Abstract

The invention discloses a carbon fiber reinforced and nano-bamboo carbon antibacterial PTT functional masterbatch, which comprises the following components by mass: 15%-60% of PTT resin, 5%-25% of modified carbon fiber, 10%-20% of a toughening agent, 15%-30% of nano-modified bamboo carbon, 3%-8% of a thermal stabilizer, 2%-6% of a compatilizer, and 0.5%-5% of a dispersing agent. The modified carbon fiber is chopped polyacrylonitrile carbon fiber with the surface treated by an oxidizing agent polyacrylonitrile solution, and the nano-modified bamboo carbon is nano-bamboo carbon with the surface subjected to nano-titanium dioxide modification treatment and a particle size of 20-80nm. The PTT functional masterbatch provided by the invention has the advantages of environmental protection, no pollution, high dispersion, high strength, high impact resistance and high heat resistance, and has strong adsorption, sterilization, deodorization, purification and other functions, and is convenient to use. When added in production of PTT, the PTT functional masterbatch can have good modification effect and broad application prospects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a carbon fiber reinforced and nano bamboo carbon antibacterial PTT functional masterbatch. Background technique [0002] Polytrimethylene terephthalate (PTT) is a kind of poly(ethylene terephthalate) (PET) and polybutylene terephthalate obtained by polycondensation of terephthalic acid and 1,3-propanediol. Alcohol ester (PBT) is a new type of polyester polymer material, and PTT is more excellent than PET and PBT in terms of mechanical properties, weather resistance, heat aging resistance and hydrolysis resistance. Due to its excellent comprehensive properties, PTT is widely used in the fields of fibers, films, engineering plastics, etc. However, when PTT is used alone, it has the defects of low notched impact strength and high notch sensitivity, which will greatly limit the application of PTT in various fields. Moreover, with the progress of society, people have highe...
