聚氨酯型吸水膨胀橡胶的制备及性能研究
Study on preparation and properties of water swelling rubber modified by polyurethane
摘要
Abstract
The water swelling rubbers modified by polyurethane were prepared by the nitrile rubber,super absorbent polymer(SAP),polyethylene glycol(PEG)and Isophorone diisocya-nate(IPDI)which were mixed by two-roll mill machine.The influlence of the dosage of sul-fur 、PU and SAP on the water absorbency and the tensile strength of WSR were mainly dis-cussed.At the same time,the morphology of the SAP and WSR were observed by SEM.The results show that the water absorbency of the WSR first increases and then decreases with the increase of the dosage of sulfur and PU,and it increases with the increase of the dosage of SAP.The tensile strength of the WSR first increases and then decreases with the increase of dosage of sulfur 、PU and SAP.The more optimum dosage of Sulfur 、PU and SAP is 0.5 g 、15 g and 30 g respectively.SEM shows that SAP is spherical and its surface is rough.The WSR cross section without SAP is full of small holes,while the WSR section with SAP is more compact.关键词
