Abstract
The present invention relates to a kind of modified Nano plastics and preparation method thereof, it is made up of the material of following portions by weight: plastics 40-60 part, antioxidant 10-15 part, polybutylene terephthalate 5-20 part, nano flame retardant mixture 25-30 part, ferric oxide 5-15 part, Isosorbide-5-Nitrae-butylene glycol 5-10 part.The present invention burn release flue gas few, long service life, is comparatively widely used in the fields such as building, indoor decoration.
Description
Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of modified Nano plastics and preparation method thereof.
Background technology
Along with the development of industry, plastics obtain applying more and more widely.Polyethylene, polypropylene, PTT polyester, ABS etc. are used in the industries such as water saving irrigation, building, indoor decoration, furniture, electric power, transport in a large number.But the carbon in plastics, hydrogen two kinds of constituent contents are very high, so as easy as rolling off a log burning, thus limit the use of plastics.All need during general use plastics to carry out fire-retardant finish.The current fire-retardant main fire retardant of interpolation is in addition main.Adopt outer fire retardant mode of adding to carry out fire-retardant finish to material, its flame retarding efficiency is high, technology maturation, low price, but the general content of halogen of fire retardant added is higher, and during burning, plastics are heated and discharge Halogen flue gas, have toxicity, the health of meeting harmful to human, even causes personnel death; Fire retardant addition is large, comparatively large on the post-production impact of material itself, and fire retardant is easily separated out and can not be kept flame retardant resistance for a long time, shortens work-ing life.
Summary of the invention
The object of invention is to provide modified Nano plastics of a kind of smokeless, long service life and preparation method thereof.
In order to realize object of the present invention; the invention provides a kind of modified Nano plastics; it is made up of the material of following portions by weight: plastics 40-60 part, antioxidant 10-15 part, polybutylene terephthalate 5-20 part, ferric oxide 5-15 part; 1; 4-butylene glycol 5-10 part, nano flame retardant mixture 25-30 part;
The preparation method of described nano flame retardant recombiner is:

Further improvement, composite flame-retardant agent is one or more in halohydrocarbon, organic bromide, organic chloride, phosphoric acid ester, nitrogenated flame retardant;
Further improvement, also comprises weisspiessglanz 5-8 part in described modified Nano plastics;
Further improvement, also comprises zinc borate 5-8 part in described modified Nano plastics;
The present invention also provides a kind of preparation method of modified Nano plastics, the steps include:
Weigh, each composition is proportionally weighed;
Stir, vacuum stirring 10-30 minute at above-mentioned each composition is placed in 40-60 DEG C;
Mixing, by the above-mentioned each composition mixed melting mixing in two roller mill, temperature is 120-160 DEG C;
Shaping, after repeatedly mixing on a mill until, the composition mixed is conveyed into extruding granulator, for subsequent use through granulating and forming.
Beneficial effect: after the component mixing that the present invention adopts, can be fire-retardant preferably, and less by heat release flue gas, little to human body infringement; Fire retardant is not easily separated out, long service life.
