硅橡胶绝缘材料表面剥离力预测模型

Prediction model for surface peering force of silicone rubber insulation material

选用室温硫化硅橡胶作为修复材料,分别与4种基底黏合制备成剥离试样,通过构建的材料表面剥离力计算数学模型预测了材料间的剥离力理论值,同时通过剥离力测试获取了不同材料间的剥离力实验值。结果表明,所有试样中剥离力理论值与实验值的相对大小关系一致,并且单一试样的剥离力理论值与实验值的绝对偏差均在1 N以下。该数学模型计算结果能很好地反映不同材料间剥离强度的相对强弱。

Room temperature vulcanized silicone rubber was selected as the repair material,and pee-ling samples were prepared with four types of substrates.The theoretical values of peel forces between materials were predicted by constructing a mathematical model for calculating the peel force on the material surface.At the same time,experimental va-lues of peel forces between different materials were obtained through peel force test.The results indica-ted that the relative size relationship between the theoretical and experimental values of peel force in all samples was consistent,and the absolute deviation between the theoretical and experimental values of peel force for a single sample was below 1 N.The calculation results of this mathematical model could reflect the relative strength of peel strength between different materials well.
