Abstract

The invention discloses a polypropylene material capable of resisting high temperature and oxidation and a preparation method thereof. The material is prepared, by weight, from the following components: (1) 97.5-99.5% of polypropylene (2) 0.5-2.5% of fullerene intercalated zirconium phosphate compound; according to the invention, fullerene zirconium phosphate is used for reaction to prepare the fullerene intercalated zirconium phosphate compound for the first time to improve the high-temperature and oxidation resistance of the polypropylene material; and the obtained polypropylene material hasexcellent oxidation resistance, can resist high temperature above 200 DEG C without thermal oxygen aging. According to the invention, the forming and processing technology is simple and easy to implement, obvious in effect and suitable for practical application.

Description

technical field [0001] The invention relates to processes such as blending of polymer materials, anti-oxidant heat resistance of materials, and the like, in particular to a polypropylene material capable of resisting high temperature oxidation (high temperature oxidation above 200°C) and a preparation method thereof. technical background [0002] Polypropylene is one of the resins with the largest output in the world, and is widely used in many industries such as packaging, textiles, building materials, automobiles, electronic appliances, and office supplies. One of the non-negligible disadvantages of polypropylene is its poor oxygen resistance, which is very prone to aging under the influence of oxygen and temperature. After aging, polypropylene products often cause their own color changes and mechanical properties to decrease, which in turn affects the appearance, performance and life of the products. Moreover, in order to improve production efficiency and reduce viscoela...
