Embodiment 1

[0025] First, 0.2 grams of triphenyl phosphite, 0.2 grams of methyl methacrylate-butadiene-styrene terpolymer and 0.1 grams of polytetrafluoroethylene were added to 100 grams of powdered polycarbonate , and stirred in a high-speed mixing device, wherein the stirring time is 3 minutes; secondly, put the uniformly mixed mixture into a twin-screw extrusion device, and extrude after heating and melting, wherein the temperature of the twin-screw extrusion device is controlled At 220°C, the screw speed is controlled at 15 rpm; then, the extruded melt blend is cooled at room temperature and pelletized, and the obtained particles are polycarbonate resin; finally, the polycarbonate The ester resin is heated and melted at 220° C. by an extruder, extruded, and then processed and shaped by a molding die to obtain the polycarbonate film of this embodiment.

Embodiment 2

[0027] First, 0.2 grams of trinonylphenyl phosphite, 0.2 grams of acrylonitrile-butadiene-styrene copolymer, 0.1 grams of polytetrafluoroethylene and 5 grams of molecular formula C 9 h 20 o 6 P 2 The cyclic phosphate ester is added in 100 grams of powdered polycarbonate, and stirred in a high-speed mixing device, wherein the time of stirring is 5 minutes; secondly, the homogeneous mixture is put into a twin-screw extruder, Extrude after heating and melting, wherein the temperature of the twin-screw extrusion device is controlled at 250°C, and the screw speed is controlled at 45 rpm; then, the extruded melt blend is cooled at room temperature and then pelletized. The obtained particles are polycarbonate resin; finally, the polycarbonate resin is heated and melted at 250° C. through an extruder, then extruded, and then processed through a molding die to obtain the polycarbonate film of this embodiment.

Embodiment 3

[0029] First, 0.2 grams of triphenyl phosphite, 0.1 grams of styrene-butadiene thermoplastic elastomer, 0.2 grams of polytetrafluoroethylene, 5 grams of molecular formula C 15 h 31 o 9 P 3 The cyclic phosphate ester and 5 grams of potassium perfluorobutane sulfonate are added to 100 grams of powdered polycarbonate, and stirred in a high-speed mixing device, wherein the stirring time is 4 minutes; secondly, the mixed The homogeneous mixture is put into a twin-screw extrusion device, heated and melted, and then extruded. The temperature of the twin-screw extrusion device is controlled at 270 ° C, and the screw speed is controlled at 45 rpm; then, the extruded melt blended After the material is cooled at room temperature, it can be cut into pellets, and the obtained particles are polycarbonate resin; finally, the polycarbonate resin is heated and melted at 275°C through an extruder, then extruded, and then processed by a molding die. The polycarbonate film of this example was ...

Abstract

The invention relates to high-efficiency phosphorus flame retardant panlite, a preparation method and a film thereof. The panlite comprises the following components: makrolon, a phosphorus flame retardant, a fluorine flame retardant and an auxiliary agent, wherein the content of the phosphorus flame retardant accounts for 5-30 percent of the weight of the makrolon, the content of the fluorine flame retardan accounts for 0.1-10 percent of the weight of the makrolon, and the content of the auxiliary agent accounts for 0.1-10 percent of the weight of the makrolon. The film prepared from the high-efficiency phosphorus flame retardant panlite has good flame retardance and good shock resistance and also reduces the toxicity compared with an ordinary halogen flame retardant makrolon material whenexposed at high temperature; meanwhile, an addition agent containing chlorine or bromine is not used by the film. When the contents of the added phosphorus flame retardant and the fluorine flame retardant reach a certain quantity, the flame retardance of the film confirms to the standard of a UL94-VTM0 grade.

Description

technical field [0001] The invention relates to a carbonate resin, a preparation method and a film thereof, in particular to a high-efficiency phosphorus-based flame-retardant polycarbonate resin, a preparation method and a film thereof. Background technique [0002] Polycarbonate (PC) is one of the five widely used engineering plastics. It has comprehensive and balanced mechanical, electrical and heat resistance properties, especially known for its excellent impact strength and creep resistance, high light transmittance, and good mechanical properties. Especially impact toughness is the best among engineering plastics. Due to the excellent properties of polycarbonate, its products and its blended materials have been widely used in industries such as electronics, electrical appliances, machinery, automobiles, textiles, light industry and construction. [0003] Polycarbonate has a certain self-extinguishing property and emits CO when burning. 2 , its flame retardant perform...
