Abstract

The invention discloses a rigid anti-stripping graphene water-based paint, which is prepared from the following raw materials in parts by weight: 25 to 30 parts of aluminum isopropoxide, 100 to 120 parts of epoxy resin E44, 1 to 2 parts of dodecenylsuccinic acid, 0.7 to 1 part of sodium myrastate, 0.1 to 0.2 part of octyl isothiazolinone, 0.8 to 1 part of diisopropylethanolamine, 0.06 to 0.1 part of diaminodiphenyl ether, 4 to 5 parts of mannitol, 10 to 14 parts of rigid silane emulsion, and 10 to 14 parts of graphene. According to the rigid anti-stripping graphene water-based paint provided by the invention, sodium myrastate and a sol are added, so that the viscosity of the paint is effectively improved, the adhesive force of a finished product film and a base material is improved, and the anti-stripping strength is improved; meanwhile, the graphene, aluminum-magnesium silicate and the like are added, so that the surface rigidity of the film can be effectively improved, and the shock strength is improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a hard anti-stripping graphene water-based coating and a preparation method thereof. Background technique [0002] Compared with solvent-based coatings, water-based coatings have many advantages, such as low VOC content, low odor, non-flammable, safe to use, and can be cleaned with water. Therefore, people carry out water-based treatment of epoxy resin to make it a water-based paint to meet higher requirements. Decades of research and development and application practice have proved that water-based epoxy paint inherits many advantages of epoxy resin, such as excellent adhesion to steel and cement, low shrinkage, and good resistance to medium acids, alkalis and other solvents. Corrosion and penetration resistance, good miscibility with various resins, fillers and additives, formulated into a series of commonly used anti-corrosion paints, can form a water-based epoxy anti-corrosion coatin...
