Description

Method of manufacturing eco-friendly anti-slip packaging materials

The present invention relates to a method for manufacturing an eco-friendly non-slip pavement material, and more particularly, manufacturing an eco-friendly non-slip paving material that uses methyl methacrylate resin as a binder to have excellent adhesion and abrasion resistance to the road surface and to express various colors. it's about how

In general, for safe vehicle operation, the driver of the road has a sharp curve area, a downhill slope, an area requiring acceleration, a crossroad, a crosswalk, a roundabout, etc. It is necessary to maintain an appropriate safe speed according to the conditions of the road that change frequently, such as icing, hydroplaning, and changes in road characteristics.

That is, if the vehicle exceeds the appropriate safe speed while driving on the road, the friction coefficient between the vehicle's tire and the road surface decreases in proportion to the excess amount, and control over the vehicle is lost and the possibility of an accident increases. .

Therefore, in places where the slip resistance of the road surface is low, or where the flatness and longitudinal alignment of the road are poor, the anti-slip pavement is used to prevent the vehicle from slipping by increasing the slip resistance of the road surface and creating a high friction force between the vehicle tire and the road surface. is being done

Such anti-slip pavement is not only made on roads, but in recent years, non-slip pavement is applied in various places such as roads, parking lots, parks, etc. where people walk, such as school commuting roads and crosswalks, in order to increase traffic safety for pedestrians.

On the other hand, the conventional anti-slip pavement is constructed on-site by mixing an anti-slip material such as a lightweight aggregate with a thermosetting resin such as an epoxy or urethane-based resin.

After removing foreign substances or dust on the road surface where the non-slip pavement is to be made, tap it to fit the area where the non-slip pavement is to be formed. As an anti-slip material with excellent abrasion resistance, a lightweight aggregate with a Mohs (MOHS) hardness of 8.0 or more and a particle diameter of about 5 mm, or by spraying steelmaking slag, silica (SiO2), waste glass, etc., and using a heavy roller If it is pressed and left for 4 to 5 hours in a state where the thickness is uniformly formed to a height of about 3 to 5 mm, the thermosetting resin permeates between the anti-skid materials and hardens, thereby preventing slippage by allowing frictional force to act between the vehicle tires. making it possible

However, the conventional binder used for non-slip packaging mainly uses epoxy or urethane-based resins, so it not only takes a long time to dry and cure after construction, but also has the disadvantage of being inconvenient to construct as a two-component type, and the use of organic solvents As a result, it has the disadvantage that it is not environmentally friendly.

Even after the anti-slip pavement is made, due to the problem of deterioration of physical properties such as hardening and adhesiveness of the binder, the adhesion and bonding strength of the binder is lowered due to the load and impact of a large truck, and the road surface is cracked and the anti-slip effect is rapidly reduced.

In addition, although Korea has four distinct seasons, the winter temperature is very low depending on the region, resulting in considerable damage.

Therefore, most drivers drive safely at an appropriate safe speed because the vehicle can easily slide on a road where there is a lot of snow in winter or where there is ice after a lot of snow. In the case of not falling to the ice, there are cases where we neglect to pay attention to freezing.

Black ice refers to a phenomenon in which a thin film of ice is formed on the road surface as if it were coated when drizzle or drizzle falls on the road surface below 0℃ or when the surface temperature of an already wet road falls below the freezing point. It mainly occurs in shady, low-temperature places such as shady roads and mountain corners.

This black ice is made of a thin layer of ice and the color of the asphalt is projected as it is, so it is very difficult for the driver of a running vehicle to identify with the naked eye. becomes this

Accordingly, in recent years, various methods have been proposed to prevent traffic accidents caused by black ice.

As an example, when black ice is expected to occur, there is a forecasting system that guides it through a road electronic board, but there is a disadvantage in that the accuracy of the forecasting system is still greatly reduced.

As another example, there is an automatic salt water spray system that sprays salt water for snow removal installed at the entrance/exit of a hill, bridge, or tunnel where black ice is mainly generated habitually. It has a disadvantage that it is very difficult to maintain and manage the performance.

