| titleOfInvention | Manufacturing process of high-solid hydrophilic water-dispersive polyurethane resin for textile coating and vapor-permeable waterproof fabric used it |
| abstract | The present invention relates to a method for preparing a high solid hydrophilic water-dispersible polyurethane resin for textile coating and a moisture-permeable waterproof fabric using the same, wherein the method for producing a high solid hydrophilic water-dispersible polyurethane resin includes a weight average molecular weight of 1,000 to 3,000. Ether polyol (a) 4 to 8 wt%, reactive silicone (b) 1.5 to 3.0 wt% with a weight average molecular weight of 1,000 to 3,000, hydrophilic polyether polyol (c) 4 to 8 wt%, chain extender (d) 0.4 A first step of preparing a prepolymer by reacting in a ratio of ~ 1.4% by weight, 1.0 ~ 1.9% by weight of dispersant (e), and 5.0 ~ 8.7% by weight of diisocyanate (f); An emulsifying aid reacted in a ratio of polyether polyol (g) 15.2 to 28.3% by weight, diisocyanate (h) 2.3 to 4.4% by weight, and hydrophilic polyether polyol (i) 6.13 to 11.4% by weight in the range of 2,000 to 4,000 by weight average molecular weight A second step of dispersing the prepolymer in 13 to 25% by weight of water, and then mixing the prepared prepolymer and kneading at high speed to prepare a prepolymer dispersion; To the prepared prepolymer dispersion, a polyether amine (j) having a molecular weight in the range of 1,000 to 3,000 was added in a ratio of 12 to 16% by weight, and a chain extension reaction was performed to prepare a primary polyurethane resin. The third step; Agent for preparing a secondary polyurethane resin having a solid content of 75 to 87% by weight by reacting the prepared primary polyurethane resin with a low molecular weight amine chain extender (k) in a ratio of 0.1 to 0.4% by weight It is characterized in that it consists of four steps. And the moisture-permeable and waterproof fabric of the present invention is a melamine curing agent (l) 4 to 8 parts by weight, NCO curing agent (m) 1 to 2 parts by weight, curing accelerator based on 100 parts by weight of the high solid hydrophilic water-dispersible polyurethane resin obtained by the above manufacturing method. (n) A mixture of 0.5 to 2 parts by weight and 0 to 3 parts by weight of an antifoaming agent (o) is applied on the fabric in an amount of 30 to 50 g/m 2 to form a base coating layer, and the coated fabric Silver is characterized by having a water pressure of 10,000 to 20,000 mmH 2 O, a water pressure of 8,000 to 15,000 mmH 2 O after washing 10 times, and a moisture permeability of 8,000 to 11,000 g/㎡·day. The high solids hydrophilic water-dispersible polyurethane resin for textile coating obtained by the manufacturing method of the present invention uses the existing hydrophilic water-dispersible polyurethane resin for base coating, after the phenomenon of coating weight reduction and thickening as seen during direct coating on fabric. It is possible to form a more stable coating by improving the creamy flow that appears, and it is possible to realize coating characteristics such as excellent water pressure, washing durability, and moisture permeability while realizing a sufficient film thickness even with a single coating. In addition, the moisture-permeable waterproof fabric coated using the hydrophilic water-dispersible polyurethane resin of the present invention shows a moisture permeability of 8,000g/m²·day or more, a water pressure of 10,000 mmH 2 O or more, and excellent laundry durability, and has no stickiness on the surface and is soft. It has the effect of having a touch. |
