Abstract

The invention discloses a production method of environment-friendly PU metal leatherette paper. The production method comprises selecting original leatherette backing paper, impregnating, prime-coating, topcoating and embossing; the topcoating uses a comma knife coating manner, and a top coating is evenly coated on the prime-coated paper, wherein the top coating comprises a waterborne gold-silver powder and a waterborne PU resin, the waterborne gold-silver powder in the top coating accounts for 15-20% of the total dry component of the top coating, the topcoating amount is 5-7g / m<2>, the drying temperature is 130-140 DEG C, and the lathing speed is 35-50m / min. The production method is low in cost, the surface of the prepared leatherette paper has a leather texture, is soft and loose and can be randomly folded, the leatherette paper also shows a strong metal and heavy impression and is high in grade, and the gloss is attractive.

Description

technical field [0001] The invention relates to the technical field of leather-filled paper production, in particular to a production method of environment-friendly PU metal leather-filled paper. Background technique [0002] With the development of papermaking technology and subsequent paper deep processing, paper plays an increasingly important role in the packaging industry. The packaging paper also varies greatly with the grades of products, and the materials used are also quite different. [0003] Ordinary packages such as fruits, vegetables, aquatic products, etc. are only packaged with cheap cardboard and gray-bottomed whiteboard; household appliances and other products are generally packaged with kraft cardboard; high-end underwear and apparel are packaged with single-sided printed whiteboard. Packaging; the packaging paper for high-end watches, notebooks, stationery, gold and silver jewelry, etc. is made of luxury packaging paper such as high-grade leather-filled p...
