Problems solved by technology

Usually, the adoption of this process will make the product have the following disadvantages: (1) Both sides are PMMA, which cannot be heat-sealed with other PHA card bodies (2) After the surface hardening agent is cross-linked and cured, it will cause the surface of the material to wet Tension decreases, making it difficult to print, and it will also cause the material to become brittle as a whole, which is not conducive to secondary processing such as card punching

Abstract

The invention discloses a scratch-resistant degradable licence card base material and a preparation technology thereof. The base material comprises an upper layer and a lower layer. The upper layer comprises 92.8-97.8wt% of PMMA resin, 2-5wt% of a plasticizer, 0.1-0.7wt% of a lubricant, 0.1-0.5wt% of an anti-oxidant, 0-0.5wt% of an ultraviolet ray absorber and 0-0.5wt% of an antistatic agent. The lower layer comprises 90.1-94.4wt% of PHA resin, 5-8wt% of a plasticizer, 0.4-0.8wt% of a lubricant, 0.2-0.6wt% of an anti-oxidant and 0-0.5wt% of an antistatic agent. The base material has good scratch resistance, high light transmittance and good heat dimensional stability and can be used for heat seal card preparation. The preparation technology has simple and easy processes and can be industrialized easily. The base material has excellent industrial application value.

Description

Technical field [0001] The present invention is a thermoplastic polyester technology, which involves a degradable degradable degradable card base material and its preparation process. Background technique [0002] Polycroxyl fatty acid ester (PHA) is a type of armoplastic fatty bioline synthesized as a type of carbon source and energy storage when carbon and nitrogen nutritional imbalance.PHA's mechanical properties are similar to that of some thermoplastic materials such as polyethylene and polypropylene. PHA is used to make cards, which can effectively solve environmental problems that are difficult to recycle cards.The existing PHA membrane and chip can meet the basic requirements of the card card, but due to the poor scratch resistance of PHA film (pencil hardness: 2B), due to repeated scratches during the use of the card, the surface of the certificate card is caused by the surface of the card.Blur, affecting the use of the card card, generally requires that the surface penc...