As another example, a method of laying a heating wire under the road at the entrance/exit of a hill, bridge, or tunnel, where black ice is mainly generated habitually, has been proposed. There is also a disadvantage in that maintenance and management costs increase due to electricity bills for

As another example, there is grooving that prevents slippage by digging safety grooves at regular intervals in the road surface of hill roads, bridges, or tunnel entrances and exits where black ice is mainly generated habitually to increase friction with vehicle tires. , after cutting the safety groove, the road section is exposed as it is, and the durability of the road decreases as rainwater penetrates. There is also the disadvantage of generating a lot of noise and vibration due to the friction of

1 is a block diagram according to a first embodiment of the method for manufacturing an eco-friendly non-slip packaging material of the present invention.

It will be described with reference to FIG. 1 .

The eco-friendly non-slip pavement manufacturing method of the present invention includes a binder manufacturing step (S10), a mixing step (S20), and a stirring step (S30) so as to have excellent adhesion to the road surface and abrasion resistance, and to enable expression of various colors.

The binder manufacturing step (S10) includes a first stirring step (S101) and a second stirring step (S102) to prepare a binder.

In the first stirring step (S101), 25 to 35% by weight of the binding resin and 10 to 15% by weight of the color pigment are added to a mixing stirrer and stirred for 10 to 20 minutes.

In the second stirring step (S102), 50 to 60 wt% of calcium carbonate (CaCo3) is added to a mixing stirrer after the first stirring step (S101) and stirred for 15 to 25 minutes.

The calcium carbonate (CaCo3) is an ionic compound composed of calcium ions (Ca2+) and carbonate ions (CO32-), and exists in a crystalline form as a main component of rocks. Calcite and aragonite are mostly occupy

It is the main component of pearls and shells, and egg shells are also mostly made of calcium carbonate, so they are cheap and eco-friendly, so they are used in a wide variety of industrial fields.

It is preferable that the stirring temperature at which the stirring is performed in the first stirring step (S101) and the second stirring step (S102) is 10 to 70°C.

That is, if the stirring temperature in the first stirring step (S101) and the second stirring step (S102) is lower than 10 ℃, the raw material of the binder is not sufficiently mixed and stirred, and when the stirring temperature is higher than 70 ℃, the There is a high possibility of damage and change of properties.

That is, the binding resin is characterized in that it further comprises 10 to 20 parts by weight of the EPS solution and 10 to 20 parts by weight of the crosslinking agent with respect to 100 parts by weight of the methyl methacrylate resin.

Polystyrene molecules in the EPS (Expanded Polystyrene) solution are not directly involved in the polymerization reaction, but copolymerize in the presence of a methyl methacrylate resin and a crosslinking agent to enhance the strength when curing the binder.

It is preferable to use trimethylopropane trimethacrylate as the crosslinking agent.

Trimethylopropane trimethacrylate (TMPTMA) crosslinking agent is a trifunctional monomer with good reactivity. It provides rigidity to the matrix by forming a polymer of a three-dimensional network structure through a copolymerization reaction with methyl methacrylate resin, thereby increasing heat resistance, strength, and rigidity. will increase

On the other hand, when the mixing amount of the crosslinking agent is less than 10 parts by weight, the effect of increasing heat resistance, strength, and rigidity is significantly reduced. will appear

In an embodiment, the binding resin may further include 10 to 20 parts by weight of a retroreflective agent based on 100 parts by weight of the methyl methacrylate resin.

The retroreflective agent has a refractive index of 1.5 or more, has a particle diameter of 300 to 1,000㎛, has excellent retroreflectivity, and has strong durability and strength so as not to be easily removed from the non-slip packaging material by friction or impact, a retroreflective type It is preferable to use any one or more selected from the group consisting of beads and glass beads.

By further including a retroreflective agent in the binder, the retroreflection performance is improved, making it easier to identify pedestrians and drivers even at night. Thus, it is possible to provide more improved visibility.

In one embodiment, the binding resin may further include 5 to 10 parts by weight of a curing agent based on 100 parts by weight of the methyl methacrylate resin.

The curing agent is preferably benzoyl peroxide.

Benzoyl peroxide is a curing agent that is easily soluble in organic solvents such as ether, and is mainly used as a polymerization initiator to initiate radical polymerization of vinyl units by generating phenyl radicals and benzoate radicals by thermal decomposition in the solvent.

