Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0018] A flame-retardant PC / PET composite material, the composition of which is: 48% PC, 20% PET, 5% ethylene-butyl acrylate-glycidyl methacrylate copolymer, 15% melamine polyphosphate %, 0.5% compound of polytetrafluoroethylene and polyvinylidene fluoride with a mass ratio of 4:1, 10% of acrylonitrile-butadiene-styrene copolymer, hindered phenolic antioxidant with a mass ratio of 1:1 The compound of 1010 and phosphite antioxidant 168 is 0.3%, and pentaerythritol stearate is 1.2%. Wherein, the PC is bisphenol A type aromatic polycarbonate; the PET is polyethylene terephthalate.

[0019] The preparation method is as follows: (1) Dry PC at 110°C-130°C for 3-4 hours in a blower dryer, and dry PET at 130°C-150°C for 3-4 hours, then use; (2) ), weigh the dried PC and PET according to the weight ratio, add them into the mixer and stir evenly, then add...

Abstract

The invention discloses a flame-retardant PC / PET composite material which comprises the following components in percentage by mass: 30-60% of PC, 10-30% of PET, 2-5% of a compatilizer, 5-15% of a flame retardant, 0.1-0.5% of an anti-melting dropping agent, 5-10% of a toughening agent, 0.1-0.5% of an antioxidant and 0.5-1.5% of a lubricant. The flame-retardant PC / PET composite material has the beneficial effects of being respective advantages of PC and PET, and good in compatibility, high in flame retardancy efficiency, high in impact resistance and low in cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant PC / PET composite material. Background technique [0002] PC / PET (polycarbonate / polyethylene terephthalate) composite material has excellent properties that PC and PET single components do not have, and can be used in many occasions, such as in household appliances, automobiles, machinery, construction, etc. has been widely used in the field. However, since PET is a crystalline polymer, PC is an amorphous polymer, and PC / PET is a typical amorphous / crystalline blend system, the compatibility of the two blends is relatively poor, resulting in poor toughness of PC / PET composites , the flame retardancy is not high, which limits its application in some fields. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant PC / PET composite material with high impact resistance modification efficiency, good flame-reta...
