Abstract

The invention relates to the technical field of porous wave-absorbing materials, in particular to a preparation method of a rapid curing type porous wave-absorbing coating material. The preparation method of the rapid curing type porous wave-absorbing coating material comprises the following steps: preparing a spraying agent; carrying out spraying treatment; and curing and molding the coating. According to the method, rapid curing of the porous wave-absorbing coating material is achieved through a three-step method including spraying agent preparation, spraying treatment and coating curing forming, the maintenance time of the wave-absorbing coating is greatly shortened, manpower and material resources are reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of porous wave absorbing materials, in particular to a preparation method of a fast-curing porous wave absorbing coating material. Background technique [0002] The absorbing coating is mainly used to coat the outer surface of the object to achieve the purpose of absorbing electromagnetic waves, and its composition mainly includes absorbing agent, adhesive and auxiliary agent. Absorber is the key component that determines the wave-absorbing performance of wave-absorbing coating. At present, the absorbers with relatively mature technology and wide application range mainly include ferrite, carbonyl iron, conductive polymer, etc.; the binder mainly acts as adhesion And wave transmission, the most widely used organic resin systems such as epoxy resin and polyurethane. [0003] Due to the large coating area of ​​the wave absorbing coating, its coating uniformity and the structure and shape of the coating substra...
