[0045] The preparation method of high weather resistance anti-sticking coating comprises the following steps:
[0046] Step 1, prepare the main agent: mix the resin, solvent 1 and solvent 2 added for the first time, stir evenly, then add defoamer and nano additives, disperse for 5 minutes, then slowly add anti-sedimentation agent and silicone oil, After dispersing for 3 minutes, add pigment 1, filler and pigment 2 in order, disperse at 850r / min for 10min, then increase the speed and disperse at 3000r / min for 20min, then reduce the speed to 1600r / min, then add the remaining Solvent 1 and the remaining solvent 2 can be continuously dispersed for 3 minutes; the mass parts of each component in Step 1 of Examples 1-3 are shown in Table 1.
