Abstract

The invention relates to a high-performance anti-corrosion composite coating material, which is prepared from the following components in parts by weight: 30 to 45 parts of a fluororesin monomer, 30 to 45 parts of a styrene monomer, 10 to 40 parts of a hexamethylcyclotrisiloxane monomer, 4 to 8 parts of polyethylene glycol octylphenol ether, 4 to 6 parts of polyethylene glycol, 3 to 8 parts of polyethylene glycol stearate, 20 to 30 parts of water glass 100 to 150 parts of fly ash, 2 to 4 parts of an initiator, 100 to 200 parts of water, 1 to 3 parts of defoaming powder, 5 to 10 parts of sericite powder, 0.2 to 0.5 part of a water reducing agent, 5 to 8 parts of a dispersing agent and 3 to 7 parts of a flatting agent. The invention further discloses a preparation method of the high-performance and high-corrosion-resistance composite coating material. According to the invention, a durability-improved modified fluororesin emulsion is synthesized and prepared in an efficient and environment-friendly mode, and the composite coating obtained after the modified fluororesin and the alkali-activated fly ash are fully mixed and stirred can effectively improve the compressive strength, tensile strength, low permeability, alkali resistance and good corrosion resistance of concrete.

Description

technical field [0001] The invention relates to an anti-corrosion coating and a preparation method thereof, in particular to a high-performance anti-corrosion composite coating and a preparation method thereof. Background technique [0002] In the building structure, its durability is often threatened by corrosion, which reduces the service life of the building and causes serious losses. Therefore, the corrosion protection of structures has attracted more and more attention. The anti-corrosion measures for structures mainly include body modification and surface coating technology. There are problems such as high cost and environmental pollution in bulk modification, but the surface coating is easy to operate and the anti-corrosion effect is effective and accurate. Therefore, anti-corrosion coating plays an indispensable role in the durability of concrete. [0003] Anti-corrosion coatings are mainly divided into organic anti-corrosion coatings and inorganic anti-corrosion co...
