Abstract

The invention discloses a polypropylene material in a low formaldehyde emission concentration, and relates to the technical field of new materials. The polypropylene material is prepared from 8-15% ofN-doped modified zeolite powder by mass. The prepared polypropylene material has the good mechanical property, and is capable of greatly reducing the formaldehyde emission concentration of the polypropylene material, effectively meeting the environmental requirements, and reducing the disadvantages of formaldehyde to a human body and a natural environment.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a polypropylene material with low formaldehyde emission concentration. Background technique [0002] Polypropylene is one of the most widely used plastics in the world. Because polypropylene itself is non-toxic and safe, it is widely used in indoor and car environments, and is the most used plastic in automotive interiors. Even the field of lunch boxes has developed rapidly. In 2015, the apparent consumption of polypropylene materials for fast food boxes reached 150,000 tons. [0003] However, in the production process of polypropylene products, a large amount of formaldehyde and acetaldehyde will be produced due to thermal oxygen degradation or peroxide oxidation, which will be gradually released into the environment during use, polluting the ambient air and endangering human health. In recent years, due to the improvement of people's awareness of environment...
