▎ 摘　　要

NOVELTY - High-strength nano-gas gel building material comprises 15-35 pts. wt. polyvinyl acetate emulsion, 5-15 pts. wt. nanoscale composite gas gel, 3-6 pts. wt. sodium polyacrylate, 5-10 pts. wt. hollow glass microspheres, 1-5 pts. wt. bentonite, 1-5 pts. wt. glass fiber, 10-16 pts. wt. silica-alumina gel powder, 20-30 pts. wt. diatom mud and 60-80 pts. wt. water. USE - The building material is useful in bearing structure of building e.g. house. ADVANTAGE - The building material has good compression strength and anti-folding strength performance, and has wide market prospect. The nanoscale composite gas gel density of cross-linked network is uniformly distributed in the building material matrix, can form a multi-layer composite gel layer to have better resistance to the external force, and the nanoscale composite gel further provided with a continuous sheet layer structure formed by titanium carbide nano sheet and oxidation graphene the nano sheet, which can play the role of blocking force diffusion, so that the composite gas is gel with more excellent resistance, to efficiently improve the mechanical property of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the building material, comprising taking the raw materials, adding water, polyvinyl acetate emulsion, sodium polyacrylate and glass fiber into the stirring tank, stirring at 1000-1500 revolutions/minute for 20-50 minutes, then adding nanoscale composite gas gel, hollow glass microspheres and silica-alumina gel powder, continuing stirring for 10-30 minutes, adding bentonite and diatom mud, stirring for 30-60 minutes to obtain a jelly-type mixture, pressing the jelly-type mixture through a pressing machine, and drying, where the drying can be done by natural air drying, or curing at 100-150°C under normal pressure for 5-10 hours.
