Description

Technology Field

[0001] The present invention relates to a de-icing agent and a method for manufacturing the same, and more specifically, to a liquid de-icing agent composed of sodium chloride (NaCl), water, and a freezing liquid and a method for manufacturing the same, which can prevent black ice from forming on roads. Background Technology

[0003] First, if we look at the prior art,

[0004] Generally, anti-slip paving materials are applied to roads in areas such as steep slopes, curves with small radii, intersections of sloped sections, areas with poor visibility, and in front of crosswalks with high pedestrian traffic, for the purpose of increasing slip resistance and shortening vehicle braking distances.

[0005] Compositions for anti-slip paving materials used to form such anti-slip paving materials are being developed and constructed using various materials and methods. However, due to the characteristics of roads, there is a problem of having to block vehicle traffic during construction and drying, so materials and methods are required that facilitate construction and dry quickly to rapidly connect traffic.

[0007] Meanwhile, when snow falls during the winter season, it is prone to freezing, and since such freezing can lead to vehicle accidents and pedestrian safety accidents, it is necessary to prevent the roads from freezing by promptly melting the snow accumulated on the roads. In particular, as record-breaking heavy snowfall has been occurring frequently recently due to abnormal weather phenomena, a great deal of attention is being paid to preventing road freezing during the winter.

[0009] In addition, snow accumulates or freezes in anti-slip sections constructed with conventional anti-slip paving materials or anti-slip agents using acrylic copolymer resin as a binder, causing vehicle slip accidents and becoming a major cause of traffic accidents during the winter season.

[0011] As such, currently, methods such as spreading sand or calcium chloride on roads are used to prevent snow accumulation or freezing; however, in the event of sudden heavy snowfall, calcium chloride or sand must be spread directly onto the roads, making rapid snow melting impossible and requiring a significant amount of time, personnel, and equipment.

[0012] In addition, since calcium chloride has the problem of lowering its concentration and eventually freezing again if it continues to snow after application, this method cannot fundamentally solve slipping accidents on snowy or icy roads.

[0014] According to recent research, various mixtures are being proposed as eco-friendly and more effective alternatives to traditional de-icing agents such as calcium chloride.

[0015] For example, there are research results showing that a de-icing agent mixed with calcium chloride and organic materials is more effective in preventing freezing.

[0016] This suggests the possibility of partially resolving the problems associated with existing de-icing agents.

[0018] Accordingly, the following have been disclosed in the past: 'eco-friendly de-icing agent and method of manufacturing the same' under Patent No. 10-2536897, 'eco-friendly solid de-icing agent and method of manufacturing the same' under Patent No. 10-1764694, 'eco-friendly de-icing agent with enhanced anti-refreezing function and method of manufacturing the same' under Patent No. 10-2371764, and 'composition of a surface treatment agent for preventing freezing of road pavement and a method of surface treatment for preventing freezing of road pavement using the same' under Patent No. 10-2142987; however, the aforementioned problems are still not being improved. The problem to be solved

[0020] Accordingly, the present invention was devised to solve the problems of the aforementioned prior art, and has been completed as a technical objective with a focus on providing a liquid de-icing agent composed of sodium chloride, water, and a freezing liquid, and a method for manufacturing the same, which can prevent the formation of black ice on road surfaces in advance, use a freezing liquid composed of environmentally harmless components, prevent high freezing even at low temperatures, and ensure non-freezing. means of solving the problem

[0022] Accordingly, the present invention is characterized by a de-icing agent for preventing road freezing, wherein the de-icing agent comprises sodium chloride (NaCl), water, and a freezing liquid, and has a black ice prevention function as its technical feature.

[0024] In addition, regarding a de-icing agent for preventing freezing of roads, the technical feature is a liquid de-icing agent having a black ice prevention function, characterized in that the de-icing agent comprises 100 parts by weight of water, 10 to 40 parts by weight of silica sol, 0.1 to 2 parts by weight of sodium oxide, 0.5 to 2 parts by weight of sodium silicate, 0.5 to 2 parts by weight of 3-aminopropyltrimethoxysilane, and 0.1 to 0.5 parts by weight of aerogel.

