Abstract

The invention discloses a glass fiber reinforced nylon 6-polyethylene terephthalate alloy material and a preparation method thereof which can be applied in the industries of electric tools, automobiles, electronics and electrics and the like, and belongs to the technical field of macromolecular materials. The alloy material is prepared from the following raw materials in percentage by weight: 44 to 55 percent of nylon 6 resin (PA6), 4 to 12 percent of polyethylene terephthalate (PET), 24.5 to 44.6 percent of glass fiber, 2 to 10 percent of compatibilizer, and 0.1 to 0.5 percent of antioxidant. By adding the homemade compatibilizer in certain ratio in the glass fiber reinforced nylon 6-polyethylene terephthalate and changing the ratio of the PA6, the PET and the compatibilizer, high impact resistance and toughness can be maintained, and dimensional stability and climate resistance can also be kept.

Description

technical field [0001] The invention relates to a glass fiber-reinforced nylon 6-polyethylene terephthalate alloy material and a preparation method thereof, which can be used in electric tools, automobiles, electrical and electronic industries, and belongs to the technical field of polymer materials. Background technique [0002] Nylon 6 is a kind of engineering plastic with a wide range of uses. It is prepared by the polymerization of caprolactam. Its melting point is 215-225°C, and its service temperature range is -40°C-150°C. Due to the influence of temperature and environment, the performance of ordinary nylon 6 will vary. Substantial changes occur, so its application is greatly limited. Therefore, its comprehensive performance can be significantly improved by filling and strengthening modification. [0003] Polyethylene terephthalate (PET) is currently the most important polyester, commonly known as polyester resin. PET mainly has the following characteristics: good r...
