Abstract

The invention discloses a PETG / dendritic phthalocyanine-loaded SiO2 composite wire with a photocatalytic effect, and a preparation method thereof. According to the present invention, the PETG / dendritic phthalocyanine-loaded SiO2 composite wire with the photocatalytic effect, and the preparation method thereof are provided by using the high light-transmitting resin PETG as the carrier; the technical scheme comprises that the components of the formula comprise, by mass, 50-70 parts of PETG, 10-30 parts of PVA, 5-20 parts of 1-3 generation aryl ether dendritic phthalocyanine coordination compoundloaded SiO2, 3-10 parts of a plasticizer, 2-5 parts of a stanilizer, and 0.5-2 parts of a dispersant, and the preparation method comprises: drying, weighing, mixing, carrying out melt extrusion granulation, and carrying out extrusion shaping winding; the prepared PETG / dendritic phthalocyanine-loaded SiO2 composite wire has good light transmittance and good visible light photocatalytic performance; the preparation method is simple and efficient; and the the prepared PETG / dendritic phthalocyanine-loaded SiO2 composite wire can be used for the photocatalytic degradation treatment of organic pollutants in sewage, air and soil.

Description

technical field [0001] The invention belongs to a PETG / dendritic phthalocyanine loaded SiO with photocatalytic effect 2 Composite wire and method for its preparation. Background technique [0002] Chinese patent ZL2014108005249 discloses a 1-3 generation aryl ether dendritic phthalocyanine complex loaded SiO 2 Preparation method and application of visible light photocatalyst, dendritic phthalocyanine-supported SiO described in the patent 2 It has the advantages of high active oxygen production rate, good hydrophilicity, not easy to agglomerate and high electron transfer rate, and can be used in industrial sewage treatment, degradation of dye wastewater and other fields. However, solid powder dendritic phthalocyanine loaded SiO 2 There are problems of deviceization and recycling in practical applications. [0003] 3D printing is a new type of intelligent manufacturing technology. Compared with traditional molding methods, it has attracted much attention for its advantages...
