Abstract

The invention discloses a scratching-resistant low-cost environmental-friendly type polypropylene material and a preparation method thereof. The scratching-resistant low-cost environmental-friendly type 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, 1.5-2parts of glycine, 1.8-2.3 parts of dioctyldilauryltin and 0.05-1 part of an antioxidant. The invention further provides a preparation method of the scratching-resistant low-cost environmental-friendlytype polypropylene material. The preparation method comprises the following steps: uniformly mixing the weighed raw materials in a high-speed mixing machine at a rotation speed of 900-1000rpm, feeding into a double-screw extruder, and performing extrusion, drawing, cooling and pelletizing, thereby obtaining the environmental-friendly polypropylene material.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a scratch-resistant, low-cost and 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 a...
