Abstract
A warping-preventing reflecting film comprises a polyester reflecting film body, wherein the surface of the polyester reflecting film body is provided with a wood fiber layer, the ratio of the thickness of the polyester reflecting film body to the thickness of the wood fiber layer is 5 to 1, and the length of wood fibers is 200 microns to 500 microns; after the polyester reflecting film body is formed, the wood fibers are scattered to the surface of the polyester reflecting film body while the polyester reflecting film body is not cooled and are embedded in the surface of the polyester reflecting film body. The wood fibers are curved in a strip shape, are uneven, and are of a multi-hole structure, the cross portions are flat, good tenacity, dispersibility and chemical stability are achieved, and the structure can be enhanced. The wood fibers are added to the surface of the polyester reflecting film body, so that the structure of the polyester reflecting film body is enhanced, and the strip-shaped microstructures of the wood fibers penetrate through the surface of the reflecting film in a cross mode so that warping can be reduced.
Description
Technical field
The present invention relates to a kind of reflectance coating.
Background technology
At present, liquid crystal display is still the one in main flow display now.What in liquid crystal display, provide light source for liquid crystal display is the backlight module in its structure.The device of this backlight module comprises light source, reflectance coating, light guide plate, diffusion barrier, prism etc.The surface of reflectance coating contacts with light source, the light that reflection source produces, the optical property of raising display.
Reflectance coating warpage mainly occurs among the process of two-way stretch, is subject to equipment, technique etc. and is permitted multifactorial impact.Due to the internal stress skewness of film, cause reflectance coating very easily to produce warpage.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing reflectance coating, the invention provides a kind of anti-warpage reflectance coating.
The technical scheme that the present invention solves its technical matters is: a kind of anti-warpage reflectance coating, comprise polyester reflectance coating body, the surface of described polyester reflectance coating body has one deck wood fibre layer, the thickness of polyester reflectance coating body is 5:1 with the ratio of the thickness of wood fibre layer, and the length of wood fibre is 200 ~ 500 μ m;
After polyester reflectance coating basis is body formed, when polyester reflectance coating body is uncolled, wood fibre is sprinkled upon to polyester reflectance coating body surface, wood fibre embeds polyester reflectance coating body surface.
Beneficial effect of the present invention is: wood fibre is band sigmoid, and uneven, has porous structure, and infall is flat, has good toughness, dispersiveness and chemical stability, can strengthen structure.Surface at polyester reflectance coating body increases wood fibre structure, strengthens the structure of reflectance coating itself, and the banded micromechanism of wood fibre is intersected can reach the object that reduces warpage through reflectance coating surface.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, a kind of anti-warpage reflectance coating, comprises polyester reflectance coating body 1, and the surface of described polyester reflectance coating body 1 has one deck wood fibre layer 2, the thickness of polyester reflectance coating body 1 is 5:1 with the ratio of the thickness of wood fibre layer 2, and the length of wood fibre is 200 ~ 500 μ m;
Polyester reflectance coating this body formed rear (generally adopting the moulding of two-way stretch method), when polyester reflectance coating body is uncolled is sprinkled upon wood fibre polyester reflectance coating body surface, and wood fibre embeds polyester reflectance coating body surface.
Wood fibre is band sigmoid, and uneven, has porous structure, and infall is flat, has good toughness, dispersiveness and chemical stability, can strengthen structure.Surface at polyester reflectance coating body increases wood fibre structure, strengthens the structure of reflectance coating itself, and the banded micromechanism of wood fibre is intersected can reach the object that reduces warpage through reflectance coating surface.
