Problems solved by technology

The mechanical properties of the hydrolyzed resin decrease, which seriously affects its use in some specific fields
[0003] In addition, in the application fields that require flame retardancy, the commonly used phosphate ester flame retardant for PC has the advantages of environmental protection, flame retardancy and high efficiency, but its addition usually produces plasticizing effect on PC, which affects the toughness and heat resistance of PC resin.
In addition, in high-temperature and high-humidity environments, the use of phosphate ester flame retardants is more likely to cause PC degradation. Therefore, the use of aromatic phosphate ester flame retardants in high-temperature and high-humidity environments is limited.

Abstract

The invention provides a difficult-flammble polycarbonate composition and a preparation method thereof. The difficult-flammble polycarbonate composition comprises the following components in parts byweight: 96.0-99.8 parts of polycarbonate resin, 0.1-3.0 parts of a toughening agent, 0. 01-6.0 parts of a flame retardant, 0.1-5.0 parts of an anti-hydrolysis agent, 0.01-2.0 parts of an antioxidant,and 0.01-1.2 parts of other additives; wherein the anti-hydrolysis agent is one of carbodiimide, isocyanate, oxazoline, and an epoxy compound. The difficult-flammble polycarbonate composition has goodflame retardation performance, toughness and anti-hydrolysis performance, the heat resistance temperature is higher than 120 DEG C, and the difficult-flammble polycarbonate composition is especiallysuitable for occasion with high usage environment requirements.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a flame-retardant polycarbonate composition and a preparation method thereof. Background technique [0002] Polycarbonate resin is a kind of general-purpose engineering plastic, which has the advantages of transparency, impact resistance, heat resistance, dimensional stability, etc., and because of its excellent characteristics mentioned above, it is widely used in industry as automotive, Materials in the field of office equipment such as printers, and in the electrical and electronic fields such as mobile phones. The polycarbonate commonly used in the market is prepared by the interfacial polycondensation method, which contains a large number of ester groups. When the temperature is high or the relative humidity is high, water easily reacts with polycarbonate and degrades with the help of heat and oxygen, and the hydrogen free radicals generated by the ...
