Description

Non-slip composition {Non-slip composition}

The present invention relates to an anti-slip composition. In more detail, it is possible to improve the anti-slip properties, and furthermore, it relates to a non-slip composition capable of shortening the construction time, as well as possible construction in a relatively low temperature range.

In general, on a paved road, there are various markings such as lanes, shoulder marking lines, speed bump marking lines, and crosswalk marking lines on the road surface to indicate the direction of the vehicle or pedestrian. These markings are generally constructed using paint compositions.

However, most of these paint compositions form a smooth coating film on the surface, so when snow or rain falls due to inclement weather, they not only provide the cause of an accident due to slipping, but also have low visibility, require heavy attention from drivers or pedestrians, and cause accidents.

Methods of preventing the vehicle from slipping from the road surface include a method of increasing the coefficient of friction between the tire and the road surface by wrapping an anti-skid plate on the road surface, and a method of removing moisture from the road surface by designing so that moisture from the road surface is well drained.

In general, a method of constructing an anti-skid plate on asphalt or cement using a non-slip material is mainly used when constructing a road. For example, an anti-skid plate is installed at a certain distance in a downhill lane or a curve of a road, so that the driver who passes through the area where the anti-skid plate is installed is not only guided to drive down the road, but also prevents the vehicle from slipping or losing balance due to speed. Traffic accidents are prevented in advance.

In addition, a non-slip construction method is applied to general paved roads to reduce traffic accidents caused by slippery road surfaces. It is proposed to use steel-making slag or ceramic aggregate as a non-slip aggregate, and to directly construct it on the road surface using a fluorine-epoxy modified resin, or in some cases, an epoxy adhesive. That is, an adhesive is applied to the road surface, aggregates are sprinkled thereon, and then a non-slip layer chopped with a roller is formed on the road surface.

However, such a construction method has a problem that it is very difficult to work in winter or at night when there is a lot of humidity or dew due to the influence of temperature or climate. In addition, even if construction is possible, the adhesive strength of the road surface according to temperature changes is greatly weakened, so that the coating film is easily peeled off and peeled off. In addition, even if the temperature and the climate are adjusted, the construction time is very long, limiting vehicle traffic for a long time, causing traffic jams, and resulting in a large burden of logistics costs.
