Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a colored water-permeable asphalt binder mixed at room temperature and a preparation method thereof. Background Art

[0002] Colored permeable asphalt binder is a pavement material that is both decorative and functional. This material not only provides a rich selection of colors, but also allows for efficient water penetration, which helps manage urban rainwater. Colored permeable asphalt binder is a pavement decoration material made from high molecular polymers. Through a special production process, raw materials such as resins, high molecular polymers, filler oils, and admixtures are mixed to form a binder with a specific color and permeability. The preparation of colored permeable asphalt involves placing a certain proportion of raw materials into a reactor, stirring and reacting them at a certain temperature and pressure to produce a light-colored binder. , and then add different color powders as needed to make colored permeable asphalt of different colors, which is mainly used in slow-moving systems such as greenways, bicycle lanes, and garden landscape roads. It is also suitable for parking lots, city squares and other places. Due to its good permeability and decorative effects, colored permeable asphalt plays an increasingly important role in modern urban construction. Colored permeable asphalt binder has great application potential in modern urban construction with its unique permeability, high bearing capacity and rich colors. With the continuous advancement of technology and the enhancement of environmental awareness, this material is expected to play a more important role in future road construction.

[0003] For example, the patent document with the announcement number CN 114773781 B discloses a cold-mixed colored permeable asphalt binder and a preparation method thereof, wherein the cold-mixed colored permeable asphalt binder is a mixture of components A and B; the component A is composed of epoxy resin, plasticizer, allyl glycidyl ether, pigment, heavy calcium and talcum powder; the component B is an alicyclic amine curing agent. The epoxy resin in the component A is selected from bisphenol A type epoxy resin, which has very stable physical and chemical properties. Its performance is still stable at a high temperature of 200°C, and can significantly enhance the tolerance of concrete to temperature changes. The use of plasticizers can enhance the toughness of concrete, making it less likely to break under pressure, while heavy calcium can reinforce the concrete. The binder obtained by the present invention has excellent durability and rutting resistance while retaining the advantage of high permeability.

[0004] With the advancement of science and technology and the development of society, people have higher and higher requirements for travel systems, and are paying more and more attention to the cycle of the ecological environment. The construction of sponge city systems has come into being. Permeable paving materials, as the most common link in the sponge city construction system, can not only replenish the internal circulation of groundwater resources in a timely manner, but also improve the functionality of people's travel system pavement. At present, the most common permeable paving materials are permeable cement concrete and permeable asphalt concrete. Permeable cement concrete has been widely used in recent years because of its easy availability of raw materials, low construction cost and high durability of the produced permeable concrete. However, due to its own size, Due to the material properties and structure, the permeable concrete produced has the disadvantages of easy breakage, cracking, and easy clogging of gaps, which leads to poor or even disappearance of permeability. However, the permeable asphalt concrete has high permeability, but poor adhesion, poor anti-rutting performance, high production energy consumption, and construction is subject to large site limitations. In summary, in order to solve a series of problems of the existing permeable asphalt, the market urgently needs to find a colored permeable asphalt binder mixed at room temperature with better performance, simpler construction, and lower energy consumption, which cannot meet daily use needs. Therefore, it is urgent to design a colored permeable asphalt binder mixed at room temperature and a preparation method thereof to solve the above problems. Summary of the invention

With the progress of science and technology and the development of society, people have higher and higher requirements for travel systems, and are more and more concerned about the circulation of the ecological environment. The construction of sponge city system has come into being. Permeable paving materials, as the most common link in the sponge city construction system, can not only replenish the internal circulation of groundwater resources in time, but also improve the functionality of the road surface of people's travel system. At present, the most common permeable paving materials are permeable cement concrete and permeable asphalt concrete. Permeable cement concrete has two kinds of permeable paving materials because the raw materials are easy to obtain. The permeable concrete produced has low construction cost and high durability, so it has been widely used in recent years. However, due to its own material characteristics and structure, the permeable concrete produced has the disadvantages of easy breakage, cracking, and easy clogging of gaps, resulting in poor or even disappearance of permeability. Although permeable asphalt concrete has high permeability, it has poor adhesion, poor anti-rutting performance, high production energy consumption, and construction is subject to large site limitations. In summary, in order to solve a series of problems with existing permeable asphalt, the market urgently needs to find a colored permeable asphalt binder mixed at room temperature with better performance, simpler construction, and lower energy consumption, which cannot meet daily use needs.
