Study on Hygrothermal Aging of Biodegradable Coating for Sanitary Ware
摘要
Abstract
Absrtact:The aging properties of eisai biodegradable coating at 85 ℃ and 85％humidity were studied.The changing trend of melt flow rate of eisai biodegradable coating was studied at 70 ℃.The results show that the effect of moisture-heat aging on tensile strength is greater than that of elongation at break.The addition of 1％polymerized antihydrolytic agent has the best effect on moisture-heat aging retention,the tensile strength retention is above 70％,and the elongation at break retention is above 100％.Even if the addition amount is significantly reduced,the resistance to moisture-heat aging is still excellent.The smaller the change of melt mass flow rate of membrane material system,the better the retention rate of moisture and heat aging property.关键词
