The phosphorus-containing epoxy resin composition has the characteristics of halogen-free flame retardance, high humidity and heat resistance, low water absorption, high flame retardance, high peel strength and good dielectric property; the prepreg and the laminated board prepared from the resin composition have the characteristics of halogen-free flame retardance, high humidity resistance, low water absorption, high flame retardance, high peel strength and good dielectric property, and can be used as printed circuit boards for electronic instruments.
Description
Technical Field
The invention relates to a phosphorus-containing epoxy resin composition, and a prepreg and a laminated board prepared from the phosphorus-containing epoxy resin composition, and belongs to the technical field of electronic materials.
Background
In the prior art, the traditional brominated flame retardant such as brominated epoxy resin, tetrabromobisphenol A and the like has excellent flame retardance and relatively low price, and is always the main flame retardant of the common FR-4 copper-clad plate. However, with the improvement of the quality of life and safety awareness of people, the safety requirements of people on electronic products at the sides are higher and higher. Bromine-containing flame retardants generate hydrogen bromide, which is an irritant and corrosive toxic gas such as dioxin and polybrominated dibenzofuran during combustion, and thus harm the health of people and cause pollution. In addition, the bond energy of the carbon-bromine bond in the bromine-containing flame retardant is weaker, so that the thermal decomposition temperature is lower, and the application of the bromine-containing flame retardant in a high-performance copper-clad plate is obviously insufficient.
At present, the development direction of the flame retardant tends to be non-halogenated increasingly, and manufacturers of flame retardant materials in various countries begin to apply the flame retardant to be brominated in high polymers in a strict attitude, and the halogen-free flame retardant, especially the phosphorus flame retardant, gradually becomes the mainstream. Among them, DOPO (9, 10-Dihydro-9-oxa-10-phosphaphenthrene-10-oxide) is the most important, and after the printed circuit board is in high frequency, good flame retardant property and dielectric property can be obtained. However, the DOPO ring has high water absorption rate under high temperature, high humidity or alkaline conditions, which affects the dielectric property and the humidity resistance of the circuit board.
On the other hand, all additive flame retardants in the prior art are physically blended in a resin system and cannot react with the resin, so that the resin system has high water absorption rate and poor heat resistance.
In view of the above problems, it is obvious that the development of a phosphorus-containing epoxy resin composition with halogen-free flame retardance, high moisture and heat resistance, low water absorption, high flame retardance, high peel strength and good dielectric properties, and a prepreg and a laminated board made of the composition have positive practical significance.
