Development speed, scale and the technical level in field are obviously improved, high molecular material with its designability, high production efficiency,
The features such as lightweight, energy conservation, is widely used.
The molecular weight of polypropylene (Polypropylene, PP) is about 8~150,000, its molecular structure determines that it has
Lower water imbibition, water absorption rate are only 0.01%.The highly crystallized due to polyacrylic molecular structure rule, so poly- third
The fusing point of alkene is up to 164~170 DEG C.It also has that relative density is small, transparent, lustrous surface is good, harmonious good, resistance toization of mechanics
Learn burn into is easy to process, heat distortion temperature is high, abundance and the prominent advantage such as cheap and quickly grow.It is wide at present
General applies in fields such as industrial construction, auto industry, electric, packaging and building materials.Polyacrylic mechanical property is slightly above
Polyethylene, and polyacrylic chemical stability is also fine, other than it can be corroded by the concentrated sulfuric acid, concentrated nitric acid, to various otherization
It is all more stable to learn reagent, but the aliphatic hydrocarbon of low molecular weight, aromatic hydrocarbon and chlorinated hydrocabon etc. can make polypropylene soften and be swollen, simultaneously
Its chemical stability can also increase with the increase of crystallinity.
Since polypropylene only has carbon, two kinds of elements of hydrogen are constituted, and it is active containing being connected with tertiary carbon atom in strand
Hydrogen atom leads to be easy to happen oxidation reaction under hot oxygen environment generating free radicals and making molecular chain rupture, so easily burn,
Its limit oxygen index is 17% or so, belongs to combustible material, is not easy into charcoal in combustion, with a large amount of dense smokes and melting
Drippage, limits its promotion and application.Conventional polypropylene is fire-retardant to mostly use halogen system flame-retardant system greatly, although halogen system flame-retardant system has
Have that additive amount is few, the obvious feature of flame retardant effect, but after adding halogen system flame-retardant system, can be generated in burning it is a large amount of it is toxic, have
Corrosive smog not only seriously pollutes environment, does not meet the theory of environmental protection, and interferes withdrawing and rescuing for scene of fire personnel
The expansion for helping work constitutes potential threaten to human life's safety and living environment.Therefore it is badly in need of a kind of resistance of high-efficiency environment friendly
The polypropylene material of combustion type.
Summary of the invention
In order to overcome the defect in the presence of the prior art, the present invention provides a kind of system of highly effective flame-retardant type polypropylene material
Preparation Method.
The technical solution adopted by the present invention to solve the technical problems is: a kind of preparation of highly effective flame-retardant type polypropylene material
Method, the highly effective flame-retardant type polypropylene material includes following components by weight: 100 parts of polypropylene, 1~3 part of polyethylene wax,
