NOVELTY - Preparing production assembly type environment-friendly energy-saving insulating plate based on urban solid waste garbage involves putting the silk fiber in the urea solution for degumming treatment, then washing, drying, and placing in the calcium chloride solution to dissolve, at last, dialyzing and purifying 65-70 hours dialysis bag, the solution after dialysis uses de-ionized water to dilute to the concentration ofthe silk fibroin is 1.3-1.5 wt.%. The graphene oxide dispersion liquid is added into the silk fibroin solution, stirred, and mixed uniformly to obtain the mixed solution. The polyacrylamide is dissolved in N, N' dimethyl acetamide, stirred until the solid is dissolved, then cellulose acetate is added, continuously stirred to obtain cellulose acetate/polyacrylamide solution, the solution is taken as sheath solution, the water is taken as core solution, the coaxial spinning method is used to obtain hollow cellulose acetate/polyacrylamide fiber. USE - Method for preparing production assembly type environment-friendly energy-saving insulating plate based on urban solid waste garbage. ADVANTAGE - The method further modifies the polymer for reusing after pre-processing the solid waste garbage which saves the preparation cost of the insulating plate. DETAILED DESCRIPTION - Preparing production assembly type environment-friendly energy-saving insulating plate based on urban solid waste garbage involves putting the silk fiber in the urea solution for degumming treatment, then washing, drying, and placing in the calcium chloride solution to dissolve, at last, dialyzing and purifying 65-70 hours dialysis bag, the solution after dialysis uses de-ionized water to dilute to the concentration ofthe silk fibroin is 1.3-1.5 wt.%. The graphene oxide dispersion liquid is added into the silk fibroin solution, stirred, and mixed uniformly to obtain the mixed solution. The polyacrylamide is dissolved in N, N' dimethyl acetamide, stirred until the solid is dissolved, then cellulose acetate is added, continuously stirred to obtain cellulose acetate/polyacrylamide solution, the solution is taken as sheath solution, the water is taken as core solution, the coaxial spinning method is used to obtain hollow cellulose acetate/polyacrylamide fiber, at last, the collected fiber is placed in water, stirred to remove N, N ' dimethyl acetamide, then dried for 10-15 hours at (-)20 plus minus 2 degrees C, then dried for 1-2 days at (-)50 plus minus 2 degrees C, to obtain the hollow cellulose acetate/polyacrylamide aerogel fiber. The prepared hollow cellulose acetate/polyacrylamide aerogel fiber is placed in the mixed solution, the ultrasonic treatment is performed at normal temperature, then frozen and dried at (-)50 degrees C for 1-2 days to obtain cellulose acetate/polyacrylamide/silk fibroin/graphene oxide composite aerogel fiber. The cement, fly ash, polypropylene fiber, polystyrene foam particles, cellulose acetate/polyacrylamide/silk fibroin/graphene oxide composite aerogel fiber, de-ionized water are mixed, then the polymer-modified solid waste particles are added, stirred uniformly, the plant protein foaming agent, sodium carboxymethyl cellulose, calcium stearate are added, stirred and mixed, the prepared slurry is poured into the mold, the constant temperature is maintained for 1 day at 20 degrees C, finally demolding, continuously naturally maintained and processed for 7 days in the air to obtain the insulating plate.
