Abstract

The invention discloses an expansion-type halogen-free flame retardant and a flame retardant master batch using same. The expansion-type halogen-free flame retardant comprises the following components by weight percent: 25-35% of phosphide, 15-25% of diaminodiphenyl methane and 45-55% of amines expanding agent. The flame retardant master batch comprises the following components by weight percent:50-65% of expansion-type halogen-free flame retardant, 2-3% of polyethylene wax, 30-45% of carrier resin and 1-2% of auxiliary agent. The invention has the advantages that due to a nitrogen-phosphorus compound, volatile acid can be generated at the early period of heating, and the acid has a dehydration function and can carbonize fabrics; and a viscous carbonization product expands under the action of an inert gas released by a gas source, water vapor generated from reaction and micromolecular volatile matters generated by polymer degradation, therefore, a carbon layer with a microporous structure can be formed. The microporous carbon layer has the functions of isolating heat and oxygen and causing a flame to be automatically extinguished, does not lead to liquid drips, and reduces the pollution to the environment.

Description

technical field [0001] The invention relates to an intumescent non-halogen flame retardant and a flame retardant masterbatch using the flame retardant. Background technique [0002] The existing polypropylene non-woven fabrics are all made of polypropylene and polyethylene blended and extruded to granulate, and the biggest disadvantage of this kind of material is that it is easy to burn, has high calorific value, fast burning speed, and there is burning drop phenomenon. It is easy to cause fire, and there are unsafe factors in the application of industrial textiles. Contents of the invention [0003] The purpose of the present invention is to provide an intumescent halogen-free flame retardant and a flame retardant masterbatch using the flame retardant, which can effectively solve the problems of the existing non-woven fabrics that are easy to burn, have high calorific value, and are easy to cause fire. [0004] In order to solve the above technical problems, the present ...
