Abstract

PROBLEM TO BE SOLVED: To improve workability and secure durability of visible effects by forming a plurality of protruded rib lines on traffic sign lines on a roadface and specifying the pitch of the protruded ribs in the arrangement and making constant the distance between respective arrangements. SOLUTION: The longitudinal direction of protruded ribs 2 is made to be orthogonal to the longitudinal direction of a traffic line 1 and the distance between two protruded ribs 2 of the same pair is set at 20-100 mm and the distance between the respective arrangements is set at 200-1,000 mm. Well-known traffic sign materials for melting such as caking resin, plasticizer, pigment, filler, glass beads, reflective materials, thiscotropic agent such as wax are used as the traffic sign materials for the road face. And traffic sign lines 1 having bar-form protruded ribs 2 are formed and arranged in pairs. And hence, the traffic sign lines are excellent in the workability of the roadface traffic lines such as pedestrian crossing, medial strip, outside lane, letters, signs, etc., and visibility during driving. In this way, the visibility can be retained for a long time and secured even in rainy days and at night.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a convex rib type road marking line used as a marking line on a road such as a lane boundary line, a lane center line, a lane outside line, a pedestrian crossing, characters and symbols, and a method of manufacturing the same. .

[0002]

2. Description of the Related Art Conventionally, in marking roads such as lane boundary lines, lane center lines, lane outer lines, pedestrian crossings, characters, and symbols, hemispheres are used as marking lines having high visibility even in rainy weather (at night). There is known a marking line in which a convex rib such as a trapezoidal shape is provided, and glass beads are further scattered and fixed thereon. Such a marking line is constructed by a single coating using a road marking material for melting and a two-component reaction type road marking material, and also by forming a convex rib after forming a planar coating film. . At this time, staggered, parallel, slant type, etc. are adopted as the arrangement of the convex ribs, and even if the shape, length, width, etc. are different,
The ribs are formed at intervals for each convex rib. The convex rib coating is not covered by the rainwater film, and the glass beads on the surface retroreflect the headlight light of the automobile, thereby improving the visibility of the marking line to the driver.

However, when the convex ribs are formed of the road marking material for melting, since the convex ribs are formed one by one, the glass beads scattered and fixed on the surface thereof are reflected on the reflection surface. There is a problem that the vehicle is separated from a certain side surface due to the impact of the vehicle traveling (upward traveling, downward traveling), and the visual recognition effect is reduced. In addition, although the two-component reactive road marking material has few problems like the road marking material for melting, it has low workability such as a long drying time during construction and low viscosity and low rib height. In some cases, the height cannot be increased, and in this case, there is a problem that the perception of the vehicle during traveling is poor.

[0004]

The invention according to claims 1 to 4 solves the above-mentioned problems, and provides a method of manufacturing a marking line which has good workability and good visibility. Is what you do. The invention described in claim 5 solves the above-mentioned problem, and provides a sign line with good workability and good persistence of the visual effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing a part of the marking line in the present invention. FIG. 2 is a sectional view taken along the line aa. The marking line 1 is, for example, a center line of a road. The marking line 1 is formed with a pair of two square-shaped convex ribs 2. The longitudinal direction of the convex rib is preferably perpendicular to the longitudinal direction of the marking line. The interval between two sets of the same convex ribs is preferably 20 to 100 mm, more preferably 30 to 70 mm. If this interval is too large, the glass beads on the rib surface tend to separate easily due to the running of the vehicle,
Conversely, if the interval is too small, the visibility tends to decrease. Further, the interval between each pair of convex ribs is preferably 200 to 1000 mm, and 300 to 700 mm.
mm is more preferred. If this interval is too small, the visibility of the vehicle tends to decrease over time due to the running of the vehicle. Conversely, if this interval is too large, the visibility of the day and the sensitivity during traveling of the vehicle tend to deteriorate. The number of the above-mentioned convex ribs is not limited to two, but may be three or more.

Although the size of the convex rib depends on the size of the marking line, the length of the convex rib in the longitudinal direction is 80 to 80 times the width of the marking line.
Preferably it is 90%. Specifically, 100 to 20
The length is preferably 0 mm, and may be longer. However, when the length is longer than that, it is preferable to divide the convex ribs and arrange the convex ribs side by side in the longitudinal direction. The length of the short side of the convex rib is preferably 15 to 50 mm.
The height of the convex rib is preferably 3 to 9 mm. The shape of the convex rib is not only the above-mentioned spiral shape, but also a shape obtained by cutting a cylinder in a plane in the axial direction (a shape like a bat), a truncated ellipsoid (a shape obtained by cutting an ellipsoid in a plane). and so on.

As the road marking material used in the present invention, conventionally known road marking materials for melting can be used. For example, in the present invention, there are a binder such as a binder resin, a plasticizer, a pigment, a filler, a glass bead, a reflective material such as a scaled glass crushed powder, and a thixotropic agent such as a wax. Examples of the binder resin include raw rosin, maleated rosin, maleated rosin ester resin, petroleum resin, hydrogenated rosin, hydrogenated petroleum resin, terpene resin, polypropylene, ethylene vinyl acetate copolymer resin, ethylene ethyl acrylate copolymer resin, etc. 1
It is used alone or in combination of two or more. Examples of the plasticizer include vegetable oil, vegetable oil-modified alkyd resin, mineral oil, epoxidized oil, and liquid synthetic rubbers. Examples of fillers include those used as aggregates and building materials such as calcium carbonate, silica sand, talc, cold water stone, alumina powder, and white Morundum. The white pigment of the coloring pigment includes titanium dioxide, zinc white, lithopone, lead white, and the like, and the yellow pigment includes yellow lead, heat-resistant yellow lead, organic yellow pigment, and the like. As a reflective material,
Scaly crushed glass powder, glass beads or the like can be used in combination. The glass beads preferably have a particle size in the range of 105 to 840 μm.

The composition of the road marking material for fusing includes:
100 to 650 parts by weight of binder resin, 100 to 650 of reflective material
It is preferable to use 10 parts to 22 parts by weight of a plasticizer, 0 to 60 parts by weight of a pigment, 0 to 300 parts by weight of a filler such as an aggregate and a filler, and 0 to 30 parts by weight of a thixotropic agent. In addition, if necessary, additives such as an anti-settling agent, an ultraviolet absorber, and a viscosity reducing agent may be added. The melting viscosity of the road marking material for melting is preferably 5,000 to 150,000 centipoise at 150 to 200 ° C.
