Abstract

The organic-inorganic composite flame retardant relates to a composite flame retardant with smoke suppression and flame retardant properties, good compatibility with organic materials, and reinforcing effect on organic materials. Its chemical composition is: [M 2+ 1-x m 3+ x (OH) 2 ] x+ A n- x / n ・yH 2 O where: M 2+ is Mg 2+ , Ca 2+ , Mn 2+ , Fe 2+ ,Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ One of the divalent metal cations; M 3+ is al 3+ , Fe 3+ , Cr 3+ ,Co 3+ One of the trivalent metal cations; A n- It is an inorganic or organic mixed anion with flame retardancy or assisting flame retardancy with an average valence of n. The value range of n is 1≤n≤6; the value range of x is 0.1<x<0.5; the value of y is The value is related to the preparation conditions, and the value range is 0≤3y≤5; it has a layered structure, which is determined by M 2+ and M 3+ The hydroxide layer and the interlayer anion A n- constitute.

Description

technical field [0001] The invention relates to a kind of flame retardant compounded with organic flame retardants and inorganic flame retardants by chemical methods, especially having smoke suppression and flame retardant properties, good compatibility with organic materials, and reinforcing effect on organic materials composite flame retardants. Background technique [0002] In recent years, the widespread use of synthetic polymer materials has brought us various conveniences and comforts. But because most of them are combustible substances, if the problem of flame retardancy is not considered, the hidden danger of fire will inevitably plague us all the time. For example, many residential fires are said to originate from packaging materials for heat-generating appliances, such as television casings, that have not been flame-retardant treated. For this reason, it is necessary to develop flame retardant technology to make polymer materials into flame retardant materials. ...
