The invention discloses a solar air conditioner. The solar air conditioner comprises a
metal shell, wherein the surface treatment is performed for the
metal shell, and comprises the following steps: 1) 1-2 parts of 2-hydroxyphosphonoacetic acid by
mass, 1.4 parts of methyl ethyl
ketone by
mass, 1.1 parts of hexadecanol
polyoxyethylene ether-9 by
mass, 0.8 part of chlorinated
coconut oil based trimethyl
ammonium by mass, 1.3 parts of 6, 6, 10-trimethyl bicyclo-3, 1, 1-hepta-2-
alkene by mass, 2.7 parts of
isopropyl palmitate by mass and 1.4 parts of hydroxyl propyl
methyl cellulose by mass are added in 15 parts of de-ionized water by mass for uniformly mixing to prepare surface treatment
working fluid; 2) the surface treatment
working fluid is heated up to a temperature of 65 DEG C; and 3) the
metal shell is put in the surface treatment
working fluid for dipping by 24 minutes, and is taken out for
drying. The surface treatment is performed for the metal shell of the solar air conditioner, so that the metal shell has the performances of excellent
water resistance,
corrosion resistance,
rust resistance, electrostatic resistance,
heat resistance,
cold resistance and
weather resistance.
