Problems solved by technology

However, due to the different shapes of marking lines required for different road sections, no matter which construction method is used, it is difficult to avoid the problem of drawing wrong marking lines. Once wrong marking lines are drawn, they can only be removed physically by a special line removing machine, which will damage the road surface. Make it need to be repaired before drawing the line, resulting in waste of resources and property loss
Not only that, the traditional marking lines are thermoplastic marking lines, which are brittle materials after molding, which cannot be prefabricated and cannot meet the requirements of rapid traffic opening
Although the traditional marking tape is simple and convenient to use, due to poor performance, it will be damaged in a short period of time and cannot be used for a long time
The recessed marking road surface cannot achieve convenient results because it needs to dig a hole in the road in advance, and once the position is wrong, it still needs a lot of repair work

Abstract

The invention belongs to the technical field of traffic facilities, and particularly relates to a carpet type elastic function marker and a preparation method thereof. The function marker comprises a marker coating and 1-2 parts of bottom films, wherein the maker coating comprises, by weight, 10-18 parts of film materials, 50-70 parts of fillers, 10-30 parts of pigments, 1-10 parts of photocatalytic materials, 1-5 parts of blending agents, 1-5 parts of supplements, 1-5 parts of coupling agents, 1-5 parts of leveling agents and 1-5 parts of plasticizers. Compared with the prior art, the carpet type elastic function marker and the preparation method thereof are convenient in operation and can be used for selecting a road marker position, the marker is adhered to a pavement and compacted by rolling equipment after determining the position, traffic can be opened immediately, and the shortcoming of repeated line drawing due to traditional marker spraying errors is overcome.

Description

technical field [0001] The invention belongs to the technical field of transportation facilities, and in particular relates to a carpet type elastic functional marking and a preparation method thereof. Background technique [0002] Pavement markings are an important part of highway construction and one of the important traffic engineering facilities to ensure road safety. Usually road markings are composed of various lines, arrows, characters, elevation marks, raised road signs and contour marks drawn on the road surface. The construction of traditional markings is divided into hot-melt type and solvent-type. Hot-melt markings are widely used in areas with heavy traffic such as expressways, national roads, and provincial roads due to their superior performance. However, due to the different shapes of marking lines required for different road sections, no matter which construction method is used, it is difficult to avoid the problem of drawing wrong marking lines. Once wrong...
