Example

[0082] Embodiment 1-10, comparative example 1-3:

[0083] The raw materials are shown in Table 1-2. In addition to reinforcing materials such as glass fiber and potassium titanate whiskers, other raw materials were mixed in a high-speed mixer for 5 minutes, and then pelletized using a TEX30α twin-screw extruder (L / D=45.5) manufactured by Nippon Steel Works. Add from the main feeding port of the extruder, glass fiber and potassium titanate whisker are added from the side feeding port of the extruder, the temperature of the extruder is set at 200°C-290°C, the screw speed is 200 rpm , extrude, cool, and pelletize to obtain granular polyester alloy composition; after drying the granular material in an oven at 130° C. for 3 hours, injection molding is made into a standard spline (the size of the spline mold is 10 mm wide × 4 mm thick), press The above-mentioned test method is tested, and the obtained test results are recorded in Tables 3 and 4.

Abstract

The present invention provides a high-toughness polyester alloy composition and a preparation method thereof, wherein the composition mainly comprises the following raw materials by weight: (A) polybutylene terephthalate, (B) polyethylene terephthalate, and (C) an ionomer compound using an ethylene octene copolymer as a matrix. The preparation method comprises: adding (A) polybutylene terephthalate, (B) polyethylene terephthalate, (C) an ionomer compound using an ethylene octene copolymer as a matrix and other additives to a high speed material mixer, adding to a twin-screw extruder after the mixing, and carrying out melt extrusion granulation. According to the present invention, the polyester resin alloy reinforcing material composition has good impact resistance and good fluidity, and the product prepared by using the high-toughness polyester resin alloy reinforcing material composition has characteristics of low warping, high strength and high toughness, and is suitable for vehicles, mobile phones, and notebook computer products.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-toughness polyester resin alloy composition and a preparation method thereof. Background technique [0002] Thermoplastic polyester resins such as polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT) and polyethylene terephthalate (PET) have excellent mechanical and electrical properties , especially PBT and PET have excellent formability, mechanical properties and electrical properties are widely used in electronic and electrical equipment, household equipment, office automation equipment, automobiles and mechanical equipment and other fields. [0003] PET has a high glass transition temperature, slow crystallization speed, long molding cycle, and low fracture impact strength, which limits its application in engineering plastics. The method of copolymerization and blending of PET and other materials can synthesize their respective properties...
