AI Technical Summary
Existing self-adhesive SBS bitumen waterproof membranes have poor high-temperature resistance and insufficient aging resistance, making them prone to problems such as blistering, cracking, and leakage. After the self-adhesive layer ages, it is prone to hollowing and leakage.
The modified asphalt is prepared by combining an SBS asphalt waterproof layer and a concrete adhesive layer, adding nano-titanium dioxide, antioxidants and microcapsule repair agents in a specific ratio, and using a low-temperature mixing process. Water-soluble wall materials are used to coat the microcapsule repair agents to improve their high-temperature resistance and aging resistance.
It significantly improves the high temperature resistance and aging resistance of waterproof membranes. The microcapsule repair agent can effectively repair damage and restore function after aging, ensuring that the membrane maintains excellent performance in high temperature and humid environments.
