Abstract

The invention discloses a maintenance-free square cabin capable of absorbing radar waves and provided with an electromagnetic shielding function and belongs to the technical field of square cabins. The maintenance-free square cabin capable of absorbing the radar waves and provided with the electromagnetic shielding function sequentially comprises an outer cover plate, a thermal insulation material layer and an inner cover plate from outside to inside, the outer cover plate is a composite material laminate which comprises an outer layer and an inner layer, the outer layer is wave-transparent materials, and the inner layer is wave-absorbing foam; the thermal insulation material layer is a low-intensity polyurethane rigid foam layer; the inner cover plate is an alloy aluminum plate with continuous electrical conductivity.

Description

technical field [0001] The invention relates to the technical field of shelters, in particular to a shelter wall plate that does not require maintenance and absorbs radar waves and has electromagnetic shielding. Background technique [0002] Traditional shelter panels are generally composed of inner panels, outer panels and polyurethane foam sandwiches, both of which are alloy aluminum panels. The aluminum alloy outer cover board can not absorb radar waves, but also strongly reflects radar waves; the use of stealth coatings or protective nets is easy to damage and difficult to maintain. So far, there is no maintenance-free shelter that absorbs radar waves and has electromagnetic shielding for use by troops. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a shelter wall plate that absorbs radar waves and has electromagnetic shielding without maintenance. The shelter made of...
