▎ 摘　　要

NOVELTY - Copper slag-based gel material comprises alkali activator, heat-absorbing material, fiber, modifying additive and light absorbing agent. The alkali activator comprises alkali substance, a silicate substance, or an alkali metal salt substance. The heat-absorbing material comprises graphene, graphite, acrylic modified epoxy resin, 2,4-dihydroxybenzophenone, chromium nitrate, and titanate coupling agent. The fiber comprises fluororubber fiber, polypropylene fiber, or asbestos fiber. The modifying additive comprises silicon carbide, boron nitride, alumina, or zinc oxide, and absorbing agent comprises chromium oxide, cadmium selenide, iron sesquioxide, titanium dioxide, lead oxide, cobalt sulfide and cadmium sulfide. USE - The gel material is useful for preparing an aerated brick (claimed). ADVANTAGE - The gelled material has relatively low hydration heat and tensile compressive strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the gel material, comprising (i) mixing the copper slag powder, slag, calcium oxide, modified auxiliary agent and absorbing agent and stirring, adding alkali excitant and de-ionized water, stirring into first slurry, continuously adding sodium hydroxide, sodium bicarbonate, silicate cement and deionized water in the first slurry, uniformly stirring and allowing to stand for 15-25 minutes for foaming process to obtain second slurry; (ii) adding absorbing material in the second slurry and fiber, continuously stirring to obtain third slurry, and (iii) pouring the third slurry into the mold vibration forming to obtain blank, where the heat sink material comprises graphene, graphite, acrylic acid modified epoxy resin, 2,4-dihydroxy benzophenone, chromic nitrate and titanic acid ester coupling agent, placing the blank in the relative humidity is 50-60%, the environment temperature is 20-30 degrees C in curing for 2-3 minutes, and demolding to obtain test piece, where the test piece in a relative humidity of 80-95%, maintaining for 25-28 days in standard room temperature of 20-30 degrees C.
