Description
(1) technical field
The present invention relates to the synthesis of a kind of hexahedron silsesquioxane-based dissaving polymer and at supercritical CO2Application in foaming.
(2) background technology
Polymer micro expanded material refers to have the diameter abscess less than 10um and cell density 109~1015Individual/cm3A kind of Novel foam material. Compare unfoamed polymeric material, microcellular foam material has light weight, with low cost, specific stiffness is high, impact strength is high, dielectric constant and the advantage such as heat conductivity is low, it is widely used in packaging, aircraft and auto parts and components, sports equipment, insulation insulant and bio-medical material etc., is a key areas of polymeric material application.
The method preparing polymer micro expanded material is a lot, but all follow a ultimate principle: make gas be dissolved in polymer first under an increased pressure and obtain homogeneous system, then pass through and be rapidly heated or the mode of blood pressure lowering makes gas reach hypersaturated state, at a suitable temperature, gas karyomorphism becomes and grows up, and finally sizing obtains microcellular foam material. In numerous foamed gas, supercritical CO2Having most application prospect, its critical temperature (Tc=31.1 DEG C) is relatively low, easily realizes operation near room temperature, and critical pressure is only 7.37Mpa, low for equipment requirements. Further, supercritical CO2Also have colourless, odorless, nontoxic, inexpensive, non-combustible, consume ozone latent energy value (ODP) and be zero, environmental friendliness, there is the advantages such as good chemical stability, it is expected to substitute the physical blowing agent of currently used more hydrochlorofluorocarsolvent (HCFCs) and poisonous CBA, is real " green foaming agent ".
Ionic liquid (IonicLiquid writes a Chinese character in simplified form IL) is the salt being in a liquid state under low temperature (< 100 DEG C), and it has good heat stability, major part ionic liquid can remain stable at 300~400 DEG C, and the close friend to environment, its application prospect is extensive, thus one of becomes the accumulation point of research in the present age.Substantial amounts of bibliographical information shows (first National Chemical engineering with biochemical industry nd Annual Meeting summary collection (on) .2004.11) (J.Phys.Chem.B, 2005,109:6366-6374) (J.Phys.Chem.B, 2002,106:7315-7320) (Chinese patent: CN200510073345.0,2005.12) CO2There is stronger interaction with partial ion liquid, it has significantly high dissolubility in ionic liquid. At present, ionic liquid CO absorption2And carry out polymer micro foaming research and be still in the experimentation stage, but it embodies excellent adsorptivity in foaming process and becomes nuclearity, and various novel ionic liquids are also constantly used for the research that polymer micro foams.
