Ultra-low-temperature SBS modified bitumen waterproof membrane

Abstract

The invention relates to an ultra-low-temperature SBS modified bitumen waterproof membrane. The ultra-low-temperature SBS modified bitumen waterproof membrane comprises a base layer. The upper and the lower surfaces of the base layer are provided with a hot melt or self-adhesive layer. The outer surface of the hot melt or self-adhesive layer is provided with an isolation layer. The ultra-low-temperature SBS modified bitumen waterproof membrane is reasonable in structure, good in adhesion and resistant to low temperature, can still maintain waterproof performance at the temperature of -50 DEG C, has good adhesion at low temperature and is especially suitable for cold areas and winter waterproof construction.

Description

【Technical field】 [0001] The invention relates to a waterproof coiled material, in particular to an ultra-low temperature SBS modified asphalt waterproof coiled material with strong adhesion in an ultra-low temperature environment, and belongs to the technical field of waterproof materials. 【Background technique】 [0002] SBS modified waterproof membrane is a commonly used waterproof material in waterproofing projects. It is mainly used in building roofs, underground, subways, tunnels, bridges and other projects to resist rainwater, surface water, groundwater and other forms of water on buildings. The erosion of objects or structures plays a vital role in the durability of building structures. [0003] At present, the commonly used SBS modified asphalt waterproofing membranes in the market are divided into two types: hot-melt type and self-adhesive type. When the ambient temperature of the hot-melt waterproof membrane is lower than -10°C, it is not easy to construct, and th...

Problems solved by technology

[0003] At present, the commonly used SBS modified bitumen waterproofing membranes in the market are divided into two types: hot-melt type and self-adhesive type. When the ambient temperature is lower than -10℃, the hot-melt waterproof membrane is not easy to construct, and the membrane is prone to cracking and other phenomena; when the ambient temperature is lower than 5℃, the adhesive force of the self-adhesive waterproof membrane is obviously reduced, and construction cannot be done.

This situation is especially obvious in cold regions such as the north. In winter, almost all waterproof materials cannot be constructed. Even if it is barely constructed, it will bring great leakage hidden dangers to building safety.
