Description

Technical Field

[0001] This invention relates to the field of floor cleaning agent technology, specifically a highly efficient antibacterial cleaning liquid for intelligent floor scrubbers. Background Technology

[0002] With the advancement of technology, people's lives are constantly improving. The quality of life is increasing daily, and home cleaning is becoming increasingly intelligent. In particular, smart homes are now incorporating floor scrubbers, greatly simplifying daily cleaning.

[0003] The use of smart floor scrubbers has driven demand for chemical products, prompting research and development and quality improvement in chemical cleaning agents. The cleaning agents used in home smart floor scrubbers are household cleaning agents, primarily used for cleaning floors; they are also known as floor cleaners.

[0004] Currently, most floor cleaners on the market suffer from excessive foaming, which hinders the cleaning of floors by smart floor scrubbers. Furthermore, most floor cleaners on the market are weakly alkaline or weakly acidic; weakly acidic cleaners are corrosive. Using weakly alkaline cleaners for smart home cleaning can still harm people's health and may even result in poor stain removal.

[0005] To address the current technical challenges, further research is needed on floor cleaning agents for intelligent floor scrubbers to develop new products that are low-foaming, neutral, highly effective at removing dirt, and possess cleaning and sterilization properties. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of existing floor cleaning agents, such as high foaming, poor cleaning power, acid and alkali corrosion, and poor antibacterial properties, and to provide an environmentally friendly and efficient technology for cleaning home floors with a floor scrubber.

Next, add the organic solvent, defoamer, pH adjuster, and cashew phenol antibacterial agent containing triguanidine quaternary ammonium salt and stir for 5-10 minutes. Finally, add the fragrance and pigment to the mixing tank and stir for 10-20 minutes to obtain a highly effective antibacterial cleaning solution.

[0016] Preferably, the preparation method of the tribiguanyl quaternary ammonium salt cashew phenol antibacterial agent is as follows:

[0017] S1. Under nitrogen conditions, dicyandiamide is added to a 20-40% hydrochloric acid aqueous solution and stirred for 20-50 min. Then, tris(3-aminopropyl)amine is added, the temperature is raised to 60-80℃, and the reaction is carried out for 8-14 h. After the reaction is completed, the mixture is rotary evaporated, recrystallized, filtered, washed, and dried to obtain an intermediate containing tribisguanidine tertiary amine.

[0018] S2. Add cashew phenol and m-chloroperoxybenzoic acid to dichloromethane solvent, stir and disperse, heat to 30-40℃, react for 2-5 hours, after the reaction is completed, filter, wash, distill under reduced pressure and dry to obtain epoxidized cashew phenol;

[0023] Beneficial technical effects

[0024] This invention uses tris(3-aminopropyl)amine and dicyandiamide as raw materials, and obtains a tribisguanidine-containing tertiary amine intermediate through a nucleophilic addition reaction. Utilizing the alkenyl groups contained in cashew nut shell phenol, an epoxidation reaction occurs under the oxidation of m-chloroperoxybenzoic acid to obtain epoxidized cashew nut shell phenol. Then, the tertiary amine groups in the tribisguanidine-containing tertiary amine intermediate undergo a quaternization reaction with the epoxidized cashew nut shell phenol to obtain a tribisguanidine-containing quaternary ammonium salt cashew nut shell phenol antibacterial agent. Finally, surfactants, detergent builders, chelating agents, the tribisguanidine-containing quaternary ammonium salt cashew nut shell phenol antibacterial agent, fragrance, and pigments are added to deionized water and stirred to obtain a highly effective antibacterial cleaning solution.

[0025] The highly efficient antibacterial cleaning solution prepared by this invention contains a large number of quaternary ammonium salt groups and biguanide groups. The quaternary ammonium salt groups are positively charged and can be attracted and adsorbed onto the negatively charged bacterial cell surface via electrostatic attraction. They bind to the phospholipid bilayer and other negatively charged substances in the cell membrane, disrupting the cell membrane, causing the release of intracellular substances, and leading to bacterial death. The biguanide groups can coagulate bacterial proteins, teichoic acid, and lipopolysaccharides through flocculation, disrupting the osmotic barrier of the bacterial cell membrane, causing nutrient loss, and achieving an antibacterial effect. Furthermore, the highly efficient antibacterial cleaning solution prepared by this invention, after experimentation, exhibits better low-foaming, detergency, and neutral properties, solving problems related to high foaming, weak detergency, and weak acid / alkalinity.
