Abstract

The invention discloses a negative ion functional impregnating glue and a preparation process thereof, and applications in preparation of plate decoration surface materials, wherein the negative ion functional impregnating glue comprises a glue mixed with negative ion powder, and the negative ion powder is tourmaline powder loading nanometer titanium dioxide and a rare earth oxide. According to the present invention, tourmaline powder is used as the matrix material, and nanometer titanium dioxide and a rare earth oxide are loaded on the surface of the tourmaline particles, wherein the nanometer titanium dioxide and the rare earth oxide can perform surface modification on the tourmaline powder, such that the tourmaline powder has the excellent dispersion stability in the organic polymer resin colloid so as to ensure the comprehensive performance of the product; and the nanometer titanium dioxide and the rare earth oxides can release air negative ions, and synergistically act with the tourmaline powder so as to improve the negative ion release of the product and reduce the adding amount of the negative ion powder in the colloid, such that the cost is saved, and the excellent dispersion stability of the negative ion powder in the colloid is ensured.

Description

technical field [0001] The invention belongs to the technical field of negative ion functional plate manufacturing, and in particular relates to a negative ion functional impregnating glue, its preparation process and its application in the preparation of plate facing materials. Background technique [0002] The building materials used in interior decoration contain more or less various volatile organic compounds, which will cause great pollution to indoor air and endanger human health. After the negative air ion technology is applied to the particleboard, the particleboard will release negative air ions during use, and the negative air ions can make the living biological cells negatively charged, so that the biological cells have the ability to resist virus attack. [0003] The Chinese invention patent with the authorized notification number CN 104339430 B discloses a particleboard for environment-friendly decoration, which is composed of an anion adhesive layer and a first...
