Oil tank inner wall oil-resistant epoxy paint and preparation method thereof

Abstract

The present invention discloses an oil tank inner wall oil-resistant epoxy paint and a preparation method thereof, and the paint is prepared from the following raw materials by weight: E-20 epoxy resin, maleic anhydride, butyl alcohol, diatomite, nano bentonite, phenyl glycidyl ether, pigments and additives including a dispersing agent, an anti rust agent, a flame retardant agent, an initiator, a defoaming agent, an antioxidant and a solvent. The oil tank inner wall oil-resistant epoxy paint not only improves the compactness of a paint film, enhances the anti oil permeability performance of the paint film, also has the advantages of very strong acid and alkali resistance, corrosion resistance, rust resistance, flame resistance, strong adhesion, high hardness, scratch resistance, quick drying, simple preparation process, low cost and the like, is especially suitable for anticorrosion coating of oil tank inner wall of mechanical and electrical equipment and power plant equipment, and is very obvious in effect.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and specifically aims at industries such as machinery, electric power and automobiles, and provides an oil-resistant epoxy paint for the inner wall of a fuel tank and a preparation method thereof. Background technique [0002] As an important coating, epoxy paint is widely used in the coating anticorrosion process due to its good anti-corrosion performance. However, the traditional epoxy paint currently used is easy to powder and change color due to its poor oil resistance It should only be used as a primer and intermediate coat for ordinary metalwork. [0003] The fuel tank is mainly used to store petroleum oil products, such as diesel oil, gasoline and special specification oil, etc. Its main components are mixed components of different hydrocarbons—alkanes, cycloalkanes, aromatic hydrocarbons, etc., which are extremely corrosive and Solubility, traditional epoxy paints are often eas...

Problems solved by technology

Secondly, the anti-corrosion quality of the paint will directly affect the safe use of the fuel tank on the one hand, and on the other hand, it will lead to a decline in the quality of the oil product and the service life of the fuel tank equipment

According to preliminary statistics, at present, metal fuel tanks account for more than 98% of the fuel tank usage. Every year, the equipment maintenance and oil quality decline caused by the corrosion of the inner wall of the fuel tank will bring large economic losses to enterprises and society. Therefore, it is urgent to adopt technological innovation. To promote the industrial upgrading of the paint and coatings industry
