Polyurethane synthetic leather material with antibacterial and mildewproof functions and preparation method of polyurethane synthetic leather material

Abstract

The invention discloses a polyurethane synthetic leather material with antibacterial and mildewproof functions. The polyurethane synthetic leather material comprises a synthetic leather main body, wherein inner silk layers and PI film layers are respectively arranged on both sides of the synthetic leather main body; and the synthetic leather main body is prepared from amino-acid resin. By the arrangement of the PI film layers, a PI solution turns into a PI film when being solidified, and the synthetic leather main body and the PI film are integrated; furthermore, the PI film is high in low andhigh-temperature resistance, electrical insulation property, radiation resistance and medium resistance, so that the prepared synthetic leather material can be applied to any severe conditions, and the application range of the synthesis leather is greatly expanded; and by the arrangement of the inner silk layers, the chemical structure of a silk fiber is completely consistent with 18 amino acidsin the human skin, when the human skin is in contact with the fabric, people feel just like the own skin according to a similarly compatible theory, so that the moisture absorption property, the breathability, the comfort and the softness of the material which is in contact with the skin are greatly improved.

Description

technical field [0001] The invention relates to a polyurethane synthetic leather material and a preparation method thereof, in particular to a polyurethane synthetic leather material with antibacterial and antifungal functions and a preparation method thereof. Background technique [0002] Polyurethane synthetic leather is a kind of polymer material with special properties. It has outstanding properties such as outstanding wear resistance, strength and toughness, solvent resistance, oil resistance, and high cutting rate. In 1953, Germany first applied for a patent for polyurethane synthetic leather, and commercial production began in the 1960s. At present, polyurethane synthetic leather materials are widely used in sports and leisure shoes, leather shoes, leather clothing, bags, sofa furniture, belts, ticket holders, stationery, automotive interiors and medical equipment manufacturing and other fields. Since my country first introduced the dry process production technology ...
