The halogen-free flame-retardant nylon resin composition provided by the invention fully adopts a halogen-free flame retardant as a flame retardant material, but the overall performance achieves the performance index of a nylon resin composition using a halogen flame retardant.
Description
Technical field
The present invention relates to polymeric material field, relate in particular to a kind of halogen-free flame-retardant nylon resin composition.
Background technology
Nylon resin, it is polymeric amide, have excellent mechanical strength, wear resistance, self lubricity, erosion resistance and machine-shaping property preferably, at present oneself become output maximum in the five big general engineering plastic, kind at most, the base resin of the widest, the high comprehensive performance of purposes.The flame retardant type nylon resin composition of prior art is that ZL201110117041.5 is disclosed, and it is as follows that the disclosed flame retardant type nylon resin of ZL201110117041.5 composition is counted the component that comprises by weight:
Its preferred version of the disclosed flame retardant type nylon resin of ZL201110117041.5 composition comprises that also parts by weight are 7～15 parts fire retarding synergist.
In the disclosed flame retardant type nylon resin of ZL201110117041.5 composition, described compatilizer is selected from least a in glycidyl acrylate, maleic anhydride graft polyolefine and vinylbenzene one copolymer-maleic anhydride.
In the disclosed flame retardant type nylon resin of ZL201110117041.5 composition, described glass fibre is alkali free glass fibre.
In the disclosed flame retardant type nylon resin of ZL201110117041.5 composition, described fire retardant is selected from least a in TDE, three-(tribromophenoxy)-triazine, brominated Polystyrene, brominated epoxy resin and the trimeric cyanamide urate; Fire retarding synergist is selected from least a in oxide compound, stibnate and the V family metallic element compound of antimony.
In the disclosed flame retardant type nylon resin of ZL201110117041.5 composition, described anti-dripping agent is selected from ptfe micropowder, polytetrafluoroethylene granule and is at least a in the tetrafluoroethylene master batch of carrier with acrylonitritrile-styrene resin, acrylonitrile-styrene-butadienecopolymer or polystyrene resin.
In the disclosed flame retardant type nylon resin of ZL201110117041.5 composition, described oxidation inhibitor is selected from 4,4'-thiobis (the 6-tertiary butyl-3-methylphenol), tris phosphite (2, the 4-di-tert-butyl-phenyl) and four [β-(3,5 di-tert-butyl-hydroxy phenyls) propionic acid] at least a in the pentaerythritol ester, described lubricant is selected from least a in ethylene bis stearamide, tetramethylolmethane stearate and the polyethylene wax.
The disclosed this flame retardant type nylon resin composition of ZL201110117041.5 can use any known plastic working method preparation, as by processing such as forcing machine, mixing machine, kneaders, can be periodical operation, also can be operate continuously.The method that provides among the embodiment is to use the preparation of twin screw extruder melt-blending process, and each component mixes back employing standard twin screw extruder and standard technology extruding pelletization, namely gets a kind of flame retardant type nylon resin composition.
The disclosed this flame retardant type nylon resin composition of ZL201110117041.5 by adding the fire retardant modification, makes the flame retardant properties excellence of whole resin combination; Simultaneously, the consistency of each component is better in the prescription, the synergy of lubricant and oxidation inhibitor, can improve the processing flowability of nylon resin, improve the dispersing property of fire retardant in composition, prepared flame retardant type nylon resin composition outdoor weatherability can be good, shock strength, bending strength and tensile strength height, fire-retardant degree well, mobile high.But from its prescription, be not difficult to find out, its fire-retardant employing be halogen containing flame-retardant, simultaneously be used as fire retarding synergist for the flame retardant effect that promotes halogen containing flame-retardant has also cooperated oxide compound, stibnate or the V family metallic element compound of antimony.Halogen containing flame-retardant refers to contain the fire retardant of elements such as Cl, Br, F, halogen containing flame-retardant is the maximum flame retardant products of fire-retardant application in the present plastic, rubber material, mainly be that it is organic fire-retardant, chemical property is inertia, relatively good with the consistency of plastics, good flame retardation effect, use cost are low, and many features all are that other fire retardant is irreplaceable, but the Halogen fire retardant material can produce a large amount of smog and poisonous corrosive hydrogen halides gas, causes secondary harm.Now forbid fully in some developed countries, obviously prior art has further improved necessity.
Summary of the invention
The object of the present invention is to provide a kind of halogen-free flame-retardant nylon resin composition, to overcome the problem that prior art exists.
A kind of halogen-free flame-retardant nylon resin composition of the present invention, count by weight that it is composed as follows:
