Abstract: The surface treatment for the flexible urethane cellular plastic,thus improve the performance of the foam ceramal is studied. The surface of the urethane cellular is mobilized in PEI with density of 2.4 %,the urethane foam carrier can be combined with the ceramal pulp completely, PEI can not only mobilize the surface of urethane which makes the surface of urethane has hydrophilic property, but also produce gas while burning, which affects its dynamic function,since it is a kind of organic matter.The experiments show that us ing PEI with density of 2.4% to mobilize the foam can get foam ceramal product of high quality.
KeyWords: urethane, PEI, foam ceramal, mobilize
