Problems solved by technology

The super-water performance of the surface is controlled by both the surface chemical properties and the surface morphology. At present, methods such as doping, etching, spraying, phase separation, and templates are commonly used to control the surface morphology. Due to the constraints of processing conditions, these methods are difficult to expand their applications. , although there have been more and more literature reports on the research on superhydrophobic surfaces, there are still many problems in its practical application, which need further research to solve

Abstract

The invention provides an acrylonitrile-butadiene-styrene (ABS) resin material with a self-cleaned surface and a preparation method thereof. The ABS resin material consists of the following raw materials in percentage by mass: 0.1 to 5 percent of micron and nanometer aluminum powder, and 95 to 99.9 percent of ABS particles. Pits with micron and nanometer structures can be formed on the surface ofan ABS sheet, and partial air is left in the pits to ensure that liquid drops fail to completely fill into the pits because sizes of the pits are smaller than those of the liquid drops, so that the ABS resin material has hydrophobic property; moreover, the micron and nanometer aluminum powder is used as a template, diluted hydrochloric acid is used as a dissolving agent, and raw materials are readily available; and a manufacturing process is simple, the operation is simple and convenient, the investment is low, and the operation cost is low.

Description

technical field [0001] The invention relates to an ABS resin material, in particular to a surface self-cleaning ABS resin material and a preparation method thereof, belonging to the technical field of functional materials. Background technique [0002] Health, energy saving and environmental protection have become the main trends in the future development of household appliances. ABS resin has been widely used in home appliances due to its superior mechanical and chemical properties. Amphiphobic technology and nanotechnology also have good application prospects for the self-cleaning of the surface of home appliances and refrigeration systems. By studying the microstructure of superhydrophobic lotus leaves, people know that the wettability of solid surfaces is mainly determined by the chemical composition and three-dimensional microstructure of the surface, which provides new ideas and methods for preparing biomimetic superhydrophobic surfaces. The super-water performance of...
