Description

一种高温精密铸造蜡
技术领域：
本发明涉及一种精密铸造模料领域，具体讲是一种高温精密铸造蜡。
背景技术：
国内精密铸造蜡目前开发的品种少，产量低，质量差，难以满足精密铸造工业发展的需要，尤其是高温精密铸造蜡，存在抗弯曲强度和收缩率较差的问题，使得蜡模型强度不高，尺寸不稳定。
发明内容：
本发明所要解决的技术问题是，提供一种使得蜡模型尺寸稳定且强度高的高温精密铸造蜡。
本发明的技术解决方案是，提供一种高温精密铸造蜡，以重量百分比计，包括下列组分：
聚乙烯蜡3-10％，石蜡40-65％，EVA蜡40-65％。
作为优选，以重量百分比计，包括下列组分：聚乙烯蜡5％，石蜡50％，EVA蜡45％。
进一步的，还包括熔融强度增强剂1-2％，碳九树脂1-5％，该熔融强度增强剂为丙烯酸共聚物。
本发明的有益效果是：本高温精密铸造蜡强度高，形成的蜡模型尺寸稳定性好，结构稳定，强度高，适合加工温度为75-80℃。
具体实施方式：
下面结合具体实施方式对本发明作进一步说明：
一种高温精密铸造蜡，以重量百分比计，包括下列组分：聚乙烯蜡5％，石蜡50％，EVA蜡45％。
本高温精密铸造蜡强度高，形成的蜡模型表面光洁、尺寸稳定性好。经试验，针入度(25℃，1/10mm)为1.27，收缩率为0.61％，抗弯强度为14.53MPa，加工温度为78.7℃，符合高温铸造蜡要求。且本配方组分简单，制备工艺可按常规工艺制备即可。
或者，也可以对上述比例进行调整，聚乙烯蜡5％，石蜡45％，EVA蜡50％，相比上一个配比而言，其强度会增强，经测试，抗弯强度可达15.37MPa。
另外，还可包括熔融强度增强剂1％和碳九树脂2％，并相应调整PVC石蜡44％，EVA蜡48％。检测后发现，针入度(25℃，1/10mm)为1.24，收缩率为0.59％，抗弯强度为16.05MPa，加工温度为79.1℃。
本高温精密铸造蜡强度高，形成的蜡模型尺寸稳定性好，结构稳定，强度高。
