Aerosol propellant compositions
摘要：
The present invention concerns new propellant compositions for aerosols. More particularly, the present invention relates to propellant compositions for aerosols, characterized in that said compositions consist of a mixture of a chlorofluorocarbon or fluorocarbon (A) containing hydrogen and selected from the group consisting of CHClF.sub.2, CH.sub.2 F.sub.2 and CF.sub.3 --CH.sub.3, with a chlorofluorocarbon or fluorocarbon (B) containing hydrogen and selected from the group consisting of: CH.sub.2 ClF, CClF.sub.2 --CHClF, CF.sub.3 --CHClF, CHF.sub.2 --CClF.sub.2, CHClF--CHF.sub.2, CF.sub.3 --CH.sub.2 --Cl, CHF.sub.2 --CHF.sub.2, CF.sub.3 --CH.sub.2 F, CClF.sub.2 --CH.sub.3 and CHF.sub.2 --CH.sub.3. In addition to propellant A and propellant B, there may be included a hydrocarbon propellant so that a ternary propellant composition is provided.
摘要（中）：

本发明涉及用于气溶胶的新的推进剂组合物。 更具体地说，本发明涉及用于气溶胶的推进剂组合物，其特征在于，所述组合物由含氟氢氟烃（A）和含有氢的选自CHClF 2，CH 2 F 2和CF 3 -CH 3的混合物与氯氟烃 或碳氢化合物（B），并且选自：CH 2 ClF，CClF 2 -CHClF，CF 3 -CHClF，CHF 2 -CClF 2，CHClF-CHF 2，CF 3 -CH 2 -C 1，CHF 2 -CHF 2，CF 3 -CH 2 F，CClF 2 -CH 3 和CHF 2 -CH 3。 除了推进剂A和推进剂B之外，还可以包括烃推进剂，从而提供三元推进剂组合物。
