Embodiment 1～10

[0057] Embodiments 1 to 10 are prepared by adopting two-step melt dispersion method:

[0058] (1) Pack 40 parts of titanium dioxide light-reflecting agent (Kronos titanium dioxide, Germany, model KRONOS2233, particle size 0.1-0.5 μm) and 12.5 parts of silane coupling agent (produced by Wacker, Germany, model A-171) Stir in a high stirring pot at a speed of 900r / min for 35 minutes, then mix 47 parts of polycarbonate (produced by Idemitsu Corporation, model IR1900), 0.2 parts of lubricant (produced by Italy Faji Corporation, model PETS AP) And 0.3 parts of antioxidant (produced by Jinhai Yabao, model AT-168 and Jinhai Yabao produced, model AT-76 is compounded by weight ratio 1:2) in high stirring pot with 700r / min speed stirring 10 minute. Then put the raw material mixture into the twin-screw extruder to prepare high-concentration reflective masterbatch after melting, extruding, cooling and pelletizing. The temperature of each section of the twin-screw extruder is 245°C, 260°C...

Abstract

The invention discloses a high-flame-resistance high-strength high-reflection polycarbonate material which is prepared from the following raw materials in percentage by mass: 10-75% of polycarbonate, 0.05-10% of a flame retardant, 0.1-0.8% of an anti-dropping agent, 25-75% of light-reflecting master batches, 1-10% of a toughening agent, 0.2-1% of an ultraviolet resistant agent, 0.2-1% of an antioxidant and 0.2-5% of a lubricant, wherein the light-reflecting master batches consist of a light reflecting agent, a coupling agent, polycarbonate and auxiliaries in a mass ratio being 40 to (7.5 to 17.5) to (37 to 57) to (0.1 to 5). The material has a good light shielding and reflecting function, high flame resistance, and good mechanical property. The invention further discloses a preparation method and application for the high-flame-resistance high-strength high-reflection polycarbonate material. The high-flame-resistance high-strength high-reflection polycarbonate material can be used for preparing a light reflecting piece, and is especially suitable for preparing an LED (light-emitting diode) lamp reflecting cover.

Description

technical field [0001] The invention relates to the technical field of light reflector materials, in particular to a high flame-retardant, high-strength, high-reflection polycarbonate material and its preparation method and application. Background technique [0002] Under the social background with the themes of green, energy saving, and environmental protection, light-emitting diode (LED) technology has opened up a new application field in lighting. With the continuous improvement and improvement of LED luminous efficiency and performance, in just a few decades, LED has gradually evolved from mature application fields such as indicator lights, mobile phone backlight displays, and traffic lights to medium and large-sized LCD backlights, home lighting, Market penetration of emerging applications such as automotive lighting. [0003] Since LED is a point light source with high luminous intensity, when it is applied to LED products for home and commercial lighting, it is neces...
