preparation example Construction

[0040] A preparation method of PET / PBT material, comprising the steps:

[0041] (1) Dry pretreatment of PET and PBT;

[0042] (2) The dried PET, PBT, EMA, E / MAA, and coupling agent are placed in a high-mixer and uniformly mixed to prepare mixture A; Decabromodiphenylethane and antimony trioxide are mixed again, and after mixing, the Nucleating agent, talc, nucleation accelerator, transesterification inhibitor, lubricant, antioxidant A, auxiliary antioxidant B, light stabilizer, polytetrafluoroethylene, and ultraviolet absorber are uniformly mixed together to prepare mixture B;

[0043] (3) Put the mixed mixture B into the mixed mixture A for uniform mixing again, and then add it to the twin-screw extruder after mixing evenly; the glass fiber is added to the twin-screw extruder by side feeding, Pelletized PET / PBT material.

[0044] The condition of drying pretreatment in step (1) is drying at 145-155° C. for 4-6 hours.

[0045] The temperature of each temperature zone of the...

Embodiment 1

[0050] A high-performance PET / PBT material for an air-conditioning compressor junction box, comprising in parts by weight: 46 parts of PET, 5 parts of PBT, 30 parts of glass fiber, 5 parts of EMA, 8 parts of decabromodiphenyl ethane, and 2 trioxide 5 parts of antimony, 0.1 part of PTFE, 5 parts of E / MAA, 0.1 part of HK-185P nucleating agent, 0.5 part of talc, 0.5 part of nucleation accelerator, 0.5 part of transesterification inhibitor, 0.2 part of light stabilizer, UV light 0.2 part of absorbent, 0.2 part of lubricant, 0.2 part of main antioxidant A, 0.2 part of auxiliary antioxidant B, and 0.2 part of coupling agent.

Description

technical field [0001] The invention specifically relates to a high-performance PET / PBT material for a junction box of an air conditioner compressor and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] PET (polyethylene terephthalate) resin is a milky white or light yellow highly crystalline polymer obtained by polycondensation of terephthalic acid and ethylene glycol. Its molecular structure is highly symmetrical and has a certain crystal orientation. Excellent weather resistance, good creep resistance, high fatigue resistance, low wear and high hardness, it is the toughest material in thermoplastics, its alloy resin has a wide range of applications, and can replace high-gloss materials such as ABS and other materials. Electrical, heat- and light-resistant functional parts. Although the unmodified PET raw material has high structural regularity and strong crystallization ability, its molecular chain is rigid...
