摘要
Abstract
Two-dimensional inorganic material boron nitride(BN)with excellent chemical stability and mechanical properties was used to modify graphene by liquid-phase ultrasonic exfoliation,and prepared boron nitride/graphene(GBN)composite fillers to prepare PVC composites.Furthermore,the effects of GBN filler content on the corrosion resistance of PVC composites were studied.The results showed that the contact angle of PVC composites was significantly improved at a GBN content of 1.0%,reaching 156°.As the GBN content increases,the weight loss rate and physical size change rate of PVC composites continuously decrease.Among them,the weight loss rate of PVC composites reaches the lowest at a dosage of 1.5%,which is 8.98% .When the size change rate exceeds 1.0%,the downward decrease tends to be gentle.In addition,when the GBN content is 1.0%,the tensile stress retention and tensile strain retention of PVC composites are 156% and 82%,respectively.The color difference of PVC composites gradually decreases,and when the GBN content exceeds 1.0%,the color difference of PVC composites tends to stabilize.When the content is 1.0%,the color difference of PVC composites is 7.8.The research provides a reference for the preparation of PVC composites with strong corrosion resistance.关键词
