The invention provides a PVC optical film, including optical film thickness is 0.5 ~ 5mm body, light body has a positive film plane and the back plane is plane by embossing roller is provided with a grating grating pressure embossing; optical film body consists of the following parts by weight of raw materials: PVC resin 60 ~ 90, DOP or DOTP28 - 33, stabilizer 1.20 - 1.80, 0.01 - 0.03, soybean oil proof agent 0.02 ~ 0.05 copies, 2 - 3, methyl modified agent 0.01 - 0.03, 0.01 - 0.03, processing aids anti UV agent 0.02 ~ 0.05, 0.007 ~ 0.012 pigment. PVC optical film of the invention is soft, can be rolled up and packing, convenient transportation; making three-dimensional painting, do not need transparent medium between the PVC film and the stereo pattern, compared to the existing technology of grating film material to produce three-dimensional paintings, reducing a procedure, thereby lowering the defective rate; at the same time to the back plane in the light of Film Ontology pattern direct printing is complete three-dimensional painting production, greatly simplifies the production process of three-dimensional painting, and the production of three-dimensional picture of the stereoscopic.

一种PVC光膜
本专利技术涉及柱镜光栅成像
,特别是涉及一种PVC光膜。
技术介绍
随着柱镜光栅立体成像技术的日趋成熟,自由立体画以观看自由,图像逼真,立体感强等优势而逐渐被广泛用于广告宣传、产品包装、图书插页和艺术立体画等。目前,自由立体图通常采用光栅板和光栅膜而制成,光栅板和光栅膜绝大部分基材采用PET板材或BOPP薄膜,并在PET板材或BOPP薄膜的正平面上借助光栅压纹辊筒压设有呈柱状或圆点状的光栅压纹。光栅板的特点是:1、厚度为2mm~8mm之间;2、立体感强:光栅成像的特点决定同样景深的立体画,板材光栅可产生更大的立体感,更加逼真,更加震撼;3、视距远:2至10m左右,解决了片材立体画只能拿在手中把玩的尴尬,板材光栅最大可做到幅宽1.2m,丰富了立体图案的应用,更有利用大幅面立体画,立体广告,个性立体的制作;4、光栅条纹数目小,极大有利于立体画的打印制作,满足了量少质高的个性化立体画制作,比如立体广告,大幅面立体画,立体照片等;5、经久耐用:材料厚不易损坏,表面不弯曲,不变形,寿命长,容易打理清洁。其缺点是:不能量产,成本高,制作工艺影响成品率,不能折叠或卷起,运输受到尺寸的限制,运输很不方便,运费高。光栅膜的特点:1、厚度为12~20um;2、透明度高、光亮度好、无毒无味、耐水、耐热、价格价廉、质地柔软。其缺点是:制作立体画时,由于立体光栅膜与立体图像中间要有透明介质,需要先将光栅膜和PET透明度非常高双面胶粘贴在透明介质上,然后再进行裱画,比柱镜立体光栅板和柱镜立体光栅片在制作立体画时多一道工序,影响了光栅弧度的聚焦的准确性,从而增加了 ...
