Problems solved by technology

[0003] Ponchos facilitate people's lives, and sales are increasing day by day, but the development of ponchos cannot stand still
For the acid corrosion caused by rainwater and the aging of materials caused by sunlight, not only will it emit an unpleasant smell, but it will also cause a sudden drop in service life

Abstract

The invention relates to the technical field of new materials, and discloses a durable hydrophobic rain cape. An organic-inorganic hybrid nano-composite material with outstanding acid corrosion resistance and aging performance is prepared by using an inorganic nano material to modify organic resin and utilizing the size effect of nanoparticles. A prepared coating still has excellent coating adhesion in a 30-week ultraviolet accelerated aging test, the surface has no cracks, wear resistance and ultraviolet resistance are excellent, and the coating can resist the erosion of acidic rain and has good surface hydrophobicity. No odor is generated after use, and the life of the rain cape can be prolonged by 2-3 years.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a durable waterproof rain cape. Background technique [0002] The rain cape is a product produced by the extension of the raincoat. It is a rainproof clothing made of waterproof fabric, open and without sleeves. The waterproof fabrics suitable for ponchos include tapes, tarpaulins and plastic films. Modern poncho waterproof fabrics focus on breathability, commonly used such as special nylon and Gore-Tex. According to the functional style, it can be divided into walking rain capes, bicycle rain capes, single electric car rain capes, double electric car rain capes, motorcycle rain capes, disposable rain capes, special rain capes for children, helmet rain capes, etc. [0003] Ponchos facilitate people's lives, and sales are increasing day by day, but the development of ponchos cannot stand still. Acid erosion caused by rainwater and material aging caused by sunl...
