In the preparation process of dynamic covalent polymer expanded material, mainly using mechanical foaming method, physical blowing method, change Three kinds of methods of foaming are learned to foam to dynamic covalent polymer.
Wherein, the mechanical foaming method is by strong stirring in the preparation process of dynamic covalent polymer big Amount air or other gases are introduced into lotion, suspension or the solution of polymer and make uniform foams, then pass through Physically or chemically variation is allowed to be gelled, cures and become foamed material.To shorten, molding cycle can be passed through air and addition emulsifies Agent or surfactant.
Wherein, the physical blowing method is using physical principle in the preparation process of dynamic covalent polymer come real The foaming of existing polymer, generally comprises following four method:(1) inert gas blown method, i.e., inertia under pressurized condition Gas is pressed into molten polymer or pasty material, and then decompression heating, makes the gas expansion of dissolving and foam;(2) using low Boiling-point liquids evaporation gasification foaming, i.e., be pressed into low-boiling point liquid in polymer or under certain pressure, temperature regime, make liquid Body dissolves in polymer beads, then heats and softens polymer, and liquid also gasifies therewith evaporation and foamed;(3) leaching, i.e., It is immersed in polymer with liquid medium and dissolves the solid matter added in advance, make to occur a large amount of holes in polymer and be in hair Blister, such as by solable matter salt, starch elder generation and mixed with polymers, water is placed on after being shaped to product, then by product In handle repeatedly, solable matter is dissolved out to get to open-celled foam product;(4) hollow microsphere method is added in the plastic Become obturator-type foamed plastics through solidification after hollow microsphere;Wherein, preferably by dissolving in inert gas and low in the polymer The method of boiling-point liquids foams.Using physical blowing method, have operation Poisoning smaller, foaming raw material cost is relatively low, hair The advantages that infusion noresidue body.Further, it is also possible to be prepared using freeze-drying.
Wherein, the chemical blowing process is generated along with chemical reaction in dynamic covalent polymer foaming process Gas and the method to foam, generally comprise following two methods:(1) thermal decomposable foaming agent foaming utilizes chemistry hair The gas decomposed to give off after infusion heating foams.(2) it interacts between polymers compositions and generates the foaming of gas, i.e., it is sharp With the chemical reaction occurred between two or more components in foaming system, inert gas (such as carbon dioxide or nitrogen) is generated Polymer is caused to expand and foam.Polymerisation and foamable reaction balance carry out in order to control in foaming process, to ensure that product has A small amount of catalyst and foam stabiliser (or surfactant) is generally added in preferable quality.Wherein, preferably by polymer The method of middle addition chemical foaming agent foams.
