[0041] Preparation of graphene anti-corrosion coating

[0042] A component:

[0043] (1) At room temperature, put graphene and AC foaming agent at a ratio of 10:1 into a stirring container and stir until uniform to obtain graphene mixed powder.

[0044] (2) Put a sufficient amount of graphene mixed powder and porous rubber particles into a stirring container, and stir in the airtight container at a high speed. During the stirring process, it is heated to 50°C and kept at a constant temperature until the holes of the rubber particles are filled with graphene mixed powder. , separated by a solid sieve to remove excess graphene mixed powder.

[0045](3) Add resin, solvent, and anti-sedimentation agent into the mixing vessel, stir at a high speed of 1500r / min, add rubber particles loaded with graphene mixed powder while stirring, heat the water bath to 80°C and stir for 2 hours at a constant temperature.

Abstract

The invention discloses a high-dispersion impact-resistance graphene antiseptic coating and a preparation method. The high-dispersion impact-resistance graphene antiseptic coating has the characteristics that rubber particles capable of expanding when meeting water are etched into a porous carrier through laser, then, the mixed powder of graphene and low-temperature foaming agent is carried in thehole of the porous carrier; after the mixed power is mixed with resin coating, a foaming agent generates air and pushes the graphene in the hole to be evenly dispersed in the resin coating to obtainthe impact-resistance graphene antiseptic coating. The high-dispersion impact-resistance graphene antiseptic coating has the remarkable results: in a system formed by the graphene and porous rubber particles, since hydrophilic components are contained in a rubber substrate, primary dispersion is firstly formed, and secondary dispersion is formed by air driving, so that the problem that the graphene is unevenly dispersed is indirectly solved, the antiseptic performance of the coating is improved, meanwhile, the porous rubber particles in the coating achieve an effective buffer function, and theimpact resistance of the coating is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a highly dispersed and impact-resistant graphene anticorrosion coating. Background technique [0002] Graphene is the hardest and thinnest nano-material known to mankind. It is a hexagonal honeycomb lattice planar film formed by sp2 hybridization of carbon atoms. In 2004, it was developed by Andre Geim, a professor of physics at the University of Manchester, UK It was successfully isolated from graphite for the first time. Graphene has ultra-high hardness and strength, and excellent thermal and electrical conductivity. Graphene has a Young's modulus of about 1100GPa and a fracture strength of 130GPa, which is 100 times higher than the best steel. The thermal conductivity of graphene is as high as 5000W / (m·K). It is more than 10 times higher than common metals such as gold, silver and copper. The stable lattice structure of graphene makes it have excel...
