Abstract

The invention provides a fluorine-containing polymer superfine wax and modified polypropylene composite material and a preparation method thereof. The fluorine-containing polymer superfine wax and modified polypropylene composite material is prepared from, by weight, 50-90 parts of polypropylene, 5-20 parts of fluorine-containing polymer superfine wax, 2-10 parts of a flow modifier, 2-10 parts of a solubilizer and 2-15 parts of glass fiber. Due to the fact that the fluorine-containing polymer superfine wax is organic polymer which can be easily bonded with a polypropylene interface, the compatibility is good. Meanwhile, due to the fact that the solubilizer is added, the good compatibility of the fluorine-containing polymer superfine wax with the glass fiber, the polypropylene and the glass fiber can be remarkably improved, the obtained composite material has the high mechanical performance, also has the high friction resistance and can be widely applied to manufacturing products with the requirement for high strength and high corrosion resistance.

Description

Technical field [0001] The invention belongs to the field of functional polymer materials, and relates to a fluorine-containing polymer micropowder wax modified polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a non-toxic, odorless, odorless, and excellent thermoplastic. It is one of the five general plastics and has good molding and processing properties, dielectric properties and high-frequency insulation. It is widely used in many fields such as automobile industry, household appliances, electronics, packaging, building materials and furniture. In the past 10 years, my country’s polypropylene consumption has grown at an average annual rate of 10%, which has greatly exceeded the world’s average growth level and is my country’s second largest consumption of synthetic resin. However, due to its low mechanical strength, large molding shrinkage, low impact toughness, poor creep resistance, non-wear resistance, a...
