As can be seen from the data of examples 1 to 6 in Table 1, the propellant compositions of the present invention, in the case of propane-butane, are flammable or non-flammable in the class of flammability, when the mass fraction of propane-butane in the propellant composition is from 85 to 90%, the mass fraction of HFO-1234ze is from 9 to 13% and the mass fraction of inert gas is from 1 to 2%, have a burning distance of < 60cm, the burning distance is significantly shorter, and when the mass fraction of propane-butane in the propellant composition is 88%, the mass fraction of HFO-1234ze is 10.5% and the mass fraction of nitrogen is 1.5%, have a burning distance of < 15cm, the class of flammability changes from flammable to non-flammable.
As can be seen from the data of examples 7 to 12 in Table 1, the propellant compositions of the present invention, in the presence of dimethyl ether, are flammable or non-flammable in the class of flammability, with a mass fraction of dimethyl ether in the propellant composition of 87 to 91%, a mass fraction of HFO-1234ze of 7 to 12% and a mass fraction of nitrogen of 1 to 2%, having an ignition distance of < 60cm and a significantly shorter ignition distance, and with a mass fraction of dimethyl ether in the propellant composition of 89%, a mass fraction of HFO-1234ze of 9.5% and a mass fraction of nitrogen of 1.5%, having an ignition distance of < 15cm, having a flammability rating of from flammable to non-flammable.
Further, as can be seen from comparative example 3 and comparative example 1, in the propellant composition containing propane and butane, when the propane and butane content is unchanged but HFO-1234ze is absent, the ignition distance of the propellant composition becomes significantly longer and its flammability rating changes from non-flammable to extremely flammable, as can be seen from comparative example 3 and comparative example 2, when the propane and butane content is unchanged in the propellant composition, when the HFO-1234ze content is less than 4.5%, the ignition distance of the propellant composition becomes significantly longer and its flammability rating changes from non-flammable to extremely flammable, as can be seen from comparative example 3 and comparative example 4, when the HFO-1234ze content in the propellant composition is more than 18%, the ignition distance of the propellant composition becomes significantly longer and its flammability rating changes from non-flammable to extremely flammable, as can be seen from propane and butane containing propellant compositions, when the HFO-1234ze content is lower (less than 4.5%), HFO-1234ze does not inhibit combustion, and when the content of HFO-1234ze is in a certain range (4.5-18%), HFO-1234ze inhibits combustion, but when the content of HFO-1234ze exceeds 18%, its ability to inhibit combustion disappears, becoming combustion-promoting.
Further, it can be seen from comparative example 9 and comparative example 5 that in the propellant composition containing dimethyl ether, when the dimethyl ether content is unchanged but HFO-1234ze is absent, the ignition distance of the propellant composition becomes significantly long and its flammability class changes from non-combustible to extremely combustible, from comparative example 9 and comparative example 6 that when the dimethyl ether content is unchanged in the propellant composition, when the HFO-1234ze content is less than 3.5%, the ignition distance of the propellant composition becomes significantly long and its flammability class changes from non-combustible to extremely combustible, from comparative example 9 to comparative example 7 and comparative example 8 that when the HFO-1234ze content in the propellant composition is more than 13%, the ignition distance of the propellant composition becomes significantly long and its flammability class changes from non-combustible to extremely combustible, as illustrated in the propellant composition containing dimethyl ether, when the HFO-1234ze content is low (less than 3.5%, the ignition distance of the propellant composition is significantly long and its flammability class changes from non-combustible to extremely combustible, as illustrated in the propellant composition containing dimethyl ether, HFO-1234ze does not inhibit combustion, and when the content of HFO-1234ze is in a certain range (3.5-13%), HFO-1234ze inhibits combustion, but when the content of HFO-1234ze exceeds 13%, its ability to inhibit combustion disappears, becoming combustion-promoting.
The propellant composition disclosed by the invention has the advantages that the flammability grade of the final aerosol is reduced to be flammable or non-flammable by using the specific components and the component contents, the extremely flammable condition is avoided, and the safety of the aerosol product in production, storage, transportation and use is enhanced.