[0026] In addition, the technical features of the method for manufacturing a de-icing agent that prevents road freezing include: using the above-mentioned liquid de-icing agent; a preparation step of preparing raw materials (sodium chloride, water, freezing liquid) used in the de-icing agent; a mixing liquid preparation step of mixing the sodium chloride and water, adding 10 to 35 parts by weight of sodium chloride relative to 100 parts by weight of water to prepare a mixture; and a de-icing agent manufacturing step of mixing the freezing liquid with the mixture, adding 5 to 30 parts by weight of the freezing liquid relative to 100 parts by weight of the mixture to produce the de-icing agent. Effects of the invention

Furthermore, since the main component is water, it can minimize metal corrosion on the road surface, increase the durability of road facilities, and prevent ice formation, among other effects. Brief explanation of the drawing

[0030] FIG. 1 is a flowchart of the method for manufacturing a liquid de-icing agent according to the present invention. Specific details for implementing the invention

[0031] Hereinafter, with reference to FIG. 1, a preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described as follows.

[0033] First of all, the liquid de-icing agent having a black ice prevention function according to the present invention is,

[0034] In a de-icing agent for preventing road freezing, the de-icing agent comprises sodium chloride (NaCl), water, and a freezing liquid.

[0036] Another embodiment of the present invention is,

[0039] In addition, the method for manufacturing a liquid de-icing agent according to the present invention is,

[0040] A method for manufacturing a de-icing agent to prevent freezing of roads comprises: a preparation step of preparing raw materials (sodium chloride, water, freezing liquid) used in the de-icing agent, wherein the above-mentioned liquid de-icing agent is used; a mixing liquid manufacturing step of mixing the sodium chloride and water, wherein 10 to 35 parts by weight of sodium chloride are added relative to 100 parts by weight of water to prepare a mixture; and a de-icing agent manufacturing step of mixing a freezing liquid into the mixture, wherein 5 to 30 parts by weight of the freezing liquid are added relative to 100 parts by weight of the mixture to manufacture the de-icing agent.

[0042] To explain the present invention described above in more detail,

[0044] The present invention relates to a liquid de-icing agent capable of preventing black ice from forming on road surfaces during winter and a method for manufacturing the same.

[0046] First of all, the liquid de-icing agent of the present invention is used to prevent road freezing.

[0047] The above-mentioned de-icing agent consists of sodium chloride (NaCl), water, and freezing liquid.

[0049] The above sodium chloride uses high-purity sodium chloride.

[0050] In this invention, solar salt in granular or lump form that has not undergone chemical processing (such as industrial by-products) was used.

[0052] The water mentioned above should be purified water or tap water, provided that it does not contain impurities.

[0054] The above sodium chloride is included in an amount of 10 to 35 parts by weight based on 100 parts by weight of water.

[0055] In the present invention, sodium chloride was included in an amount of 30 parts by weight based on 100 parts by weight of water.

[0057] The above freezing liquid contains 5 to 30 parts by weight based on 100 parts by weight of a mixture of sodium chloride and water.

[0058] In the present invention, 10 parts by weight of the freezing liquid were included based on 100 parts by weight of the mixed liquid.

[0060] The above freezing liquid contains 10 to 40 parts by weight of water-based urethane, 20 to 40 parts by weight of water-based acrylic, 1 to 10 parts by weight of aerogel, and 10 to 40 parts by weight of silica sol.

[0062] When applying the above freezing liquid to the present invention, 25 parts by weight of water-based urethane, 30 parts by weight of water-based acrylic, 4 parts by weight of aerogel, and 15 parts by weight of silica sol were appropriate.

[0064] The following are the experimental results using the de-icing agent containing the freezing liquid of the present invention.

[0066] [Figure 1]

[0067]

[0068] Figure 1 shows water frozen at minus 19 degrees.

[0070] [Figure 2]

[0071]

[0072] Figure 2 shows the liquid de-icing agent of the present invention applied to the frozen part (upper part) of Figure 1, and it can be seen that the frozen part melts (de-icing).

[0074] [Figure 3]

[0075]

[0076] Figure 3 is a photograph of the melted (de-iced) liquid de-icing agent from Figure 2 after being placed at minus 19 degrees for 24 hours, and it was confirmed that it did not freeze.

[0078] In addition, regarding a de-icing agent for preventing freezing of roads, the de-icing agent comprises 100 parts by weight of water, 10 to 40 parts by weight of silica sol, 0.1 to 2 parts by weight of sodium oxide, 0.5 to 2 parts by weight of sodium silicate, 0.5 to 2 parts by weight of 3-aminopropyltrimethoxysilane, and 0.1 to 0.5 parts by weight of aerogel.

