The invention discloses a preparation method of waterborne polyurethane synthetic leather Bayse and applications of the waterborne polyurethane synthetic leather Bayse, belonging to the technical fields of the synthetic leather and the preparation method. The preparation method comprises the following steps: (1) preparing a bottom cloth; (2) impregnating the bottom cloth, wherein, the impregnation prescription contains the following components in parts by weight: 100 parts of water and 1-10 parts of metal nitrade, and the liquid rate of the impregnated bottom cloth is 10-30%; (3) heating, ironing, pressing, polishing and baking the bottom cloth after impregnating; (4) coating a waterborne polyurethane foaming layer on the bottom cloth after baking; (5) obtaining the synthetic leather Bayse after common baking, pressing and polishing. According to the preparation method, the defects of fussy operation, heavy pollution and drying difficulty in the existing preparation process of the waterborne polyurethane synthetic leather Bayse are overcome; one-time impregnation prescription and process, which are free of pollution, low in liquid rate after impregnation, and easy to bake are provided; meanwhile, a synthetic leather product taking the waterborne polyurethane synthetic leather Bayse as a base cloth is also provided; the preparation method is high in efficiency, and the obtained product is good in performance.

The invention provides a preparation method of an ultraviolet-proof coating. The preparation method comprises the following steps of: (1) adding 4 to 12% of nanometer titania, 0.5 to 2% of talcum powder and 2 to 6% of benzotriazole to a stirrer, and uniformly stirring; (2) adding proper acetone to the mixture in step (1), and uniformly dispersing; (3) adding 5 to 15% of polyethylene glycol to the mixture in step (2); and (4) compensating the acetone until reaching 100%, and uniformly stirring so as to obtain the finished product of the ultraviolet-proof coating. By adopting the ultraviolet-proof coating prepared by the preparation method provided by the invention, the fabric can be processed without greatly changing the original hand feel, and the ultraviolet transmittance of the fabric is below 8%.

The invention discloses a leather coating and lustering agent and a preparation method thereof. The leather coating and lustering agent is prepared from raw materials in percentage by mass as follows:0.1%-2% of organosilicone modified acrylic resin, 1%-10% of a lustering component, 1%-3% of a hydrophobic component, 3%-7% of a volatile component, 1%-2% of a wetting agent, 0.1%-1% of a thickening agent, 0.3%-0.7% of a corrosion remover and the balance of water. The components are mixed uniformly in batches, and the leather coating and lustering agent can be obtained. The formula of the leathercoating and lustering agent is safe and environmentally friendly, the preparation method is simple and low in production cost, the leather coating and lustering agent has no corrosion effect on leather, a transparent flexible coating layer can be formed on the leather surface after the agent is sprayed on the leather surface and the leather is slightly wiped by a towel, the hand feeling of the leather surface cannot be affected by the coating layer, the coating layer is high in stability and good in durability, and the leather coating and lustering agent can realize lustering, waterproof, anti-pollution and anti-aging functions for a long time.

The invention discloses an ultraviolet-proof coating. The ultraviolet-proof coating comprises the following components in percentage by weight: 4-12% of nanometer titanium dioxide, 0.5-2% of talcum powder, 5-15% of polyethylene glycol, 2-6% of benzotriazole and the balance of acetone. The ultraviolet-proof coating provided by the invention does not remarkably change the hand feeling of the fabric when being used for treating the fabric, and enables the ultraviolet transmission rate to be lower than 8%.
