Abstract

The invention relates to a method for preparing a self-cleaning anti-icing rubber surface by use of a waste silicone rubber product and belongs to the technical field of surface chemistry. The method comprises the following steps: fully combusting a waste silicone rubber product; grinding obtained combustion products into powder; spreading the powder on a well-shaped mixing rubber surface; placing rubber on which the powder is spread into a die, and performing high-temperature vulcanization shaping in a press vulcanizer; after demoulding, cleaning to obtain a super-hydrophobic rubber surface. The method is simple and convenient, realizes waste utilization, is environment-friendly, dispenses with a special processing instrument and therefore is low in cost. The manufactured super-hydrophobic surface adopts a micro/nano dual structure, and a micro bulge structure has high super-hydrophobicity, self-cleaning capability and favorable mechanical stability, has a favorable application prospect and is expected to realize industrial production.

Description

technical field [0001] The invention relates to a method for preparing a self-cleaning anti-icing rubber surface by using waste silicon rubber products, and belongs to the technical field of surface chemistry. Background technique [0002] Researchers are inspired by the creatures in nature, such as the surface of lotus leaves, rice leaves, water strider feet, etc., to study superhydrophobic surfaces, and call the surface wetting phenomenon with a water contact angle of more than 150° and a rolling angle of less than 10° as superhydrophobic surface. Lotus effect (lotus effect). Studies have shown that there are two factors affecting surface wetting properties, surface chemical composition and special microscopic geometry. After decades of research, researchers have proposed different theoretical models to explain the influence of surface structure on the surface wetting properties of materials, the most typical and famous of which are the Wenzel complete wetting model and t...
