Embodiment 1

[0067] Add 315g bisphenol A type epoxy resin to the round bottom flask equipped with electric stirring, reflux condenser, and thermometer, pass nitrogen protection, turn on the heating device to heat bisphenol A type epoxy resin to 100°C, add 35 g tetraphenol Diethyl ethane and 0.18g triphenylphosphine were dissolved for 10 minutes and started to stir. Start the vacuum pump to evacuate the air in the four-necked round-bottomed flask, keep it below -0.095Mpa for 10 minutes, and then blow nitrogen to break the vacuum. Turn on the heating device to raise the temperature to about 130-140°C, control the exothermic temperature of the reaction at 150-155°C for 120 minutes, add 160g of acetone after the reaction, and dissolve it into a finished product to obtain resin 1. Epoxy equivalent 238g / Eq G Chromaticity 13.9 Hydrolyzed chlorine 238ppm Solid content 69.65%

Embodiment 2

[0069] Repeat embodiment 1, wherein the amount of bisphenol A epoxy resin is 245g, and the amount of tetraphenol ethane is 105g and all the other are the same as embodiment 1.

Embodiment 3

[0071] Repeat embodiment 1, wherein the amount of bisphenol A epoxy resin is 280g, and the amount of tetraphenol ethane is 70g and all the other are the same as embodiment 1.

Abstract

The invention relates to a novel tetrafunctional epoxy resin. The novel tetrafunctional epoxy resin has an ultraviolet light (UV) and fluorescence blocking function, and also has the advantages of short process route, small device investment, low energy consumption, low safety management difficulty and easy environmental protection based on the UV and fluorescence blocking function. The tetrafunctional epoxy resin can be compounded with any one or more epoxy resins to obtain epoxy resin with the UV and fluorescence blocking function, and also can be compounded with a curing agent to obtain a hardener.

Description

technical field [0001] The invention relates to a four-functional epoxy resin, its preparation method, and its application in blocking ultraviolet light and fluorescent properties. Background technique [0002] In today's information age, electronic appliances affect everyone's life, and with the development of the times, electronic appliances are constantly improving. Electronic appliances will inevitably put forward higher requirements for the PCB, which is an important part of it. The circuit density of the PCB has been greatly increased, and the processing technology of the circuit board has been greatly improved. In the past, the traditional process of screen printing thermal solder resistance film was difficult to meet. The increasingly sophisticated circuit requirements are gradually being replaced by the photosensitive solder resist process. The photosensitive solder resist is coated on both sides of the circuit board, and then exposed to ultraviolet light on both si...
