Problems solved by technology

[0004] However, the existing electrothermal coatings have the disadvantage that the coating is easily damaged, which seriously restricts the wide application of electrothermal coatings.
At the same time, as a wall or floor coating used to beautify the interior, the coating formed by the electrothermal coating is prone to scratches or cracks. After the coating film is scratched, it cannot achieve self-healing and damage the indoor appearance.

Abstract

The invention relates to a self-healing building inner wall electric-heating coating and belongs to the field of building materials. The coating includes following components: 10-20 parts of acrylic resin, 4-6 parts of epoxy propane, 1.5-3 parts of chitosan, 15-20 parts of graphite powder, 0.5-1.5 parts of nano silicon dioxide, 2-3 parts of active carbon nitrile polyvinyl chloride fiber, 0.5-1 part of acetic anhydride, 1-6 parts of diatomite, 1-3 parts of pigments, 2-4 parts of mica powder, 1-2 parts of an adhesion enhancing agent, 1-5 parts of a dispersing agent and 0.1-1 part of a flame-retarding agent. The coating is suitable for heating of building inner walls and has a self-healing function, by which scratched wall body or floor coatings can be repaired automatically. Meanwhile, the electric-heating coating is added with bio-enzyme which can adsorb formaldehyde, so that the coating can adsorb harmful gases in room, thereby purifying air. Meanwhile, by means of the electric-heating means, the activity of the bio-enzyme in the coating achieves a maximum value, thereby quickly removing the harmful gases in room.

Description

technical field [0001] The invention relates to a self-healing electric heating coating for building interior walls, which belongs to the field of building materials. Background technique [0002] Heating energy consumption in winter is the main energy consumption of Chinese buildings, and people's requirements for building energy conservation are constantly increasing. At present, the heating methods commonly used in my country are mainly radiators such as floor heating, radiators, etc., and radiant heating systems such as infrared electric heating films. Since the heat distribution of the electrothermal coating is more uniform, the thermal effect on the human body and other objects is more efficient, and it has a good market prospect. [0003] At present, several patents of electrothermal coatings are disclosed on the market. They mainly use carbon powder and graphite as fillers, such as an electrothermal coating (CN 102086330A), which is coated on indoor walls, desks, an...
