Embodiment 1

[0029] This embodiment includes the following steps:

[0030] 1) The polycarbonate used in the following examples is bisphenol A polycarbonate PClexan141R of GE Company, with a molecular weight of 25000-28000 g / mol. The acrylonitrile-styrene-acrylate graft copolymer is Taiwan Chimei PW957, and the content of acrylate rubber is 40-80% by weight. Antioxidant uses tetrakis [β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, trade name is Irganox1010, produced by Swiss Ciba Specialty Chemicals. The present invention uses the ZE-25 twin-screw extruder that German Berstorff company produces.

[0031] This embodiment includes the following steps:

[0032] 1) Preparation of grafted ASA-g-MAH:

[0033]First, 80 parts of ASA, 20 parts of MAH, 1.5 parts of dicumyl peroxide (DCP), and 0.1 part of hindered phenolic antioxidant 1010 were uniformly mixed with a high-speed mixer for 5 minutes and then added to a twin-screw extruder for melting For blending, the tempe...

Abstract

The invention provides anti-hydrolysis anti-static PC / ASA alloy and a preparation method thereof. According to the method, condensation polymerization is conducted on PPR-MWCNT compounds and ASA-g-MAH grafted copolymer through bisphenol A and epoxy chloropropane, bisphenol A epoxy resin (EP-E51) and polycarbonate (PC) are obtained and are subjected to blending extrusion, and the anti-hydrolysis anti-static PC / ASA alloy is obtained. The prepared anti-hydrolysis anti-static PC / ASA alloy has excellent anti-static performance and excellent hydrolysis resistance, is suitable for the moist rainwater weather, has excellent impact toughness and lower processing viscosity, is easy to process and suitable for mass production and popularization, and can be oriented to automobile inside and outside ornaments such as an automobile rearview mirror shell body and an automobile door plank and outdoor sport equipment.

Description

technical field [0001] The present invention relates to a method in the technical field of polymer materials, in particular to a hydrolysis-resistant and antistatic polycarbonate (PC) / acrylonitrile-styrene-acrylate graft copolymer (ASA) alloy and a preparation method thereof . Background technique [0002] The polyacrylate rubber in the rubber core layer of the ASA graft copolymer is a saturated structure without residual double bonds, and dissociates under high-energy light with a wavelength below 300nm. This high-energy light does not exist in the sun’s rays on the earth, that is, ASA The molecular structure of the resin is not easily decomposed by high-energy light, so PC / ASA has high weather resistance. PC / ASA alloy can combine the excellent properties of PC and ASA, improve the heat resistance, impact resistance and tensile strength of ASA, reduce the viscosity of PC melt, improve processing performance, reduce the internal stress of products, and significantly improve...
