Description

Wear-resistant wet-feel road marking paint

Technical Field

The invention relates to the field of traffic markings, in particular to wear-resistant and wet-feel road marking paint.

Background

Road marking is one of the important safety facilities of road, has played instruction and warning effect to the road user, and the most road marking type of using in each country at present mainly has: normal temperature solvent type, heating solvent type, hot melt vibration type, water-based road marking, anti-skid road marking and the like. From the characteristics and the application condition of all kinds of marked lines, most marked lines do not have good wear resistance, and most importantly, the marked lines cannot play a good warning effect on drivers under the weather conditions of rain, snow and haze, and the driving safety cannot be guaranteed. Therefore, the method aims at areas with more days of rain, snow and haze: the road surface marking has poor durability, low visibility when a driver drives a vehicle, wet and smooth road surface and difficulty in being perceived under the condition, so that the problem of frequent traffic accidents is caused, and the novel wear-resistant wet-feeling marking paint is provided.

Disclosure of Invention

The invention aims to: aiming at the defects in the prior art, the road marking which has good wear resistance and can show good warning effect under the weather conditions of rain, snow, haze and the like is designed.

The invention designs a road marking capable of displaying a good warning effect under weather conditions such as rain, snow, haze and the like, which is designed according to the following design principle: the ground marked line is subjected to double-layer paving treatment, the marked line of the base layer is a yellow acrylic resin material, has a carbon double structure, has strong durability and wear resistance, does not fade, is convenient to clean, can reduce the radiant heat of the asphalt pavement, and is an environment-friendly material; and the surface course marking is the wet coating of feeling of white that covers the effect well under the dry condition, and when rainy day or road surface humidity are great, the road marking can show the colour of basic unit, shows the white of surface course again after the road surface is dry. The surface layer of the wet-sensitive marking line is composed of raw materials such as a wet-sensitive color-changing body, a sensitizing agent, a toner, a film-forming agent and the like, wherein the raw materials of the color-changing body are cobalt chloride and hexamethylenetetramine (C)₆H₁₂N₄) The color of the material can change with the change of humidity in the atmosphere, and the sensitizing agent is urea (CN)₆ON₂) The toner is chlorinated phthalocyanine and the film-forming agent is butyl acrylate. The proportion of each component is 15-20 parts of cobalt chloride, 15-20 parts of hexamethylenetetramine, 1-3 parts of urea, 5-10 parts of chlorinated phthalocyanine and 55-60 parts of butyl acrylate. When the wet color-changing coating is used as a surface layer material of a wet marking, the covering effect and the color-changing effect when the coating and printing times are 3 times are both optimal; the recommended total thickness of the marked line is about 0.7mm to 2mm, and the marked line with the thickness of 1mm has the highest dynamic stability of 4117.647 times/mm. Through a dynamic stability simulation real vehicle test, the appearance of the marking line is kept unchanged, the conditions of falling and abrasion are avoided, and good abrasion resistance is shown.

① compared with the basic dynamic stability of the rut plate, the dynamic stability is improved by 91.7%, the marking has good anti-rut performance and wear resistance, 14.1% of cost can be saved by adopting the wear-resistant wet-feeling marking, the required construction environment is loose, the working site area is small, the construction can be carried out at-20 to 40 degrees, the traffic can be opened after about half hour after the construction, the laying efficiency is high, the traffic delay caused by the construction is reduced, and the influence on the road traffic flow is small, therefore, compared with the common marking, the novel wear-resistant wet-feeling marking embodies a great economic advantage, ② viewed from the social benefit aspect, the use of the wear-resistant wet-feeling marking as an environment-friendly material has very important significance on prolonging the service life of the marking, reducing the road noise and reducing the environmental pollution, and can show good driving warning effect under the weather conditions of rain, snow, fog and the like, and the safety of drivers and the violation of driving are reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments.

Embodiment 1, this embodiment discloses a wet-feel wear-resistant road marking paint, which comprises the following components by weight: 18 parts of cobalt chloride, 17 parts of hexamethylenetetramine, 2 parts of urea, 8 parts of chlorinated phthalocyanine and 55 parts of butyl acrylate in the surface layer; the acrylic resin of the base layer is proper.

1. Construction process of wet-sensing marking line

Mainly comprises four steps: preparation work such as pavement cleaning (pavement protection and priming), preparation and paving of acrylic resin materials (adding coarse sand, adding an auxiliary agent, a reinforcing agent and blade coating operation in raw materials), coating and printing of wet-feel paint and open traffic (tearing of adhesive tapes). The protection of the pavement is to cover the area except the marked line with an adhesive tape so as to prevent the marked line material from sputtering to the normal pavement, and the priming paint is used for enhancing the bonding force between the marked line and the pavement. The formulation of the materials used in the stage of preparing the acrylic resin is shown in the following table.

2. Points of construction attention

(1) The surface of the rut plate is not cleaned completely in the test process, so that the marked line falls off, and therefore, in the road surface cleaning stage, the road surface is ensured to be dry, clean, free of oil stains, foreign matters and dust, and otherwise, the construction quality is poor.

(2) In order to ensure that other road surfaces except the marked line region are not polluted by the coating, the road surface of the construction road section needs to be locally protected, and the adhesive tape is pasted on the region except the marked line region.

(3) When the primer is coated on the cement pavement, the primer is uniformly coated, so that the acrylic resin material is tightly adhered to the pavement. The concrete pavement and the asphalt pavement do not need to be brushed with primer, and can be well bonded with the acrylic resin material under the condition of clean pavement.

(4) After the primer is dried, adding the aggregate, the auxiliary agent and the curing agent according to the proportion, uniformly stirring, then carrying out blade coating operation, selecting the particle size of the coarse sand according to different thicknesses, and uniformly stirring before adding the coarse sand. Although the amount of the auxiliary agent and the catalyst is increased to accelerate the curing of the resin material, the mixture ratio is not more than the recommended value for ensuring the safety of constructors because the mixture releases a large amount of heat during the reaction.

(5) After finishing the scratch coating operation of the marked line, the adhesive tape needs to be removed after the marked line is completely dried, and the traffic is opened, so that the quality problem can be caused when the traffic is opened under the condition that the marked line is not dried.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
