Problems solved by technology

With the help of a similar principle, Chinese patent CN 96123432.6 discloses a three-dimensional graphic traffic sign, which has a sign graphic, which has a plurality of parts in contact with each other on the road surface, and the brightness difference of each adjacent part is one or more levels. Purcell chromaticity value, so that the visible image looks like a three-dimensional image, however, the invention is not highly recognizable in rain, fog, and snow special environments, and it is mainly based on the principle of brightness, which will cause inability to detect when the ambient light is low Distinguish brightness difference

Embodiment 2

[0036]In another embodiment 2 of the present invention, the base coating system adopts a solvent-based coating system, and its specific composition and ingredients are as shown in Table 3, and the marking performance using the coating is as shown in Table 4, which meets the national standards and road safety standards. Use the base paint system to draw the pattern 11 and the shadow 12, and sprinkle reflective glass beads and self-luminous beads on the surface of the pattern 11, the amount of which is 0.3Kg / cm 2 , Rainy night luminescent glass beads using commercially available materials.

[0037] Self-luminous microbeads have a core-shell structure connected by a coupling agent, including a rare earth aluminate as the core and an organic coating as the shell. Under this structure, the organic coating can well realize the inner rare earth aluminum Compatibility between the acid salt and the base coating system, avoiding the drop of self-luminous microbeads caused by vehicle we...

Embodiment 3

[0045] In another embodiment 3 of the present invention, the base coating system adopts a solvent-based coating system, and its specific composition and ingredients are as shown in Table 5, and the marking performance using the coating is as shown in Table 6, which meets the national standards and road safety standards. Use the base paint system to draw the pattern 11 and the shadow 12, and sprinkle reflective glass beads and self-luminous beads on the surface of the pattern 11, the amount of which is 0.3Kg / cm 2 , Rainy night luminescent glass beads using commercially available materials.

[0046] Self-luminous microbeads have a core-shell structure connected by a coupling agent, including a rare earth aluminate as the core and an organic coating as the shell. Under this structure, the organic coating can well realize the inner rare earth aluminum Compatibility of acid salt and base paint system, avoiding the drop of self-luminous microbeads caused by vehicle wear and tear, s...

Abstract

The invention discloses a road anti-reverse sign, specifically a pattern, the pattern includes a body and a corresponding shadow, when the human body is located in the reverse direction of the road where the pattern is located, the body and the shadow can be observed The three-dimensional picture formed by the shadow; the body and the pattern of the shadow have a difference of 1-2 Munsell chromaticity values; the body has a self-illuminating effect, and can produce 20 minutes of brightness visible to the naked eye after being irradiated by a light source , the present invention uses the perspective principle and a simple pattern system to create the illusion of three-dimensional obstacles for drivers in a specific direction, but has no significant impact on drivers in other directions, effectively preventing retrograde behavior and improving traffic safety. .

Description

technical field [0001] The invention relates to the technical field of traffic signs, in particular to a road retrograde prevention sign. Background technique [0002] Traffic marking is a kind of road traffic signal, which is used to control and guide traffic. Its main functions include separating traffic, channeling traffic at level crossings, indicating and forecasting road conditions ahead, law enforcement and law-abiding basis. At present, the main traffic signs are flat symbols and graphics sprayed on the road surface, which are very easy to be ignored and cause insufficient reminders. In order to make up for the above defects, some roads are provided with raised deceleration strips to achieve forced deceleration, but these deceleration strips inevitably damage the running vehicle and cause uncomfortable bumpy feeling. [0003] 3D three-dimensional painting is a novel way of painting. Compared with ordinary painting, the most special thing is that its perspective prin...
