Description
Technical field
The present invention relates to the preparation method of a kind of modification of nylon, particularly a kind of polyhexamethylene adipamide composition.
Background technology
Nylon66 fiber (polyamide 66) fiber surpasses nylon 6 in terms of heat resistance and dimensional stability, and in heat resistance
Aspect also surpasses polyethylene terephthalate (polyester) fiber, the most under high humidity conditions heat-resisting
Property and resistance to amine decomposability are all the more so.But, the shortcoming of nylon 66 fiber is, this fiber is in dimensional stability side
Face is inferior to pet fiber.To this end, in the occasion of radial ply tire, it is desirable to have preferably
Dimensional stability, thus mainly use steel wire, pet fiber and staple fibre.Due to
Steel wire and staple fibre are low in terms of the tensile strength of per unit weight, so each tire institute must be improved
The amount of cord, its result is to improve weight and the cost of tire.Polyethylene terephthalate is fine
Dimension is in terms of heat resistance, and heat resistance aspect the most under high humidity conditions is inferior, therefore, poly-to benzene
Naphthalate fiber truck or automobile tire and in terms of the high-speed tire that operating temperature is high should
With being just restricted.In this case, an urgent demand is improved to the dimensional stability of nylon66 fiber, protect again simultaneously
Hold its excellent characteristic, the highest tensile strength, high heat resistance and high fatigue resistance.
It is to divide in nylon matrix with improved polyalkene as the polyolefin of impact modifying agent and the blend of nylon
Dissipating into the phase dispersed structure of island shape (diameter 011～1 μm), its improved polyalkene becomes and absorbs into impact energy
Body, this type of alloy can improve nylon impact strength under low temperature, dry state and reduce hygroscopicity.Nylon with contain
The blend alloy of the composition such as the graft copolymer of the polyolefin of alkyl or its elastomer can get the nylon of ultra-tough
Material.
CN102134392 relates to a kind of flame-retardant PA 66 composite with high glow wire temperature and technique thereof,
It is characterized in that according to mass percent proportioning as follows: PA6673%, brominated polystyrene 20.3%, three oxygen
Change two antimony 4.33%, layered di-hydroxyl composite metal oxidate 2.17%, polytetrafluoroethylene (PTFE) 0.2%；Described multiple
The manufacture craft of condensation material comprises the following steps: PA66 is dried in convection oven at 140 DEG C 4hr, presses
Component formula mixes；By granulation, the composite wood that simultaneously will obtain are blended in double screw extruder
Material injection mo(u)lding in injection machine；The invention has the advantages that: product glowing filament ignition temperature >=750 DEG C, fire-retardant
Property 94UL-V0 level (0.8mm, 1.6mm), maintain the excellent mechanical performances of conventional bromine system flame-retardant PA 66 material,
Meet the requirement of the electronic element device materials in white domestic appliances field.
EP649738 discloses by adding polyglutarimide to polyamide, can produce a kind of power of enforcement
Locking polyamide and the connection of polyvinyl fluoride.So, such as, by using the step extrusion process can be by gathering
Acid amides and polyvinyl fluoride prepare the laminate (Iaminate) of pair of lamina and by polyamide, by the poly-glutaryl of polyamide
The adhesive promoter layer of the mixture composition of imines, and polyvinyl fluoride prepares the laminate of three layers.
The existing composition known technology containing PA66 all has complicated components, poor compatibility between high molecular polymer,
Mix the shortcomings such as uneven, have impact on the using effect in commercial plant.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of polyhexamethylene adipamide composition.
By polyhexamethylene adipamide (nylon66 fiber), polytrifluorochloroethylene, Kynoar, polytetrafluoroethylene (PTFE)
POE-g-MAH toughener, is blended in certain proportion, after mixture is melted by melt pelletization method routinely,
It is depressed into granulator granulation with nitrogen, is dried after cooling, obtains product.
Present invention multiple polymers in hybrid resin the most at high temperature has the trend of polymerization further, can improve
Nylon66 fiber and the compatibility of PTFE polymer.
The present invention provides a kind of polyhexamethylene adipamide composition, is realized by following steps:
By 100 parts of polyhexamethylene adipamide (nylon66 fiber), 0.5-2 part polytrifluorochloroethylene, 0.5-2 part is poly-partially
PVF, 10-30 part polytetrafluoroethylene (PTFE), 1-5 part POE-g-MAH toughener, in certain proportion at a high speed
It is blended in mixer, by the common melt-processing methods granulation of thermoplastic polymer well known in the art, after cooling
It is dried, obtains product.
The composition of the present invention is added by the common melt-processing methods of described thermoplastic polymer well known in the art
Work becomes useful material, pure or compounding, single and multi-component shape and goods.These methods
Representative instance is granulation, granulation, melt compounded, melt blending, injection, die casting, melt ejection, melt
Compression moulding, melt extrude, founding etc..
Described polytrifluorochloroethylene, Kynoar, polytetrafluoroethylene (PTFE), it is commercially available prod.Such as Ju Hua group
The product that company develops.
Described POE-g-MAH toughener is commercially available prod.The product produced such as Cambridge, Shanghai plastics Co., Ltd.
Described high-speed mixer is commercially available prod, the high-speed mixer product produced to mechanical major such as Nanjing wheat.
Described nylon66 fiber is commercially available prod, such as Baiyun District, Guangzhou City Yi Long plastic material factory product.
Beneficial effects of the present invention:
Nylon66 fiber, through polytrifluorochloroethylene, Kynoar, POE-g-MAH blending and modifying, improves with poly-
The compatibility of tetrafluoroethene, sufficiently can contact during being pulverized and mixed, scattered evenly.Fluorine-containing
Polymer is coated with at nylon66 fiber particle surface, reduces the surface energy of nylon66 fiber particle, improves particle table
The scratch resistance in face, makes the coefficient of friction of composition be reduced.
