Anti-ultraviolet thin waterborne raincoat leather

Abstract

The invention discloses an anti-ultraviolet thin waterborne raincoat leather. The anti-ultraviolet thin waterborne raincoat leather comprises a base fabric and a waterborne resin attaching layer. One face of the base fabric is attached to the waterborne resin attaching layer, the waterborne resin attaching layer is of three hierarchical structures, the bottom layer is a waterborne PU bonding layer, the middle layer is a waterborne resin reinforced layer, the surface layer is an anti-ultraviolet waterborne resin layer, the other face of the waterborne PU bonding layer and one face of the base fabric are bonded, the thickness of the waterborne resin attaching layer ranges from 0.1 mm to 0.25 mm, and the whole thickness of the base fabric and the waterborne resin attaching layer is 0.2 mm to 0.65 mm. In the anti-ultraviolet thin waterborne raincoat leather, as the thin waterborne resin attaching layer is made from waterborne polyurethane serving as raw materials, the anti-ultraviolet thin waterborne raincoat leather is safe, environmentally friendly, soft and comfortable; waterborne epoxy resin is used as a curing agent, the peeling strength is high, and the water pressure resistance is good; as nanometer TiO2 powder, nanometer ZnO powder and nanometer China-hemp powder are added into the anti-ultraviolet waterborne resin layer of the surface layer, the high anti-ultraviolet performance is achieved, the whole anti-aging performance of the raincoat leather is improved, and the service life of the raincoat leather is prolonged.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of raincoat synthetic leather, in particular to an anti-ultraviolet thin water-based raincoat leather. [0003] 【Background technique】 [0004] A raincoat is rain clothing made of waterproof fabric. The waterproof fabrics suitable for raincoats include tapes, tarpaulins and plastic films. With the development of technology, the current raincoats are also developing in the direction of good air permeability, multi-functionality, environmental protection and better wearing comfort. [0005] At present, most raincoats still use PVC leather, which has poor air permeability, poor bending resistance, softness, and tensile strength, and hard hand feeling. PVC raincoat leather is easy to age after being used for a long time, non-degradable, toxic, and exists impact on environmental pollution. In particular, police raincoats require high water pressure resistance when working outdoors for a long time. Wate...
