PVC (Polyvinyl Chloride) optical film

Abstract

The invention provides a PVC (Polyvinyl Chloride) optical film. The PVC optical film comprises an optical film body with the thickness of 0.5mm to 5mm, wherein the optical film body has a front panel and a rear panel; the front panel is provided with optical grating embossed lines through an optical grating line embossing roller in a pressing manner; the optical film body is prepared from the following raw materials in parts by weight: 60 to 90 parts of PVC resin, 28 to 33 parts of DOP (Dioctyl Phthalate) or DOTP (Dioctyl Terephthalate), 1.20 to 1.80 parts of a stabilizer, 0.01 to 0.03 part of soybean oil, 0.02 to 0.05 part of a cold-proof agent, 2.0 to 3.0 parts of methyl ester, 0.01 to 0.03 part of a modifier, 0.01 to 0.03 part of a processing auxiliary agent, 0.02 to 0.05 part of an anti-UV (Ultraviolet) auxiliary agent and 0.007 to 0.012 part of a pigment. The PVC optical film provided by the invention is a soft film, can be reeled and packaged and is convenient to transport; when a stereograph is drawn, a transparent medium is not needed between the PVC optical film and a stereoscopic pattern; compared with a process of producing the stereograph by an optical grating film material in the prior art, one procedure is reduced so that the defective rate is reduced; meanwhile, the stereograph can be produced by directly printing the pattern on the rear panel of the optical film body, so that a production process of the stereograph is extremely simplified and the produced stereograph has a strong stereoscopic impression.

Description

technical field [0001] The invention relates to the technical field of lenticular grating imaging, in particular to a PVC optical film. Background technique [0002] With the maturity of lenticular stereoscopic imaging technology, autostereoscopic pictures are gradually widely used in advertising, product packaging, book inserts and artistic three-dimensional pictures due to their advantages of freedom of viewing, vivid images and strong three-dimensional sense. [0003] At present, free stereograms are usually made of lenticular plates and lenticular films. Most of the base materials of lenticular plates and lenticular films are made of PET sheets or BOPP films, and are embossed on the front plane of PET sheets or BOPP films by means of grating embossing rollers. Features lenticular embossing in the form of columns or dots. The characteristics of the grating plate are: 1. The thickness is between 2mm and 8mm; 2. Strong three-dimensional effect: the characteristics of the g...

Problems solved by technology

Its disadvantages are: mass production is not possible, the cost is high, the production process affects the yield rate, it cannot be folded or rolled up, the transportation is limited by the size, the transportation is very inconvenient, and the freight is high

Its disadvantages are: when making three-dimensional pictures, since there must be a transparent medium between the three-dimensional lenticular film and the three-dimensional image, it is necessary to paste the lenticular film and PET double-sided tape with very high transparency on the transparent medium first, and then mount the picture, compared with the column. Mirror lenticular plate and lenticular lenticular sheet have one more process when making three-dimensional pictures, which affects the accuracy of the focusing of the radian of the grating, thereby increasing the rate of defective products
