Road traffic marking material and preparation method thereof

Abstract

The invention provides a road traffic marking material and a preparation method thereof, and is characterized in that the road traffic marking material comprises the following components in parts by weight: 3-8 parts of cementing material, 20-25 parts of coarse aggregate, 20-25 parts of fine aggregate, 6-8 parts of filler, 1-2 parts of curing agent and 1-2 parts of anti-aging agent. The preparation method comprises the following steps: (1) weighing all the components in parts by weight for later use; (2) mixing and stirring the cementing material and a curing agent in proportion to prepare a cementing agent; and (3) uniformly mixing the coarse aggregate, the fine aggregate and the titanium dioxide, injecting the cementing agent, continuously stirring until the mixture is uniform, sequentially adding the reflective powder and the anti-aging agent, and quickly stirring to obtain the road traffic marking material. The road traffic marking material prepared by the invention adopts a concrete form and has a skeleton structure, the pavement performance of the road traffic marking material is equivalent to that of a pavement wearing layer, the durability and functionality of a marking arekept for a long time, and the service life of the marking is prolonged.

Description

technical field [0001] The invention belongs to the field of road traffic markings, and in particular relates to a road traffic marking material and a preparation method thereof. Background technique [0002] Road traffic markings, as a means of traffic safety to restrict drivers' driving behavior, not only ensure driving safety and smooth traffic, but also provide reliable driving guidance for drivers. However, at present, a large number of road markings are in low-performance service state, and problems such as peeling, cracks, and peeling will occur in the early stage of service, and the integrity of the marking itself cannot be continuously guaranteed, and the durability is seriously insufficient. On the other hand, under the natural environment erosion and vehicle rolling and friction, the marking line wears seriously, resulting in a reduction in the general visibility of the marking line. [0003] Therefore, the longest service life of various types of road markings i...

Problems solved by technology

In order to improve the use level of my country's road marking paint, Chinese scholars have done a lot of research, such as "a kind of self-luminous road marking paint and its application" whose publication number is CN105860738D, and "a kind of high coloring degree paint" whose publication number is CN106147324. Luminescent reflective road marking paint and its preparation method", the publication number is CN109233530A "super wear-resistant water-based road marking paint and its preparation method", the publication number is CN107459907 "continuous self-illumination at night, strong reflective road marking and its production method", the publication number is CN205088588 "water-based self-illuminating reflective road markings", etc., but only improve a certain performance or several performances of the markings, and all fail to coordinate with the attenuation of road surface performance. To harmonize with the road performance of the road itself, so that the occurrence of road surface diseases affects the use effect of road markings

At the same time, the existing technologies are all layered "painted" or "sticked" on the road surface in the form of adhesion and paste. The biggest drawback of layered spraying is that the adhesion between the marking primer layer and the road surface is poor, which can lead to Problems such as road markings falling off under rain erosion

Overall, there are no substantial breakthroughs in material composition and structural modes
