Embodiment 1～9

[0030] According to the composition and content ratio of Table 1 to Table 3, use a high-speed mixer (SuperMixer) to mix evenly, and use a program file (process file) to use a twin screw extruder (twin screw extruder) at a temperature of 250 to 290 ° C. out of the shape, and then cut into pellets (pellet). Granular (Pellet) samples are injection molded at a temperature of about 280-300°C, and fully conditioned at room temperature to produce test pieces. The physical properties of the test pieces were measured by the following methods, and the results are listed in Tables 1-3. In addition, known additives may be added as mentioned above, and the usage amount is 0.25 wt% relative to the total weight of the composition.

[0031] For the purpose of evaluating the flame retardancy of the above-mentioned test pieces, polycarbonate resin compositions were extruded according to different contents of potassium perfluorobutane sulfonate and acrylic modified polytetrafluoroethylene, and ...

Abstract

The invention provides a halogen-free fire-retarding ponlite polycarbonate resin composite, composed of 98.55-99.65 weight percent of ponlite polycarbonate resin, 0.05-0.5 weight percent of perfluoroalkane sulfonate and 0.2-1.0 weight percent of acrylic modified polytetrafluoroethylene. The environment friendly material has excellent fire-retarding performance and strong color expressivity; and the existing physical properties of the material are not degraded.

Description

technical field [0001] The present invention relates to a halogen-free flame-retardant polycarbonate resin composition. Specifically, the present invention relates to a flame retardant containing perfluoroalkyl sulfonate and acrylic modified polytetrafluoroethylene. Background technique [0002] Generally, polycarbonate resins are thermoplastics that are commonly used in various commercial applications in the fields of electronics / electrical appliances and automobiles due to their excellent rigidity and transparency. However, polycarbonate resin is not an absolute flame retardant material. Under high temperature conditions, dripping molten substances can ignite surrounding substances. Therefore, in order to safely use polycarbonate resins in various applications, it is necessary to add additives that suppress the flammability of the above substances. [0003] Flame retardancy and drip resistance are described in U.S. Patent Nos. 3,971,756, 4,028,297, 4,110,299, 4,130,530, ...
