High-pressure-resistant water-base foamed raincoat leather

Abstract

The invention discloses high-pressure-resistant water-base foamed raincoat leather. The raincoat leather comprises base cloth and a high-pressure-resistant resin layer coating one surface of the base cloth, wherein high-pressure-resistant resin layer comprises a water-based PU bottom layer, a water-based foamed resin intermediate layer, a water-based resin upper layer and an anti-UV water-based resin surface layer which are sequentially connected from bottom to top. According to the high-pressure-resistant water-based foamed raincoat leather, a waterproof gas-permeable surface layer is a four-layer structure formed by the water-based PU bottom layer, the water-based foamed resin intermediate layer, the water-based resin upper layer and the anti-UV water-based resin surface layer, is safe and environmentally friendly and has bending resistance, high softness and tensile strength and relative high gas permeability and water resistance; the water-base foamed resin intermediate layer is of a hollow formed structure and is light, so that the leather feel and the water pressure resistance are provided; by adding a mixture of nano-TiO2 powder and nano-ZnO powder to the surface layer, the foamed raincoat leather has the effects of resisting ultraviolet light, protecting leather, blocking sunshine and resisting ageing, and the service life is prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of raincoat synthetic leather, in particular to a high-pressure-resistant water-based foamed raincoat leather. 【Background technique】 [0002] 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. [0003] 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. Water-based...
