【摘要】：為了改進(jìn)水基拉延油在北方寒冷的冬天無法應(yīng)用于鋼板沖壓車間的生產(chǎn)需求,本文選用乙二醇為添加劑,改善其應(yīng)用范圍。同時為了更方便的得出根據(jù)不同沖壓件的拉延粘度需求所對應(yīng)的水基拉延油的原料配比,建立了水基拉延油粘度模型。針對3個樣品體系建立了粘度模型并驗(yàn)證。在不同的體系溫度下,針對三種牛頓型與非牛頓型的混合體系的不同比例完全水溶性拉延油體系,以水和乙二醇為溶劑和稀釋劑,對高粘度和固態(tài)組分進(jìn)行稀釋調(diào)節(jié)。將溫度和稀釋劑作為可調(diào)變量,利用線性最小二乘法和非線性最小二乘法對Eyring方程和方程參數(shù)模型進(jìn)行聯(lián)合回歸計(jì)算,得到了用于預(yù)測該類體系粘度的四參數(shù)模型以及模型參數(shù)與助劑含量的關(guān)系式。其方程平均相對百分誤差分別為A1:15.67%,A2:18.16%,B1:19.48%。該模型滿足工程放大需求,可用于該混合體系的粘度預(yù)測。為了更好的適應(yīng)生產(chǎn)需求,本文對水基拉延油的合成進(jìn)行了放大處理。由于原料的更換,本文首先對三乙醇胺硼酸酯、三乙醇胺脂肪酸鹽、水基拉延油的小試、中試合成路線進(jìn)行了重新的探索和研究。通過對比試驗(yàn)、放大和粘度的測定,確定了水基拉延油的優(yōu)選配方;然后,通過拉延油體系重度拉伸配方,向里面加入適量的水,配成8個樣品體系,通過粘度的測定,確定了中度拉伸和輕度拉伸配方;最后,對9個水基拉延油樣品進(jìn)行了性能測試,經(jīng)檢測均符合使用要求。成功開發(fā)出適用于生產(chǎn)的水基拉延油配方,該重度拉伸、中度拉伸以及輕度拉伸配方對指導(dǎo)工業(yè)生產(chǎn)具有一定參考價值。
[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.
