Description
Technical field
The present invention relates to the compositions fields of polyamide, and in particular to a kind of nylon alloy plastic pipe and its preparation work
Skill.
Background technology
Nylon (PA) also known as polyamide, be on molecular backbone containing recurring amide radical group-[NHCO]-thermoplastic resin
Fat general name, including aliphatic PA, aliphatic-aromatic race PA and aromatic series PA.Had using plastic pipe prepared by nylon material excellent
Elegant wearability, heat resistance, mechanical strength, elasticity, toughness and bending fatigue resistance energy.But due to polyamide molecule structure
Feature so that its hydrophily is stronger, has higher vapor sensibility, it must be dried before processing, limits
The application range of nylon pipe, and the shrinkage of nylon material is big, greasy property is poor, and it is relatively low to bear high pressure ability, and
Thermal stability is poor, if not being modified to nylon pipe, so that nylon material due to its stronger hygroscopicity, leads to nylon pipe
The mechanical strengths such as intensity, toughness be gradually reduced, it is impossible to meet industrial needs, service life shortens.Therefore, it is necessary to nylon tube
Material is modified processing, to meet the market demand, expands the application field and occupation rate of market of nylon material.
Plastic alloy is high-performance, functionalization, the customizations for utilizing physical blending or chemical grafting method and obtaining
A kind of new material, it can improve or improve the performance of existing plastics and reduce cost, it has also become the most active in plastics industry
One of kind.
Chinese patent CN200510025568.X discloses a kind of halogen-free flame-retardant nylon 6 and nylon66 fiber alloy, it has mixing
Object forms, and weight proportion composition is：Nylon 630-65, nylon66 fiber 30-65, fire retardant A0.1-15%, fire retardant B0.1-
15%, carbon forming agent 0.1-2%, antioxidant 0.1-1%, anti ultraviolet agent 0.1-1%.But due to nylon 6 and nylon in the patent
66 heat resistance difference is larger, and the viscosity of nylon 6 is larger, it is difficult to carry out extrusion molten, and larger to wear and tear in machines, therefore
Nylon alloy of good performance can not be prepared using the preparation method of the patent.
Chinese patent CN201510124684.0 discloses a kind of nitrile rubber/nylon66 fiber alloy, belongs to mechanical blending height
Molecular material, especially with the high molecular material of nylon66 fiber modified butadiene acrylonitrile rubber.But nitrile rubber and nylon in the patent
Poor compatibility although being added to compatilizer, is still unable to control the homogeneity of alloy material.
Therefore, it is necessary to be modified to nylon material, with improve the water repelling property of nylon pipe, anti-contracility, lubricity,
High pressure ability to bear and thermal stability.
Invention content
The present invention is in view of the above-mentioned problems, provide a kind of nylon alloy plastic pipe and its preparation process, by preparing nylon
Alloy plastic tubing is effectively improved water repelling property, anti-contracility, lubricity, high pressure ability to bear and the thermostabilization of nylon pipe
Performance.
Technical solution is used by the present invention solves the above problems：
A kind of nylon alloy plastic pipe, which is characterized in that prepare the raw material of nylon alloy plastic pipe and its weight hundred
Score is：PA66,30%~45%, PA610,15%~25%, PA1010,15%~25%, PA12,15%~25%, resistance
Fire agent, 0.05%~2%, lubricant, 0.1%~1%, waterproofing agent, 0.5%~2%, antioxidant, 0.05%~1%.
Further, fire retardant is times of antimonous sulfide, magnesium hydroxide, magnesium stearate, ammonium polyphosphate, polyborosiloxane
It is one or more.
Further, lubricant for carbon black, graphite, kaolin, talcum powder, land plaster it is any one or more.
Further, waterproofing agent for aluminium hydroxide, polysiloxanes, calcium chloride, montmorillonite, calcium stearate it is any or more
Kind.
Further, antioxidant is zinc oxide, titanium dioxide, diphenylamines, 2,6- di-t-butyl -1- methoxyl groups are to benzene
Phenol, phosphite ester it is any one or more.
Another goal of the invention of the present invention, is to provide a kind of preparation process of above-mentioned nylon alloy plastic pipe, including
Following steps：
Step A, stock：According to weight percent, precise material resin PA66, PA610, PA1010, PA12, then
Drying and processing is carried out under 50 DEG C~55 DEG C of temperature condition；
Step B, batch mixing：It will be carried out at mixing by material resin PA66, PA610, PA1010, PA12 of drying and processing
Reason, adds fire retardant, lubricant, waterproofing agent, the antioxidant of the weight percent, stirs evenly, obtain mixed melting material；
Step C, extrusion molding：It is cooled to 40 DEG C to mixed melting material to squeeze out from screw extruder hopper, in Screw Extrusion
It is extruded onto outside machine by screw rod into non-individual body after being molded at machine machine head port mould, is closed through cooling, sizing, traction, stretching to get made nylon
Golden plastic pipe.
Further, in step A, drying and processing is：It is dried to moisture content≤0.1% of material resin.
