S139, extrudate is used on required object through cutting out to cut.
Then another embodiment schema of the making method of multilayer film reflector plate as depicted in figure 14.
Such as step S141, equally according to required pattern by one or more throat-fed layered film material, afterwards such as step S143, perform extrusion technique altogether, the preliminary pattern of multipolymer of multilayer film reflector plate is formed after extrusion technique altogether, it is with the flow process difference described in Figure 13, after joint function film (step S145), this example utilizes in-mold forming process (InMoldDecoration/Forming, IMD), then need to cut, by cutting out, the size (step S147) obtaining required multilayer film reflector plate before in-molded. Therefore such as step S149, in-molded mode is utilized with other material once in conjunction with base material and the multipolymer formed through extruding altogether.
In above-mentioned in-molded step; by common extrude the multipolymer that formed with will in conjunction with base material, functional membrane, the material such as protective layer be positioned in mould; then companion base material ejection formation is the finished product, is fitted in by the substrate material of ejection formation on the multipolymer of common extrusion technique generation simultaneously.
In sum, this specification sheets proposes a kind of multilayer film reflector plate reflecting pattern, and wherein main body is multi-layer film structure, and has polarization effect, coordinates the use of various functional membrane, makes it to have ultraviolet light, scratch resistant with high reverse--bias effect.
The foregoing is only the better possible embodiments of the present invention, do not limit the patent scope of the present invention with this, therefore every equivalent structure change utilizing specification sheets of the present invention and accompanying drawing content to be formed, all should be included within the scope of the present invention.
