NOVELTY - Zirconium silicate composite ceramic roller rod comprises 95-100 pts. wt. modified zirconium silicate particle and 3-5 pts. wt. reinforced fiber, where the reinforced fiber is prepared by (i) uniformly mixing potassium persulfate, phosphorus pentoxide and concentrated sulfuric acid, adding graphite, stirring, washing with deionized water to be neutral, performing vacuum drying to obtain pre-oxidized graphite, dissolving in concentrated sulfuric acid, adding potassium permanganate, reacting, adding deionized water, allowing to stand, adding hydrogen peroxide, washing and performing vacuum drying to obtain graphene oxide, (ii) dispersing graphene oxide in deionized water, carrying out ultrasonic treatment to obtain pre-modified grapheme and (iii) dispersing pre-modified graphene in ethanol, stirring, adding heptadecafluorodecyltriethoxysilane and deionized water and reacting to obtain modified graphene, and performing ultrasonic treatment to obtain the product. USE - The zirconium silicate composite ceramic roller rod is useful in building sanitary ceramic e.g. wall, floor tile and sanitary ware, ferrite production, glass and metal annealing industry. ADVANTAGE - The ceramic roller rod: has self-mechanical performance, high self-absorption, high wear resistance, high toughness; and is not easy to crack at high temperature. DETAILED DESCRIPTION - Zirconium silicate composite ceramic roller rod comprises 95-100 pts. wt. modified zirconium silicate particle and 3-5 pts. wt. reinforced fiber, where the reinforced fiber is prepared by (i) uniformly mixing potassium persulfate, phosphorus pentoxide and concentrated sulfuric acid, adding graphite, stirring, washing with deionized water to be neutral, performing vacuum drying to obtain pre-oxidized graphite, dissolving the pre-oxidized graphite in the concentrated sulfuric acid, adding potassium permanganate, reacting, adding deionized water, allowing to stand, adding hydrogen peroxide until the reaction solution is bright yellow, washing with the deionized water to be neutral, washing with acetone and concentrated hydrochloric acid for 3 times in sequence, washing again to be neutral and performing vacuum drying to obtain graphene oxide, (ii) dispersing graphene oxide in deionized water, carrying out ultrasonic treatment, adding tetrabutyl titanate and ethanol, stirring, adding acetic acid, heating for reaction, filtering to remove filtrate and roasting a filter cake to obtain pre-modified grapheme, and (iii) dispersing pre-modified graphene in ethanol, stirring, adding heptadecafluorodecyltriethoxysilane and deionized water, adjusting the pH value of a reaction solution, reacting to obtain modified graphene, mixing and reacting carbon fiber, potassium persulfate, silver nitrate and deionized water, adding ethylenediamine, modified graphene and 1-hydroxybenzotriazole and performing ultrasonic treatment to obtain the product.
