A kind of superhydrophobic JS waterproof coating and preparation method thereof

Abstract

The invention discloses a super hydrophobic JS waterproof coating and a preparing method thereof. The coating is prepared from component A super hydrophobic materials, component B emulsion and component C inorganic powder. The component A super hydrophobic materials are prepared from 15-25 parts of graphene, 2.5-6 parts of a water soluble cationic surfactant, 55-75 parts of a sodium silicate solution, 10-15 parts of NaOH of 10%, 25-45 parts of a silylating reagent and 8-15 parts of deionized water with the electrochemical stratification method; the component B emulsion is prepared from 35-55 parts of hard monomers, 35-55 parts of soft monomers, 2-5 parts of functional monomers, 2-10 parts of super hydrophobic materials, 1-5 parts of a film forming agent, 1-5 parts of a plasticizer, 0.8-1.5 parts of an emulsifying agent, 0.5-1 part of a dispersing agent, 0.5-1 part of a preservative, 0.05-1 part of an antifoaming agent and 0.05-0.1 part of an evocating agent; the component C inorganic powder is prepared from 25-45 parts of ordinary portland cement, 25-45 parts of fly-ash portland cement, 20-30 parts of quartz sand of 200 meshes, 10-15 parts of carbon nano-tubes and 0.5-1 part of a water reducer. When the super hydrophobic JS waterproof coating is prepared, the obtained super hydrophobic materials are added into emulsion polymerization, and the coating has the more excellent stabilities such as bonding strength, water resistance and impact resistance.

Description

technical field [0001] The patent of the invention belongs to the technical field of coatings, and in particular relates to a waterproof cement-based coating and a preparation method thereof. Background technique [0002] JS waterproof coating, "J" refers to (Ju) polymer, "S" refers to (Shui) cement, so it is a polymer cement waterproof material, which is made of polymer emulsion such as acrylate, ethylene-vinyl acetate and inorganic cement. It is a two-component, water-based architectural waterproof coating, which is suitable for roofing, kitchen and bathroom basements, pools and other architectural waterproofing projects. This kind of waterproof coating not only has the rigidity of inorganic materials, but also has the flexibility and high cohesion of polymers. It has outstanding waterproof effect, is non-toxic, non-polluting, easy to construct, and low in cost. It is favored by construction management departments and construction units. Generally welcome. At present, po...
