Description

Technology Field

[0001] The present invention relates to a road anti-slip material comprising an anti-slip pattern protruding from a floor surface and a composition for an anti-slip pattern. Background Technology

[0002] Generally, anti-slip pavement refers to a facility installed to promote safe driving of vehicles, etc., by increasing the skid resistance of the pavement surface in places where the skid resistance of the road surface is low or where the horizontal and vertical alignment of the road is poor, in order to shorten the braking distance of vehicles or to prevent traffic accidents by increasing the visibility of roads where people walk, such as school routes and crosswalks.

[0003] The purpose of such anti-slip pavements is to enhance friction by installing them in sections where the required level of skid resistance cannot be secured due to the road's geometry and traffic characteristics. In other words, when the skid resistance of the pavement drops below a certain level across the entire section as the road's service life increases, the road is repaired using anti-slip paint compositions to fundamentally increase skid resistance from a maintenance perspective. Recently, the demand for these anti-slip paint compositions has been surging as they are being applied not only to roads but also to places prone to slipping while walking, such as building rooftops, outdoor parking lots, and parks.

[0004] In particular, anti-slip road patterns are being installed on roads to increase the friction between vehicle wheels and the road surface. Previously, road patterns were formed by using equipment to create multiple grooves on the road or by installing uneven surfaces including protrusions, or by placing an intaglio mold on the road, filling the mold with a composition for anti-slip road patterns, and then removing the mold. However, existing anti-slip patterns have problems such as significantly reduced slip resistance due to the wear and detachment of aggregates caused by continuous vehicle impact or driving, reduced ride comfort due to excessive noise and vibration caused by the use of coarse aggregates to increase slip resistance, and high installation costs.

[0005] Furthermore, road anti-slip patterns produced using molds have problems such as defects occurring because the pattern does not adhere sufficiently to the road surface, or the pattern flowing before curing, if the composition for the anti-slip pattern does not possess appropriate viscosity and flexibility. Accordingly, the inventors have developed a road anti-slip material that forms a road anti-slip pattern including a V-shape protruding from the surface, allows for easy viscosity control so that it can be manufactured in the form of a pattern using a mold or pattern paper, improves adhesion strength with the surface, and prevents easy detachment, thereby arriving at the present invention.

Specific details for implementing the invention

[0031] The following describes in detail an anti-slip material for roads and a composition for an anti-slip pattern including an anti-slip pattern protruding from a floor surface according to the present invention. The drawings presented below are provided as examples to ensure that the concept of the present invention is sufficiently conveyed to those skilled in the art. Accordingly, the present invention is not limited to the drawings presented below and may be embodied in other forms, and the drawings presented below may be exaggerated to clarify the concept of the present invention. Unless otherwise defined, technical and scientific terms used herewith have the meanings commonly understood by those skilled in the art to which this invention pertains, and descriptions of known functions and configurations that could unnecessarily obscure the essence of the present invention are omitted in the following description and attached drawings.

[0032] One aspect of the present invention relates to a road anti-slip material having an anti-slip pattern (200) formed protruding from a bottom surface (100) and including a V-shape, wherein the anti-slip pattern is formed in a plurality of or more, and the anti-slip pattern is manufactured from an anti-slip pattern composition comprising an acrylic resin, a thickener, a fluidity-regulating additive, and a tackifier.

[0033] The anti-slip pattern (200) including the above V-shape is,

[0034] A V-shaped protruding pattern (210) that is integrally formed;

[0035] A pattern (220) in which a part of the protruding circle is V-shaped;

[0036] A pattern (230) in which two identical protruding projections are symmetrically adjacent to each other and protrude in a V-shape; and

[0037] A protruding pattern (240) in which two of three protruding protrusions having the same width and shape form a V shape and one protruding protrusion is adjacent to form a Y shape;

[0038] It may be one or more types selected from among.

[0039] Referring to FIG. 1, the anti-slip material for roads may have an anti-slip pattern (200) installed on a floor surface (100) that is formed by protruding from the floor surface and including a V-shape, and may be an anti-slip material for roads in which a plurality of anti-slip patterns are formed using a mold or pattern paper.

[0040] Referring to FIGS. 2 and 3, the pattern (210) (hereinafter, pattern (210)) which is an integrally protruding V-shaped pattern among the above anti-slip patterns including the V-shaped pattern may be formed by protruding on the bottom surface (100) and having a plurality of or more integrally formed V-shaped patterns.

[0041] Referring to FIGS. 4 and 5, the pattern (220) (hereinafter, pattern (220)) in which a protruding part of a circular shape among the anti-slip patterns including the above V-shape has a V-shaped indentation may be formed by having a plurality of patterns in which a part of a circular shape has a V-shaped indentation.