The amount of time required for curing of the binder resin is shortened by mixing more curing agent with the binder resin. If the amount of the curing agent is too small, partial curing failure occurs, and if the amount of the curing agent is too large, curing imbalance may occur. It is preferable to use 5 to 10 parts by weight based on 100 parts by weight of the methyl methacrylate resin.

In one embodiment, the binding resin may further include 3 to 5 parts by weight of a polymerization accelerator based on 100 parts by weight of the methyl methacrylate resin.

The polymerization accelerator serves to help the generation of synthetic radicals that induce a chain polymerization of methyl methacrylate resin or a copolymerization reaction between methyl methacrylate resin and a crosslinking agent. It is preferable to use a DMA (dimethyl aniline) polymerization accelerator. .

If the amount of the polymerization accelerator is too small, the curing time is too late, so the working time is delayed, and the complete curing of the surface is delayed, which increases the possibility of contamination by contaminants. Because it may cause shrinkage and dichroic change, the amount of the polymerization accelerator used is preferably 3 to 5 parts by weight based on 100 parts by weight of the methyl methacrylate resin.

In one embodiment, the bonding resin may further include 1 to 3 parts by weight of a coupling agent based on 100 parts by weight of the methyl methacrylate resin.

The coupling agent serves to enhance the interfacial adhesion between the methyl methacrylate resin, which is the main raw material of the binding resin, and the non-slip material, which is an inorganic material. bonding is made.

As the coupling agent, γ-methacryloxypropyltrimethoxy silane is preferably used as the silane coupling agent.

In one embodiment, the binding resin may further include 1 to 2 parts by weight of a curing accelerator based on 100 parts by weight of the methyl methacrylate resin.

The curing accelerator serves to shorten the curing time of the bonding resin by inducing a room temperature reaction of the curing agent, and amine-based compounds such as dimethyl aniline, diethyl aniline, diethanol aniline, dimethyl-p-toluidine, diisopropoxy- It is preferably at least one selected from the group consisting of p-toluidine and N,N-bis-(2-hydroxyethyl)-p-toluidine.

Even if a certain amount or more of the curing accelerator is used, the curing time does not continue to be shortened in proportion to the amount used, and if used excessively, it causes coloration. It is preferable to use 2 to 2 parts by weight.

In one embodiment, the binding resin may further include 1 to 2 parts by weight of a stabilizer based on 100 parts by weight of the methyl methacrylate resin.

The stabilizer includes any one or more selected from the group consisting of ultraviolet absorbers, antioxidants, deterioration inhibitors, and gelation inhibitors.

The ultraviolet absorber is for preventing the anti-slip packaging material manufactured by the present invention from aging by ultraviolet rays, and is preferably at least one selected from the group consisting of phosphorus-based, phenol-based, sulfur-based, and thiazole-based absorbents.

In the mixing step (S20), the binder and the anti-slip material are mixed in a ratio of 1.5:1.

In one embodiment, the anti-slip material is preferably at least one selected from the group consisting of lightweight aggregate having a Mohs hardness of 8.0 or more and a particle diameter of 3 to 5 mm, steel slag, silica, and waste glass as the main material.

In one embodiment, the anti-slip material, with respect to 100 parts by weight of the main material, may further include 10 to 20 parts by weight of the anti-slip auxiliary material.

As the anti-slip auxiliary material, it is preferable to use a mixture of silica sand having a particle diameter of 1 to 3 mm, bauxite, and shell in a weight ratio of 1:1:1.

The silica sand refers to sand whose main component is silicon dioxide (SiO₂), has translucency, fire resistance, high hardness, and is used as an oxidizing agent in deoxidation and desulfurization.

If the proportion of silica sand among the anti-skid auxiliary materials is too small, economic efficiency is lowered. It is desirable to keep the ratio of silica sand constant because it can easily fall off when friction or impact occurs.

In addition, if the particle diameter of the non-slip auxiliary material is too small, since irregularities due to the non-slip auxiliary material hardly occur after the construction of the non-slip packaging material is completed, an additional slip resistance value cannot be obtained by the non-slip auxiliary material, and on the contrary, the particle diameter is If too large, the surface protrusion after completion of the construction of the anti-slip packaging material is excessive, and there is a disadvantage that the slip resistance value of the anti-slip material is rather lowered. Therefore, the particle diameter of the anti-slip auxiliary material is preferably 1 to 3 mm.

