Abstract

The invention discloses a seawater corrosion-resistant plastic coating. The seawater corrosion-resistant plastic coating comprises the following components in parts by weight: 15-25 parts of a carrier, 5-10 parts of vinyl chloride-vinyl acetate resin, 0.5-1 part of nano-sized silicon dioxide, 3-8 parts of a silane coupling agent, 1-3 parts of a fluorosilicone hydrophobic agent, 12-25 parts of organic solvents, 5-25 parts of pigments and fillers and 28-48 parts of auxiliary agents. The plastic coating disclosed by the invention uses modified acrylic resin as the carrier, and the acrylic resin is modified by adding vinyl chloride-vinyl acetate resin, nano-sized silicon dioxide, the silane coupling agent and the fluorosilicone hydrophobic agent according to different adding proportions, so that the plastic coating achieves better seawater corrosion resistance; meanwhile, the relevant auxiliary agents and the relevant organic solvents are added, so that the permeability of the coating is effectively reduced and the structure and the corrosion resistance of the coating are further enhanced, and thus the plastic coating meets the market demand on the seawater corrosion-resistant coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a seawater corrosion-resistant plastic coating. Background technique [0002] With the continuous improvement of people's living standards, traveling to the seaside has become one of the main contents of people's leisure life. In the process of people's travel, tourists want to save the most precious moment, which requires the use of cameras, mobile phones and Cameras and other shooting equipment. [0003] Seawater is a strong corrosive electrolyte solution with high salt content, strong electrical conductivity, and biological activity. Therefore, plastics are strongly corroded in seawater. The experimental results show that the average corrosion rate of plastic in seawater is 0.1-0.2mm / a, and the perforation rate is 5-7 times the average corrosion rate. Plastics are destroyed in seawater by chemical, physical and biological factors. The result of plastic corrosion: the mater...
