Preparation method for efficient alkyd resin anti-corrosion enamel paint

Abstract

The invention discloses a preparation method for efficient alkyd resin anti-corrosion enamel paint. The method comprises the following steps: by taking dry long-oil-length alkyd resin, dry short-oil-length alkyd resin and 20(s)-O-androstane-4-terpene-17beta-acyl camptothecin as film-forming materials, and taking a mixture of p-xylene and butyl acetate at a volume ratio as a solvent, adding talcumpowder, bentonite, a dispersing agent polyethylene glycol 200, a leveling agent polyether modified dimethyl silicone polymer and a drier manganese naphthenate; and quickly stirring, thereby acquiringthe efficient alkyd resin anti-corrosion enamel paint. The enamel paint has higher corrosion resistance and ageing resistance and can be applied to the heavy corrosion protection engineering in the fields of petrochemical equipment, pipelines, offshore oil platforms, wharf facilities and ships.

Description

technical field [0001] The invention relates to the field of enamel, in particular to a preparation method of an efficient alkyd resin anticorrosion enamel. Background technique [0002] Because petrochemical equipment, pipelines, offshore oil platforms, ships and other equipment are corroded by the atmospheric environment, especially the parts of ship equipment below the waterline are prone to foaming and cracking due to long-term immersion in corrosive media such as sodium chloride. The current treatment method is to A large amount of heavy metal compounds such as lead trioxide are added to the paint formula, but these heavy metal lead plasmas are continuously precipitated in this kind of anti-corrosion coating, which seriously pollutes the ocean, river and soil environment, and has a serious impact on the global ecological environment and human body. However, since there is no suitable alternative technology at present, it is of great significance to find a suitable alter...

AI Technical Summary

Problems solved by technology

There are many hydrogen bonds in the alkyd resin macromolecule, and the intermolecular force is strong, which can cross-link with many compounds to form a film. Therefore, the alkyd resin anti-corrosion paint formulated with alkyd resin as the film-forming substance has better Corrosion resistance, permeability resistance, wear resistance and good adhesion, etc., but there are many variable factors for crosslinking with alkyd resin to form a film. At present, due to the inappropriate matching of selected monomers and alkyd resin, crosslinking The rigidity of the joint is also poor, so the corrosion resistance is not very high, and it cannot meet the needs of the actual harsh environment.
