Problems solved by technology

[0007] These copper clad laminates made of DOPO epoxy resin have good flame retardant properties, but there are many defects in adhesion, heat resistance, processability, etc., and are not suitable for manufacturing high-layer, high-strength laminates required by modern communications. Products with reliability, high adhesion, and good processing performance, and due to high cost, are not conducive to popularization in consumer electronics and other consumer electronics that require low cost, such as mobile phones.

The phosphazene compound has a molecular structure represented by a formula I shown in the description, wherein R1, R2 and R3 each independently is any organic group meeting chemical environments; R4 is -OH or any organic group meeting chemical environments; R5 and R6 each independently is any organic group meeting chemical environments; R is any organic group meeting chemical environments; X is any of -O-, -S- and -NH-; Y is any inert nucleophilic group meeting chemical environments; a and b each is an integer greater than 0, and the sum of the a and the b is double the number of phosphorus atoms on the M group; c, d and f each is 0 or 1, and d is not equal to 0 when c is not equal to 0; e is an integer greater than 0; and 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. Copper clad laminates prepared from the phosphonate radical containing phosphazene compound have low dielectricity and good flame retardance.

Description

technical field [0001] The invention relates to the technical field of flame retardant substances, in particular to a phosphazene compound containing a phosphonate group, a molding compound and a composite metal substrate. Background technique [0002] Electronic products represented by mobile phones, computers, cameras, and electronic game consoles, household and office electrical products represented by air conditioners, refrigerators, TV images, audio products, etc., and various products used in other fields, for the sake of safety, a large part All products are required to have different degrees of flame retardancy. [0003] In order to make the product meet the required flame retardant properties or grades, traditional technologies often use inorganic flame retardants such as aluminum hydroxide hydrate, magnesium hydroxide hydrate and other metal hydroxides containing crystal water to the material system. Substances, and adding to the system materials such as brominate...
