摘要
将石油沥青作为填料加入聚氨酯涂料中,通过相关测试表征来探究石油沥青对聚氨酯涂料阻尼性能的影响.测试发现,随着石油沥青添加量的增加,涂料的储能模量、损耗模量以及损耗因子都呈现出先增大后减小的趋势,当石油沥青添加量为6%(质量分数,后同)时,储能模量和损耗模量得到提升,同时损耗因子的峰值达到最大为0.94.石油沥青的加入使聚氨酯涂料的力学性能也得到改善,当石油沥青添加量为6%时,拉伸强度达到7.81 MPa,是纯聚氨酯涂料的1.44倍;断裂伸长率达到535.0%,是纯聚氨酯涂料的1.28倍.
Abstract
This article introduces petroleum asphalt as filler into polyurethane coatings and explores the effect of petroleum asphalt on the damping performance of polyurethane coatings through relevant testing and characterization.Tests have found that as the amount of petroleum asphalt added increases,the storage modulus,loss modulus,and loss factor of the material show a trend of first increasing and then decreasing.When the amount of petroleum asphalt added is 6%(wt%,the same below),the storage modulus and loss modulus are improved,and the peak value of the loss factor reaches a maximum of 0.94.The addition of petroleum asphalt improves the mechanical properties of polyurethane coatings.When the amount of petroleum asphalt added is 6%,the tensile strength reaches 7.81 MPa,which is 1.44 times that of pure polyurethane coatings;the elongation at break reaches 535.0%,which is 1.28 times that of pure polyurethane coatings.
