MMA type non-slip coating composition mixed with PVA fiber and Method of construction using the same}

The present invention relates to an MMA-based anti-slip packaging composition incorporating PVA (polyvinyl alcohol) fibers, a coating film and a construction method using the same, and more particularly, to an MMA-based anti-slip packaging composition containing PVA fibers on the surface of a structure It is a construction method for preventing cracks and repairing cracks in an MMA-based anti-slip pavement composition mixed with PVA fiber and a civil engineering structure (steel, asphalt, or concrete) using the same, which protects the surface and prevents slipping. It relates to a construction method to increase the physical strength of the structure.

In general, anti-slip paving materials are installed on floors (road surfaces, etc.) with low sliding resistance, places with poor flat or longitudinal linearity on the road, downhill roads, and curved roads, and thus the coefficient of friction. It is a traffic safety factor that secures the safety of pedestrians and drivers, such as preventing pedestrian accidents and shortening the braking distance of vehicles by increasing the value, and preventing traffic accidents in advance by inducing reduced driving of vehicles.

To this end, in recent years, an adhesive is applied to the asphalt surface to prevent the vehicle from slipping from the asphalt, and then an anti-slip agent made of rubber chips is installed on the surface of the asphalt to increase the coefficient of friction between the tire of the vehicle and the asphalt, and to dry the asphalt surface. Construction methods to prevent water film by removing were suggested.

The above construction methods include a first method in which the anti-slip agent is installed on the surface of the asphalt in the section where the anti-slip agent is to be installed, and the slip is installed in the installation groove while forming a laying groove on the surface of the asphalt in the section in which the anti-skid agent is to be installed. The second method of keeping the inhibitor on the same surface as the asphalt surface, and forming grooves to improve the straightness of the vehicle and increase the frictional resistance by forming the intaglio of the surface while maintaining a certain interval in a dense state on the surface of the asphalt. The third method is being used.

Both the first and second methods prevent the vehicle from sliding from the asphalt while generating high frictional force while the rough surface formed on the anti-slip agent comes into contact with the tire. In addition, the third method prevents the vehicle from being pushed in one direction as the intaglio groove formed on the surface of the asphalt makes direct contact with the tire and the outer circumferential surface of the tire is pushed into the groove, and reduces the braking distance and speeding of the vehicle. To prevent. In addition, the third method prevents the vehicle from slipping from the asphalt by suppressing the water film phenomenon or freezing of the asphalt due to snow or rain as much as water is drained through the groove.

In addition, the conventional anti-slip facility is a type of finishing by compacting the surface using a compaction roller of a certain weight after applying resin on the road and spraying aggregate (reinforced slug), and the visibility is poor due to insufficient color expression. Due to the continuous impact of the driving vehicle, the aggregates impregnated in the resin are degraded, which significantly decreases the abrasion and slip resistance of the product, and the durability of the product is weak. It can also be done. In addition, due to poor weather resistance, the color of the coating film proceeds rapidly, resulting in a phenomenon in which the color of the product turns to white, resulting in a sharp decrease in the visibility of the product. In addition, by using a thick aggregate to increase slip resistance, the thickness of the coating film is increased, which causes vehicle vibration and ride comfort during operation of the vehicle.

However, such a conventional technique is generally applied to the asphalt surface or concrete upper part, or after cutting the asphalt and/or concrete surface by a grooving method, a shot blasting method, or a road surface grinding method, etc. Although applied, these methods have a problem that not only the depth of cut is deep, but also the road surface is damaged or defects in the road surface and material separation phenomenon occur.

Among the prior art, Korean Patent Registration No. 10-0171675 includes 50% or more of re-steel slug or bauxite aggregate, 16-18% resin ester, 10-13% low-density polyethylene, 2-4% activated carbon, and 2-4 rubber. 4% and 10-20% of the fillers of stone powder and silica are heated and melted at 210-250℃ to form a non-slip pavement material, and the non-slip pavement material is applied to the road surface in a uniform thickness to perform flat work. After that, it is cured at room temperature for 10 to 15 minutes. In such conventional anti-slip pavement materials for roads, when the product is applied, the aggregate component, which is a mineral bauxite, is settled to the floor by the load, and the resin component surrounds the surface of the aggregate. When the surface of the ground is worn, the settled aggregate is drawn to the resin surface and shows sliding resistance, but the aggregate component is eliminated due to continuous impact and abrasion due to vehicle traffic, resulting in loss of the function as an anti-slip material, causing a decline in the function of sliding resistance. Furthermore, it acts as a factor that leads to a decrease in the reliability of the product as an anti-slip packaging material.

Therefore, while overcoming the limitations of the existing coating film, it is possible to penetrate the concrete surface and improve mechanical properties, and it is easy to work while solving problems such as poor adhesion, water pocket, and lifting of the existing coating film. The need for an anti-slip composition having excellent properties such as excellent durability, abrasion resistance, impact resistance, solvent resistance, chemical resistance, and contamination resistance is continuously required.
