The invention discloses an integrated preparation process of a multifunctional oil purifier, and relates to the technical field of oil purifier preparation, the preparation process comprises the following steps: a low-temperature primary mixing stage: pretreating a bio-based raw material, and preparing a primary nanoscale dispersion by a low-temperature dispersion technology; according to the invention, the problem of agglomeration of nanoparticles is solved through a nano-surfactant pre-assembly process in a low-temperature primary mixing stage by using a small-size effect and mild stirring, and the nanoparticles are endowed with an adsorption-catalysis-dispersion composite function through in-situ coating and synergistic assembly in a medium-temperature reaction stage, so that the oil stain decomposition and removal capability is enhanced, and the oil stain removal efficiency is improved. And in the final blending stage, through gradient particle size regulation and control, nanoparticles with different particle sizes act on a macroscopic oil film and a microscopic gap respectively, so that full-scale decontamination and precise matching of process parameters in each stage are realized, synergistic enhancement of dispersibility and functionality of the nanoparticles and product stability is ensured, storage layering is avoided, and the cleaning efficiency is remarkably improved.

The invention relates to the technical field of laundry detergents, in particular to a photocatalyst degerming and disinfecting laundry detergent and a preparation method thereof. The problems that a laundry detergent is poor in cleaning effect and easy to damage clothes are solved. According to the invention, the decontamination capability of the laundry detergent is improved by changing the dosage of the photocatalyst nano titanium dioxide and the stirring temperature and time; the whiteness maintenance of the laundry detergent on clothes is improved by changing the dosage of the first anionic surfactant and the variety and dosage of the nonionic surfactant; the softness of the laundry detergent to clothes is improved by changing the reaction temperature and time and improving the dosage of the chelating agent and the part ratio of the mixture in the chelating agent; the bactericidal ability of the laundry detergent is improved by changing the dosage of the parachlorometaxylenol, the soapberry extracting solution and the improved degerming agent; the rinse foam height of the laundry detergent is reduced by varying the amount of the second anionic surfactant and the fraction ratio of the mixture therein.
