Abstract

The present invention provides a material with characteristics of fire retardation, thermal insulation and wave absorption. The material comprises a base layer, wherein the base layer is mesh fabric, both sides of the mesh fabric are coated with an adhesive coating layer, and the adhesive coating layer is a polyvinylchloride adhesive coating layer. The adhesive coating layer comprises a wave absorption agent, wherein the wave absorption agent comprises nickel-plated glass beads, and a mass ratio of the wave absorption agent powder to the adhesive is 0.17-1.85:1. The present invention further provides a preparation method for the material. According to the material with characteristics of fire retardation, thermal insulation and wave absorption in the present invention, the polyvinylchloride adhesive is added with the wave absorption agent, such that functions of fire retardation, thermal insulation and wave absorption can be concurrently provided; the material of the present invention can concurrently has functions of fire retardation and thermal insulation, and characteristics of high wave absorption strength, wide wave absorption frequency band, and small surface density; and the material of the present invention can be used for wave absorption defilading, electromagnetic shielding, and the like.

Description

technical field [0001] The invention belongs to the application field of flame-retardant, heat-insulating and wave-absorbing materials, and relates to a flame-retardant heat-insulating, wave-absorbing material and a preparation method thereof, in particular to a light-weight, broadband flame-retardant heat-insulating, wave-absorbing material and its Preparation. Background technique [0002] With the continuous improvement of reconnaissance and detection methods and people's attention to the hazards of electromagnetic radiation, the research of new wave-absorbing materials has become a hot spot of attention. Commonly used wave-absorbing materials are difficult to integrate flame retardancy, heat insulation and wave-absorbing stealth. [0003] Chinese patent 1651524A (publication number) discloses a composite coating type absorbing material containing carbon nanotubes and its preparation method. The material is composed of polymers and carbon nanotubes. The dielectric loss of...
