Abstract

The invention discloses a waterborne polyurethane waterproof moisture-permeable coated fabric and a preparation method thereof. The waterborne polyurethane coating is prepared from the following raw materials in parts by weight: 140-150 parts of polyester polyol, 20-24 parts of toluene diisocynate, 40-50 parts of diphenyl-methane-diisocyanate, 8-12 parts of 2,2-dimethylolpropionic acid, 7-9 parts of neopentyl glycol, 3-5 parts of trimethylolpropane, 6-10 parts of dibutyltin dilaurate, 4-6 parts of a DH-1 reinforcing agent, 2-3 parts of an antioxidant TNP, 9-11 parts of an ultraviolet absorbent, 8-12 parts of a dyeing agent, 6-7 parts of liquid paraffin, 4-5 parts of antimony trioxide, 5-7 parts of polytetrahydrofuran dibasic alcohol, 6-8 parts of nanosilicon dioxide, 0.8-1.2 parts of dicumyl peroxide, 7-9 parts of 2,6-Di-tert-butyl-4-methylphenol (BHT), 15-19 parts of deionized water and 7-9 parts of auxiliary. The coated fabric which is high in elongation at break and high in moisture and air permeability is prepared, and the properties such as the elongation at break, the moisture and air permeability, the aging resistance, the flame retardance and the electrostatic resistance of modified polyurethane can be effectively improved.

Description

technical field [0001] The invention relates to a preparation method of a coated fabric, in particular to a water-based polyurethane waterproof and moisture-permeable coated fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for knitted fabrics, which not only require fabrics to be comfortable to wear, but also require fabrics to have functions such as waterproof, moisture-permeable, deodorizing and antibacterial. Waterproof and moisture-permeable fabric means that water does not soak into the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside world through the fabric in the form of water vapor, so as to avoid sweat accumulation and condensation between the body surface and the fabric to keep the clothing comfortable It is a high-tech, unique functional fabric. People use technologies such as lamination, c...
