Waterproof roll with electromagnetic shielding function

Abstract

The invention provides a waterproof roll with an electromagnetic shielding function. The waterproof roll comprises a body base layer, a first waterproof layer is arranged on the upper surface of the body base layer, a second waterproof layer is arranged on the lower surface of the body base layer, a first conductive rubber layer is arranged on the upper surface of the first waterproof layer, a second conductive rubber layer is arranged on the lower surface of the second waterproof layer, and surface protection layers are arranged on the other surface of the first conductive rubber layer and the other surface of the second conductive rubber layer. The body base layer is a non-woven fabric layer, the first waterproof layer and the second waterproof layer are SBS modified asphalt layers, the first conductive rubber layer and the second conductive rubber layer are made of a graphene / natural rubber nanocomposite, and the surface protection layers are made of PE films. According to the waterproof roll, the adhesiveness between every two layers is high, the preparing process is simple, the electromagnetic shielding effect of the polymer modified asphalt waterproof roll can be greatly improved, the demands of the current building industry and the market are met, and high application value is achieved.

Description

technical field [0001] The invention relates to a waterproof material for construction engineering, in particular to a waterproof coiled material with electromagnetic shielding effect. Background technique [0002] Waterproof materials are widely used in the engineering waterproofing of roofs and basements of various industrial and civil buildings, as well as engineering waterproofing of municipal and water conservancy facilities such as subways, tunnels, highway bridges, etc. The current waterproof membranes have poor resistance to damage and are prone to puncture Or tear phenomenon, need to spend manpower, material resources to repair, shorten the service life of waterproof material, cause the waste of resources and funds. [0003] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need waterproofing, waterproof membranes need to be laid in advance. At present, the commonl...

AI Technical Summary

Problems solved by technology

At present, the commonly used waterproof membrane is polymer modified asphalt. According to the different places where the waterproof membrane is applied, certain special properties must be given to the waterproof membrane. For example, in areas with serious electromagnetic radiation pollution, waterproof membranes are required. It has a certain electromagnetic shielding effect, but the current waterproof membrane does not have the effect of electromagnetic shielding, and with the rapid development of electromagnetic technology and the application of more and more electronic and electrical devices, various electromagnetic waves of different frequencies with energy It has brought great interference to people's health and living environment, and at the same time constitutes "electromagnetic radiation pollution" in life. Medical equipment and precision instruments are easily interfered by electromagnetic waves, and improper handling in the military and economic fields will cause great harm. damage, so the increasing importance of electromagnetic shielding issues
