Description
Technical field
The present invention relates to a kind of manufacture method of Synthetic Leather, a kind of manufacture method with fireproof sofa artificial leather of functions such as anti-flammability, ageing-resistant, weatherability, environmental protection.
Background technology
Synthetic Leather (PU synthetic leather) is a coated polyurethane resin and give various patterns or concavo-convex decorative pattern and the real leather intimating synthetic leather made is used for substituting corium on cloth matter base material.The PU sofa artificial leather is one of important kind of PU leather.Chinese patent 02135394.8 has been introduced a kind of preparation method of superfine fiber sofa leatherette, selects for use superfine fibre nonwoven cloth to make base cloth, to improve the rerum natura of sofa artificial leather.Chinese patent 03111848.8 has been introduced a kind of Bundle-like ultrafine fibre polyurethane sofa leather and its production method, and the nonwoven fabric made from bundle superfine fibre is a base cloth, improves the tearing strength and the peel strength of sofa artificial leather.In the above-mentioned document functions such as fire-retardant, the environmental protection of base cloth are not done requirement.Along with the high speed development of PU synthetic leather industry, when the rerum natura to sofa claims, increased the requirement of anti-flammability to the PU sofa artificial leather, weatherability, environmental protection, abrasion performance etc.
Summary of the invention
The present invention is intended to propose a kind of manufacture method with sofa artificial leather of anti-flammability, environmental protection, a kind of manufacture method of fireproof sofa artificial leather.
The manufacture method of this fireproof sofa artificial leather comprises that (a) uses the wet coating layer of polyurethane on base cloth, obtains PU wet method base material; (b) use the bonding polyurethane surface layer of dry method on PU wet method base material, that is: be coated with one deck top and be coated with slurry as surface layer on release liners, oven dry is coated with one deck primary coat slurry again as tack coat, fit with PU wet method base material then, and oven dry, maturation, wherein:
(1), base cloth adopts common double suede base cloth;
(2), the polyurethane resin in (a) step adopts polyethers and poly-carbon type polyurethane resin, and add phosphorus flame retardant in the wet method slurry;
(3), the polyurethane resin in (b) step adopts poly-carbon type resin, the aliphatic resin of surface layer wherein, the aromatic resin of tack coat, and add phosphorus flame retardant in the top is coated with two kinds of dry method slurries with primary coat;
(4), dipping tank that the manufactured goods of (b) step gained are put into the aqueous, environmental protective retardant solution floods, and makes finished product after the drying again.
The present invention is by selecting polyethers, poly-carbon type polyurethane resin for use, add phosphorus flame retardant and with the method for base cloth by flooding in the environmental protection flame retardant agent solution, make the PU synthetic leather have good fire-proof function and ageing-resistant, anti-wear performance in polyurethane resin.When adopting the dipping retardant solution to make base cloth reach fire-retardant the requirement in (4) step, the anti-flammability of the resin of cortex also further strengthens, and because of synthetic leather in dipping process through flooding repeatedly and pushing, solvent composition residual in the synthetic leather is reduced, thus environmental protection more.
