Abstract

The invention discloses a PTT based flame retardant and antistatic masterbatch, which comprises the following components by mass: 15%-40% of PTT resin, 20%-30% of PSPPP, 15%-30% of polydimethylsiloxane, 5%-15% of antimony trioxide, 0.5%-2% of polytetrafluoroethylene, 8%-15% of POE, 5%-10% of an antistatic agent, 0.5%-2% of an antioxidant, and 0.5%-5% of a dispersant. The antistatic agent is one or more of polyethylene oxide, polyether ester amide, polyether ester imide, glycerol monostearate and polyether ester amide compound. When applied to a PTT production process, the PTT based flame retardant and antistatic masterbatch has excellent flame retardant, toughening and antistatic modification effects when the mass fraction is 5%-15%, and has the advantages of good machinability, convenient use, low cost, strong adaptability, simple preparation process, and easy industrial production, popularization and application.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant and antistatic masterbatch based on polypropylene terephthalate. Background technique [0002] Polytrimethylene terephthalate (PTT) is produced by polycondensation of terephthalic acid and 1,3-propanediol. A promising new type of polyester polymer material newly developed after alcohol ester (PBT). Compared with PET and PBT, PTT has many excellent characteristics such as high elasticity, good continuous printing and dyeing characteristics, anti-ultraviolet, anti-internal stress, low static electricity, good biodegradability, and recyclability. In addition, PTT has good processability, low hygroscopicity, high dimensional stability, and small change in physical properties. It has both the high performance of PET and the easy processability of PBT. Therefore, PTT has very broad application prospects in many fields such as carpet industry, clothing mate...
