preparation example Construction

[0058] The preparation method of the small particle size core-shell polymer (D) can be selected from the commonly used methods, such as emulsion polymerization, suspension polymerization, etc., by allowing the core polymer and the shell polymer to polymerize react to graft the shell polymer to the core polymer.

[0059] Preferably, the core layer polymer comprises, but is not limited to, a diene-based rubber polymer, such as a rubber polymer of butadiene, a rubber polymer of isoprene, or a rubber of diene and vinyl aromatic monomers. Copolymers such as butadiene-styrene rubber copolymer or isoprene-styrene rubber copolymer.

[0060] Preferably, the monomers used to polymerize the shell polymer include but are not limited to (1). Styrene (styrene) compounds: styrene, α-methylstyrene (α-methylstyrene), halogen-substituted benzene Ethylene, hydrocarbon-substituted styrene; (2). Acrylonitrile (acrylonitrile) compounds: methacrylonitrile (methacrylonitrile); (3). (Meth) acrylate c...

[0073] According to the type and dosage of each component in Table 1, polycarbonate (A) (manufacturer: Chimei Wonderlite, trade name: PC-110), polyfluororesin (C) (manufacturer: MitsubishiRayon, trade name: A- 3750), RDX (B2) (manufacturer: Daihachi Chemical, trade name: PX-200) and small particle size core-shell polymer (D) (manufacturer: Kaneka, trade name: M-732) with a high-speed mixer Uniformly mix to form a mixture, put the mixture into the main feed hopper of the twin-screw extruder (mixing temperature is 270° C.), and then BDP (B1) (manufacturer: ADEKA, trade name: FP-600) by Side feeding into the twin-screw extruder, the mixture is mixed with (B1) and pelletized to obtain a polycarbonate composition.

[0074] Next, the polycarbonate composition was made into a test sample by an injection molding machine (injection molding temperature was 260 to 280° C.) and evaluated. The results are shown in Table 1.

Abstract

The present invention relates to a polycarbonate composition and the application thereof. The polycarbonate composition includes a polycarbonate (A), a first phosphate compound (B1), a second phosphate compound (B2), a polyvinyl fluoride resin (C) and a small size of core-shell polymer (D); the diameter thereof is less then 0.2[mu]m. The polycarbonate composition has better low temperature impact resistance and fire resistance via appropriate dosage of the first phosphate compound (B1), the second phosphate compound (B2), and the small size of core-shell polymer (D), molding products made by the polycarbonate composition's subsequent application are suitable for using in cold regions.

Description

technical field [0001] The present invention relates to a polycarbonate composition and its application, in particular to a polycarbonate composition comprising a core-shell polymer with a particle diameter of less than 0.2 μm, and a polycarbonate composition utilizing the polycarbonate composition Molded products made of objects. Background technique [0002] In recent years, due to the advantages of impact resistance, light weight per unit volume, easy processing, and strong insulation, polycarbonate resin has been widely produced and used in the fields of optoelectronics, biotechnology, and credit electronics. [0003] When products made of polycarbonate resin (such as computer casings, mobile phone casings, etc.) are used with heating elements (such as motherboards, circuit boards), the instantaneous temperature may be too high due to improper operation or damage of the heating elements, making the product Polycarbonate resin cannot withstand the instantaneous temperatu...
