耐热级ABS树脂耐候性能研究I.ABS树脂基材的影响

The Influence of ABS Base Resin I.on the Weathering Performance of Heat Resistant ABS Resin

本文主要采用紫外灯光照老化试验,分别研究了本体法ABS树脂及乳液法ABS树脂的耐候性能。发现本体法ABS树脂的橡胶粒径和树脂的流动性,乳液法ABS树脂中基体SAN树脂的AN含量和分子量是分别影响它们耐候性能的主要因素。

The weathering performance of bulk researched by the ultraviolet light aging test polymerized and emulsion polymerized of ABS resins was It is indicated that the rubber particle size and the flowing of the bulk polymerized ABS resin, the content of AN in SAN matrix resin and the molecular weight of SAN matrix resin in emulsion polymerized ABS resin are the main factors of the weathering performance.
