Abstract
The invention provides a linear polymer smoke suppression intumescent flame retardant, a preparation method thereof and an application of the flame retardant. The linear polymer smoke suppression intumescent flame retardant comprises a first component, a second component and a third component, wherein the first component comprises, by weight, 80-120 parts of acrylic polymers containing epoxy sidegroups, 60-80 parts of dicyandiamide, 2-10 parts of catalysts, 40-60 parts of water, 20-40 parts of alcohol solvents and 20-40 parts of benzene solvents, the second component comprises ammonium polyphosphate, and the third component comprises ammonium molybdate. According to the flame retardant, the side-chain epoxy polymers react with the dicyandiamide, carbon sources and air sources are uniformly and adjacently distributed, and the flame retardant avoids the problem that porous foam carbon layers cannot be efficiently formed as no sufficient carbon sources are available around when the air sources are heated to generate gas, the flame retardant using the formula is high in carbonizing efficiency, good in flame-retarding effect, low in cost, easy to popularize and considerable in market prospect, and needed additive amount is small.
