Problems solved by technology

(2) Simply recycle and granulate PC / ABS spray paint waste without any modification, and use the grade as filler. Although it is better than the above method, it still fails to fully utilize the value of PC / ABS
(3) Modification and recycling of PC / ABS spray paint waste, but because the paint film on the surface becomes magazines inside, it is very difficult to recycle, and the performance of recycled materials is not good

Embodiment 1

[0046] Take PC / ABS spray paint waste, PC / ABS raw materials, epoxy resin, coupling agent, antioxidant, brominated polycarbonate and impact modifier, and blend all the raw materials according to the following composition formula:

[0047] (a) PC / ABS spray paint waste 40 parts

[0048] (b) 54 PC / ABS raw materials

[0049] (c) 1.9 parts of epoxy resin

[0050] (d) 0.08 parts of coupling agent A-186

[0051] (e) Antioxidant 1076 0.1 part

[0052] (f) 2 parts of brominated polycarbonate (58% bromine content)

[0053] (g) Acrylic impact modifier 2 parts

[0054] Then the blended material is mixed and granulated in an extruder, and the resulting mixed and granulated product is made into a finished product by injection molding. Finally, the mechanical properties of the finished product are tested according to the national standard GB13525 / T-92 and the UL94 standard of the American Electrotechnical Association. The flame retardant performance was tested, and the results were compa...

Abstract

The invention discloses a dispense of PC / ABS alloy of PC / ABS lacquering waste material modify, which is characterized by the following: comprising 50-70 wt PC / ABS lacquering waste material, 20-65 wt PC / ABS raw material, 1-3 wt epoxide resin, 0. 08-0. 12 wt coupling agent, 0. 1-0. 5 wt anti-oxidant, 2-9 wt bromide polycarbonate and 2-5 wt impact resistance modifier; adopting PC / ABS lacquering waste material; adding into modifier; proceeding reclaiming modify for PC / ABS lacquering waste material; making the PC / ABS lacquering waste material reach demand of production and technical indication. This invention adopts now technical mode to produce miscellaneous product, which possesses better economical and social benefit.

Description

technical field [0001] The invention relates to the field of thermoplastic resin compositions in polymer material technology, in particular to a PC / ABS (Polycarbonate / ABS Alloy, polycarbonate / acrylonitrile-butadiene-styrene) spray paint waste modified into flame-retardant PC / ABS Formulation of ABS alloy. Background technique [0002] PC / ABS resin will produce a lot of waste in the surface painting process. At present, the treatment methods for PS / ABS painting waste mainly include: (1) Treating by incineration or landfill, but this method is not only uneconomical but also harmful It will bring environment and bring environmental pollution, such as incineration will produce harmful gases such as sulfur dioxide, which is the main cause of acid rain; and the use of landfill PC / ABS is not easy to degrade, which also causes great harm to the environment. At present, this method has been phased out in the industry. (2) Simply recycle and granulate the PC / ABS spray paint waste wi...
