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 ABS hydrophobic and oleophobic material with surface loaded by TiO2 / diatomite, and a preparation method thereof. The ABS hydrophobic and oleophobic material is composed by the following raw materials by mass: 98-99.9% of an ABS resin and 0.1-2% of a TiO2 / diatomite composite photocatalytic material. The ABS hydrophobic and oleophobic material with the surface loaded by TiO2 / diatomite is obtained by the steps of A. firstly preparing the TiO2 / diatomite composite photocatalytic material, B. dispersing the TiO2 / diatomite composite photocatalytic material in ethanol to form a suspension liquid, and C. coating the suspension liquid on the surface of a mold, then keeping ABS resin particles at the temperature of 100-140 DEG C for 10-30 min, and compression molding at the temperature of 150-180 DEG C; or keeping the ABS resin particles at the temperature of 100-140 DEG C for 10-30 min, compression molding at the temperature of 150-180 DEG C, then coating the suspension liquid obtained by the step B on the surface of the compression molded ABS resin material, and then compression molding at the temperature of 150-180 DEG C. The ABS hydrophobic and oleophobic material has the characteristics of super-hydrophobic surface self-cleaning effect and self-cleaning capacity. The preparation method is simple in process, simple in operations, small in investment, low in operation cost and no pollution to environment.

Description

technical field [0001] The invention relates to an ABS resin material, in particular to an amphoteric, deodorizing, mildew-removing and antibacterial ABS resin material with surface self-cleaning effects 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 prepar...
