Embodiment 1

[0019] A flame-retardant modified PET / PTT material, the composition of which is: PET 67%, PTT 20%, E-MA-GMA 3%, BDP 6%, PDMS 2%, nano-silica 1 %, PTFE 0.5%, antioxidant 1010 0.1%, PETS 0.4%, the PTFE is a nano anti-dripping agent polytetrafluoroethylene with a particle size in the range of 0.5-100nm.

[0020] Preparation method: (1) Dry PET and PTT in a forced air circulation oven at 110°C-120°C for 6-8 hours, and set aside; (2) Weigh the dried PTT according to the weight ratio and add it to high-speed mixing At the same time, add the BDP, PDMS, nano-silica, PTFE, antioxidant 1010, and PETS according to the weight ratio, and mix together for 3 to 5 minutes. After being melted, extruded, pelletized, and dried, PTT flame retardant masterbatches were prepared for use; (3) Weighed the dry PET according to the weight ratio and added it to the high-speed mixer, and then added the PET prepared in step (2). PTT flame retardant masterbatch, and add E-MA-GMA according to the weight rat...

Embodiment 2

[0022] A flame-retardant modified PET / PTT material, the composition of which is: PET 43%, PTT 30%, E-MA-GMA 6%, BDP 10%, PDMS 6%, nano-silica 3 %, PTFE 0.5%, antioxidant 1010 0.5%, PETS 1%, the PTFE is a nano anti-dripping agent polytetrafluoroethylene with a particle size in the range of 0.5-100nm.

[0023] The preparation method is the same as in Example 1.

Abstract

The invention discloses a flame-retardant and modified PET / PTT material and a preparation method thereof. The flame-retardant and modified PET / PTT material comprises the following components in mass percentage: 40% to 70% of PET, 20 to 30% of PTT, 3% to 6% of E-MA-GMA, 6% to 10% of BDP, 2% to 6% of PDMS, 1% to 3% of nano silica, 0.1% to 0.5% of PTFE, 0.1% to 0.5% of anti-oxidant 1010, and 0.1% to 1% of PETS. According to the invention, the flame-retardant and modified PET / PTT material is prepared through two steps. In this way, the original advantages of PET and PTT are well maintained, while the flame-retardant and modified PET / PTT material is good in flame-retardant and modified effects. The flame-retardant and modified PET / PTT material completely meets halogen-free, smoke-free, environmentally-friendly, droplet-free and flame-retardation requirements up to the UL94V-0 level. The application field of the flame-retardant and modified PET / PTT material is expanded.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant modified PET / PTT material and a preparation method thereof. Background technique [0002] PET / PTT (polyethylene terephthalate / polytrimethylene terephthalate) is a new type of plastic alloy material, which has excellent molding processing, impact resistance, high temperature heat aging resistance, and chemical resistance. Performance, so it is widely used in automotive, electronic and electrical, fiber and other fields. However, PET / PTT has the defects of poor flame retardancy and unstable mechanical properties, which will greatly limit its application range. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency, halogen-free, droplet-resistant flame-retardant modified PET / PTT material and a preparation method thereof. [0004] The technical solution adopted by the present invention to solve the tech...
