Problems solved by technology

[0003] However, the ordinary epoxy resin used for copper clad laminates contains a large number of benzene rings, which makes the tracking resistance of ordinary FR-4 poor, and the CTI value generally does not exceed 250V
[0004] In addition, adding a large amount of aluminum hydroxide filler can produce a copper clad laminate with a high relative tracking index, and its CTI value is greater than 600V. However, adding a large amount of aluminum hydroxide filler will reduce the processability, heat resistance and alkali resistance of the copper clad laminate. Poor sex

Abstract

The invention provides a halogen-free resin composition and a copper-clad plate prepared by using the composition. The halogen-free resin composition is prepared from the following components in parts by weight: 25-45 parts of phosphorus-containing epoxy resin, 5-10 parts of dicyclopentadiene epoxy resin, 5-20 parts of alicyclic epoxy resin, 40-45 parts of acid anhydride and 3-5 parts of a phosphorus-containing flame retardant. According to the halogen-free resin composition and the copper-clad plate prepared by using the composition disclosed by the invention, the halogen-free resin composition is used for solving problems from the angle of the resin structure; the common epoxy resin and the alicyclic epoxy resin as well as the dicyclopentadiene epoxy resin are matched for use, and cured through the acid anhydride, so that the CTI of the copper-clad plate reaches the requirements greater than 600V. Moreover, aluminum hydroxide filler is not needed to be added into the composition, so that the problem that the processing performance, the heat resistance and the alkali resistance of the copper-clad plate are lowered due to filler addition is avoided.

Description

technical field [0001] The invention relates to the technical field of copper clad laminates, in particular to a halogen-free resin composition and a copper clad laminate prepared using the composition. Background technique [0002] As the insulating base material of printed circuit boards, copper clad laminates are widely used in various electronic and electrical products. As people pay more and more attention to the safety and reliability of electronic and electrical products, higher and higher requirements are put forward for the safety and reliability of copper clad laminates. Among them, tracking resistance is an important reliability index of copper clad laminates. Copper clad laminates with poor tracking resistance are potential hidden dangers caused by fires in electronic and electrical products. Therefore, the copper clad laminate must improve its tracking resistance, that is, have a higher CTI value to ensure its safety and reliability. [0003] However, due to t...
