胶粘带抗刺穿性能测试装置的研制及测试方法的研究

Development of testing device and test method for puncture resistance of adhesive tape

研制了一套适用于胶粘带抗刺穿性能的测试装置和测试方法,对不同基材和厚度的胶粘带进行了测试研究。观察刺穿测试过程中刺穿力的变化,讨论了刺穿速率和刺锥头粗糙度对刺穿性能的影响,并对测试方法的稳定性和一致性进行了分析。研究结果表明:抗刺穿测试过程中刺穿负荷和形变与刺穿时间呈线性关系;随着刺穿速率的增加,刺穿力呈现下降的趋势,刺穿力的测试数据波动性增大;一般测试方法中,采用50 mm/min为默认的刺穿速率;刺锥头粗糙度增加使得刺穿力降低,粗糙度控制在0.8μm以下对刺穿力的影响可忽略不计;不同测试实验室间的测试结果重现性较好。另外,由于所研制的测试方法准确度和精度较高,可适用于不同基材制成的胶粘带的抗刺穿性能的测定。测试方法所使用的设备和治具简单,投资成本低,使用方便,能够在胶粘带厂家中推广应用,未来也可以在一些胶粘带的产品标准中予以引用。

A set of test device and test method applicable to the puncture resistance of adhesive tape were developed,and the test research was carried out on adhesive tape with different substrates and thicknesses.The change of puncture force during the puncture test was observed,the influence of puncture rate and roughness of the puncture cone head on the puncture performance was discussed,and the stability and consistency of the test method were analyzed.The research results showed that the puncture load and deformation during the puncture resistance test were linearly related to the puncture time.With the increase of the puncture rate,the puncture force showed a decreasing trend and the fluctuation of test data of puncture force increased.In general test method,the default puncture rate was adopted as 50 mm/min.The increase of roughness of puncture cone head reduced the puncture force,and the effect of the roughness controlled at less than 0.8μm on the puncture force could be negligible.The reproducibility of test results between different test laboratories was relatively good.In addition,due to the high accuracy and precision of the developed test method,it could be applicable for the determination of puncture resistance of adhesive tape made of different substrates.The equipment and fixtures used in the test method were simple,with low investment cost and convenient use,which could be promoted and applied in adhesive tape manufacturers,and could also be referenced in some adhesive tape product standards in the future.
