Description

Anti-slip paving material containing an anti-freezing additive and method for manufacturing the same

[0001] The present invention relates to an anti-slip paving material comprising an anti-freezing additive and a method for manufacturing the same.

[0002]

[0003] Currently, road icing is recognized as one of the major causes of traffic accidents and road damage during the winter. When ice forms on roads due to low temperatures following snow or rain, vehicle skidding increases, raising the risk of traffic accidents. To prevent this, various anti-icing technologies are being developed.

[0004] Conventional anti-icing technologies involve the application of de-icing or anti-icing agents using chlorides (such as sodium chloride and calcium chloride). While chloride-based de-icing agents are highly effective in suppressing freezing, they present environmental issues such as soil and groundwater contamination and vehicle corrosion, as well as metal corrosion problems. In particular, chlorides have limitations in that they do not remain on the road surface for long periods and are easily washed away by rain or snow, causing their de-icing effectiveness to rapidly decline over time.

[0005] To address these issues, various phase transition materials (PCMs) and synthetic oil-based technologies have been introduced. Phase transition materials (PCMs), which are energy storage phase change materials, possess high energy storage density and offer the advantages of minimal temperature fluctuations during heat absorption and release, as well as easy process control. Therefore, applying them to road pavements allows for sustained anti-freezing effects through their heat storage and release capabilities. Since PCMs change their physical state and possess the characteristic of absorbing or releasing latent heat within a specific temperature range, they absorb and store a large amount of latent heat during the melting process when transitioning from solid to liquid; conversely, when the PCM cools and reaches its cooling point, it releases the stored latent heat during the solidification process.

[0006] However, phase transition materials also require long-term performance maintenance on roads and resistance to external factors (moisture, heat, etc.). Furthermore, it is important to possess low toxicity, an appropriate phase transition temperature, high latent heat capacity, stable performance, excellent phase transition repeatability, small expansion and contraction rates, superior thermal conductivity, low cost, and easy processability of the raw materials.

[0007] The present invention proposes a technology that imparts an anti-icing function to a road surface using microcapsules of three or more types of anti-icing additive materials. By filling the anti-icing additive microcapsules into a porous structure, the technology enables the stable preservation and gradual release of anti-icing components such as chlorides, alcohols, synthetic oils, and paraffin waxes, thereby allowing for a long-term effect.

[0008]

[0009] The present invention proposes a technology that simultaneously achieves road icing prevention and enhanced slip resistance, and can provide high road safety without changing the mixing ratio of existing anti-slip paving materials.

[0010] In particular, the main objective is to provide an anti-slip paving material with excellent durability and anti-icing effects, and a method for manufacturing the same, by utilizing an anti-icing additive that can operate stably even under various temperature changes, thereby maintaining the long-term effectiveness of the product and reducing road maintenance costs.

[0015] In one embodiment of the present invention, the phase change temperature of the sulfide and paraffin is lower than the phase change temperature of the chloride.

[0016] In one embodiment of the present invention, the chloride is selected from sodium chloride, calcium chloride, and magnesium chloride.

[0020]

[0021] The anti-slip paving material of the present invention has enhanced flexibility and durability to minimize peeling and crack formation, continuously maintains its slip resistance function even with coating damage caused by vehicle wheels, and provides an anti-icing effect for a long period, thereby stably maintaining road performance and reducing maintenance costs.

[0022] In addition, chlorides, sulfides, paraffins, and alcohols act complementarily, so that the antifreeze additive is continuously supplied through capillary action, thereby maintaining the antifreeze effect for a long time and keeping the freezing point of the road surface below -16℃, and after a single application of the anti-slip paving material of the present invention, it can provide a continuous effect for 2 to 3 years without the need for additional treatment.

[0023] The anti-slip paving material of the present invention can minimize the black ice phenomenon even at -5℃ or below, and can prevent traffic accidents by preventing freezing in shaded areas and mountainous regions.

