Abstract

Belonging to the technical field of high polymer materials, the invention discloses a two-way continuous fiber reinforced polypropylene antibacterial composite material and a preparation method thereof. The two-way continuous fiber reinforced polypropylene antibacterial composite material is prepared from the following components by weight: 30-50 parts of polypropylene resin, 50-70 parts of continuous fiber, 0.5-1.5 parts of an antibacterial agent, 0.5 part of an antioxidant 1010, 1.5 parts of an antioxidant 168, and 4 parts of a compatilizer. The antibacterial composite material provided by the invention is an environment-friendly material, not only has very high mechanical properties but also has antibacterial effect. In addition, the two-way continuous fiber reinforced polypropylene antibacterial composite material provided by the invention also has a relatively low price.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a bidirectional continuous fiber reinforced polypropylene antibacterial composite material and a preparation method thereof. Background technique [0002] Continuous fiber reinforced polypropylene resin is composed of fiber and resin. Polypropylene resin (PP) has excellent physical and mechanical properties, chemical resistance and repeatable processing performance. It is widely used in household daily necessities, electronic appliances, auto parts and The field of industrial materials has been widely used. However, when making some engineering parts and some polymer materials that require high performance, its performance cannot meet the requirements, so its application range is limited to a certain extent; while fibers have high tensile strength, but are easily damaged and Not easy to form and process. The combination of fiber and resin complements the defects of the ...
