MICTURE FOR PREVENTING WHEEL FROM SLIPPING ON THE STREET AND CONSTRUTION USING THE MIXTURE}

The present invention relates to an anti-slip construction method of a road and an anti-slip agent used therein. The anti-slip agent according to the present invention comprises a non-slip agent composed of a first agent, which is an anti-slip composition, and a second agent, which is a polymerization catalyst. ) Is used by mixing the second agent in the ratio of 1 (weight ratio). On the other hand, in winter, when the second agent is mixed at a ratio of 2 (weight ratio) to the main 100 (weight ratio) and uniformly applied to the road, the anti-slip construction can be completed within 5-30 minutes by chemical reaction. It would be.

In general, the road surface is slippery on downhill roads such as highways, national roads, and provincial roads, and the vehicle may leave the road or bend over by the speed of the vehicle. As non-slip facilities have been used a lot, and interest in safety accidents has increased, anti-slip pavements such as intersections, sharp curves and ramps, and non-slip facilities such as roads and parking lots in front of schools, pedestrian crossings, Other road accidents Non-slip facilities are installed and used in areas where traffic accidents occur frequently.

Composition for preventing slip of the general road is made to give a frictional resistance when driving the vehicle. An example of such a non-slip composition or a construction method thereof is the oldest method is to mix the stone powder, aggregate, rubber pieces, etc. in the synthetic resin and adhere to the road to prevent slipping. Similar patents are disclosed in Korean Patent Registration No. 0171675. The contents are mixed with thermoplastic resin low density polyethylene, activated carbon, ester rosin, rubber, stone powder, aggregate, and mixed with a powder at 200 ~ 250 ℃ in a melter, and then heated and melted. A method of constructing an anti-slip agent for road pavement, which can solve the peeling phenomenon in the conventional method using epoxy by directly applying to a road surface in a liquid state, has been introduced. It is produced in powder form by mixing low density polyethylene, activated carbon, hydrocarbon-based resin aggregating material and thermoplastic resin with main aggregate such as steelmaking slag or ceramic aggregate, and heating and melting at the temperature of 200-250 ℃ in the field. The easy way of working with one construction is introduced. According to the above method, the construction can be completed within a short time, but it is not economical because the non-slip agent including aggregate must be heated and melted at high temperature in the field, and the construction time is 4 ~% time because ester rosin and polyethylene are used. Because of this, there is a problem that road congestion is inevitable due to traffic control.

Korean Patent No. 297229 discloses a method of directly spraying an adhesive composition. Resin main composition and alkyl phenol, polyhydric polyamine and formaldehyde consisting of 10 to 30% by weight of modified epoxy resin obtained by reacting epichlorohydrin modified with fatty acid and bisphenol A and 70 to 90% by weight of liquid bisphenol A type epoxy resin An adhesive composition for road pavement consisting of a polymerization catalyst which is composed of a catalyst capable of carrying out a Mannich reaction mechanism is described. In addition, the step of spraying the adhesive composition on the road step of applying a non-slip aggregate on the road on which the adhesive composition is applied and the construction method of the non-slip road, characterized in that by curing the adhesive to attach the anti-skid aggregate to the road This is described. In this method, after applying the two-component resin composition to the road through a two-component spray device, a method of spraying steel-making slag on the road surface or attaching a non-slip plate manufactured to the second side is applied by the two-component spray device. . This patent method prevents slipping by applying the two-component resin composition to the road through a two-component spray device, and then spraying steelmaking slag on the road surface or attaching a pre-made anti-slip plate to apply a two-component spray device to prevent slipping. There is a hassle that the plate should be produced in advance, and there is a hassle of spraying the adhesive again by spraying the aggregate after spraying the adhesive on the road. In addition, the aggregate plate may initially maintain the tensile strength, but unlike the direct attachment to the road there is a problem that it is difficult to maintain the tensile strength over time.

Conventional anti-slip composition includes a thermosetting epoxy resin and there is a method of mixing in the thermosetting epoxy resin aggregate and the like in the field construction. In other words, select a non-slip facility to remove foreign substances or dust on asphalt or cement roads on slopes or curved roads, tape the area with tape, etc., and then put a primer, or in some cases, a thermosetting epoxy resin immediately. After applying, apply the sliding material of aggregate, steelmaking slug, red stone, etc., and press it with a roller to make it into a certain thickness and leave it for 3 ~ 4 hours to prevent the thermosetting epoxy resin from slipping. It penetrates into the aggregate and heats to harden. Such a non-slip construction takes a relatively long time of about 4 to 5 hours, causing a road congestion during construction, and has a problem that uniform non-slip construction is difficult during rapid construction. Since the thermosetting epoxy resin is used, there is a problem in that construction is impossible at dawn or at night when there is winter or moisture. In addition, it is difficult to maintain the non-slip facility in a certain thickness, there is a problem such as damage to the transportation load of the traveling truck.

On the other hand, there is a method of mixing the thermoplastic resin and the aggregate while heating (200 ~ 250 ℃) at the site of the non-slip facility as a method using a conventional thermoplastic resin and then fused to the road after the transfer from the melter to the construction machine. In this case, although the construction time is short within 2 hours, the aggregate distribution is biased, and the sliding phenomenon occurs on the surface of the plastic resin, and the construction cost is high. In addition, there is a problem in that it is difficult not only to repair the parts but also to be constructed with a uniform thickness and size.

There is a method of constructing an anti-slip facility by using a thermosetting resin. This method works by using a machine, so workability and weather resistance are good, but since the resin layer is very thick, it takes a long time to harden, so that the slag is impregnated into the resin layer. Since the anti-slip performance is reduced, and the effect of the speed bumps on the road, the riding comfort is not good, and if the driver is not found early, there is a problem that causes the risk of accident and damage to the vehicle.

In addition, Patent No. 0402098 discloses a packaging material and a method of manufacturing the same by using the waste tire pulverized product as an resistant component to improve elasticity and durability. When the waste tire pulverized product is used, the elasticity is improved, and the anti-slip performance cannot be played by the elasticity peculiar to the waste rubber.

The present invention has been made to solve the above problems, and the first agent containing the aggregate in the 2-COMP-COLD PLASTIC main body produced by the bulk polymerization of only the acrylic polymer monomer without using a solvent and It is an object of the present invention to provide an easy-to-use anti-slip agent which consists of a second agent which is a polymerization catalyst and only needs to mix and mix the first agent and the second agent before construction.