[0027]

[0028] As an anti-slip paving material containing three or more types of anti-freezing additives,

[0030] (A) 5~10 wt% chloride;

[0031] (B) 5-10% by weight of sulfides and paraffins; and

[0032] (C) Contains 10 to 20 weight percent of alcohol,

[0033] The weight ratio of the above components (A): (B): (C) is 1: 1: 2~3, and

[0034] The above chloride is a microcapsule fine particle powder,

[0035] The above sulfide is a water-insoluble particle of 1.2 mm or less, and the alcohol is a liquid, providing an anti-slip paving material.

[0036]

[0037] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0038] The advantages and features of the present invention and the method for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0039] However, the present invention is not limited by the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0040] In addition, in describing the present invention, if it is determined that related known technologies, etc., may obscure the essence of the present invention, a detailed explanation thereof will be omitted.

[0041] One embodiment of the present invention provides an anti-slip paving material comprising three or more types of anti-freezing additives.

[0042] Specifically, the anti-slip paving material of the present invention comprises at least three types of the following anti-freezing additives based on a total amount of 100% by weight.

[0043] (A) Chloride: 5~10 wt%

[0044] (B) Sulfides and paraffins: 5~10 wt%

[0045] (C) Alcohol: 10~20 wt%

[0046] At this time, the weight ratio of components (A):(B):(C) included in the anti-slip paving material is composed of 1:1:2~3, the chloride is a microcapsule fine particle powder, and the sulfide is an insoluble particle of 1.2 mm or less.

[0047] The anti-slip paving material of the present invention includes three types of anti-freezing additives, namely chloride, sulfide, paraffin, and alcohol, and uses these to provide an anti-freezing function.

[0048] The three types of materials mentioned above are evenly distributed within the anti-slip paving material and operate, and the specific mechanism of operation upon application is as follows.

[0049] When the anti-slip paving material of the present invention is applied to a road surface, heat is released during the process of leaching chlorides onto the surface of the anti-slip paving material by capillary action caused by the load of vehicles on the road. As a result, the freezing point of the road is lowered, and the anti-freezing performance of the road surface is exhibited. Meanwhile, micro-pores are formed inside the anti-slip paving material due to the leaching of chlorides. Sulfates and paraffins that have turned into a liquid state and are dispersed inside the anti-slip paving material move into these micro-pores and then convert back into a solid at room temperature, thereby enabling the continuous performance of the anti-freezing function. In this way, the anti-slip paving material of the present invention not only lowers the freezing point of the surface but also improves the durability and lifespan characteristics of the anti-slip paving material by resupplying internal anti-freezing additives through capillary action even after consumption.

[0050]

[0051] Below, we will examine in detail the anti-slip paving material according to the present invention and the method for manufacturing the same.

[0052]

[0053] (A) Chloride

[0054] The present invention includes a chloride with excellent anti-freezing effect. The chloride leaches out to the outside of the anti-slip packaging material at 0°C and performs an anti-freezing function.

[0055] Sodium chloride, calcium chloride, magnesium chloride, etc., can be used as these substances, and chlorides perform an antifreeze function from -15℃ to -20℃ below 0℃.

[0056] Sodium chloride has a relatively high solubility in water, approximately 357g per 1000g of water (at 25°C). Calcium chloride has a solubility of approximately 745g per 1000g of water (at 20°C). As such, the raw materials that exhibit the anti-freezing effect each have different solubility in water.

[0057] The above sodium chloride or calcium chloride is a water-soluble inorganic salt with excellent hygroscopic and water-retaining properties, and has the effect of melting snow or ice by absorbing moisture.

[0058] In one embodiment of the present invention, the chloride may take the form of a microcapsule fine particle powder. The chloride produced through the micro-encapsulation process exhibits various advantages, such as improved heat transfer capacity due to an increased surface area capable of heat exchange, reduced reactivity with the surrounding environment within the application target, and reduced expansion pressure due to volume change. Furthermore, due to its small particle size, it can be directly utilized in powder form, and the risk of leakage from the application target can be significantly reduced as there is little concern about the destruction of the outer shell.

