Filler master batch and preparation method thereof

The invention discloses a filler master batch. The filler master batch is prepared from the following components in parts by weight: 80-97 parts of fillers, 0.2-1 part of an activating agent and 3-18 parts of a binding agent, wherein the binding agent is at least one of paraffin wax, polyethylene wax, oxidized polyethlene wax and ethylene-acrylic acid wax. The invention further provides a preparation method of the filler master batch. Compared with the prior art, the filler master batch has no carriers, so that carrier resin and product resin do not need to be consistent in a use process and the utilization limitation of the filler master batch is small. The preparation method does not utilize an extruder and an internal mixer, so that the machining cost is relatively low. 本发明公开了种填料母料，包括以下组分及其重量份：填料80-97份、活化剂0.2-1份、粘合剂3-18份；粘合剂为石蜡、聚乙烯蜡、氧化聚乙烯蜡、或乙烯-丙烯酸蜡中的至少种。本发明还提供了种填料母料的制备方法。与现有技术相比，本发明填料母料无载体，因此，在使用时载体树脂与产品树脂不是必须致，填料母料使用的局限性小。本发明的制备方法不使用挤出机和密炼机，使得加工成本更低。
