Description

Copolymerization of acrylic resin binder having non-slip paint and grooving method of road using non-slip paint}

The present invention relates to an anti-slip agent using an acrylic copolymer resin and a grooving method of a road using the anti-slip agent, and more particularly, to a modified urea solution and a dioxide as a thixotropic agent. A non-slip agent is formed by adding silicon, silica sand and steelmaking slug, and the anti-slip agent is formed to protrude the grooving by a masking method so that the grooving can be formed on many roads in a short time without breakage of the road. The present invention relates to a non-slip agent manufacturing method and a grooving construction method of the road using the same, which not only minimizes traffic congestion due to grooving, thereby increasing workability, but also significantly reduces manpower and cost during grooving construction.

In addition, steelmaking slug used as a sieving pigment is produced as a by-product in the production of steel, and it is changed into particles that block free CaO from general steelmaking slug by treating with SAT (Slag Atomizing Technology) method. Does not cause problems This steel slag is a stabilized eco-friendly material that has been found to dissolve snow relatively quickly due to higher surface temperature than the use of conventional extender pigments when used for anti-slip application.

In general, grooving is a pavement surface treatment method first developed by the US Aeronautics and Space Administration for aircraft safety in the 1960s. It forms a three-dimensional groove on the pavement surface of airports and roads, creating a tire pattern-like effect. "Road Safety Technology" is applied to prevent water film phenomenon and improve drainage, to prevent other slip, to prevent freezing, to improve driving safety, and to reduce noise.

The grooving method is a method of forming a groove of a certain standard on the pavement surface of a road and a runway, and is a part of various pavement surface treatments. It is divided into texturing and grooving according to the width of.

The above grooving construction is an excellent technology for preventing slipping, curving away from curved roads, preventing freezing, preventing water film, decelerating warning, and noise countermeasures. By applying the grooving method, the risk of traffic accidents can be minimized.

As the application area of each grooving purpose, the section which has low road friction coefficient, the section which needs to improve drainage, the risk of freezing accident, the risk of deviating from the vehicle, and the need to improve the grip force, the curve section, the section which needs to improve steering, the ramp, etc. It is constructed in areas that need an anti-slip facility, areas that need to be alert to drivers, and areas that require measures to reduce traffic noise.

As a method for forming the groove on the road as described above, the groove-type groove 11 is formed on the road surface of the road by using a grooving machine as in FIG. No. 2006-71383 (published date: June 26, 2006), and as another construction method is a coating type to apply a non-slip paint to the road surface as shown in Fig. 1 (b) to give a grooving effect Grooving 12 (Korean Patent No. 741146 (Registration Date: July 12, 2007), Republic of Korea Patent Publication No. 2009-106172 (Publishing Date: October 08, 2009) of the two forms.

In the case of forming the grooved groove 11 directly on the road surface as shown in (a) of FIG. 1, the defects are less generated during long-term use, the construction cost is low, and the drainage performance is good in rainy weather. Over time, foreign matters are accumulated in the grooves, and the effect is reduced. In rainy weather, water film phenomenon occurs, causing accidents.

In addition, there is a problem in that, in the winter grooves, as the human body expands with the ice at the same time as the ice, the grooving groove is destroyed or the road damage is inevitable due to the load of the vehicle. It would be good to cause arousal for safe driving by treating it with a color that is easy to detect, but at present there is a problem that aesthetics are not good.

As shown in (b) of FIG. 1, the construction method of the paint-type grooving 12, which obtains the grooving effect by applying an anti-slip paint to the drawing of the road, has an advantage of easy selection of various colors and easy construction.

In addition, the Republic of Korea Patent Publication No. 2010-98917 (published date: September 10, 2010) is a technique for forming a groove groove on the road surface of the road, and applying a Zion pigment to the groove groove, but grooving work Due to the double operation, such as the application of the paint and the construction cost is significantly increased there is a problem that the practicality is lowered.

