Abstract

The invention discloses a low-carbon environment-friendly anticorrosive paint which is prepared from the following raw materials in parts by weight: 25-55 parts of a composite powder, 15-30 parts of organic silicon modified polypropylene resin, 0.5-2 parts of an inorganic filler, 1-3 parts of an organic solvent, 35-45 parts of deionized water, 10-15 parts of modified attapulgite and 0.5-1 part ofa composite antibacterial agent. The invention also discloses a preparation method of the low-carbon environment-friendly anticorrosive paint. Inorganic matters such as graphene oxide, vanadium pentoxide xerogel powder and montmorillonite are used as base materials, the base materials are mixed with organic silicon modified polypropylene resin, and the other auxiliary agents are added to prepare afinished product. According to the present invention, the graphene is subjected to covalent modification, and phytic acid is grafted to the graphene, so that the corrosion ions can be effectively prevented from entering the metal surface, and slowing down of metal corrosion is realized; by selecting the raw materials, the introduction of organic matters is greatly reduced, and the low-carbon environment-friendly anticorrosive paint is environment-friendly and has excellent metal anticorrosive performance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a low-carbon environmental protection anti-corrosion coating and a preparation method thereof. Background technique [0002] Anti-corrosion coating is a medium that blocks the contact between the surrounding environment and the metal substrate, and can effectively prevent the corrosion of the metal substrate. In recent years, with the continuous strengthening of the development of marine resources, heavy-duty anti-corrosion coatings have become an important research and development direction in the coatings field. [0003] In marine and industrial harsh corrosive environments, three-layer heavy-duty anti-corrosion systems are usually used, namely primer, intermediate paint and top coat. The characteristics of each layer of paint film are different, and their functions in the system are different. The intermediate paint connects the primer Paint and topcoat, in the s...
