Background technology
With continuing to develop for industry, plastics are increasingly widely applied.Polyethylene, polypropylene, PTT polyester, ABS
Etc. it is a large amount of using in industries such as water-saving irrigation, building, indoor decoration, furniture, electric power, transports.But carbon, hydrogen two in plastics
Plant constituent content very high, so being easy to burning, thus limit the use of plastics.All need to carry out when generally using plastics fire-retardant
Treatment.Based on the main fire retardant of addition in addition fire-retardant at present.Flame retardant treatment is carried out to material using outer addition fire retardant mode, its
Flame retarding efficiency is high, technology maturation, cheap, but the general content of halogen of fire retardant of addition is higher, and during burning, plastics are heated and release
Halogen flue gas is released, with toxicity, the health of meeting harmful to human, or even personnel death is caused；Fire retardant addition is big, to material
The post-production influence of itself is larger, and fire retardant is easily separated out and can not for a long time keep anti-flammability, shortens service life.
The content of the invention
It is an object of the invention to overcome the above-mentioned deficiency in the presence of prior art, there is provided a kind of high tenacity is flame-retardant modified

30min, adds salicylic acid -4- tert-butyl groups phenyl ester, dilauryl thiodipropionate, dioctyl phthalate, three oxidations two
Antimony and OPE, continue to mix 5-10min, rotating speed 500-800r/min, are subsequently added a nanometer potassium feldspar, nanometer
Medical stone, titanate coupling agent and 2-Butoxyethyl acetate, mix 10-16min；
(3) compound for obtaining step (2) kneads 9-13min, 133-145 DEG C of melting temperature with roll squeezer；
(4) mixture that step (3) is obtained is placed in extruding pelletization in Bitruder, temperature control is in 150-165 DEG C, spiral shell
Bar rotating speed 20-40r/min；
(5) the pellet injection moulding for obtaining step (4), 160-180 DEG C of feeding temperature, 160-180 DEG C of drop temperature, injection pressure
Power 80-90MPa.
Compared with prior art, beneficial effects of the present invention：
The modified plastics that the present invention is provided, it is nontoxic, there is toughness stability high and preferable and flame retardant effect
Good, content of halogen is low, without outer addition fire retardant, breaches the defect of traditional flame retardant plastics, with very strong practical value, in addition
Preparation method of the invention is simple, with low cost, is adapted to industrialized production.
