The present invention relates to a pressure-sensitive adhesive composition, a tape and a composition, and a tape manufacturing method for repairing road cracks, and in particular, after sufficiently infiltrating into a highly concentrated and improved asphalt compound specially processed, by controlling a constant thickness and length according to a standard at room temperature by air cooling. The present invention relates to a pressure-sensitive adhesive composition, a tape, a composition, and a tape manufacturing method.

In general, concrete, asphalt, etc. have been used to pave the road, but this occurs due to the change in temperature and precipitation due to the four seasons change and repeated loads.

Therefore, in areas with frequent temperature changes, such as Korea, road cracks often occur, so it is difficult to check them with your own eyes. An apparatus for detecting a crack by continuously photographing a road surface of a pavement through a mounted image photographing camera may be proposed.

On the other hand, when a crack occurs in a pavement or the like, the asphalt-based suture is repaired by an injection method for the purpose of imparting adhesiveness and waterproofness to the cracked portion. However, the conventional repairing material does not have sufficient permeability and adhesion. Therefore, fine cracks, cracks, or gaps deep inside the package to be repaired do not penetrate into the cracks to be repaired, which causes a problem of insufficient strength and durability.

In particular, the top of the crack prevents the penetration of the periphery of the crack, so that the cover part is worn out or dropped due to frequent traffic, and the rainwater penetrates. There were also problems that worsened.

In addition, in order to repair and reinforce the cracks of the concrete structure, the foreign material (for example, dust, moss, or concrete debris, etc.) is scraped around the cracks with a wire broth, and then heaves around the cracks and cracks. For example, a spatula-shaped object made of a steel plate or the like is used to repair or reinforce the crack by injecting or applying a sealing agent or cement mortar, so that it is injected into a crack of a concrete structure or a crack or breakage of a concrete structure. It takes more than 24 hours to harden the sealing agent or cement mortar applied around the part, which leads to excessive work time, thereby increasing the construction cost for repairing or reinforcing the cracked or damaged part of the concrete structure. There was a problem.

The present invention is to solve the above problems, by providing a tape using the adhesive composition, the adhesive composition which can finish the work in a short time by reinforcing the crack portion of the coating by a simple construction method to attach the tape And to provide a tape and a method for manufacturing thereof.

Hereinafter, the main materials applied to the present invention will be briefly described.

Asphalt is a residue when most of the volatile components of petroleum oil evaporate, and is classified into natural asphalt and petroleum asphalt.

First, natural asphalt is produced in the form of residue after the hard part of petroleum is evaporated by natural force (solar heat, geothermal heat, etc.), and the output is extremely small, depending on the state of the lake, asphalt, rock Asphalt, Sand Asphalt, Asphaltite, etc.

(A) Lake asphalt

Asphalt is exposed to the surface in the form of a lake, such as Trinidad Asphalt in South America and Bermuez Asphalt in Venezuela.

(B) Rock asphalt

Asphalt is infiltrated into porous limestone and sandstone. Asphalt content is about 10%, and it is used for road pavement.

(C) Sand asphalt

Asphalt is infiltrated into the sand layer.

(D) Asphaltite

It is a generic term for pure asphalt that has been denatured with asphalt for many years due to oil seeping into the cracks of rocks. Gilsonite, Glance Pitch and Grahamite.

Next, petroleum asphalt is obtained from petroleum products such as petroleum refining. Straight asphalt, asphalt cement, cutback asphalt, emulsified asphalt, blown asphalt, modified (Modified) can be divided into asphalt and the like.

(A) Straight asphalt

The final residue obtained by distilling crude oil in atmospheric pressure distillation column (CDU) and distilling pressure residue (AR) again under reduced pressure contains a lot of bitumen which is not decomposed. This is called straight asphalt and is used as a raw material for various petroleum asphalt. Used.

(B) asphalt cement

Asphalt used for road pavement, produced by adjusting operating conditions in VDU. Currently, AP-3 with 80-100 intrusion and AP-5 with 60-80 intrusion are used in Korea. Recently, AP-3 has been the dominant market. To prevent this, the demand for AP-5, which is considered to have a relatively high packaging performance at a high temperature, is increasing.

(C) cut back asphalt

Asphalt cement, a road paving asphalt, is semisolid at room temperature, so it is inconvenient to use it when it is mixed with the aggregate or heated when it is sprayed. Rapid Curing (RC), Medium Curing (MC) and Slow Curing (SC) are available depending on the type of solvent used to make the liquid at room temperature. This is mostly used.

