Abstract
The present invention discloses wet smoothing liquid which contains 5 to 35% of organic acid, 5 to 35% of organic amine, 2 to 25% of corrosion inhibitor, 0.1 to 1% of surface active agent and 10 to 35% of water. The present invention uses the organic amine and the organic acid as compound antirust agents, multiple kinds of corrosion inhibitors and cleaning additives are compounded, and the present invention has good cleaning performance and antirust performance. Smoothed steel plates do not have the problems of plate surface rust corrosion and color spot generation, the quality of the steel plates is good, and the present invention has proper lubricating performance and does not have the problem of nitrite pollution.
Description
Technical field:
The present invention relates to the wet-leveling liquid that uses in a kind of smooth operation of cold-rolled steel sheet manufacturing processed.
Background technology:
As everyone knows, the manufacturing of cold-rolled steel sheet is broadly divided into pickling, rolling, annealing, smooth and refining oiling five big operations, wherein rolling, annealing and smooth be three master operations of decision cold-reduced sheet quality quality.So-called smooth operation is meant the rolling processing of carrying out later at coil annealing of low deflection, and its main purpose is in order to eliminate some plate plane defect and the further mechanical property that improves steel plate that rolling technology causes.Smooth operation is divided into does smooth and wet smooth two kinds, and many at present employings are wet smooth, and present wet-leveling liquid is generally based on the inorganic wet-leveling liquid of Sodium Nitrite type, the health problem of have that cleaning is poor, plate face luminance brightness difference and " nitrite " bringing.Especially rustless property is not ideal enough, and steel plate plate face corrosion of the smooth back of ubiquity and generation color spot problem, has influenced the plate face quality of steel plate.
Summary of the invention:
The object of the present invention is to provide a kind of cleaning performance and good antirust property, the wet-leveling liquid that does not exist nitrous acid to pollute.
Technical solution of the present invention is:
A kind of wet-leveling liquid, its feature: contain following composition by weight:
Organic acid 5～35%
Organic amine 5～35%
Inhibiter 2～25%
Tensio-active agent 0.1～1%
Water 10～35%.
Organic acid is C
6～C
14Straight chain diprotic acid or C
8～C
12Lipid acid, p-tert-butyl benzoic acid, p-nitrobenzoic acid, triazines multi-carboxylic acid compounds, ε-different nonanoyl amino acid derivative.Organic amine is Monoethanolamine MEA BASF or diethanolamine, trolamine, a Yi Bingchunan, diisopropanolamine (DIPA), tri-isopropanolamine, morpholine, N-methylmorpholine, N-ethylmorpholine, 2-amino-2-methyl-1-propanol, diethylaminoethanol.Inhibiter is Sodium Benzoate or Sodium orthomolybdate, amine molybdate, urotropine, sodium salicylate, Methylbenzotriazole, benzotriazole, mercaptobenzothiazole, triazole.Tensio-active agent is aliphatic alcohol polyethenoxy (5～12) ether or Nonyl pheno (5～12) ether, aliphatic alcohol polyethenoxy polyethenoxy ether.
The present invention adopts organic amine and organic acid as the composite antirust agent, and composite multiple inhibiter and cleaning additive, have good cleaning and good anti-rust properties, there is not the corrosion of plate face in steel plate after smooth and produces the color spot problem, plate quality is good, and have suitable lubricity, do not have the nitrite pollution problem.
