Abstract

The present invention discloses a weather-resistant resin composition and applications thereof, wherein the weather-resistant resin composition does not contain a phenolic hydroxyl group so as to solve the problems of easy discoloration and aging caused by the phenolic hydroxyl group contained in the existing weather-resistant resin. According to the present invention, with the application of theweather-resistant resin composition to prepare the copper clad laminate, the performance test results show that the prepared copper clad laminate has excellent heat dissipation, excellent heat resistance, excellent adhesion and insulation reliability, the thermal conductivity is up to 3.03 W/m.K, the peeling strength is 1.58 N/mm, the plate cracking time is more than 30 min, the breakdown voltageafter A-state and D-48/50 water boiling treatment is more than 7.0 kV, the performances such as thermal conductivity, peeling strength, breakdown voltage, thermal stress, Tg, Td and the like after blue light irradiation are not significantly attenuated, and the copper clad laminate has excellent weather resistance, such that the obtained product can meet the weather-resistant requirements of LED plant lighting lamps, and is suitable for the preparation of the prepreg, the laminated plate, the copper clad laminates or the printing circuit boards in 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...
