Abstract

The present invention discloses an enhanced PET / PTT / nano bamboo carbon-based composite material, which comprises the following components in mass percentage: 30% to 56% of PET, 20% to 30% of PTT, 5% to 10% of nano-bamboo carbon, 2% to 4% of compatilizer, 8% to 12% of glass fibers, 5% to 8% of POE-g-GMA, 1% to 3% of nano-silica, 0.5% to 2% of light stabilizer, 0.1% to 0.5% of composite antioxidant, and 0.1% to 1% of TAF. According to the invention, the original advantages of PET and PTT are integrated, and the sterilization and anti-ultraviolet performance of the enhanced PET / PTT / nano bamboo carbon-based composite material is greatly improved by means of the nano-bamboo carbon as fillings. Meanwhile, the enhanced PET / PTT / nano bamboo carbon-based composite material is good in mechanical performance, high in strength, good in chemical resistance, low in cost, small in warpage, good in appearance and easy to generalize.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a reinforced PET / PTT / nanometer bamboo carbon composite material. Background technique [0002] Polyethylene terephthalate (PET) is a crystalline polymer with a high melting temperature and glass transition temperature. It maintains excellent physical and mechanical properties within a certain temperature range, and its fatigue resistance , Friction resistance, aging resistance, electrical insulation characteristics are very outstanding, stable to most organic solvents and acids, production energy consumption is low, so it is widely used in synthetic fibers, films, engineering plastics and other fields; but because of PET The strong rigidity makes the material toughness poor, the crystallization speed is slow, the high temperature of the molding die and the long molding cycle are shortcomings, which greatly limit its application range. [0003] Polytrimethylene terephthalate (...
