Problems solved by technology

[0004] Polyethylene terephthalate (PET) has excellent mechanical properties and dimensional stability, and its long-term use temperature can reach 120°C. Decomposition will occur under the action of steam, and due to the high density of benzene rings, the crystallization rate is slow, molding processing is difficult, and the impact performance is poor

Abstract

The invention relates to a polyethylene glycol terephthalate composition and a preparation method thereof. The polyethylene glycol terephthalate composition is prepared from the following raw materials: polyethylene glycol terephthalate and polyethylene glycol terephthalate, the composite material is prepared from polyethylene glycol terephthalate A resin, polyethylene glycol terephthalate B resin, ethylene-octene copolymer grafted glycidyl methacrylate, hollow glass beads, polyhedral oligomeric silsesquioxane polymer, titanate coupling agent, polytetrafluoroethylene resin, hyperbranched polyester polymer, erucyl amide, N, N-dimethylformamide, N-dimethylacetamide, N-dimethylacetamide, N-dimethylacetamide, N-dimethylacetamide, N-dimethylacetamide and the like. According to the invention, N,N '-bis (2, 2, 6, 6-tetramethyl-4-piperidyl)-1, 3-benzenedicarboxamide and bis (2, 6-di-tert-butyl-4-methylphenyl) pentaerythritol diphosphate are used as raw materials. The polyethylene glycol terephthalate composition has excellent mechanical properties, processability and low dielectric constant, and can be applied to shells, cladding and protective materials and the like of 5G base stations,micro base station systems, data communication terminals, antennas and radio frequency modules.

Description

technical field [0001] The invention relates to the field of materials, in particular to a polyethylene terephthalate composition and a preparation method thereof. Background technique [0002] Dielectric materials, also known as dielectrics, are electrical insulating materials. According to performance, there are high dielectric materials and low dielectric materials. For low dielectric materials, with the rapid development of electronic information technology, electronic products are developing in the direction of lightweight, high performance and multifunctionality, and it is increasingly necessary to develop low dielectric constant ( D. k <3) Materials. At the same time, with the advent of the 5G era, the requirements for the transmission speed and loss of electronic signals are higher than those of 4G products. Usually, 4G products only require the dielectric constant of resin materials to be less than 3.7 (1GHz), while 5G products require The dielectric constant...
