Abstract

The invention discloses a formula of hydrolysis-resistant waterborne polyurethane artificial leather and a method for manufacturing the same and relates to waterborne polyurethane adhered with ultrafine fiber base. The method comprises the following steps of: preparing surface material resin solution and bottom material resin solution according to a formula proportion by adopting hydrolysis-resistant and cold-resistant waterborne PU resin, standing the solution for defoaming; opening release paper, coating surface material resin on the release paper, sending the release paper to an oven for drying, and winding; and opening the release paper coated with the surface layer, coating bottom material resin on the release paper, sending the release paper to the oven again until the release paper is semi-dried, rapidly adhering the ultrafine fiber base with the release paper, performing roll extrusion and drying, and finally winding and packaging.

Description

Technical field: [0001] The invention relates to a hydrolysis-resistant water-based artificial leather and a manufacturing method thereof, in particular to a water-based polyurethane bonded with a superfine fiber base. Background technique: [0002] Artificial leather made of polyurethane resin can be used in various fields such as furniture, clothing, luggage, shoes, and automobiles. Due to the strong polarity of the traditional polyurethane resin, a strong solvent is needed to dissolve it for convenient construction, so it causes great harm to the environment. The commonly used solvent is DMF, which is a toxic chemical that seriously damages human liver organs, which poses a serious threat to the health of workers in tanneries. Invention content: [0003] The purpose of the present invention is to provide a hydrolysis-resistant water-based polyurethane artificial leather formula and its manufacturing method. It has the characteristics of hydrolysis resistance and cold r...
