Retroreflection Type Slipping-proof Pavement and Method for Consructing the Same}

The present invention relates to a non-slip packaging material having a retroreflective function and a method of constructing the non-slip packaging material, and more particularly, includes a retroreflective bead for reflecting light back to a light source on a surface, thereby making it visible at night. It is high, and particularly relates to a retroreflective anti-slip packaging material and its construction method that can be easily recognized by the user by exhibiting excellent retroreflective performance even in the presence of water on the packaging due to rain or the like.

Anti-slip pavement is a pavement surface in places where the slip resistance of the road surface is low, in areas where the road planes and terminators are poor, and in other intersections where the slip resistance must be improved, road ramps, parking entrances, child protection areas, and sections in front of the stop line. It is a facility that is installed on the floor for the purpose of improving the visibility and at the same time shortening the braking distance of cars or bicycles by increasing the skid resistance.

In general, a method of constructing a non-slip packing material is to attach a masking tape to the outside of the construction part where the non-slip packing material is intended to be applied, and to apply a synthetic resin as a binder, and then to a general aggregate having high abrasion resistance and coefficient of friction of 3 to 5 mm (steelmaking) Slag or silica sand), and the synthetic resin and aggregate are fixed to the road surface by pressing through a roller for compaction, thereby completing a non-slip road surface.

However, since the conventional non-slip packaging material is constructed in consideration of simply increasing the frictional force, there is a problem that a person is not visually identified at night and does not properly perform dk protection or warning function, especially due to rainy weather. In the wet state, there was a problem that visibility was greatly reduced.

The present invention is to solve the above problems, the object of the present invention is excellent in retroreflective performance can be easily recognized by the user, especially when the surface of the packaging material wet due to rainy weather excellent reflex reflection The present invention provides a retroreflective anti-skid packaging material and its construction method that can provide improved performance by providing better performance.

According to one category of the present invention for achieving the above object, the base layer cured by uniformly compacted the ground upper surface; An anti-slip layer formed by applying a mixture of a monomer of MMA (methyl metha acrylate) and an MMA resin, a curing agent, and an aggregate to an upper surface of the base layer; There is provided a retroreflective anti-slip packaging material comprising retroreflective beads disposed on the non-slip layer to reflect light.

Here, the reflex reflection beads are a ball-shaped core (core), a plurality of shell beads (shell beads) having a fine refractive index of 1.9 or more adhered to the outer surface of the core body, and the core and shell beads It is configured to include a protective coating layer is applied to the outside of the composite made of filling the pores due to the non-adhesive spacing between the shell beads.

According to another category of the invention, the step of curing the base layer on the upper surface of the ground; Forming a non-slip layer by applying a mixture of a methyl metha acrylate (MMA) resin, a monomer of MMA resin, a curing agent, and an aggregate to an upper surface of the base layer; Provided is a method of constructing a retroreflective anti-slip packaging material comprising the step of spraying the antireflective beads at a predetermined pressure and laying them on the non-slip layer before the non-slip layer is cured.

According to the present invention, the retroreflective beads made of the core and shell beads and the protective coating layer are exposed to the outside on the surface of the non-slip layer, the retroreflective beads are formed on the shell beads formed on the surface of the core body This provides excellent retroreflective performance in wet conditions as well as in dry conditions. Therefore, visibility is improved even at night or in a state where the non-slip packing material is wet with water, so that the user can easily recognize the packing material and there is an advantage of improving safety.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the retroreflective anti-skid packaging material and its construction method according to the present invention.

Figure 1 shows the configuration of the retroreflective anti-slip packaging material according to the present invention, the retro-reflective anti-slip packaging material of the present invention is the base layer 10 and hardened by uniformly compacting the upper surface of the ground, the base layer The primer 20 applied to the upper surface of the (10), the anti-slip layer 30 is formed by applying the MMA resin mixture on the upper surface of the primer 20, and the anti-slip layer 30 is installed to reflect light Retroreflective beads 50 and glass beads 60.

