Description

A kind of preparation method who applies to fuel tank internal topcoating
Technical field
The present invention relates to a kind of preparation method who applies to fuel tank internal topcoating.
Background technology
Metal is subject to the chemistry of surrounding environment medium or electrochemical action and the phenomenon damaged is called metallic corrosion.Use in a large number the hardwares such as iron and steel, hardware and metal to bury part in industrial enterprises such as electric power, metallurgy, chemical industry, machinery, communications and transportation, these equipment and member are under the effect of the media such as the oxygen around it, water, electrolyte ion, there is burn into heavy corrosion or damage with accumulating over a long period, even cause a serious accident and tremendous economic loss.At present, corrosion of metal has brought huge financial loss to countries in the world, some corrosion loss data of announcing according to states such as the U.S., Japan, Canada, corrosion has caused a large amount of direct economic losses, and according to estimates, approximately have in the world 20% metallic substance cannot reclaim because being corroded, thereby corrosion of metal and protection question cause the generally attention of countries in the world.The financial loss that the annual metallic corrosion of China causes accounts for 4% of gross national product, and annual corrosion loss exceedes the damnous summation of fire, disaster caused by a windstorm and earthquake.For a long time, in order to reduce the loss of corrosion, people have taked a lot of measures, as the electrochemical protection method of metal, corrosive medium facture, tectum protection method etc.But general, most economical, the most practical sfgd. or coating protection up to now, anticorrosion with coat with its easy construction, economic and practical, be not subject to the constraint of device area, shape and there is the features such as certain decorative effect and be widely used.
Along with the develop rapidly of modern industry, the anticorrosion great attention that is more and more subject to all trades and professions of metallic surface, adopting paint application anticorrosion is a kind of method of not only economy but also actual effect, concerning industrial and mining enterprises, metallic corrosion has caused massive losses to be economically difficult to estimate, account for 15%~20% of global output of steel, visible, be how important to the protection of corrosion.The method that prevents metallic corrosion is a lot, and as selected anti-corrosive alloy material on use material, though the preservative activity of playing, construction costs is large, is unfavorable for protection and the science economy of nonferrous metal resource; Also have to adopt and electroplate and cathode protecting process, but cause exhaust emission, be unfavorable for environment protection.Protection practices proves, takes to paint coating protection and be the most general the most most economical method, is first easy construction, wide adaptability, be not subject to the compression of device area, form size, secondly paint protection can be combined use with other safeguard procedures, can obtain more perfect corrosion protection system.The enterprise that China produces paint is a lot, paint various in stylely, but all belong to usual production, far can not adapt to the needs of China's Iron And Steel Industry and anti-corrosion of metal industry, corrosion of metal is that metal is subject to the chemistry of surrounding medium or electrochemical action and destroyed physical chemical phenomenon.At present, varied for preventing the method that metallic surface is corroded, but a lot of method anticorrosion ability is not fine, duration of service is shorter, brings a lot of inconvenience to live and work.
Since reform and opening-up, along with rapid development of economy, China's automobile industry has had develop rapidly, has now become the large automobile production of the first in the world state.Along with automobile pollution is increasing, demand to automotive oil tank and technical requirements are also more and more higher simultaneously, as everyone knows, automotive oil tank is for depositing liquid (gasoline, diesel oil, rosin, methyl alcohol etc.) container, automotive oil tank is to be made up of metallic substance, conventionally use after the long period automotive oil tank inwall can with the liquid (gasoline of depositing, diesel oil, rosin, methyl alcohol etc.) generation chemical reaction, thereby destruction mailbox, therefore, a kind of non-corrosibility provided by the invention, high temperature resistant, the coating that applies to fuel tank internal surface of oxidation-resistance and scrub resistance is vital.It can prevent that automotive oil tank inwall and the liquid (gasoline, diesel oil, rosin, methyl alcohol etc.) of depositing from producing chemical reaction.
