Study on heat resistance of SBA-15 mesoporous molecular sieve/
waterborne polyurethane composites

Abstract: Waterborne polyurethane (WPU) and SBA-15 mesoporous molecular sieves with different mass
fractions were blended to obtain composite materials by blending modification. Meanwhile, the composites
were characterized by TEM, SEM, FT-IR and TG. The results showed that the heat resistance of the composite
WPU/SBA-15 was higher than that of waterborne polyurethane, and SEM analysis showed that SBA-15
mesoporous molecular sieve could be uniformly dispersed in waterborne polyurethane. However, TEM analysis
showed that SBA-15 mesoporous molecular sieves had a little agglomeration in waterborne polyurethane.
Key words: waterborne polyurethane; mesoporous molecular sieve; heat resistance; composite materials
