Description

Chain extension waste electrical equipment shell ABS plastic and preparation method thereof
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of chain extension waste electrical equipment shell ABS plastic and preparation method thereof.
Background technology
ABS plastic is a kind of interchangeable heat plastic resin with good impact performance and good moulding processability, and ABS plastic is because its combination property is remarkable, machine-shaping is convenient and has wide range of applications and obtains fast development.Current waste electrical equipment amount of plastic grows with each passing day; in these electric appliance casing plastics, ABS plastic occupies larger specific gravity; so scientificlly and effectively reclaiming and utilizing waste and old ABS plastic; act not only as the new forms of energy of 21 century; and be protection environment, realize the effective means of sustainable development, it is the important content developed a circular economy.
ABS is after life-time service, by the impact using environment, have a degree of aging, and the technical processs such as broken, extruding pelletization in removal process, injection moulding also can further speed up its ageing process, wherein the rubber phase degree of aging of toughness is provided to become apparent from for ABS, so the toughness of waste and old ABS declines by a big margin.Stop therefore, it is necessary to take measures or slow down the aging of waste and old ABS in removal process.
Summary of the invention
The present invention is in order to stop or slow down the aging of waste and old ABS in removal process, it is provided that a kind of chain extension waste electrical equipment shell ABS plastic and preparation method thereof.
The present invention is achieved by the following technical solutions: chain extension waste electrical equipment shell ABS plastic, and it is made up of the raw material of following weight portion, waste and old ABS100 part, epoxy resin 0.1～0.9 part.
Those skilled in the art, except adopting preparation method of the present invention, by conventional extruding and pelletizing process, can obtain chain extension waste electrical equipment shell ABS plastic of the present invention.
Through performance test, its notch impact strength of waste and old ABS of recovery is 1.56kJ/m2Left and right, hot strength is about 13.92MPa, and bending strength is about 39.16MPa, and bending modulus is about 1591.66MPa.By formula of the present invention, after adopting the extruding and pelletizing process of chain extender epoxy resin and routine, by injection machine, finished product being injection molded into standard testing batten, its notch impact strength is at least 1.5kJ/m2, hot strength is at least 13MPa, and bending strength is at least 39MPa, and bending modulus is at least 1500MPa.
Further, the preparation method of described chain extension waste electrical equipment shell ABS plastic, the steps include:
(1) broken worn-out ABS, weighs raw material by weight ratio；
(2) waste and old ABS put into 80 DEG C, pressure be 0.09MPa baking oven in vacuum drying 8h；Epoxy resin put into 30 DEG C, pressure be 0.09MPa baking oven in vacuum drying 8h；
(3) adding double screw extruder through the waste and old ABS after step (2) processes with epoxy resin Homogeneous phase mixing, extrusion temperature is 190～230 DEG C, discharging, and after extrusion, cooling, drying-granulating, get product.
But by preparation method of the present invention, by injection machine, finished product being injection molded into standard testing batten, its notch impact strength is at least 5kJ/m2, hot strength is at least 19MPa, and bending strength is at least 64MPa, and bending modulus is at least 2450MPa.
Chain extension waste electrical equipment shell ABS plastic of the present invention, employing epoxy resin is chain extender, the waste and old ABS plastic of chain extension of preparation has good mechanical property and processing characteristics, the impact property of waste and old ABS plastic, tensile property and bending property are all significantly improved, and drawing abillity improves, improve product strength.