In the stirring step (S30), the binder and the anti-slip material are stirred for 5 to 10 minutes.

If the stirring time of the binder and the anti-slip material is too short, the binder and the anti-slip material are not sufficiently mixed and stirred, and the bonding force between the binder and the anti-slip material is lowered. The stirring time is preferably 5 to 10 minutes.

The non-slip packaging material manufactured by the method for manufacturing the eco-friendly non-slip packaging material of the present invention constituted as described above uses methyl methacrylate resin as a binder to provide adhesion to the road surface, abrasion resistance and transparency, durability, heat resistance, chemical resistance, and UV safety. In addition to this excellent colorability, it is easy to express various colors because it is easy to express various colors in sharp curves, downhill slopes, areas requiring acceleration, intersections, crosswalks and roundabouts, as well as school commuting roads and roads where people walk. , parking lot, park, etc., it has the effect of being usable in various places.

2 is a block diagram according to a second embodiment of the method for manufacturing an eco-friendly non-slip packaging material of the present invention.

Although it will be described with reference to FIG. 2 , a detailed description of components having the same reference numerals and components overlapping those of the above-described embodiment will be omitted.

In one embodiment, the binder manufacturing step (S10) may further include a third stirring step (S103).

In the third stirring step (S103), after the second stirring step (S102), 5 to 10% by weight of the thermosensitive resin is added to the mixing stirrer and stirred for 5 to 10 minutes.

In one embodiment, the thermosensitive resin,

It is characterized in that it contains 80 to 90% by weight of methyl methacrylate resin, and 10 to 20% by weight of thermosensitive microcapsules.

If the temperature-sensitive microcapsule is less than 10% by weight, the amount is too small to identify a color change with the naked eye, and when it exceeds 20% by weight, the color change does not occur any more, so the meaning of increasing the content is no longer there will be no

The temperature-sensitive microcapsule is a microcapsule of a pigment that changes color depending on temperature, and is preferably a spherical polymer containing polypropylene or polyethylene with high dispersion, but is not limited thereto. The temperature-sensitive microcapsule is a powder, It may be in the form of a slurry or wax.

In addition, it is preferable that the temperature-sensitive microcapsule changes color to a set color when the ambient temperature falls below 0°C.

As an example, the temperature-sensitive microcapsule has a specific color when the ambient temperature is 1°C or higher, and loses color when the ambient temperature falls below 0°C and becomes transparent, or floats the first color when the ambient temperature is 1°C or higher Then, when the ambient temperature drops below 0°C, it changes to the second color, or when the ambient temperature is above 1°C, it is transparent, and when the ambient temperature falls below 0°C, it can have a specific color.

On the other hand, it is preferable that the stirring temperature at which the stirring is made in the third stirring step (S103) is 10 to 70 ℃.

That is, if the stirring temperature is too low in the third stirring step (S103), the thermosensitive resin is not sufficiently mixed and stirred with the mixture that has passed the second stirring step (S102), and if the stirring temperature is too high, the thermosensitive resin is formed Since the possibility of decomposition of the thermosensitive microcapsule increases, the stirring temperature in the third stirring step (S103) is preferably 10 to 70°C.

The non-slip packaging material manufactured by the method for manufacturing an eco-friendly non-slip packaging material of the present invention configured as described above has a unique color combined with the color of the coloring pigment included in the binder or the color of the coloring pigment when the road surface temperature is 1 ° C or higher. A, when the road surface temperature drops below 0℃, the color is changed by the thermosensitive resin.

Therefore, if the non-slip pavement material containing thermal resin is completely or partially paved on a road where black ice occurs frequently, the color of the road changes when the surface temperature of the road drops below 0℃ and becomes a condition for black ice to occur. As a driver on the road can immediately recognize the risk of black ice by changing the color of the road surface and take measures such as deceleration, the risk of a traffic accident caused by black ice can be reduced.

As mentioned above, although the embodiment of the present invention has been described in detail, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also provided. is within the scope of the right.
