Abstract

The invention discloses a polycarbonate material for a honey bottle. The polycarbonate material is prepared from raw materials in parts by weight as follows: 100 parts of base stocks, 30 to 40 parts of fillers, 0.2 to 0.3 part of antioxidant, 1 to 3 parts of compatilizer and 1 to 2 parts of lubricant, wherein the base stocks are polycarbonate, polyethylene and a thermoplastic polyurethane elastomer; the fillers are kaolin, modified carbon nano tubes and modified titanium dioxide. The invention further discloses a preparation method of the polycarbonate material for the honey bottle. The polycarbonate material has an excellent antibacterial property, and notch sensitivity is reduced.

Description

Technical field [0001] The invention relates to the technical field of plastics, in particular to a polycarbonate material for honey bottles and a preparation method thereof. Background technique [0002] Polycarbonate is colorless and transparent, heat-resistant, impact-resistant, flame-retardant BI grade, has good mechanical properties at ordinary use temperature, dimensional stability, and good heat resistance. It is a very good food packaging material, often made However, polycarbonate is sensitive to notches and has poor UV resistance, preventing its application. As a food packaging material, it has a long contact time with food and is prone to bacteria. Summary of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes a polycarbonate material for honey bottles and a preparation method thereof. The present invention has good antibacterial properties and reduced notch sensitivity. [0004] The present invention prop...
