Abstract
The invention relates to a preparation method of a silicone rubber-based superhydrophobic coating with a noctilucent function. The preparation method comprises the following steps: dissolving 25 g of silicone rubber, 1 g of a curing agent and 0.25 g of an accelerant in 100 ml of hexane so as to obtain a clear solution; pouring the solution on a glass panel, performing natural streaming and performing filming; at the same time, mixing noctilucent powder with polytetrafluoroethylene powder which are the same in mass in an agate mortar for 1 h until the color is uniform, so that mixed powder is obtained; uniformly spreading 10-30 g of the mixed powder to a silicone rubber membrane surface by using a 80-mesh stainless steel sampling sieve, and performing standing and solidification for 24 h; finally, cleaning the surplus powder on a surface layer with a great deal of dehydrated alcohol so as to obtain the superhydrophobic coating with the noctilucent function. The silicone rubber-based superhydrophobic coating with the noctilucent function, disclosed by the invention, not only has the functions of self-cleaning and preventing pollution, but also can achieve the effects of attracting attention, decoration and the like at night, has the efficacy of energy conservation, and does not need electric energy.
