NOVELTY - Shoe midsole paperboard with moisture absorption and heat absorption function comprises 100 pts. wt. yellow core cardboard, 90-110 pts. wt. milk box paper, 90-110 pts. wt. soft-leaf bleached pulp, 5-10 pts. wt. sodium polyacrylate, and 0.05-0.1 pts. wt. graphene as papermaking slurry, and is prepared by papermaking process comprising e.g. (a) adding the yellow core paperboard and milk box paper into the pulping machine, crushing to obtain the fiber slurry; (b) pumping the fiber slurry obtained in the step (a) into a high-concentration slag remover for the first purification; (c) pumping the fiber slurry purified in the step (b) into a fiber separating machine to defibrate the fiber for the first time; (d) pumping the fiber slurry after the first fiber thinning in the step (c) into the pressure sieve for the second time purification, and concentrating the fiber slurry by the inclined net; and (e) pumping the second purified and concentrated fiber slurry into the mixed slurry tank. USE - Used as a shoe midsole paperboard with moisture absorption and heat absorption function. ADVANTAGE - The shoe midsole paperboard: has simple manufacturing technique; can be realized on the traditional papermaking production line; and is good for popularization. DETAILED DESCRIPTION - Shoe midsole paperboard with moisture absorption and heat absorption function comprises 100 pts. wt. yellow core cardboard, 90-110 pts. wt. milk box paper, 90-110 pts. wt. soft-leaf bleached pulp, 5-10 pts. wt. sodium polyacrylate, and 0.05-0.1 pts. wt. graphene as papermaking slurry, and is prepared by papermaking process comprising (a) adding the yellow core paperboard and milk box paper into the pulping machine, crushing to obtain the fiber slurry; (b) pumping the fiber slurry obtained in the step (a) into a high-concentration slag remover for the first purification; (c) pumping the fiber slurry purified in the step (b) into a fiber separating machine to defibrate the fiber for the first time; (d) pumping the fiber slurry after the first fiber thinning in the step (c) into the pressure sieve for the second time purification, and then concentrating the fiber slurry by the inclined net; (e) pumping the second purified and concentrated fiber slurry into the mixed slurry tank in the step (d), then adding the needle bleached pulp after crushing by pulping machine, stirring uniformly to obtain the mixed slurry; (f) dispersing the sodium polyacrylate and the graphene in the water; pumping the mixed slurry obtained in step (e) into the disc grinder; after pulping, pumping into the slurry preparing tank, then adding sodium polyacrylate and graphene dispersed in water; then adding water to adjust the slurry concentration; preparing the papermaking slurry; (g) pumping the papermaking slurry into the headbox, dehydrating by the headbox into the conveying net, after vacuum pressing treatment, forming wet paper; (h) applying glue to the wet paper formed after pressing in the step (g) for the first time dipping treatment; squeezing and extruding multiple glue, controlling the amount of glue, then drying by the first section of drying cylinder; controlling the water content of the middle sole paperboard of 2.5 plus minus 0.5%; in this step, the raw material components of the used glue water according to mass percentage comprises: 45-55 wt.% carboxy butyl benzene latex, 5-10 wt.% xylitol, and water (balance); when preparing, adding the xylitol into the water, preparing xylitol solution, then adding the xylitol solution into the carboxy butyl benzene latex, stirring uniformly; (i) applying glue, carrying out the second dipping treatment, then drying again by the second section of drying cylinder, controlling the drying cylinder, the middle sole paper water is 6 plus minus 1%; in this step, the raw material components of the used glue water according to mass percentage comprises: 5-7 wt.% carboxy butyl benzene latex, and xylitol saturated solution (balance); when preparing, the xylitol is added into the water to obtain the xylitol saturated solution, then adding the carboxy butyl benzene latex into the xylitol saturated solution, stirring uniformly; and (j) entering a calender to press light, and then printing the needed pattern through a printer; and (k) cutting by paper cutting machine, packing to obtain the product.
