The bottom resin layer, the top resin layer and the bottom resin layer will be described as follows.

(1) bottom resin layer

The bottom resin layer is a composition in which the main body and the hardener are separated and prepared in two parts, and are mixed with the aggregate to prevent slippage to generate substantial friction.

The main components of the bottom resin layer include 40 to 60% by weight of modified epoxy resin, 12 to 18% by weight of reactive diluent, 8 to 12% by weight of pigment, 13 to 27% by weight of filler, and 3 to 7% by weight of antisettling agent. It is made, including.

In this case, the modified epoxy resin may be implemented with a modified BPA epoxy resin. But the modified epoxy resin is not. It is preferred that the modified BPA epoxy resin is 24 to 36 parts by weight, rubber modified epoxy resin 8 to 12 parts by weight, and urethane modified epoxy resin 8 to 12 parts by weight.

The modified BPA epoxy resin is a bisphenol-A type epoxy resin, which is superior in flexibility to ordinary epoxy resins and has a medium viscosity (~ 600 cps). Such modified BPA epoxy resins have high wear resistance, fast curing speed, and excellent adhesive strength.

The rubber-modified epoxy resin has flexibility in itself, thereby giving flexibility to the bottom resin layer. Accordingly, even if an impact is applied by a heavy object such as a vehicle after the bottom resin layer is formed, damage to the bottom resin layer can be minimized.

The urethane-modified epoxy resin is used for the purpose of improving plasticity as a resin produced by reacting urethane with epoxy.

Reactive diluents mainly aim to reduce the viscosity of the resin, but there are a variety of butyl glycidyl ether (BGE), phenyl glycidyl ether (PGE), Modifide-Tert-Carboxylic Dlycidyl Ester, and the like.

The pigment is added to realize the non-slip layer to be packaged in the desired color. It is preferable to adopt such a pigment that can match the color of the road surface to be repaired. For example, there is carbon black having excellent weather resistance.

Fillers improve the mechanical properties of the resin, in addition to cost reduction, reduction of thermal expansion rate, reduction of curing shrinkage rate, control of calorific value during curing, improvement of adhesiveness and the like. These fillers are those commonly used such as stone powder, calcium carbonate, slaked lime, talc, alumina, and other waste materials, and affect the hardness depending on the average particle size, the smaller the particle size may affect the hardness increase. .

 The antisettling agent is a type of dispersant which is added to prevent the precipitation of raw materials such as fillers and pigments having a relatively high specific gravity during the storage period after the main production. As such a sedimentation inhibitor, a polyamide-based sedimentation inhibitor is used.

The hardener which comprises a bottom resin layer contains 35-53 weight% of modified aromatic special amine hardeners, 35-53 weight% of modified aliphatic amine hardeners, and 9.5-14.5 weight% of aliphatic tertiary amines.

The modified aromatic special amine curing agent is a raw material used to secure fast curing and hardness properties, and has some flexible properties despite being aromatic.

Modified aliphatic amine hardeners are used to maximize flexible properties although the curing speed is rather slow.

Aliphatic tertiary amines are used to maintain a fast curing rate, and are generally used as curing accelerators such as amines.

The main ingredient and the hardener produced by the above production method are mixed and used in a weight ratio of 1: 0.1 to 0.5 in the field.

(2) Top Resin Layer

The top resin layer is a composition in which the main body and the hardener are separated and manufactured in two parts. The top resin layer has a non-yellowing property that is not modified by ultraviolet rays, and is formed on top of the bottom resin layer so that the bottom resin layer is not modified.

The main body constituting the top resin layer comprises 56 to 84% by weight of an acrylic polyol resin, 0.8 to 1.2% by weight of a curing accelerator (Tin-based), and 15.2 to 42.8% by weight of a diluent.

Acrylic polyol resin is resin obtained by superposing | polymerizing at 120-135 degreeC using a nonfunctional acryl monomer, a carboxyl acryl monomer, and a hydroxyl acryl monomer as an initiator, and becomes reactive with an isocyanate by the functional group of a hydroxyl acryl monomer. The acrylic polymer resin has the advantage of obtaining various resin properties by adjusting the molecular weight, acid value, and Tg (glass transition temperature), and has excellent weather resistance and wear resistance.

A hardening accelerator is added in order to enable fast hardening, and a metal catalyst is used a lot. The hardening accelerator is used for the purpose of shortening the curing half-life when the main material is mixed with the hardening agent to complete the urea / urethane coating composition, thereby reducing the vehicle time limit and improving the field applicability. As such a curing accelerator, a dibutyl tin dilaurate (DBTDL) which is a tin compound is used.

The diluent is a raw material added in order to reduce the viscosity of the main material and to improve roller coating property (workability), and was used in combination with a solvent of a kind having a property of not dissolving asphalt. Such diluents include toluene, ethyl acetate and the like.

The hardening agent which comprises a top resin layer contains 40 to 60 weight% of polyisocyanate resins, and 40 to 60 weight% of diluents.

Polyisocyanate resin is an HMDI trimer type resin having no isocyanate ring, and is excellent in compatibility with acrylic resin, has a fast drying speed, and has excellent weather resistance.

As a diluent, it is used for viscosity adjustment of the polyisocyanate resin of a hardening | curing agent, For example, xylene, MEK, etc. are mentioned.

The main ingredient and the hardener prepared by the method described above are used in an amount of 1: 0.1 to 0.5 by weight.

