Abstract

A phosphorus-containing organic silicone was synthesized from -glycidoxypropyltrimethoxysilane and phosphoric acid reacting.Phosphorus-containing organic silicone/epoxy hybrid resins were prepared by sol-gel method

and the cured resins were prepared from the in situ curing of the bisphenol-A type epoxy resin/4

4'-diaminodiphenylmethane

and phosphorus-containing organic silicone.The properties of the hybrid resin and neat epoxy resin were studied by using thermogravimetric analysis

differential scanning calorimetry

limited oxygen index

tensile strength and impact strength measurements.The flame retardancy was indicated by the limited oxygen index in the range of 25.8~29.3

higher than that of the neat epoxy resin.The glass transition temperature is in the range of 161~179℃

higher than that of the neat epoxy by resin.The thermal stability of the hybrid resin is not superior to that of the neat epoxy resin at low temperature

however

the char yield of it can reach 26.5%

higher than that of the neat epoxy by 36% at 800℃.The tensile strengths of the hybrid resin are 60~80 MPa

higher than that of the neat epoxy resin and the impact strengths can reach 14.36 kJ/m2

higher than that of the neat epoxy resin by 14%.Compared to the neat epoxy resin

the hybrid resin possesses better flame retardancy and thermal stability

and the tensile strength and impact strength are improved.
