Description
Technical Field
The invention belongs to a TPU/dendritic phthalocyanine loaded SiO with a photocatalytic effect2A composite wire and a method for producing the same.
Background
Chinese patent ZL2014108005249 discloses SiO supported by 1-3 generation aryl ether dendritic phthalocyanine complex2Preparation method and application of visible light photocatalyst, and dendritic phthalocyanine supported SiO in patent2Has the advantages of high active oxygen yield, good hydrophilicity, difficult agglomeration, high electron transfer rate and the like, and can be applied to the fields of industrial sewage treatment, dye wastewater degradation and the like. However, solid powdery dendritic phthalocyanine supported SiO2In practical application, the problems of device formation and recycling exist.
3D prints to be a novel intelligent manufacturing technique, compares traditional shaping mode, and its advantage such as quick preparation, meticulous manufacturing, material utilization rate height are received attentions. Fused Deposition Modeling (FDM) is an important component of 3D printing technology, which can form devices with complex structures from materials stacked through fuses, making the materials device.
TPUs, known by the generic name thermoplastic polyurethane elastomers, are block copolymers composed of soft oligomeric polyol segments and hard diisocyanate segments. The TPU not only has good processing performance, oil resistance, ozone resistance and excellent elasticity, but also is a high-transparency material and has high transparency. At present, TPU resin is mainly applied to the fields of sports goods, packaging materials, textile fabrics, building materials and the like, and reports of direct application to the field of 3D printing are few.
Thus, the dendritic phthalocyanine was SiO-supported2The material is blended with TPU resin, and simultaneously water-soluble polymer polyvinyl alcohol (PVA) is added as a pore-foaming agent to prepare a 3D printing wire rod, so that the dendritic phthalocyanine supported SiO is realized on the basis of combining with FDM technology2The device is formed and applied to photocatalytic degradation treatment of organic pollutants in sewage, air and soil.
Disclosure of Invention
Against the background and problems mentioned above, the object of the present invention is to solve the problem of SiO-supported dendritic phthalocyanine2Has the problems of device formation, recycling and the like, takes high-light-transmission resin TPU as a carrier, and provides TPU/dendritic phthalocyanine loaded SiO with photocatalytic effect2A composite wire and a method for producing the same. The composite wire prepared by the invention has good light transmission and visible light photocatalysis performance, the preparation method is simple and efficient, and the composite wire can be applied to photocatalytic degradation treatment of organic pollutants in sewage, air and soil.
The purpose of the invention is realized by the following technical scheme:
TPU/dendritic phthalocyanine loaded SiO with photocatalytic effect2The composite wire is characterized by being prepared from the following components in percentage by weight:
TPU 55-75
PVA 5-25
SiO supported by 1-3 substituted aryl ether dendritic phthalocyanine complex25-20
2-8 parts of plasticizer
