Abstract

The invention discloses bio-magnetic nano-paint and a preparation method thereof. The bio-magnetic nano-paint comprises the following raw materials in parts by weight: 15-30 parts of polymer emulsion, 7-10 parts of hyperbranched polyester alkyd resin, 1-2 parts of graphene oxide, 5-8 parts of cationic segmented copolymers, 10-25 parts of butyl cellosolve, 1-2 parts of nano-ferroferric oxide, 0.5-0.8 parts of carbonyl iron, 0.5-0.8 parts of nano-lanthanum trioxide, 1-3 parts of silicon dioxide aerogel, 0.1-0.3 parts of a wetting and dispersing agent, 21-25 parts of ground calcium carbonate and 0.2-0.4 parts of a defoaming agent. The bio-magnetic nano-paint disclosed by the invention is environment-friendly paint with excellent water resistance and scrubbing resistance and has a good anti-electromagnetic radiation function, and the electromagnetic pollution to the environment is reduced; an absorption band of the paint is wider than that of a common metal shielding material.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a biomagnetic nano coating and a preparation method thereof. Background technique [0002] At present, with the continuous breakthrough and development of computer network technology worldwide, the network has spread all over every corner of our lives, such as mobile phones and laptops we use every day, but correspondingly, we have also pushed ourselves into a Go in an environment full of radiation and pollution. While modern equipment brings us convenience, it also continuously enhances the electromagnetic radiation around us. The pollution produced by electromagnetic radiation will not only interfere with the normal operation of electronic equipment, but also affect human health and ecological balance. The use of electromagnetic shielding materials for electromagnetic shielding protection is the most effective means of protection in daily work and life. [0003] Biomass energy is a k...