[0080] The use of the aforementioned de-icing agent reduces salt runoff, prevents fine dust and road erosion, and also offers the potential for reducing toxicity.

[0082] Conventional de-icing agents (sodium chloride, calcium chloride, etc.) flow into river water and soil when spread on roads, causing water and soil pollution. However, when using a sodium silicate-based binder, salt is not easily washed away, which reduces the spread of salt, and pollution is mitigated because less chloride is required compared to conventional de-icing agents.

[0084] In addition, some de-icing agents (especially CaCl₂ and MgCl₂) promote corrosion of roads and vehicles, and if sodium silicate binder acts as a protective barrier, it may mitigate corrosion of roads and vehicles.

[0085] This may suppress the generation of fine dust and potentially reduce the amount of dust that is blown away in powder form even after drying.

[0087] In addition, sodium silicate is non-toxic and has a low potential for biological accumulation.

[0088] It is possible that it has lower toxicity compared to some harmful de-icing agents (CaCl₂, MgCl₂, KAc, etc.), and that its impact on aquatic ecosystems is also likely to be less than that of existing sodium chloride de-icing agents.

[0090] In addition, other embodiments of the above-mentioned freezing liquid include,

[0091] A freezing liquid containing 25 to 35 parts by weight of water-based urethane, 2 to 4 parts by weight of titanium, 2 to 4 parts by weight of silica, 15 to 25 parts by weight of water-based acrylic, 5.5 to 7.5 parts by weight of lithium, 5 to 7 parts by weight of ceramic, 2 to 6 parts by weight of ammonia, 4 to 8 parts by weight of melamine, 10 to 20 parts by weight of water, and 5.5 to 7.5 parts by weight of sodium may also be used.

[0093] When the above freezing liquid is applied to the present invention, it consists of 30 parts by weight of water-based urethane, 3 parts by weight of titanium, 3 parts by weight of silica, 20 parts by weight of water-based acrylic, 6.5 parts by weight of lithium, 6 parts by weight of ceramic, 4 parts by weight of ammonia, 6 parts by weight of melamine, 15 parts by weight of water, and 6.5 parts by weight of sodium.

[0095] The above-mentioned de-icing agent contains coffee grounds, comprising 5 to 25 parts by weight based on 100 parts by weight of the de-icing agent.

[0096] The above coffee grounds are dried by natural drying, using a dryer, or using a press, depending on the presence or absence of moisture; however, when using a dryer, coffee grounds dried at a temperature of 120 to 160 degrees for 3 to 5 hours are additionally included in an amount of 20 to 55 parts by weight relative to 100 parts by weight of the total de-icing agent.

[0097] With the inclusion of the above coffee grounds, the liquid de-icing agent is first mixed.

[0099] In addition, the above-mentioned de-icing agent includes coconut long fibers, comprising 2 to 8 parts by weight based on 100 parts by weight of the de-icing agent.

[0101] The above coconut long fibers undergo a first mixing process, and then a second mixing process is performed.

[0103] In the case of the first and second mixing of the above coffee grounds and coconut long fibers, the mixing is performed individually or, when mixed together, the first and second mixing are performed as described above.

[0105] The above-mentioned de-icing agent includes pine needle clay balls, comprising 10 to 30 parts by weight based on 100 parts by weight of the de-icing agent.

[0106] The above pine needle and red clay balls are prepared by preparing pine needles with a size of 2–5 mm in an amount of 65–70% of the total weight of the balls, red clay with a size of 250–500 mesh in an amount of 10% of the total weight of the balls, washing and juicing separate pine needles, storing the extracted juice at a temperature of 10–20°C for 3–5 hours to remove pine needle sediment, preparing a clear pine needle juice supernatant in an amount of 50–60% of the total weight of glutinous rice paste, and preparing glutinous rice flour in an amount of 40–50% of the total weight of the glutinous rice paste, mixing them together, and heating at 100°C for 30–50 minutes to prepare a glutinous rice paste in a thick, adhesive-like state in an amount of 20–25% of the total weight of the balls, then mixing the above pine needles, glutinous rice paste, and red clay to make a dough using a dough mixer for 10–30 minutes, and using a ball generator or pill maker to It is complete.
