Abstract

The invention relates to graphene / fluorine-silicon self-crosslinking resin composite heavy-duty anti-corrosion finish paint and preparation thereof. The finish paint is prepared from the following rawmaterials in parts by weight through in-situ polymerization: 30 to 40 parts of hydroxyethyl allyl ether, 50 to 60 parts of vinyl acetate, 25 to 35 parts of undecylenic acid, 10 to 20 parts of ethylene glycol monobutyl ether, 8 to 10 parts of vinyl siloxane, 50 to 60 parts of chlorotrifluoroethylene CTFE, 4 to 20 parts of graphene oxide, 125 to 150 parts of a solvent and 5 to 6 parts of an initiator. A graphene fluorine-silicon self-crosslinking resin composite is prepared by performing in-situ polymerization on a part of free double bonds of graphene oxide and an olefin monomer, namely, dispersing graphene in a polymer monomer for monomer-monomer polymerization and monomer-graphene-monomer polymerization. The preparation process is simple; the graphene oxide is uniformly dispersed in theresin and is firmly combined with the resin; and the defect that the graphene is easy to agglomerate is avoided. After the finish paint is cured, interface strength is improved, so the corrosion resistance of the graphene paint is improved.

Description

technical field [0001] The invention belongs to the field of anti-corrosion coatings, in particular to graphene composite fluorine-silicon self-crosslinking resin heavy-duty anti-corrosion topcoat and preparation thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] With the development of marine industry, the development of offshore oil and gas, the transportation of oil and gas, and the development of petrochemical industry, the requirements for heavy-duty anti-corrosion coatings are getting higher and higher. The anti-corrosion coating has changed from general protection to new requirements such as more durable, longer-lasting, and better decoration. One of the imp...
