Abstract

The invention discloses a method for manufacturing suede polyurethane synthetic leather with high physical properties. Including the preparation of synthetic leather semi-finished products, sanding treatment and napping treatment: the preparation of synthetic leather semi-finished products is to apply polyurethane foam slurry to the base fabric, and then dry in an oven; sanding treatment is to complete the foaming process of synthetic leather The surface of the semi-finished product is first ground with a multi-roller grinding wheel, and the amount of grinding is adjusted by selecting the sandpaper and the speed of the grinding wheel; the napping treatment is to use the carbon fiber napping roller to roughen the leather surface after the sanding treatment. The high physical property suede polyurethane synthetic leather of the present invention has a simple manufacturing method, directly coats the base cloth, reduces the traditional wet process, greatly improves the production efficiency, and effectively reduces the cost of materials and energy consumption.

Description

technical field [0001] The invention relates to a method for manufacturing polyurethane synthetic leather, in particular to a method for manufacturing high-property suede polyurethane synthetic leather. Background technique [0002] Polyurethane synthetic leather (PU synthetic leather) is a kind of artificial synthetic leather that uses various cloth bases as substrates, and coats polyurethane resin on the substrates to impart various patterns and patterns. In order to imitate the suede effect of the surface of the leather split leather, the traditional manufacturing methods usually include: first make the wet base, and then perform secondary processing on the back of the wet base: flocking, planting leather powder, and foaming of sheepbucks Etc., and then grind the crust leather to achieve a velvet effect similar to genuine leather. The imitation leather suede synthetic leather manufactured by traditional technology has a long process, complex equipment, high energy consum...
