Description

MMA type anti-slip packaging composition incorporating PVA fibers, coating and construction method using the same {MMA type non-slip coating composition mixed with PVA fiber and Method of construction using the same}

The present invention relates to an MMA anti-slip packaging material composition containing PVA (polyvinyl alcohol) fibers, a coating film and a construction method using the same, and more particularly, to the surface of the structure of the MMA anti-slip packaging material containing PVA fibers In addition to, to protect the surface, to prevent slipping, MMA-based non-slip packaging material composition containing PVA fiber and construction method for crack prevention and crack repair of civil structures (steel, asphalt or concrete) using the same, It relates to a construction method for increasing the physical strength of the structure.

In general, anti-slip paving materials are applied to floors with low slip resistance (road surfaces, etc.), places with poor planar or vertical lines on roads, downhill roads, curved roads, etc. It is a traffic safety factor that secures the safety of pedestrians and drivers by preventing pedestrian accidents and shortening the braking distance of vehicles by increasing them, and inducing deceleration of vehicles to prevent traffic accidents.

To this end, in recent years, an adhesive is applied to the surface of the asphalt to prevent the vehicle from slipping from the asphalt, and then a non-slip agent made of rubber chips is placed on the surface of the asphalt to increase the coefficient of friction between the tire and the asphalt of the vehicle, Construction methods have been proposed to remove the water film phenomenon.

The above construction methods, the first method to be installed on the surface of the asphalt in the section in which the anti-slip agent will be installed, and the sliding in the installation groove while forming a groove in the surface of the asphalt in the section in which the anti-slip agent will be installed A second method for maintaining the same surface as the surface of the asphalt, and forming grooves on the surface of the asphalt while maintaining a constant distance therein to process grooves for improving the straightness of the vehicle and increasing frictional resistance. The third method and the like are used.

Both the first and second methods prevent the vehicle from slipping from the asphalt while generating a high friction force in the process of contacting the tire with the rough surface formed in the anti-slip agent. In the third method, 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 to prevent the vehicle from being pushed in one direction, thereby reducing the braking distance and speeding the vehicle. To prevent it. In addition, the third method prevents the vehicle from sliding off the asphalt by suppressing the water film phenomenon or freezing of the asphalt due to snow or rain as the asphalt water is drained through the groove.

In addition, the conventional non-slip facility is a form of finishing the surface by using a compaction roller of a certain weight after applying a resin to the road and spraying aggregate (steel slag), the appearance of the color is insufficient, the visibility is inferior, The dropping of aggregates impregnated in the resin due to the continuous impact caused by the driving vehicle proceeds, and the wear and slip resistance of the product is remarkably lowered. Sometimes it goes. In addition, the weather resistance is weak due to the rapid discoloration of the coating film occurs a phenomenon that the color of the product changes to white, thereby causing a sharp drop in visibility of the product. In addition, by using a thick aggregate in order to increase the sliding resistance, the thickness of the coating film is increased, causing vehicle vibration and deterioration of ride comfort when driving the car.

However, these conventional techniques are generally applied to the asphalt surface or concrete top, or after cutting the asphalt and / or concrete surface by a grooving method, a shot blasting method or a road surface planing method, such as the construction of the road surface by machine In addition to the deep cutting depth, these methods have problems such as damage to the road surface and defects in the road surface and material separation.

In the prior art, Korean Patent No. 10-0171675 discloses 50% or more of aggregate, which is steel slug or bauxite, 16-18% of resin ester, 10-13% of low density polyethylene, 2-4% of activated carbon, and rubber 2 ~. 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 on the pavement, and the non-slip pavement is applied to the road surface with a uniform thickness to perform flat work. After curing at room temperature for 10 to 15 minutes. Such a conventional non-slip pavement material is a form of the aggregate, which is a mineral bauxite, when the product is applied to the bottom settled to the floor by the load, the resin component is wrapped around the surface of the aggregate, so the slip resistance is relatively low, and over time When the surface is worn out, the settled aggregate is drawn to the resin surface and shows slip resistance, but the aggregate component is dropped by continuous impact and abrasion caused by vehicle traffic, and loses its function as an anti-slip material. Furthermore, it acts as a factor that brings about a decrease in reliability of the product as an anti-slip packaging material.

Therefore, it is possible to penetrate the concrete surface and improve the mechanical properties while overcoming the limitations of the existing coating film, and it is easy to work at the same time to solve the problems such as poor adhesion, water pocket, lifting, etc. that the existing coating film has, There is a continuing need for an anti-slip agent composition having excellent properties such as excellent durability, abrasion resistance, impact resistance, solvent resistance, chemical resistance, and stain resistance.

If the weight average molecular weight of the modified MMA is less than 50, there may be a problem that the ductility, which is an important property, is changed, and if the weight average molecular weight is more than 200, there may be a problem that the structure of the modified MMA is changed.
