Abstract

The invention discloses an antimony-based compound flame-retardant masterbatch for nylon 66 (PA66) and a preparation method of the antimony-based compound flame-retardant masterbatch. The flame-retardant masterbatch is prepared form, by weight, 40-60 parts of antimony trioxide, 10-30 parts of a flame retardant A, 10-30 parts of a flame retardant B, 2-5 parts of a coupling agent, 2-6 parts of a lubricant and 15-30 parts of PA66 carrier resin. The flame-retardant masterbatch is prepared through the steps of drying, surface modification, high-speed hot mixing, granulation and the like. The antimony-based compound flame-retardant masterbatch for nylon 66 (PA66) has the advantages of being high in flame-retarding efficiency, good in processability and the like, halogen-free and toxicity-free environment-friendly raw materials and auxiliaries are selected for preparation, a good flame-retarding effect can be achieved without adding halogen-based flame retardants for synergism, and the mechanical property of a composite is hardly influenced.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant materials, and in particular relates to an antimony compound flame-retardant master batch for nylon 66 and a preparation method thereof. Background technique [0002] Nylon 66 (PA66) is a polar semi-crystalline polymer. Because it has more amide groups, it can form more hydrogen bonds, so it has strong mechanical properties and a high melting point, so it is widely used as a engineering plastics. Since PA66 contains amino groups, it will release a small amount of inert gas when it is burned and decomposed, so its combustion process is relatively slow and has certain flame retardant properties, but it must be flame retardant modified to achieve V-0 level or oxygen index as high as 30%. However, antimony oxide flame retardant PA66 is usually flame retardant by directly adding antimony oxide powder, the flame retardant effect is poor, and the amount of smoke is large. The mechanical propert...
