Abstract

The present invention relates to an anticorrosive foam plastic composite material, which is formed by compounding a plurality of core-like structures, wherein the core part of the core-like structure is a nanometer metal, the middle part wrapping the core part is a foam plastic composite material, and the shell part wrapping the middle part is poly o-phenylenediamine. The invention further relates to a preparation method of the anticorrosive foam plastic composite material. According to the present invention, the nanometer metal is protected by the poly o-phenylenediamine, and the foam plastic composite material is used as the middle layer, such that the formed structure has advantages of compactness, firmness and light weight, the nanometer metal is effectively subjected to double protection with the poly o-phenylenediamine and the foam plastic composite material, and advantages of no pollution, strong firmness and corrosion resistance are provided.

Description

technical field [0001] The invention belongs to the technical field of composite plastics, and relates to an anti-corrosion foamed plastic composite material and a manufacturing method thereof. Background technique [0002] In recent years, with the development of navigation and river transportation, the requirements for the use of ships are higher. It is necessary to prevent the hull from being corroded by chemical substances in the water, such as salts, and to prevent the materials used from polluting the water. It is also necessary to consider whether the outer body of the hull is easy to age and damage, and the existing hull is generally easy to corrode. After one or two years of use, some rust spots will appear, and the hull is heavy and consumes a lot of energy. question. Not only that, due to the deteriorating electromagnetic wave environment in the ocean, in order to conduct electronic simulation and other tests, it is urgent to build a non-echo anechoic chamber tha...
