▎ 摘 要
NOVELTY - A superhydrophilic nano coating comprises 3-8 pts. wt. epoxy resin, 6-9 pts. wt. isopropyl silicate, 15-20 pts. wt. N- beta -(aminoethyl)- gamma -aminopropylmethyldimethoxysilane, 0.8-1.2 pts. wt. latent dicyandiamide curing agent, 0.5-2 pts. wt. nano white graphene, 0.1-0.5 pt. wt. nano scale graphene powder, 15-25 pts. wt. cyclohexane and 15-25 pts. wt. ethanol. USE - Superhydrophilic nano coating of heat pipe such as sintered heat pipe or micro-grooved heat pipe (all claimed) for cooling equipment. ADVANTAGE - The non toxic and environmentally-friendly superhydrophilic nano coating has excellent hydrophilic performance and excellent heat dissipation effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of superhydrophilic nano coating, which involves (1) weighing the raw materials, (2) dripping N-beta-(aminoethyl)-gamma-aminopropylmethyldimethoxysilane in ethanol, stirring for 0.5 hour at room temperature, distilling off ethanol under reduced pressure, (3) heating epoxy resin and melting, adding isopropyl orthosilicate, continuously heating at 150-155 degrees C for 2 hours, heat-preserving at 150-155 degrees C for 3-4 hours, cooling to room temperature, (4) adding latent dicyandiamide curing agent, nano white graphene, nano graphene powder, cyclohexane and remaining ethanol and stirring to obtain final product; and #heat pipe, which is provided with housing and capillary core. The fine core wall is coated with the superhydrophilic nano coating layer formed by super hydrophilic nano coating.
