摘要：本文旨在合成模具清洗胶，并对未经硫化的洗模胶与硫化后的胶进行性能的分析与解释。实验得出加了清洗成份的胶料对比没加清洗成份的有非常明显的清模效果。同时，在合成阶段我尝试了多种清洗成份的液体配合剂。发现硬脂酸和硬脂酸钙的加入有利于粘附性的降低，从而易于脱模。钛白粉的加入可以增加其拉伸强度和硫化速率指数。在分析合成胶粘附性时采用的是DMA的夹心剪切模式，测量样品的剪切模量与损耗因子来反应洗胶的粘弹性。发现含清洗配方的洗模胶G’对比无清洗剂的有较大的下降。在试验不同的小料和填料的批次时发现胶料的G’有的增加也有的有减小。70031

Study on Preparation and Adhesion Properties of Mold Cleaning
Abstract: The purpose of this paper is to synthesize mold cleaning glue and analyze and explain the performance of non-vulcanized mold glue and vulcanized rubber. Experiments show that the addition of the cleaning composition of the compound did not add cleaning ingredients have a very clear effect of the clear mold. At the same time, in the synthesis stage I tried a variety of cleaning ingredients of liquid compounding agent. It was found that the addition of stearic acid and calcium stearate favors the decrease in adhesion and thus easy release. The addition of titanium dioxide can increase its tensile strength and vulcanization rate index. In the analysis of the adhesion of synthetic adhesives used in the DMA sandwich shear mode, measuring the shear modulus of the sample and the loss factor to respond to the viscoelasticity of the wash. Found that the cleaning agent with the cleaning agent G' compared to no cleaning agent has a greater decline. In the test of different small materials and fillers of the batch found that the compound of the G' increase also some have reduced.
