Abstract

The present invention discloses a nano-PET / PTT alloy material, which comprises the following components in mass percentage: 25-55% of PET, 20-35% of PTT, 10-15% of nano-particles, 0.1-0.5% of coupling agent, 5-8% of plasticizer, 2-4% of compatilizer, 0.1-0.5% of anti-oxidant, 0.1-1% of lubricant, and 8-12% of glass fibers. The nano-particles are composed of one component selected from nano calcium carbonate, nano silica, nano magnesium hydroxide, nanometer kaolin and nano-montmorillonite. According to the invention, the original advantages of PET and PTT materials are kept, while the alloy material is excellent in mechanical performance, heat resistance and processability at the same time. Meanwhile, the alloy material is warpage-free, good in appearance, low in cost and wide in adaptability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a nano-PET / PTT alloy material. Background technique [0002] Polyethylene terephthalate (PET) / polytrimethylene terephthalate (PTT) belongs to a new type of polymer plastic alloy material, which has excellent molding processing, impact resistance, high temperature heat aging resistance, and Chemicals and other properties, so it will have broad application prospects in the fields of automobiles, electronic appliances, home appliances, and fibers. However, the unstable mechanical properties of PET / PTT, poor high heat resistance, and rough surface of the product will greatly limit its application effect. In order to improve the performance of PET / PTT, it is often necessary to add a third component to PET / PTT for modification, so as to obtain a blended composite system with considerable practical value. Nanoparticles can not only significantly improve the mechanical proper...
