采血管用聚酯切片母粒、制备方法及应用
摘要：
本发明涉及一种采血管用聚酯切片母粒，包括聚对苯二甲酸乙二醇酯切片；其特征为在聚酯切片中还含有流变改性剂和流变改性促进剂；流变改性剂为聚酯多元醇或/和硬脂酸盐或/和褐煤酸及其衍生物(皂、酯)或/和聚乙二醇；流变改性剂在整个材料中的含量为1～10重量%；流变改性促进剂为有机硅树脂；流变改性促进剂在整个材料中的含量为0.1～1重量%。本发明还涉及采血管用聚酯切片母粒的制备方法和应用。本发明具有的优点为能提高采血管用聚酯切片的熔体流动性。
摘要（英）：

The invention relates to polyester chip masterbatch for a blood sampling tube. The polyester chip masterbatch contains a polyethylene glycol terephthalate slice and is characterized in that the polyethylene glycol terephthalate slice further contains a rheology modifier and a rheology modification accelerant, wherein the rheology modifier is polyester polyol or/and stearate or/and montanic acid and their derivatives (soap and ester) or/and polyethylene glycol, the rheology modifier accounts for 1-10% of the weight of the whole material, and the rheology modification accelerant is organic silicon resin and accounts for 0.1-1% of the weight of the whole material. The invention further relates to a preparation method and application of the polyester chip masterbatch for the blood sampling tube. The polyester chip masterbatch has the advantages that the melt fluidity of the polyester chip masterbatch for the blood sampling tube is improved.
