Problems solved by technology

[0003] The flame retardant level of PC itself can reach the V-2 level in the UL94 standard formulated by the Insurance Laboratory of the United States, and has a certain flame retardant level, but when it is used in the field of electronic appliances, this flame retardant level cannot It meets the UL94V-0 flame retardant standard in the field of electronic appliances, so the material still needs to improve its flame retardant performance when it is further applied in the field of electronic appliances

Embodiment 1

[0019] Example 1 Weigh 100 parts by mass of PC, add 3 parts by mass of hexa-(formylphenoxy)-cyclotriphosphazene, add 0.2 parts by mass of 1010 antioxidant, add 0.2 parts by mass of 168 antioxidant, add polytetrafluoroethylene 0.5 parts by mass of vinyl fluoride anti-dripping agent. After physically blending the above materials, melt blending by twin-screw extrusion to form a flame-retardant PC composition with uniform dispersion of components. The composition reaches a 3.2mm thick spline UL94V -Class 0 flame retardant level.

Embodiment 2

[0020] Example 2 Weigh 100 parts by mass of PC, add 10 parts by mass of ABS resin, add 4 parts by mass of hexa-(formylphenoxy)-cyclotriphosphazene, add 0.2 parts by mass of 1010 antioxidant, add 168 parts by mass of antioxidant 0.2 parts by mass, add 0.5 parts by mass of polytetrafluoroethylene anti-dripping agent, after physical blending of the above materials, melt blending by twin-screw extrusion to form a uniformly dispersed flame-retardant PC composition of each component, the composition reaches 3.2mm thick spline UL94V-0 flame retardant level.

Embodiment 3

[0021] Example 3 Weigh 100 parts by mass of PC, add 20 parts by mass of ABS resin, add 7 parts by mass of hexa-(formylphenoxy)-cyclotriphosphazene, add 0.2 parts by mass of 1010 antioxidant, add 168 parts by mass of antioxidant 0.2 parts by mass, add 0.5 parts by mass of polytetrafluoroethylene anti-dripping agent, after physical blending of the above materials, melt blending by twin-screw extrusion to form a uniformly dispersed flame-retardant PC composition of each component, the composition reaches 3.2mm thick spline UL94V-0 flame retardant level.

Abstract

The invention relates to a high-efficiency antiflaming polycarbonate composition compounded by phosphazene compound. The antiflaming polycarbonate composition is prepared from polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), (aldehyde group-phenoxy)-cyclotriphosphazene series compound, antioxidant and anti-drip agent of fluoride by melting and compounding above-mentioned materials in certain proportion.

Description

technical field [0001] The invention relates to a polycarbonate composition compounded with phosphazene compounds and having high-efficiency flame-retardant properties. The invention belongs to the technical field of obtaining materials with flame-retardant properties by compounding and combining multiple materials. Background technique [0002] Polycarbonate (PC) has a light transmittance of more than 90% and an application temperature of more than 100°C. Therefore, as an engineering plastic, it has a wide range of applications in the fields of electronic appliances, decoration, packaging and household products. [0003] The flame retardant level of PC itself can reach the V-2 level in the UL94 standard formulated by the Insurance Laboratory of the United States, and has a certain flame retardant level, but when it is used in the field of electronic appliances, this flame retardant level cannot It satisfies the UL94V-0 flame retardant standard in the field of electronic ap...
