Abstract
A method for preparing a deacidifying and reinforcing agent for a cellulose acetate film includes steps of: ultrasonically dispersing a nanometer alkaline oxide into an ethyl cellulose n-butanol solution, so as to form a nanometer alkaline oxide suspension, then adding a mixture of E51 epoxy resin and a curing agent thereof; wherein the nanometer alkaline oxide is a nanometer magnesium oxide, a nanometer cerium oxide, a nanometer magnesium hydroxide, a nanometer potassium carbonate, a nanometer calcium hydroxide or a nanometer barium hydroxide. A method for using the deacidifying and reinforcing agent includes steps of: evenly applying the deacidifying and reinforcing agent on a surface of a cellulose acetate film.
Claims16
A deacidifying and reinforcing agent for a cellulose acetate ester film, wherein the deacidifying and reinforcing agent is formed by ultrasonically dispersing a magnesium oxide with particle sizes of 20-50 nm into an ethyl cellulose n-butanol solution whose mass fraction is 5%-8%, so as to form a nanometer magnesium oxide suspension, then adding a mixture of E51 epoxy resin and a curing agent thereof with a mass ratio of 1:1 into the nanometer magnesium oxide suspension and thoroughly mixing;
