Embodiment Construction

[0041] See figure 1 — Figure 6 , the present invention will be described in detail below through specific examples.

[0042] Step 1: The substrate is sanded or sandblasted, and cleaned repeatedly to obtain a clean and rough surface and improve the bonding force between the coating and the substrate.

[0043] Step 2: Spray a heat-insulating coating on the surface of the treated substrate to prevent heat from being transmitted to the inside of the material and improve thermal efficiency.

[0044]Step 3: After the heat insulation material is completely cured, cover the part that does not need to be sprayed to form a linear arrangement with controllable resistance. Hydrophilic treatment of the surface of the material. Dilute the high-temperature-resistant conductive adhesive with deionized water, stir for 10 minutes, and spray it on the surface of the treated substrate under high pressure. Curing at room temperature for 24 hours, remove the cover after complete curing, fix th...

Abstract

The invention discloses a preparation method for an energy-saving anti-icing / deicing coating combining a super-hydrophobic coating and a heating coating. The preparation method includes seven steps. The novel heating coating is added based on the super-hydrophobic coating, the super-hydrophobic coating anti-icing technology and the heating anti-icing technology are combined, and a novel anti-icing technology is provided. The super-hydrophobic coating is obtained by modifying commercial gas-phase silicon dioxide with fluoroalkyl silane, mixing the modified commercial gas-phase silicon dioxide with resin according to a proper proportion and meanwhile adding heat-conductive particles. The heating coating is obtained by evenly spraying high-temperature-resistant conductive resin into a fixed shape and then attaching aluminum foil to two ends as electrodes. The preparation method for the energy-saving anti-icing / deicing coating combining the super-hydrophobic coating and the heating coating has the advantages of coating anti-icing and electric heating anti-icing, improves the heat efficiency by changing the heating mode, and realizes efficient and energy-saving deicing.

Description

technical field [0001] The invention belongs to the technical field of functional coatings in chemistry and chemical engineering, and relates to a method for preparing an energy-saving anti-icing coating combined with a super-hydrophobic coating and a heating coating, which is an energy-saving composite anti-icing coating preparation method. A new heating anti-icing method is adopted, which is combined with coating anti-icing technology. By spraying heating coating and super-hydrophobic coating on the substrate, the anti-icing effect of low heat and energy saving is realized. Background technique [0002] Relying on its unique surface properties, superhydrophobic coatings have great application value in the fields of self-cleaning, anti-fouling, anti-ice and snow, etc., and have become one of the most active research topics and hot issues. The anti-icing principle of the superhydrophobic coating is based on the hydrophobicity and microstructure of the superhydrophobic surfac...
