Abstract
This invention relates to a composition of recovered PC/ABS waste material. The composition is composed of: PC/ABS waste material 80-85 wt.%, impact modifier 13-17 wt.%, and flame retardant 2-5 wt.%. Modification by impact modifier and flame retardant can improve the mechanical performance and flame retardancy of recovered PC/ABS waste material. Therefore, recovered PC/ABS waste material can be effectively utilized, and is environmentally friendly. This invention also relates to the application of the composition of recovered PC/ABS waste material in molded products.
Description
Technical field
The present invention relates to PC/ABS (Polycarbonate/ABS Alloy, PC) disposable recovering composition, also relate to the application of this disposable recovering composition in resin manufacture.
Background technology
Cold burden, defective material or defective materials such as substandard products, recovery article that the PC/ABS resin is produced when injection molding are very many, and the treatment process to the PC/ABS defective material mainly comprises at present: (1) burns or land-fill method is handled.Owing in burning process, can produce sulfurous gas obnoxious flavoures such as (being the essential substance that forms acid rain), very easily cause environmental pollution; And take in the land-fill method processing because the refractory organics of PC/ABS also can cause very big harm to environment.Present this method is in the industry cycle progressively eliminated.(2) the PC/ABS defective material is simply reclaimed take out grain and do not carry out any modification, be downgraded to common plastics to use,, fail to make full use of the economic worth of these defective materials though solved problem of environmental pollution.(3) the PC/ABS defective material is reclaimed modification.Adopt of industry adds the mechanical property that coupling agent improves resin more when reclaiming PC/ABS at present, but the sold resin that this method modification forms only is applicable to the mechanical property of materials and the not high situation of accuracy requirement; And adopt acid anhydrides usually as coupling agent, in the course of processing, acid anhydrides can produce corrosion and the work-ing life of reduction equipment to molding device and mould.
Summary of the invention
The object of the present invention is to provide a kind of PC/ABS disposable recovering composition, the PC/ABS defective material is reclaimed modification, can make treated recovered material reusable, simultaneously environment is not had negative interaction.
For achieving the above object, PC/ABS disposable recovering composition of the present invention is to add properties-correcting agent, fire retardant and carry out blending in the PC/ABS defective material, the PC/ABS defective material is carried out modification, thereby improve its mechanical property and give flame retardant resistance.
A kind of PC/ABS disposable recovering composition provided by the invention comprises the following component of calculating by mass percentage:
(a) the PC/ABS defective material 80～85%
(b) impact modifier 13～17%
(c) fire retardant 2～5%
What wherein said impact modifier was polycarbonate, rubber content greater than in 50% ABS resin or MBS (MBS) resin is a kind of.
Wherein said fire retardant is a kind of in brominated polycarbonate, brominated polycarbonate, TDE or the decabromodiphynly oxide.
The content of bromine is 58% in the wherein said brominated polycarbonate.
Preferably, a kind of PC/ABS disposable recovering composition provided by the invention comprises the following component of calculating by mass percentage:
(a) the PC/ABS defective material 82.4%
(b) polycarbonate 14.6%
(c) brominated polycarbonate 3%
The content of bromine is 56-60% in the wherein said brominated polycarbonate, preferably 58%.
PC/ABS disposable recovering composition of the present invention adopts impact modifier to replace coupling agent of the prior art, and the PC/ABS defective material is reclaimed modification, makes it reach the service requirements of novel material and obtains economic recycling, can not cause extra burden to environment.
PC/ABS disposable recovering composition of the present invention can be made various forms of moulding product for utilization with the existing technical approach in present technique field.