[0059] In one embodiment of the present invention, the microcapsule fine particle powder has an average diameter of about 10 to 100 μm, and a polymer (e.g., polyurethane, melamine resin) or an inorganic material (e.g., silica, alumina) may be used as the outer wall material. This microcapsule structure is uniformly distributed inside the packaging material. Since the method of manufacturing the microcapsule fine particle powder is manufactured using a method widely known in the art, a detailed description is omitted.

[0060] The above chloride may be included in an amount of 10 to 20 weight percent with respect to 100 weight percent of the above anti-slip paving material.

[0061]

[0062] (B) Sulfides and paraffins

[0063] Conventional chlorides have been used as antifreeze additives in anti-slip paving materials; however, they had limitations as they were easily leached out and lost due to external environmental factors such as rain and snow. Consequently, even if their performance was excellent, this led to problems such as performance degradation or a shortened lifespan of the antifreeze function over time. In particular, if chlorides leached out and were lost prematurely in environments such as the summer rainy season, the issue of reduced antifreeze performance became even more pronounced during the winter.

[0064] To solve the above problem, the present invention additionally includes sulfides and paraffins, which play an important role in maintaining the anti-freezing function for a long time. Sulfates and paraffins are anti-freezing additives with freezing point depression properties; they are insoluble in water and serve to increase the flexibility and hardness of the coating film. The sulfides and paraffins used in the present invention complement the anti-freezing performance by filling the micropores created after the chloride is consumed through phase change. The sulfides and paraffins operate efficiently during the process of filling the pores, thereby enabling the continuous maintenance of the anti-freezing effect.

[0065] In the present invention, the sulfide is an insoluble particle of 1.2 mm or less. Since the sulfide does not dissolve in water, it can maintain anti-freezing performance for a long period. Therefore, when fine particulate voids are generated within the anti-slip packaging due to the leaching of chloride, sulfides of 1.2 mm or less and paraffin flow into the generated fine particulate voids. Subsequently, they fill the fine particulate voids and settle stably.

[0066] As a result, even if chlorides are continuously leached out and lost, sulfides and paraffins fill the void, allowing the antifreeze effect to be maintained.

[0067] Furthermore, in the present invention, the sulfide serves not only to simply fill voids but also to increase the tensile strength of the anti-slip paving material. That is, by preventing voids caused by the leaching of chlorides from leading to structural cracks in the anti-slip paving material, it has the effect of improving the durability of the paving material.

[0068] In the present invention, the sulfide may be zinc sulfide (ZnS), iron sulfide (FeS), etc.

[0069] The above sulfide can maximize the anti-freezing effect at an appropriate temperature by controlling its reactivity with water. In one embodiment of the present invention, the particle size of the sulfide may be 1.2 mm or less, approximately 0.8 mm to 1.2 mm. In addition, the sulfide does not dissolve in water, thereby preventing performance degradation or loss of the anti-slip paving material.

[0070] The above paraffin has the advantage of excellent volume stability due to repeated stable and low vapor pressure.

[0071] Representative paraffinic materials that can be used to prevent black ice include n-tetradecane (C14), n-pentadecaine (C15), n-hexadecane (C16), and n-heptadecaine (C17), which can be utilized in various ways depending on their phase transition temperatures and physical properties, but are not limited thereto.

[0072] The anti-slip paving material of the present invention may comprise 5 to 10 weight percent of sulfides and paraffins based on 100 weight percent of the anti-slip paving material.

[0073]

[0074] (C) Alcohol

[0075] The above alcohol is in liquid form. The alcohol provides an anti-icing function on the road surface while simultaneously providing physical stability to the paving material. The alcohol has strong thermal conductivity and reacts sensitively to temperature changes, enabling it to effectively achieve anti-icing performance.

