Embodiment 1

[0070] Example 1 Glass beads loaded modified Nano-TiO 2 Preparation of photocatalysts

[0071] S01. Add 1.5kg of nano-titanium dioxide to 100L of deionized water, add 0.08kg of surfactant sodium dodecyl sulfate (SDS) and 0.1kg of dispersant triethanolamine at the same time, after 800-1000r / min high-speed shearing for 15min, add 60kg of glass microspheres were stirred evenly and then ultrasonically dispersed for 15 minutes to obtain a mixture.

[0072] S02. After leaving the mixture obtained in step S01 for 24 hours, place the mixture in an oven at 50°C for dehydration and drying, and pass through a 0.1mm round hole sieve to form glass beads loaded modified Nano-TiO 2 of photocatalysts.

Embodiment 2

[0073] Example 2 Modified Nano-TiO supported by glass microspheres 2 Preparation of photocatalysts

[0074] S01. Add 1.0kg nano titanium dioxide to 100L deionized water, add 0.07kg surfactant sodium dodecyl sulfate (SDS) and 0.08kg dispersant triethanolamine at the same time, after 800~1000r / min high-speed shearing for 15min, add 60kg of glass microspheres were stirred evenly and then ultrasonically dispersed for 15 minutes to obtain a mixture.

[0075] S02. After leaving the mixture obtained in step S01 for 24 hours, place the mixture in an oven at 50°C for dehydration and drying, and pass through a 0.1mm round hole sieve to form glass beads loaded modified Nano-TiO 2 of photocatalysts.

Embodiment 3

[0076] Example 3 Modified Nano-TiO supported by glass microspheres 2 Preparation of photocatalysts

[0077] S01. Add 2.0kg of nano titanium dioxide to 100L of deionized water, add 0.08kg of SDS surfactant and 0.1kg of triethanolamine dispersant at the same time, after 800~1000r / min high-speed shear for 15min, add 80kg of glass beads and stir evenly before continuing to sonicate Disperse for 15 minutes; a mixture was obtained.

[0078] S02. After leaving the mixture obtained in step S01 for 24 hours, place the mixture in an oven at 50°C for dehydration and drying, and pass through a 0.1mm round hole sieve to form glass beads loaded modified Nano-TiO 2 of photocatalysts.

Abstract

The invention discloses a glass bead modified Nano-Tio2 photocatalyst, application thereof to a formaldehyde removal magnesium oxide board and the formaldehyde removal magnesium oxide board. The photocatalyst is obtained by dispersing, dewatering and dying from a nanometer titania aqueous solution, a surfactant, a dispersant and glass beads in an appropriate ratio. By applying the photocatalyst to the preparation of formaldehyde removal magnesium oxide board, the magnesium oxide board obtained has the effect of enduringly purifying formaldehyde, and has the advantages of good thermo insulating property and good screw holding capability, without moisture absorption, active magnesia and buckling deformation.

Description

technical field [0001] The invention relates to the technical field of decorative materials, more specifically, to a glass microbead-loaded modified Nano-TiO 2 Photocatalysts and their application in aldehyde-removing glass magnesium boards and aldehyde-removing glass magnesium boards. Background technique [0002] With the development of the economy and the improvement of living standards, people are more and more advocating the comfortable, high-end and intelligent office and living environment, which has led to the upsurge of decoration and the modernization of indoor facilities. However, the promotion of new construction, decoration materials and the use of more household chemicals have caused serious indoor air pollution, even much worse than outdoor air pollution. With the continuous increase of residential buildings and the popularization of indoor entertainment equipment such as TV, modern people spend more time working, studying and living indoors. The time is lon...
