Problems solved by technology

[0005] To sum up, the problems existing in the prior art are: the graphene in the current heat dissipation coating has not been modified, and the compatibility with the resin system is not good, resulting in loose coating and low strength, and the graphene itself is easy to agglomerate. Loss of thermal conductivity, resulting in poor thermal conductivity and heat dissipation

preparation example Construction

[0056] Such as figure 1 As shown, the preparation method of the graphene-containing UV radiation curable heat dissipation coating provided by the embodiment of the present invention includes the following steps:

[0057] S101: Clean the mixing tank, add UV radiation curing resin, monomer, and mixed solvent in sequence;

[0058] S102: Stir at medium speed of 300RPM-900RPM for 10min-30min, until the resin and monomer are completely dissolved;

[0059] S103: Add photoinitiator and other additives in sequence;

[0060] S104: 300RPM-900RPM medium speed stirring for 10min-30min, until completely dispersed and uniform;

[0061] S105: Under 50RPM-300RPM low-speed stirring, slowly add the thermally conductive filler, after it is completely submerged in the solution, stir at 600RPM-1500RPM for 10-30min at high speed until the thermally conductive filler is evenly dispersed;

[0062] S106: Under 50RPM-300RPM low-speed stirring, slowly add modified graphene (or modified graphene oxide). After it is...

Abstract

The invention belongs to the technical field of heat dissipation materials, and discloses UV radiation curing heat dissipation paint containing graphene and a preparation method of the paint. The paint comprises, by weight, 30-70% of UV radiation curing resin and monomers, 30-70% of mixed solvent, 0.1-5% of photoinitiator, 0.1-5% of auxiliary agent, 1-30% of heat-conducting filler and 0.1-5% of modified graphene or modified graphene oxide. The method comprises the steps that the UV radiation curing resin and monomers and the mixed solvent are added and stirred at a medium speed till the resinand the monomers are dissolved; the photoinitiator and other auxiliary agents are sequentially added and stirred to be dispersed; under the condition of stirring, the heat-conducting filler is added,and after being immersed in the solution, the filler is stirred till the heat-conducting filler is dispersed; under the condition of stirring, the modified graphene or the modified graphene oxide is added, and after being immersed in the solution, the modified graphene or the modified graphene oxide is stirred till the graphene is dispersed; ultrasonic dispersion is conducted till the graphene isdispersed; the product is subpackaged in containers respectively. The overall strength of a coating is improved, agglomeration of the graphene is avoided, and excellent heat conduction capability is provided.

Description

Technical field [0001] The invention belongs to the technical field of heat dissipation materials, and in particular relates to a UV radiation curing heat dissipation paint containing graphene and a preparation method thereof. Background technique [0002] Coating refers to a liquid or solid material that is coated on the surface of an object to form a continuous film and play a role in protecting, decorating or having other special functions on the object. UV curing paint is a new type of paint popular in Europe, America, Japan and other places at the end of the 20th century. It was first used in the surface coating treatment of furniture, floors, mobile phones, Walkman casings, etc. Later, its application areas have been further expanded to the fields of cosmetic containers, household appliances such as televisions and computers, and other fields such as motorcycles and varnishing. It has the advantages of containing no volatile organic compounds (VOC), causing little env...
