| titleOfInvention | Nano-silver-loaded anticorrosion antibacterial polycarboxylate superplasticizer and preparation method thereof |
| abstract | The invention belongs to the technical field of concrete admixtures, and discloses a nano-silver loaded antiseptic and antibacterial polycarboxylate water reducer and a preparation method thereof, wherein the water reducer comprises the following components: 0.5-2 parts of silver compound, 1-2 parts of graphene oxide, 0.1-0.3 part of 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide, 10-50 parts of polyether macromonomer, 2-10 parts of vinyl small monomer, 0.05-1 part of initiator and the balance of water. According to the invention, the silver compound, the graphene oxide and the polycarboxylate water reducer are connected through covalent bonds, so that the problem of agglomeration of nano silver and the graphene oxide is fundamentally solved, the nano silver introduced into the product has an anti-corrosion/antibacterial effect, the anti-corrosion and antibacterial capabilities of the polycarboxylate water reducer can be remarkably improved, the problem that bacteria and microorganisms are easily bred on the surface of marine or hydraulic concrete is solved, the durability of the concrete is improved, and the service life of the concrete is prolonged. |
