Abstract
The invention discloses a light diffuser board integrated with high transmittance, high haze and high toughness in one body. A fiber-level GPPS such as transparent and blue-background polystyrene is taken as a main material, glass beads are taken as a silicon diffusion agent, and a high haze flexibilizer SCBS is innovatively added. Based on the diffuser board having functions of light collection, light diffusion and light reflection, a product formula is improved and added, auxiliary agents such as a diffusion agent, a light stabilizing agent and a high haze flexibilizer are added to a raw material, and thereby functions of light refraction, light reflection and light diffusion are realized in products, not only can quite high light diffusion and emergent light uniformity be realized, but also a utilization rate of the power source is high, anti-folding performance and shielding performance are good, a penetration rate of products can reach 93%+/-5%, and the haze can reach 99%+/-1%.
Description
Technical field
The invention belongs to field of photovoltaic materials, be specifically related to a kind of light harvesting high permeability, high mist degree and high tenacity in the light diffusing sheet of one.
Background technology
Diffuser plate has been widely used in the systems such as liquid crystal display, LED illumination and imaging at present, makes the abundant scattering of incident light, realizes softer, uniform radiation response.Diffuser plate is when producing solid slab, adds that diffusant forms in raw material.Diffusant can be evenly distributed in sheet material, makes light when the sheet material, while encountering diffusant particle, reflect, reflection, the effect of scattering, thereby make light can be uniformly through sheet material but can not expose light source, reach the variation from pointolite to area source.Be applicable to straight-down negative LED backlight of television module, mobile phone module, LED illumination, there is high briliancy, high diffusibility, improve the luminous diffusion effect being evenly distributed of backlight.
Research for diffuser plate is more, CN200680055637 and patent CN101684922A disclose a kind of manufacture method of light diffusing sheet, patent discloses inorganic diffusant, as calcium carbonate, silicon dioxide, siloxane, zinc sulphide, titanium dioxide, titanium phosphate, magnesium titanate, mica, glass filler, barium sulphate, clay, talcum; Silicone rubber kinds elastic body, methyl polysilicone Wan oxane etc. with organism as acrylic acid, styrene, polyester-type, polyolefin-type, urea alkane type, nylon type, methacrylic acid styrene type, fluorine type, slab alkene type etc. falls as the scheme of diffusant.The inorganic particulate of mentioning in patent is as silicon dioxide, it has been a kind of conventional light diffusing agent on market, although these inorganic particulates join the mist degree that can increase resin in resin, but can significantly reduce transmittance, usually, add the transmittance (1.2mm polycarbonate) of the diffuser plate of this inorganic particulate can not be greater than 70%.Loss when the organic light diffusing agent of mentioning in patent can reduce light transmission diffuser plate, but can not thoroughly avoid the loss of light, in the situation that mist degree is suitable, the transmittance that adds the light diffusing sheet of organic light diffusing agent acquisition is generally not more than 80% (1.2mm polycarbonate).
Along with TV market people's demand, the thickness of present backlight module is more and more thinner, and light source utilization factor requires more and more higher, also more and more higher to the requirement of diffuser plate mist degree, toughness when not affecting briliancy; The diffuser plate of producing on domestic and international market at present more and more cannot meet terminal market demand.
Therefore, further increase light source transmitance, reduce light source loss, improve the outgoing light homogeneity of backlight module, improve the brightness of whole module, on light diffusing sheet, realize and integrate the research emphasis that the functions such as high briliancy, high mist degree and high tenacity become current diffuser plate industry.
