摘要
Abstract
Jasmine fragrance microcapsules were prepared by in-situ polymerization using formalde-hyde-melamine resin as wall material and the thermal stability was further studied. The results showed that reducing the ratio of core and shell could improve the thermal stability of microcapsule,however worsen the morphology of microcapsules. Slowing down the prepolymer dropping rate could get both good thermal stability and morphology. The optimum conditions for jasmine microcapsule with good thermal stability and morphology were defined as 1:1 of ratio of core and shell ratio,0.6 mL/min of prepolymer dropping rate. The addition of fulldose urea could decrease the free formaldehyde amount of microcapsules.关键词
