specific Embodiment approach 1

[0015] Specific implementation mode one: combine figure 1 Describe this embodiment, a wet-induced color-changing road traffic warning marking in this embodiment includes a transparent paint layer 1, a moisture-sensitive color-changing layer 2 and a warning color layer 4, a transparent paint layer 1, a moisture-sensitive color-changing layer 2, and a warning color layer Layer 4 is stacked sequentially from top to bottom.

[0016] In this embodiment, when the road surface is dry, the moisture-sensitive color-changing layer 2 is white, and the warning color layer 4 is covered by the white color of the moisture-sensitive color-changing layer 2; when the road surface is slippery, the moisture-sensitive color-changing layer 2 becomes transparent. At this time, the warning color layer 4 shows patterns or warning words for warning the driver that the road surface is slippery through the moisture-sensitive color-changing layer 2 and the transparent paint layer 1.

specific Embodiment approach 2

[0017] Specific implementation mode two: combination figure 1 Describe this embodiment, the thickness of the transparent paint layer 1 of the wet-induced color-changing road traffic warning marking described in this embodiment is 1mm-3mm, the thickness of the moisture-sensitive color-changing layer 2 is 1mm-3mm, and the thickness of the warning color layer 4 is 1mm-3mm. 1 mm to 3 mm. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0018] Specific implementation mode three: combination figure 1 Illustrate this embodiment, the specific steps of the wet-induced road traffic warning marking construction method described in a specific embodiment one described in this embodiment are as follows:

[0019] Step 1, paint the warning color paint on the road surface to form the warning color layer 4;

[0020] Step 2: Make the moisture-sensitive color-changing material into fine powder and prepare the moisture-sensitive color-changing paint with transparent paint and paint it on the upper surface of the warning color layer 4 to form the moisture-sensitive color-changing layer 2, and make the moisture-sensitive color-changing layer 2 completely cover the warning color layer 4;

[0021] Step 3: Apply a transparent paint on the upper surface of the moisture-sensitive color-changing layer 2 to form a transparent paint layer 1 , and make the transparent paint layer 1 completely cover the moisture-sensitive color-changin...

Abstract

A humidity sensitivity and temperature sensitivity color change road traffic warn marked line and a construction method thereof relate to a road traffic warn marked line and a construction method thereof, in particular to a humidity sensitivity and temperature sensitivity color change road traffic warn marked line and a construction method thereof. The invention aims to solve the problem that the existing marked line can only meet the traffic warn demands under the conventional road condition and has no function for differentiating the conventional road condition from a special road condition. The marked line comprises a transparent coating layer, a humidity sensitivity color change layer and a warn color layer which are sequentially arranged from top to bottom in an overlapping mode. The marked line also comprises a transparent coating layer and a temperature sensitivity layer which are sequentially arranged from top to bottom in an overlapping mode. The marked line is used for the field of road traffic.

Description

technical field [0001] The invention relates to a road traffic warning marking and a construction method thereof, in particular to a moisture-induced and temperature-induced discoloration road traffic warning marking and a construction method thereof, belonging to the field of road traffic. Background technique [0002] In wet and slippery rainy days or when it freezes in winter, traffic accidents are likely to occur due to the water film or ice film on the surface of the road, resulting in casualties and property losses. When the thickness of the water film on the road surface is 0.2mm, it is difficult for the driver to distinguish whether there is a water film on the road surface with the naked eye. At this time, the anti-skid ability of the road surface drops sharply, and the risk factor of driving increases. Appropriate warnings for the situation. In my country, there is no snow all year round in most parts of the south, but the temperature can drop to negative temperat...
