Investigation of conditions for creation of hydrophobic coatings
Keywords:
hydrophobic coating, silicone waste, hydrophobic powderAbstract
As part of the planned work, work was carried out to create hydrophobic fillers and waterproofing construction materials based on the obtained carbon nanomaterials with superhydrophobic properties, such as water-repellent and self-cleaning surfaces, and anticorrosion paints. To achieve this goal, a hydrophobic silica powder, obtained by burning silicon waste, and a hydrophobic carbon black, which is formed during combustion of the propane-butane gas mixture, was applied to the surface of the metal and drywall, and the surface properties of the materials were investigated. Work was done on imparting waterproofing properties to putty using superhydrophobic carbon black as a filler. Studies have shown that the addition of soot increases the hydrophobic properties of the putty to a certain limit, the maximum wetting angle (above 150 °) was recorded at a concentration of soot equal to 8%.
