Description
Technical field
The invention belongs to color-painted steel strip and produce the pretreatment technology field, relate in particular to a kind of grease-removing agent and compound method for coated steel sheet production.
Background technology
The anti-corrosion capability of color-painted steel strip excellence and decorate properties are to realize by substrate surface, obtaining the good coating of sticking power, for strengthening the sticking power of coating to substrate surface, improve the anti-corrosion capability of color-painted steel strip, before the steel plate coating, must carry out pre-treatment to surface of steel plate, pre-treatment generally includes the technological processs such as degreasing, table tune, passivation.Degreasing is most important as pretreated the first link, directly affects the effect of subsequent technique and the quality of product.Grease-removing agent is that the physical and chemical activity by chemical substance weakens or the adhesion of failure surface dirt, and makes the dirt removed dissolve, disperse or be suspended in scavenging solution, no longer is deposited on metallic surface, thereby obtains clean metallic surface.
At present, the kind of metal surface degreasing agent is a lot, as " grease-removing agent and the compound method thereof " of publication number: CN101200804A introduced the grease-removing agent on a kind of clean metal surface, its duration of efficacy is long, cost is low, and degreasing effect is good, but due to phosphorous and harmful to environment in its formula." a kind of additive for industrial agent of non-phosphate degreasing and the industrial agent of non-phosphate degreasing that contains this additive " of publication number: CN1888040A, " agent of non-phosphate degreasing " of publication number: CN101314855A, it is good that patents such as publication number: CN101358355A " additive of agent of non-phosphate degreasing and the agent of non-phosphate degreasing that contains this additive " has all highlighted deoiling effect, and without phosphorus, the grease-removing agent of environmental sound, but these grease-removing agents, for cold-reduced sheet or the preparation of other metallic surfaces, have been ignored the Special Circumstances of present color-painted steel strip production with substrate.At present color-painted steel strip production is mainly zinc-plated, hot-dip aluminizing zinc or pot galvanize aluminium steel plate with substrate; because zinc is amphoteric metal; character is active; under acid and alkalescence, all can react by corrosion; so except greasy dirt, dust and other dirts that will remove substrate surface, also want the protective coating metal itself not to be damaged by corrosion, like this corrosion resisting property of guarantee coating substrate when carrying out skimming treatment; obtain clean substrate, thereby obtain the coating that sticking power is stronger.
Produce at present color-painted steel strip grease-removing agent used and have following problem:
(1). grease-removing agent alkalescence is stronger, can corrode part zinc layer during degreasing, forms precipitation, and grease-removing agent effective ingredient density loss affects the corrosion resisting property of degreasing effect and substrate.
(2). color-painted steel strip production at present be take phosphorous grease-removing agent as main with grease-removing agent, and environment is had to certain hazardness, can increase cost and the energy consumption of wastewater treatment simultaneously.
(3). degreasing produces a large amount of foams, can take away the partially skimmed agent like this, affects degreasing effect and Working environment.
In sum, in order to reduce the destruction of color-painted steel strip production pre-treatment degreasing process to hot dip galvanizing substrate, need a kind of deoiling effect good, and can protect zinc coating not to be destroyed, steep less the grease-removing agent of environmental protection.
Summary of the invention
The purpose of this invention is to provide good, the low alkali environmental protection of a kind of degreasing effect and do not corrode substrate coating, coated steel sheet production cheaply grease-removing agent and collocation method thereof.
Technical scheme of the present invention is: a kind of coated steel sheet production grease-removing agent, comprise additive, tensio-active agent, inhibiter and water base degreased cleaning agent, it is characterized in that being formed by the raw material of following weight percent: the polyoxyethylene glycol that additive is 5%～10%, tensio-active agent is 10%～15% nonionogenic tenside, one or more of the molybdate that inhibiter is 3%～6%, silicate and Sodium Benzoate, surplus is water base degreased cleaning agent.
Nonionogenic tenside is one or both of sucrose fatty ester and alkyl glycoside.
Water base degreased cleaning agent is one or more of sodium hydroxide, sodium carbonate, Sodium Tetraborate.
Coated steel sheet production is 40～55 ℃ by grease-removing agent Applicable temperature scope.
The compound method of grease-removing agent for a kind of coated steel sheet production, is characterized in that, by after inhibiter and the mixing of water base degreased cleaning agent, adding the container for stirring that fills water, then additive and tensio-active agent added in this container.
The present invention compared with prior art, has good oil removing scrubbing effect, has protected the zinc coating of coated steel sheet production with substrate simultaneously, guarantees that its original corrosion resisting property is not destroyed, and reduces the hazardous property of grease-removing agent, reduces cost for wastewater treatment and energy consumption.
