The invention discloses a preparation method for antistatic super hydrophobic
composite coating, comprising the following steps: dissolving 0.2-2 parts of
styrene-
maleic anhydride alternate
copolymer by weight into 20-1000 parts of
solvent by weight, adding 1 part of
carbon nanotube by weight and then evenly mixing, adding 0-26 parts of
ammonia water and 0.2-2 parts of
silicate ester or
titanate compound by weight, stirring and mixing to enable
silicate ester or
titanate compound to perform
hydrolysis reaction, adding 0.1-2 parts of
silicate ester or
titanate compound and 0.02-0.5 part of
fluorine containing
silane coupling agent by weight, evenly mixing and spraying on base materials, carrying out aging and
thermal treatment to obtain stable antistatic super hydrophobic
composite coating. The invention has simple operation and mild condition, the
carbon nanotube can be directly used without the need of any
chemical modification, the obtained
composite coating has good hydrophobicity,the static
contact angle and
rolling angle between the composite
coating and water are respectively larger than 150 degrees and less than 3 degrees, and the
surface resistivity is 106-1011
omega, thus meeting the requirement of antistatic transparent
coating and having wide application prospect.
