Ultraviolet curing coating containing modified carbon nanotube

Abstract

The invention discloses an ultraviolet curing coating containing a modified carbon nanotube. Raw materials comprise epoxy acrylate prepolymers, reactive diluents, polyimide, modified carbon nanotube montmorillonite, attapulgite, titanium dioxide sol, sulfydryl silane coupling agents, 3, 9-dihydroxytoluene-3', 9'-diethyl-1, 5, 7, 11-tetra-oxygen spiro-heterocycle [5, 5] undecane and auxiliaries. The modified carbon nanotube is prepared according to the process including the steps: adding photo-initiators D2959 and succinic anhydride into methylene dichloride, stirring the materials, adding 4-methylaminopyridine, performing reaction for 8-15 hours at the temperature of 60-65 DEG C, and performing washing, drying and rotary evaporation to obtain a material A; epoxidizing a carbon nanotube toobtain an epoxidized carbon nanotube; blending the epoxidized carbon nanotube, the material A and xylene, stirring the materials, adding triphenyl phosphine, performing reaction for 6-8 hours at the temperature of 85-95 DEG C, and performing rotary evaporation and drying.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to an ultraviolet curing coating containing modified carbon nanotubes. Background technique

[0002] UV-curable coating is a new type of coating. Different from traditional coatings that adopt natural drying or thermal curing processes, this coating undergoes a photochemical reaction after being irradiated by ultraviolet light, so that the coating can be quickly polymerized and cross-linked, so as to achieve curing and film formation. Purpose, it has the characteristics of convenient coating, fast curing speed and less pollution, so it has been widely used in wood, plastic, metal, electronics and other fields. However, when the existing UV-curable coatings are used in fields such as aluminum products, the adhesion is poor, and the hardness is often not high, which limits its application.
