Description
Technical field
The present invention relates to a kind of polymer composite, especially relate to a kind of antimicrobial halogen-free flame PET/PA6 alloy material
Material and preparation method thereof.
Background technology
Polycaprolactam (PA6) has mechanical strength height, softening point height, impact flexibility advantage good, heat-resisting, solvent-proof,
But price comparison is high.Polyethylene terephthalate (PET) is kind important in thermoplastic polyester, resistance to creep and fatigue
Performance is good, and case hardness is high, and price is low.PET with PA6 makes alloy material can make system possess good thermostability, resistance to
Solvent borne and mechanical performance, it is possible to reduce cost.
At present, improving one of plastic material fire resistance most efficient method is to add bromo-antimony compound system fire retardant.Should
System good flame retardation effect, addition are low, little to the Effect on Mechanical Properties of material, but owing to discharging generation hydrogen bromide when it burns
Deng harmful substance, health and environment to people all can cause and greatly endanger, and affects the electrical property of material very big, therefore its
Range of application is increasingly restricted.Parliament of European Union and EU Council " are closed by No. 2002/95/EC on January 23rd, 2003
In at the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment ", limit some brominated flame-retardant at electronic and electrical equipment
In application, therefore high fire-retardance, high safety, low toxicity, low cigarette, non-corrosiveness gas produce halogen-free type fire proofing oneself become near
The trend of fire proofing research and development over Nian.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of good flame retardation effect,
CTI value is high, can be widely used for the antimicrobial halogen-free flame PET/PA6 alloy in the fields such as electric, information, automobile and office equipment
Material and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of antimicrobial halogen-free flame PET/PA6 alloy material, this alloy material is made up of the component comprising following weight portion:
PET 10-30,
PA6 40-70,
Antioxidant 0.1-0.6,
Lubricant 0.1-1,
Bulking agent 0.01-0.1,
Phosphorus flame retardant 5-8,
Nitrogenated flame retardant 1-8,
Antibacterial 0.2-3
Mineral powder 10-30.
The viscosity of described polyethylene terephthalate (PET) is 0.7-1.3dL/g；Described polycaprolactam
(PA6) viscosity is 2.4-2.8dL/g；
Described antioxidant is tetramethylolmethane hard ester antioxidant and double (3, the 5-di-t-butyl-4-hydroxyls of N, N '-hexa-methylene
Hydrocinnamamide) antioxidant compounding forms by weight 1: 1.
One or more in tetramethylolmethane stearate, white beeswax oil, lignite wax of described lubricant；
Described bulking agent is selected from double (2-oxazoline), ethylene-methyl methacrylate sodium ionomer or ethylene-methyl methacrylate
One or more in zinc ionomer；
Described phosphorus flame retardant is selected from triphenyl phosphate, tricresyl phosphate, cresyl diphenyl phosphate and polycondensation
The mixture of one or more of aryl phosphate ester；
Described nitrogenated flame retardant is selected from melamine cyanurate, melamine polyphosphate, melamine pyrophosphoric
The mixture of one or more in salt and APP；
Described antibacterial is for carrying silver zinc zeolite, and the weight content of silver is 4～8%, and the weight content of zinc is 4～8%.
Described mineral powder is the mica powder through coupling agent surface treatment or Pulvis Talci, particle diameter 600 mesh to 2000 mesh it
Between, described coupling agent is titanate coupling agent or silane coupler.
A kind of preparation method of antimicrobial halogen-free flame PET/PA6 alloy material, the method comprises the following steps:
(1) get the raw materials ready according to following components and weight portion content:
PET 10-30,
PA6 40-70,
Antioxidant 0.1-0.6,
Lubricant 0.1-1,
Bulking agent 0.01-0.1,
Phosphorus flame retardant 5-8,
Nitrogenated flame retardant 1-8,
Antibacterial 0.2-3
Mineral powder 10-30；
(2) by polyethylene terephtalate and PTT PA6 drum at 120 DEG C
Air-dry dry 3 hours；
(3) by dried PET and PA6 together with the lubricant got ready, antioxidant, bulking agent and fire retardant, antibacterial, ore deposit
Thing powder mix homogeneously in high-speed mixer；
(4) material of mix homogeneously is carried out in double screw extruder extruding pelletization, through water-cooled, pelletizing, be dried i.e.
Obtain product.
The temperature of the double screw extruder described in step (4) is 200-270 DEG C.
Fire retardant easily generates carbon-coating, the generation of accelerated material creepage trace under DC Electric Field.Cut off surface carbon
The connection of grain is to improve material resistance to electricity one effective method of trace.The addition of mineral powder can play dilution fire retardant, dispersion
Uniform effect, can effectively intercept the formation of carbon-coating under high electric field action, and can improve Flame Retardancy energy.Muscovitum
Powder, Pulvis Talci two-dimension plane structure also have potentiation to material.Add load silver zinc zeolite energy slow release go out silver ion, zinc from
Son, can destroy cell membrane or the activity of cellular plasm organized enzyme of antibacterial under very low concentrations, thus kill antibacterial.
Compared with prior art, the invention have the advantages that
1, add mineral powder and can play dilution fire retardant, finely dispersed effect, can be effective under high electric field action
Intercept the formation of carbon-coating, and Flame Retardancy energy can be improved；
2, add mica powder, Pulvis Talci two-dimension plane structure also has potentiation to the mechanical performance of material；
3, method is reasonable, technique is simple, non-corrosiveness gas produces, safety and environmental protection.
4, good flame retardation effect, CTI value height, can be widely used for the fields such as electric, information, automobile and office equipment.
5, the load silver zinc zeolite added can effectively kill the antibacterial of material surface.
