Title:
PRECURSOR FOR SUPER-HYDROPHOBIC COMPOSITE COATING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/073315
Kind Code:
A1
Abstract:
Disclosed in the present invention are a precursor for a super-hydrophobic composite coating and a preparation method therefor. The preparation method comprises the following steps: coating an ACNTB-SiO2 coupling agent suspension, in parts by weight, on the surface of a gel body of a mixture of the ACNTB-SiO2 coupling agent, an epoxy resin, a diglycidyl-ether-terminated polydimethylsiloxane, and an amino-terminal hyperbranched polysiloxane, and volatilizing a solvent, so as to obtain the precursor for the super-hydrophobic composite coating; and then performing curing, so as to obtain the durable super-hydrophobic composite coating. The durable super-hydrophobic composite coating has the characteristics of simple operations, durability and good hydrophobicity; and the prepared coating has excellent mechanical properties and wear resistance. In particular, hydrophobic nano-SiO2 particles of the present invention are stored in pores of ACNTB; when the coating structure is destroyed, an adhesive is decomposed in a pyrolysis manner, the formed gas product can promote the migration of SiO2 to the surface of the coating, and a new nano-structure surface is constructed by SiO2 and exposed CNT, recovering the super-hydrophobic performance of the coating.
