Embodiment

[0022] In order to facilitate the addition of nano-graphene in coatings and inks and to avoid the accumulation of graphene particles during storage and use, the present embodiment will have a particle size of 20-40nm ultrafine nano-graphene particles loaded on the wax of particle size 200-800nm A dispersion is formed on the particles. There are two types of wax pastes: oily and water-based wax pastes.

[0023] The present embodiment loads nano-graphene oily and water-based wax slurry and is prepared according to the following steps:

[0024] 1. Preparation of carrier wax slurry

[0025] It is used to prepare carrier wax slurry into oily wax slurry and water-based wax slurry. The oily wax slurry in this embodiment adopts polyethylene wax mixed with 20% polytetrafluoroethylene wax, and the water-based wax slurry adopts an acid value of 18mgKOH / g and a penetration of 1.5 mm of oxidized polyethylene wax.

[0026] 1.1 Preparation of oily wax slurry

[0027] The dispersion used ...

Abstract

The invention belongs to the technical field of fine chemical engineering polymer materials, and specifically relates to nano-graphene loaded wax liquor, and a preparation method and a use thereof. The wax liquor is a wax dispersion which is formed by loading ultrafine nano-graphene particles having the particle size in the range from 20 to 40 nm on wax particles having the particle size in the range from 200 to 800 nm; and the total solid content of the wax liquor is 15-25%. The preparation method provided by the invention is used for successfully solving the dispersion and aggregation problems of graphene while being used for a paint or an ink body; and the nano-graphene loaded wax liquor prepared by the preparation method is used for paint, ink or leather finishing, and has the effects of rub resistance, static resistance and electromagnetic wave blocking.

Description

technical field [0001] The invention belongs to the technical field of fine chemical polymer materials, and in particular relates to a wax slurry loaded with nanometer graphene, a preparation method and application thereof. Background technique [0002] Graphene has a very high specific surface area, super thermal and electrical conductivity, high strength and self-lubricating properties. Recently, remarkable achievements have been made in the preparation and application of graphene, and the preparation technology has been popularized. [0003] The use of wax emulsions or wax dispersions in coatings and inks is a well established technique. [0004] The use of graphene in coating and ink systems presents dispersion and aggregation challenges. At present, the wax slurry technology of nano-graphene loading for coatings and inks has not been reported. Contents of the invention [0005] The object of the present invention is to address above-mentioned situation, and propose...
