Abstract

The invention discloses an environment-friendly polypropylene material and a preparation method thereof. The environment-friendly polypropylene material is prepared from the following components in parts by weight: 88-92 parts of polypropylene, 5-10 parts of pentaerythritol stearate, 15-20 parts of an inorganic filler, 1.5-2 parts of polylysine, 1.8-2.3 parts of dioctyldilauryltin and 0.05-1 part of an antioxidant. The invention further provides a preparation method of the environment-friendly polypropylene material. The preparation method comprises the following steps: uniformly mixing the above weighed raw materials in a high-speed mixing machine at the rotation speed of 900-1000rpm, feeding into a double-screw extruder, extruding, drawing strips, cooling and chopping, thereby obtaining the environment-friendly polypropylene material.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to an environment-friendly polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a non-toxic, odorless, tasteless milky white high crystallization polymer. It is cheap, good formability and easy to process. It is widely used in chemical industry, chemical fiber, packaging, home appliances and other industries. [0003] During the modification process of polypropylene, due to the high melting temperature, it is easy to produce small molecule compounds with pungent odor due to degradation or decomposition, such as ketones and aldehyde compounds, etc. These compounds remain in the modified material, and the product It will be released slowly during use. Therefore, it is necessary to add some modification aids in the modification process of polypropylene, such as antioxidants, light stabilizers, coupling agents, and compatibilizers. ...
