摘　　要：实验研究了填料类型、粒径大小和用量对PVC密封垫蒸发残渣卫生性能的影响。结果表明:4种填料均可用于水性和酒性产品包装的密封材料中,针状填料T4适宜于酸性产品密封料,油性产品密封料除优选填料外,还需对增塑剂进行筛选;填料目数越小,蒸发残渣越大,在可生产的黏度范围,可增加填料用量。The effects of filler type, particle size, and dosage on evaporation residue of PVC gasket were studied through experiments. The results showed that 4 kinds of filler can be used for PVC gasket in water-based and low-etha- nol product packaging; needle shaped filler T4 suits acidic food packaging; plasticizer needs to be filtrated except for filler in oily food packaging; the smaller the filler size is, the more evaporation residue shows; filler dosage can be added in producible range.
