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 protect the object, decorate or other special functions. UV curing coating is a new type of coating popular in Europe, America, Japan and other places at the end of the 20th century. It was first applied to the surface coating treatment of furniture, floors, mobile phones, walkman shells, etc. Later, its application fields are now further expanded to the fields of cosmetic containers, televisions and computers and other household appliances, motorcycles and overglazing. It has the advantages of not containing volatile organic compounds (VOC), low pollution to the environment, fast curing speed, curing at room t...
