对以石蜡、地蜡和松香等为原材料配制的石蜡-地蜡系中温模料配方进行了优化研究。通过改变不同原材料成分配比,研究考察各组模料的线收缩率、抗弯强度、显微硬度、熔点和粘度等性能指标。结果表明,当地蜡含量50%,石蜡40%,松香10%时,模料综合性能最优。 Paraffin wax, wax and rosin as raw materials for the preparation of paraffin wax - wax system temperature mold formulations were optimized. By changing the composition of different raw materials, the research investigated the linear shrinkage, flexural strength, microhardness, melting point and viscosity of each group. The results show that when the local wax content is 50%, the paraffin wax is 40% and the rosin is 10%, the comprehensive performance of the mold is the best.
