Abstract

The application discloses a weather-resistant resin composition and its application. The weather-resistant resin composition does not contain phenolic hydroxyl groups, which solves the problem of easy discoloration and aging of the existing weather-resistant resins due to the phenolic hydroxyl groups. The weather-resistant resin composition of the present application is used to prepare copper-clad laminates. Through performance tests, it can be known that it has excellent heat dissipation, heat resistance, adhesion and insulation reliability, and its thermal conductivity is up to 3.03W / m·K. The peel strength is 1.58N / mm, the frying plate>30min, the breakdown voltage after A state and D‑48 / 50 boiling treatment is>7.0kV, and the thermal conductivity, peel strength, breakdown voltage, thermal stress, Tg, Td and other properties have no obvious attenuation, and have excellent weather resistance. Therefore, it meets the weather resistance requirements for preparing LED plant lighting substrates, and is suitable for preparing prepregs, laminates, copper-clad laminates or printed circuit boards for LED plant lighting.

Description

technical field [0001] The present application relates to the technical field of copper clad laminates, in particular to a weather-resistant resin composition and its application. Background technique [0002] In recent years, LEDs have gradually entered the lives of ordinary people, and LEDs can be seen in various fields of general lighting. LED has advantages that cannot be replaced by traditional lighting, and it also has more room for development. The evolution of the lighting market to the direction based on semiconductor technology has given rise to many new growth opportunities, one of which is plant lighting. LED plant lighting has many advantages, such as increasing the growth rate of crops, saving energy up to 75% and saving water resources up to 90%, etc., which has promoted the development of the plant and horticultural lighting market. [0003] Different from ordinary LED lighting, in order to meet the needs of plants for photosynthesis, the outgoing light wave...
