Description

Thermal paving material composition and road paving method using pattern thereon {road paving material composition for heat shielding and road packing method using same}

The present invention relates to a heat shielding pavement material and a road pavement construction method having a pattern formed using the same, and more particularly, including a surface-modified volcanic ash, the pavement composition having excellent heat shielding effect and the pavement composition asphalt or concrete road It relates to a road pavement construction method that can form a pattern on the road surface when it is newly installed or coated on the top.

Recently, due to the rapid industrialization and urbanization, the density of the population and the increase of residential, commercial space, and public facilities are decreasing the area of green space. In particular, due to the increase in artificial heat and various air pollutants in urban areas of the large cities, the heat island phenomenon in which the temperature in the city rises locally occurs frequently due to the unstable circulation of solar energy in the natural state. have.

One of the many causes of this heat island phenomenon is the urban surface is paved with artificial structures. Infrared rays, which occupy half of the sun's rays, are absorbed by the surface of roads, roofs, or exterior walls to generate thermal energy, which is transferred to the interior, increasing the temperature on the road or inside the building. Particularly, asphalt or concrete roads have daytime heat loss and rapid heat transfer characteristics for solar near-infrared and atmospheric heat, and the surface temperature of the pavement increases rapidly. It causes an increase. Therefore, it is necessary to minimize the road surface or room temperature change by efficiently blocking the heat generated by the infrared absorption, and the research on heat shield packaging is in progress.

Thermal insulation paving is a paving method that lowers the surface temperature of the pavement by reducing the solar absorption rate of the package by applying special paints or resins with excellent reflecting properties to the pavement surface, thereby highly reflecting near-infrared rays, which occupy half of the solar radiation energy. In this regard, Republic of Korea Patent No. 10-0741147 (Road heat shielding paint), Republic of Korea Patent No. 10-1255147 (heat shielding packaging composition and paving method using the same), Republic of Korea Patent Publication No. 10-2011-0006772 (Paint composition) discloses a technique related to a heat shield packaging composition.

However, the existing heat-shielding packaging composition is limited in color because the heat shielding effect is mainly obtained in order to maximize the reflection by the color, and the heat shielding effect is insufficient because such a technique is expected only the reflection effect of sunlight. In Korea, a composition in which hollow particles known to have excellent heat shielding properties are mixed with a coating material is used. However, the paint simply mixed with the hollow particles has a problem that the heat shielding effect is lowered due to the penetration of foreign matter and moisture into the hollow particles floating on the surface due to the difference in specific gravity with time. In addition, another method of the related art has been disclosed to manufacture a heat-shielding packaging composition using a mica that is a reflective heat shield, but the method may reduce the heat shielding effect due to a difference in thermal conductivity when the size of the mica is large. The sedimentation phenomenon occurs, causing a problem that the deviation of the heat shielding effect becomes large. In addition, the Republic of Korea Patent Publication No. 10-2014-0045035 (shielding and insulating paint containing additives) is disclosed a coating composition comprising a volcanic ash of a porous, but the volcanic ash is not good dispersibility, agglomeration occurs, the composition Also did not have sufficient thermal insulation performance.

In order to solve this problem, the present inventors have developed a pavement composition having a good thermal insulation effect by improving the dispersibility of volcanic ash and a road pavement construction method capable of forming a pattern for improving visibility.

Hereinafter, the present invention will be described in detail.

In order to achieve the above object, the present invention (step 1) the step of laying the package on the construction surface;

(Step 2) applying a fiber sheet on the package;

(3) applying a packaging material composition comprising a surface-modified volcanic ash on the fiber sheet; And

(4) forming a pattern on the surface of the pavement composition; provides a road paving construction method using a pavement composition for heat shielding.

At this time, the package in the first step may be asphalt or concrete.

In the step of applying the fiber sheet on the package of the second step, if the package is concrete, the operation of applying the primer to the upper surface of the concrete before applying the fiber sheet to improve the adhesion may be performed first.

In addition, the fiber sheet in the second step may be a fiber sheet manufactured by a glass fiber sheet or a stitch bonding method.

In the third step, the packaging material composition may include an acrylic resin, a heat shield pigment, a hollow bead, a surface-modified volcanic ash, a crosslinking agent, an inorganic filler, and a curing agent.

More preferably, the packaging material composition is preferably a two-component type in which an acrylic resin, a heat shield pigment, a hollow bead, a surface-modified volcanic ash, a crosslinking agent, and an inorganic filler and a curing agent are mixed.

The packaging composition has a pot life (working) time of 15 to 60 minutes at room temperature (20 ± 5 ℃) through the configuration of the two-component, thereby causing problems such as equipment damage as the heat shielding material is cured during the coating operation The workability can be secured by eliminating it.

In this case, the acrylic resin is methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethyl butyl acrylate, 2-ethylhexyl (meth) acrylate, hexyl acrylate, heptyl acrylate, octyl acrylate, n-pentyl acryl Rate, vinyl acrylate, lauryl acrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, 2-ethyl butyl methacrylate, 2-ethylhexyl methacrylate, lauryl methacrylate, methyl It may be at least one selected from the group consisting of methacrylate, ethyl acrylate and polymethyl methacrylate.

The heat shield pigment may be at least one selected from the group consisting of titanium oxide, tin oxide, zinc oxide, magnesium oxide, zirconium oxide, cerium oxide, and antimony oxide, preferably titanium oxide, more preferably titanium dioxide Can be. The heat shield pigment is preferably included in 1 to 10 parts by weight based on 100 parts by weight of acrylic resin. When the content of the heat shield pigment is less than 1 part by weight based on 100 parts by weight of the acrylic resin, the solar reflectance of the packaging material composition is not sufficient, and when it exceeds 10 parts by weight, there is a problem in that workability and adhesiveness are deteriorated.

