Abstract

The invention provides a flexible material with a self-cleaning function and a preparation method and application thereof.The flexible material comprises a base layer and a self-cleaning coating layer, the self-cleaning coating layer is arranged on the surface and / or inside the base layer, and the self-cleaning coating layer is made of fluorine-containing hydrophobic and oleophobic coating and an antistatic agent. The flexible material is good in waterproof performance, high in oil stain resistance and capable of self-cleaning accumulated dust, the oil repellent grade is 3-8, meanwhile, the flexible material has stable sound transmission and air permeability, and has stable frequency response within the range of 100-10 KHz, and fluoride and an antistatic agent which are excellent in performance are adopted in the preparation method of the flexible material; the material with better hydrophobic, oleophobic and self-cleaning properties is obtained by controlling a plurality of process parameters such as the solid content of the fluorine-containing hydrophobic and oleophobic coating in the self-cleaning solution in the dip-coating process of the base layer material, the solid content of the antistatic agent, the liquid outlet angle of the base layer, the feeding speed, the drying temperature and the like.

Description

technical field

[0001] The invention belongs to the field of flexible materials, and in particular relates to a flexible material with self-cleaning function and its preparation method and application. Background technique

[0002] At present, smart devices have become an indispensable tool in life, such as mobile smart hardware such as mobile phones, watches, earphones, smart speakers, and smart glasses, as well as smart home appliances such as smart toothbrushes, smart range hoods, smart rice cookers, and smart refrigerators. There must be a through hole on each device, one is the function of transmitting sound, such as receivers, microphones, speakers, etc., the main purpose is to ensure the smooth progress of audio information collection and transmission. Another function is to transmit air, such as ventilation holes and audio adjustment holes. The main purpose is to balance the air pressure difference and sound pressure difference inside and outside the equipment. [0...
