Example Embodiment

[0022] A preparation method of polycarbonate composite material for producing automobile lampshades, including the following steps:

[0023] (1) Preparation of polycarbonate composite material A:

[0024] a. Weigh the following parts by weight: bisphenol A polycarbonate 90, polyethylene terephthalate-1,4-cyclohexanedimethanol 20, ethylene-ethyl acrylate copolymer 8. Glyceryl behenate 2.5, zinc laurate 0.7, dipropylene glycol dibenzoate 12, monophenyl diisodecyl phosphite 0.9, hydroxyaluminum distearate 2, erucamide 3.5, phytate 0.4 , 2,6-Di-tert-butyl-4-methylphenol 0.3, Crestrozole trisiloxane 0.15, Resorcinol monobenzoate 0.1;

[0025] b. Take bisphenol A polycarbonate, glyceryl behenate, zinc laurate, phytate and cresoltrozole trisiloxane into the high-speed mixer, stir and mix until the material temperature reaches 70℃ , Add the remaining raw materials, continue to stir and mix until the material temperature reaches 85°C, transfer the materials to a double-roll mill for 8 minut...

Abstract

The invention discloses a preparation method for a polycarbonate composite for producing vehicle lamp housings. The method comprises the steps of preparation of a polycarbonate composite A, preparation of a polycarbonate composite B, preparation of a modifier and preparation of a polycarbonate composite finished product. The polycarbonate composite prepared with the method disclosed by the invention is excellent in comprehensive performance, not only has higher tensile strength, bending strength and notch impact strength, but also has excellent temperature resistance, flame retardance, abrasive resistance, fatigue resistance, weather resistance, aging resistance, acid-alkali corrosion resistance and the like, has long service life, can be widely applied to the vehicle lamp housings, and has wide market prospect.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a method for preparing a polycarbonate composite material used for producing polycarbonate for automobile lampshades. Background technique [0002] Polycarbonate resin is tasteless, odorless, non-toxic, transparent, and is a thermoplastic engineering plastic with excellent comprehensive properties. Due to its excellent comprehensive mechanical properties, high transparency, good flame retardancy, heat resistance, electrical insulation and dimensional stability, and low water absorption, it is widely used in the automotive industry and is suitable for production It is suitable for the production of various parts for cars and light trucks, mainly focusing on lighting systems, instrument panels, heating panels, defrosters and bumpers made of polycarbonate alloys. However, pure polycarbonate or ordinary polycarbonate materials still cannot meet the requirements for automotive lam...
