Nano TiO2 composite water treatment material and preparation method thereof

Abstract

The invention discloses a nano TiO2 composite water treatment material and a preparation method thereof, and relates to a nano composite water treatment material and a preparation method thereof. The material solves the problem that the nano TiO2 photocatalytic performance of the nano TiO2 composite water treatment material and the original properties of other materials compounded with nano TiO2 are greatly reduced because the conventional nano TiO2 composite water treatment material is obtained by adopting a blending technology; and the invention provides a mature nano TiO2 composite water treatment material preparation method capable of preserving the properties of the nano TiO2 and a composite matrix material. The nano TiO2 composite water treatment material is prepared from a siloxane polymer and TiO2 sol. The preparation method comprises the following steps of: 1, preparing the TiO2 sol; and 2, adding the siloxane polymer into the TiO2 sol, soaking, stirring, cooling, and thus forming a composite polymer by the TiO2 and the siloxane. The nano TiO2 siloxane composite water treatment material can be applied in the field of deep treatment of water.

Description

technical field [0001] The invention relates to a nanocomposite water treatment material and a preparation method thereof. Background technique [0002] Nano-TiO 2 It has a photocatalytic effect and can degrade organic matter in water into inorganic matter, so it has been widely used in the field of water treatment. Since nanomaterials are difficult to recycle in the water treatment process, they must be compounded with other materials before use. Currently, nano-TiO 2 The compounding with other materials is only at the level of simple blending. Due to the current use of blending technology to obtain nano-TiO 2 Composite water treatment materials whether nano-TiO 2 Photocatalytic performance, or with nano-TiO 2 The original properties of other materials to be compounded are greatly reduced. [0003] Moreover, the nano-TiO at the present stage 2 The preparation and research of composite water treatment materials mainly rely on experimental exploration and experience, ...
