Preparation method of masterbatch with characteristics of good compatibility, safety, high efficiency, fragrance, antibacterial property and mildew resistance

Abstract

The invention discloses a preparation method of a masterbatch with characteristics of good compatibility, safety, high efficiency, fragrance, antibacterial property and mildew resistance, and belongsto the technical field of novel functional materials, wherein the raw materials comprise: 0.1-8 wt% of an ester, 0.1-5 wt% of organic zinc, 0.2-5 wt% of fragrant essential oil, 2-10 wt% of a filler, 0.01-1.2 wt% of an auxiliary agent, and 71-98 wt% of a resin carrier. The preparation method comprises: uniformly mixing the fragrant essential oil, the filler and the required auxiliary agent according to a certain ratio, stirring and mixing the obtained mixture, the ester, the organic zinc and the resin carrier at a high speed, and carrying out melt blending, extruding and pelletizing on the mixed material under the action of shear force by a twin-screw granulator to obtain the masterbatch with characteristics of good compatibility, safety, high efficiency, fragrance, antibacterial property and mildew resistance. According to the present invention, the masterbatch can be used in the fields of antibacterial plastic wrap products, hollow flexible packaging containers, children toys, children stationery, children tableware, household appliances, kitchen and bathroom products, water supply pipes, medical equipment, traffic tools, construction industry, handicrafts, gifts, shared productsand the like.

Description

technical field [0001] The invention belongs to the technical field of new functional materials, and in particular relates to a preparation method of a good compatibility, safe, high-efficiency, fragrance, antibacterial and mildew-proof masterbatch. Background technique [0002] Due to their low price, convenient processing and manufacturing, good mechanical properties and durability, plastic materials are widely used. Plastic products are almost ubiquitous in people's lives. However, plastic materials are easy to absorb moisture and have large gaps between macromolecular chains. A good place for fungi, plastic products contaminated by microorganisms will not only produce peculiar smell, threaten human health and reduce the mechanical properties of products during use, such as moldy refrigerators, washing machines, air conditioners, water dispensers, car interiors and man-made fiber products etc., and the pollution of harmful microorganisms can also cause food deterioration....
