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:
The present invention relates to extremely manufacture method of a kind of hydrolysis-resistant waterborne artificial leather, especially relate to the aqueous polyurethane of a kind of superfine fibre base that fits.
Background technology:
The artificial leather that utilizes polyurethane resin to make can be used in every field such as furniture, clothes, case and bag, footwear, automobiles.Because traditional polyurethane resin polarity is very strong, need strong solvent it could be dissolved with convenient construction, so environment is caused very big harm.Solvent commonly used is DMF, is a kind of poisonous chemicals, grievous injury people's liver organ, and this constitutes a serious threat for the healthy of workman of tannery.
Summary of the invention:
The purpose of this invention is to provide a kind of formula of hydrolysis-resistant waterborne polyurethane artificial leather and manufacture method thereof, it has hydrolysis and cold-resistant characteristics, can reach-20 ℃ of following 80,000 crackless effects, and rerum natura can reach the standard identical with common synthetic leather.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: adopt the cold-resistant water-based PU resin of a kind of hydrolysis, prepare fabric resin solution and bed material resin solution, standing and defoaming by formula rate.After release liners opened, at first fabric resin is coated on the release liners, sends into oven for drying, rolling then.Once more the release liners of coated surface layer is opened, with bed material resin-coated on, send into baking oven once more, till half-dried, rapidly will super fine base and its applying, and carry out roll extrusion, oven dry, last rolling, packing.
The prescription of described fabric resin solution is: 100 parts of waterborne polyurethane resins, deionized water 0-50 part, thickener 0.1-2 part, levelling agent 0.1-2 part, fluorine modifier 0.1-2 part, color 1-10 part, defoamer 0-5 part; The prescription of described bed material resin solution is: 100 parts of waterborne polyurethane resins, deionized water 0-50 part, thickener 0.1-2 part, color 1-10 part, defoamer 0-5 part.
Preparation process: 1, configuration lining resin solution and bed material resin solution; 2, select the burnishing surface of fabricbase as being coated with charge level; 3, select the release liners of suitable decorative pattern; 4, extension is coated with water-based PU lining on release liners; 5, oven dry lining, temperature is about 125 ℃; 6, hang primer; 7, the oven dry bed material is fitted to half-dried; 8, oven dry artificial leather, rolling, packing.
The present invention has following beneficial effect: soak in 10%NaOH after 24 hours, the surface is flawless; Cold tolerance is good.80,000 folding flawlesses under-20 ℃ of conditions; The adhesion strength height.Peel strength can reach 100N/2.5cm.
The specific embodiment:
This specific embodiment is by the following technical solutions: adopt the cold-resistant water-based PU resin of a kind of hydrolysis, prepare fabric resin solution and bed material resin solution, standing and defoaming by formula rate.After release liners opened, at first fabric resin is coated on the release liners, sends into oven for drying, rolling then.Once more the release liners of coated surface layer is opened, with bed material resin-coated on, send into baking oven once more, till half-dried, rapidly will super fine base and its applying, and carry out roll extrusion, oven dry, last rolling, packing.
The prescription of described fabric resin solution is: 100 parts of waterborne polyurethane resins, 10 parts of deionized waters, 1.2 parts of thickeners, 0.5 part of levelling agent, 0.2 part of fluorine modifier, 5 parts of colors, 0.5 part of defoamer; The prescription of described bed material resin solution is: 100 parts of waterborne polyurethane resins, 20 parts of deionized waters, 2 parts of thickeners, 5 parts of colors, 0.5 part of defoamer.
Preparation process: 1, configuration lining resin solution and bed material resin solution; 2, select the burnishing surface of fabricbase as being coated with charge level; 3, select the release liners of suitable decorative pattern; 4, extension is coated with water-based PU lining on release liners; 5, oven dry lining, temperature is about 125 ℃; 6, hang primer; 7, the oven dry bed material is fitted to half-dried; 8, oven dry artificial leather, rolling, packing.
This specific embodiment is soaked 24 hours in 10%NaOH after, the surface is flawless; Cold tolerance is good.80,000 folding flawlesses under-20 ℃ of conditions; The adhesion strength height.Peel strength can reach 100N/2.5cm.
The specific embodiment two: be that with the specific embodiment one difference deionized water in the prescription of described bed material resin solution is that 20 parts, thickener are 1.5 parts; Other compositions are all identical with the specific embodiment one with prescription.
