Abstract

The invention discloses a highly flame retardant and aging resistant PET / PTT (polyethylene terephthalate / polytrimethylene terephthalate) alloy. The PET / PTT alloy comprises the following components by mass percent: 30 percent to 70 percent of PET, 15 percent to 30 percent of PTT, 2 percent to 4 percent of E-MA-GMA (ethylene-methyl acrylate-glycidyl methacrylate), 6 percent to 10 percent of flame retardant, 2 percent to 4 percent of flame retardant synergist, 5 percent to 15 percent of modified calcium carbonate, 0.5 percent to 3 percent of nano-silica, 0.5 percent to 2 percent of light stabilizer, 0.1 percent to 0.5 percent of antioxidant and 0.1 percent to 1 percent of lubricant, wherein the modified calcium carbonate is heavy calcium carbonate nano particles with surfaces being treated by an aluminum-titanium composite coupling agent and a particle size being 10-80 nm. The PET / PTT alloy disclosed in the invention has the beneficial effects of original advantages of PET and PTT, significantly improved strength, stiffness, heat resistance, flame retardancy and aging resistance. The limit oxygen index of the PET / PTT alloy is up to more than 35 percent, and the application effect and application field of the PET / PTT is greatly improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high flame-retardant and aging-resistant PET / PTT alloy. Background technique [0002] PET (polyethylene terephthalate) / PTT (polytrimethylene terephthalate) is a new type of plastic alloy, which has excellent molding processing, impact resistance, high temperature heat aging resistance, chemical resistance, etc. Excellent performance, so it has broad application prospects in the fields of automobiles, electronic appliances, home appliances, mechanical components, etc. However, unmodified PET / PTT has the problems of poor flame retardancy, unstable mechanical strength, and poor aging resistance, which will greatly limit its application effect and application field. In order to improve performance, it is often necessary to add a third component to PET / PTT in order to improve performance and expand the scope of application. Contents of the invention [0003] The object...
