Abstract
The invention discloses a flame-retardant PE plastic. The flame-retardant PE plastic comprises the following components in parts by weight: 130-135 parts of PE, 10-15 parts of calcium carbonate, 10-20 parts of tribasic lead sulfate, 7-9 parts of phthalate anhydride, 6-9 parts of acrylonitrile, 10-14 parts of alkyl benzene sulfonate, 5-9 parts of dimethyl siloxane, 10-13 parts of ferrocene, 10-15 parts of nano silicon dioxide, 10-15 parts of glass fiber, 10-12 parts of sodium antimonate, 10-15 parts of ammonium polyphosphate and 20-30 parts of triphenyl phosphate. The flame-retardant PE plastic has a good flame-retardant function; an obvious flame-retardant function can be performed when a very small amount of flame-retardant PC plastic is used. The flame-retardant PE plastic does not affect the mechanical strength of a plastic product and particularly does not lower the thermal deformation temperature, the mechanical temperature and the electric insulation property of the plastic product. Meanwhile, the compatibility between the flame-retardant PE plastic and resins is high; the flame-retardant PE plastic does not migrate in the plastic product, and can not be separated out or extracted from the plastic product.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of PE flame retardant plastics.
Technical background
Along with science and technology and economic development, by the daily living article of plastics-production, play in daily life more and more important effect.But the plastics easy firing, and combustionvelocity is fast, can produce a large amount of toxic gases according to statistics, according to statistics, in fire, because of the loss of life and personal injury of suffocating and smoke poisoning causes, accounts for 50~80% of the total casualties of fire.Along with the widespread use of plastics at aspects such as building, furniture, traffic, Aeronautics and Astronautics, electrical equipment, the fire caused due to plastic products also innumerable simultaneously, fire hazard situation allows of no optimist, some fire disaster accidents occur again and again, and be all much that the inflammable materials such as nylon wire, polyurethane foam burn rapidly, shine into the loss of people's casualties and property.Most plastics are all inflammable substances, but all need plastics not burn in the material of construction of plastics, communications and transportation material, home electric appliance material etc., and good flame retardant properties is arranged, and require the degree of being fuming of plastics in big fire little.For this reason, in plastic formula, select to add fire retardant and just become extremely important.Fire retardant is used in the U.S. at first, and after the sixties in 20th century, consumption increases severely, and consumption is only second to softening agent at present.Consuming the maximum plastics variety of fire retardant is polyvinyl chloride, polystyrene, urethane foam, unsaturated polyester, ABS resin and polypropylene.In people's life, at present now a lot of formula of flame-retardant plastics when the material pyrolysis, produce toxic gas cause fire in poison gas and flue gas to the human body side effect that suffocates, grievous injury people's physical and mental health, environmental-protecting performance is very undesirable.In recent years, the higher requirement of the fast development of electronic apparatus, building, aviation and automobile industry to the performance proposition of plastics.Wherein, the plastics of flame retardant type are nonflammable, and rate of flame propagation is little, and mass loss rate and heat release rate are lower, and have certain self-extinguishing.But the flame retardant plastics performance of using at present can not meet the demands, and adopts halogen flame more, combustion processes can be emitted hydrogen halide human body is caused to serious harm.So the selection of fire retardant in plastics, be a very complicated process, must consider above-mentioned every factor.In existing textbook, provided such as: protective membrane mechanism, not so mechanism such as gas mechanism, coolant mechanism and terminating chain lock reactor mechanism; these can select to provide a fuzzy direction to fire retardant, but but can't provide real, effectively help.
Summary of the invention
For above shortcomings in prior art, the object of the invention is to provide a kind of PE flame retardant plastics.
The objective of the invention is to be achieved through the following technical solutions: a kind of PE flame retardant plastics is comprised of the following weight parts component: 130-135 mass parts PE, 10-15 mass parts calcium carbonate, 10-20 mass parts tribasic lead sulfate, 7-9 mass parts phthalate anhydride, 6-9 part vinyl cyanide, 10-14 part benzene sulfonamide acid esters, 5-9 part dimethyl siloxane, 10-13 mass parts ferrocene, 10-15 mass parts nano silicon, 10-15 mass parts glass fibre, 10-12 mass parts metaantimmonic acid are received, 10-15 mass parts ammonium polyphosphate and 20-30 mass parts triphenylphosphate.
The beneficial effect that the present invention has: the PE flame retardant plastics that the present invention makes has good anti-flaming function, and consumption seldom just can obviously play fire retardation; And do not affect the physical strength of plastics, particularly do not reduce heat-drawn wire, mechanics temperature and the electrical insulation capability of plastics; To get well with the consistency of resin, do not move in plastics, do not separate out, be not extracted simultaneously.
Embodiment
Example of the present invention is can not limit the present invention to explanation of the present invention, in the implication suitable with the present invention and any change and the adjustment in scope, all should think within the scope of the invention.
embodiment 1
The preparation of PE flame retardant plastics: by 130-135 mass parts PE, 10-15 mass parts calcium carbonate, 10-20 mass parts tribasic lead sulfate, 7-9 mass parts phthalate anhydride, 6-9 part vinyl cyanide, 10-14 part benzene sulfonamide acid esters, 5-9 part dimethyl siloxane, 10-13 mass parts ferrocene, 10-15 mass parts nano silicon, 10-15 mass parts glass fibre, 10-12 mass parts metaantimmonic acid is received, 10-15 mass parts ammonium polyphosphate and 20-30 mass parts triphenylphosphate mix puts into stirrer, put into the Banbury mixer banburying after stirring, the internally mix temperature is 180-185 ℃, rotating speed is 1100-1150rpm, then by the mixture after banburying through granulator granulation, obtain particle, particle is put into to tank cooling, then dry at normal temperatures, the salient features of the material that the present embodiment is prepared is as follows: tensile strength MPa(GB/T1040-2006): 39-41, elongation at break %(GB/T 1040-2006): 6-8, shock strength kJ/m
2(GB/T1043-2008): 4-5, flexural strength MPa(GB/T9341-2000): 46, oxygen index % (GB/T2406-1993): 36, vertical combustion rank UL-94: V0.Thermotolerance and the flame retardant resistance of flame retardant plastics of the present invention are more excellent, and preparation technology is simple, and product cost is low, and the over-all properties of product is more excellent.
