Problems solved by technology

In order to change this state, people have developed small-environment cooling agents, such as U.S. Patent US4813238 and U.S. Patent US498314, which provide two cooling formulas for automobile cabs. The main components of the formula are methanol, ethanol and water, and added Sodium benzoate, so there are big problems: ①The alcohol smell of methanol and ethanol is too strong, harmful to human body, and flammable
② Sodium benzoate is not easy to volatilize, so it drips on the glass, leather, instrument and other objects in the cab, leaving a lot of white stains after drying, making the interior of the car dirty
③There is morpholine in the formula, which makes the solution smell bad and affects people's mental state
④ There is essence in the formula, which makes the solution volume emulsion, which is not conducive to the vaporization of the solution; and the oil-water phase of the essence is easy to occur, which directly affects the vaporization and causes waste. In addition, the cost is increased due to the large amount of essence used

Embodiment 1

[0013] The refrigerant is composed of 75% (v / v) water, 25% (v / v) ethanol, 0.01 (v / v) mint essence, and 0.02% (wt) sodium lauryl sulfate. Put this refrigerant into a common propellant type air tank, propellant:refrigerant=1:4(v / v). It is used for rapid cooling of car cabs and small restaurants, and can cool down by 13°C within 10 seconds.

Embodiment 2

[0015] By 84% (v / v) water, 15% (v / v) ethanol, 0.2 (v / v) jasmine essence, 0.8% (wt) polyoxyethylene sorbitan monolaurate composition refrigerant, its The refrigerant is put into the commonly used mechanical pump pressure aerosol tank, and sprayed and atomized by manual pump pressure. It is used for rapid cooling in darkrooms, entertainment rooms, etc. It can reduce the room temperature from 40°C to 31°C within 10 seconds.

Embodiment 3

[0017] By 90% (v / v) water, 10% (v / v) ethanol, 0.01% (v / v) white orchid oil, 0.001% (wt) octadecyltrimethylammonium aluminium, 0.0001% (wt ) lauryl dimethylaminoacetic acid trimethylamine betaine to form refrigerant, this refrigerant is packed in the commonly used propellant type aerosol can, propellant: refrigerant=1: 4 (v / v), add in propellant 2% dimethyl ether. The refrigerant is used for rapid cooling of family living rooms, and can reduce 38°C to 30°C within 10 seconds.

Abstract

The invention provides a small-environment quick refrigerant and a preparation method thereof. The refrigerant consists of 9 to 25 percent (volume / volume) of ethanol, 75 to 91 percent (volume / volume) of water and 0.0001 to 1 weight percent of surfactant. The preparation method comprises the following steps of: adding the ethanol into spice, stirring the mixture uniformly, adding the mixed solution into the water, stirring the solution uniformly and standing the solution. When a propellant is used, the propellant is added into the solution. The refrigerant has good refrigeration effect and high cooling speed, reduces the temperature by 2 to 15 DEG C in 10 seconds, and is economic, safe, sanitary, sterilized and suitable for quick refrigeration of various small environments.

Description

Technical field: [0001] The invention relates to a novel refrigerant, which belongs to the category of small environment refrigeration. Background technique: [0002] In summer, in some small environments, such as restaurants, entertainment rooms, family living rooms, car cabs, etc., due to poor ventilation and continuous heating, the temperature in small environments is often above 30°C, or even higher, which is unbearable. , even if the air conditioner is installed, it will take more than ten minutes to make people feel comfortable after turning on the machine. In order to change this state, people have developed small-environment cooling agents, such as U.S. Patent US4813238 and U.S. Patent US498314, which provide two cooling formulas for automobile cabs. The main components of the formula are methanol, ethanol and water, and added Sodium benzoate, so there are big problems: ①The alcohol smell of methanol and ethanol is too strong, harmful to human body, and flammable. ...
