Description
Technical field
The present invention relates to C10M lubricating composition in IPC classification, in particular for zinc-plated biodegradable of cold-rolling of steel plate
Finishing liquid.
Background technology
Steel and iron industry heat zinc coating plate production technology develops quickly, including post processing engineering CGL of steel plate rolling, hot dip
Zinc product uses extensively in automobile, field of household appliances, and surface quality matches in excellence or beauty with cold-reduced sheet and electrolytic galvanized sheet, and China is raw at heat zinc coating plate
Produce and become the first in the world big producing country in yield.When producing heat zinc coating plate, owing to zinc liquid composition, air knife or cooling blower control
Improper, belt steel surface produces the coating moire of some whites sometimes, and this defect makes plate face seem relatively to spend, directly affect plating
The surface quality of zine plate, uses suitable finishing process can effectively alleviate the defect of " coating moire ".
Skin Pass Rolling of Hot-dipped Galvanized Sheet Steel major function: 1, eliminate the yield point elongation of mild steel or make yield point elongation inconspicuous, from
And prevent galvanized sheet from adding in drawing subsequently or deep-draw and man-hour skid wire occurs；2, improve plate shape, improve steel plate flatness；3, energy
There is provided certain roughness for heat zinc coating plate surface, on the one hand can improve punching performance, on the other hand can improve the attachment of paint film
Power and surface smoothness.
Published patent documentation is such as:
Chinese patent application 201410485145.5 Xiaogan City Jiang Yan Chemical Co., Ltd. is open relates to a kind of heat zinc coating plate
With finishing liquid and preparation method thereof, it is made up of following components in parts by weight: component one: water 23～33 parts, binary acid 5～8 parts, three
Unit's carboxylic acid 8～12 parts, triethanolamine 54～57 parts；Component two: water 47～68 parts, sodium carbonate 4～8 parts, potassium hydroxide 3～5 parts,
Disodiumedetate 2～4 parts, metasilicate pentahydrate sodium 6～10 parts, reverse embedding disconnected polyethers 8～12 parts, neodecanoic acid 6～8 parts,
Sodium benzoate 3～6 parts.In this formula, containing triethanolamine, sodium benzoate and KOH etc. are toxic to health and are difficult to biological fall
The material solved.
Finishing liquid mostly is single use at present, and producing substantial amounts of waste liquid needs to process, and brings harm to environment, also gives steel
Factory adds a lot of processing cost.
In order to solve the problems referred to above, some enterprises have carried out corresponding research, such as:
Chinese patent application 201020118215.0 discloses a kind of galvanized wire finishing liquid filtration cycle and utilizes device, including
Finishing liquid collection box, finishing liquid work box, filter, paper tape filter, connecing liquid bath and shower nozzle, operation roll of mill both sides set respectively
Finishing liquid shower nozzle and high-pressure water nozzle, finishing liquid shower nozzle and high-pressure water nozzle is had to be connected with finishing liquid work box respectively, water under high pressure
Pipeline between shower nozzle and finishing liquid work box is provided with high pressure water washing pump, paper tape filter and filter, and finishing liquid works
Case outlet side is provided with finishing liquid high-capacity pump, and finishing liquid work box is connected with finishing liquid collection box, finishing liquid collection box outlet side
It is provided with fluid infusion pump, is provided with below working roll and connects liquid bath, connect liquid bath and be connected with finishing liquid collection box below.
These technology are still not directed to the waste liquor contamination harm problem of product.
Summary of the invention
It is an object of the invention to provide a kind of biodegradable finishing liquid zinc-plated for cold-rolling of steel plate, be not only able to meet
The processing characteristicies such as what client needed typically lubricates, antirust, cleaning, and can be with biodegradation, the post processing for steel mill is saved
Cost, and protect environment.
The purpose of the present invention will be realized by techniques below measure: formula is:
Deionized water: 88-92%
Fatty acid amide: 5-10%
Plant type oleic acid: 2-5%
Modified block copolyether: 0.2-0.6%
Wherein, fatty acid amide is anion and nonionic surfactant, and modified block copolyether is that non-ionic surface is lived
Property agent；Fatty acid amide, plant type oleic acid and modified block copolyether all can be with biodegradations.
Especially, fatty acid amide has outstanding rustless property and emulsifying cleansing power, and can be with biodegradation；Plant
Type oleic acid nonhazardous, has rust-preventing characteristic and lubricity, can be with biodegradation；Modified block copolyether, very small amount is added just can be effective
Improve the infiltration of product, emulsifying and cleansing power, the impurity such as iron powder are had outstanding settling property, it is ensured that steel plate after cleaning
Surface smoothness；The raw material more than selected is Organic Ingredients, with biodegradation, and can not contain the toxicants such as phenyl ring class.
Advantages of the present invention and effect: have excellent moistening, cleaning, have preferable rust-proof effect, nontoxic, there is biological fall
Solve function, energy-conserving and environment-protective, safe and reliable and corrosion-resistant, there is insulating properties, product is stable and hard water resistance, zinc-plated after finishing
Plate surface cleaning is smooth, can effectively eliminate or alleviate finishing fleck defect, almost without coating cloud pattern defects.Range is more
Extensively, there is certain anti-corrosive antibacterial effect, be suitable for the area water quality is hard and use.
