The preparation method of halogen-free flame retarding plastic fabric material includes the steps as follows: the 30-60wt percent of magnesium salt mineral, the 5-10wt percent of supporting flame retardant, the 50-70wt percent of resin, the 5-10wt percent of compatibilizer, and the 5-15wt percent of internal lubricant are put in a stirring mill and mixed for 10 minutes, and then the mixed material is pelletized in a double-screw extruder, the temperature at the feeding section of the extruder is 60-90 DEG C and the temperature at the measuring section is 110-190 DEG C as required; the halogen-free flame retarding plastic fabric material is fabricated after the pelletization.

Description

A kind of halogen-free flame retarding plastic fabric material and preparation method thereof
Technical field:
The present invention relates to a kind of halogen-free flame retarding plastic fabric material and preparation method thereof.
Background technology:
Halogen-free flameproof is one of current plastic functional development trend, also is abroad to moulding an important indicator compiling product evaluation.Product performance and safety, environmental protection, health are had higher requirement.It is more and more higher to the requirement of packing bag particularly to consume the client abroad, should the U.S. fashion of refinement require nontoxic, fire-retardant again.
Non-halogen Flame Retardant Technology development at present is that the halogen-free flame retardants of representative is applied in the plastics with magnesium, boron compound rapidly, but the report as yet of the application in plastic woven material is comparatively harsh mainly due to the follow-up Wire Drawing of plastic woven material.
Summary of the invention:
The present invention is exactly at the problems referred to above; provide a kind of employing to contain magnesium or contain the aluminium inorganics as being the oxyhydroxide of aluminium, magnesium, molybdenum etc. and the hydrate of oxide compound; be aided with stibnide, borides inorganics and polyolefin resin blend; the consistency of carrying out the granulation acquisition is good, can carry out accurate stringy halogen-free flame retarding plastic fabric material and preparation method thereof.
For achieving the above object, the present invention adopts following technical scheme:
A kind of halogen-free flame retarding plastic fabric material comprises following component:
Magnesium salts inorganics 30 wt%-60wt%;
Auxiliary flame retardant 5wt%-10wt%;
Resin 50wt%-70wt%;
Expanding material 5wt%-10wt%;
Internal lubricant 5wt%-15wt%.
A kind of preparation method of halogen-free flame retarding plastic fabric material, its step is as follows:
Get magnesium salts inorganics 30wt%-60wt%; Auxiliary flame retardant 5wt%-10wt%; Resin 50wt%-70wt%; Expanding material 5wt%-10wt%; Internal lubricant 5wt%-15wt%; Above-mentioned raw materials was put into high-speed mixer and mixing 10 minutes, then with compound granulation in twin screw extruder, require 60 ℃-90 ℃ of forcing machine feeding section temperature, 110 ℃-190 ℃ of the temperature of metering zone can obtain halogen-free flame retarding plastic fabric material of the present invention after the granulation.
Beneficial effect of the present invention:
The present invention with the polyolefin plastics resin alloy, brings into play its synergistic effect with magnesium hydroxide and zinc borate halogen-free flame retardants and auxiliary flame retardant, not only obtains good flame retardancy, and has effectively controlled the discharge of toxic gas in the burning; Adopt superpolymer expanding material and silane coupling agent expanding material, guaranteed that the Physical Mechanical loss of energys such as tensile strength of material are less; Can guarantee to mould the smooth implementation of compiling drawing process, effectively reduce raw-material cost.Realize that product is nontoxic, tasteless, the protection environment.And the present invention has overcome existing inorganic combustion inhibitor and has caused moulding the shortcoming of compiling the material mechanical properties decrease by effective increase-volume.Technology is simple, and operation is easily gone, and has good wire drawing and flame retardant effect as plastic woven material.
