Abstract
The invention discloses a precipitate-free flame retardant masterbatch, which comprises the following compositions in part by weight: 5 to 10 parts of modified polyamide, 5 to 30 parts of flame retardant, 0 to 30 parts of flame retardant synergist and inorganic packing, and 0.5 to 5 parts of dispersing agent, wherein the weight ratio of the flame retardant to the flame retardant synergist is 10-25:100. Flame retardant materials prepared by adding the precipitate-free flame retardant masterbatch into high polymer materials do not have the precipitated flame retardant even if used for a long time, and have good flame retardant effect. Because flame retardant is not precipitated, the surfaces of the flame retardant materials have no 'frosting' phenomenon, and the flame retardant materials prepared from the flame retardant masterbatch are excellent in appearance.
Description
Technical field
The present invention relates to a kind of flame-retardant master batch, particularly a kind of precipitate-free flame retardant masterbatch.
Background technology
Bromine is that organic fire-retardant is one of best organic fire-retardant of flame retardant resistance, but some bromide fire retardants are in process of production, can produce toxic and harmful, both contaminate environment, more influence workers'health.
Have certain safety problem although bromine is an organic fire-retardant, because its flame retardant properties is superior, price is comparatively cheap, is still used in a large number in fire retardant material.
A lot of bromide fire retardants are as decabromodiphenyl oxide, eight bromo ether etc., with the mixed fire retardant material that gets of polymer, after long-time the use, this based flame retardant can be separated out in surface at fire retardant material, and this can cause the flame retardant properties of fire retardant material to descend, and influences the work-ing life of material.Meanwhile, the fire retardant of separating out can be present in material surface with the form of " bloom ", influences the outward appearance of product.
People wish the flame-retardant master batch that has a kind of nothing to separate out.
Summary of the invention
The object of the present invention is to provide a kind of precipitate-free flame retardant masterbatch.
The technical solution used in the present invention is:
A kind of precipitate-free flame retardant masterbatch, be made up of modified polyamide 5～10 weight parts, fire retardant 5～30 weight parts, fire retarding synergist, mineral filler 0～30 weight part, dispersion agent 0.5～5 weight part, wherein the amount ratio between fire retardant and the fire retarding synergist is 10～25: 100.
Modified polyamide comprises the elastomer-modified polymeric amide of vinyl of polypropylene grafted maleic anhydride modified polyamide, ethylene-octene copolymer grafted maleic anhydride modified polyamide, maleic anhydride, acrylate bifunctionalization.
Preferably, fire retardant adopts bromide fire retardant.
Precipitate-free flame retardant masterbatch of the present invention is added into the fire retardant material that makes in the macromolecular material, and life-time service does not have fire retardant yet separates out, the fire retardant material good flame retardation effect that makes.
Because no fire retardant is separated out, and does not also have " frosting " phenomenon on the surface of fire retardant material, by the fire retardant material that flame-retardant master batch of the present invention is made, excellent in appearance.
