Abstract

Polyurethane bentone coatings were prepared using high shear homogenizer (HSH@4000rpm, a high shear instrument), mixer (M@40rpm) along with ultrasonicator bath(USB), to visualize the impact of the processing instruments on the structure, properties, performance of polyurethane/bentone 38 coatings. We also alter the sequencing of the instruments i.e. parallel and series sequencing of USB and HSH, USB and M, tried to visualize the impact of shear of the instruments. We replaced bentone 38 with C20A and studied the effect of different organoclays on mechanical properties of PU/Clay coatings. Morphology of the coatings was studied using XRD and TEM, mechanical properties were evaluated by nanoindentation. Performance of the coatings was evaluated by flame retardancy and water absorption studies.

加工仪器会影响Bentone / PU涂层的机械性能和界面相互作用

摘要

使用高剪切均化器（HSH @ 4000rpm，高剪切仪器），混合器（M @ 40rpm）和超声浴（USB）制备聚氨酯膨润土涂料，以观察加工仪器对结构，性能和性能的影响聚氨酯/ Bentone 38涂料。我们还更改了仪器的顺序，即USB和HSH，USB和M的并行和串行顺序，试图可视化仪器剪切的影响。我们用C20A代替了膨润土38，并研究了不同有机粘土对PU /粘土涂层机械性能的影响。用XRD和TEM研究了涂层的形貌，通过纳米压痕评价了机械性能。通过阻燃性和吸水性研究评估了涂层的性能。