In addition, the binder used in the paint-type grooving method, in which the anti-slip paint is applied to the drawing of the road, has been transformed into various types over time, and the UPE (unsaturated polyester) type Anti-slip agents using various binders have been developed, such as epoxy, urethane, other mixed, modified and hot-melt types.

In the case of the UPE type, after the pavement is hard, there is a disadvantage in that the adhesion is poor and the winter cracking problem easily occurs, and the discoloration easily comes. Epoxy type has good adhesion, but hardness becomes stronger with time, which leads to cracks and poor adhesion as well as poor weather resistance due to the properties of epoxy resins. appear.

In the case of the urethane type, there is a problem in that the coating film flexibility and the construction properties without a great influence on the temperature change for the purpose, but the overall physical properties are weak when exposed to moisture for a long time. The coating film also exhibits some degree of flexibility in the early stages of operation, but there is a problem of a tendency to gradually change over time.

The present invention is to improve the road surface adhesion performance and long-term physical properties by using an acrylic copolymer as a binder in order to solve the conventional problems as described above, modified urea solution and silicon dioxide as a thixotropic agent and silica sand with excellent durability pigment It is a technical problem to use steelmaking slug to improve the wear resistance of an anti-slip agent with a long time.

Shall be.

In addition, the present invention by the masking method of the anti-slip agent made of acrylic copolymer resin as a masking method, the anti-slip agent applied to the surface of the road hardened grooving is formed in the form of a protrusion so that the road of many lengths in a short time without breakage of the road It is possible to form grooving on the floor, thereby improving construction, minimizing traffic congestion due to grooving, significantly reducing manpower and cost, and driving a variety of colors that can cause the driver to be alert. It is technical problem to make it possible.

In addition, when the steelmaking slug is mixed, the surface temperature is higher than other extender pigments, so that the heated snow is dissolved relatively quickly.

The present invention is 20 to 40% by weight of acrylic copolymer resin, 0.1 to 3% by weight of silicon dioxide, 0.1 to 2% by weight of antifoaming agent, 0.1 to 1.0% by weight of polysiloxane, 1 to 10% by weight of colored pigment, and 10 to 10% of filler. 20 wt%, modified urea solution 0.1-3 wt%, plasticizer 1-5 wt%, silica sand 20-50 wt%, steelmaking slug 10-40 wt%, curing accelerator 0.1-1.0 wt%, curing agent 0.4 It is characterized by consisting of ~ 3.0% by weight.

Hereinafter, the grooving construction method of the road using an anti-slip agent according to the present invention will be described in detail with reference to FIGS. 2 to 5.

The antislip agent used in the present invention is 20 to 40% by weight of acrylic copolymer resin, 0.1 to 3% by weight of silicon dioxide, 0.1 to 2% by weight of antifoaming agent, 0.1 to 1.0% by weight of polysiloxane, and 1 to 10% by weight of colored pigment. WHEREIN: 10-20 weight% of fillers, 0.1-3 weight% of modified urea solutions, 1-5 weight% of plasticizers, 20-50 weight% of silica sands, 10-40 weight% of steelmaking slugs, and 0.1-1 hardening accelerators It consists of weight% and 0.4-3.0 weight% of hardening | curing agents.

The acrylic copolymer resin is a binder component that protects the firmness and possession of the coating film in the non-slip agent, when added to less than 20% by weight can not maintain the firmness of the coating film, when added in excess of 40% by weight Its function is poor, and after a long period of time, it may fall out of the asphalt, causing cracks.

The silicon dioxide is a raw material that prevents the filler or the anti-skid raw material from being deposited to the floor during storage and forms a slip roughness, and when the silicon dioxide is added in an amount less than 0.1% by weight, the filler or silica sand steel slug is precipitated to the bottom. In the end, it causes a hard cake (Hard cake) problem when used, and when added in excess of 3% by weight, it is preferable to add it within the range of 0.1 to 3% by weight because it has a problem of poor workability due to its high viscosity.

