Embodiment 1

[0021] Embodiment 1: A kind of flexible patch of absorbing material, such as figure 1 As shown, it includes a protective layer 1, a conductive substrate layer 2, an adhesive layer 3 and a release paper layer 4 from top to bottom. The protective layer 1 is polyurethane resin 101, and the thickness of the protective layer 1 is 0.02mm. The conductive substrate layer is nickel-plated conductive nylon fiber, the thickness of the conductive substrate layer 2 is 0.05 mm, and the adhesive layer 3 is an acrylic pressure-sensitive adhesive, and the thickness of the adhesive layer 3 is 0.03 mm.

[0022] The preparation method of the flexible patch of the above-mentioned wave-absorbing material is to select nickel-plated conductive nylon fibers, apply acrylic pressure-sensitive adhesive to one side, then attach cellophane to the pressure-sensitive adhesive, and coat the other side of the nylon fiber with polyurethane resin.

Embodiment 2

[0023] Embodiment 2: A kind of flexible patch of absorbing material, such as figure 1 As shown, it includes a protective layer 1, a conductive substrate layer 2, an adhesive layer 3 and a release paper layer 4 from top to bottom. The protective layer 1 is a water-based resin 90, and the thickness of the protective layer 1 is 0.05mm. The conductive substrate layer is silver-plated conductive nylon fiber, the thickness of the conductive substrate layer 2 is 0.15 mm, and the adhesive layer 3 is a silicone pressure-sensitive adhesive, and the thickness of the adhesive layer 3 is 0.08 mm.

[0024] The preparation method of the flexible patch of the above-mentioned wave-absorbing material is to select silver-plated conductive nylon fibers, apply silicone pressure-sensitive adhesive to one side, then attach cellophane to the pressure-sensitive adhesive, and coat the other side of the nylon fibers with water-based resin.

Embodiment 3

[0025] Embodiment 3: a kind of flexible patch of absorbing material, such as figure 1 As shown, it includes a protective layer 1, a conductive substrate layer 2, an adhesive layer 3 and a release paper layer 4 from top to bottom. The protective layer 1 is epoxy resin, and the thickness of the protective layer 1 is 0.04mm. The conductive substrate layer is nickel-plated conductive nylon fiber, the thickness of the conductive substrate layer 2 is 0.10 mm, and the adhesive layer 3 is an acrylic pressure-sensitive adhesive, and the thickness of the adhesive layer 3 is 0.05 mm.

[0026] The preparation method of the flexible patch of the above-mentioned wave-absorbing material is to select nickel-plated conductive nylon fibers, apply acrylic pressure-sensitive adhesive to one side, then attach cellophane to the pressure-sensitive adhesive, and coat the other side of the nylon fiber with epoxy resin.

Abstract

The invention discloses a flexible paster of a wave absorption material and a preparation method and a use method of the flexible paster. The flexible paster comprises a protection layer, a conductivebase material layer, an adhesive layer and a peel paper layer from top to bottom in sequence. The preparation method comprises the following steps: coating a single side of a nickel / silver plated conductive nylon fiber with an acrylic acid pressure sensitive adhesive or an organic silicon pressure sensitive adhesive, further pasting glass paper to the pressure sensitive adhesive, and coating theother side of the nylon fiber with any one of a polyurethane resin, an aqueous resin and an epoxy resin. By adopting the flexible paster, the defects of on-site cutting, tedious splicing, tedious construction, long production cycles and poor pasting appearance quality in the prior art can be overcome, rapid pasting can be carried out according to unknown shapes on a construction site, on-site cutting and splicing are reduced, the labor, materials and financial resources can be saved, and high pasting quality can be achieved; the preparation method is simple to operate, convenient in preparation, short in procedure and applicable to large-scale industrial production; and in addition, by adopting the use method, an optimal pasting quality state can be achieved for the flexible paster.

Description

technical field [0001] The invention relates to a flexible patch, in particular to a flexible patch of a wave-absorbing material and a preparation and use method thereof. Background technique [0002] Coating absorbing materials on aircraft, missiles, tanks, ships, warehouses and other weapons and equipment and military facilities can absorb reconnaissance waves and attenuate reflected signals, thereby breaking through the enemy's radar defense zone. This is a powerful anti-radar reconnaissance method. It is a method to reduce the attack of infrared guided missiles and laser weapons on weapon systems. For example, because the US B-1 strategic bomber is coated with absorbing material, its effective reflection section is only 1 / 50 of that of the B-52 bomber; after coating the absorbing material on the fairing of the 0H-6 and AH-1G Cobra helicopter engines It can reduce the infrared radiation of the engine by about 90%. During the Gulf War in 1990, the first F-117A aircraft t...