(D) oil painting asphalt

The asphalt is made of fine particles and dispersed in water. An emulsifier is required to maintain the dispersed state without the asphalt phase separation phenomenon in the water. If the emulsifier is charged with positive charge (+), it is called cationic emulsion asphalt, and if it is charged with negative charge (-), it is called anion emulsion emulsion. Most of domestic products are cationic emulsion asphalt.

(E) blown asphalt

Compressed air is blown into heated straight asphalt or hard vacuum distillation residue oil (VR) to cause condensation polymerization between the asphalt molecules, thereby increasing the molecular weight. Compared with asphalt cement, it has a low temperature sensitivity and is excellent in solid state, heat resistance, and durability at room temperature. It is widely used in industrial fields such as building materials, and is used as a joint filler in road paving.

(Bar) modified asphalt

Asphalt which improves pavement performance by adding synthetic resin or rubber to asphalt cement for use in paving road for specific use. It is used for paving bridges, overpasses and heavy vehicle roads. Drainage asphalt is also used to solve problems such as pooling. The super pallet developed and commercially sold by the company is SBS Polymer modified asphalt, a synthetic rubber system.

Asphalt compound is a asphalt with high temperature sensitivity by mixing special additives with petroleum asphalt, divided into four types according to the size of the temperature sensitivity, there are four kinds from the highest temperature sensitivity to the smallest bar, one type is relatively soft It is used for indoor indoor and underground waterproofing, two types are used for waterproofing indoor structures in general areas, three types are used for waterproofing outdoor structures in hot areas, and four types are used for waterproofing outdoor structures in cold areas.

Since the synthetic rubber is used to make rubber products, the properties as vulcanized rubber products, namely elasticity, cold resistance, aging resistance, heat resistance, oxidation resistance, ozone resistance, oil resistance (耐油 性) ), Chemical resistance, etc. are required. In most cases, the processing method is the same as that of natural rubber, and it is squeezed by a roll to control the molecular weight to increase plasticity and adhesiveness.In addition, fillers such as carbon black, zinc oxide and vulcanizing agent are used. Sulfur and vulcanization accelerators are mixed and crushed again.

The Kumaron resin is a compounding agent, which increases the adhesiveness of the surface of the compound, and should be compatible with the rubber material, the adhesiveness should be maintained for a long time, and the type of tackifier is a guarone-indene resin, phenol-form Aldehyde resins, xylene-formaldehyde resins, polyterpine resins, petroleum hydrocarbon resins, rosin esters, etc. In particular, guarone resins are widely used as tackifiers for SBR, NBR, CR, and EPDM. -It is known to have excellent alkali resistance, water resistance and electrical insulation.

The calcium carbonate is calcium carbonate, and salt refers to a salty substance. The calcium carbonate is the most abundant salt in nature, and is present in marble, limestone, shells, egg shells and corals. Generally, it is a colorless crystal or white solid, which is decomposed at 825 degrees. When calcium carbonate is heated, it generates carbon dioxide and obtains quicklime (CaO), which is used industrially. It is used a lot. That is, as limestone marble, it is used as various neutralizing agents (neutralizing agent: a substance which acid and base meet and become neutral), such as a main raw material of cement, a raw material of calcium oxide (lime), and a steel building material. Precipitated calcium carbonate is used in pigments, paints, toothpastes, etc. in white pigments (pigments: pigments) and water-based paints (pigments that dissolve in water).

Looking at the manufacturing step of the specific adhesive composition is as follows.

As a first step, the asphalt resin, the asphalt compound, and the oil for tackiness preparation are prepared and mixed in a stirrer, where the mixing ratio is 69% by weight asphalt resin, 1% by weight asphalt compound, 1.5 weight tackiness oil %to be.

In the above, the asphalt resin is a resin having a relatively close physical property, and it is preferable to use AP-3 having an infiltration degree of 80-100. The oil for enhancing adhesion is a material that induces the asphalt resin to stick well.

In the present invention, the ingredients are added to a stirrer and mixed, and then the mixed material is heated to 150 ° C. to 160 ° C. for about 2 to 3 hours as a second step. If it is below the temperature range, the mixing is not performed at all, and if it is above the temperature range, the asphalt strength falls.

Therefore, the present invention is heated by a relatively weak heat for a long time to achieve a proper material mixing of asphalt.

