Problems solved by technology

This preparation method is simple in technology, but because the negative ion additive is an inorganic particle, when it is added to a fabric coating agent or a paint system, it is an incompatible system with the main components in the system, and can only be dispersed in the system in the form of particles, thereby Resulting in: 1) the anion agent coating or coating agent has poor stability and poor uniformity, and the agglomeration of the anion agent in the coating agent or coating is serious; The bonding force with the bottom layer, there are problems such as poor coating adhesion
Therefore, solving the problems of poor mixing stability and poor uniformity of the binder and the anion additive will be one of the key issues in the development of anion coatings or coating agents.

Description

technical field [0001] The invention relates to a polyacrylate emulsion, in particular to a polyacrylate composite emulsion with the function of generating negative ions. The invention also relates to the preparation method and application of the polyacrylate composite emulsion with the function of releasing negative ions. Background technique [0002] Since Aschkinass and Caspan affirmed that negative air ions have biological significance in 1902, and since Soviet scholars published a paper on using negative air ions to eliminate germs in 1903, countries around the world have carried out a large number of experimental studies to further affirm the value of negative air ions. [0003] Due to industrial waste discharge, garbage incineration, toxic chemical components, electromagnetic radiation and other pollution, the positive ions in the earth's atmosphere have increased sharply and negative ions have sharply decreased. According to the "International Medical Journal" repor...
