与国内外同类产品或同类技术的比较情况：

反射片用材料的发展历程是金属片、金属箔复合塑料片、塑料片的金属蒸镀品、发泡拉伸聚对苯二 甲酸乙二酯(PET) 片，但这些片材不易形成模塑制品，而且加工繁琐 。聚碳酸酯 (PC) 具有优异的力学性能、电性能、透明性、阻燃性、尺寸稳定性以及耐热性，其光学设计很容易反映在树脂中。目前反射片技术发展的焦点在 PC基材方面。

The development history of materials for reflective sheets is metal sheets, metal foil composite plastic sheets, metal vapor-deposited plastic sheets, and foamed and stretched polyethylene terephthalate (PET) sheets, but these sheets are not easy to mold Products, and the processing is cumbersome. Polycarbonate (PC) has excellent mechanical properties, electrical properties, transparency, flame retardancy, dimensional stability and heat resistance, and its optical design is easily reflected in the resin. The current focus of the development of reflector technology is on PC substrates.

经济评价分析：

反射型PC片项目是因为由于公司销售人员在推广产品时看到其具有较大的市场前景而计划开发的，产品还未开发出来客户已经咨询其相关性能，由于大部分灯具都需要反射纸对背光源的反射，因此在市场上极具竞争力，尤其是侧发光灯具，因此该项目的开发成功就具备了产业化能力。

由于市场需求高，而反射型PC片反射效果较其他材料的反射纸反光系数高，因此极具竞争优势。利润较常规产品高，预计今年开发成功的话年产近200吨，销售额近2000万，因此经济效益也是可观的。

技术及工艺创新要点：

反射片主要应用在以液晶显示装置为代表的投影用屏幕或面状光源的部件、照明器具、照明广告牌等装置领域中 ，其主要作用是将漏出导光板底 部的光线高效率、无损耗地反射回导光板，以增加光 的使用效率，减少用电量，提供液晶显示面所需的光饱和度，因此需要其有较高的反射率

本项目主要是通过添加反射型助剂对聚碳酸酯PC改性处理，再经熔融挤出流延压板使其达到反射光的效果。具体操作是通过选取合适的树脂型钛白粉助剂，包括扩散剂，增白剂，增塑剂，增韧剂等，然后经过造粒-混料-熔融-压延挤出-收卷切片工序成型，其中厚度控制在200μm——500μm之间。

反射型PC片的先进性包括用于吸塑的扩散板需要具有优良的物理机械，尤其是耐冲击性优异，拉伸强度、弯曲强度、压缩强度高，蠕变性小，尺寸稳定;具有良好的耐热性和耐低温性，在较宽的温度范围内具有稳定的力学性能，尺寸稳定性，电性能和阻燃性，可在-60~120℃下长期使用，无明显熔点。核心技术和创新点主要是材料的处理上，即对PC的改性处理研究，需要选取合适的反射型助剂（树脂型包覆的钛白粉）以及配方的调试，使成型的片材不影响反射性能。

The reflective sheet is mainly used in the field of devices such as projection screens or planar light sources represented by liquid crystal display devices, lighting appliances, and illuminated billboards. Its main function is to efficiently and losslessly leak the light the bottom of the light guide plate. Reflect back to the light guide plate to increase the efficiency of light use, reduce power consumption, and provide the light saturation required by the liquid crystal display surface, so it needs to have a higher reflectivity

This project is mainly to modify the polycarbonate PC by adding reflective additives, and then melt and extrude the casting plate to achieve the effect of reflecting light. The specific operation is to appropriate resin-based titanium dioxide additives, including diffusing agents, whiteners, plasticizers, toughening agents, etc., and then pass the granulation-mixing-melting-calendering extrusion-winding and slicing process to shape , The thickness is controlled between 200μm and 500μm.

The advanced nature of the reflective PC sheet includes that the diffuser used for blister needs to have excellent physical machinery, especially excellent impact resistance, high tensile strength, bending strength, high compression strength, low creep, and stable size; It has high heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range. It can be used for a long time at -60~120℃ without obvious melting point. The core technology and innovation are mainly in the treatment of materials, that is, the research on the modification of PC, it is necessary to the appropriate reflective additives (resin-type coated titanium dioxide) and the adjustment of the formula, so that the molded sheet does not affect Reflection performance.
