Description

Technical Field

[0001] The present invention belongs to the technical field of road engineering materials, and particularly relates to a resin-based bio-based high-viscosity adhesive material for a skid-resistant wearing course pavement and a preparation method thereof. Background Art

[0002] With the continuous increase in traffic volume and the deterioration of road use environment, the skid resistance and wear resistance of roads are facing severe tests. The slip phenomenon on the road surface not only reduces the driving safety but also increases the frequency and cost of road maintenance. Therefore, improving the skid resistance and wear resistance of the road surface has become an urgent problem to be solved in the field of road engineering.

[0003] Traditional road surface treatment methods such as asphalt pavements and cement concrete pavements often have certain limitations in terms of wear resistance and skid resistance. Especially under high-temperature, high-humidity, and high-load conditions of frequent traffic, conventional pavement materials are prone to surface aging, wear, and slip, resulting in a decline in pavement performance and seriously affecting driving safety and road service life.

[0004] At present, although some skid-resistant and wear-resistant materials have been widely used in road construction, such as modified asphalt, rubber asphalt, etc., these materials still have some deficiencies. On the one hand, the persistence of skid resistance and wear resistance is poor, and it is easy to lose its effect during long-term use; on the other hand, the existing pavement repair materials usually have a weak adhesion to the substrate and are difficult to effectively form a long-term stable bond with different types of pavements (such as cement pavements, asphalt pavements, etc.).

[0005] In order to improve the skid-resistant wear performance of roads and extend the service life of pavements, researchers have continuously innovated in the development of road engineering materials, especially in terms of high bond strength and wear resistance. The resin-based bio-based high-viscosity adhesive material for precast pavements based on high-performance binders has become an ideal solution. Such materials can not only enhance the skid resistance and wear resistance of the road surface but also effectively solve the problem of insufficient adhesion, ensuring that the pavement maintains excellent performance for a long time under high-intensity traffic loads and harsh environmental conditions.

[0006] CN116694094A discloses an environmentally friendly slow-adhesion and odorless high-viscosity adhesive powder modified asphalt, which is composed of the following raw materials in parts by weight: 70 - 83 parts of matrix asphalt, 8 - 18 parts of desulfurized rubber powder, 2 - 4 parts of thermoplastic styrene-butadiene rubber, 0.02 - 0.2 part of a synergistic reaction type odorless agent, 0.5 - 2 parts of a physical odorless agent, 0.5 - 1.5 parts of a slow-adhesion agent, 0.5 - 1 part of an antioxidant, 0.01 - 0.02 part of a silane coupling agent, and 3 - 5 parts of a stabilizer, but its low-temperature resistance and anti-fatigue life are relatively low.

[0007] CN112694296A discloses a cold recycling joint binder for asphalt pavement in road surface reconstruction and expansion, and the binder consists of a powder component and a liquid component. The powder component is prepared by mixing cement, fine sand, red mud, fly ash, water reducer, expansive agent, thickening agent, defoamer I, thixotropic agent, polymer rubber powder and dispersant in specific weight ratios. The liquid component is prepared by mixing chlorinated ether resin emulsion, water, defoamer II, stabilizer and wetting agent. However, its bonding performance needs to be improved and its storage performance is not high.

[0020] The present invention also discloses a preparation method of the resin - type bio - based high - viscosity adhesive material for the anti - skid wear - resistant layer pavement, comprising the following steps: S1: Heat the asphalt to 150 - 180 °C and stir for 20 min to obtain molten asphalt; S2: Mix the vulcanized rubber powder with petroleum resin until the surface of the vulcanized rubber powder is uniformly wetted to obtain pretreated vulcanized rubber powder; S3: Heat the resin matrix to 70 °C, and then stir at a rotation speed of 4000 - 6000 r / min for 20 - 30 min to obtain molten resin matrix; S4: Mix the pretreated vulcanized rubber powder with the molten resin matrix, then add the molten asphalt, and then raise the temperature of the system to 120 - 140 °C, and stir at a rotation speed of 1000 - 3000 r / min for 15 - 30 min to ensure uniform mixing to obtain the base material; S5: Add tackifier, plasticizer and curing agent into the base material, stir at a speed of 1000 - 3000 r / min for 10 min; then add antioxidant, heat stabilizer and additives, raise the system temperature to 120 - 140 °C, and shear at a speed of 3000 r / min for 20 min to obtain the primary material. S6: Hot press and cure the primary material at 130 - 140 °C for 2 - 4 h to obtain the product.

[0021] The beneficial effects of the present invention are as follows: 1. In the present invention, the plant asphalt provides the adhesion and flexibility at high temperatures. The plant asphalt has a high softening point, which can prevent the adhesion failure under high-temperature environments. Through the compounding of various asphalts such as plant asphalt, coal tar pitch and petroleum asphalt, the material can firmly adhere to the road surface under high-temperature, high-humidity and low-temperature conditions, effectively avoiding the peeling problem during use, and improving the durability of the overall road surface repair.

[0022] 2.

[0023] 3. In the present invention, the interaction between polyurethane and styrene-butadiene copolymer significantly improves the flexibility of the material, enabling the obtained material to effectively adapt to the micro-deformation of the road surface; the use of plasticizer and curing agent ensures that the material still has excellent fatigue resistance in harsh environments.

[0024] 4. In the present invention, through the wetting effect between the surface of the rubber powder and the petroleum resin, the vulcanized rubber powder can be tightly combined with the resin matrix, optimizing the overall toughness and durability of the material.

[0025] 5. In the present invention, the organosilicon-modified cross-linking agent undergoes a condensation reaction to form a silicone network structure, which is combined with the epoxy resin or polyurethane resin matrix at the same time, significantly improving the heat resistance and weather resistance of the material, and enabling it to remain stable under high-temperature, low-temperature and humidity changes.

[0026] 6. In the present invention, by adding bio-based materials such as epoxidized soybean oil and citrus flavonoids, it is not only environmentally friendly, but also increases the plasticity and antioxidant properties of the product, while significantly reducing the road maintenance frequency and cost.
