Halogen-free flame-retardant enhancement type polycarbonate composition

Abstract

The invention relates to a halogen-free flame-retardant enhancement type polycarbonate composition, which belongs to the field of polymer alloy, and consists of the following ingredients in parts by weight: 606-805 parts of PC-based resin, 100-300 parts of glass fiber, 40-60 parts of main flame retardant, 20-40 parts of flexibilizer, 3 parts of anti-dripping agent, 5-10 parts of lubricant and 4-6parts of antioxidant. The halogen-free flame-retardant enhancement type polycarbonate composition proposed by the technical scheme not only has the characteristics of high rigidity, heat resistance and good dimensional stability, but also has good processibility and fire resistance, and also has beautiful appearance, has no glass fiber exposed to the outside, and can be served as the special material of electrical products.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant reinforced polycarbonate composition, which belongs to the field of polymer alloys. Background technique [0002] This application relates to a method of imparting flame retardant properties to glass fiber reinforced polycarbonate resins, to compositions used in the method, and to such flame retardant polycarbonate resins produced by the method. [0003] Glass fiber reinforced polycarbonate resin has high strength and good appearance, and is widely used in the casing of various electrical appliances, especially suitable for injection molding of thin-walled parts. However, glass fiber reinforced polycarbonate resins are inherently flammable and the material can also melt and drip when heated, causing adjacent materials to catch fire. Therefore, in order to safely use glass fiber reinforced polycarbonate in many applications, effective flame retardants must be added to the material. Flame retardan...

Problems solved by technology

Fluorine compounds are expensive, and these materials alone do not work well with glass fiber reinforced polycarbonate resins, and in fact require additional additives, generally bromine-containing flame retardants

Due to the high processing temperature of glass fiber reinforced PC, the flame retardant used for PC requires a relatively high thermal decomposition temperature, and most of them are brominated high polymers, such as brominated polycarbonate, etc., so the price is expensive

[0005] With the implementation of the European Union ROHS Directive, the call for non-halogenated materials is getting higher and higher, and more and more manufacturers require that electrical products do not contain halogens. Ran researched and launched their own wares, but generally expensive
