Abstract

The invention provides a waterproof roll with the electromagnetic shielding function. The waterproof roll comprises a base layer, a conductive fabric layer, a modified asphalt layer and an isolating layer. The modified asphalt layer is prepared from 40-80 parts of matrix asphalt, 2-25 parts of a softening agent, 5-35 parts of SBS, 5-25 parts of a modifying agent, 1-35 parts of conductive filler, 5-20 parts of filler and 0.2-1 part of an antioxidant. The base layer is made of a long fiber polyester base material, and the thickness ranges from 1 mm to 2 mm. The waterproof roll with the electromagnetic shielding function has excellent waterproofness and electromagnetic shielding performance.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a waterproof coiled material with electromagnetic shielding function and a preparation method thereof, belonging to the field of waterproof materials. Background technique [0002] As we all know, with the rapid development of modern electromagnetic technology and the application of more and more electronic and electrical devices, various electromagnetic waves of different frequencies with energy have brought great interference to people's health and living environment. It constitutes "electromagnetic radiation pollution". Medical equipment and precision instruments are easily interfered by electromagnetic waves, and improper handling in the military and economic fields will cause great damage. Therefore, the problem of electromagnetic shielding has become increasingly important. [0003] Shielding electromagnetic radiation pollution to limit it to a certain area has become one of ...
