Paragraph 0054-0055; 0057, (2017/09/08)
The invention relates to the field of fire retardant products, in particular to a fire retardant and a preparation method thereof. The preparation method comprises the following steps: carrying out catalytic reaction on an addition accelerant and 2-hydroxybenzaldehyde in the presence of a catalyst; and then reacting the product with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. By the method, an efficient, halogen-free and environmentally friendly perpetual fire retardant which can be used for preparation of thermosetting resin can be rapidly and conveniently prepared.
