preparation example Construction

[0037] The preparation method of the OAPPOSS refers to the literature M.Laine, etal.Octa(aminophenyl)silsesquioxaneasaNanoconstructionSite.J.Am.Chem.Soc.2001,123,12416-12417. The steps are as follows:

[0038] (1) Disperse 8 g of octaphenylpolysilsesquioxane (OPS) in 30-60 mL of nitric acid solution in an ice-water bath, and stir evenly for 30 min.

[0039] (2) Continue to react the OPS nitric acid solution at room temperature for 20 h, filter with suction and wash with water for 5 times to obtain a yellow precipitate.

[0040] (3) Place 8 g of the yellow precipitate obtained in (2) and 1 g of palladium-carbon catalyst in a round-bottomed flask, add 15 mL of tetrahydrofuran (THF) and 15 mL of triethylamine (TEA) under the protection of argon, and heat the reaction solution to 60 ° C. Add 8mL of formic acid and continue the reaction for 10h.

[0041] (4) After the reaction, the mixture was filtered with suction and washed five times with ethyl acetate and water respectively to...

Abstract

The invention provides a graphene-doped anti-radiation coating and a preparation method thereof, and relates to a functional coating. The anti-radiation coating comprises the following components in parts by weight: 40-70 parts of matrix resin, 0.1-0.5 part of graphene, 0.1-0.5 part of octaphenyl amido polysilsesquioxane, 1-5 parts of Fe3O4 nano particles, 1-5 parts of Al2O3 nano powder, 5.0-10 parts of CaCO3, 0.5-1 part of a defoaming agent, 0.5-1 part of a dispersing agent, 0.5-3.0 parts of a film-forming auxiliary and 10-30 parts of a solvent. The preparation method comprises the following steps: taking the graphene, the Fe3O4 nano particles, the Al2O3 nano powder and the CaCO3 according to the component ratio of the graphene-doped anti-radiation coating to mix and adding a solvent to form a component A; adding the defoaming agent, the dispersing agent and the film forming auxiliary into matrix resin and mixing to form a component B; mixing the component A and the component B to obtain the graphene-doped anti-radiation coating. The graphene-doped anti-radiation coating is simple in process and is obvious in anti-radiation effect and does not contain harmful element.

Description

technical field [0001] The invention relates to functional coatings, in particular to a graphene-doped anti-radiation coating and a preparation method thereof. Background technique [0002] With the rapid development of modern science and technology, an invisible and intangible pollution has attracted more and more attention from all walks of life. This is the radiation known as the invisible killer. Radiation includes electromagnetic radiation and ionizing radiation. Electromagnetic radiation has a wide range of wavelengths, from 1×10 -12 m (such as gamma rays) to hundreds of meters (such as radio waves). Ionizing radiation is radiation that causes the ionization of matter, containing enough electromagnetic energy to separate atoms and molecules from tissue and alter chemical reactions in the body. [0003] In principle, electromagnetic protection can be divided into two ways: absorbing and shielding. Pan Zhijun etc. (Chinese patent, a kind of anti-radiation car film, p...
