AI Technical Summary
In the existing technology, asphalt peeling phenomenon leads to reduced bonding strength, insufficient water resistance, easy deformation of hot melt adhesives at high temperatures, serious odor and coloring problems, and existing modified petroleum resins fail to meet the requirements of heat resistance, low odor and high bonding strength.
By preparing modified hydrogenated petroleum resin within a specific bromine value, silane modification amount and molecular weight range, and combining a silane-containing compound with a specific structure with an asphalt composition, the water resistance and bonding strength of the asphalt are improved, the odor is reduced and the appearance is improved.
The water resistance of asphalt is improved, and the heat resistance and low odor properties are improved. It also has good coating properties and high bonding strength, solving the problems of asphalt peeling and deformation and odor of hot melt adhesives.
