Problems solved by technology

[0003] At present, penetration and opening seriously affect the effectiveness of electromagnetic shielding, resulting in a significant reduction in shielding effectiveness. The waterproof membrane is required to be dense and seamless in engineering construction. If the waterproof membrane has the function of electromagnetic shielding, it is used in buildings to shield the outside world. Electromagnetic radiation pollution while preventing military and economic information from being stolen through wireless signals to ensure national and economic security
[0004] Although existing patents have disclosed waterproof membranes with electromagnetic shielding functions, it is still difficult to meet the high demand for environmental performance in the current waterproof market

Abstract

The invention discloses a self-adhesive waterproof roll with an electromagnetic shielding function. The self-adhesive waterproof roll comprises an isolation layer, a butyl pressure-sensitive self-adhesive layer, a matrix layer, a butyl pressure-sensitive self-adhesive layer and an isolation layer in sequential lamination. Each butyl pressure-sensitive self-adhesive layer is prepared from, by weight, 5-30 parts of butyl rubber, 5-40 parts of a tackifier, 10-60 parts of a plasticizer, 10-40 parts of nano conductive filler, 10-50 parts of a reinforcing agent, 1-10 parts of a nano activating agent, 0.5-5 parts of a chemical coupling agent, 1-5 parts of an antioxidant and 1-5 parts of a light stabilizer. The self-adhesive waterproof roll with the electromagnetic shielding function is excellentin water resistance, aging resistance and shielding effectiveness, hot melting construction and asphalt smoke are avoided, and harms to human bodies and environments are avoided.

Description

technical field [0001] The invention relates to the field of waterproof coiled material, in particular, the invention relates to a self-adhesive waterproof coiled material with electromagnetic shielding function and a preparation method thereof. Background technique [0002] As we all know, with the rapid development of modern electromagnetic technology and the application of more and more electronic components, various electromagnetic waves with energy and different frequencies constitute "electromagnetic radiation pollution", which has brought great harm to people's health and living environment. At the same time, medical equipment and precision instruments are easily interfered by electromagnetic waves; improper handling of buildings in the military and economic fields will cause irreparable damage, so the problem of electromagnetic shielding has become increasingly important. [0003] At present, penetration and opening seriously affect the effectiveness of electromagnet...