The antifoaming agent is used to remove bubbles in the coating film using incompatible properties. In the present invention, it is preferable to use the silicone antifoaming agent within the range of 0.1 to 2% by weight.

When the polysiloxane is added less than 0.1wt%, the dispersibility of the sieving and pigments and the antifoaming performance of the product are deteriorated, and the anti-slipper is not sufficiently wetted to reduce the adhesion, and when it is added more than 1wt%, the product strength is affected. It is preferable to add within the range of 0.1 ~ 1wt% because it will have.

The colored pigment is intended for maintaining the appearance of the non-slip sheet and visibility in the daytime, it is preferred to add within the range of 1 ~ 10wt%.

The filler is a component that controls the strength, abrasion resistance, workability, and viscosity of the coating film. In general, when the amount of the additive is increased, adhesion is reduced and the coating film is weakened. In addition, too little use causes insufficient problems in viscosity, workability, strength and the like. In order to maintain appropriate strength, abrasion resistance and workability, it is preferable to add within a range of 10 to 20% by weight.

The modified urea solution is a component that forms a three-dimensional network structure to improve the thixotropy of the anti-slip agent to form roughness when forming a coating film, and when added outside the range of 0.1 to 3% by weight, the thixotropy of the anti-slip agent is reduced. Roughness is not formed.

The plasticizer has a role of appropriately adjusting the coating flexibility during the construction of the anti-slip agent, when the addition of less than 1% by weight can be easily cracked due to the strong coating, and when added to more than 5% by weight, the coating becomes flexible and relatively easy to wear Since there is a problem to be added, it is preferable to add within the range of 1 to 5% by weight.

The silica sand and steelmaking slug are used as the main aggregate of the anti-slip agent to increase the surface friction after coating film formation, thereby improving the anti-slip performance. When added in excess of 50% by weight, the surface friction is increased. When it is applied to the coating, the workability is insufficient and the adhesion to the coating film is decreased.When it is added less than 20% by weight, the anti-slip performance is deteriorated. It is preferable to add.

The hardening accelerator plays a role of promoting winter drying at a low temperature, and when it is added in an amount less than 0.1 wt%, the drying is slow in winter. Rapid hardening may also cause discoloration or cracking. Therefore, it is preferable to add within the range of 0.1 to 1% by weight.

The curing agent has a role of solidifying (drying) the anti-slip agent by the polymerization reaction when mixed in the main material, when the addition is less than 0.3% by weight, there is a problem that the drying is slow, when more than 2% by weight is added to rapid drying Since workability problems may occur and discoloration and cracking problems may be caused, it is preferable to add within 0.4 to 3% by weight.

Acrylic binder of the binder function is 50 to 83% by weight of methyl methacrylate monomer (MMAM), 10 to 35% by weight of butyl acrylate monomer (BAM: Butyl Acrylate Monomer), and 2 ethyl hexyl acrylate It consists of 5-20% by weight of monomer (2-Ethyl Hexyl Acrylate Monomer), 1-5% by weight of acrylic acid (AA), and 0.01-0.3% by weight of azobisIsoButylroNitride (AIBN).

The acrylic copolymer resin polymerizes each component at 75 to 80 ° C., wherein the glass transition (Tg) temperature is adjusted to 40 ° C. to 60 ° C., and the polymerization reaction (Hydroquinone) is 0.1 to 3 ppm and di-methyl aniline ( DMA: Di-Methyl Aniline) 0.5 ~ 3ppm.

Wherein the methyl methacrylate monomer is characterized by high coating film hardness, tensile strength, gloss, excellent solvent resistance, weather resistance when used as a raw material showing the main physical properties of the resin used as a non-slip binder, while low tensile rate and moisture There is a weak property, it is preferable to add within the range of 50 to 83% by weight adjusting the design formulation to compensate for the disadvantage by adding other monomers.

