Production process of building wall composite material

The invention discloses a production process of a building wall composite material. The production process comprises the following steps: (1) pretreating attapulgite; (2) modifying attapulgite; (3) preparing a pre gel solution; (4) preparing modified wheat-straw fibers; (5) mixing the modified attapulgite and the modified wheat-straw fibers, and adding calcined kaolin, modified talcum powder, quartz sand and cement to obtain a mixture A; (6) adding a lubricant and water into the mixture A to obtain a mixture B; (7) adding an epoxy resin emulsion and an organosilicon emulsion into the mixture B, then adding methyl cellulose ether and triethanolamine, and then evenly stirring and mixing the mixture to obtain a mixed slurry material; (8) placing the slurry material in a mold to perform pressure molding to obtain a preform; and (9) performing maintenance on the preform to obtain the building wall composite material. The building wall composite material prepared by the production process has different hybrid syner
