Abstract

The present invention discloses a production method of hydrolysis resistance regenerating resin synthetic leather, including: stirring uniformly and filtering dimethylformamide and wet hydrolysis resistance paste; adding a mixture of dimethylformamide, a wet hydrolysis resistance additive and a surfactant and stirring uniformly, adding wet high hydrolysis resistance regeneration polyurethane resin to mix uniformly, filtering and defoaming to get a coating; stirring the dimethylformamide and the high hydrolysis resistance regeneration polyurethane resin uniformly and then adding the mixture of the surfactant, dimethylformamide and the wet hydrolysis resistance paste to stir uniformly to get an immersion liquid, feeding non-woven fabrics in the immersion liquid and then feeding into a quantitative roll, scraping the coating, solidifying to be film, extruding and washing, drying and fixing the shape, processing the color to get the wet base, uniformly scraping the high hydrolysis resistance dry polyurethane resin, dimethylformamide, toluene, butanone, dry hydrolysis resistance paste and the surfactant on release paper, and adhering the wet base to get the product. The synthetic leather of the present invention is soft in hand feel, good in flexibility, good in touch sense, and high in peel strength.

Description

technical field [0001] The invention relates to a manufacturing method of artificial leather, in particular to a manufacturing method of hydrolysis-resistant regenerated resin synthetic leather. Background technique [0002] Ordinary synthetic leather feels hard, has poor elasticity, is prone to peeling and other phenomena, and is difficult to decompose after damage, which is likely to cause environmental pollution and high production costs. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for producing hydrolysis-resistant regenerated resin synthetic leather. The method for producing hydrolysis-resistant regenerated resin synthetic leather has a simple process, and the produced product has soft hand feeling, excellent elasticity, high peel strength, and good touch. Low cost, high physical properties, and environmental protection. [0004] The technical scheme that the present invention adopts in ...
