Problems solved by technology

With the improvement of people's requirements for the grade and quality of daily products, synthetic leather with a single performance can no longer meet the needs of consumers, and synthetic leather with good waterproof and antifouling functions is favored by consumers. Fabric sofa leather has various colors, but it is not waterproof and stain-proof, and it is inconvenient to clean
Synthetic leather with a velvet feel is rare, and most of them are made of yangbuck foaming resin, but the process is difficult to control and the cost is high. Some of them have a velvet effect by transferring the velvet release paper, but the velvet effect is not strong. Therefore develop a kind of suede three proof sofa furniture polyurethane synthetic leather has broad market prospect

Embodiment 1

[0031] A method for preparing polyurethane synthetic leather for suede three-proof sofa furniture, comprising the following steps:

[0032] (1) Prepare wet-process polyurethane slurry as impregnating slurry, with the raised surface of the single-faced fleece substrate facing up, and the thickness of the single-faced fleece substrate is 0.65mm. After impregnating the single-faced fleece substrate, pass through The DMF solution is coagulated, washed with water, and dried to obtain a wet-process semi-finished product with a thickness of 1.0mm, which is denoted as S0; wherein, the wet-process polyurethane slurry is prepared by parts by weight from the following components:

[0033]

[0034] (2) Use a roller-type dermabrasion machine to sand the surface of the wet-process semi-finished product to obtain a semi-finished product with a velvet feel. The sandpaper used for the sanding is 240 mesh, and the smooth wool and the reverse wool are sanded once, and the wool feels after sand...

Embodiment 2

[0051] A method for preparing polyurethane synthetic leather for suede three-proof sofa furniture, comprising the following steps:

[0052](1) Prepare the wet-process polyurethane 3 urethane slurry as the impregnating slurry, with the raised side of the single-face fleece substrate facing up, and the thickness of the single-face fleece substrate is 1.0 mm. After impregnating the single-face fleece substrate , followed by DMF solution coagulation, washing, and drying to obtain a wet-process semi-finished product with a thickness of 1.3 mm; wherein, the wet-process polyurethane slurry is prepared from the following components by weight:

[0053]

[0054] (2) Use a roller-type dermabrasion machine to sand the surface of the wet-process semi-finished product to obtain a semi-finished product with a velvet feel. The sandpaper used for the sanding is 200 mesh, and the smooth wool and the reverse wool are sanded once, and the wool feels after sanding. The thickness of the semi-fin...

Embodiment 3

[0061] A preparation method of polyurethane synthetic leather for suede three-proof sofa furniture, comprising the following steps:

[0062] (1) Prepare the wet-process polyurethane slurry as the impregnating slurry. The raised surface of the single-faced fleece substrate faces up, and the thickness of the single-faced fleece substrate is 0.75mm. After impregnating the single-faced fleece substrate, it is passed through The DMF solution is coagulated, washed with water, and dried to obtain a wet-process semi-finished product with a thickness of 1.2mm; wherein, the wet-process polyurethane slurry is prepared from the following components by weight:

[0063]

[0064] (2) Use a roller-type dermabrasion machine to sand the surface of the wet-process semi-finished product to obtain a semi-finished product with a velvet feel. The sandpaper used for the sanding is 180 mesh, and the smooth hair and the reverse wool are sanded once, and the wool feels after sanding. The thickness of...

Abstract

The invention discloses suede three-prevention polyurethane leather for sofa furniture and a preparing method thereof. The method includes the following steps of preparing wet-method polyurethane slurry as impregnation slurry, conducting impregnation treatment on a single-side suede base material to obtain a wet-method semi-fished product, conducting sanding treatment on the surface of the wet-method semi-finished product to prepare a suede semi-finished product, preparing a printing material, conducting printing treatment on the suede semi-finished product to obtain suede leather with a stereoscopic pattern, and spray-coating the suede leather with an organic fluosilicic waterproof material to prepare the final product. The organic fluosilicic waterproof material in the polyurethane leather is a fluorine-containing organic silicon material; the organic fluosilicic waterproof material has a synergistic effect with a closed type isocyanate crosslinking agent and has a crosslinking effect with base fabric fiber and polyurethane resin after being dried, the solvent resistance, ageing resistance and dirt resistance of the product are improved, and the final product gives a high suede impression, has an appearance exactly like fabrics, is smooth in internal handfeel, natural in color and luster and excellent in tactile impression and has a real-leather-like effect.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather preparation, and in particular relates to a suede three-proof polyurethane synthetic leather for sofa furniture and a preparation method thereof. Background technique [0002] Polyurethane synthetic leather is a kind of imitation leather synthetic leather with various base fabrics as base materials, coated with polyurethane resin to make it have various patterns, patterns, functions and handles.