The base layer 10 may be made of ascone, pitcher cone, concrete, and the like. In addition, the primer 20 is used in combination with a diluent, wherein the diluent to be blended is preferably 30% or less by the weight ratio of the primer 20. The primer 20 may be omitted when the base layer 10 is asphalt.

The anti-slip layer 30 is formed to a thickness of 1 ~ 2㎜, irregularities are formed on the surface to provide a great frictional force and to provide the driver with the effect of preventing overspeed by feeling fine vibration, recursion laid on the surface Reflective beads 50 and glass beads 60 provide high visibility. Here, the anti-slip layer 30 is a conventional aggregate (steel slag) having a high coefficient of friction and coefficient of friction, monomer, hardener and abrasion resistance of MMA (methyl metha acrylate) resin and MMA resin having excellent adhesion to the base layer 10 Or silica sand). The monomer mixed in the anti-slip layer 30 lowers the viscosity of the MMA resin so that the retroreflective bead 50 and the glass bead 60 are well inserted into the anti-slip layer 30 to be fixed. The MMA resin and the monomer to be mixed in the anti-slip layer 30 is preferably in a ratio of 40: 1.

And, the curing agent mixed in the MMA resin mixture to form the anti-slip layer 30 is preferably mixed with 100 ~ 200g in the summer, 200 ~ 500g in the winter season with respect to 25kg MMA resin.

The retroreflective bead 50 and the glass bead 60 have a predetermined pressure (eg, 4 to 10) by spraying equipment such as airless before the non-slip layer 30 is cured after the non-slip layer 30 is applied. kgf / cm 2). The retroreflective beads 50 and glass beads 60 should be partially exposed to the outside without being completely immersed in the anti-slip layer 30 in order to reflect light, and the retroreflective beads 50 and glass beads 60 may be exposed. If too much of the non-slip layer 30 is exposed to the outside is small reflecting performance is reduced, on the contrary, too shallow is embedded in the reflection performance is improved but the anti-slip layer 30 can easily fall off and the durability can be reduced. Therefore, it is preferable that about half of the retroreflective beads 50 and the glass beads 60 are immersed in the anti-slip layer 30 and the other half are exposed to the outside.

The glass bead 60 is made of a ball-shaped glass or resin having a refractive index of about 1.5, and may be one having a particle diameter of about 300 to 800 μm, but is not limited thereto. The glass beads 60 and the retroreflective beads 50 are preferably mixed in a weight ratio of about 7: 3, but are not limited thereto. Only the retroreflective beads 50 may be used without using the glass beads 60 at all. It can also be used alone.

In addition, the retroreflective bead 50 has a particle size of about 800 ~ 1200㎛, even if the non-slip packaging material is wet in water due to rain, such as dry conditions, very excellent retroreflective performance, friction or It is not easily separated from the anti-slip layer 30 by the impact is made of a durable structure. As shown in FIG. 2, the recursive bead 50 in the present invention has a ball-shaped core body 51 and a fine ball-shaped shell bead fixed to an outer surface of the core body 51. (shell beads) 52 and the protective coating layer 53 is applied to the outside of the composite consisting of the core body 51 and the shell bead 52 to fill the pores due to the non-adhesive separation between the shell beads It is composed.

The core body 51 may have a particle diameter of 600 to 1000 μm, and various inorganic balls, such as soda ash glass, alumina ball, zirconia ball, silicon carbide ball, and the like, may be used.

In addition, the shell beads 52 are fine balls having a particle diameter of 40 to 100 μm, a refractive index of 1.9 or more, and more preferably, a refractive index of about 1.93, and are fixed to the outer surface of the core body 51 by an adhesive and recursively. Functions to improve reflectivity. In other words, since the shell bead 52 has a refractive index of 1.9 or more, which is higher than the refractive index of the glass beads 60, the anti-slip packaging material may be wetted with water (refractive index 1.33) so that a water film is formed. The difference in refractive index between the water increases and the reflectance increases (1.9 / 1.33). If the refractive index of the shell bead 52 is higher than 1.93, since the reflection reflectance of light is formed inside the shell bead 52, there is a disadvantage that the retroreflectivity in the air is decreased, so the refractive index of the shell bead 52 is 1.90 to 1.93. Is preferably.

