Embodiment 1

[0034] Example 1: Environmentally-friendly electromagnetic shielding paint for interior walls of buildings, which includes the following components by weight: It includes the following components by weight percentage: water-based acrylic resin 20%, conductive mica 60%, graphite 10%, carbon black 7 %, 2% hydroxyethyl cellulose, 1% silicone coupling agent.

[0035] Weigh the water-based acrylic resin, conductive mica, graphite, carbon black, hydroxyethyl cellulose, and silicone coupling agents respectively according to mass percentages; weigh the conductive mica, silicone coupling agent, and hydroxyl Add ethyl cellulose to the water-based acrylic resin and fully stir it with a blender for 20 minutes. In this step, the silicone coupling agent is used to treat the surface of the conductive mica powder; graphite and carbon black are added to the paint separately and fully stirred for 10 minutes; The pre-mixed paint is made 3 times with a three-roller rail machine. The three steel roll...

Abstract

The invention relates to an environment-friendly electromagnetic shielding coating for inner walls of buildings and a preparation method of the environment-friendly electromagnetic shielding coating. The environment-friendly electromagnetic shielding coating is prepared from the following components by weight percentage: 60-80% of conductive powder, 18-30% of waterborne acrylic resin and 2-10% of organic assistant. The preparation method comprises the following steps: firstly, weighing the above components by weight percentage; secondly, adding conductive mica, a chelating agent, an anti-settling agent and a dispersing agent into the waterborne acrylic resin, and fully stirring for 20min by a stirrer; thirdly, adding graphite and carbon black into the coating respectively and fully stirring for 10min; fourthly, rolling the premixed coating by a three-roll machine for three times, dispersing agglomerated graphite and carbon black to be uniformly distributed around the conductive mica and generating extrusion force to enable the conductive ingredients to be combined compactly, so as to form a good conductive network. The environment-friendly electromagnetic shielding coating is safe to use, resources and energy are saved, and environment pollution and public hazard can be reduced; and the preparation method is convenient and easy to operate, and the conductivity is greatly improved.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to an environmentally-friendly electromagnetic shielding coating for internal walls of buildings and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, all kinds of technological products and household appliances are gradually leaving people's lives. All of these have greatly improved people's work efficiency and improved people's quality of life, but they also hurt people at all times. We, because they emit electromagnetic waves at any time. The phenomenon that electromagnetic waves are emitted or leaked into the air is called "electromagnetic radiation". Electromagnetic radiation is divided into strong electromagnetic waves, low frequency waves, and microwaves. Electromagnetic radiation is colorless, tasteless, and invisible. It is ubiquitous in daily life. As long as various household appliances, elevator machine rooms, communicat...
