Self-cleaning plastic rain shoe with super-amphiphobic coating layer

Abstract

The invention discloses a self-cleaning plastic rain shoe with a super-amphiphobic coating layer, the surface of the plastic rain shoe is sprayed with the super-amphiphobic coating layer, and a preparation method of the self-cleaning plastic rain shoe comprises the following steps: S1, preparing a rain shoe blank from PVC resin, carbon black, diethylene glycol, a plasticizer, a flexibilizer and an anti-aging agent; S2, preparing a hydrophobic waterborne polyurethane emulsion and modified titanium dioxide nanoparticles, and then mixing the hydrophobic waterborne polyurethane emulsion, the modified titanium dioxide nanoparticles and auxiliary materials to prepare a super-hydrophobic spray paint, and S3, uniformly spraying the super-hydrophobic spray paint prepared in the step S2 on the surface of the plastic rain shoe blank, and curing to obtain the plastic rain shoe. The super-amphiphobic coating layer is sprayed on the surface of the plastic rain shoe, the super-amphiphobic coating layer is prepared by taking the hydrophobic waterborne polyurethane emulsion and the modified titanium dioxide nanoparticles as main raw materials, the coating layer shows super-hydrophobicity and oleophobicity, and the plastic rain shoe adopting the super-amphiphobic coating layer has a self-cleaning function.

Description

technical field [0001] The invention relates to the field of rain boot production, in particular to a self-cleaning plastic rain boot with a superamphiphobic coating. Background technique [0002] Rain boots are water-proof shoes worn in rainy days. The style of rain boots is not uniform. The appearance of short rain boots is similar to sneakers; the height of medium rain boots is about 10 cm above the ankle; Ordinary people often wear medium and low rain boots, and some professionals in special types of work need high rain boots as labor protection supplies for rain-proof or water-logged operations. Rain boots are divided by material: rubber rain boots, PVC rain boots, EVA rain boots, etc. [0003] During daily use, rain boots will be oxidized, and the sun and high temperature can accelerate the aging speed, making them hard and soft. At the same time, rain boots are often used in water-logged environments or workshop environments, and are easily contaminated by the exter...
