Description
Technical Field
The invention relates to the field of power grid ice coating prevention, in particular to an ice coating prevention coating suitable for power grid equipment.
Background
The ice coating of the transmission line seriously threatens the safe operation of the global power network. In canada, russia, the united states, norway, sweden, czech, japan, uk, finland, iceland and severe cold zones in the north and middle-western parts of our country, ice coating on the transmission lines causes circuit damage and safety accidents caused by the damage, which seriously affects people's production and life and causes huge economic loss. With the development of global electric power industry, the ultra-long distance power transmission needs to penetrate high-altitude areas with high coldness, high humidity and high altitude, the problem of line icing disasters is more serious, and the problem of power grid icing prevention is more prominent.
The main freezing disaster prevention and control methods and the problems thereof are as follows: canada and other countries adopt a method for strengthening line design to prevent ice, but the method has large financial investment and poor economy, and the fact proves that only slight ice coating can be prevented, and large-area tower collapse accidents can still occur under the severe ice freezing disaster; china mainly adopts a direct-current ice melting method to prevent ice, the anti-ice effect is good, the anti-ice speed is high, and power failure operation is required. The power grid ice-coating prevention technology comprises traditional passive ice removal modes such as mechanical ice removal and thermal ice removal, and a novel active ice removal mode for coating material ice removal. The coating material prevents the formation of ice coating, melts the ice or reduces the adhesion of the ice to the ice coating surface by using the physical structure or chemical composition of a special material, thereby removing the ice. According to the anti-icing principle, the anti-icing of the coating material is an ideal anti-icing mode, the investment of manpower, material resources and financial resources is greatly reduced, and the coating material is environment-friendly. However, because the anti-icing performance is not ideal, an anti-icing coating material which can be popularized and applied does not exist so far.
Disclosure of Invention
In order to solve the problems in the prior art, the invention aims to provide an anti-icing coating suitable for power grid equipment, and a preparation method and application thereof.
In order to realize the purpose of the invention, the technical scheme of the invention is as follows:
in a first aspect, the invention provides an anti-icing coating suitable for power grid equipment, which is characterized by comprising the following raw materials in parts by mass: 6-12 parts of pigment, 0.5-2 parts of filler, 15-32 parts of resin, 47.5-70 parts of solvent, 2-6 parts of dispersing agent, 0.1-1 part of defoaming agent and 1-2 parts of flatting agent;
wherein the pigment consists of zirconium oxide, ruthenium oxide and cobaltosic oxide according to the mass ratio of 1:1: 1.
The cobaltosic oxide has lower sunlight absorptivity in an ultraviolet visible near-infrared region due to higher reflectivity, and the addition of the zirconium oxide and the ruthenium oxide can effectively reduce the reflectivity of the cobaltosic oxide, thereby leading to high sunlight absorptivity. The high solar absorption rate will concentrate more heat energy in the coating, thereby accelerating the melting of the ice coating on the substrate surface. The three powders of zirconium oxide, ruthenium oxide and cobaltosic oxide according to the mass ratio of 1:1:1 can effectively ensure that the coating has high sunlight absorption rate and achieves the optimal energy gathering effect.
Further, the zirconia, the ruthenium oxide and the cobaltosic oxide are nano powder, the particle size is 20-120 nm, and the specific surface area is 20-80 m2/g。
Still further, the filler is nano silica; the resin is polyurethane modified organic silicon resin; the solvent is one of dimethylbenzene, ethyl acetate, n-butyl acetate, methyl butanone and cyclohexanone; the dispersant is one of TEGO Dispers 760W, TEGO Dispers655 and TEGO Dispers 735; the defoaming agent is one of TEGO Airex932 and TEGO Airex 902W; the leveling agent is one of TEGO 410 and TEGO 450.
In a second aspect, the invention provides a preparation method of the anti-icing coating, which specifically comprises the following steps: adding the solvent, the dispersing agent, the defoaming agent, the flatting agent and the resin into a container, mixing, stirring and dispersing; then adding the pigment and the filler, and stirring and dispersing at the rotating speed of 900-1000 r/min for 50-70 min; and then, carrying out dispersion grinding by using a sand mill or a ball mill, and carrying out dispersion grinding on the fineness until the fineness reaches 10-20 mu m to obtain the anti-icing coating.
In specific implementation, after dispersion and grinding, filtering is carried out by using a 200-mesh wire mesh, and the filtered coating is filled into a container and sealed.
In a third aspect, the invention provides an application of the anti-icing coating in anti-icing of power grid equipment.
The materials of the power grid equipment include, but are not limited to, aluminum conductor steel reinforced and Q235 angle steel.
The specific operation of the application is as follows: and coating the anti-icing coating on the surface of the power grid equipment with anti-icing requirements, and curing at room temperature to obtain the anti-icing coating.
Preferably, the coating thickness of the anti-icing coating is 20-80 μm.
The raw materials or reagents involved in the invention are all common commercial products, and the operations involved are all routine operations in the field unless otherwise specified.
The above-described preferred conditions may be combined with each other to obtain a specific embodiment, in accordance with common knowledge in the art.
Compared with the prior art, the invention at least has the following advantages and beneficial effects:
the invention adopts the nanometer composite powder of zirconium oxide, ruthenium oxide and cobaltosic oxide as the pigment, and utilizes the optical synergistic enhancement effect to powerfully ensure the energy-gathering effect of the coating under the ice-coating working condition, thereby achieving the effects of preventing ice coagulation and removing ice.

Experimental example 1
Subject: the coatings prepared in examples 1 to 3 and comparative examples 1 to 2.

1. the coatings prepared in examples 1 to 3 and comparative examples 1 to 2 were respectively sprayed onto an aluminum-steel-cored twisted wire using a spray gun, and the coating thickness was 50 μm.
2. And (3) placing the steel-cored aluminum strand coated with the coating and the steel-cored aluminum strand not coated with any coating (contrast) in a refrigerator, then spraying water mist, standing for 2 hours at minus 10 ℃, and finally forming thin ice on the surface of the steel-cored aluminum strand.
3. And turning on the direct current stabilized power supply, and supplying power to a halogen lamp placed in the refrigerator by regulating voltage and current.
