Abstract

The invention discloses an organic silicon oxygen-enriched membrane and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing 107 glue, methyl methacrylate and gutta-percha, heating to 55-65 DEG C, dropwise adding a benzoyl peroxide solution, maintaining the temperature of a reaction system at 80-90 DEG C, reacting for 2-3 hours, then intermittently vacuumizing until a reactant is semitransparent, and cooling to obtain a base material; and uniformly stirring the base material, organic tin and methyltris (methylethylketoximino) silane, exhausting steam in vacuum, and molding to obtain the organic silicon oxygen-enriched membrane. The oxygen-enriched membrane can effectively solve the problem of poor mechanical property of the existing organic silicon oxygen-enriched membrane.

Description

technical field [0001] The present invention relates to Background technique [0002] Silicone copolymers have many excellent properties, such as high and low temperature resistance, physiological inertness, gas permeability, etc., but they have solvent resistance, poor mechanical properties, and high cost. In order to develop its wide range of uses, the use of silicone polymers and Copolymerization of other organic polymers can make up for the shortage of silicone polymers. [0003] Modification by graft copolymer is the main method of modification developed in the 1970s. It is easy to operate and environmentally friendly. It has been widely used in the synthesis of new materials in recent years. [0004] The principle of the method is to use the unsaturated bond on the main chain of silicone and the olefin bond to graft onto the main chain of silicone under the action of a catalyst, so as to form the common properties of two different molecular polymers and achieve the pu...
