Embodiment 1

[0023] Mix 30 parts of acrylic resin, 10 parts of graphene, and 60 parts of water into the blender, control the speed at 2000 rpm, and stir for 2 hours; add 15 parts of aluminum nitride, 10 parts of silicon carbide, 5 parts of carbon nanotubes, carboxymethyl 4 parts of sodium cellulose, 4 parts of polydimethylsiloxane, 4 parts of ethylenediamine, 4 parts of polyether modified polydimethylsiloxane, 4 parts of aminopropyl trimethoxysilane, control The rotation speed is 2000rpm, and the stirring time is 3h; the above mixture is put into a sand mill to grind and disperse for 1h, and the graphene heat dissipation coating is obtained.

Embodiment 2

[0031] Mix 30 parts of acrylic resin, 1 part of graphene, and 30 parts of water into the mixer, control the rotation speed at 1000 rpm, and stir for 1 hour; add 15 parts of aluminum oxide, 5 parts of carbon black, and 2 parts of sodium carboxymethyl cellulose to the mixer in sequence. 2 parts, 2 parts of polydimethylsiloxane, 2 parts of ethylenediamine, 2 parts of polyether modified polydimethylsiloxane, 2 parts of aminopropyl trimethoxysilane, control the speed of 1000rpm, stirring time 1h; add the above mixture into a sand mill to grind and disperse for 1h to obtain a graphene heat dissipation coating.

[0032] Comparative example 1, this comparative example is basically the same as Example 1, but heat dissipation coating is prepared without adding graphene. Mix 30 parts of acrylic resin and 30 parts of water into the blender, control the speed at 1000 rpm, and stir for 1 hour; add 15 parts of aluminum oxide, 5 parts of carbon black, 2 parts of sodium carboxymethyl cellulose...

Embodiment 3

[0039] Mix 40 parts of acrylic resin, 5 parts of graphene, and 35 parts of water into the mixer, control the rotation speed at 1500 rpm, and stir for 1.5 hours; add 10 parts of aluminum nitride, 5 parts of magnesium oxide, 5 parts of carbon nanotubes, and carboxylate to the mixer in sequence. 3 parts of sodium methylcellulose, 3 parts of polydimethylsiloxane, 3 parts of ethylenediamine, 3 parts of polyether modified polydimethylsiloxane, 3 parts of aminopropyl trimethoxysilane, The rotation speed is controlled at 1500rpm, and the stirring time is 2h; the above mixture is put into a sand mill to grind and disperse for 1h, and the graphene heat dissipation coating is obtained.

Abstract

The invention relates to the technical field of novel coating preparation and in particular relates to an aqueous coating with high heat-dissipation performance which comprises the following components: 30-60 parts of aqueous resin, 1-10 parts of graphene, 10-30 parts of packing, 10-20 parts of an aid and 30-60 parts of a solvent, wherein the radial size of the graphene is 1-100 microns; and the graphene consists of 1-3 layers. The high heat-dissipation performance aqueous coating provided by the invention is good in heat dissipation effect, environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to the technical field of novel paint preparation, in particular to a water-based paint with high heat dissipation performance and a preparation method thereof. Background technique [0002] With the promulgation of environmental protection regulations in various countries and the gradual enhancement of people's awareness of environmental protection, traditional solvent-based coatings have gradually withdrawn from the historical stage due to their high VOC (volatile organic compound) emissions. Environmentally friendly coatings are favored by everyone, and the development of green and environmentally friendly coatings has gradually become the development trend of future coating technology. Among them, water-based coatings stand out with their excellent comprehensive properties. Water-based paint is a kind of paint with water as a solvent. It has the advantages of odorless, non-toxic, non-polluting, low cost, and convenient constr...
