Abstract

The invention discloses nanometer synthetic leather which comprises the following components: 80-99% of synthetic leather raw material and 1-20% of nanometer powder, wherein the nanometer powder is the mixture of nanometer silver and nanometer silicon dioxide. Through adding the nanometer materials in the synthetic leather, the invention not only keeps the original physical property of the common synthetic leather, but also greatly strengthens the abrasion resistance of the synthetic leather, protects the environment and prevents the bacteria, greatly prolongs the service life of the product, brings good glossiness without fading, and ensures that the cleaning is convenient.

Description

technical field [0001] The invention relates to a new material used in the field of clothing and home decoration, in particular to a nano-synthetic leather. Background technique [0002] Synthetic leather is made by mixing PU pulp with genuine leather fibers and is widely used. Synthetic leather is used in many fields such as clothing and home decoration. Its coating is soft and elastic, with good coating strength and can be used for very thin coatings. The coating is moisture-permeable and air-permeable, in addition to being relatively dry-cleaning resistant. Under the same hardness, it has higher load-bearing capacity than other elastomers, high impact resistance, wide rebound range, suitable for high-frequency flexural applications, and good low-temperature flexibility. Synthetic leather is resistant to ozone erosion, resistant to radiation, and can be made into flame-retardant materials. Synthetic leather can be bonded with wood, metal and most plastics, and can be ma...
