A kind of PC/ABS alloy material
Technical field
The present invention relates to a kind of macromolecular material Ji Intraoperative field, particularly relate to a kind of high molecule alloy material.
Background technology
PC/ABS is a kind of plastic alloy material of excellent property, and it not only has favorable mechanical performance and moulding processability, and product surface good luster, attractive in appearance, thereby is widely used in electronics, household electric appliances.
When the PC/ABS alloy is used to make electronics zero member, often require material to have flame retardant properties, to this, people adopt the method for adding fire retardant to improve the flame retardant properties of material usually.For preventing that further the molten drop phenomenon from appearring in material when carrying out combustion testing, it is fire-retardant to make material reach the UL94V-0 level, generally also need to cooperate a certain amount of Antidrip agent of adding, but the adding of Antidrip agent, the serious deterioration that can cause PC/ABS alloy material mechanical property (especially notched Izod impact strength), and the complexity that becomes of filling a prescription, formulation cost also can improve.
Summary of the invention
In view of above problem, the object of the present invention is to provide a kind of PC/ABS alloy material, this PC/ABS alloy material good mechanical performance, fire-retardant nothing drippage, combustionproperty reaches the UL94V-0 level.
For achieving the above object, PC/ABS alloy material provided by the invention, it mainly comprises following component, is expressed as with parts by weight:
PC 40~60
ABS 25~40
Organic silicon-acrylate multipolymer 3~8
Bromide fire retardant 6~15
Sb system fire retardant 2~5
Resins, epoxy 0.1~1
Oxidation inhibitor 0.1~0.3
Wherein, described bromide fire retardant can be brominated polycarbonate, decabromodiphynly oxide, eight bromo ether, tetrabromo-bisphenol, tetrabromobisphenol a polycarbonate oligopolymer, hexabromocyclododecane or environment-friendly type bromide fire retardant TDE etc.
Described Sb system fire retardant can be antimonous oxide, antimony peroxide or sodium antimonate etc.
Described oxidation inhibitor can be antioxidant 1010, oxidation inhibitor 2921 etc.
Preferably, PC/ABS alloy material provided by the invention, its component is expressed as with parts by weight:
PC 40
ABS 32
Organic silicon-acrylate multipolymer 8
Brominated polycarbonate 15
Antimonous oxide 5
Resins, epoxy 0.5
Oxidation inhibitor 0.2
Preferably, PC/ABS alloy material provided by the invention, its component is expressed as with parts by weight:
PC 50
ABS 29
Organic silicon-acrylate multipolymer 5
Brominated polycarbonate 12
Antimonous oxide 4
