Abstract
The present invention relates to a high-effect oil and rust removing agent and a preparing method thereof, which is used for treating a metal surface. The high-effect oil and rust removing agent is mainly composed of concentrated hydrochloric acid, concentrated sulfuric acid, concentrated nitric acid, phosphoric acid, trisodium phosphate, sodium silicate, hexamethylenetetramine, thiourea, sodium dodecyl benzene sulfonate, citric acid, saccharine, OP-10 and water. When the product is used, the required devices and technology are simple. Only one tank is required. No high-temperature heating operation is required, and no brush is required for brushing the metal surface. The oil and the rust can automatically fall off by only immersing the metal surface under a normal temperature. Thus, the three work procedures of oil removal, rust removal and rust prevention are combined into a whole. No environmental pollution is caused.
Description
Technical field
The invention belongs to chemical method metallic substance cleaning technique field, be specifically related to a kind of electrochemical deoiling rust remover of metallic substance.
Background technology
The rust of metallic surface is a very complicated system, and under different oxidizing conditions, its composition has very big difference.And metallic substance is before as applications such as plating, spraying plating, immersion plating, and its surface must be handled, and promptly removes its surperficial grease, impurity and rusty scale.The method of rust cleaning has two kinds substantially at present, and a kind of is mechanical means, and a kind of is chemical process, but mechanical means can not be eliminated rust fully owing to need scrape or use the metal brush wiper with cutter, and needs a lot of labor forces.So the method for chemical rust removing is than popular.
At present, a variety of chemical rust removing agent to metallic substance are arranged both at home and abroad, they all are directly to use the derivative of mineral acid or ammonia to be major ingredient, are equipped with that interpolation auxiliary materials such as tensio-active agent, inhibiter make.In China Patent No. is among the CN86107238A, disclose a kind of oil-removing rust-removing agent, it consists of: aluminium powder, sodium hydroxide, hexamethylenetetramine, polyoxyethylene aliphatic alcohol ether, oxyethane, water, phosphoric acid form according to certain ratio, though this oil-removing rust-removing agent efficient is higher, shortened the production cycle simultaneously, but because oxyethane character instability is toxic again, dangerous in the production process, to serious environment pollution, in addition, its production cost is very high.The patent No. is also to disclose a kind of rust-removing passivator among the CN1004429A, its composition is that phosphoric acid, primary zinc phosphate, oxalic acid, zinc nitrate, polyoxyethylene glycol octyl group alkyl oxide, water mix according to a certain percentage, but because ether material character instability, so the shelf time of product is short, be easy to lose efficacy.Its rust cleaning effect is not very good simultaneously." Science and Technology Daily " reported " MX-1 water-base metal rust-removing and-preventing agent " technical products of Beijing De Bei company development on August 7th, 2000.This product mainly is that metal is had rust removing function, but it need heat use under 80 ℃ condition, as just can reach the rust cleaning effect after also needing with the brush brush under the special situation, the antirust function of this product mainly is the effect that just can reach metal rust preventing after metal shows to coat new slushing oil simultaneously.
Summary of the invention
At the problem that foregoing invention produced, the objective of the invention is: it is effective to eliminate rust, and rust cleaning speed is fast, and is cheap, and safety easy to use and do not have environmental pollution is to human body with metal is non-stimulated or infringement, safe, nontoxic, no evaporable oil-removing rust-removing agent.
