Abstract

The invention relates to cement-based magnetic paint as well as a preparation method and application thereof. The magnetic paint takes cement, quartz sand, glue, magnetic micro-powder and other cheapmaterials as main raw materials and adopts a thickening agent, a water reducing agent, a dispersing agent, a de-foaming agent, a leveling agent and other auxiliaries for formula optimization. Comparedwith common resin-based magnetic paint, the cement-based magnetic paint provided by the invention has the advantages of good aging resistance and flame retardant property; as the main raw materials are the cheap raw materials, the cost of the magnet paint is significantly reduced. The green and environmentally-friendly magnet paint has wide application prospect in the fields of magnetic walls, magnetic glass mats, magnetic sheets and the like.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, and in particular relates to a cement-based enamel and its preparation method and application. Background technique [0002] Magnetic varnishes have many practical uses, but existing magnetic varnishes generally have the problems of poor magnetic properties and high prices. Through searching, it is found that the existing magnetic paint solutions similar to the present invention include "a magnetic paint (CN103409045)", "a magnetic conductive paint and its preparation method and application (CN105295666A)", "under multi-pole static magnetic field The used soft magnetic coating and its preparation method (CN104231708A)". The base materials used in these inventions are more expensive resin materials (CN103409045), low-temperature curing resins (CN105295666A), and adhesives (CN104231708A), which are not economical for the realization of large-area magnetic coatings. In view of this, ...
