Abstract

The invention describes a kind of no nitrite, wet aqueous coating agent, this agent can be avoided rolled steel plate and steel plate galvanized to be corroded again or pollute, it comprises benzoyl alanine N-or its salt that has a kind of general formula I at least, at least a one and (or) dicarboxylic acid, at least a alkanolamine, a kind of aromatic sulphonic acid in case of necessity and hydraulicity complexing agent, all the other are water, and with the reroll working method of band steel and galvanized steel of this wet method coating agent.

Description

The no nitrite wet aqueous coating agent of steel and galvanized steel
The present invention relates to not have the wet aqueous coating agent of nitrite, this agent can make cylinder avoid corrosion and pollution, be applicable to reroll (application) steel plate and steel plate galvanized, it comprises benzanilide, carboxylic acid and amine, also relate to simultaneously with said preparation reroll (application) band steel method.
In the presence of rolling latax, carry out cold rolling of strip steel, the steel plate attenuation that obtains and have rolling hardening, annealing makes it reach certain snappiness, in order to make softer steel plate reach the processing characteristics of expection, it must be rerolled, the purpose of this program is that the coarse place of former slick surface of steel plate is improved surface finish, does not cause its tension strain when storing like this.
Can prevent stain and deposition on the cylinder with the wet method coating agent, so-called refining that Here it is, it also can play enough lubrications, and a prior requirement is when rollers roll, and the aqueous solution adds can not made steel plate be corroded behind the band steel or fade.
Up to the present the wet method coating agent of Shi Yonging mainly comprises inorganic nitrite, mixes with alkanolamine usually, for example: one, two or trolamine.
WO81/00579 has described an inorganic nitrite, the phenylformic acid sodium salt, and yellow soda ash and ethylene glycol in case of necessity, what mainly play preservative activity here is Sodium Nitrite.
JP-109 780 has described the wet method coating agent, comprises a substituted benzoic acid, a primary amine and a carboxylic acid.
Learn that from JP-046 719 the wet method coating agent is an alkanolamine mixture that does not comprise Sodium Nitrite.
Described the wet method coating agent of no nitrite in JP-57 151 700 too, its main ingredient is a part ester or with the dicarboxylate of an o-alkylation amine here.
The no nitrite of describing in applicant's also inedited German patent application P39 23 283.2, the N-acylated derivatives that wet aqueous coating agent mainly comprises sarcosine also have carboxylic acid and amine in addition, and have the wet method coating agent to be used for many shortcomings of wet method application steel plate galvanized in this document.
From applicant's European patent application EP-B-163 107 and EP-B-205114, recognize that further the benzoyl alanine N-that has a kind of formula I can be used as sanitas in the aqueous solution.
Consider the prevention of environment protection and occupational illness, containing the nitrite agent is not ideal, and in this regard, because the danger that forms nitrosamine is arranged, so the mixing of nitrite and amine is crucial especially, in the course of processing, the wet method coating agent must be directed onto on the steel plate.Their meeting disperses, forming mist (aerosol formation) operator in rolling the air of frame peripheral can suck them in the lung.
Yet up to now, no nitrite solution is not considered to that also the wet band steel that rolls is had enough preservative activityes.
Describe in view of above situation, the objective of the invention is: provide one not have inferior pin hydrochlorate, wet aqueous coating agent, the preservative activity when it stores for band steel and galvanized steel and no less than containing inferior pin hydrochlorate mixture can make cylinder inviolateness or settling simultaneously.In addition, this mixture does not have physiological harm and the working method of be fit to reroll band steel and galvanized steel.
Theme of the present invention is, a wet aqueous coating agent that does not have inferior pin hydrochlorate, and the cylinder that it can prevent rolled steel plate and steel plate galvanized is again polluted and is corroded.It comprises a carboxylic acid and an amine, and its feature performance is as follows: no nitrite, wet aqueous coating agent comprise at least a formula I benzoyl alanine N-of 0.1-20wt%
