Leather based varnish was prepared with self - prepared prepolymer . the capability testing suggested that glossiness is > 110 % , resistance to cracking is > 30000 times , resistance to acetone is > 200 times and adhesion is well . in the study of uv printing ink suggested that when the pea / bpua ( wt ) is 3 / 1 - 4 / 1 , the coating film had good capability : adhesion is well , glossiness is > 110 % and tenderness is 1mm 在研制纸印品uv上光油和油墨的应用实验中，讨论了颜料与引发剂的配伍性、颜料的用量对光固化速度的影响，并对pea和bpua两种树脂的共混比例进行了研究，结果显示pea bpua = 3 1 - 4 1时，固化后性能测试显示：附着力合格、光泽度100 ，柔韧性1mm ，综合性能良好。
The development status and trend of gasoline engine oil at home and abroad are described in this paper . the tribology and lubrication characteristic and lubrication mechanism of the main tribo - pairs of gasoline engine are analyzed simply . in this paper base oil and some additives are chosen reasonably according to the lubricantions principal and a lot of data . the uniform design of experiment is used to arrange multi - level and multi - factor experiments . the stepwise technique is adopted to analyze the result . the sensitivity and compatibility among additives and the base oil are studied by a series of tests . on the basis of analyzing the low temperature capability the optimum of 15w / 40 sh gasoline engine oil is presented . at last , the property of this formulation is evaluated by comparing with the imports . the test result shows that their qualities are equivalent 本文介绍了国内外汽油机油的发展现状以及发展趋势，通过分析汽油机主要摩擦副的摩擦磨损特性和润滑状态以及汽油机对润滑油的性能要求，在润滑理论的指导下和参阅大量资料的基础上，合理地选择基础油和添加剂。本文用均匀实验设计安排实验，用逐步回归技术进行结果处理，分析了基础油对添加剂的感受性和添加剂之间的配伍性。在重点考察汽油机油低温性能的基础上，提出了15w 40sh级汽油机油的优化配方。
