Abstract

The invention relates to a high-performance thermoplastic alloy plate and a preparation method thereof. The high-performance thermoplastic alloy plate comprises the following components in parts by weight: 30-50 parts of thermoplastic polyester resin, 15-20 parts of acrylic ester, 0.5-2 parts of an impact modifier and 0.1-0.5 part of an anti-aging agent. For the thermoplastic polyester resin, the viscosity of the thermoplastic polyester resin is improved by using the acrylate; in addition, the impact modifier which has a good toughening effect on the thermoplastic polyester resin is added; and the impact modifier and the acrylate have a good synergistic toughening effect, so high impact strength is obtained.

Description

technical field [0001] The invention relates to the technical field, in particular to a high-performance thermoplastic alloy plate and a preparation method thereof. Background technique [0002] Thermoplastic polyester alloys are high-performance engineering plastics, especially when they are reinforced with glass fibers, they have excellent mechanical and electrical properties, so they are widely used in various industries. However, thermoplastic polyester alloys also have some very obvious deficiencies, which are mainly reflected in relatively large shrinkage, high density and low impact strength during forming. The thermoplastic polyester alloy prepared by alloying method, on the one hand, can use the high solvent resistance of polyester so that the alloy can be directly used to make the product parts that need to be coated on the surface. On the other hand, compared with thermoplastic polyester resin , the prepared alloy not only has low density and high impact strength...
