Description

Technical Field

[0001] The present invention relates to a deicing agent based on a solar thermal conversion mechanism and a manufacturing method thereof, which can be widely used in the field of melting ice and snow in road traffic. Background Art

[0002] Snow melting agent refers to a drug that helps to melt ice and snow. Snow melting agent melts the snow on the road by lowering the melting temperature of ice and snow, thus removing snow and de-icing urban roads, highways, airports, ports, and bridge facilities, and clearing roads.

[0003] Currently, there are two main types of snow-melting agents in China. One is an organic snow-melting agent with acetate as the main component, which has basically no corrosive effect on infrastructure, but its price is too high and it is only used in small quantities in important places such as airports.

[0004] Inorganic de-icing agents based primarily on chloride salts, commonly known as de-icing salts, are widely used in cities and on highways. These agents, such as sodium chloride, calcium chloride, magnesium chloride, and potassium chloride, are inexpensive, but they can cause severe corrosion to large public infrastructure. Studies have shown that chloride salt residues can corrode road surfaces and rubber tires, damage concrete structures and bridges, and harm trees, crops, animals, and humans. Summary of the Invention

[0005] The purpose of the present invention is to provide a snow-melting agent based on the solar thermal conversion mechanism and a method for manufacturing the same, which can accelerate the melting of ice and snow, fix carbon black, reduce carbon black loss, extend the snow melting time, extend the service life of the road surface, be environmentally friendly, low-cost, realize the utilization of waste resources, reduce dependence on natural resources, and have significant social, economic and environmental benefits.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a snow-melting agent based on the solar thermal conversion mechanism, which includes natural multi-porous basalt tailings sand, waste petroleum coke powder carbon black, coal slag powder carbon black, and petroleum resin. The mass proportions of each component are: 30 to 68 parts of natural multi-porous basalt tailings sand, 20 to 60 parts of waste petroleum coke powder carbon black, 20 to 60 parts of coal slag powder carbon black, and 6 to 12 parts of petroleum resin.

[0007] The present invention provides a method for manufacturing the de-icing agent based on the solar thermal conversion mechanism, comprising mixing and stirring the components of the de-icing agent according to their mass fractions for 1-8 hours, and drying the mixture at a temperature of 20-80° C. to obtain a finished de-icing agent.

[0008] The present invention discloses a deicing agent based on a solar-thermal conversion mechanism. Compared to existing technologies, these deicing agents primarily accelerate snow and ice melting by lowering the freezing point of water. The existing deicing mechanism is based on the principle of freezing point depression, which is fundamentally based on the principle of snow melting. However, the present invention's deicing principle breaks through conventional technology. Previous deicing agent research has not utilized the blackness coefficient of deicing agent materials to improve their ability to melt snow and ice. The present invention, based on the solar-thermal conversion mechanism, converts solar energy into thermal energy. By utilizing the blackness coefficient and microstructure of the deicing agent material, it maximizes the ability of snow and ice to absorb solar radiation, converting solar energy into thermal energy and melting the snow and ice.

[0009] The present invention discloses a de-icing agent based on the solar thermal conversion mechanism. The detailed de-icing process is as follows: Based on the solar thermal conversion mechanism, the blackness coefficient and microstructure of the de-icing agent material are utilized to maximize the absorption capacity of ice and snow for solar radiation, reduce reflection and scattering, convert solar energy into heat energy, and melt the ice and snow. The blackness coefficient refers to the ability of an object to absorb radiation. If 100% of the radiation is absorbed, the blackness coefficient is 1, and if no radiation is absorbed, it is 0. At the same time, the thermal radiation from the sun or other objects is a radiation heat exchange. Its principle is the radiation heat exchange between two objects with different temperatures and no contact with each other. The heat exchange process carried out through electromagnetic waves is one of the important ways of heat transfer. Every object in nature is constantly emitting radiant heat into space, while at the same time constantly absorbing radiant heat emitted by other objects. The radiation heat exchange between solid surfaces depends on the radiation angle coefficient F and the blackness ε value. The blackness ε value of white ice and snow is close to 0, and the reflectivity of solar radiation is as high as 90%. White ice and snow can only absorb about 10% of the solar radiation energy. Dark or black materials, such as dark or black, have a blackness ε close to 1 and a reflectivity of 10-0%. Compared with white ice and snow, the radiation heat transfer energy absorption of the two differs by about 9 times.

[0010] This invention discloses a deicing agent based on a solar-thermal conversion mechanism and its manufacturing method. The deicing agent material, laid on roads, absorbs sunlight and converts it into heat, thereby raising the road surface temperature and accelerating the melting of ice and snow. This ensures its effectiveness and durability in various climate conditions.