[0076] Examples of alcohols used in the present invention include ethanol, propanol, butanol, pentanol, etc., and these substances may be used alone or in combination. The types of alcohol-based substances that can be used are not limited thereto.

[0077] Alcohol has high solubility in water and absorbs or releases heat depending on changes in external temperature. These characteristics enhance the anti-icing effect on road surfaces and contribute to maintaining anti-icing performance for an extended period.

[0078] Alcohol prevents freezing by releasing heat in low-temperature environments on road surfaces, and regulates the consumption of anti-freezing additives by triggering an endothermic reaction when the external temperature rises. Additionally, alcohol is uniformly distributed across the surface of the pavement, further enhancing the anti-freezing effect.

[0079] The anti-slip paving material of the present invention may contain 10 to 20 weight percent of alcohol per 100 weight percent of the anti-slip paving material.

[0080]

[0081] In one embodiment of the present invention, the aforementioned (A) chloride, (B) sulfide and paraffin, and (C) alcohol may satisfy a content ratio of 1:1:2 to 3, preferably having a content ratio of 1:1:2. When the above range is satisfied, it may have an antifreeze effect even at a low temperature of -16℃.

[0082] In one embodiment of the present invention, the anti-slip paving material may comprise, with respect to 100% by weight of the anti-slip paving material, (A) 10-20% by weight of chloride; (B) 10-20% by weight of sulfide and paraffin; (C) 10-20% by weight of alcohol; (D) 20-40% by weight of modified methyl methacrylate (MMA); (E) 10-30% by weight of calcium carbonate; (F) 10-20% by weight of silica; (G) 1-3% by weight of anti-sedimentation agent; (H) 3-5% by weight of pigment; (I) 5-10% by weight of aggregate; and (J) 4-8% by weight of curing agent (BPO).

[0083] The modified methyl methacrylate (MMA) resin composition in the present invention serves as a binder, improving durability and adhesion, and enabling the road paving material to remain crack-free for a long period. By using the modified MMA form, flexibility and impact resistance are improved compared to conventional MMA, and to this end, the modified MMA resin composition may include the following monomers.

[0084] As the above-mentioned reactive monomers, 2-ethylhexyl acrylate (2-EHA), 2-hydroxyethyl acrylate (2-HEA), 2-hydroxyethyl methacrylate (2-HEMA), n-butyl acrylate (n-BA), acrylic acid (AA), methacrylic acid (MAA), vinyl acetate, acrylamide, glycidyl methacrylate (GMA), etc., may be used. In some cases, the above-mentioned monomers may be used alone, but they may also be mixed in various combinations to design composition characteristics having various glass transition temperatures.

[0085] Calcium carbonate acts as a filler in packaging materials and contributes to increasing mechanical strength. With its low unit cost and high durability, it simultaneously improves the economic efficiency and performance of packaging materials, and provides structural stability by being uniformly dispersed within the anti-slip paving material.

[0086] Silica is a key additive that enhances the strength and durability of packaging materials. It provides additional anti-slip functionality and extends the lifespan by reducing the rate of wear on the packaging material. Silica also serves as an anti-sedimentation agent and contributes to maintaining the physical uniformity of the packaging material. The anti-sedimentation agent in this invention helps ensure that each component is uniformly dispersed during the manufacturing process and use of the packaging material. Silica-based materials or polymer-based additives may be used as anti-sedimentation agents.

[0087] The pigment in the present invention is used to control the color and improve the appearance quality of the anti-slip paving material, and mainly comprises inorganic pigments (e.g., iron oxide, titanium oxide, etc.). The pigment is designed to have durability under external environmental conditions.

[0088] The aggregate in this invention serves as a key material that enhances anti-slip functionality, preventing vehicle slip accidents by increasing surface friction. Usable aggregates include quartz aggregate or other highly durable materials.

[0089] The curing agent in the present invention serves to induce curing by mixing with the main component of the anti-slip paving material and is composed of benzoyl peroxide (BPO). BPO ensures the durability and uniform performance of the paving material by stably and rapidly proceeding with the curing reaction.

