Abstract
The invention belongs to the field of chemical industry, and aims at providing a low-smoke aluminum hypophosphite compounded fire retardant with excellent fire resistance and smoke suppression performance, and a preparation method thereof. The fire retardant is formed by 30-60 parts by weight of aluminum hypophosphite, 20-40 parts by weight of hydrotalcite, 20-40 parts by weight of zinc borate, 5-10 parts by weight of diatomite, 5-10 parts by weight of magnesium oxide and 1-3 parts of coupling agent in a manner of mixing and screening. The coupling agent is a tetrabutyl titanate coupling agent or an aluminate coupling agent. The fire retardant has excellent fire resistance and smoke suppression performance, and after the compounded fire retardant is added, the mechanical property of polymers is not obliviously reduced.
