Embodiment 1

[0034] The preparation method of the Gemini quaternary ammonium salt surfactant shown in the following formula, concrete steps are as follows:

[0035]

[0036] 1) Mix 0.1mol propionic acid and 0.12mol NC 2 h 5 (CH=CHOH) 2 After mixing evenly, put it into the reflux device, add 50mL cyclohexane, 0.1g p-toluenesulfonic acid, 0.3g zinc powder, and reflux reaction at 110°C for 4 hours. Dry over sodium sulfate, evaporate the solvent in a rotary evaporator to obtain a residue, and then purify by column chromatography to obtain propionic acid-N-ethyl divinyl alcoholamine monoester with a yield of 94%;

[0037] 2) Mix 0.05mol of propionic acid-N-ethyldivinolamine monoester with 50mL of chloroform, add 5mL of triethylamine, and cool, then dropwise add a mild solution of 0.025mol of terephthaloyl chloride and 30mL of chloroform, After about 2 hours of dropping, after the dropping, stir and react at room temperature for 20 hours. After the reaction, the reaction solution is washed...

Abstract

The invention discloses a splash-proof foam agent based on a Gemini quaternary ammonium salt surfactant and a preparation method for the same. The splash-proof foam agent includes a surfactant, a foam stabilizer, a thickener, an emulsifier, a pushing agent, a sterilization cleaning agent and deionized water. The invention also discloses preparation methods for the Gemini quaternary ammonium salt surfactant and the splash-proof foam agent. The Gemini quaternary ammonium salt surfactant can stabilize foams and maintain a proper surface tension and certain strength of the foams, and also reduces the use amount of the foaming agent in the splash-proof foam agent without reduction on generation quantity of the foams. The splash-proof foam agent based on the Gemini quaternary ammonium salt surfactant can completely prevent water splashing generated when sewage falls into a collection container, and also has the effects of deodorization and is anti-bacterial. The splash-proof foam agent is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a splash-proof foaming agent based on a Gemini quaternary ammonium salt surfactant and a preparation method thereof. Background technique [0002] The toilet is a kind of convenient facility that is common in our country's family and hotel now, but there is no technology that can solve the technology of not splashing water and deodorizing when people are convenient, especially when defecating, the water of the toilet often splashes on the people's buttocks or On the clothes, it is very unhygienic and brings great inconvenience to the user. Most of the existing toilet cleaning and sterilization products are liquids, which are usually directly or indirectly added to the water tank, and enter the toilet when the water tank is flushed, so as to achieve the cleaning effect, but it cannot solve the above-mentioned problem of preventing toilet splashing. The problem. [0003] The inve...
