Abstract

Water-based acrylic acid paint utilizing negative ions to purify air is disclosed. 1-5% by weight of a negative ion paint additive is added into water-based acrylic acid paint. The additive is prepared by modifying negative ion powder and activated carbon powder with a titanate coupling agent. According to the provided water-based acrylic acid paint utilizing the negative ions to purify air, the titanate coupling agent is adopted to modify tourmaline in the negative ion powder and the negative ion powder is composited with the activated carbon powder, and therefore surface hydrophobicity of the tourmaline is improved, the crystal structure of the tourmaline is not destroyed, original physical characteristics of the tourmaline are not influenced, and negative ion release of the tourmaline is improved than negative ion release of tourmaline treated with a traditional silane coupling agent, thus improving air quality.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-based acrylic coating which utilizes negative ions to purify air. Background technique [0002] Building materials can easily threaten and damage the living environment and living environment of human beings. Improper use of building materials, performance and functional limitations, all of which may have a negative impact on the indoor environment in which humans live. In recent years, with the improvement of the quality of life, people are more and more aware of this problem. Modern science believes that indoor air ion concentration is an important indicator to measure indoor comfort. Negative ion paint is a paint with negative ion additives added to the paint. The negative ion paint quickly releases a large number of negative ions after painting, which can effectively reduce the formaldehyde, VOC and dust content in the indoor air, kill bacteria, and remove odors; i...