[0011] The present invention describes a deicing agent based on a solar-thermal conversion mechanism and its manufacturing method. This innovative solution combines solar-thermal conversion technology with a deicing agent. By adding materials that enhance the photothermal conversion effect, the deicing agent efficiently absorbs sunlight and converts it into heat, improving snowmelt efficiency. This combination exhibits unique advantages in specific environments, particularly in regions with abundant solar resources and cold winters. Therefore, the present invention combines solar-thermal conversion technology with a deicing agent for innovative applications in the snowmelt process.

[0012] The invention discloses a snow-melting agent based on a solar heat conversion mechanism and a manufacturing method thereof. The agent is suitable for working at a temperature of -1°C to -40°C, can be spread before snowfall and maintained for 30 to 60 days, and has a fast snow-melting speed.

[0013] The present invention discloses a deicing agent based on a solar-thermal conversion mechanism. The waste coke and coal slag carbon black serve as solar radiation absorbers, converting the absorbed sunlight into heat, thereby increasing the temperature of the natural porous basalt tailings sand in the deicing agent's matrix. This deicing agent has a wide operating temperature range and a long snow-melting effect, thereby accelerating the melting of ice and snow.

[0014] The present invention discloses a deicing agent based on solar thermal conversion. The deicing agent contains a small amount of petroleum resin, which is resistant to water, ethanol, and chemicals, chemically stable to acids and alkalis, and capable of adjusting viscosity and exhibiting good thermal stability. The petroleum resin acts as a tackifier, accelerator, regulator, and modifier, along with other ingredients, contributing to the deicing agent's viscosity and thermal stability.

[0015] The present invention discloses a deicing agent based on a solar thermal conversion mechanism. Natural multi-porous basalt tailings sand serves as the deicing agent matrix, synergistically acting with the aforementioned waste petroleum coke carbon black, coal slag carbon black, and petroleum resin components. The multi-porous adsorption capacity of the natural multi-porous basalt tailings sand absorbs the waste petroleum coke carbon black and coal slag carbon black components into the cavities of the multi-porous basalt tailings sand. The viscosity and thermal stability of the petroleum resin are simultaneously utilized to bond the various components together, providing a maintenance effect on the road surface and extending its service life. Therefore, the natural multi-porous basalt tailings sand has the ability to adsorb waste petroleum coke carbon black and coal slag carbon black, thereby fixing the carbon black, reducing carbon black loss, and extending the deicing time.

[0016] The present invention utilizes a solar thermal conversion mechanism to produce a deicing agent. Because the resulting deicing agent is chlorine-free, it is non-corrosive and harmless to roads, public facilities, metals, cement, soil, greenery, and the water ecosystem. This addresses the corrosion and environmental bottlenecks of traditional deicing methods at the source, which is of great significance. Therefore, it is environmentally friendly.

[0017] The present invention discloses a snow-melting agent based on the solar thermal conversion mechanism. The present invention utilizes natural multi-porous basalt tailings sand waste, comprehensively utilizes it, and turns waste into treasure at low cost. It can not only solve the environmental pollution and safety hazards caused by the stacking of tailings sand, but also convert it into a usable resource. Therefore, it realizes the utilization of waste resources, reduces dependence on natural resources, and has significant social, economic and environmental benefits.

[0018] The present invention discloses a de-icing agent based on a solar thermal conversion mechanism. Compared with existing chloride-based de-icing agent technology, field experiments have demonstrated that the present invention outperforms chloride-based de-icing agents. First, chloride-based de-icing agents are corrosive to metals, while the present invention's de-icing agent is non-corrosive. Second, chloride-based de-icing agents are corrosive to cement, while the present invention's de-icing agent is non-corrosive. Third, with the exception of potassium chloride, chloride-based de-icing agents have an impact on soil, while the present invention's de-icing agent has no such impact. Fourth, chloride-based de-icing agents use the freezing point principle to melt snow, while the present invention uses a solar thermal conversion mechanism to melt snow, resulting in fundamentally different snow-melting principles. Fifth, the present invention's de-icing agent melts snow faster than chloride-based de-icing agents. Sixth, the present invention's de-icing agent has a wider suitable operating temperature range than chloride-based de-icing agents. Seventh, the present invention's de-icing agent can be sprayed and maintained for longer periods of time before snowfall than chloride-based de-icing agents.

[0019] In summary, the snow-melting agent of the present invention, which is based on the solar thermal conversion mechanism, accelerates the melting of ice and snow, fixes carbon black, reduces carbon black loss, prolongs the snow-melting time, prolongs the service life of the road surface, is environmentally friendly, low-cost, realizes the utilization of waste resources, reduces dependence on natural resources, and has significant social, economic and environmental benefits.
