Abstract

The invention relates to a preparation device and a preparation method of a nano photocatalytic self-foaming resin cement-based material. The device comprises a stirring kettle, a material guide pipeis fixedly installed at the bottom end of the stirring kettle, a material storage box is connected to one side of the material guide pipe in an embedded mode, a submersible pump is installed on one side of the interior of the material storage box, a hose is fixedly connected to the top end of the submersible pump, the hose is in embedded connection with the other side of the material storage box,a base is connected to one side of the storage box, a supporting column is fixedly connected to the top end of the base, a bearing plate is welded to the top end of the supporting column, a lower dieis fixedly connected to the top end of the bearing plate, and an upper die is movably connected to the upper end of the lower die. According to the technology that the prepared buoyant raft is used for removing organic compound pollution in a natural water area, a foaming resin material is used for loading a nanometer photocatalyst to form a porous light material, and the material has the advantages of being light in mass, large in specific surface area, low in cost, easy to prepare, capable of being rapidly formed and suitable for various application occasions.

Description

technical field [0001] The invention relates to the technical field of preparation of cement-based materials, in particular to a preparation device and preparation method of a nano-photocatalytic self-foaming resin cement-based material. Background technique [0002] Nano-photocatalysts are the nemesis of pollutants. The mechanism of action is simply: nano-photocatalysts are excited to generate "electron-hole" pairs (a kind of high-energy particles) under the irradiation of specific wavelengths of light. After the hole acts on the surrounding water and oxygen, it has a strong oxidation-reduction ability, which can directly decompose formaldehyde, benzene and other pollutants in the air into harmless and odorless substances, and destroy the cell walls of bacteria, killing bacteria. It kills bacteria and decomposes its wire mesh bacteria, so as to achieve the purpose of eliminating air pollution. [0003] Specifically, under illumination, if the energy of the photon is greate...
