Abstract

The invention discloses a polycarbonate alloy and a preparation method thereof. The preparation method comprises the following steps: weighting the following components by weight percentage, 20-80 percent of polycarbonate, 80-20 percent of modified copolyester PCTG, 0.1-1.0 percent of antioxidant, 0.01-0.5 percent of toner, and 0.01-0.5 percent of ultraviolet absorber, pouring the weighed components into a mixer, mixing the components, placing the components in an extruder for melting, and extruding for granulation. Since the modified copolyester PCTG is added to modify the polycarbonate, the polycarbonate alloy with low cost and good toughness can be obtained.

Description

A kind of polycarbonate alloy and preparation method thereof
[technical field]
The present invention relates to technical field of polymer materials, relate in particular to a kind of polycarbonate alloy and preparation method thereof.
[background technology]
Polycarbonate is a kind of water white indefiniteness thermoplastic material, have heat-resisting, shock resistance, fire-retardant, advantages such as favorable mechanical performance are all arranged in common use temperature, be widely used in electronics, electrical equipment, container package, fields such as finishing material.But its defective aspect proof stress has seriously restricted its application in other field.
[summary of the invention]
The present invention is directed to the above-mentioned defective of prior art, a kind of polycarbonate alloy and preparation method thereof is provided, with the toughness of reinforced polycarbonate.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of polycarbonate alloy and preparation method thereof takes by weighing following component by weight percentage: polycarbonate 20-80%, modified copolyesters PCTG80-20%, oxidation inhibitor 0.1-1.0%, toner 0.01-0.5%, UV light absorber 0.01-0.5%; Pour each component that takes by weighing into stirrer and stir, and place forcing machine fusion extruding pelletization then.
Wherein, described polycarbonate is powdery or granular or powdery and granulous mixture.
Wherein, oxidation inhibitor is 4, the mixture of a kind of or its arbitrary combination in 4 '-thiobis (the 6-tertiary butyl-3-methylphenol), tris phosphite (2, the 4-di-tert-butyl-phenyl), four [β-(3, the 5 di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
Wherein, UV light absorber is a Whitfield's ointment dihydroxyphenyl propane ester, 2-hydroxyl-4 n-octyloxies-benzophenone, 2, the 4-dihydroxy benaophenonel, the mixture of a kind of or its arbitrary combination in 2-(2 '-dihydroxyl-the 3 '-tertiary butyl-5 '-aminomethyl phenyl)-5-chlorobenzotriazole.
Wherein, forcing machine is a single screw extrusion machine, and the temperature in each district of forcing machine is: a district 270-285 ℃, two district 280-290 ℃, three district 285-295 ℃, four district 290-300 ℃, five district 290-300 ℃.
As can be seen from the above technical solutions, the present invention carries out modification by adding modified copolyesters PCTG to polycarbonate, kept polycarbonate heat-resisting, shock resistance, fire-retardant, also obtain to have good toughness in the time of the favorable mechanical performance, chemical resistance, high tear resistance and good processing properties, the toughness of more common polycarbonate is significantly improved.Because modified copolyesters PCTG is lower than polycarbonate price, so the cost of the polycarbonate alloy of equivalent is lower than polycarbonate.
