Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0024] This invention provides a secondary bathroom cleaning agent, which can be used directly for bathroom cleaning or as a secondary cleaning after a primary bathroom cleaning. For example, it can be used instead of commercially available cleaning agents for bathroom cleaning. Commercially available bathroom cleaning agents often have poor cleaning power, require considerable effort, and easily leave residues, leading to corrosion and other damage to sanitary ware. By using the secondary bathroom cleaning agent of this embodiment for secondary cleaning, it can further remove any remaining dirt and grime, and also remove any residues left after the primary cleaning, thus better protecting sanitary ware. The secondary bathroom cleaning agent and its preparation method are described in detail below.

Specifically, the initiator can be, for example, azobisisobutyronitrile (AIB).

[0031] In the above preparation process, diallylmethylalkylammonium bromide and methacrylic acid are used as the main raw materials, and N,N-dimethyl(meth)acrylamide is used as a crosslinking agent to polymerize and obtain a multi-component copolymer. In particular, when the bathroom secondary cleaner in this embodiment is used for secondary cleaning, the polymer can penetrate into the surface to be cleaned and combine with the residual surfactant, which helps to form hydrophilicity on the surface to be cleaned, thereby making it easier to wash away stains and cleaning agent residues.

[0032] Specifically, in one embodiment, the propoxy compound is: in a mass ratio of 1:1 The mixture consists of two components. Both components are propoxylated products of ethylene glycol, which can be obtained through the polymerization reaction of ethylene glycol and propylene oxide. The addition of these propoxy compounds improves the cleaning ability against rust and corrosion.

Specifically, the pre-treatment process includes: quick-freezing air-dried hibiscus flowers and pedicels in liquid nitrogen to obtain freeze-dried material; subjecting the freeze-dried material to steam explosion treatment to obtain the pre-treated product. The steam explosion pressure is 0.5–1.5 MPa, the pressure holding time is 2–10 min, and the explosion process lasts 0.1–1 s. In this step, quick-freezing followed by steam explosion treatment can break down the internal fibrous tissue structure, facilitating subsequent extraction processes and effectively increasing the content of active ingredients in the extract. Furthermore, during the steam explosion process, some cellulose or hemicellulose can be hydrolyzed to generate products such as acids, aldehydes, and esters.

[0036] S12, the pretreated product is placed in an 80wt% ethanol aqueous solution and subjected to ultrasonic extraction, followed by filtration to obtain filtrate and filter residue. Specifically, the ultrasonic extraction time is 12–48 h.

[0037] S13, the filter residue is ground to obtain fine residue. The filtrate, the fine residue, and the emulsifier are then mixed by high-speed shearing in a high-speed shear mill to obtain a mixed product. Specifically, the grinding can be carried out by a high-energy nano-impact mill. Preferably, the fine residue is ground until it passes through a 200-300 mesh sieve. For example, Triton X-100 can be used as the emulsifier.

[0038] S14, the mixed product is spray-dried to obtain roselle powder.

[0039] The filtrate from the flowers and pedicels (the rod-like structure between the base of the flower and the stem) of hibiscus (Hibiscus sabdariffa Linn.) contains various organic acids and other components, while the residue is a solid component. A hibiscus powder, obtained by mixing the filtrate, residue, and emulsifier, can effectively clean various stains using the active ingredients in the filtrate. The residue acts as an abrasive, making dirt and grime easier to remove, achieving good cleaning results without vigorous scrubbing. Furthermore, the extract is gentle and will not corrode the surfaces of sanitary ware.

[0040] In addition, when hibiscus powder is mixed with component B, the hydrophilic groups in component B modify the polymer to coat the solid components in the hibiscus powder, which can improve the cleaning ability and prevent damage to the surface of sanitary products.

[0041] Further, in one embodiment, material A further includes Sichuan pepper leaf powder, and the mass ratio of the roselle powder to the Sichuan pepper leaf powder is 5-10:2. Specifically, the Sichuan pepper leaf powder is obtained according to the following steps: obtaining the filter residue generated during the extraction of Sichuan pepper leaves, grinding and drying it to obtain Sichuan pepper leaf powder. Specifically, grinding can be carried out by a high-energy nano-impact mill, preferably grinding until the particle size of the fine residue is sieved through a 200-300 mesh sieve. By adding Sichuan pepper leaf powder, the cleaning effect is further improved.

[0042] Furthermore, in one embodiment, the B component further includes an additive selected from one or both of a dispersant and a preservative. Examples of dispersants include polymaleic anhydride and polyacrylic acid. Examples of preservatives include sodium benzoate and isothiazolinone. Specifically, the mass fraction of the dispersant in the B component is 0.2%–1%, and the mass fraction of the preservative in the B component is 0.2%–1%.

[0043] Furthermore, in one embodiment, the additive further includes a polysiloxane quaternary ammonium salt. The polysiloxane quaternary ammonium salt can be, for example, a commercially available product. By adding the polysiloxane quaternary ammonium salt, the product can achieve better cleaning performance and better bactericidal ability. Specifically, the mass fraction of the polysiloxane quaternary ammonium salt in component B is 0.5% to 2%.

[0044] This invention also provides a method for preparing a bathroom secondary cleaning agent as described in any of the above embodiments, comprising: adding a hydrophilic group modified polymer, a modified acrylamide polymer, glycolic acid, Sichuan pepper leaf extract, and a propoxy compound to water to obtain component B; and adding component A to component B to obtain the bathroom secondary cleaning agent.
