Abstract

The invention discloses a low-filling high-performance nanomontmorillonite-reinforced polypropylene composite material and a preparation method thereof. The low-filling high-performance nanomontmorillonite-reinforced polypropylene composite material comprises the following components in parts by weight: 80-90 parts of polypropylene, 5-8 parts of modifying montmorillonite, 4-10 parts of a compatilizer, 0.2-0.5 part of an antioxidant, 0.3-0.6 part of a lubricating agent and 0-3 parts of other auxiliaries. According to the low-filling high-performance nanomontmorillonite-reinforced polypropylene composite material prepared by the preparation method provided by the invention, by a melting intercalation method, a polymer is inserted into spaces between montmorillonite layers and thus the montmorillonite is dispersed into the polymer in a layered structure, so that a similar fiber enhancement role can be played; in addition, a grafting reaction can also be performed on double bonds in a modifier and main chains of the polypropylene, the montmorillonite layers are splayed out by heat released during the grafting reaction, and through chemical bonding of grafts and polymer molecule, the montmorillonite layers are forcibly dispersed uniformly in the polymer matrix so as to form an intercalated nanocomposite material, so that the low-filling high-performance nanomontmorillonite-reinforced polypropylene composite material has excellent mechanical properties, and thus the application range is widened.

Description

[0001] Technical field: [0002] The invention relates to the technical field of polymer composite materials, in particular to a low-filling high-performance nano-montmorillonite reinforced polypropylene composite material and a preparation method thereof. [0003] Background technique: [0004] Improving the strength and low-temperature toughness of polypropylene by compounding with inorganic fillers is a common method for high-performance polypropylene. Generally speaking, nanocomposite materials refer to materials with at least one phase in the material microstructure with a one-dimensional scale reaching nanoscale (1nm-100nm). Due to the small size of nanoparticles and large specific surface area, the number of surface atoms, surface energy and surface The tension increases sharply with the decrease of the particle size, showing the characteristics of small size effect, surface interface effect, quantum size effect and macroscopic quantum tunnel effect, etc., in optical pro...