The hollow beads may be inorganic fine particles having a size of 1 ~ 40㎛, preferably the inorganic fine particles may be at least one selected from the group consisting of borosilicate glass, silicate ceramics and aluminosilicates as hollow silica. In addition, the hollow bead is preferably included 1 to 5 parts by weight based on 100 parts by weight of acrylic resin. If the content of the hollow bead is less than 1 part by weight based on 100 parts by weight of the acrylic resin, the heat shielding effect is insufficient. If the content of the hollow bead exceeds 5 parts by weight, the effect of increasing heat insulation is insignificant, and the strength of the composition may be lowered. .

On the other hand, the volcanic ash is a material having a porous structure to form a myriad of air layers can exhibit the heat shielding effect to lower the thermal conductivity of the air layer. However, the volcanic ash does not have good dispersibility, and when included in the composition, the volcanic ash is not evenly dispersed and aggregated. Accordingly, the present invention is to improve the dispersibility of the ash, to modify the surface of the ash in order to improve the mixing and adhesion between the ash and the packaging composition.

The volcanic ash may be surface-modified by immersion in a reaction solvent in which a silane coupling agent is dissolved in an organic solvent. Preferably, the silane coupling agent may be contained in the organic solvent 5 ~ 10wt% compared to the volcanic ash. When the content of the silane coupling agent is less than 5 wt% of the ash, the surface of the ash is not sufficiently modified, and when the content of the silane coupling agent is more than 10 wt%, the effect of surface modification by weight is not preferable. Moreover, stirring time is 1 to 5 hours, and it is preferable that stirring temperature is 100-150 degreeC. If the stirring time or the stirring temperature is less than the above range, the surface of the ash is not sufficiently modified, and if it exceeds the above range, the surface modification effect according to the time or temperature is not preferable.

At this time, the organic solvent is dichloromethane, tetrahydrofuran (THF), ethanol (ethanol), methanol (methanol), acetone (acetone), dimethylformamide (dimethylformamide; DMF), dimethylsulfoxide (dimethylsulfoxide) DMSO) and dioxane may be one or more selected from the group consisting of.

In addition, the surface-modified volcanic ash is preferably included 5 to 20 parts by weight based on 100 parts by weight of acrylic resin. When the content of the surface-modified volcanic ash is less than 5 parts by weight with respect to 100 parts by weight of the acrylic resin, the heat shielding effect is insufficient, and when it exceeds 20 parts by weight, the adhesive force of the packaging material composition may be weakened, which is not preferable.

That is, the pavement packaging material composition of the present invention is characterized by being able to exert an excellent heat shielding effect by including the surface-modified volcanic ash.

The crosslinking agent is ethylene glycol dimethacrylate, trimethylolpropane trimethacrylate, pentaerythritol dimethacrylate, pentaerythritol trimethacrylate, diallyl phthalate, divinylbenzene and triallyl cyarate. It may be one or more selected from the group consisting of. In addition, the crosslinking agent is preferably included 1 to 5 parts by weight based on 100 parts by weight of the acrylic resin. If the content of the crosslinking agent is less than 1 part by weight based on 100 parts by weight of the acrylic resin, the physical properties of the packaging material may be deteriorated. If the content of the crosslinking agent is more than 5 parts by weight, the processability and physical properties of the packaging material may be deteriorated due to excessive crosslinking. .

The inorganic filler may be at least one selected from the group consisting of silica sand, aluminum hydroxide, silica, mica, talc, calcium carbonate, clay and asbestos powder. The inorganic filler is preferably included 30 to 50 parts by weight based on 100 parts by weight of acrylic resin. When the content of the inorganic filler is less than 30 parts by weight with respect to 100 parts by weight of the acrylic resin, the viscosity, heat resistance, durability and workability of the packaging material are lowered, and when it exceeds 50 parts by weight, the adhesive strength of the packaging material composition is not preferable.

The curing agent may be at least one selected from the group consisting of benzoyl peroxide, lauryl peroxide, acetyl peroxide and octyl peroxide, and the curing agent may include 3 to 10 parts by weight based on 100 parts by weight of acrylic resin. . When the content of the curing agent is less than 3 parts by weight with respect to 100 parts by weight of acrylic resin, curing does not occur sufficiently, and when it exceeds 10 parts by weight, the pot life may be shortened due to rapid curing, which is not preferable.

The packaging material composition may further include a color pigment. The coloring pigment may be used without any limitation as long as the inorganic pigment is commonly used, and the amount of the pigment may be adjusted and used as necessary, so it is not limited. For example, the inorganic pigments include reddish brown pigments such as iron oxide, yellow pigments such as zinc sulfide, green pigments such as chromium oxide and chromium hydroxide, ultramarine pigments such as sodium aluminosilicate, blue pigments such as cobalt oxide, titanium oxide, and oxidation One kind or two or more kinds selected from the group consisting of white pigments such as zinc may be used and mixed, and the blending amount may be arbitrarily adjusted according to the degree of color expression.

In addition, the packaging material composition of the present invention may further contain other other additive components. The other additives may be reaction accelerators, plasticizers, dispersants, antisettling agents or antifoaming agents.

Color or pattern may be formed on the surface of the packaging material composition in step 4, wherein the color or pattern may be coated using a stamp or spray stencil technique.

The heat-shielding pavement composition provided by the present invention includes a surface-modified volcanic ash that forms a myriad of air layers, thereby effectively blocking and reflecting infrared rays to lower the temperature rise of the road.

In addition, when the paving composition is newly formed or applied on the asphalt and concrete roads, it is possible to form a pattern on the road surface for better road paving.
