Problems solved by technology

However, the current existing intumescent flame retardants have uneven distribution of carbon and gas sources, and it is prone to the problem that when the gas source is heated to generate gas, there is not enough carbon source around, so that the porous foam carbon layer cannot be formed efficiently, and the carbon formation efficiency is low. , the high addition amount will affect the flame retardant effect

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.

Description

Technical field: [0001] The invention relates to the technical field of flame retardants, in particular to a linear polymer smoke-suppressing expansion flame retardant and its preparation method and application. Background technique: [0002] Intumescent flame retardant (IFR) is an environmentally friendly green flame retardant, which does not contain halogens and does not use antimony oxide as a synergist, and its system itself has a synergistic effect. When the plastic containing intumescent flame retardant is burned, a carbon foam layer will be formed on the surface, which has the functions of heat insulation, oxygen insulation, smoke suppression, and anti-drip. The generation of corrosive gas is in line with the research and development direction of flame retardants in the future, and has become one of the most active flame retardant research fields at home and abroad. However, the current existing intumescent flame retardants have uneven distribution of carbon and gas ...
