A kind of preparation method that is applied to the internal surface coating of oil tank

Abstract

The invention relates to a 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 and 30-60 wt% of deionized water. 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 (gasoline) 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 a preparation method of a paint applied to the inner surface of an oil tank. Background technique [0002] 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 other countries, corrosion has caused a large number of direct economic losses, and it is estimated that about 20 % of metal materials are corroded and cannot be recovered, so the corrosion ...

Problems solved by technology

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 chemical or electrochemical effects of environmental media. chemical phenomenon

At present, there are various methods for preventing metal surfaces from being corroded, but many methods are not very effective in anti-corrosion, and the use time is short, which brings a lot of inconvenience to life and work
