Abstract

The non-inflammable aerosol composition consists of dimethyl ether, ethanol and fire retardant. The fire retardant is fluorohydrocarbon, fluorochlorohydrocarbon, ketone fluoride or their mixture. The aerosol composition has high solubility, non-inflammability, low toxicity, adjustable pressure and ODP value of 0-0.1.

Description

technical field [0001] The invention relates to the field of organic chemical industry, in particular to a non-combustible aerosol composition. technical background [0002] In the prior art, an aerosol composition is a dimethyl ether and ethanol composition. This aerosol composition has good solubility, good atomization effect, does not destroy the atmospheric ozone layer, and has an ODP value of 0, but is easily Combustible, easy to cause explosion and fire during use. [0003] The improvement of this aerosol is to add an appropriate amount of R12 and R11, which eliminates the danger of inflammability and explosion. R12 or a mixture of R12 and R11 is itself an aerosol. However, R12 and R11 will destroy the ozone layer of the atmosphere, and the ODP value is 1, which is prohibited by some international conventions. Contents of the invention [0004] The first object of the present invention is to provide an aerosol composition which has good dissolving power, is non-fl...
