The present invention is a novel flame-retardant thermosetting resin added with an organic phosphorus compound that can be easily obtained into a high-purity product, especially a highly flame-retardant resin with excellent heat resistance, dimensional stability, electrical properties, etc. The object of the present invention is to provide a thermosetting resin having the following properties. Additive or reactive agents such as organic phosphorus compounds, organic halogen compounds, antimony trioxide, aluminum hydroxide, zinc borate, and the like are conventionally known as flame retardants that impart flame retardancy to thermosetting resins.
In particular, organic phosphorus compound flame retardants are difficult to use for resins containing oxygen atoms in their molecules, such as phenolic resins, epoxy resins, polyurethane foams, polyphenylene oxide resins, and Noryl resins (trade name) manufactured by G and E companies. It has a considerable effect on combustion. However, conventional organic phosphorus compounds such as trischloroethyl phosphate, trisdichloropropyl phosphate, triphenyl phosphate, tricresyl phosphate, cresyl diphenyl phosphate, etc. can achieve flame retardation to a certain extent. However, since these organic compounds are of the additive type, there are drawbacks such as a decrease in the heat resistance and dimensional stability of the thermosetting resin, and the volatilization and oozing of the organic phosphorus compound under high temperature conditions. In order to solve these problems,
There are inventions described in JP-A-101489, JP-A-53-97048, JP-A-53-98355, JP-A-53-104682, JP-A-53-105555, etc., but these inventions mainly relate to polymers of organic phosphorus compounds. It is intended to improve the volatility of the flame retardant under high temperature conditions and also improve other properties by making the organic phosphorus compound a high molecular weight compound. We have not yet reached the point where the drawbacks of molds have been completely eliminated. On the other hand, Japanese Patent Application Laid-open No. 52-29900 describes the use of a reaction product obtained by reacting triglycidyl phosphate and divalent phenols as a flame retardant for epoxy resin. It has been found that it is difficult to manufacture triglycidyl phosphate in high purity products. This also reflects the reference examples of the compounds shown in Table 1 and the oxirane oxygen % (OX-OX
%). Generally, high purity of reactive flame retardants is an essential requirement for stabilizing, uniformizing, and improving the physical properties of plastics using the same. In this respect, the organic phosphorus compound used in the present invention has high purity and satisfies the above requirements. In view of the drawbacks of the conventional flame retardant materials mentioned above, in order to achieve the above object, the present inventors conducted intensive research and found that one or two glycidyl groups in one molecule are easy to produce and have a high yield. By blending an organic phosphorus compound with a reactive flame retardant into a thermosetting resin, a thermosetting resin with excellent heat resistance, dimensional stability, electrical properties, etc., and a high degree of flame retardancy can be produced. The inventors have discovered that the present invention can be obtained, and have completed the present invention. The first invention of the present invention is the general formula ()
