Paint manufacturers selling road markings at special prices for export worldwide

Introduction to the special sale and export use of paint manufacturers for road markings and road signs

Hot melt reflective marking coating is mainly used on highways and expressways of grade 2 and above. The thickness of the marking coating made by this coating is (1.0-2.5) mm, and reflective glass beads are mixed in the coating. During the marking construction, reflective glass beads are sprinkled on the surface. This type of marking has good nighttime reflective performance and a long service life. It is estimated that the demand for various road marking coatings depends on the quality of the coating itself, and can generally last for (2-3) years, depending on the traffic flow of the large highway construction. The construction of hot melt coatings requires special heating equipment. When recoating old markings, the thicker old coating must be removed before application.

Construction method

Hot melt marking paint is a solid powder at room temperature. During construction, the paint is put into a melting kettle, and the temperature inside the kettle is controlled between 180 ℃ and 210 ℃. While melting, it is stirred. After melting into a molten flow state, it is placed into the insulation melting hopper of the marking truck. The melted coating is then introduced back into the marking bucket and insulated to keep the material in a molten state. Before marking the line, a pre marking machine is used to mark the position, and a primer machine is applied to the designated coating position according to the design drawing. After the coating agent is completely dry, the marking paint can be applied. When starting to draw lines, the marking bucket should be placed on the road surface. Due to the certain gap between the marking bucket and the ground, a neat marking line should be scraped and wiped out by the automatic flow when the marking car is traveling. The glass bead spreader can automatically and evenly spread a layer of reflective glass beads on the marking line.

Advantages Introduction

Hot melt road marking coatings utilize the thermoplasticity of synthetic resins to give them quick drying properties, and use the hot melt properties of synthetic resins to firmly bond the markings to the road surface. Hot melt reflective road marking coatings are generally composed of thermoplastic resins, pigments, reflective materials, and other additives. Hot melt coatings are in powder form at room temperature. There are no solvent volatile components in the ingredients. Heating during construction causes it to melt, and then specialized equipment is used to apply it onto the ground, relying on physical condensation to solidify into a film. For hot-melt road coatings, their flowability is a very important technical indicator during the construction process.

introduction

Road marking paint is a coating applied on roads to mark road markings. Road marking paint is a safety sign and a “language” in highway traffic. Road markings are an important component of transportation infrastructure. Clear and complete road markings can provide drivers and pedestrians with good conditioned reflexes, effectively reducing accidents and improving driving efficiency. A statistic shows that the correlation probability between road markings and accidents is 70%, which can improve transportation efficiency by 30%. The increasing traffic volume on highways and the gradual increase in driving speed have raised higher requirements for the development and supporting, safe, economical, durable, and aesthetically pleasing performance of traffic safety facilities., Its liquidity is a very important technical indicator during the construction process.

advantage

Strong adhesion
Road marking paint should have strong adhesion to the ground in order to fully ensure the integrity and clarity of the markings. However, the shorter the drying time of general coatings, the worse their adhesion, so this constitutes a contradiction. One of the key technologies in the road coating industry is how to solve this problem first.
Wear resistant and have a long service life
Good road marking coatings should have a long service life, so as to ensure that the markings remain intact and clear for a long time, reduce the waste of manpower and material resources caused by repeated construction, and minimize obstacles and impacts on normal traffic.
Night reflection performance
Modern transportation not only requires daytime effects, but also emphasizes nighttime effects. Night reflective markings can greatly improve the safety of nighttime driving and also enhance the efficiency of nighttime driving. The more developed countries in the world pay attention to this, the higher the degree of road night lighting.
Dry quickly during construction
The environment in which road marking paint is applied has an uninterrupted traffic volume (even at night, there is a certain amount of traffic flow). Therefore, it is required that road coatings dry as quickly as possible. Depending on the type of coating, it is generally required to dry and open to traffic within 3-15 minutes. For general coatings, this requirement is almost too demanding, but it is a prerequisite for measuring whether a product can become a good road coating.
Good weather resistance and water resistance
Require the paint to maintain its freshness for a long time and have a slow natural aging process.
Economic viability
It is required that the coating cost be low and the selling price be cheap.
Green and environmentally friendly
In the research, production, and use of actual coatings, we can only meet the above requirements as much as possible, but it is also impossible to fully meet all of the above requirements at the same time. We can only focus on certain aspects.

Superior usage effect
(1) The film layer has fast drying properties. After painting, it can dry and open to traffic within 1-3 minutes, and even construction can be carried out without blocking traffic.
(2) Good usage effect. The coating lines of hot melt paint are complete and clear, with distinct edges and corners, high brightness, and a three-dimensional effect.
(3) Excellent wear resistance. The coating of this paint is durable and the service life of the markings can reach 2 years.
(4) Reflection at night. Due to the addition of glass reflective materials in hot-melt coatings, glass microspheres can be dispersed on the coating surface during construction, resulting in better reflective effects, reduced traffic accidents, and meeting the requirements of modern transportation facilities.
