Abstract

The invention provides a production method for leather-like paper. The leather-like paper comprises, from bottom to top, a white board layer, a carboxylic butadiene-styrene latex layer and a polyurethane synthetic leather layer. According to the method, a white board is used as a bottom layer and coated with carboxylic butadiene-styrene latex; a carboxylic butadiene-styrene latex coating is heated and dried so as to form a film; the obtained carboxylic butadiene-styrene latex film is coated with polyurethane synthetic leather slurry; and a polyurethane synthetic leather slurry coating is dried so as to obtain the leather-like paper. The leather-like paper provided by the invention uses the white board easily available on a common market as the bottom layer; the carboxylic butadiene-styrene latex coats the white board at first, and the carboxylic butadiene-styrene latex film obtained after drying functions as a bridge; the carboxylic butadiene-styrene latex has high bonding force with the surface of the white board and with polyurethane synthetic leather, so the white board, the carboxylic butadiene-styrene latex film and polyurethane form a firm bonded body; and the carboxylic butadiene-styrene latex film and polyurethane can protect a printed pattern and improve hardness and rub resistance, enable the touch of leather to be obtained, enhance the beauty of the leather-like paper and elevate the comfort level of the leather-like paper in usage.

Description

technical field [0001] The invention relates to a production method of leather-like paper, which belongs to the technical field of packaging materials. Background technique [0002] Imitation leather paper, is a washable, printable, printable, laminated, coated, silk-screened low-carbon environmentally friendly material, it feels comfortable, close to leather, is an ideal material for the interior or exterior of the product, widely used in Clothing signs, tags, leather tags, business cards, high-end leather bags, belts, top hats, handbags, notepad covers, shoe materials, high-end product decoration, stationery, artwork packaging and other fields. Existing imitation leather paper usually directly coats slurry such as one deck polyurethane synthetic leather on some special papers, forms polyurethane synthetic leather layer (polyurethane synthetic leather is polymerized by isocyanate (monomer) and hydroxyl compound, to simultaneously Adding plasticizers, tackifiers, antifungal...
