Embodiment 1-1

[0072] At 165±5°C, 91.5 grams of TPE (Borden Chemical, U.S.A., the following TPE products were purchased from The manufacturer) and 885 grams of TBBA (DEAD SEA, Israel, the following TBBA products are all purchased from the manufacturer) with 1875 grams of general-purpose bisphenol A epoxy resin (epoxy equivalent weight (E.E.W.): 186 grams / equivalent, YD-128, Kukdo Chemical Co. Ltd., Korea) was subjected to bulk polymerization for 3 hours to prepare a modified epoxy resin composition (E.E.W.: 482 g / equivalent) containing the compound shown in formula (7). The composition thus obtained exhibited high flame retardancy and UV barrier properties, a TPE modification rate of 3.20% by weight, and a bromine content of 18.00% by weight.

Embodiment 1-2

[0074] At 165±5°C, using ETPPI as a catalyst, 75.6 g of TPE and 720 g of TBBA were mixed with 1500 g of general-purpose bisphenol A epoxy resin (E.E.W.: 186 g / equivalent, YD-128, Kukdo Chemical Co.Ltd ., Korea) carried out bulk polymerization for 3 hours to prepare a modified epoxy resin composition (E.E.W.: 501 grams / equivalent) containing the compound shown in formula (7). The composition thus obtained exhibited high flame retardancy and UV barrier properties, a TPE modification rate of 3.29% by weight, and a bromine content of 18.19% by weight.

Embodiment 1-3

[0076] At 165±5°C, using ETPPI as a catalyst, 56.92 g of TPE and 720 g of TBBA were mixed with 1500 g of general-purpose bisphenol A epoxy resin (E.E.W.: 186 g / equivalent, YD-128, Kukdo Chemical Co.Ltd ., Korea) carried out bulk polymerization for 3 hours to prepare a modified epoxy resin composition (E.E.W.: 480 grams / equivalent) containing the compound shown in formula (7). The composition thus obtained exhibited high flame retardancy and UV barrier properties, a TPE modification rate of 2.50% by weight, and a bromine content of 18.34% by weight.

Abstract

Disclosed is a with a modified epoxy resin compound with flame-retardant and UV-blocking functions. Because the epoxy resin compound not only has a high degree of flame-retardant and UV-blocking functions, but also has electricity and thermal properties, it can be used to produce printed circuit boards (PCBs).

Description

technical field [0001] The present invention relates to a kind of modified epoxy resin with high flame retardancy and ultraviolet barrier property, more specifically relates to a kind of modified epoxy resin, wherein the epoxy resin uses 2,2',6,6 containing bromine atom '-Tetrabromobisphenol A (hereinafter referred to as "TBBA") and tetraphenylethane (hereinafter referred to as "TPE") with UV blocking effect for modification. Background technique [0002] Flame retardant plastics are recently in demand in different industrial fields including the electronics industry. It is well known that most flame retardant materials are compounds containing halogens, phosphorus or nitrogen as well as inorganic compounds. In addition, it has been found that halogenated aliphatic, aromatic and cycloaliphatic compounds substituted with bromine or chlorine exhibit a high degree of flame retardancy. Melamine and its derivatives and inorganic compounds such as aluminum hydroxide and magnesiu...
