Abstract

The invention discloses a method of preparing an isotropic super-hydrophobic and superoleophobic regular porous silicone rubber with an anisotropic structure. The method comprises the following stepsof (1) uniformly mixing silicone oil containing C=C double bond, inorganic nanometer filler, a catalyst and an inhibitor to obtain a first mixture; (2) adding hydrogen-containing silicone oil and a silicone rubber additive in the first mixture prepared in the step 1, performing uniform mixing to obtain a second mixture, and performing defoaming to obtain ink for printing; (3) charging the ink in a3D printer, and performing printing according to the anisotropic porous structural characteristics to prepare silicone rubber with a porous structure; and (4) performing pre-solidification treatment,then performing dip coating and drying on the treated silicone rubber in a treating agent solution, performing superthermal hydrogen treatment, taking out the treated silicone rubber for cleaning, and then performing drying again to obtain the isotropic super-hydrophobic and superoleophobic silicone rubber material. According to the method provided by the invention, by combining the silicone rubber with the inorganic nanometer filler, organic combination of a physical structure and the material characteristics is realized by utilizing 3D printing, and the isotropic super-hydrophobic and superoleophobic silicone rubber is prepared.

Description

technical field

[0001] The invention belongs to the field of superhydrophobic and superoleophobic porous silicone rubber, and in particular relates to an isotropic superhydrophobic and superoleophobic silicone rubber material directly prepared by 3D printing anisotropic structures. At the same time, the above-mentioned silicone rubber material has excellent mechanical stability, porous super-hydrophobic and super-oleophobic properties, and a preparation method of the silicone rubber is provided. Background technique

[0002] The wettability of the material surface is usually determined by the physical structure and chemical composition of the material surface. According to whether the physical structure and / or chemical composition are consistent in different directions, the wettability of the material surface can be divided into isotropic wettability and wettability. Anisotropic wettability. Among them, isotropic wettability means that the wettability of the material surfac...