(3) sewerage

The bottom resin layer is a composition prepared in a one-part form, and when the state of the road surface is poor, reinforcing the road surface improves the adhesion between the bottom resin layer and the road surface.

Such a bottom resin layer is 11 to 17% by weight of polyether polyol resin, 4 to 6% by weight of crosslinking agent, 16 to 24% by weight of diisocyanate (TDI), 52.887 to 68.969% by weight of diluent, and 0.001 to 0.003% by weight of reaction stabilizer. %, 0.01-0.03 weight of hardening accelerators, and 0.02-0.08 weight% of antifoamers.

The polyether polyol resin has an average molecular weight in the range of about 400 to 5,000, and one having 2 to 3 hydroxyl groups (—OH) is used. In this embodiment, a polyether polyol resin having an average molecular weight of 1,000 and containing two hydroxyl groups (-OH) is used. This polyether polyol resin reacts with the diisocyanate component of the curing agent described later to induce a urethane bond.

The cross linker is used to increase chemical bonds, and uses trimetylol propane and / or the product name 1.3BG. In the present embodiment, in order to maximize the high hardness and hardening properties, trimethylol protane and 1.3BG are used in the same. Since the crosslinking agent has a molecular weight of 100 or less and a single molecule and 2 or 3 functional groups, It is an optimal raw material for use as a crosslinking agent. Trimethylol protan is used after dissolution by heating to about 60 ° C. in a solid state at room temperature, and 1.3BG is used immediately because it is liquid at room temperature.

Diisocyanate is a compound containing an isocyanate group (-NCO). The most commonly used compounds such as diisocyanates are toluene diisocyanate (TDI) and diphenylmethane-4,4-diisocyanate (MDI), and many other aromatic and aliphatic diisocyanate compounds exist. do. When considering the molecular weight and functional groups of the above isocyanate compound, it is easy to control the reaction rate. In this embodiment, toluene diisocyanate (TDI) is used. These isocyanate compounds are the main raw materials that react with the polyols used in the main agent and the curing agent to produce urea and urethane.

The reaction stabilizer is for reducing the amount of heat generated during the urethane reaction. Heat is generated during the urethane reaction. Especially, since the amount of the crosslinking agent is rather high due to the characteristics of the product and two kinds are used, there is a fear of severe heat generation during the urethane reaction, and thus it is used to prevent this.

A hardening accelerator is added in order to enable fast hardening, and a metal catalyst is used a lot. In this embodiment, DBTDL, which is a Tin compound most used as a curing accelerator between a urethane prepolymer and water in air, is used. The above curing accelerator promotes the reaction when the product (urethane prepolymer) is exposed to the air, thereby improving the field applicability (reducing the vehicle time limit by increasing the curing speed).

Antifoaming agents are used to remove bubbles generated during the reaction and to simultaneously remove bubbles generated upon application to the adherend.

The diluent was used in combination with a solvent having a property of not dissolving asphalt as a raw material added in order to lower the viscosity and improve roller paintability (workability) and adherend penetration.

As other additives, some moisture absorbents, such as moisture absorbents, are used to keep the color clear and to maintain the storage stability when the product is packaged and stored.

Hereinafter, embodiments of the present invention will be described in detail.

Example 4 Non-Slip Layer Packaging

The bottom resin layer, the bottom resin layer and the top resin layer can be manufactured in the same manner as above, and the non-slip layer is formed on the road surface by using them. To this end, the following processes are carried out sequentially.

(1) remove foreign substances

Remove any gum, oil, or other foreign matters on the road using a hand grinder.

(2) cleaning

In order to improve the adhesion between the resin and the road surface during construction, use a circular plate vacuum cleaner to brush the road surface about once and then clean it with a suction cleaner.

(3) Crack repair

If a crack occurs on the road surface of the construction site, the crack must be repaired. To repair the cracks, clean the cracks using a high pressure air compressor and dry sufficiently with a gas hot air blower to dry the water under the cracks. Afterwards, holes at the ends where the construction part and the crack part coincide are made 1 cm deeper than the depth of the crack and slightly larger than the width of the crack, and by filling the crack-specific filling resin, air from the surrounding part is not introduced. It should not be allowed. Then, after confirming the dry state, the asphalt crack repair agent is injected into the crack site through the injection pump. After the asphalt-only crack repair material is injected to the road surface, the soft nonwoven fabric is cut in the shape of cracks, and then bonded to the cracked area, attached using a small brush, and pressed with a roller to be attached to the road surface.

(4) Application of sewer resin layer

If the road surface is not in good condition, the road surface must be reinforced by applying a sewer layer according to the road surface condition. This is to prevent the lifting phenomenon of the bottom resin layer that is advanced later.

(5) Floor resin layer application

However, depending on the type of work on the road, the general spraying method may be used. According to the type and classification of the road, the appropriate color and aggregate size should be set so that excessive curvature does not occur. After the aggregate is sprayed, the roller is pressed using a roller.

(7) aggregate recovery

After spraying the aggregate, check the hardening and clean the aggregate and the surrounding area using the cleaning basket.

(8) Top coat resin coating (for general spray)

In order to prevent the absorption of aggregates in rainy weather, using a yellowing-free coating agent to maintain the color of the existing aggregates unchanged for ultraviolet light and to increase the adhesion to maintain a long life.

In forming the anti-slip layer through the sequential process described above, a joint having a width of 3-5 cm is formed at regular intervals for elongation of the asphalt. However, when using the aggregate coated with an inorganic pigment, there is no need to apply a top coat resin layer because there is no modification by ultraviolet rays.