[0042] Referring to FIGS. 6 and 7, the pattern (230) (hereinafter, pattern (230)) in which two identical protruding projections are symmetrically adjacent to each other and protrude in a V-shape among the anti-slip patterns including the above V-shape may be formed by having a plurality of patterns in which two identical protruding plates are symmetrically adjacent to each other and protrude in a V-shape.

[0043] Referring to FIGS. 8 and 9, the protruding pattern (240) (hereinafter, pattern (240)), which is an anti-slip pattern including the above V-shape, may be formed by two of three protruding protrusions having the same width and shape to form a V-shape and one protruding protrusion forming a Y-shape adjacent to each other, and there may be a plurality of protruding patterns formed by two of three protruding protrusions having the same width and shape to form a V-shape and one protruding protrusion forming a Y-shape adjacent to each other.

[0044] The anti-slip pattern including the above V-shape may be one or more selected from the above pattern (210), pattern (220), pattern (230) and pattern (240).

[0045] In addition, the above-mentioned plurality of anti-slip patterns are characterized by being manufactured using an anti-slip pattern composition comprising an acrylic resin, a thickener, a fluidity-regulating additive, and a tackifier. Since viscosity can be easily controlled, it is possible to manufacture the pattern using a mold or pattern paper, thereby forming an anti-slip pattern on a road surface. Furthermore, the composition for anti-slip patterns can be provided, which has excellent durability and minimizes wear of the pattern, allowing it to be maintained for a long period.

[0046] The following describes each component of the anti-slip pattern composition according to an example of the present invention in more detail.

[0047] The above acrylic resin may be one or more selected from methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, isopropyl acrylate, isopropyl methacrylate, butyl acrylate, butyl methacrylate, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, lauryl acrylate, lauryl methacrylate, glycidyl acrylate, glycidyl methacrylate, acrylic acid, methacrylic acid, acrylonitrile, and methacrylonitrile, and it is more preferable to use methyl methacrylate (MMA) resin.

[0048] Methyl methacrylate resin is a resin that is typically mixed directly at construction and civil engineering sites and exhibits physical properties through chemical reactions in a relatively short time. It has the advantage of curing rapidly to form a film not only at room temperature (25 ℃) but also at low temperatures (-35 ℃), and allows for operation even at minus 30 degrees. It possesses strong characteristics in terms of wear resistance, corrosion resistance, weather resistance, and resistance to deterioration. It is particularly suitable for road paving as it allows for manual application using tools such as trowels and rollers, as well as mechanized spray application, while also having the characteristic of producing almost no toxic gases upon ignition.

[0049] Anti-slip paving materials using methyl methacrylate resin have a problem in that cracks easily occur due to brittleness, which is one of the characteristics of methyl methacrylate resin. In addition, anti-slip paving materials using methyl methacrylate resin are reactive products that use a mixture of a main component and a curing agent, and there is a problem in that the curing speed varies depending on the ambient temperature during construction or the passage of time, so while a good curing speed of about 1 hour is observed in relatively high-temperature environments such as summer, the curing speed is significantly slowed down to about 2 to 3 hours in low-temperature environments of about 5°C or lower such as winter.

[0050] The anti-slip pattern composition of the present invention is based on methyl methacrylate resin, but is manufactured in a gel form to solve the problems of brittleness and cracking of methyl methacrylate.

[0051] A thickener is used to control the viscosity of the composition and prevent sedimentation for workability. It is preferable to use cellulose as the thickener, as it is advantageous for forming a three-dimensional network structure within the composition. The thickener can be added in an amount of 0.6 to 5 parts by weight per 100 parts by weight of the acrylic resin; if the amount is less than 0.6 parts by weight, there is no thickening effect, and if it exceeds 5 parts by weight, the viscosity of the composition may increase excessively.

[0052] A fluidity-regulating additive is added to impart fluidity to the composition by controlling the viscosity increased by a thickener. The inclusion of the fluidity-regulating additive imparts thixotropy to the composition for anti-slip patterns to prevent sedimentation and maintain a constant viscosity during the pot life. Furthermore, by manufacturing it in a fluid gel form, it is possible to achieve a viscosity suitable for manufacturing anti-slip patterns for roads. Specifically, the fluidity-regulating additive may be a urea-based compound and may be added in an amount of 1 to 5 parts by weight per 100 parts by weight of the acrylic resin. If the amount is less than 1 part by weight, it is difficult to maintain a constant viscosity of the composition during the pot life, and solidification may occur, making pattern formation difficult. If the amount exceeds 5 parts by weight, the viscosity becomes too low, which increases flowability during pattern manufacturing, making it difficult to cure into a pattern shape and potentially reducing workability.

