Abstract

The invention discloses a PU automobile leather easy to clean and a preparation method thereof. The PU automobile leather easy to clean comprises a base cloth, a bonding layer, a middle layer, a surface layer, a first surface layer and a second surface layer which are arranged in sequence; the first surface layer comprises the following components of 5-95 parts of hydrophobic aliphatic self-matting polycarbonate polyurethane, 5-95 parts of hydrophobic aliphatic polyurethane gloss surface treatment agent, 0.5-8 parts of isocyanate cross-linking agent, 3-8 parts of silane coupling agent, 0.1-2 parts of leveling agent and 1.1-15 parts of other auxiliaries in parts by weight; the total amount of the hydrophobic aliphatic polyurethane gloss surface treatment agent and the hydrophobic aliphaticself-matting polycarbonate polyurethane is 100 parts; the second surface layer comprises the following components of 40-75 parts of side-chain fluorine-containing vinyl silicone resin, 2-25 parts of polysilazane, 3-20 parts of hydrogen containing silicone oil, 30-70 parts of organic solvents, 0.5-18 parts of adhesive agent, 0.001-1 parts of platinum catalyst, 0.5-10 parts of accelerator, 8-40 parts of packing and 0.1-2 parts of wear-resistant agent in parts by weight. The PU automobile leather easy to clean has the advantages that the PU automobile leather easy to clean is easy to clean, and meanwhile, the PU automobile leather easy to clean possesses excellent hydrolysis resistance, wear resistance and weather resistance.

Description

technical field [0001] The invention relates to the field of automobile leather, more specifically, it relates to an easy-to-clean PU automobile leather. Background technique [0002] PU synthetic leather is an ideal substitute for natural leather. It is widely used in the interior decoration of vehicles. It has excellent breathability and aging resistance, and it feels softer than real leather and has strong flexibility. [0003] The publication number is CN103129067A, and the publication date is June 5, 2013. The Chinese invention discloses a kind of PU synthetic leather, which includes a base cloth layer. The upper surface of the base cloth layer is provided with a PU resin layer, and the lower surface is coated with a polyurethane resin layer. A first adhesive layer and a second adhesive layer are arranged between the base cloth layer and the polyurethane resin layer and the PU resin layer respectively. [0004] In the above-mentioned prior art, the surface layer of the...
