Description
技术领域
本发明涉及一种模具，尤其涉及一种微流控芯片模具。
背景技术
高分子聚合物是制备微流控芯片的一种最常见的材料，由于高聚物具有材料成本和加工成本低廉、适合大批量生产制备等特点，特别适用于微流控芯片的科学基础研究和生产应用两大领域。目前的聚合物微流控芯片的加工方法，主要分为直接加工方法和间接加工方法，其中，基于模具复制的间接制备方法是现在最主要的聚合物芯片的加工方法，这种方法特别适合于聚合物芯片的批量制备，因此在微流控芯片的产业化中具有重要的位置。但是目前微流控芯片在使用过程中硬度不高，耐磨性差，不能满足生产的需求。
因此，为解决上述问题，特提供一种新的技术方案。

增塑剂 1-3份；
石膏 8-10份；
竹炭 3-5份；
铝粉 5-8份；
铁粉 20-25份。
进一步的，所述高分子聚合物为聚乙烯、聚丙乙烯、丁苯橡胶、顺丁橡胶或合成纤维其中的一种或两种组合。
进一步的，所述填充剂为硅藻土、石墨、炭黑、氧化铝粉或金刚砂。
进一步的，所述增塑剂为邻苯二甲酸二(2-乙基己)酯。
本发明的有益效果是：组分配合合理可靠，添加了铝粉和铁粉，能大大增强微流控芯片模具的耐磨性和强度，能有效的延长模具的使用寿命，大大降低了生产成本。
