Abstract

The invention discloses a high-transparency low-dielectric-loss toughened cyclic polyolefin material and a preparation method thereof. The toughened cyclic polyolefin material comprises the followingcomponents in parts by weight: 70-85 parts of COC resin, 10-20 parts of an elastomer and 5-10 parts of a compatilizer, wherein the elastomer is at least one of a styrene-butadiene-styrene block copolymer and a styrene-ethylene-butadiene-styrene block copolymer. The cyclic polyolefin material is high in impact, the notch impact property is greater than 13KJ / m < 2 >, and the basic impact requirements and light transmission requirements of the communication industry, the electronic industry and the household appliance industry can be met. Meanwhile, the invention also discloses a preparation method of the cyclic polyolefin material.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a highly transparent and low dielectric loss toughened cyclic polyolefin material and a preparation method thereof. Background technique [0002] Although the existing cyclic polyolefin materials have low dielectric constant and loss, they have low impact strength and cannot meet the requirements for comprehensive performance of materials. Although the existing technology can improve the impact strength, the transparency is lost at the same time, and the dielectric loss and dielectric constant are also increased. Contents of the invention [0003] Based on this, the object of the present invention is to provide a high transparency and low dielectric loss toughened cyclic polyolefin material by overcoming the disadvantages of the above-mentioned prior art. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a h...
