Abstract

The invention discloses a carbon nanofiber reinforcing PTT / poly(ether-ester) composite material. The composite material comprises the following ingredients, by weight, 55%-85% of PTT, 5%-25% of TPEE, 2%-4% of compatilizers, 5%-15% of carbon nanofibers, 0.1%-0.5% of anti-oxidants, 0.1%-1% of lubricants and 3%-8% of flame retardants. The carbon nanofibers are carbon nanofibers with surfaces processed by oxygen (O2) plasma. The beneficial effects are that carbon nanofibers processed by oxygen plasma are employed for filling modification, the intensity, the rigidity and the heat resistance of the material are raised greatly, the electrical performances are excellent, the preparation technology is simple, the processability is good, and popularization and application are convenient.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a nano-carbon fiber reinforced PTT / polyether resin composite material. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, films, engineering plastics, etc., but PTT alone has poor flame retardancy and low strength. No advanced question. Polyether ester (TPEE) is polybutylene terephthalate-polyethylene oxide-polypropylene oxide thermoplastic elastomer, which is composed of dimethyl terephthalate, butylene glycol, polyethylene oxide two A block copolymer obtained by polycondensation of polyalcohols and / or polypropylene oxide diols, which has the elasticity of rubber and the strength of engineering plastics, and will have better processability and longer service life than rubber , Compared with engineering materials, it has t...
