Problems solved by technology

However, when the existing organic-inorganic composite antifungal agents are applied to PET materials, it is often difficult to give full play to their advantages, which may be caused by the characteristics of PET itself, such as the long crystallization cycle, etc.

preparation example Construction

[0036] In some embodiments, the preparation method specifically includes:

[0037] Mix PET matrix resin, antifungal agent, antioxidant and other additives evenly to form a mixture;

[0038] The mixture is heated to a selected temperature for melt extrusion, and after being extruded and pelletized by a screw, the obtained mold-resistant PET masterbatch is injected or blow-molded to obtain the PET mold-resistant material. Wherein, the selected temperature is 260-290°C, preferably 270-280°C.

[0039]The applicant unexpectedly found that when ZIF-8 is compounded with PET matrix resin and additives at an addition amount of 3wt% or less, especially 5wt‰~1wt%, not only can the formed PET anti-mold material have excellent anti-mold properties For example, the anti-mildew grade of Aspergillus niger (A. niger), Penicillium funiculosum (P. funiculosum), etc. is not lower than grade 1, and it also shows good nucleation effect, which can effectively shorten the nucleation cycle of PET, T...

Abstract

The invention discloses a PET (Polyethylene Terephthalate) mildew-proof material as well as a preparation method and application thereof. The PET mildew-proof material comprises PET matrix resin, a mildew-proof agent and an auxiliary agent which can be selectively used or not used, wherein the mildew-proof agent is ZIF-8. The PET mildew-proof material provided by the invention is excellent and stable in mildew-proof performance and mechanical performance, high in environmental weather resistance, easy to prepare, short in forming period and simple to construct, and can fully meet the mildew-proof requirements in the fields of packaging, household appliances, automobiles and the like.

Description

technical field [0001] The application relates to an anti-mildew material, in particular to a PET anti-mildew material and a preparation method and application thereof, such as the application in the preparation of a multi-layer anti-mildew structure, belonging to the field of functional materials. Background technique [0002] Polyethylene terephthalate (PET) has excellent high and low temperature resistance, good barrier properties, high transparency, good gloss, and is in most solvents such as oil, fat, dilute acid, dilute alkali, etc. Many excellent characteristics such as excellent stability make it the most important variety in the current thermoplastic polyester. At present, PET materials are widely used in chemical fiber, packaging industry, electronic appliances, medical and health, construction, automobiles and other fields. Among them, packaging materials are the largest non-fiber application market of polyester, and also the fastest growing field of PET applicati...
