Description

technical field [0001] The invention belongs to the field of polymer modified materials, and in particular relates to a glass fiber reinforced low-dielectric nylon material and a preparation method thereof. Background technique [0002] With the rapid development of electronic information technology, electronic products are developing in the direction of light weight, high performance and multifunctionality, and it is increasingly necessary to develop low dielectric constant materials with good performance. With the increasing application of polymer materials in electronic products, low dielectric constant polymers have become an important direction of low dielectric material research. [0003] At present, there are few research reports on low dielectric constant polymers. Chinese patent CN105419277A discloses a composite material with low dielectric properties. Based polymerization curing unsaturated polyester resin, vinyl ester resin, one-component polyurethane resin and ...
