Abstract
The invention discloses a kind of high-strength high-glowing-filament-temperature flame-retardancy polypropylene and preparation method thereof, and it includes consisting of that high-strength high-glowing-filament-temperature flame-retardancy polypropylene is calculated as mass fraction：Polypropylene 39~66.5%, bromide fire retardant 10~20%, nitrogen phosphorus fire retardant 10~20%, antimony oxide 3~5%, long glass fibres 10~15%, antioxidant 0.5~1%.Polyacrylic flame retardant property is effectively improved using bromide fire retardant, nitrogen phosphorus fire retardant simultaneously, glowing filament ignition temperature is up to 850 DEG C；And so that polypropylene flame redardant is impregnated long glass fibres using melt impregnation, the draw ratio of fiber can be effectively kept, glass fibre is utmostly played to the humidification of matrix, is prepared for high-strength high-glowing-filament-temperature flame-retardancy polypropylene.
Description
Technical field
The present invention relates to modifying plastics fields, and in particular to a kind of high-strength high-glowing-filament-temperature flame-retardancy PP composite material.
Background technology
Polypropylene（PP）It is one of five big general-purpose plastics, there is nontoxic, light, corrosion-resistant, easy to process, production cost
The features such as low, Good Heat-resistance, electrical breakdown withstand are had excellent performance, is therefore widely used in production and sphere of life.But PP
The limit oxygen index of resin is very low, and molten drop is serious when belonging to combustible material, and burning, and easy propagating flame causes fire, and
The mechanical property of PP materials is relatively low compared with other plastics, and PP is caused to be restricted in the application in many fields.
Electronics and electrical equipment industry evaluate electronics and electric appliance plastic needle using 94 standards of U.S. UL always for many years
To the dynamic flame-retarding to catch fire, but since electronics and electrical equipment Inner plastic component are in use because of poor contact, mistake
Carry, short circuit and overheat, the caused fire that actively catches fire but frequently occurs, International Power association of European Union（IEC）Start requirement industry
Also execute more stringent 60695 glowing filament flame retardant test evaluation criterions of IEC simultaneously, IEC groups be woven in 60335 households of IEC and
Itd is proposed in similar security appliance standard long-term unattended electric appliance must simultaneously meet UL using the flame retardant property of plastic part
Not on fire or burning time is less than 5 s, i.e. glowing filament ignition temperature in 94V-0 grades and 750 DEG C of glowing filament contact material 30s
（GWIT）More than 750 DEG C.GWIT temperature is then also required for particular elements such as connector, contact-making switch, motor and Shell of circuit breaker
850 DEG C of degree and the flammable index of glowing filament（GWFI）950℃.
102336970 B of patent CN disclose a kind of 850 DEG C of nonflammable PP composite materials of glowing filament and its preparation side
Method, the composite material include by weight：100 parts of polypropylene, 45~50 parts of compound flame retardant；Wherein compound flame retardant is under
Row composition by weight is constituted：100 parts of ammonium polyphosphate, 40~60 parts of microencapsulation three-(2,3- dibromopropyl) chlorinated isocyanurates, trimerization
40~60 parts of cyanamide, glowing filament ignition temperature reach 850 DEG C or more, 18~19 MPa of tensile strength.
102558674 B of patent CN disclose a kind of flame-proof polypropelene composition with high glowing filament ignition temperature, should
Using bromide fire retardant, fire retarding synergist, high-efficiency compound fire-proof agent collectively as fire retardant, the material glowing filament rises composition
Fire temperature（GWIT）Meet the requirement higher than 750 DEG C.
103122101 B of patent CN disclose a kind of nonflammable PP composite material of high glow-wire and its production method,
The component of the material and the parts by weight of each component are 100 parts of polypropylene, 5~10 parts of compound flame retardant, wherein compound flame retardant group
Divide and the parts by weight of component are 100 parts of the milled glass fiber of 5~10 parts of radical initiator, grain size less than 2.86 μm, micro- glue
2~8 parts of 10~30 parts of 35~70 parts of hydrobromate fire retardant, silicone polymer, the magnesium stearate of package, the composite material is scorching hot
Silk initiation temperature（GWIT）More than 775 DEG C.
102942739 B of patent CN disclose a kind of high CTI value, high GWIT values environment-protection flame-proof fiberglass enhancing PP materials and
Preparation method, the composite material use halogen and halogen-free flameproof compound system, and using melt-blending process, the material of preparation is scorching hot
800 DEG C of silk ignition index reached or more.
105778281 A of patent CN disclose a kind of high glow-wire, low-smoke flame-retardant polypropylene alkene composite material and its preparation side
Method, the composite material are made from the following raw materials in parts by weight：100 parts of polypropylene, 5-10 parts of hypophosphites, the poly- phosphorus of melamine
15-20 parts of hydrochlorate, 1-3 parts of porous aluminum silicon inorganic matter, 3-10 parts of maleic anhydride inoculated polypropylene, antioxidant PS802 0.2-1.2
Part, 0.2-1.0 parts of irgasfos 168/1010,0.5-3.0 parts of lubricant SG200,5-10 parts of white oil.Prepared polypropylene is multiple
Condensation material has high glowing filament ignition temperature (GWIT >=850 DEG C), strong mechanical performance（The MPa of tensile strength >=20.5）, low hair
The advantages of smoke, low-heat ball impression (125 DEG C≤1.7mm), resistance to precipitation, excellent fireproof performance.
Existing to be related to the related technology that polypropylene glowing filament is fire-retardant, enhancing is fire-retardant, the fire-retardant research of simple glowing filament cannot
Take the promotion of material mechanical performance into account, and uses glass fiber reinforced flame retardant is polyacrylic to mostly use melt-blending process preparation, warp
After crossing twin-screw shearing, fiber is grated, and draw ratio is small, and higher additive amount is needed to can be only achieved the effect of enhancing, Er Qiegao
The fiber of content, which is also given to squeeze out to process, brings difficulty, and fiber easily causes raw material and fire retardant to decompose with barrel friction.This technology
It is effectively improved polyacrylic using the synergistic effect of different system fire retardants using nitrogen phosphorus fire retardant, bromide fire retardant simultaneously
Flame retardant property obtains high glowing filament ignition temperature, and, this patent different from existing polypropylene fire retardant, enhancing modification technology
Long glass fibres method is impregnated using polypropylene flame redardant, having been prepared under conditions of relatively low fire retardant and content of glass fiber has
High intensity, the enhancing of high glowing filament ignition temperature, flame retardation modification polypropylene compound composite material ensure that effective length of reinforcing fiber
Degree utmostly plays humidification of the glass fibre to matrix.
