Abstract
The invention relates to a glass fiber reinforced ASA (acrylonitrile-styrene-acrylate copolymer)/PETG (polyethylene terephthalate glycol) alloy material and a preparation method thereof. The ASA/PETG alloy material is prepared from, by weight, 30-60 parts of ASA resin, 30-60 parts of PETG resin, 10-30 parts of glass fibers, 0.5-2 parts of a compatilizer, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant. The preparation method includes steps: (a) adding the ASA resin, the PETG resin, the compatilizer, the antioxidant and the lubricant into a mixer to realize mixing; (b) after side feeding of the glass fibers and main feeding of a mixture obtained at the step through a double-screw extruder, blending and granulating to obtain the material. The method is simple and feasible; by the compatilizer, the ASA, the PETG and the glass fibers are combined more steadily, and the glass fiber reinforced ASA/PETG alloy material has excellent mechanical properties, fluidity and dimensional stability and suitable for automotive complex structural interior decoration parts such as speaker covers and defogging grilles.
Description
technical field [0001] The invention belongs to the fields of polymer blending and polymer molding processing, and in particular relates to a glass fiber reinforced ASA / PETG alloy material and a preparation method thereof. Background technique [0002] ASA resin (acrylonitrile-styrene-butyl acrylate copolymer) is a thermoplastic polymer material structure with high strength, good toughness, good light resistance, and easy processing and molding. [0003] PETG is a transparent, non-crystalline copolyester. The common comonomer of PETG is 1,4-cyclohexanedimethanol, which is called polyethylene terephthalate-1,4-cyclohexanedimethanol. ester. It is a polycondensation product of three monomers of terephthalic acid (PTA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM) by transesterification. Compared with PET, it has more 1,4 -Cyclohexanedimethanol comonomer has more ethylene glycol comonomer than PCT, so the performance of PETG is quite different from PET and PCT. P...
