Abstract

The invention discloses a toughening reinforcing anti-aging PET/PTT alloy, which comprises the following components by mass: 25%-54% of PET, 15%-25% of PTT, 8%-12% of glass fiber, 8%-12% of a composite filler, 6%-9% of MBS, 2%-4% of GMA-St-AN, 1%-3% of an aging resistant agent, 0.1%-0.5% of an antioxidant 1010, 0.5%-1% of TAF, and 5%-10% of a flame retardant. The flame retardant is a compound of PSPPP and antimony trioxide in a mass ratio of 2-4:1. The toughening reinforcing anti-aging PET/PTT alloy provided by the invention has the respective advantages of PET and PTT, also has good toughening, reinforcing, anti-aging, and halogen-free flame retardant effects, enhances the application field of PET/PTT, and has very good practical value and promotion prospects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a toughened, reinforced and anti-aging PET / PTT alloy. Background technique [0002] Polyethylene terephthalate (PET) / polytrimethylene terephthalate (PTT) is a new type of polymer plastic alloy material, which has excellent physical and chemical properties and processing properties, so it is widely used in automobiles, electronics and electrical , home appliances, fiber and other fields will have broad application prospects. However, the low toughness, unstable mechanical properties and poor aging resistance of PET / PTT will greatly limit its application effect and application field. Contents of the invention [0003] The purpose of the present invention is to provide a toughened, reinforced and anti-aging PET / PTT alloy with good comprehensive performance, excellent flame retardancy and wide adaptability. [0004] The technical solution adopted by the present inventio...
