Description

Abrasion-resistant room temperature curing lane structure with excellent reflectivity at night rainy weather and its construction method

The present invention relates to a wear resistant room temperature curing lane structure having excellent reflectance at night rainy weather and a construction method thereof, and more specifically, a wear resistant room temperature curing lane structure having excellent reflectance at night rain weather used as an excellent lane applied to roads and It is related to the construction method.

The lane painting can be broadly classified into daytime visibility, nighttime retroreflective performance, and rainy reflection performance. Daytime visibility is typically divided into white and yellow, and by maintaining color, the meaning of regulation is transmitted to the driver, and performance is determined according to the durability of the paint used.

The fusion-type paint is a principle that maintains visibility as it is gradually worn by painting thicker than 2 mm, and the room-temperature cure-type paint is coated with a thin film of 0.6 mm to 1 mm by using a rigid property, but it does not wear well and maintains visibility because it is not worn well. will be.

In order to show visibility at night, not only the color but also the glass particles sprayed with the paint are reflected by the headlights of the vehicle, thereby showing visibility.

The fusion-type paint maintains the night-reflecting performance as the glass grains contained in the paint protrude when the paint wears out due to the abrasive properties, and the room-temperature-curable paint remains untouched by the coated glass grains during the painting and does not fall into the good adhesion. Maintains nightly reflection performance.

In order to form a lane on the road, a normal temperature type lane painting method or a fusion type lane painting method is generally used on a pavement. When the adhesion between the road surface and the paint is poor, such as an asphalt road, the durability of the painted lane is weak, and thus it is inevitable to peel, drop, or wear.

In addition, the road surface of concrete was often weakened due to the alkalinity of the concrete, so that the adhesion of the paint was weakened to promote wear or to discolor by secondary chemical reaction.

On the other hand, in order to increase visibility of the lane at night or on a rainy road, a number of techniques have been developed to spray a bead onto a paint to form a reflective layer.

In Patent No. 10-1327331, a road marking composition in which a curing agent is mixed in a paint subject is applied to a pavement road surface to form a base layer, and a bead is sprayed on the base layer to form a reflective layer, thereby providing durability and visibility at night in rainy weather. Disclosed is a lane and a method for constructing the same, and a technology for a road marking composition used therein.

However, as described above, the prior art is often exposed to the upper portion of the road, and is often dropped by vehicle tire rolling or other external factors, and thus there is still a danger at night or driving in the rain.

The present invention is to solve the problems of the existing technology, while being able to sufficiently exhibit the reflection performance in the water at the time of rain at night, it is possible to prevent the reflector for retroreflective reflection of the vehicle light from the impact of the vehicle wheel is separated or worn. It is to provide a lane structure for curing at room temperature that has excellent reflectivity in rainy weather at night, which is excellent in coloring and constructability, and a construction method therefor.

In order to solve the above problems, the lane structure for hardening at room temperature having excellent reflectance at night rainy weather according to the present invention includes: core beads; Small beads are attached while filling the outer peripheral surface of the core beads; A piece of photoluminescent aggregate mixed with the core beads to which the small beads are attached to support the core beads; And a core bead to which the small beads are attached and a coating material to which the pieces of photoluminescent aggregate are sprayed.

The small beads may have a size of 0.05 mm to 0.09 mm.

The core beads may have a size of 0.4 mm.

The core beads and the small beads can be combined by heat fusion.

The photoluminescent aggregate pieces are irregular and may be coated with a luminous material.

The coating may include a silane-based curing agent.

According to another aspect of the present invention, a lane construction method for hardening at room temperature having excellent reflectance during rain includes providing a circular core beads for rain; Placing small beads, and attaching the small beads to the core beads so that the outer peripheral surface of the core beads is filled; Preparing a photoluminescent aggregate piece supporting the core beads by mixing with the core beads to which the small beads are attached; Applying a paint for forming a lane to the lane; And spraying the core beads to which the small beads are attached and the photoluminescent aggregate pieces together on the paint of the lane.

1 is a cross-sectional view of a wear-resistant room temperature curing lane structure having excellent reflectance at night in rain according to an embodiment of the present invention.

Referring to FIG. 1, a lane structure for hardening at room temperature that has excellent reflectance at night in rain according to an embodiment of the present invention, a core bead 100 and a small bead 110 that is attached while filling the outer peripheral surface of the core bead 100 , The small beads 110 is mixed with the core beads 100, the phosphorescent aggregate pieces 120 supporting the core beads 100, and the small beads 110 attached to the core beads 100 and the phosphorescent aggregate pieces 120 includes a paint 130 is sprayed.

One embodiment of the present invention, while being able to sufficiently exhibit the reflection performance in the water by the core beads 100 and the small beads 110 of the outer circumferential surface at the time of rain at night, the small beads 110 together with the core beads 100 ) Can be prevented from being separated or worn on the reflector for the retroreflection of the vehicle light from the impact of the vehicle wheel by being contacted and restrained by the photoluminescent aggregate piece 120, and is excellent in coloring and construction on the road.

