| titleOfInvention | A kind of preparation method of nano-silica/polyvinyl alcohol/crust liquefaction product fresh-keeping film material |
| abstract | The invention discloses a preparation method of nano-silica/polyvinyl alcohol/crust liquefaction product fresh-keeping film material, comprising the following steps: dissolving polyvinyl alcohol in deionized water to obtain a polyvinyl alcohol solution; The acid catalyst is mixed and reacted to obtain a liquefied crustacean, which is then filtered and rotary evaporated to obtain a liquefied crustacean product; the liquefied crustacean product is added to the obtained polyvinyl alcohol solution, and after stirring, nano-silicon dioxide is added, and after stirring Cooling and ultrasonic treatment to obtain a fresh-keeping film liquid; and then the film is casted and laid to solidify into a film, rinsed with an ethanol aqueous solution, and dried to obtain a fresh-keeping film material of nano-silica/polyvinyl alcohol/crust liquefaction product. In the invention, nano-silica is used as functional filler, and the liquefaction product of carapace is used as reinforcing item. Through the blending modification of the two, the prepared fresh-keeping film material has good thermal stability, mechanical properties, flexibility and fresh-keeping and biodegradation. sex. |
