Problems solved by technology

[0004] For example, in Chinese patent CN101760093A, titanate coupling agent is used to process nano zinc oxide, and Chinese patent CN107674314A uses silane coupling agent to process nano zinc oxide, but these coupling agents themselves have certain peculiar smell and are not suitable for automotive interior materials.
Chinese patent CN105566750A discloses a preparation method of low-odor masterbatch, but the low-odor masterbatch cannot achieve antibacterial effect

Abstract

The invention discloses an antibacterial low-odor master batch as well as a preparation method and application thereof. The preparation method comprises the following steps: by taking random PP resin as a matrix, adding santalol and nano-zinc oxide in a certain ratio to prepare master batches; the santalol is used as a dispersing agent of the nano-zinc oxide, so that the nano-zinc oxide cannot be agglomerated, and the dispersing effect is good. In addition, the santalol and the nano zinc oxide can play a role in synergistically resisting bacteria and reducing material odor, so that the master batch is low in preparation temperature, the raw materials are convenient and easy to obtain, and the production process is simple and suitable for large-scale production. The prepared master batch can be further used for preparing antibacterial and low-odor plastic, such as a polypropylene material, so that the polypropylene material has antibacterial and low-odor characteristics; in addition, the synergistic effect of santalol and nano-zinc oxide also improves the impact strength of the material, so that the material is endowed with better application performance. The polypropylene material can be widely applied to household appliances or automobile products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial and low-odor polypropylene composition and its preparation method and application. Background technique [0002] Polypropylene (PP), as a cost-effective general-purpose plastic, is easy to form and process, and is widely used in home appliances and automotive products. Injection-molded polypropylene parts tend to breed bacteria during long-term use, which is not good for the health of users. In addition, the level of odor of polypropylene material products directly affects the comfort and personal health of consumers. Therefore, it is necessary to carry out antibacterial, low-odor formula and process design for polypropylene materials, so that the performance of the materials can meet the needs of passengers. [0003] Nano-zinc oxide is a relatively common antibacterial material. However, nano-zinc oxide is a polar inorganic material with poor compat...
