According to the coating material disclosed by the embodiment of the application, the components play a synergistic effect by controlling the types and the contents of the components, so that the coiled material formed by the coating material is endowed with good stability, adhesiveness and durability, and the service life of the coiled material is prolonged.
According to embodiments of the present application, the base asphalt acts as a base material for the capstock, may act as a binder for the remaining components of the capstock, and provides waterproofing and bonding properties to the capstock. The base asphalt mainly comprises asphaltene, saturates, aromatics and colloids, which interact with each other to form solution-gel type asphalt micelles, which have attraction, and the base asphalt has an elastic effect, so that the coiled material formed by the coating material has certain elasticity.
In some embodiments, the penetration of the matrix pitch is 60 (1/10 mm) to 300 (1/10 mm). Matrix asphalts in this penetration range have moderate levels of softness and resistance to shear failure and are more compatible with the remaining components of the capstock.

Moreover, the saturated component in the base oil can fully swell the thermoplastic elastomer, the compatibility of the matrix asphalt and the thermoplastic elastomer can be improved, and the matrix asphalt and the thermoplastic elastomer are mixed more uniformly. The base oil can also be used as a diluent compatible with the thermoplastic elastomer, so that the interaction between high molecular chains is reduced, the mobility of the molecular chains is enhanced, the tensile strength of the material is reduced, and the impact strength is improved. Illustratively, the base oil is # 61 base oil.
In some embodiments, the oil is 1 to 10 parts by weight. The oil component with the content is added into the base asphalt to form a mixture, so that the penetration degree of the mixture is properly improved, and the bonding and low-temperature performance of the aged base asphalt can be improved.

By adjusting the mass ratio of the aromatic oil to the base oil, the bonding and low-temperature performance of the aged matrix asphalt can be further improved.
According to the embodiment of the application, the thermoplastic elastomer as one of the modifiers for modifying the matrix asphalt can be aggregated by different or same high molecular polymers to form a network structure, and after the thermoplastic elastomer is added into the matrix asphalt, the thermoplastic elastomer is distributed in the matrix asphalt in a continuous phase in a discrete phase state, and undergoes swelling action with saturated components and aromatic components in the matrix asphalt, and the swelling action can further improve the dispersion uniformity of the thermoplastic elastomer. In addition, the thermoplastic elastomer can absorb small molecules such as saturated components and aromatic components in the matrix asphalt, so that the large molecules and polar substances in the whole system are increased, and the strength, the adhesion, the high-temperature performance and the crack resistance of the coating material are improved.
