Improved preparation method of paint applied to internal surface of oil tank

Abstract

The invention relates to an improved preparation method of a paint applied to the internal surface of an oil tank. The paint is composed of the following components in percentage by weight: 10-25 wt% of curing agent, 10-25 wt% of methyl cellulose, 15-65 wt% of silica sol, 20-45 wt% of corrosion-resistant water-based pigment and filler paste, 20-80 wt% of ammonium polyphosphate, 20-55 wt% of microparticle silicic acid, 20-40 wt% of drying agent, 50-80 wt% of solvent, 20-60 wt% of preservative, 10-30 wt% of defoamer, 2-10 wt% of water-based assistant, 30-60 wt% of deionized water, 4-10 wt% of polyoxyethylene enzyme, 10-25 wt% of barium sulfate and 1-10 wt% of hydrogenated castor oil. The paint has the advantages of favorable corrosion resistance, high temperature resistance, favorable oxidation resistance, favorable scrub resistance and the like, has an antiseptic effect inside the oil tank, and can not easily generate chemical reaction with the liquid (turpentine, methanol and the like) in the oil tank; the construction technique is implemented by pouring the paint into the oil tank, uniformly shaking and pouring out, and thus, is simple; the paint can be closely combined with the base material immediately, and can not easily shed; and the method has the advantages of simple preparation process and low cost, and can easily implement industrialized mass production.

Description

technical field [0001] The invention relates to an improved preparation method of the paint applied to the interior of the fuel tank, in particular to a preparation method of the paint applied to the interior of the fuel tank by adding polyoxyethylene enzyme, barium sulfate and hydrogenated castor oil. [0002] Background technique [0003] The phenomenon that metal is damaged by the chemical or electrochemical action of the surrounding environment medium is called metal corrosion. In industrial enterprises such as electric power, metallurgy, chemical industry, machinery, transportation, etc., a large number of metal equipment such as iron and steel, metal components and metal buried parts are used. Corrosion, severe corrosion or damage may even cause major accidents and huge economic losses. At present, metal corrosion has brought huge economic losses to countries all over the world. According to some corrosion loss data released by the United States, Japan, Canada and ot...

There are many companies producing paint in our country, and there are many kinds of paints, but they are all common products, which are far from meeting the needs of my country's steel industry and metal anticorrosion industry. Metal corrosion is a physical phenomenon that metals are destroyed by che
