Embodiment 1
[0059] A heat-insulating coating for outdoor textiles, the parts by weight of each component are:
[0060] Silicon dioxide 6 parts
[0061] Aluminum oxide 2 parts
[0062] Zinc oxide 10 parts
[0063] Rutile titanium dioxide 4 parts
[0064] PU glue 100 parts
[0065] 1 part dispersant
[0066] Bridging agent 2.5 parts
[0067] Leveling agent 1 part
[0068] 0.5 parts of defoamer
[0069] Toluene 0 parts
[0070]Acetone 45 parts
[0071] Anti-sticking agent 1 part.
[0072] Wherein, the dispersant is a common dispersant for solvent-based textile coating finishing.
[0073] The preparation steps are:
[0074] (1) Weigh by weight;
[0075] (2) Mix silicon dioxide, zinc oxide, aluminum oxide and rutile titanium dioxide with an appropriate amount of solvent to obtain the first component. The solvent is toluene or acetone, and the amount is such that the viscosity of the coating adhesive can be smooth. Production, adjust the viscosity is generally 5000 ~ 12000;
