Present invention is disclosed a kind of auto parts aqueous cleaning agent and preparation method thereof, this aqueous cleaning agent cleaning temperature is low, long working life, nontoxic pollution-free, there is higher cleaning efficiency and good rust resistance and corrosion resistance ability, can more than 99% be reached to the cleaning rate of auto parts.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the process figure of embodiment of the present invention auto parts aqueous cleaning agent preparation method.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the process figure of embodiment of the present invention auto parts aqueous cleaning agent preparation method; This aqueous cleaning agent comprises following component by weight percentage: complexed surfactant 8.5 ~ 12%, composite assistant 6 ~ 10%, mixed inorganic 5 ~ 8%, solubilizing agent diethylene glycol ether 8 ~ 10%, inhibiter benzotriazole 0.25 ~ 0.4%, silicone antifoam agent 0.05 ~ 0.1%, deionized water 59.5 ~ 72.2%, described preparation method comprises the steps: a) to prepare complexed surfactant, b) take raw material mixing, c) add water mix and blend.
The auto parts aqueous cleaning agent that the present invention mentions take deionized water as solvent, and complexed surfactant is main body, is prepared from by adding composite assistant, mixed inorganic, solubilizing agent, inhibiter and defoamer.Wherein, complexed surfactant is by nonionic surface active agent alkylphenol polyoxyethylene and anionic surfactant so lauryl sulfate is composite forms, this complexed surfactant can make the HLB value of clean-out system be 12 ~ 14, and cloud point controls at 60 ~ 65 DEG C.Composite assistant by trolamine, Starso and tetrasodium ethylenediamine tetraacetate in mass ratio 5:4:1 mix; This composite assistant not only can the pH value of modification stability clean-out system, and can also improve the performance of tensio-active agent, and improve detersive power, softening of water, prevents soil redeposition, can also act synergistically with other inhibiter simultaneously, and protection piece surface is not corroded.Mixed inorganic by Sodium Fluoride and sodium-chlor in mass ratio 1:4 mix; This mixed inorganic can increase the penetrating power of clean-out system activeconstituents, improves the speed that greasy dirt departs from piece surface.Solubilizing agent diethylene glycol ether can increase the meltage of each component of clean-out system, promotes the emulsification solubilising of greasy dirt.Inhibiter benzotriazole can play good rust resistance and corrosion resistance effect.
