Problems solved by technology

This will not only affect the refrigeration and heat dissipation of the air conditioner, but even endanger human health.
[0003] At present, air conditioner cleaners mainly include the following two types: (1) Completely chemically synthesized air conditioner cleaners. The ingredients of this type of cleaners are all chemically synthesized substances, which can be divided into acidic or alkaline cleaners, and their decontamination effect is fast. The antibacterial function is remarkable, and it is the mainstream of air conditioner cleaners in the current market, but its operation is complicated, and acidic or alkaline substances will cause strong corrosion to aluminum, copper and stainless steel and other air conditioner parts, which will increase the cost of use; although some cleaners will Adding a certain amount of corrosion inhibitors such as metal chelating agents or acid corrosion inhibitors can reduce the occurrence of corrosion, but chemically synthesized substances will produce strong pungent odors during use, pollute the environment, endanger human health, and are expensive; at the same time , fungal substances are easy to produce resistance, which brings difficulties to subsequent antibacterial cleaning; (2) Partially chemically synthesized air conditioner cleaning agents, which are mainly composed of natural plant extracts with bactericidal functions and some chemically synthesized substances. , Chinese invention patents CN201510874472.4 and CN201610805925.2 respectively disclose ethanol extracts of Budapest, aloe, benzoin and borneol, ethanol extracts of peppermint, forsythia, benzoin and borneol, etc., and chemically synthesized surfactants and other chemical The method for preparing automobile air conditioner cleaning agent by mixing substances, the obtained product has the advantages of not corroding cleaning objects, being volatile and not producing irritating odor, and having obvious antibacterial effect, etc.
However, natural active ingredients have defects such as being insoluble in water, highly volatile, unstable, and easy to degrade, which have high requirements for industrial production links, and the effect of the cleaning agent made from this is not long enough, and alcohol-soluble will irritate the respiratory tract sex and other shortcomings
At present, there is no report on the preparation of foam cleaning agent for automobile air-conditioning system by compounding Litsea Cubeba essential oil with residual oil mother liquor

preparation example Construction

[0046] The preparation process of the remaining oil mother liquor used in the examples is as follows: put the leaves of plum slices into an extraction tank for steam distillation to obtain crude oil; then slowly cool and crystallize the crude oil, centrifuge, and filter, and the obtained filtrate is the remaining oil. Mother liquor;

[0047] The preparation process of the amino-functionalized silica nanoparticles used in the examples is as follows: add 24ml of ammonia water to a round-bottomed flask (500ml) of 300ml of absolute ethanol, stir for 5min, add 12ml of ethyl orthosilicate, and stir at room temperature overnight; in order to functionalize the surface of nanoparticles, 1.22ml of aminopropyltriethoxysilane was added to the above system, and stirred at room temperature for 24h. The reaction solution was washed with water, centrifuged and washed with alcohol for several times, then freeze-dried and kept in powder state for future use.

Embodiment 1

[0050] (1) Preparation of foam cleaner: Measure 150mL litsea cubeba essential oil and dissolve it in 280mL remaining oil mother liquor, stir well, add 520mL deionized water suspension containing 20.8g amino-functionalized silica nanoparticles, Adjust the 1mol / L NaOH solution to pH = 10, emulsify and homogenize for 10 minutes at the speed of 24000r / min, add 50mL of silicone oil (Shanghai Moye Industrial Development Co., Ltd.), mix well, seal, and store at 25°C in the dark 80 days; Filtration, the filtrate is a foam cleaner with high-efficiency antibacterial function, packaged in a special atomized spray bottle, and stored in the dark at room temperature.

[0051] (2) Performance testing

[0052] 1) Sensory evaluation: randomly arrange 40 testers to evaluate the prepared foam cleaner according to smell, color, etc., and score the foam cleaner (20 points in total). The scoring criteria are shown in Table 1.

Abstract

The invention belongs to the field of daily-use chemical industry, and discloses an automotive air-conditioner foam cleaning agent with a bacteriostatic function, and a preparation method and an application method thereof. The foam cleaning agent comprises litsea cubeba essential oil, a leftover oil mother liquor, dimethicone oil, amino-functionalized silica nanoparticle carrier particles and deionized water. According to the invention, an amino group of hydrophilic amino-functionalized silica and a main oil-phase component namely citral are utilized to generate an in-situ reaction at an interface position of water and oil, so Schiff base is generated, and water solubility of the amino-functionalized silica is reduced; the Schiff base is migrated to an oil-phase system without change of the unique nanometer morphology of the Schiff base; meanwhile, through emulsification homogenization, a stable O / W Pickering emulsion multichannel delivery system is obtained. The system makes up the defects like water insolubility, strong volatility, unstability, easy degradation and strong flavor which limit extensive application of natural active ingredients, and has good bacteriostatic functionat the same time.

Background technique [0002] After the car air conditioner has been used for a period of time, 80% of the tiny dust and bacteria in the air will pass through the filter and enter the interior of the air conditioner, bond with the condensed water and block the evaporator. If these dust and stains are not treated in time, it will Various problems can arise. This will not only affect the refrigeration and heat dissipation of the air conditioner, but even endanger human health. [0003] At present, air conditioner cleaners mainly include the following two types: (1) Completely chemically synthesized air conditioner cleaners. The ingredients of this type of cleaners are all chemically synthesized substances, which can be divided into acidic or alkalin...
