AI Technical Summary

Technical Problem

The existing waterproof coils have defects in weather resistance, flame retardant properties and UV resistance during long-term exposure, resulting in a shortened service life and a reduced waterproof effect.

Method used

An exposed coating composite layer formed by a modified asphalt layer and a glass fiber cloth with specific performance parameters is combined with a reinforcement layer and an optional isolation layer to form a weather-resistant exposed coating composite waterproof coil. The modified materials contain bitumen, polyaluminum chloride, cycloane oil, SBS, SBR, tris(2,3-dichloropropyl) phosphate, SIS, 3-methyltetrahydrothiazole-2-thioone, gumalon resin and aluminum hydroxide.

Benefits of technology

It realizes the waterproof coil resistance to ultraviolet aging, excellent weather resistance, good viscosity, strong flame retardant and tensile performance of the waterproof coil, and is easy to construct and firmly bonded to the base surface.
