1. Types of color pavement
It can be said that no matter how the functions or functions of the color anti -slip road surface are defined regardless of how each management unit or usage unit is defined, there are nothing more than several aspects, such as bus lanes, bicycle lanes, and scenic highways are the concrete of these functions.In actual applications, it is basically a few materials that can be constructed on the market.
1. MMA dual -component color anti -slip road surface
2, epoxy color anti -slip road surface
3. Polyurethane color non -slip road surface
4. Floor lacquer pavement (mainly epoxy materials)
5. Color asphalt pavement
6. Color micro -tables pavement
7, hot -melt color anti -slip road surface
Second, their basic characteristics
2.1mma dual -component color anti -slip road surface
MMA dual -component color non -slip road surface is coatings made of methyl acrylic activated resin as the basic material and matched with a custard. Now there are MMA dual -component coatings produced by imported resin and domestic resin production.At about 20%.Ceramic particles with different colors of color during construction make color non -slip roads.The specific construction process is:
Bottom material+non -slip bone material+cover material
Features: (1) No VOC emissions, more environmentally friendly and energy -saving.
(2) Good pressure resistance, wear resistance, and adhesion.
(3) High -aging and low temperature resistance.
(4) Good weather resistance, oil tolerance, acid and alkali.
(5) No cracks (the material made of domestic resin does not meet the large molecular chain structure after the imported resin reaction, and the coating strength is much different).
(6) The construction temperature is less affected by temperature, and the response time is generally about 1 hour. It can be constructed normally in winter.
2.2 Epoxy color non -slip road surface
It is a coatings made of epoxy resin as the basic material and a paint -filled. Ceramic particles of different colors are made of burned different colors during construction to make color anti -slip road marking lines.The specific construction process is:
Bottom material+non -slip bone aggregate
Due to the characteristics of epoxy resin itself, epoxy color coatings cannot be covered with surface construction. If it is not necessary to cover the surface, it is better to use solvent paint construction.Essence
Advantages: Cheap price. Now the most color pavement materials are used on domestic roads and urban roads, which are used by many construction units.
Disadvantages: (1) Cracks, cracks may occur shortly after construction, especially on new asphalt roads.This is mainly because the newly built asphalt pavement has not yet stabilized; asphalt pavement is a flexible road, and the epoxy resin reacts is a rigid structure layer. The two structural layers are very inconsistent.Fragmentation causes cracks in color coatings.At the same time, if the asphalt surface layer may also occur slightly when it is not stable.This situation basically does not exist on the cement road surface, and the effect on the old asphalt road is better.In recent years, manufacturers have promoted to eliminate the rigid stress of epoxy resin through modification, but in actual applications, it has gradually leaked problems over time.
(2) Trimming: Poor epoxy resin has a poor weather resistance, and there is a yellow change reaction. Over time, whether it is adjusted to red or other colors at the beginning, it will change yellow after a while. This problem is a common problem.Therefore, epoxy color coatings cannot directly leak in the sun.
(3) Flutization: There is also a defect in the characteristics of epoxy resin itself. It is poorly resistant. When the time is slightly slightly, the phenomenon will occur, but it generally occurs more serious after 1.5 years.
(4) A long curing time: CITC time is related to temperature. When the summer temperature is higher than 30 degrees, it is generally about 2 hours, and the temperature may reach more than 20 hours when the temperature is lower than 10 degrees.
2.3 Polyurethane color non -slip road surface
Polyurethane color non -slip road surface is a coating made of polyurethane resin as the main basic material and matched with fillers. Ceramic particles with different colors of color during construction are made into color anti -slip road marks.It and epoxy resin belong to the category of chronic color -colored anti -slip coatings, and the general response time is more than 4 hours.Polyurethane resin has free isocyanate molecules in the material before the reaction. This molecule is a toxic material and has a great harm to personnel.It is more environmentally friendly material.The specific construction process is:
The bottom coating material+non -slip aggregate, generally no one uses the cover of the cover.
Features: The price is large, and polyurethane materials are different in China. If it is basically a pure resin material, the paint viscosity is large, and the cost of the material will be higher.The diluent is similar to the epoxy color coatings. The cost of coatings can be greatly reduced to about 20,000 yuan. Therefore, the price quotation on the market is relatively chaotic. The construction price can be available from 100 yuan to 200 yuan, which makes people confused.
2.4 Color asphalt pavement
The color asphalt pavement is a kind of asphalt pavement construction. He uses asphalt mixing buildings to add various thick details and pigments to the colorless asphalt. The mix of the mixing building produces asphalt concrete and then transports it to the proposed construction road.Put on the pavement, the rolling of the road press is completed. The overall construction process process is asphalt pavement construction process process. Generally, it is used in the highway mileage and a large amount of engineering. The thickness of the pavement has reached more than 3 cm., Wuhan and other cities have adopted some sections of construction, but after application, the effect is not good, and it has not been promoted well.
