preparation example Construction

[0029] The method for preparing a marine environment-resistant metamaterial base material provided by the present invention is to prepare a metamaterial base material by mixing ceramic powder and additives in a raw rubber matrix, specifically comprising the following steps: mixing raw rubber, ceramic powder, and vulcanizing agent Blending with additives in proportion; followed by banbury blending and thermocompression molding to prepare the marine environment-resistant metamaterial base material.

[0030] figure 1 It is a process flow diagram of a method for preparing a metamaterial base material resistant to a marine environment according to a preferred embodiment of the present invention. Such as figure 1 As shown, the elastomer powder, ceramic powder, and silane coupling agent are first blended in proportion, and the contents of each component are: 100 parts of raw rubber, 40-330 parts of ceramic powder, 0.7-6 parts of vulcanizing agent and 0.4-15 parts of additives, opti...

Embodiment 1

[0033] After blending 100 parts of EPDM rubber, 40 parts of SiC ceramic powder, 1 part of dicumyl peroxide, 0.5 part of stearic acid, 0.5 part of anti-aging agent and 0.5 part of silane coupling agent, put it into the mixer In the machine, banbury blending is carried out at a temperature of 70°C to make the components evenly mixed; the mixture obtained after banbury mixing and blending is put into a flat-plate hot press machine for hot press molding, wherein the pressure of hot press molding 25MPa, hot-pressed at 170°C for 10 minutes, and dried to obtain a marine environment-resistant metamaterial substrate. The prepared marine environment-resistant metamaterial substrate can have different thicknesses and can be attached.

Embodiment 2

[0035] 100 parts of nitrile rubber, 150 parts of BaTiO 3Ceramic powder and 2 parts of dicumyl peroxide, 1 part of stearic acid, 1 part of anti-aging agent, and 1 part of silane coupling agent are ball-milled and blended in a full-range planetary ball mill. After blending, the mixture is put into a compact In the mixer, banbury blending is carried out at a temperature of 60°C, so that the components are mixed uniformly; the mixture obtained after banbury blending is put into a hot press machine, and hot press molding, wherein, the pressure of hot press molding 20MPa, hot-pressed at 150°C for 30 minutes, and dried to obtain a marine environment-resistant metamaterial substrate. The prepared marine environment-resistant metamaterial substrate can have different thicknesses and can be attached.

Abstract

The invention discloses a marine environment resistant metamaterial substrate, which is prepared from the following components by mass: 100 parts of raw rubber, 40-330 parts of ceramic powder, 0.7-6 parts of a vulcanizing agent and 0.4-15 parts of an assistant. The preparation method includes: blending the raw rubber, ceramic powder, the vulcanizing agent and the assistant in proportion; and thenconducting banburying mixing and hot press molding in order to obtain the marine environment resistant metamaterial substrate. The marine environment resistant metamaterial substrate provided by the invention is realized by mixing ceramic powder ceramic powder and the assistant into the raw rubber matrix, can be prepared into different thicknesses according to needs and has good attaching performance, and can be used for preparation of marine environment resistant wave-absorbing metamaterials.

Description

technical field [0001] The invention relates to the field of materials, and more specifically, to a marine environment-resistant metamaterial substrate and a preparation method thereof. Background technique [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature. [0003] In the prior art, metamaterial substrates used to prepare metamaterials are usually prepared using ceramics, polymer materials, ferroelectric materials, ferrite materials or ferromagnetic materials. However, the performance of existing metamaterial substrates is poor, for example, high cost (including design cost, raw material cost, processing cost, t...
