Anti-fake holographic high molecular material

Abstract

The invention discloses an anti-fake holographic high molecular material which comprises the following components in parts by weight: 55-60 parts of epoxy resin modified polyureathane, 3-6 parts of methylcellulose, 1-3 parts of stannous capric acid, 8-9 parts of polytetramethylene glycol, 11-15 parts of methacrylic acid isopropyl ester, 8-9 parts of methacrylic acid glycerol trilaurate, 9-15 parts of modified polypropylene, 5-9 parts of nano calcium sulfate, 14-16 parts of polyamide resin, 3-7 parts of acrylic resin, 3-4 parts of dicyclohexyl peroxydicarbonate, and 1-2 parts of p-tert-butylcatechol. The raw materials are easily available, the raw materials and the product have excellent stability, and the anti-fake holographic high molecular material is convenient to prepare and is convenient for realization of industrial popularization.

Description

technical field [0001] The invention relates to a polymer material for laser holography. Background technique [0002] Functional anti-counterfeiting coating products, including aluminized anti-counterfeiting holographic film, transparent anti-counterfeiting holographic film, anti-counterfeiting holographic hot stamping stuffing, etc. They are made of polyester polymer plastic film, which is thermoplastic, and can transform holographic The interference fringes of the image recorded on the embossed plate are transferred on its surface. These fine embossed fringes record the light wave intensity and phase information of the object to be photographed. This embossed hologram needs to be observed and reproduced by sunlight. Since each wavelength of light in white light will be diffracted by interference fringes, and the diffraction angles are different, there will be images of different colors when viewed from different angles. These products are currently widely used for anti-c...

Problems solved by technology

At present, the raw materials used to prepare holographic film products have difficult sources and high prices, which cannot meet the increasing demand for anti-counterfeiting products, which greatly restricts the development of the anti-counterfeiting industry.