The core beads 100 are beads made of rainy ceramic or glass, and have a size of 0.4 mm. In the case of the glass beads for the rain, the core beads 100 have a refractive index of 1.5 or more. In the rainy weather, the glass grains are submerged, so the water has a refractive index of 1.33, and the total refractive index is 1.8 or more.

A small bead 110 is attached to the outer circumferential surface of the core bead 100. The small beads 110 may be used for reflection of signs, have a dry refractive index of 1.54, and have a size of 0.05 mm to 0.09 mm.

Accordingly, when the small beads 110 are attached to the outer circumferential surface of the core beads 100 and are immersed in water, a refractive index of about 3.54 is formed.

The core beads 100 and the small beads 110 may be combined by heat fusion. If the core bead 100 is rolled on the small bead 110 while the core bead 100 is heated, the small bead 110 may be attached to the core bead 100.

The combination object of the core bead 100 and the small bead 110 is a structure in which the small bead 110 is not well separated from the core bead 100, and then is sprayed on the paint 130 to the core bead 100 Since the contact area with respect to the paint 130 is larger than itself, it is difficult to detach from the paint 130.

The core beads 100 with the small beads 110 are sprayed together with the phosphorescent aggregate pieces 120 on the paint 130 applied to the lane, thereby coating the paint 130 by the phosphorescent aggregate pieces 120 with many projections in an irregular shape. ).

The fixing of the core beads 100 by the photoluminescent aggregate pieces 120 is that the core beads 100 of a round shape are formed by irregularly shaped aggregate pieces, and the binding force is large, from the paint 130 of the core beads 100 It is difficult to escape. The photoluminescent aggregate piece 120 is a hard aggregate having a Mohs hardness of 5 to 7.

Meanwhile, the photoluminescent aggregate piece 120 is indefinite and a luminous material 121 may be applied. The photoluminescent aggregate piece 120 is coated with a photoluminescent material that absorbs light energy during the day, so that it can be flashed by light during rainy nights.

Phosphorescent aggregate pieces 120 are 0.1 mm to 2 mm, which are larger than rainy glass grains, and are disposed at a ratio of 0.5 to 1:1 with core beads 100 sprayed together.

The photoluminescent material for the photoluminescent aggregate piece 120 may be coated in advance, and the photoluminescent powder, which is the photoluminescent material, may be mixed with the resin coating and applied while impregnating the photoluminescent aggregate piece 120. SrAL ₂ O ₄ may be used as the photoluminescent pigment.

Meanwhile, the coating material 130 may include a silane-based curing agent 140.

Since the silane-based curing agent 140 is mixed with the coating 130, the core beads 100 to which the small beads 110 are adhered and the photoluminescent aggregate pieces 120 can be easily seated on the coating 130 while being sprayed. The silane-based curing agent 140 is mixed with the paint 130 in a few tens of percent, and is a material capable of enhancing the grip of the core beads 100 and the photoluminescent aggregate pieces 120 in the paint 130.

Referring to Figures 1 and 2, the lane construction method for abrasion resistance at room temperature curing excellent at night rain, according to an embodiment of the present invention, the step of providing a circular rain core beads 100, small beads 110 Placing them and attaching the small beads 110 to the core beads 100 so that the outer circumferential surface of the core beads 100 is filled, the core beads 100 mixed with the core beads 100 to which the small beads 110 are attached The step of providing a phosphorescent aggregate piece 120 for supporting, the step of applying the paint 130 for forming a lane to the lane, and the core beads (110) is attached to the small beads 110 on the lane of the paint 130 100) and the step of spraying the photoluminescent aggregate pieces 120 together.

As described above, the coating 130 may be mixed with the core beads 100 to be sprayed and the salan-based curing agent 140 for easy seating of the phosphorescent aggregate pieces 120. In addition, the core beads 100 and the small beads 110 are heat-sealed and coupled to each other, making it difficult to separate from each other. Pigment may be applied to the photoluminescent aggregate piece 120 as a luminous material 121 that can accumulate light and can be exhibited by the light.

According to the present embodiment, the small beads 110 are circumscribed by air pressure thereon with a slight parallax while spraying and coating the main material of the paint 130 and the curing agent 140 on the lane using two paint pumps. The core beads (100) and photoluminescent aggregate pieces (120) adhered to are sprayed to settle. Substantially, the paint 130 is sprayed first, and the core beads 100 are sprayed directly thereon, and then the photoluminescent aggregate piece 120 is sprayed immediately thereafter.

The present invention as described above can be applied not only at room temperature curing type lane painting, but also at the time of construction of the fusion-type paint 130, and when applied to a fusion-type coating with weak abrasion resistance, gives an effect of slowing the progress of wear and friction of the painting. By improving the resistance BPN, it is possible to provide prevention of a slip accident that may occur in a wide area of a painted surface such as a vehicle guide line or a pedestrian crossing.
