Description
Technical field
The present invention relates to the production method of a kind of Synthetic Leather, in particular to the production method of a kind of high-permeability Synthetic Leather.
Background technology
Along with improving constantly of standard of living, saturating cigarette, the permeability of the furniture such as sofa are required more and more higher by people. At present, Synthetic Leather its preparation method is mainly divided into two classes:
(1) dry method:
Synthetic leather dry production is coated in the separate-type paper of various lines with urethane resin (PU), undertaken by base material of base cloth (looped fabric, non-woven fabrics etc.) after drying, upper paste fitting, the processing procedure such as oven dry, then through printing treatment so that it is in sense of touch, toughness and in appearance, is enough to the corium that matches in excellence or beauty.
(2) wet method:
The method comprises the steps: first uniform fold one layer of PU resin on textile fibres cloth, being immersed by the textile fibres cloth being coated with PU resin is equipped with in the coagulating pan of water again, when PU resin layer is in half curdled appearance, the mould utilizing surface to be carved with pattern carries out embossing process on PU resin layer, then textile fibres cloth is taken out, enter in washing bath so that it is slaking is shaping further, namely obtains the PU synthetic leather that surface has solid pattern.
Although adopting wet method can obtain having the synthetic leather of ventilation property, water vapour permeability, continuous poriferous Rotating fields, but the cycle of wet-layer preparation is longer. The present invention adopts dry method preparation to have excellent urethane resin synthetic leather ventilative, smoke performance thoroughly, solves traditional PU and removes from office air-locked technical problem, and its production cost is low, is convenient to control.
Summary of the invention
It is an object of the invention to provide the production method of a kind of high-permeability upholstery leather, for achieving the above object, present invention employs following technical scheme:
A production method for high-permeability upholstery leather, comprises the steps:
(1) separate-type paper is selected, at described separate-type paper surface evenly coating urethane surface layer slurry, skin film namely obtained to be transferred after oven dry; Selecting raising base cloth, the matte in described raising base cloth is evenly coated with polyurethane sticking layer slurry, after the bonding coat laminating on described skin film and described base cloth being dried, separate-type paper is peeled off and obtains dry method work in-process; The weight of described polyurethane sticking layer slurry and urethane surface layer slurry consists of:

| Tensio-active agent | 0.2-0.5 part |
| Antiwear assistant | 0.5-1.0 part |
| Mill base | 10-15 part |
(2) gained work in-process in step (1) being carried out rear section processing treatment, be coated with, at described half-finished surface layer, the polyether resin slurry that degree of crosslinking is 80%, after oven dry, its surface carried out decorative pattern sizing, the weight of described polyether resin slurry consists of:
Urethane resin 40 parts
Solvent 40-60 part
(3) by step (2) through after half-finished back side of section processing treatment and the matte of one side nylon loop carry out adhesion process by viscose glue mixed solution, get product in 120-140 DEG C of baking and curing.
Solvent described in step (1) is one or both the combination any in dimethyl formamide, butanone.
The weight of the viscose glue mixed solution described in step (3) consists of:
| Polyurethane composite gel | 100 parts |
| Diamine type solidifying agent | 15-20 part |
