Description

technical field [0001] The invention belongs to the field of multifunctional coating materials, and in particular relates to a fireproof and hydrophobic material and a preparation method thereof. Background technique [0002] High-strength and durable super-hydrophobic coating has the characteristics of waterproof, anti-corrosion, anti-icing, dust-proof, self-cleaning, etc. It is widely used on the surface of electronic devices, oil-water separation, food packaging, decoration and other fields. Most of the fields of application mentioned above place high demands on fire performance. Therefore, superhydrophobic coatings should be designed with a fireproof function to meet practical needs. [0003] At present, the common method of constructing fire-resistant superhydrophobic coatings is to introduce fire-resistant and flame-retardant nanoparticles into the hydrophobic structure as a skeleton substance, and improve the fireproof performance of the superhydrophobic surface by v...
