Abstract
The invention discloses a special polypropylene plastic used for capacitor shells. The special polypropylene plastic comprises, by weight, 100 parts of polypropylene, 20-30 parts of talcum powder, 10-20 parts of fiberglass, 30-50 parts of 1,2-bis(pentabromophenyl) ethane, 0.1-0.3 parts of antioxidant 1010, 0.1-0.3 parts of lubricant, and 0.2-0.4 parts of surfactant HK-550. As a novel thermoplastic reinforced composite material, the special polypropylene plastic provided by the invention has advantages of high elastic modulus, high strength, high heat deflection temperature, good dimensional stability, good flame retardant property, and the like. The special polypropylene plastic provided by the invention is mainly used for producing capacitor shells.
Description
Technical field
The present invention relates to a kind of plastics, relate in particular to the polypropylene dedicated plastics of a kind of capacitor protector.
Background technology
Polypropylene, english abbreviation is PP, is nineteen fifty-seven at first to drop into industrial production in Italy, is another the important plastics variety after polyethylene (PE).It has preferably thermotolerance, can be not destroyed at 135 ℃ of boiling 1000h yet, and the specific heat capacity of PP, thermal conductivity are all less than PE, but heat insulating ability is better than PE.PP belongs to non-polar polymer, has excellent dielectricity and electrical insulating property, and electrical property is not subjected to the impact of ambient moisture and electric field frequency substantially, and in the working range that allows, the temperature rising can make electrical property reduce, and its arc resistance is higher.The chemical resistant properties of PP is good, except strong oxidizer has the erosion action it, other reagent to it all without the effect.PP at room temperature is insoluble to any solvent, but can be at some solvent, and such as swelling in tetracol phenixin, trichloromethane, dithiocarbonic anhydride, the benzene, when temperature raise, PP was dissolvable in water in some solvent.PP is responsive to the effect of oxygen, particularly when temperature is higher.Its ultraviolet-resistant capacity is very poor, also is subject to the destruction of high-energy radiation, when being subject to above-mentioned destruction, and its generation lower-molecular substance of all can degrading.The existence meeting of copper sharply strengthens the oxidative degradation speed of PP, makes its very fast embrittlement, therefore be referred to as " copper evil ".PP has outstanding stress cracking resistance.But its winter hardiness is poor, and weathering resistance is also bad, and high temperature then rigidity is not enough.
Summary of the invention
The deficiency that exists for solving prior art, technical problem to be solved by this invention provides the polypropylene dedicated plastics of a kind of capacitor protector, has higher flame retardant properties.
Technical scheme of the present invention is:
The polypropylene dedicated plastics of a kind of capacitor protector are made of by weight following component: 100 parts of polypropylene, talcum powder 20-30 part, glass fibre 10-20 part, TDE 30-50 part, antioxidant 1010 0.1-0.3 part, lubricant 0.1-0.3 part, HK-550 tensio-active agent 0.2-0.4 part.
Above-mentioned each component is mixed, adopt the ordinary method granulation, can make the polypropylene dedicated plastics of capacitor protector of the present invention.
Glass fibre (English former by name: glass fiber or fiberglass) is a kind of ceramic of excellent performance, of a great variety, advantage is that good insulating, thermotolerance are strong, erosion resistance good, and physical strength is high, but shortcoming is that property is crisp, and wear resistance is relatively poor.It manufactures through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth take glass sphere or discarded glass as raw material, the diameter of its monofilament is that several microns are to twenties meters microns, the 1/20-1/5 that is equivalent to a hairline, every bundle fiber precursor are comprised of hundreds of even thousands of monofilament.Glass fibre is typically used as the strongthener in the matrix material, electrically insulating material and heat-insulating material, the national economy every field such as circuit substrate.
TDE, English name: 1,2-Bis (pentabromophenyl) ethane, CAS number: 84852-53-9, molecular formula: C14H4Br10, its bromine content is high, Heat stability is good, anti-ultraviolet property is good, exudative low than other bromide fire retardants.Do not produce poisonous many bromos dibenzo dioxan DBDO and PBDF DBDF when TDE thermo-cracking or burning, meet Europe fully about the requirement of Dioxins regulations with its fire-retardant material, environment is not worked the mischief.
The polypropylene dedicated plastics of capacitor protector of the present invention's preparation, as a kind of novel thermoplastic reinforced composite, have that Young's modulus is high, intensity is high, heat-drawn wire is high, the advantage such as good stability of the dimension, flame retardant properties are good, the polypropylene dedicated plastics of capacitor protector of the present invention are mainly for the preparation of capacitor protector.
Embodiment:
The polypropylene dedicated plastics of a kind of capacitor protector are made of by weight subordinate's component:
100 kilograms of polypropylene, 25 kilograms of talcum powder, 15 kilograms in glass fibre, 40 kilograms of TDE, 0.2 kilogram of antioxidant 1010,0.2 kilogram of lubricant, 0.3 kilogram in HK-550 tensio-active agent.
Above-mentioned each component is mixed, and melting mixing, extruding pelletization can make the polypropylene dedicated plastics of capacitor protector of the present invention.Mixed processes can carry out in general mixing machine, and the control rotating speed is at 300-400 rev/min, and melting mixing, extruding pelletization operation can be carried out in general screw extrusion press.
After tested: melt flow rate (MFR): 2.8.0 g/10min; Density: 1.18 g/cm3, tensile strength: 42 Mpa, flexural strength: 75 Mpa, heat-drawn wire: 135 ℃, the UL-94 flame retardant rating (1.6mm) is V0, and the LOI value is 31%.
The polypropylene dedicated plastics of capacitor protector of the present invention's preparation, as a kind of novel thermoplastic reinforced composite, have that Young's modulus is high, intensity is high, heat-drawn wire is high, the advantage such as good stability of the dimension, flame retardant properties are good, the polypropylene dedicated plastics of capacitor protector of the present invention are mainly for the preparation of capacitor protector.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
