NOVELTY - High-strength shell and high-strength shell sheet and strength enhancement method involves adding 0.1-50 pts. wt. polyether polyol to the reaction device, heating to 80-120 degrees C and keeping for 1-4 hours, and then lowering the temperature to 30-40 degrees C, adding 0.1-10 pts. wt. graphene or graphene derivatives, 1-40 pts. wt. filler, and 0.1-5 pts. wt. dispersant to the polyether polyol and dispersing for 2-4 hours to form a uniform and stable mixed solution J, and heating the mixed solution C to 60-90 degrees C, adding 20-70 pts. wt. isocyanate to the mixed solution J, keeping the temperature at 60-100 degrees C, stirring for 1-6 hours to obtain component I, where the stirring speed is 1-500rpm, adding 0.1-20 pts. wt. graphene or graphene derivatives, 0.1-40 pts. wt. filler. USE - High-strength shell and high-strength shell sheet and strength enhancement method. ADVANTAGE - The high-strength shell and high-strength shell sheet and strength enhancement method has high intensity. DETAILED DESCRIPTION - High-strength shell and high-strength shell sheet and strength enhancement method involves adding 0.1-50 pts. wt. polyether polyol to the reaction device, heating to 80-120 degrees C and keeping for 1-4 hours, and then lowering the temperature to 30-40 degrees C, adding 0.1-10 pts. wt. graphene or graphene derivatives, 1-40 pts. wt. filler, and 0.1-5 pts. wt. dispersant to the polyether polyol and dispersing for 2-4 hours to form a uniform and stable mixed solution J, and heating the mixed solution C to 60-90 degrees C, adding 20-70 pts. wt. isocyanate to the mixed solution J, keeping the temperature at 60-100 degrees C, stirring for 1-6 hours to obtain component I, where the stirring speed is 1-500rpm, adding 0.1-20 pts. wt. graphene or graphene derivatives, 0.1-40 pts. wt. filler, 0.1-15 pts. wt. nano materials, 0.1-10 pts. wt. dispersant and 20-70 pts. wt. amino-terminated polyether to the reaction kettle, stirring at room temperature for 2-4 hours to obtain mixed solution L, where the stirring speed is 300-1500rpm, adding the mixed solution L to the grinding equipment and grinding for 2-10 hours, adding the ground mixed solution L into the reaction kettle, adding 0.5-20 pts. wt. pigment and 10-40 pts. wt. chain extender into the reaction kettle, vacuumizing and stirring at room temperature for 0.5-2 hours to obtain K component, where the stirring speed is 300-1500rpm. The nano material is zirconium oxide, silicon dioxide, zirconium diboride, titanium aluminum carbide, yttrium oxide, yttrium oxide, cerium oxide, and silver powder, placed the I component and the K component into the L container and the M container with a volume ratio of 1:1, placed 0.5-80 pts. wt. antibacterial disinfection particles into N container for use, placed 0.5-80 pts. wt. photosensitive glue into the O container for later use to obtain product.
