Description

technical field [0001] The invention relates to the field of waterproof materials for buildings, in particular to a novel nano-alloy root-resistant composite coil and a preparation method thereof. Background technique [0002] The number of newly built buildings in the country is huge every year. In addition to the renovation of dilapidated houses, old houses and energy-saving renovation of existing buildings, the total construction area reaches billions of square meters, and the demand for waterproof materials is huge. At the same time, new and higher requirements are put forward for waterproof materials, such as improving the flame retardancy of materials, reducing material costs, and expanding material functions. The existing waterproof membranes are prone to deformation of the base layer during use, and the withstand strength is small, and the tensile and tear resistance properties are poor. Due to the need to spread during use, the waterproof membrane needs to be stretc...

AI Technical Summary

Problems solved by technology

The existing waterproof membranes are prone to deformation of the base layer during use, and the withstand strength is small, and the tensile and tear resistance properties are poor. Due to the need to spread during use, the waterproof membrane needs to be stretched, and it is easy to stretch during the stretching process. Deformation and tearing of the waterproof membrane will affect the normal use of the waterproof membrane

[0003] Since the waterproof membrane can be used as an exposed waterproof membrane, after a long period of solar radiation and rainwater erosion, the waterproof membrane is easily corroded, especially in recent years, the air pollution has been serious, and the corrosive substances contained in the rainwater are more More, the corrosion performance of the waterproof membrane is enhanced. Once the waterproof membrane is corroded, the service life of the waterproof membrane is greatly reduced. The existing exposed waterproof membrane has poor heat insulation performance, and the non-exposed waterproof membrane It cannot effectively dredge the plant root system, which is not conducive to the growth of plants

In addition, the existing method of membrane bonding performance is poor, so that the bonding between the waterproof membrane and the substrate is not strong enough, so that the waterproof effect is relatively weak, affecting the overall performance of the waterproof layer, the construction environment is limited, and it cannot be used in a rainwater environment. Construction under certain conditions will increase the construction period and increase the cost
