Problems solved by technology

However, in practical applications, it is found that DOPO compounds have a large water absorption rate, poor dielectric properties and poor heat and humidity resistance of the board.
The additive type is mainly phosphazene and phosphonate compounds, and the flame retardant efficiency of the additive type flame retardant is low, and more amount needs to be added to meet the flame retardant requirements
At the same time, because of its low melting point (generally lower than 150°C), it is easy to migrate to the surface of the board during the processing of the laminate, affecting the performance of the board.

Synthetic example 1

[0057] Add 160g (0.5mol) 10-(2,5-dihydroxyphenyl)-10-hydrogen-9-oxa-10- Phosphaphenanthrene-10-oxide (ODOPB) and 360g hydroxyl-containing phenoxy cyclotriphosphazene (wherein the dihydroxy content is greater than 60%) and 816g methyl isobutyl ketone (MIBK), nitrogen replacement under reduced pressure in the system , to dissolve it. Then, 182.7g (0.9mol) of terephthaloyl chloride was put into the reaction for 2 hours, and the temperature in the system was controlled below 60°C; then, 114g (1.2mol) of phenol was added to the system, and the reaction was continued for 1 hour; 189 g of 20% aqueous sodium hydroxide solution are added; stirring is continued for 1 hour under these conditions. After the reaction was completed, the water layer was removed by static liquid separation. Add water into the MIBK phase in which the reactants are dissolved, stir and mix, then separate the liquids at rest, and remove the water layer. The above operations were repeated until the pH of the aq...

Abstract

The invention provides a phosphorus-containing active ester and its halogen-free resin composition, as well as a prepreg and a laminate using the same. The halogen-free resin composition comprises: (A) thermosetting resin; (B) phosphorus-containing active ester resin. Prepregs and laminates made of the halogen-free resin composition have low dielectric loss factor and can realize halogen-free flame retardancy.

Description

technical field [0001] The invention belongs to the technical field of copper-clad laminates, and in particular relates to a phosphorus-containing active ester and a halogen-free resin composition thereof, as well as prepregs, laminates and printed circuit boards using the same. Background technique [0002] With the development of electronic components in the direction of small, light, thin, high performance, and multifunctional, it brings high frequency and high speed signal transmission. This requires that the dielectric constant and dielectric loss of electronic materials are relatively low, which are related to the structure of the material, and low dielectric constant and low dielectric loss resins generally have in structure: large free volume, low polarizability , Low water absorption, low dielectric constant structure and so on. In addition, on July 1, 2006, the EU's two environmental protection directives "Directive on Waste Electrical and Electronic Equipment" an...
