Abstract

The invention discloses a synthetic method of high-performance mesoporous nano TiO2 as well as application thereof in latex paint, which belongs to the technical field of nano TiO2. The synthetic method comprises the following steps: adding deionized water and glacial acetic acid into absolute ethyl alcohol to prepare a mixed solution; successively dropwise adding tetrabutyl titanate TBOT solution, polyethyleneglycol 400 and cetyl trimethyl ammonium bromide CTAB into the mixed solution in a stirring process, forming a sol system, placing the sol system into a hydrothermal reaction kettle to perform the hydrothermal reaction, obtaining precursor precipitates, successively centrifugally washing, drying and roasting the precursor precipitates, and obtaining the mesoporous nano TiO2 having anordered mesoporous passage. The prepared mesoporous nano TiO2 has high reinforcing performance and high catalytic activity. When the mesoporous nano TiO2 is applied to latex paint, the stability of alatex paint film is improved, a high effect for killing bacteria in indoor air can be realized, the latex paint has a lasting efficacy for resisting bacteria and killing the bacteria, and the indoor hygienic condition is effectively improved.

Description

technical field [0001] The invention belongs to nano TiO 2 In the field of production technology, involving high-efficiency mesoporous nano-TiO 2 Synthetic method and its application in latex paint. Background technique [0002] Environmental protection issues in today's era have attracted much attention, and it is particularly important for the indoor environment purification of people's long-term life. Water-based paints use water as a solvent instead of organic solvents in organic paints, which can effectively reduce the damage caused by the volatilization of harmful organic compounds to the human body, and can also absorb and degrade VOCs volatilized by other indoor objects, and kill indoor bacteria. Provides an environmentally friendly and hygienic indoor environment for daily life, work and study. So improving the formula or modifying active components of water-based paints has become a hot topic in the research of water-based paints. It is difficult for ordinary la...
