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 pattern 11 and shadow 12, and sprinkle reflective glass beads and self-illuminating beads on the surface of 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 wear and t...

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 pattern 11 and shadow 12, and sprinkle reflective glass beads and self-illuminating beads on the surface of 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, specifica...

Abstract

The invention discloses a road sign for avoiding going in a direction not allowed by traffic regulations, and particularly relates to a pattern. The pattern comprises a body and a shadow correspondingto the body, wherein a three-dimensional picture formed by the body and the shadow can be observed when a human body is positioned in an inverse passage direction of a road where the pattern is positioned; the pattern of the body and the pattern of the shadow have a difference of 1-2 Munsell chromatic values; and the body has a self-illumination effect and can generate macroscopic luminance for 20min after the body receives light source irradiation. By use of a perspective principle, a simple pattern system is used for causing an illusion of a three-dimensional obstacle for a driver in a specific direction, no obvious significances are generated for drivers in other directions, a behavior of going in the direction not allowed by traffic regulations can be effectively prevented, and an effect on improving traffic safety is achieved.

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...
