preparation example Construction

[0020] according to figure 1 Shown, the preparation method of a kind of graphene nano-material automobile finish of the present invention, the method has the following steps:

[0021] 1) Preparation of graphene powder;

[0022] Concentrated H was added to the graphite in a certain proportion 2 SO 4 , KMnO 4 , H 2 0 and H 2 o 2 Wait for reagents, mix evenly and maintain a certain temperature and time, then add dilute HCl to wash and stand still, take out the precipitate, wash to neutral, dry, expand and restore, and finally get black nano-graphene powder;

[0023] 2) Preparation of nano-graphene slurry;

[0024] Add nano-graphene powder into the solution of absolute ethanol and dispersant and stir, adjust to a suitable pH value, and finally use high-speed disperser and ball mill to disperse for a certain period of time to obtain nano-graphene dispersion;

[0025] 3) Preparation of graphene nanomaterial automotive topcoat;

[0026] The raw material nano-graphene slurry,...

Embodiment

[0031] Step 1: preparation of graphene powder;

[0032] Mix 50.0g graphite with 1-5L 98% H 2 SO 4 Mix and stir well at 20 0 Slowly add 150.0-300.0g KMnO at C 4 , maintained for 12-24h, and then added a certain amount of H 2 0, the temperature and time were maintained at 80-90 0 C, 0.5-1h, then add 250-500ml H 2 o 2 (concentration 30%), finally with HCl and H 2 Wash with O, take the precipitate to neutrality, dry, expand and reduce at high temperature, and obtain black nano-graphene powder. (The above ratio can be scaled up in equal proportions)

[0033] Step 2: preparation of nano-graphene slurry;

[0034] First, mix absolute ethanol and dispersant evenly, then add nano-graphene powder into it, stir at a certain speed, add a pH regulator to adjust to a suitable pH value, and finally use a high-speed disperser and a ball mill to disperse for a certain period of time A nano-graphene dispersion is obtained, wherein the nano-graphene powder is the nano-powder prepared in...

Abstract

The invention relates to a preparation method of a graphene nanometer material automobile finish. The method combines a novel graphene nanometer material with a traditional automobile finish material to successfully develop a new high-class automobile paint. The graphene nanometer material is composed of graphene slurry, a film forming substance, a color filler, a curing agent, a catalyst and an auxiliary agent; the components are mixed in proportion to interact with each other so as to generate the graphene nanometer material automobile finish. The process is unique, the quality is excellent, the excellent thermal, mechanical and optical properties of the graphene nanometer material are integrated, and super-high thermochemical stability, mechanical property and light transmission property (97.7%) are achieved. The prepared automobile finish has the characteristics of high strength, ultraviolet resistance, oxidization resistance, transparent property, good adhesion, scratch resistance, acid resistance and alkali resistance.

Description

technical field [0001] The invention relates to a preparation method of a graphene-based automobile topcoat. A new generation of advanced automotive coatings developed successfully by using new graphene nanomaterials combined with automotive topcoat raw materials to replace traditional, single automotive topcoats. Background technique [0002] In 2004, graphene was first discovered by a research team led by Professor Andre Geim of the University of Manchester, for which it won the 2010 Nobel Prize in Physics. Graphene is the most ideal, thinnest, hardest and softest two-dimensional nanomaterial in the world. Graphene has excellent electrical, optical, thermal and mechanical properties, and has extremely high stability, which has aroused great interest in the scientific and industrial circles. Based on its high light transmittance, extremely high conductivity, ultra-wide light absorption range (far infrared to ultraviolet), and extremely high thermal and chemical stability,...
