Embodiment Construction

[0004] As a common polymer material, polyurethane (PU) has good flexibility and high elastic modulus. Using silane coupling agent to introduce specific functional genes to improve nano-TiO 2 The surface properties of the polyurethane film as a carrier, made of TiO 2 -Polyurethane composite photocatalytic material. Its preparation method and principle: TiO 2 Photocatalytic technology due to the presence of nano-TiO 2 Difficult to recycle, high operating cost and residual TiO 2 Problems such as environmental pollution have greatly limited its practical application process. Nano-TiO 2 For immobilization, is the solution to the nano-TiO 2 An efficient way to recycle the problem. At present, the carrier materials used are mainly ceramics, stainless steel materials, hollow glass beads, etc., but ceramics and hollow glass are easy to break, and stainless steel materials have a large specificity, which limits the scope of application of these materials and is difficult for indus...

The invention is used for the load type photocatalytic material and the preparation method thereof.

Description

Technical field: [0001] The invention relates to a water treatment material, in particular to a loaded photocatalytic material and a preparation method thereof. Background technique: [0002] TiO 2 It has a strong photocatalytic effect and has a strong photocatalytic degradation effect on many harmful substances in sewage, so it is widely used in sewage treatment, but due to TiO 2 Environmental pollution and recycling difficulties restrict TiO 2 application in practice. To solve the recovery of TiO 2 problem, using an appropriate carrier for nano-TiO 2 be immobilized to solve TiO 2 The key research direction of recycling, the carrier materials that have been used at present include ceramics, stainless steel, hollow glass beads, etc. Ceramic and glass hollow balls are fragile, and stainless steel has a large specificity and is expensive, making it difficult for industrial application. Invention content: [0003] The object of the present invention is to provide a load...
