一种电老化实验的样品制备方法及模具
摘要：
本发明公开了一种用于电老化实验的样品制备方法及模具，旨在解决电老化实验时电极间电晕放电对电老化实验的影响的问题。一种用于电老化实验的样品制备方法：一、在两个精加工的不锈钢电极相对面上放入聚酯膜垫片；二、将与聚乙烯在混炼式转矩流变仪熔融共混后制成的样品颗粒放入两个电极之间；三、在电极和样品整体外套上一个环形金属圈；将整体放入平板硫化机进行成形处理，出模得到样品。本发明能有效避免电老化实验时电极间产生电晕放电。
摘要（英）：

The invention discloses a sample preparation method and mold for an electric aging experiment, and aims at solving the problem of the influence of corona discharging between electrodes on the electricaging experiment when the electric aging experiment is conducted. The method comprises the steps that one, polyester film cushioning pieces are placed on the opposite surfaces of the two fine processing stainless steel electrodes; two, sample granules prepared after melting blending in a blending torque rheometer together with polyethylene is conducted are placed between the two electrodes; three, a circular metal ring sleeve the integration of the electrodes and a sample; the integration is placed into a press vulcanizer to conduct shaping processing, and the sample is obtained after mold unloading is conducted. The method can effectively prevent corona discharging between the electrodes when the electric aging experiment is conducted.
