Abstract

The invention discloses a method for preparing formaldehyde removal PET / PTT (polyethylene glycol terephthalate / polytrimethylene terephthalate) alloy. The formaldehyde removal PET / PTT alloy comprises, by weight, 50-60 parts of PET, 10-30 parts of PTT, 2-5 parts of SMA (styrene maleic anhydride), 5-6 parts of MBS (methyl methacrylate), 1-5 parts of diatomaceous earth / antibacterial composites, 1-3 parts of diatomaceous earth / inorganic oxide, 0.5-2 parts of nanometer silicon dioxide, 0.1-0.5 part of antioxidants and 0.1-1 part of lubricants. The surfaces of the diatomaceous earth / antibacterial composites are treated by coupling agents, and the surfaces of the diatomaceous earth / inorganic oxide are treated by coupling agents. The method has the advantages that diatomaceous earth / antibacterial composite materials and the diatomaceous earth / inorganic oxide are reasonably matched with one another, synergistic effects are realized by functional additive, accordingly, the formaldehyde removal PET / PTT alloy is excellent in antibacterial, anti-formaldehyde and deodorization characteristics, multifunctional requirements can be met, and application of the formaldehyde removal PET / PTT alloy further can be expanded.

Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to a preparation method of a formaldehyde-removing PET / PTT alloy. Background technique [0002] PET / PTT alloy has excellent physical and chemical properties and high processing performance. It retains the advantages of PET and PTT. At the same time, it has excellent molding processing, impact resistance, high temperature aging resistance, chemical resistance and other excellent properties; but with the progress of society, People have put forward higher requirements for traditional PET / PTT alloys, such as antibacterial performance, aldehyde removal, and deodorization. However, the existing alloys have a single function and their performance needs to be improved, which largely limits PET / PTT alloys. The scope of application of PTT alloy. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of formaldehyde-removing ...
