Abstract
The invention provides a low-foam middle-cloud-point environment-friendly water base metal cleaner composition and a preparing method thereof, and belongs to the field of metal cleaners. The low-foam middle-cloud-point environment-friendly water base metal cleaner composition is composed of low-foam low-cloud-point nonionic surface active agents, low-foam anion surface active agents, triethanolamine oleic soap, triethanolamine, styrene acrylic three azole nitrogen, ethylene diamine tetraacetic acid, sodium carbonate, polyether, organosilicone, sodium hydroxide and deionized water, wherein solid-phase raw material and liquid-phase raw material are sequentially added to a reaction container according to a formulation and metering, the organosilicone and the deionized water are finally added to the reaction container, stirring is conducted for 10min to 20min under the condition of indoor temperature, and clear products with a pH value ranging from 9 to 10 are obtained. The triethanolamine oleic soap is a cloud point improving agent, good water solubility is achieved after the triethanolamine oleic soap and the triethanolamine are re-compounded according to the ratio, solubilizing ability of the low-foam low-cloud-point nonionic surface active agents is enhanced, therefore the temperature of the solution cloud point of the cleaner is improved to 45 DEG C, cleaning efficiency of the cleaner is improved, and the low-foam middle-cloud-point environment-friendly water base metal cleaner particularly suitable for high-pressure spraying cleaning is obtained.
Description
Technical field
The environment protection water-based metal cleaner composition and method of making the same of cloud point in the low bubble of the present invention, belong to the metal cleaner field.
Background technology
Common water base metal cleaning agent in the market is various in style, substantially belongs to soak and spray the height cleaned to steep clean-out system.When spray cleans, foam volume is too much and foam time is long, not only hinders the cleaning of metallic surface dirt, also easily produces the residual of clean-out system, finally affects cleaning performance.Overflowing also of high foam can affect cleaning operation on the other hand.Therefore market has proposed more and more higher requirement to requirement and the working conditions of clean-out system over-all properties.Improve the cleaning rate of metal, can be by changing cleaning condition, as pressurization sprays and suitably improves cleaning temperature and realize.The clean-out system of pressurization spray must meet low foaming requirement, and the approach that solves bubble-related issues generally is divided into two kinds: select low foaming tensio-active agent to make the clean-out system raw material and add defoamer.Nonionogenic tenside has low bubble property, but cloud point is low and poorly water-soluble causes use range limited; And defoamer is subject to the impact of froth breaking mechanism and Financial cost to cause consumption limited, therefore how to improve these two kinds of factors, be to reach low bubble characteristic and economic and practical key.Suitably improve in addition cleaning temperature and also can improve the cleaning rate of metal, but novel nonionic low-foaming surfactant cloud point temperature is generally on the low side, during normal temperature, muddiness appears in its aqueous solution, and tensio-active agent is separated out, and has lost cleanup action.If can improve the cloud point of low bubble nonionogenic tenside, both can pass through the high cleaning rate of heating hand-held, can bring into play again its low foaming characteristics and improve cleaning efficiency by the pressurization spray.
Summary of the invention
The purpose of this invention is to provide the environment protection water-based metal cleaner composition and method of making the same of cloud point in a kind of low bubble, keeping under the low bubble of clean-out system prerequisite, by promoting clean-out system use temperature to 45 ℃, improve the cleaning efficiency of its clean-out system, and obtain cloud point water base metal cleaning agent in the low bubble that a kind of particularly suitable high-pressure spraying cleans, reach the purpose of comprehensive raising metal cleaning efficiency; Simultaneously, clean-out system of the present invention has not phosphate-containing, silicate, nitrite and environmentally friendly characteristics.
The technical scheme that realizes the object of the invention is:
One, the environment protection water-based metal cleaner composition of cloud point in the low bubble of the present invention, be comprised of clean-out system, rust-preventive agent, inhibiter, sequestrant, defoamer, mineral alkali, cloud point rising agent and deionized water, and its compositing formula by mass percentage is as follows:
Clean-out system:
Low cloud point non-ionic surfactants 0.4～2.0 He of low bubble
Low bubble anion surfactant 1.2～5.0;
Rust-preventive agent:
Trolamine 10～20;
Inhibiter:
Phenylpropyl alcohol triazole 0.5～1.5;
Sequestrant:

The cloud point rising agent:
Trihydroxy ethylamine oleate soap 0.2～2.0;
Deionized water 54～80;
The pH value is 9.0～10.
The low cloud point non-ionic surfactants of described low bubble is commodity " DF-12 " 0.2～1.0 and commodity " FK-86 " 0.2～1.0, and low bubble anion surfactant is commodity " NF-10 " 0.2～2.0 and commodity " H66 " 1.2～5.0.
The mass ratio of described cloud point rising agent trihydroxy ethylamine oleate soap and rust-preventive agent trolamine is 0.2～1.0:10～15, to obtain optimal cleaning effect.
Two, in the low bubble of the present invention, the preparation method's of the environment protection water-based metal cleaner of cloud point preparation process is as follows:
(1) by the environment protection water-based metal cleaner composite formula of cloud point in above-mentioned low bubble, take respectively Solid raw materials inhibiter phenylpropyl alcohol triazole, sequestrant disodium ethylene diamine tetraacetate and sodium carbonate, mineral alkali sodium hydroxide, and join successively in reaction vessel;
(2) taking respectively liquid phase feed nonionogenic tenside, anion surfactant, rust-preventive agent trolamine, cloud point rising agent trihydroxy ethylamine oleate soap, defoamer polyethers by the formula consumption is added in above-mentioned reaction vessel successively;
(3) by the formula consumption, finally take silicone antifoam agent and deionized water and be added in said vesse;
(4) start the agitator of reaction vessel, under room temperature condition, stir 10～20min, obtain the faint yellow transparent metal cleaner product of the present invention.
The present invention's nonionogenic tenside commodity used DF-12, FK86 all belong to the tensio-active agent of the low cloud point of low bubble, and certain bubble effect that presses down is all arranged, but its intrinsic problem is that cloud point is low, even use at normal temperature, also muddy because make its aqueous solution occur higher than its cloud point temperature, the invention employing trihydroxy ethylamine oleate soap and trolamine, add with the two preferred compound proportion, makes the auxiliary trihydroxy ethylamine oleate soap of trolamine improve the cloud point of whole solution system.Because trihydroxy ethylamine oleate soap and trolamine have after composite well water-solublely and to the solubilising of DF-12, FK86, so significantly improve the cloud point of nonionogenic tenside DF-12, FK86, make the detergent solution cloud point temperature be increased to 45 ℃; And commodity NF-10, H66 are low foaming anion surfactant, there is excellent cleansing power and solubilizing effect, the phenylpropyl alcohol triazole is the reagent that a kind of excellent property can effectively suppress metallic corrosion, the EDTA-disodium, sodium carbonate is as sequestrant and have good corrosion inhibition, polyethers L61 and silicone antifoam agent 221, as defoamer, further reduce the lathering property of clean-out system.The pH value scope of low soaked Base Metal clean-out system is 9.0～10, and its alkalescence is moderate.In addition, clean-out system provided by the invention has the characteristics such as raw material is easy to get, simple to operate, cost is lower, environmental friendliness.
