Explanation of the invention (2) Formula (extraction) to achieve. The so-called extraction method is to combine two kinds of materials 'melt the mixture at a high temperature (about 160 ~ 180 ° C) by extrusion or injection', and then cool and shape it. Human solvents dissolve one of these substances, and the other undissolved substance handle: it will form a porous material. In this way, porous materials are prepared by extraction. During the dissolution process, there will often be solvent contamination. For materials with thicker thickness in double A, there will be longer extraction time, which will cause processing problems. Practical applications for preparing porous materials by extraction methods are, for example, mixing polyethylene (po 1 yet hy 1 e ne; PE) with common salt (NaC 1), extruding or ejecting, and then dissolving common salt with water or hot water. The main body of PE can form porous @ material; for another example, polypropylene (PP) and ethylene-propylene rubber (EPR) are mixed and processed, and then an appropriate solvent (such as heptane, heptane) dissolves the EPR to form a porous material mainly composed of PP. From the above two examples, the method of dissolving common salt in the manufacturing process is likely to cause the corrosion of the machine and the mold, which affects the service life of the machine; and the method of dissolving the EPR with the solvent will cause solvent pollution and Air pollution from the working environment on site. The shortcomings of the formulas and processes used to make porous materials are summarized as follows:

Time-consuming manufacturing process: In this procedure, it is a time-consuming step to dissolve the substance to be precipitated (such as table salt or EpR), and the thicker the product The longer it takes, 'the thicker the finished product is, because the solvent dissolves out the substance to be precipitated contained in the material body from the outside to the inside, the harder it is to dissolve the more substance inside. 3 · Energy Consumption: The salt used in the conventional technique is an incompressible and non-plasticizable substance with large particles (the finest salt that can be bought in China is 35 ° to π ° 'when used. The limit concentration to be added is also limited. In practice 011, the mixing ratio of the table and the plastic must be at least table salt: plastic = 3: j to form a material with water absorption effect, but such a high proportion of table salt filling, ') For extrusion or injection, it will cause a large torsional load and consume energy. 4 Environmental pollution and machine corrosion problems: In the production process, organic solvents are often used to analyze materials and systems. If the solvent is volatilized and affects the working environment, it will cause trouble during recovery; and = is a major injury, which will cause the high corrosion of the moisture and the operating life.
