Graphite modified water-coated anticorrosive resin and preparation method

Abstract

The invention discloses graphite modified water-coated anticorrosive resin and a preparation method. The graphite modified water-coated anticorrosive resin is prepared from the following components inpercentage by weight: 5 to 10 percent of graphene dispersion liquid, 30 to 38 percent of deionized water, 26 to 33 percent of vegetable oil fatty acid, 9 to 15 percent of pentaerythritol, 9.5 to 16 percent of phthalic anhydride, 0.03 to 0.1 percent of an antioxidant, 2 to 3.62 percent of an emulsifier and 0.3 to 0.47 percent of a pH modifier. The sum of the weight percent of all the components inthe modified water-coated anticorrosive resin is 100 percent. The anticorrosive coating for a steel structure synthesized by the anticorrosive resin disclosed by the invention has the advantages of better water resistance, weather resistance, stable performance and higher paint film hardness; the graphite modified water-coated anticorrosive resin is anticorrosive resin with excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of water-based anticorrosion coatings, and in particular relates to a graphene-modified water-coated anticorrosion resin and a preparation method thereof. Background technique [0002] Traditional solvent-based coatings emit a large amount of VOCs into the air during the synthesis and construction process, which is one of the main sources of air pollution, ranking second only to automobile exhaust. With the impact of the oil energy crisis and the enhancement of people's awareness of environmental protection, the paint industry has gradually turned to the direction of saving resources and energy, reducing pollution, benefiting ecological balance and improving economic benefits. At present, the technological development of the coatings industry is mainly reflected in "water-based, powderized, and high-solidification", and solvent-based coatings with a solid content of less than 50% are technologies in decline.

Problems solved by technology

[0004] However, water-based alkyd resin coatings have many performance defects, such as slow drying of the paint film, low hardness, corrosion resistance, poor outdoor weather resistance, and poor hydrolysis resistance due to a large amount of ester bonds.

However, the modification of water-based alkyd resin by existing technologies such as acrylic acid, styrene, polyurethane, epoxy resin, silicone, and inorganic nanometers can only solve part of the problem.
