The invention discloses a preparation method of an efficient
polypropylene flame-retardant synergistic master batch, and relates to the technical field of
high polymer materials, and the preparation method is as follows:
glyceryl stearate and
polyolefin are uniformly mixed to form a mixture, and the mixture is extruded by a twin-screw extruder to prepare the efficient
polypropylene flame-retardant synergistic master batch; the
polyolefin is any one or more of
polypropylene of 1100N, polypropylene of K7227H or polypropylene of RE420MO; the
glyceryl stearate is any one or more of tripolyglyceryl monostearate, decapolyglyceryl
stearate, diisostearin, tripolyglyceryl distearate and hexapolyglyceryl pentastearate; the polyglyceryl
stearate is any one or more of tripolyglyceryl monostearate, decapolyglyceryl
stearate, diisostearin, tripolyglyceryl distearate and hexapolyglyceryl pentastearate; according to the invention, polypropylene is used as matrix resin,
glyceryl stearate is used as an additive for blending
extrusion to prepare the
flame-retardant synergistic master batch, and the aim of improving the performance of the
halogen-free flame-retardant polypropylene material is fulfilled by using the characteristics of self-
lubrication, dispersion assistance and flame retardance assistance of glyceryl stearate.