The butyl acrylate monomer is characterized by a higher elongation and flexibility, but relatively low tensile strength and hardness compared to the methyl methacrylate monomer, and has good adhesion, gloss, weather resistance, and solvent resistance. It is preferable to design an anti-slip binder while appropriately supplementing the advantages and disadvantages of the raw materials listed, and to add it within the range of 10 to 35% by weight.

The 2 ethyl hexyl acrylate monomer is very flexible and low gloss compared to the other raw materials, and the surface viscosity also occurs a little when polymerized and dried, it is used when the flexibility of the overall coating film is required when designing a resin by mixing a variety of raw materials, coating hardness And although the tensile strength is weak but serves to prevent cracking caused by physical impact is added within the range of 5-20% by weight.

The acrylic acid is flexible and functions as a plasticizer, adjusts tensile strength, tear strength, and the like, and plays an important role of the anti-slip binder in an appropriate composition with the monomer, and is preferably added within a range of 1 to 5% by weight.

The azobisisobutyronitrile is a raw material that serves as a reaction catalyst when synthesizing an anti-slip binder (resin), but a small amount is added as a raw material for controlling the rate, molecular weight, and viscosity of the polymerization reaction, but plays a large role in relation to the polymerization rate. Since it is necessary to precisely quantify the addition and in the present invention, it is preferable to add within 0.01 to 0.3% by weight.

The anti-slip agent is an acrylic copolymer resin and a plasticizer is used to improve the adhesion and workability of the road surface. As a thixotropic agent, a modified urea solution, silica sand, and a durable sieving pigment are used for wear over time. Improved.

In addition, by adding silica sand as an anti-slip aggregate, the anti-slip agent is manufactured to prevent slippage primarily by roughness (roughness) generated on the surface of the resin layer during coating, and by silica sand contained in the inside and the surface of the resin layer. It is not only excellent in slipping performance by preventing slipping in the second stage, but also prevents falling off or cracking on the road even after long-term use, and can express various colors using colored pigments.

In the test step, the composition mixing ratio was changed as shown in Table 1, and the asphalt road of 3m width and 0.6m width was coated with 1 ~ 10mm thickness, and after 3 ~ 18 months, the attachment state and the wear state were confirmed. Is shown in Table 2.

Composition content ratio table according to each example (unit: wt%) Composition  Example 1 Example 2 Example 3 Example 4 Example 5 Acrylic Copolymer 35 30 21 30 25 Colored pigments 3 3 3 2 2 Filler 16 19 19.5 10 17.3 Silicon dioxide 0.5 One 0.3 1.4 0.7 Antifoam 0.3 0.2 0.2 0.2 0.2 Plasticizer One 2 2 3 1.5 Denatured urea solution 2 0.5 One One 0.5 Polysiloxane 0.1 0.1 0.1 0.1 0.1 Silica sand 26.5 23 27.2 21 22 Steelmaking Slurry 15 20 25 30 30 Hardening accelerator 0.1 0.2 0.2 0.1 0.1 Hardener 0.5 1.0 0.5 1.2 0.6

As shown in Table 2, when used in the present invention, when the non-slip agent is installed on the road, it is excellent in wear resistance, thereby maintaining long-term anti-slip performance by roughness formed by thixotropy of paint and high-strength sieving pigment and silica sand. Not only that, but the construction is completed by applying the masking method to the applied area, it is faster to dry and easier to install than the existing anti-slip paint, and it prevents slipping primarily by silica sand, and the thixotropy of the anti-slip agent The anti-slip performance is excellent by preventing the sliding by the roughness formed by the second roughness.Since the silica sand impregnated inside is exposed even when the roughness formed on the slipper is worn out for a long time, the durability is excellent. Being able to have performance The.

Hereinafter, a process of forming grooving on the road surface using the anti-slip agent will be described in detail with reference to FIGS. 2 to 5.