After the heating for about 2 to 3 hours as described above, the second material group is added, and as a third step, 12% by weight of SBS synthetic rubber and 1.5% by weight of guaron resin are mixed in an agitator.

In addition, after mixing the SBS synthetic rubber and the Kumaron resin, the mixed material is heated as 200 ° C. to 210 ° C. for 2 hours as a fourth step. If the temperature is less than the temperature range is because the mixing of the synthetic rubber is not made smoothly, if the temperature is more than the temperature range because of the change of properties of the synthetic rubber does not occur well.

As described above, the heating time is set to 2 hours while heating to a constant temperature, so that the synthetic rubber and the asphalt resin are sufficiently mixed well.

When the step is completed, the transfer to another tank and proceeds to the fifth step, in the fifth step is made by mixing 15% by weight of calcium carbonate.

In the present invention, the calcium carbonate was used to compensate for the elasticity of the composition to cause a cushioning action.

When the composition is completed using the manufacturing procedure as described above to produce a tape applied to the road cracking portion using the bar, the tape is the adhesive composition layer 20 disposed in the center; A release paper layer 30 attached to a lower portion of the adhesive composition layer and made of a paper or a silicone film to temporarily protect the composition layer; It is attached to the pressure-sensitive adhesive composition layer, it consists of a protective layer 10 to protect the pressure-sensitive adhesive composition.

In the adhesive composition layer 20 is 2.0 to 2.5mm, the release paper layer 30 is 0.05 to 0.1mm, the protective layer 10 preferably has a thickness of 0.05-0.1mm bar, which is the thickness of the composition Since it should not protrude from the road is about 2.0-2.5mm is most preferred, the release paper layer 30 and the protective layer 10 is about 0.05-0.1mm is suitable. This is because the release paper layer 30 and the protective layer 10 need to maintain a minimum thickness, and since the release paper layer 30 is peeled off before attaching to the road, the crack reinforcement tape is completed to a thickness of 2.6 mm or less as a whole. .

In addition, the protective layer 10 is preferably a black P.P woven fabric or a polyester nonwoven fabric, in order to provide an appropriate friction force without slipping on the vehicle.

Looking at the overall manufacturing process of the road crack reinforcing tape of the present invention.

A first step of mixing a first material of 69% by weight of an asphalt resin, 1% by weight of an asphalt compound, and 1.5% by weight of an oil for strengthening adhesion into a stirrer;

A second step of heating the mixed material at about 150 ° C. to 160 ° C. for 2-3 hours;

A third step of mixing 12% by weight of SBS synthetic rubber and 1.5% by weight of guaron resin;

A fourth step of heating the mixed material at about 200 ° C to 210 ° C for 2 hours;

A fifth step of mixing 15% by weight of calcium carbonate after transferring to another tank;

A sixth step of spraying in an extruder while maintaining a temperature of 200 ° C .;

A seventh step of attaching the silicon release paper to attach the silicon release paper to the lower part simultaneously with the spraying step;

An eighth step of laminating a black P.P woven fabric or a polyester nonwoven fabric at the same time as the spraying step;

A ninth step of drying the three-layer tape by normal temperature air cooling;

The tenth step is to cut to a constant length.

The extruder is provided with a heating means capable of maintaining a proper temperature and a compression means capable of imparting a high pressure, and additionally, a temperature and pressure control device and a time control device are added, thereby adhering to an appropriate temperature and pressure. The composition can be ejected to the outside.

In this case, since the adhesive composition is in a solid state, there is no problem of laminating a polyester nonwoven fabric on the adhesive composition and attaching a release paper below. The product is produced in an appropriate length, dried at room temperature, and then cut into a constant length product. To complete.

As described above, the present invention provides the road cracking tape having excellent durability, thereby providing the effect of maintaining flexibility and elasticity to the maximum.

In addition, the wide temperature resistance is excellent in cold resistance and heat resistance, so it does not break at low temperatures or flow at high temperatures to provide the most suitable effect in the domestic climatic conditions with a large temperature change.

In addition, the excellent elasticity and elongation is excellent elasticity like general vulcanized rubber, fast resilience against physical invasion of the outside, and excellent elongation to show the high conformity to the change of the structure by supplementing the durability of the road crack reinforcement tape according to the seasonal change to the maximum do.

In particular, the present invention can secure the economical because of the simple construction using the tape, as well as to minimize the construction period and the number of construction personnel can reinforce the crack of the road at the lowest construction cost.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
