Abstract
The aerosol propellant consists of dimethyl ether in 60-70 weight portions, common propellant in 1-12 weight portions, water in 22-33 weight portions and antioxidant in 0-0.005 weight portions. It has low toxicity, incombustibility, no explosion and no need of shaking, and may be used pesticidal aerosol, medical aerosol, etc.
Description
Invention field
The present invention relates to a kind of not quick-fried environment-friendly type aerosol propellant that need not shake that efficiently do not fire.
Background technology
Along with eliminating of CFC material, aerosol propellant substitutes with hydrocarbon (as propane, butane etc.) at present, but their greatest problem is inflammable, explosive, exists potential safety hazard.Hydrocarbon exists VOCS (organic compound excessive vaporization) and GWP (greenhouse effect) problem simultaneously.Also have these oily matters to be difficult for and other materials, particularly water-soluble substances mixes.Therefore, the aerosol effect is undesirable, need shake emulsification and could release, and continues layering then.
China's aerosol year consumption per capita is listed as the 4th reciprocal of the world less than 0.4 jar, and year every raising of consumption figure is 0.1 jar per capita, just means that annual production will improve 1.2 hundred million jars.More wide in other range of application, the desinsection harmful aerosol that goes out for example, air freshener, hair spray, the mousse cosmetics, traffic and peculiar to vessel, medicinal aerosol etc. potential great market.
Summary of the invention
The present invention is primary raw material with the dimethyl ether, and that science makes is nontoxic, do not fire, not quick-fried, environmental protection, aerosol propellant efficiently.
The purpose of this invention is to provide a kind of aerosol propellant, comprise following component:
The dimethyl ether of 60-70 weight portion,
The propellant commonly used of 1-12 weight portion,
The solvent of 22-40 weight portion and
0-0.005 part antioxidant of weight.
Aerosol propellant of the present invention preferably includes:
The dimethyl ether of 64-66 weight portion,
The propellant commonly used of 1-10 weight portion,
The solvent of 25-30 weight portion and
0-0.003 the antioxidant of weight portion.
Propellant wherein commonly used can be any propellant, for example comprises iso-butane, propane, butane etc.Iso-butane is preferred the use.Propellant commonly used can also comprise carbon fluorohydrocarbon class, but this is not preferred.
Wherein solvent can be selected from any solvent that this area is usually used in aerosol, water for example, ethanol, ethanol water, propyl alcohol, isopropyl alcohol etc.Water wherein, ethanol, ethanol water are preferred.
Antioxidant uses under the situation of using canister, in case chamber wall gets rusty.They can be any antioxidant of this area, for example phenols and amine antioxidants.
Another object of the present invention provides medicinal aerosol, comprises the active constituents of medicine of above-mentioned aerosol propellant and effective dose.
Another purpose of the present invention provides insect aerosol, comprises the insecticide of above-mentioned aerosol propellant and effective dose.
Aerosol propellant of the present invention can also be used for hair spray, mousse cosmetics, go out fly or mosquito aerosol, or other any aerosol or spray.
Above-mentioned aerosol or spray preparing process are known in those skilled in the art, can carry out according to common aerosol or spray preparing process, and can find in existing document or patent disclosure specification.
The advantage of aerosol propellant of the present invention comprises:
1, mixes with water-soluble or oil-dissolving solvent, need not shake, can all release, do not stay residual thing.
2, also can dissolve each other with general organic matter (as hydrocarbon, alcohols, ester class, ethers, acetone, amide-type, aldehydes, paint, resin etc.).
3, do not destroy other component in the solution.
4, toxicity is very low, and is almost non-toxic.
5, pure environment-friendly type, the ODP value is 0, GWP is also very little.
6, do not burn (as aerosol, its flammability is better than international standard).
7, alternative freon, propellants such as propane, performance is better than like product.
8, be about 70% of traditional handicraft cost.
