Embodiment 1
[0042] (1) Use low-emissivity base material: polyester aluminized cloth (aluminized on one side, low-emissivity base material on one side, and the emissivity of the low-emissivity side is 0.1).
[0043] (2) Preparation of white camouflage paint for low-emissivity surface of snow camouflage net: use 30 parts of elastic polyurethane (TPU-5377A), dissolve in 180 parts of DMF, dissolve at 60°C, and stir at 500rmp / min. After completely dissolving, Add 0.9 parts of dispersant (904S), 1.2 parts of adhesion promoter (KH-550), stir for 30 minutes in a high-hardness stainless steel dispersion device with a stirring rate of 800rmp / min, and slowly add 45 parts of silicon dioxide (30 parts of nano-dioxide Silicon + 15 parts of hydrophobically modified nano-silica) and 90 parts of diluent butanone, after the addition, continue to stir for 30 minutes with a stirring rate of 500rmp / min, after stirring and dispersing evenly, the dispersed materials are used for horizontal sand milling Machine ...
