Magnetic plastic graphene functional external wall panel and preparation method thereof

Abstract

The invention discloses a magnetic plastic graphene functional external wall panel and a preparation method thereof. The magnetic plastic graphene functional external wall panel comprises the following raw materials: magnetic powder, sodium silicate, magnetic iron oxide, magnetic aluminium oxide, nano-titanium dioxide, polydopamine, polyphosphazene, magnetic ferroferric oxide particles, 2-ethylamine phosphate, polyvinylimide, paraffin, higher fatty alcohol, ethylenediaminetetraacetic acid, glass fibers, a heat stabilizer, an adhesive, polydiallyldimethylammonium chloride, bentonite and nano-cerium oxide. According to the invention, alphalt-based carbon fibers are adopted, so that the mechanical property of the material is enhanced, and harmful gas and dust substances of the tail gas can be adsorbed and eliminated greatly; chitosan with positively charged molecules can adsorb bacteria with negative charges, so that a bactericidal function is achieved; in the aspect of the structure, fiber membrane layers with different diameters and porosity are prepared and are combined with nano-graphene among the layers, so that the porosity and the specific surface area of the adsorption membranes are improved and the effects are enhanced. By adoption of the alphalt-based carbon fibers, the mechanical property of the material is enhanced, and harmful gas and dust substances of the tail gas can be adsorbed and eliminated greatly.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a magnetic plastic graphene functional exterior wall panel material and a preparation method thereof. Background technique [0002] Magnetic plastic is a new type of polymer functional material developed in the 1970s. It is a modern science and technology field. [0003] One of the important basic materials. Magnetic plastics can be divided into structural type and composite type according to their composition. Structural magnetic plastics refer to [0004] The polymer itself has a strong magnetic magnet. This type of magnetic plastic is still in the exploratory stage, and there is still a certain distance from practicality; composite magnetic plastic refers to a magnet made of plastic or rubber as a base material. This type of magnetic Plastics have been commercialized, and the magnetic powders currently used for filling are mainly ferrite magnetic powders and rar...
