Abstract

The invention discloses a PET / PTT material reinforced by glass fiber and resisting bacterial with nanometer bamboo charcoal. The material comprises the following components by weight: 33% to 57% of PET, 20% to 30% of PTT, 2% to 4% of a compatibilizing agent, 8% to 12% of glass fiber, 6% to 9% of a toughening agent, 4% to 8% of nanometer modified bamboo charcoal, 0.5% to 2% of a light stabilizer, 0.5% to 1% of a nucleating agent, 0.5% to 1% of an anti-glassfiber-exposure agent, 0.1% to 0.5% of an antioxidant 1010 and 0.1% to 0.5% of an antioxidant 168. The invention has the following beneficial effects: the PET / PTT material reinforced by the glass fiber and resisting the bacterial with the nanometer bamboo charcoal integrates respective advantages of PET and PTT and has exellent application effects of tensile strength, impact-resistant strength, bending strength, heat resistance and aging resistance; meanwhile, by using the nanometer bamboo charcoal as an antibacterial functional filler, the material also has good functions of antibacteria, ultraviolet prevention, deodorization, odor absorption and antistatic property, so the application fields of the PET / PTT are greatly improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PET / PTT material reinforced with glass fiber and nano-bamboo carbon antibacterial. Background technique [0002] Polyethylene terephthalate (PET) / polytrimethylene terephthalate (PTT) is a new type of polymer plastic alloy material, which has excellent molding processing, impact resistance, and chemical resistance. Therefore, it will have broad application prospects in the fields of automobiles, electronic appliances, home appliances, and fibers. However, PET / PTT has unstable mechanical properties, poor high heat resistance, rough product surface, etc., which will greatly limit its application effect and application field. In order to improve the performance of PET / PTT, it is often necessary to add a third component to PET / PTT to obtain a practical alloy system. Contents of the invention [0003] The object of the present invention is to provide a PET / PTT material ...
