▎ 摘 要
NOVELTY - Preparation of graphene blended natural cellulose spunbond nonwoven fabric involves adding 0.03-0.5 wt.% sodium borohydride to oxidized graphite aqueous solution, ultrasonically processing, filtering, washing with water, adding solution to slurry containing mixture of wood pulp and methyl methionine, heating at 60-80 degrees C, removing moisture in vacuum thin film evaporator, heating to 80-130 degrees C, extruding resulting product, spinning, rolling, drying and coiling. USE - Preparation of graphene blended natural cellulose spunbond nonwoven fabric (claimed). ADVANTAGE - The graphene blended natural cellulose spunbond nonwoven fabric having excellent antistatic property and thermal function is produced without affecting the environment. DETAILED DESCRIPTION - Preparation of graphene blended natural cellulose spunbond nonwoven fabric involves adding 1-10 wt.% sulfuric acid to graphite powder, stirring in an ice bath for 30 minutes, adding 1-20 wt.% potassium permanganate for 1-2 hours, adding distilled water, adding 1-10 wt.% hydrogen peroxide for 1 hour, continuously stirring to generate bubbles, filtering resulting dark green liquid to produce a filter cake, washing the filter cake with hydrochloric acid, removing sulfate ions, rinsing with distilled water, drying at 40 degrees C for 2 hours to form an oxidized graphite solid, adding distilled water to obtain an oxidized graphite aqueous solution, adding 0.03-0.5 wt.% sodium borohydride, ultrasonically processing for 30-60 minutes to form an aqueous solution containing sodium borohydride-graphene complex such that weight ratio of oxidized graphite to sodium borohydride is 1:1-1:5, filtering, washing with water 3-5 times, adding 0.11-5 wt.% resulting solution to slurry containing mixture of wood pulp chosen from long fiber wood pulp and staple wood pulp and having cellulose content of 65% or more and polymerization degree of 500-1500, and 50-78% methyl methionine, heating at 60-80 degrees C, maintaining vacuum degree to -9.33x 104 Pa, removing moisture in vacuum thin film evaporator maintained at vacuum degree of -9.39x 104 to -9.26x 104 Pa, heating to 80-130 degrees C, extruding resulting product, spinning, rolling, drying and coiling.
