Embodiment 1

[0014] A kind of PU silver surface coating process of camouflage tent cloth, during coating, carry out PU silver surface coating to base cloth with polyurethane silver paste, described polyurethane silver paste comprises one-component polyurethane, aluminum silver paste, methyl ethyl ketone, Dimethylformamide, and the weight ratio of the one-component polyurethane, aluminum silver paste, methyl ethyl ketone, and dimethylformamide is 50:10:25~30:5~10. The weight ratio of the one-component polyurethane, aluminum silver paste, methyl ethyl ketone, and dimethylformamide is 50:10:28:8. The preparation process of the polyurethane silver paste is as follows: first add a part of the solvent to the aluminum silver paste, stir well, then add the polyurethane glue, add the remaining solvent while stirring, adjust the viscosity to 5000~6000mPa·S, and let it stand for 30min or Vacuum for defoaming. The process parameters for PU silver surface coating are as follows: use a sharp angle scra...

Embodiment 2

[0016] The difference from Example 1 is that the weight ratio of the one-component polyurethane, aluminum silver paste, methyl ethyl ketone, and dimethylformamide is 50:10:25:5. The preparation process of the polyurethane silver paste is as follows: first add 2 / 5 of the solvent to the aluminum silver paste, stir well and then add polyurethane glue, add the remaining solvent while stirring, adjust the viscosity to 5000mPa·S, and let it stand for 30min . The process parameters for PU silver surface coating are as follows: use a sharp angle scraper, the scraper angle is 110 degrees, the magnetic force of the magnetic roller is 75%, the oven temperature in the front area is 125°C, the oven temperature in the rear area is 145°C, and the drying time is 30s .

Embodiment 3

[0018] The difference from Example 1 is that the weight ratio of the one-component polyurethane, aluminum silver paste, methyl ethyl ketone, and dimethylformamide is 50:10:30:10. The preparation process of the polyurethane silver paste is as follows: firstly add half of the solvent to the aluminum silver paste, stir well, then add polyurethane glue, add the remaining solvent while stirring, adjust the viscosity to 6000mPa·S, and vacuumize for defoaming. The process parameters for PU silver surface coating are as follows: use a sharp angle scraper, the scraper angle is 125 degrees, the magnetic force of the magnetic roller is 85%, the oven temperature in the front area is 135°C, the oven temperature in the rear area is 155°C, and the drying time is 40s .

[0019] The polyester oxford cloth prepared by the present invention has good high hydrostatic pressure resistance, firm texture, wear resistance, and good air and moisture permeability, and can be used as marching tents, rain...

Abstract

The present invention provides a PU silver surface coating process of camouflage tent cloth. According to the process, during coating, a polyurethane silver paste is adopted to carry out PU silver surface coating on a fabric, wherein the polyurethane silver paste comprises single-component polyurethane, an aluminum silver paste, methyl ethyl ketone and dimethylformamide, and a weight ratio of the single-component polyurethane to the aluminum silver paste to the methyl ethyl ketone to the dimethylformamide is 50:10:25-30:5-10. According to the present invention, the process is reasonable, economic cost is low, and the fabric can have characteristics of high color fastness to light, high hydrostatic pressure resistance, good gas permeation, and good moisture permeation.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a PU silver surface coating process for a camouflage tent fabric. Background technique [0002] Textile coating finishing agent, also known as coating glue, is a polymer compound that is evenly coated on the surface of the fabric. Through bonding, it forms one or more layers of film on the surface of the fabric, which improves the appearance and style of the fabric, adds additional functions, and has special functions such as waterproof, moisture permeability, flame retardancy, and hydrostatic pressure. As early as more than 2,000 years ago, the ancient Chinese people had applied natural compounds such as lacquer and tung oil to the surface of fabrics to make waterproof cloths. In modern times, a variety of polymer coating adhesives with superior performance have appeared. The textiles coated by the existing coating technology are only waterproof but not moisture-permeable.
