Description

Technical Field

[0001] The present invention relates to the technical field of pavement materials, and in particular to an all-solid waste imitation asphalt material and a preparation method and application thereof. Background Art

[0002] Asphalt, with its excellent adhesion and waterproof properties, is widely used in road construction and construction. In road construction, asphalt is one of the primary materials for paving roads, providing a smooth and comfortable driving surface for vehicles. In construction, it is primarily used to manufacture oil paper, felt, waterproof coatings, and asphalt caulking pastes for roofing and underground waterproofing. However, asphalt is highly thermally sensitive. While solid or semisolid at room temperature, it readily melts with increasing temperatures, rendering it less effective at high and low temperatures. Furthermore, asphalt is susceptible to environmental influences and aging. Under the long-term effects of heat, sunlight, oxygen, and moisture, low-molecular-weight components in petroleum asphalt transform into high-molecular-weight components, reducing its plasticity and increasing its viscosity. Asphalt gradually becomes brittle and hard, eventually cracking and losing its usability. Furthermore, during production and use, asphalt can release hazardous substances, posing a threat to the environment and human health. Therefore, the development of alternative materials with similar or superior properties has become a hot research topic.

[0003] In the prior art, the use of polymers to prepare asphalt-like materials is a common method. These materials, using synthetic rubber, synthetic resin, or a blend of both as a base material, are then added with appropriate chemical additives and fillers, and processed through a series of steps to create a rollable sheet-like material with asphalt-like properties. Other methods combine inorganic and polymer materials, leveraging the rigidity of the inorganic material and the flexibility of the polymer to produce high-performance asphalt-like materials. However, the high production costs of existing asphalt-like materials make them difficult to replace asphalt in large-scale road construction applications. Furthermore, the properties of existing asphalt-like materials, such as penetration, softening point, and ductility, do not yet match those of conventional asphalt, resulting in inferior mechanical properties of asphalt-like mixtures prepared using these materials.

[0004] Based on this, developing an asphalt-like material with good adhesion and low cost has important practical significance for road construction. Summary of the Invention

[0005] To address the high production costs of existing asphalt-like materials and the fact that their performance cannot reach the level of traditional asphalt, resulting in poor mechanical properties of asphalt-like mixtures prepared using these materials, the present invention provides an all-solid waste asphalt-like material, its preparation method, and its application. The raw materials for this all-solid waste asphalt-like material include waste rubber powder, waste plastics, waste cooking oil, waste petroleum resin, and waste fillers. By utilizing the interactions of these raw material components and combining them with a specific preparation method, the all-solid waste asphalt-like material exhibits excellent road performance. Furthermore, since all the raw material components are waste, the preparation cost is low and readily available, effectively alleviating the burden of solid waste disposal.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0007] The first aspect of the present invention provides an all-solid waste asphalt-imitation material, comprising the following raw material components in parts by weight: 60-80 parts of waste rubber powder, 20-50 parts of waste plastics, 5-15 parts of waste kitchen grease, 5-15 parts of waste petroleum resin, and 20-30 parts of waste fillers;

[0008] The waste filler includes the following raw material components in percentage by mass: 20%-30% of waste glass fiber, 15%-20% of straw residue, 15%-20% of waste clay and the remainder of coal gangue powder.

[0009] Compared to the existing technology, the present invention utilizes waste rubber powder, waste plastic, waste cooking oil, waste petroleum resin, and waste fillers as the main raw materials to prepare an all-solid waste asphalt-like material. The waste rubber powder and waste plastic possess a certain degree of elasticity and toughness, which can impart the asphalt-like material with excellent high-temperature deformation resistance and low-temperature flexibility, thereby helping to improve the durability of the asphalt-like material. Furthermore, some components in the waste rubber powder and waste plastic can resist the aging effects of ultraviolet rays, slowing the aging rate of the asphalt-like material. The fatty acids contained in the waste cooking oil can, to a certain extent, increase the fluidity and needle penetration of the asphalt-like material, enabling it to better adapt to road deformation under different temperature environments. Furthermore, the waste cooking oil can enhance the adhesion between the asphalt-like material and aggregate, thereby improving the mechanical strength and stability of the road surface, helping to resist the effects of vehicle loads, improving the quality and durability of the road surface, and reducing the occurrence of road surface diseases.

[0010] The addition of waste petroleum resin forms strong intermolecular forces with other components of the asphalt-like material, effectively enhancing its internal cohesion and increasing its overall bond strength and softening point. Furthermore, waste petroleum resin improves the bond between the asphalt-like material and the base layer, increasing adhesion and friction between the two, making it less likely to separate from the base layer and improving the overall stability of the pavement. More importantly, waste petroleum resin exhibits both heat and cold resistance, reducing the temperature sensitivity of the asphalt-like material. In high-temperature environments, it reduces its fluidity, maintaining good pavement smoothness and rutting resistance. In low-temperature environments, it increases the material's flexibility, preventing cracks caused by thermal contraction.

[0011] The waste filler materials used in the present invention include waste glass fiber, straw residue, waste clay, and coal gangue powder. Waste glass fiber has high strength and modulus, effectively bearing and transmitting stress, reducing stress concentration. Furthermore, waste glass fiber acts as a skeletal support, limiting deformation of the asphalt-like material and preventing the expansion of microcracks, thereby enhancing the asphalt-like material's compressive strength and improving its road performance. Straw residue has a certain fiber structure and strength, which can share some of the stress under vehicle loads, reducing deformation and damage to the asphalt-like material and extending the service life of the pavement material. Furthermore, the unique fiber structure of straw residue has a certain degree of flexibility and elasticity, which can absorb and buffer stress caused by low-temperature shrinkage, reducing the probability of cracks in the pavement material under low-temperature conditions. Waste clay has certain high-temperature resistance properties, which can improve the thermal stability of the asphalt-like material and reduce its thermal expansion coefficient. The waste clay particles also act as a dispersion medium, ensuring a more uniform distribution of the various components in the asphalt-like material, helping to improve the overall stability of the material. The addition of coal gangue powder can give the imitation asphalt material higher hardness and rigidity, improve the compressive strength and fatigue resistance of the pavement material, and extend the service life of the pavement material under alternating loads.
