Problems solved by technology

The biggest feature of this functional film is that it can greatly inhibit the transmission of ultraviolet rays (99.6%) and infrared rays (80%), so it can prevent skin diseases such as age spots usually caused by ultraviolet radiation, and has the effect of protecting the skin; it is suitable for indoor soft decoration Materials such as tatami mats, curtains, carpets, etc. have the effect of preventing discoloration. The current problem is that the production process is complicated and the price is high, which needs to be improved. At the same time, the polyethylene functional film of the invention does not have the function of filtering blue light.
[0006] In summary, the transparent plasticized PVC functional films currently in use only have a single function of effectively shielding ultraviolet rays and infrared rays or dual functions and functions of shielding ultraviolet rays / infrared rays.

Abstract

The invention discloses a transparent plasticized PVC (Polyvinyl Chloride) functional film which has the characteristic of selective transmittance and absorption of solar spectrums and has the function of effectively shielding ultraviolet light, infrared light and high-energy visible light, namely, blue light and the like. Meanwhile, the invention further provides a preparation method for the transparent plasticized PVC functional film; the preparation method is convenient in operation and stable in product performance. The transparent plasticized PVC functional film is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 60-70 parts of plasticizer, 1.2-1.8 parts of thermal stabilizer, 0.4-0.6 part of ultraviolet absorber, 1.2-6.0 parts of pigment master batch, 0.2-20 parts of surface modified metallic oxide and 0.5-0.8 part of lubricating agent.

Description

technical field [0001] The invention relates to a PVC film and a preparation method thereof, in particular to a transparent plasticized PVC functional film and a preparation method thereof. Background technique [0002] Among the five general-purpose plastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), PE and PP resins Due to the symmetry and regularity of its structure, it is a typical crystalline polymer, and its transparency is relatively poor, so it is not suitable for the preparation of films with high transparency requirements. Although PVC, PS and ABS are all typical non-crystalline resins, since most of the production methods of industrial ABS resins adopt emulsion polymerization, it is not suitable for preparing transparent films; although PS has good transparency, the side group benzene ring in its structure is due to The large steric hindrance effect leads to poor chai...
