Study On The Microcosmic Factors Between Stability Of Release Agent And Application Effect

In this paper, the affect factors on the stability of nano-SiO2 in release agent are mainly studied. By research the interaction of lipid surfactant—PMMA—nano-SiO₂, it reveals the essence effect of lipid surfactant and solid particles to application performance of disperse system. The goal is to adjust the proportion of lipid surfactant—PMMA—nano-SiO₂ in release agent to an optimal state. Then make the release agent has better stability, that means nano-SiO₂ totally dispersed in colloid of release agent, improves the application of release agent.The study on stability of nano-SiO₂ in release agent through the interaction of lipid surfactant—PMMA—nano-SiO₂ in release agent under gravity field and centrifugal field at first. By making the orthogonal test and range analysis, then discuss size order effect of components of release agent, and obtain a better stability proportion of release agent. At last the stockpile stability of release agent, coating film solidify, peeling intensity and release percentage are discussed between the former release agent and the new. Then a kind of release agent with excellent release capability, stability and solidy is found, and optimal component and proportion of release agent will be confirmed.The stockpile stability of release agent and coating film solidify are well by experimenting; The peeling intensity of release layer (the cling strength between coating film and PET film)is tested little by using 180°peeling method; Using Visual C++ software to compile program which can account release percentage, and the release percentage is testified very small, this result can satisfy release request in heat transfer process; The result of TEM also show dispersion state and microscopic structure of release matter in coating matter, and explain the stability of release agent by microcosmic technic. With the analysis of infrared spectrum, the combination interaction of lipid surfactant—PMMA—nano-SiO₂ in release agent has been studied. Finally the interaction of lipid surfactant—PMMA—nano-SiO₂ has been theoretical analysed by the theory of soft matter and entropy theory etc.It indicates: The study on the interaction of lipid surfactant—PMMA—nano-SiO₂ in release agent, obtain a better stability release agent, improve the application effect.
