Abstract

The invention provides a preparation method of a biomass charring flame retardant agent, and belongs to the technical field of additives. The method comprises the steps as follows: potato waste residues produced by potato starch production enterprises are dried naturally, smashed, sieved by a 180-300 mesh sieve, soaked in a liquid organic phosphorus flame retardant for 5-10 hours, separated, dried naturally and mixed with expansible graphite, so that the biomass charring flame retardant agent is obtained. The biomass charring flame retardant agent can be widely applied to production of flame retardant products of PP (polypropylene), PE (polyethylene), PS (polystyrene), ABS (acrylonitrile butadiene styrene), PC (polycarbonate), PA (polyamide), EVA (ethylene vinyl acetate), trans-1,4-polyisoprene (TPI), SBR (styrene butadiene rubber), NBR (nitrile butadiene rubber), silicone rubber, polyurethane and the like. An experiment shows: when an additive amount of the biomass charring flame retardant agent ranges from 10% to 30%, all oxygen indexes of the flame retardant materials reach national standards, and the mechanical property is good.

Description

technical field [0001] The invention belongs to the technical field of additives, relates to a composite flame retardant, in particular to a preparation method of a biomass charcoal flame retardant; the invention also relates to the preparation of a flame retardant polymer material by a biomass charcoal flame retardant in the application. Background technique [0002] With the development of flame retardant materials, people pay more and more attention to the development of new flame retardants. The earliest flame retardants used by people are mainly halogen-containing flame retardants. Halogen-containing flame retardants have good flame-retardant effects in polymer materials, and the amount of addition is small, which has little effect on the mechanical properties of materials. Therefore, they play an important role in the field of flame retardants. position has been widely used. However, halogen-containing flame-retardant materials will release a large amount of smoke an...
