A kind of modified cyclic polyolefin material and its application

Abstract

The invention discloses a modified cyclic polyolefin material, which is characterized in that it comprises the following components: 100 parts of cyclic polyolefin resin; 1-30 parts of reinforcing fiber whose dielectric constant is less than or equal to 8. The modified cyclic polyolefin material of the present invention not only improves the heat distortion temperature and dimensional stability of the cyclic polyolefin resin by adding a certain amount of reinforcing fibers with a dielectric constant less than or equal to 8 in the cyclic polyolefin resin, It also maintains a low dielectric constant and dielectric loss to meet the high-frequency requirements of modern communications.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified cyclic polyolefin material and its application. Background technique [0002] The cyclic polyolefin material, one of the existing low dielectric materials, has a relatively low thermal deformation temperature and a relatively large linear expansion coefficient, although the dielectric constant and loss are low, which cannot meet the requirements of the modern high-frequency communication field. The material requires high heat resistance and high dimensional stability. [0003] CN201210410056.5 discloses a resin composition, the main components of which are polyphenylene ether resin, cyclic olefin copolymer, 1,2,4-trivinylcyclohexane resin and / or 1,3,5-triethoxy Methylcyclohexane resin, and cyanate resin containing polyphenylene ether structure. It has the effects of low dielectric constant, low dielectric loss, high heat resistance and high glass transition...
