Abstract

The invention relates to a silanol containing phosphazene compound, a flame retardant, an epoxy resin composition and a composite metallic substrate. The phosphazene compound has a molecular structure represented by a formula I shown in the description, wherein M is one or a combination of at least two of a cyclotriphosphazene group, a cyclophosphazene group with four or more cycles and a non-cyclic polyphosphazene group; R is any reactive capping group meeting chemical environments; R1 and R2 each independently is any reactive or non-reactive capping group meeting chemical environments; Y is any non-reactive capping group meeting chemical environments; and a is an integer greater than or equal to 0, b is an integer greater than or equal to 1, and the sum of the a and the b is double the number of phosphorus atoms on the M group. Thus, the phosphazene compound has good flame retardance, and condensates of the phosphazene compound have good heat resistance, water resistance, cohesiveness, mechanical properties and electric properties. In addition, the composition is applied to the composite metallic substrate and circuit boards, and the flame retardance and dielectricity of the composite metallic substrate and the circuit boards can be improved.

Description

technical field [0001] The invention belongs to the technical field of flame retardant substances, and in particular relates to a phosphazene compound with silanol, a flame retardant, an epoxy resin composition and a composite metal substrate. Background technique [0002] Electronic products such as mobile phones, computers, cameras, and video game consoles, household and office electrical products such as air conditioners, refrigerators, TV images, audio products, and various products used in other fields, all need to have different degrees of flame retardancy for safety. [0003] The traditional technology generally adopts adding inorganic flame retardant substances such as aluminum hydroxide hydrate, magnesium hydroxide hydrate and other metal hydroxides containing crystal water to the material system, and adding brominated bisphenol A, brominated bisphenol A, brominated The method of organic flame retardant substances with relatively high halogen content such as bisphen...
