Abstract
The invention discloses a method for preparing a degreasing agent before treatment of a metal piece nano conversion film. The prepared degreasing agent comprises alkyl glucoside, fatty acid methyl ester sulfonate, fatty alcohol polyoxyethylene ether sulfate, dodecyl fatty alcohol polyoxyethylene ether, java foundation class (JFC) penetrating agent and easily biodegradable surfactant serving as main components; and soda ash is used as an alkali auxiliary agent, a little amount of chelating agent is added, and the balance is water. Compared with the prior art, the method has the following advantages that: 1) by adopting the high biodegradable surfactant, the degreasing agent is non-toxic and easy for degradation treatment, and has no harm to the environment; 2) because phosphates such as sodium tripolyphosphate, sodium polyphosphate and the like are not contained, no phosphorus-containing wastewater is contained, subsequent wastewater treatment is not needed, and the method has no harm to the environment; 3) because silicate or metasilicate is not contained, so the degreasing agent is easy for cleaning; and 4) the degreasing agent can meet the technical requirement of surface cleanliness before the nano conversion film treatment before metal piece coating.
Description
Technical field
The present invention relates to a kind of metalwork surface-treated grease-removing agent, the grease-removing agent preparation method before particularly a kind of metalwork nanometer conversion film is handled.
Background technology
Because metalwork adopts parkerizing method to have brought harm largely for environment and health, use the Coating Pretreatment mode of environmental protection to become a kind of trend, and before the metalwork application, adopt new type of metal nanometer conversion film to handle, usually such conversion film thickness is 20-500nm, therefore the degree of cleaning to the metalwork surface have higher technical requirements, have low residual amt (0.1-0.01mg/cm only
2) just can guarantee effective combination of organic coating and metalwork matrix surface nanometer conversion film.Cleaning and degreasing agent commonly used contains organic soluble additive, tensio-active agent and inorganic base substance.The metal cleaning and degreasing agent that the degreasing of metal current spare Coating Pretreatment all adopts sodium hydroxide, silicate, phosphoric acid salt and tensio-active agent etc. to mix.Its ultimate principle is fatty acid glycerine and the alkali generation saponification in the greasy dirt on metalwork surface, and emulsifying effect, at a certain temperature, has removed the vegetable and animals oils and the mineral oil on metalwork surface, has improved the degree of cleaning on metalwork surface.But above-mentioned common metal grease-removing agent still exists overbasic sodium hydroxide, phosphoric acid salt and silicate, to metalwork meeting etched the matrix, the wastewater treatment difficulty, and with high costs, easily absorption is difficult to problems such as cleaning in the metallic surface, and the metallic surface degree of cleaning before the application are had a negative impact.Adopted sodium metasilicate to substitute phosphoric acid salt among the Chinese patent CN101381876A " non-phosphate non-nitrogen easy-to-biodegrade metal spent meal and preparation method ", this component existence easily is adsorbed on the metalwork surface and is difficult for thoroughly removing in use, and because silicate exists, do not use weak points such as easy generation jelly in the working fluid at the placement certain hour.
