【摘要】：为了改进水基拉延油在北方寒冷的冬天无法应用于钢板冲压车间的生产需求,本文选用乙二醇为添加剂,改善其应用范围。同时为了更方便的得出根据不同冲压件的拉延粘度需求所对应的水基拉延油的原料配比,建立了水基拉延油粘度模型。针对3个样品体系建立了粘度模型并验证。在不同的体系温度下,针对三种牛顿型与非牛顿型的混合体系的不同比例完全水溶性拉延油体系,以水和乙二醇为溶剂和稀释剂,对高粘度和固态组分进行稀释调节。将温度和稀释剂作为可调变量,利用线性最小二乘法和非线性最小二乘法对Eyring方程和方程参数模型进行联合回归计算,得到了用于预测该类体系粘度的四参数模型以及模型参数与助剂含量的关系式。其方程平均相对百分误差分别为A1:15.67%,A2:18.16%,B1:19.48%。该模型满足工程放大需求,可用于该混合体系的粘度预测。为了更好的适应生产需求,本文对水基拉延油的合成进行了放大处理。由于原料的更换,本文首先对三乙醇胺硼酸酯、三乙醇胺脂肪酸盐、水基拉延油的小试、中试合成路线进行了重新的探索和研究。通过对比试验、放大和粘度的测定,确定了水基拉延油的优选配方;然后,通过拉延油体系重度拉伸配方,向里面加入适量的水,配成8个样品体系,通过粘度的测定,确定了中度拉伸和轻度拉伸配方;最后,对9个水基拉延油样品进行了性能测试,经检测均符合使用要求。成功开发出适用于生产的水基拉延油配方,该重度拉伸、中度拉伸以及轻度拉伸配方对指导工业生产具有一定参考价值。
[Abstract]:In order to improve the production demand of water-based drawing oil in cold winter in northern China, ethylene glycol was chosen as additive. To improve its application scope. At the same time, in order to get the ratio of water based drawing oil according to the drawing viscosity requirement of different stamping parts more conveniently, The viscosity model of water-based drawing oil was established, and the viscosity model was established and verified for three sample systems. At different system temperatures, for the three Newtonian and non-Newtonian mixed systems, the completely water-soluble drawing oil system with different proportions was established. Using water and ethylene glycol as solvent and diluent, the high viscosity and solid components were diluted and adjusted. Temperature and diluent were used as adjustable variables. The linear least square method and nonlinear least square method are used to calculate the Eyring equation and the equation parameter model. The four-parameter model used to predict the viscosity of this kind of system and the relationship between the model parameters and the content of auxiliaries are obtained. The average relative percent error of the equation is A1: 15.67 and A2: 18.16 B1: 19.48. the model meets the needs of engineering amplification. It can be used to predict the viscosity of the mixed system. In order to better meet the demand of production, the synthesis of water based drawing oil has been amplified. Because of the replacement of raw materials, the triethanolamine borate and triethanolamine fatty acid salt are first used in this paper. The pilot synthetic route of water-based drawing oil was re-explored and studied. The optimum formula of water-based drawing oil was determined by contrast test, amplification and viscosity measurement, and then the heavy drawing formula was obtained by drawing oil system. By adding proper amount of water to it, eight sample systems were prepared, and the medium and light drawing formulas were determined by viscosity measurement. Finally, the properties of 9 water based drawing oil samples were tested. The water based drawing oil formula which is suitable for production has been successfully developed. The heavy, medium and light drawing formula has certain reference value for guiding industrial production.
