Abstract

The invention discloses a lubricant film material, a raw material composition, a preparation method and applications. The preparation method comprises following steps: electrostatic spinning films are prepared from spinning liquid A and spinning liquid B through electrostatic spinning; lubrication is performed on the electrostatic spinning films with lubricant; the spinning liquid A is obtained by solving hot melt adhesive in an organic solvent; the spinning liquid B is obtained by solving a hydrophobic polymer in an organic solvent; the melting point of the hot melt adhesive is lower than that of the hydrophobic polymer; the concentration of the hot melt adhesive in the spinning liquid A is 5 wt% to 30 wt%; the concentration of the hydrophobic polymer in the spinning liquid B is 5 wt% to 30 wt% The preparation method has simple process, mild preparation condition, low cost and high production efficiency and is suitable for industrial production; the produced lubricant film material is transparent, has excellent waterproof and oil-proof performance, high mechanical strength and can be used repeatedly, and is especially suitable for water resistance, fog resistance, freezing resistance and oil resistance of glass surface.

Description

technical field [0001] The invention relates to a lubricating film material, raw material composition, preparation method and application. Background technique [0002] Solid surfaces with self-cleaning and antifouling properties hold great promise in industry and daily life. However, most of the current self-cleaning surface preparation methods have problems such as low efficiency, complicated process, expensive equipment, high operating technology requirements, and harsh reaction conditions. They are limited to laboratory research and are difficult to promote and apply in industry. [0003] Electrospinning is a technique for preparing fiber membrane materials by applying a high-voltage electric field to a polymer solution. The diameter of the prepared fibers is in the range of microns, submicrons, and nanometers; the prepared fiber membrane materials have a large specific surface area, high porosity, and shape. The appearance and size can be adjusted, and in recent years,...