The protective coating layer 53 is applied to the outside of the composite consisting of the shell beads 52 and the core body 51 and then hardened by heating to be generated between the shell beads 52 and the core body 51. Filling the pores increases the bonding area and prevents the shell beads 52 from being detached from the core body 51. The protective coating layer 53 is a hybrid type product having a light transmittance of 90% or more and is a hybrid coating liquid of an organic-inorganic hybrid or a sol-gel hybrid type. Is made using.

The retroreflective beads 50 having the structure described above were usually 280-320 mcd / m 2 / lx and the rainy weather 180-250 mcd / m 2 / lx was very good.

In addition, the retroreflective bead 50 may be manufactured in the same color as the color of the anti-slip layer 30, thereby providing an effect of beautiful appearance.

Next, a method of constructing an anti-slip packaging material of the above-described embodiment will be described with reference to FIG. 3.

First, curing the base layer 10 on the upper surface of the ground (step S1), attach a masking tape (not shown) on the upper surface of the cured base layer 10 (step S2) and then apply the primer 20 (Step S3). At this time, the upper surface of the base layer 10 is preferably maintained in a clean state in which dust, moisture, dirt, and the like. When the base layer 10 is asphalt, the primer 20 may not be applied separately.

Next, the mixture which mixed the monomer, hardening | curing agent, and aggregate of MMA resin and MMA resin was put into the stirrer, and stirred, and this mixture is apply | coated on the upper surface of the said primer 20 (step S4). At this time, before the non-slip layer 30 is cured, the retroreflective beads 50 are sprayed and laid on the non-slip layer 30, and the glass beads 60 are sprayed and laid (step S5). The pressure at the time of spraying the retroreflective beads 50 is preferably slightly larger than the pressure at the time of spraying the glass beads 60.

As described above, the reason for laying the retroreflective beads 50 in the non-slip layer 30 first and then laying the glass beads 60 later is that the glass beads 60 have a high specific gravity and thus spray the glass beads 60 first. Since the glass beads 60 have a high possibility of being completely immersed in the non-slip layer 30 which has not yet been cured, a recursive bead 50 having a relatively small specific gravity is installed first, and the anti-slip layer 30 is hardened. If the glass bead 60 is laid after some progress, not only the reflex reflection beads 50 but also the glass beads 60 may be exposed to the outside to provide an excellent reflection function.

Of course, in the above-described embodiment, the retroreflective bead 50 is installed on the anti-slip layer 30 and then the glass bead 60 is installed. Alternatively, the retroreflective bead 50 and the glass bead 60 may be provided as necessary. ) May be installed together.

Finally, the masking tape is removed to finish the construction (step S6).

On the other hand, the above-described retroreflective anti-slip packaging material sprays the retro-reflective beads 60 to the mixture of the MMA resin and the monomer, the curing agent, and the aggregate of the MMA resin to form a non-slip layer 30, Figure 4 and Figure As shown in another embodiment of FIG. 5, without adding a monomer of the MMA resin to dilute the MMA resin, a mixture of the MMA resin, the curing agent, and the aggregate is applied onto the primer 20 to prevent the anti-slip base layer 30a. ), And then, the water-soluble emulsion resin layer 30b is applied on the non-slip base layer 30a at regular intervals or at a designated specific position, and the retroreflective beads (30) are applied to the water-soluble emulsion resin layer 30b. 50 and the glass bead 60 may be sprayed to form an anti-slip layer 30.

The water-soluble emulsion resin layer 30b may be made of the same color as the color of the MMA resin, but may use a different color from the MMA resin to display a specific line or pattern.

The embodiments of the above-described retroreflective anti-slip packaging material and its construction method are presented for illustrative purposes only to help understanding of the present invention, and the present invention is not limited thereto, and those skilled in the art to which this technology belongs. If various modifications and implementations are possible within the scope of the appended claims.
