Abstract

The invention discloses a method for producing synthetic leather with high transparency, which is characterized in that it comprises the following steps: mixing polyurethane resin, high-solid acrylic modified polyurethane resin, methyl ethyl ketone, HDI trimer curing agent, and bismuth isooctanoate accelerator Stir evenly in proportion to form a colorless and highly transparent slurry. The colorless and highly transparent slurry is coated on the surface of the polyurethane synthetic leather by printing, and the coating amount is controlled at 50-90g / m2. The drying temperature is controlled at 110~140°C, and the drying time is controlled at 3~5 minutes. The highly transparent polyurethane synthetic leather of the present invention has high transparency, strong crystal sense and clear texture, and the polyurethane synthetic leather of the present invention has low preparation cost, simple production operation and high efficiency.

Description

technical field [0001] The invention relates to a polyurethane synthetic leather, more specifically to a highly transparent polyurethane synthetic leather product and a manufacturing method thereof. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future. Synthetic leather has been widely used in the production of luggage, clothing, footwear, furniture and other products. But at the same time, with the development of social economy and the improvement of people's living standards, the requirements for the added value of these daily necessities are also getting higher and higher. At present, the processes with high transparency effect include moisture curing and secondary veneer processes. Moisture-curing products are prone to fogging, darkening of gloss, and intolerance to yellowing; while products with secondary veneering technology can solve such problems, but the cost is too high and the production operatio...