[0053] A tackifier is added to improve the adhesion between the floor surface and the anti-slip pattern of the road surface, and may be one or more selected from phenolic resin, polytherpan resin, and petroleum resin. More specifically, phenolic resin may be used, and the tackifier may be added in a range of 3 to 20 parts by weight per 100 parts by weight of the acrylic resin. If it is included in less than 3 parts by weight, there is a problem with reduced slip resistance, and if it is included in more than 20 parts by weight, a decrease in wear resistance may occur, and peeling of the road pattern may occur when traffic is opened after the coating work.

[0054] The above anti-slip pattern composition may further include an inorganic filler, silica sand, a curing accelerator, and a reaction initiator.

[0055] The inorganic filler may be calcium carbonate and may be used in an amount determined within the range of 60 to 150 parts by weight relative to 100 parts by weight of the acrylic resin to increase adhesion with the bottom surface and enhance wear resistance.

[0056] The silica sand is a composition that increases the durability of the road by having high wear resistance and increases slip resistance by lowering the degree of slipperiness of the road surface. It can be selected from materials that have a high coefficient of friction and can provide high surface roughness on the surface of the paving material, and silica sand with a particle size of 0.3 to 7.0 mm is preferred. The silica sand may be included in an amount of 30 to 150 parts by weight; if it is less than 30 parts by weight, the anti-slip effect is reduced, and if it exceeds 150 parts by weight, noise and vibration may be induced during driving due to the silica sand.

[0057] Curing accelerators are used in combination with reaction initiators to promote the reaction of acrylic resins and have effects such as reducing toxicity and odor. As the above curing accelerator, one or more selected from amine compounds and toluidine compounds may be used. Specifically, as the above amine compounds, triethylenediamine, triethylamine, tetramethylenediamine, tri-n-butylamine, N,N-dimethylethanolamine, dimethylimidazole, N-ethyl-N-hydroxyethylaniline, and N,N-dimethylaniline may be used; as the above toluidine compounds, one or more selected from N,N-bis(2-hydroxyethyl)p-toluidine, N,N-dimethyl-p-toluidine, and N,N-di(2-hydroxypropyl)p-toluidine may be used. Specifically, N,N-di(2-hydroxyethyl)p-toluidine may be used, and the curing accelerator is suitable for mixing with the reaction initiator when included in an amount of 0.6 to 5 parts by weight per 100 parts by weight of the acrylic resin.

[0058] The reaction initiator may be one or more selected from the group consisting of benzoyl peroxide, lauryl peroxide, acetyl peroxide, and octyl peroxide, and specifically, benzoyl peroxide may be used, and it is preferable to include 3 to 10 parts by weight based on 100 parts by weight of the acrylic resin. If the content of the reaction initiator is less than 3 parts by weight, curing does not occur sufficiently, and if it exceeds 10 parts by weight, the pot life may be shortened due to rapid curing, which is undesirable.

[0059] In addition, the above anti-slip pattern composition may include additives such as softeners, coloring pigments, UV stabilizers, fluorescent whitening agents, modifiers, defoaming agents, leveling agents, wetting agents, flame retardants, matting agents, and antioxidants as needed, and the specific types and amounts may be selected within a conventional range.

[0060] The above anti-slip pattern composition may further include glass powder, which serves to increase the reflectivity to light emitted from automobile headlights and improve visibility. The content may be added in an amount of 15 to 100 parts by weight, and a particle size of 150 to 500 μm may be used. Within this range, the particle size and content of the glass powder selected are evenly dispersed in the aforementioned composition, and viscosity control is easy.

[0061] The above floor surface may be one or more types selected from asphalt and concrete.

[0062] The above-described anti-slip pattern composition may be a two-component composition prepared by mixing a main component comprising an acrylic resin, a thickener, a fluidity-regulating additive, a tackifier, an inorganic filler, silica sand, and a curing accelerator; and a curing agent comprising the reaction initiator.

[0063] In addition, the above anti-slip pattern may be manufactured by including the steps of: a) preparing a composition for an anti-slip pattern; and b) forming a road anti-slip pattern on a floor surface using the composition for an anti-slip pattern.

[0064] Step a) above is a step of preparing a composition for an anti-slip pattern, wherein a main component is prepared by mixing the acrylic resin, a thickener, a fluidity-regulating additive, a tackifier, an inorganic filler, silica sand, and a curing accelerator, and a curing agent including a reaction initiator is prepared.

