Embodiment 1

[0100] Process flow of the present invention, its steps are:

[0101] The first step, at first carry out the preparation of solvent composition 1, solvent composition is made up of solvent by mass ratio by methyl isobutyl ketone: ethylene glycol butyl ether: n-butanol=3.7: 2.3: 0.9;

[0102] The second step, the preparation of resin solution 2:

[0103] Solvent and resin form a resin solution, the mass ratio of which is solvent: resin = 55%: 45%. Add the resin to the solvent at a constant speed and slowly, heat and stir with a strong stirrer, reflux at 60°C for 30 minutes, and the resin dissolves The liquid is uniform and transparent;

[0104] The preparation of the 3rd step, bottom carbon black spray composition 4:

[0105] The bottom carbon black spray coating composition is composed of resin solution and carbon black, and the composition whose mass ratio is 75%:25% is stirred evenly to prepare the bottom carbon black spray coating solution, which is sealed for use;

[01...

Embodiment 2

[0118] The first step, at first carry out the preparation of solvent composition 1:

[0119] The solvent composition is composed of methyl isobutyl ketone by mass ratio: ethylene glycol butyl ether: n-butanol=3.9: 2.1: 1.0 to form a solvent;

[0120] The second step, the preparation of resin solution 2:

[0121] Solvent and resin form the resin solution, and its mass ratio is solvent: resin = 57%: 43%. Add the resin to the solvent at a uniform speed and slowly, heat and stir with a strong stirrer, and condense and reflux for 35 minutes at (65°C). The resin solution should be uniform and transparent;

[0122] The preparation of the 3rd step, bottom carbon black spray composition 4:

[0123] The bottom carbon black spray coating composition is composed of resin solution and carbon black, and its mass ratio is (78%: 22%). The composition is stirred evenly and prepared into the bottom carbon black spray coating solution, which is sealed for use;

[0124] The fourth step, the pr...

Embodiment 3

[0136] ①Solvent preparation:

[0137] Weigh methyl isobutyl ketone according to the following mass ratio: ethylene glycol butyl ether: n-butanol=4.0: 2.2: 1.1 composition and stir evenly to be prepared as solvent;

[0138] ② Preparation of resin solution:

[0139] Solvent and resin form the resin solution, and its mass ratio is solvent: resin = 58%: 42%. Add the resin to the solvent at a uniform speed and slowly, heat and stir with a strong stirrer, and condense and reflux for 45min at (70°C). The resin solution can be uniform and transparent;

[0140] ③. Preparation of bottom carbon black spray composition:

[0141] Take by weighing resin solution by following mass ratio: carbon black=80%: the composition of 20% is stirred evenly and is mixed with bottom carbon black spray coating solution, seals up for use;

[0142] ④. Preparation of surface absorbing composite coating composition:

[0143] Take the resin solution by weighing the following mass ratio: β silicon carbide: ...

Abstract

A wave-absorbing composite nano-paint for military purpose, communication equipment, etc is prepared from methylisobutyl methanone, ethanediol butylether, n-butanol, resin, nano-silicon carbide, Ni nanoparticlels and carbon black through dissolving resin in solvent, preparing the bottom and surface wave-absorbing materials, mixing, stirring, and ball grinding. Its advantages are high absorptivity to electromagnetic waves, with bandwich, and low cost.

Description

technical field [0001] The invention relates to a coating, and is especially suitable for a composite nano wave-absorbing coating composition and a preparation and spraying method thereof. Background technique [0002] my country has invested a lot of manpower and funds in absorbing materials, and achieved certain results, but there is still a big gap between my country and foreign developed countries in the fields of military and aerospace, and there is an urgent need to solve the problem of absorbing materials with excellent performance. [0003] The research on absorbing materials has developed rapidly abroad. From the 1970s to 1980s, the United States, the former Soviet Union and other countries have invested a lot of energy in this research and achieved remarkable results. Since the 1990s, developed countries have also regarded their technology as a new technology with priority in their competitive strategy. [0004] The demand in the field of electromagnetic wave prot...