[0090]

[0091] Another embodiment of the present invention provides a method for manufacturing an anti-slip paving material, the method comprising the following steps.

[0092] (S1) A primary mixture is prepared by mixing (C) alcohol with a modified methyl methacrylate (MMA) resin composition, and

[0093] (S2) A second mixture is prepared by mixing (B) sulfide and paraffin into the first mixture above, and

[0094] (S3) A tertiary mixture is prepared by mixing (A) chloride into the above secondary mixture, and

[0095] (S4) An anti-slip paving material is manufactured by mixing an anti-sedimentation agent, pigment, calcium carbonate, silica, aggregate, and a curing agent into the above 3rd mixture.

[0096] The above anti-slip paving material comprises, based on a total amount of 100% by weight, (A) chloride 5-10% by weight; (B) sulfide and paraffin-based 5-10% by weight; (C) alcohol-based 10-20% by weight; (D) modified methyl methacrylate (MMA) 20-40% by weight; (E) calcium carbonate 10-30% by weight; (F) silica 10-20% by weight; (G) anti-sedimentation agent 1-3% by weight; (H) pigment 3-5% by weight; (I) aggregate 5-10% by weight; and (J) curing agent (BPO) 4-8% by weight.

[0106] The composition and content ratio of the final anti-slip paving material composition are as shown in Table 1.

[0107] Table 1 below shows that the weight ratio of the above (A): (B): (C) components is 1:1:2.

[0110] Experimental Example

[0111] After manufacturing a paving sheet by applying the anti-slip paving material prepared in the above examples and comparative examples onto a test surface, the anti-slip paving sheet was cut to 100mm x 200mm and used as a test specimen below.

[0112]

[0113] 1) Freezing and thawing experiment

[0114] Test specimens prepared as examples and comparative examples were frozen at -16°C for 12 hours and then thawed at room temperature (15–25°C). The freezing and thawing process was repeated at least 10 times, twice a day. Through this experiment, the freezing status and thawing speed of the anti-slip paving materials of the examples and comparative examples were measured, and the results are listed in Table 2.

[0115] Example Comparative Example - Surface condition of test specimen at -16℃: A very thin ice film formed only on the surface; the entire surface was frozen. - When left at room temperature: Thawing time: Approx. 10 minutes; Approx. 1.5 hours

[0116] 2) Flexibility test

[0117] The results of the flexibility test were evaluated under the following conditions and are shown in [Table 2].

[0118] · Test Equipment: Bending machine for flexibility testing (standard equipment)

[0119] · Test temperature: Room temperature (20±2℃)

[0120] · Bending angle: 20 degrees

[0121] · Bending speed: 30 mm / min

[0122] After the test, the test specimen was classified as "Good" if no cracks occurred, "Average" if cracks occurred, and "Poor" if both cracks and material detachment occurred.

[0126] Figures 1 to 4 are photographs of the example and comparative example specimens after being left for 0 hours, 3 hours, 5 hours, and 7 hours, respectively, in weather conditions of -9℃.

[0127] The snow on the test specimen of the example began to melt after 3 hours and completely thawed after 7 hours. On the other hand, in the case of the comparative example, as shown in Figures 3 and 4, the snow on the surface did not melt even after 5 hours, and after 7 hours, although the snow disappeared, the test specimen itself remained frozen and was confirmed to be unthawed.

[0128]

[0130] To verify the anti-freezing and thawing effects of the present invention, the composition prepared in the above example was applied to the asphalt surface of an actual road to a thickness of 3 to 5 mm. Subsequently, after snow fell at temperatures ranging from -7°C to -15°C, the road surface coated with the anti-slip paving material was observed.

[0131] As can be seen in the multiple photos of Fig. 5, it was confirmed that on the road surface coated with red anti-slip paving material, not only was the snow melted, but the road surface did not freeze. Therefore, the present invention suggests that it has excellent anti-freezing and melting effects.