[0065] The components and content of the above subject and curing agent are as described above in the anti-slip pattern composition, so a redundant explanation is omitted.

[0066] The above step b) may be a step selected from among: step b-1) of manufacturing a semi-finished product of a semi-finished product of a non-finished pattern by injecting the composition for the non-finished pattern into a mold and curing it, and then removing the mold to form a non-finished pattern by attaching the semi-finished product of the non-finished pattern to a floor surface; and step b-2) of forming a non-finished pattern by placing a pattern paper on a floor surface, applying the composition for the non-finished pattern, and curing it.

[0067] Step b-1) above is a step of manufacturing an anti-slip pattern semi-finished product by placing a mold on a pattern support, injecting the anti-slip pattern composition into the mold and curing it, and then removing the mold. The pattern support may be one or more selected from water-soluble nonwoven fabric, glass fiber mesh, polyester fiber mesh, and carbon fiber mesh. The mold may be one or more selected from iron, stainless steel, Teflon, and aluminum, but is not limited thereto as long as it is a type of mold commonly used. When manufacturing the semi-finished product, a release agent may be applied. A mold with the release agent applied is placed on the pattern support, and the anti-slip pattern composition is injected into a through hole to a thickness of 0.5 to 10 mm and cured for 1 to 2 hours. The composition cured in this way can be easily cured into a pattern shape by the pattern support, and the durability and adhesive retention of the anti-slip pattern can be improved thereafter.

[0068] Afterward, the anti-slip pattern semi-finished product, from which the mold has been removed from the cured composition, is attached to the floor surface. The floor surface may be one or more types selected from asphalt and concrete. If the floor surface is asphalt, an adhesive may be applied and the anti-slip pattern semi-finished product may be attached to construct the anti-slip pattern. If the floor surface is concrete, an anti-slip pattern may be manufactured by applying a primer, then applying an adhesive, and attaching the anti-slip pattern semi-finished product.

[0069] Step b-2) above may involve placing a pattern sheet directly on the floor surface, applying the anti-slip pattern composition by spraying, and curing to form an anti-slip pattern. The pattern sheet may be a pattern sheet with a desired pattern engraved thereon.

[0070] Step b) above can be selected from Step b-1) or Step b-2) depending on the construction site conditions.

[0071] Hereinafter, the anti-slip material for roads and the composition for the anti-slip pattern, including an anti-slip pattern protruding from a floor surface according to the present invention, will be described in more detail through examples. However, the following examples are merely for reference to explain the present invention in detail, and the present invention is not limited thereto and can be implemented in various forms.

[0072] Furthermore, unless otherwise defined, all technical and scientific terms have the same meaning as generally understood by one of the art to which the present invention pertains. The terms used in the description herein are merely for the purpose of effectively describing specific embodiments and are not intended to limit the present invention.

[0109] Comparative Example 1 did not contain a fluidity-controlling additive, and due to its high viscosity, it could not form a gel and pattern formation was impossible.

[0110] Preparation Examples 2 to 4 are prepared in which the fluidity-regulating additive is added in an amount of 1 to 5 parts by weight per 100 parts by weight of acrylic resin, and it can be seen that the slip resistance and wear resistance characteristics are significantly improved compared to Preparation Example 1, in which the fluidity-regulating additive is added in an amount of less than 1 part by weight, or Preparation Example 5, in which the fluidity-regulating additive is added in an amount of more than 5 parts by weight.

[0111] Preparation Example 6 contained 1 part by weight of a tackifier, and while the adhesive strength was improved compared to Comparative Example 2, in which no tackifier was added, the slip resistance and wear resistance were not improved. Preparation Examples 7 to 9 contained 3 to 20 parts by weight of a tackifier, which improved the slip resistance and wear resistance, and the adhesive strength was excellent when the tackifier content was 20 parts by weight. However, Preparation Example 10, which contained more than 20 parts by weight of a tackifier, showed delamination of the specimen and poor adhesion.

[0112] In this way, a gel-type composition having a viscosity suitable for manufacturing road patterns can be prepared in the range of 0.6 to 5 parts by weight of the thickener and 1 to 5 parts by weight of the fluidity-regulating additive per 100 parts by weight of the acrylic resin, and an anti-slip pattern using this has achieved a slip resistance of 95 BPN or higher when dry, a slip resistance of 91 BPN or higher when wet, and a wear resistance of 100 mg or lower.

[0113] In addition, it was confirmed that a road anti-slip material including a road anti-slip pattern with an adhesive strength of 1.7 MPa or higher can be manufactured when the content of the above-mentioned tackifier is in the range of 3 to 20 parts by weight per 100 parts by weight of acrylic resin.
