Abstract
The temp-reducing agent consists of alcohol 9-25 vol% and water 75-91 vol%. It has fast temp-reducing effect, i.e., reducing the temp by 2-15 deg.C in 10 seconds, and is economic, safe and sanitary. It is suitable for reducing temp in small environment.
Description
The present invention relates to the subenvironment cooling agent.
In summer, in some subenvironments, as between automobile cab, microcomputer room, family life, between darkroom, dining room, playroom, device control etc., because the difference and continue to be heated of ventilating, the subenvironment temperature is usually up to 35-60 ℃, even higher, makes the people be difficult to stand.Even load onto air-conditioning, electric fan, also need open about back ten minutes and just can reach the temperature that makes the people comfortable.In order to change this situation, people have developed fast small-environment temp-reducing agent.As U.S. Pat 4813238, provide a kind of ejection vaporization heat absorption that utilizes ethanol-aqueous solution to make the method for automobile cab cooling.The major defect of this patent is: ethanol content height in the prescription, is the 20-50%Wt (25%-63%V/V) of gross weight, thereby makes the product cost height, and the ethanol flavor is too big, and pungency, inflammable is arranged.U.S. Pat 4983314 provides a kind of prescription that makes the automobile cab cooling fast.The main component of this prescription is a methanol-water solution, also is to utilize solution ejection vaporization heat absorption to lower the temperature.The major defect of this patent is: 1. used the methyl alcohol of 5-15% (V/V) in the prescription, because a large amount of evaporations of methyl alcohol are big to the harm of human body; 2. contain the Sodium Benzoate of 0.5% (W/W) in the prescription, because the non-volatility of this material,, stay a large amount of white stains after doing, make in the car dirty so droplet is fallen on the objects such as the glass, leather, instrument of wheel house; 3. the morpholine of 0.2% (V/V) makes solution smell variation in the prescription.It is the automobile cab cooling agent of major ingredient that Chinese patent application CN1069047 has proposed by ethanol-water.The defective of this patent is: 1. because ethanol consumption too little (75% ethanol 5-12% (V/V)) makes the solution vaporization effect not good, cooling-down effect is poor.2. use food flavour (5-12% (V/V)) in a large number, make solution easily be emulsion, be unfavorable for the solution vaporization, and the profit phase-splitting of essence takes place easily, in addition because a large amount of food flavour that uses improves product cost.
The object of the present invention is to provide the fast small-environment temp-reducing agent of a kind of economy, safety, good cooling effect.
The present invention proposes according to the throttling of solution vaporization decalescence principle.
The present invention is made up of the second alcohol and water.Wherein, ethanol content is 9-25% (V/V), and the content of water is 75-91% (V/V).Water of the present invention is as main vaporization decalescence material, and ethanol is as auxiliary vaporization decalescence material.Because the ethanol consumption is suitable, thereby makes solution spray instant vaporization in throttling; Simultaneously, the vaporization degree of second alcohol and water has difference, and the droplet of feasible ejection improves atomizing effect at the droplet of further quick-fried pure Cheng Gengxiao of moment.Ethanol in the present invention's prescription can partly substitute with other low-carbon alcohol.
In order further to improve cooling-down effect, can add tensio-active agent 0.0001-1% (W/t) in the present invention.Utilize tensio-active agent itself, and act synergistically, can greatly reduce the surface tension of solution, make the easier quick-fried essence of solution and be dispersed into aerosol particles with alcoholic acid.Simultaneously, also can improve the solvability of oil phases such as spices.The selectivity of odor type is enlarged.The used tensio-active agent of the present invention can be anionic, cationic, amphoteric, non-ionic type, fluorine-containing type, polymer, biotype and other special surface promoting agent, and the mixing of these type list surface-active agents be used.Allocating into of tensio-active agent, except that reducing solution surface tension and solubilising oil phase, the sterilization that himself had, character such as antistatic, anticorrosion also become characteristics of the present invention.
The present invention and throttling atomisation unit are used.The throttling atomisation unit can be the throttling atomisation unit of the aerosol jar that propelling agent is housed, mechanical pump pressure type throttling aerosol jar or other form used always.The aerosol jar of propelling agent is housed when use, can in propelling agent, add an amount of dme and (or) carbonic acid gas, propane, butane, hydrocarbons such as Trimethylmethane utilize the throttling atomizing phase-splitting of these materials, make quick-fried broken, the disturbance of droplet, further improve the atomization and vaporization effect.Propelling agent type and consumption require according to the product design pressure criteria and decide.
Can add different spices as required in the present invention.
Preparation of the present invention is in proper order: earlier spices is added ethanol, then ethanol is added tensio-active agent, the mixed solution with spices, ethanol, tensio-active agent adds in the entry again.When relating to propelling agent, in above-mentioned solution, add propelling agent again.
Advantage of the present invention is: good cooling effect, ethanol consumption suitably and the adding of tensio-active agent have reached best atomizing effect; Cooling rate is fast, and cooling is 2-15 ℃ in 10 seconds; Economy, safety, health.And can sterilize, antistatic, protection against corrosion.Be applicable to various fast small-environment temp-reducings.
