Abstract

The invention discloses a water-based acrylic emulsion adhesive capable of releasing negative ions. The water-based acrylic emulsion adhesive capable of releasing negative ions is prepared from acrylic acid, iso-octyl acrylate, methyl methacrylate, styrene, anionic emulsifying agent, non-ionic emulsifying agent, initiating agent, pH buffering agent, cross-linking agent, modified nanometer negative ion powder and deionized water. According to the water-based acrylic emulsion adhesive capable of releasing the negative ions, the modified nanometer negative ion powder is grafted to a water-based acrylic adhesive with the chemical method, and the water-based acrylic adhesive capable of releasing negative ions is obtained; the water-based acrylic adhesive can be used for bonding between non-porous materials such as all kinds of cloth and wood and porous materials such as sponges, and pollution caused by an organic solvent adhesive to the environment is eliminated; meanwhile, the negative ions can be further released, the effects of purifying air and eliminating peculiar smell are achieved.

Description

technical field [0001] The invention relates to the technical field of adhesives. More specifically, it relates to a water-based acrylic emulsion adhesive capable of releasing negative ions and a preparation method thereof. Background technique [0002] With the increasing awareness of people's environment and health, the society no longer only pays attention to the adhesive performance of adhesives, and the environmental protection requirements for adhesives are becoming more and more stringent. The development of environmentally friendly green adhesives that meet the three requirements of "environmental protection, health, and safety" has become a reality. It is imperative. At the same time, with the improvement of people's living standards, there is more and more demand for furniture, and the adhesives used in furniture processing, especially synthetic resin adhesives, will bring chemical pollution such as formaldehyde and benzene, which will cause harm to human health. ...
