Abstract
The invention discloses a kind of anti-dripping melt transparent flame-retarding TPU materials and preparation method thereof.Present invention discover that halogen-free flame retardants DIDOPO not only good fluidities, TPU is carried out using DIDOPO fire-retardant, TPU/DIDOPO fire proofings not only excellent fireproof performance, and the transparency of TPU/DIDOPO fire proofings is not affected, fire-retardant synergistic is not only played a part of to TPU/DIDOPO fire proofings the transparent synergist added simultaneously after, there is antireflective effect to TPU/DIDOPO fire proofings simultaneously, but TPU/DIDOPO fire proofings are easily dripped.Therefore, applicant has found that anti-dripping agent PTFE is to utilize fibrosis of the polytetrafluoroethylene polymer in plastic processing by studying, and heat shrinkable plays anti-drip effect, reduces spreading for flame.Anti-dripping agent PTFE is added in TPU/DIDOPO fire proofings increases the melt strength and slump resistance of polymer, so as to improve the fire-retardant anti-dripping melts of TPU/DIDOPO.
Description
Technical field
The present invention relates to technical field of polymer materials, especially a kind of anti-dripping melt transparent flame-retarding TPU materials and its preparation
Method.
Background technology
TPU full name are TPUE rubber, are broadly divided into polyester-type and polyether-type.At present, TPU is extensive
In terms of health care, electronic apparatus, industry and physical culture, it has the incomparable intensity of other plastic materials
The characteristic such as height, good toughness, wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant, weatherability, while he has high water proofing property penetrability, prevented
Many excellent functions such as wind, cold-proof, antibacterial, mould proof, warming, uvioresistant and energy release.Halogen-free flameproof TPU can be with
Instead of flexible PVC to meet the environmental requirement in more and more fields.
The fire-retardant TPU resins of halogen flame are without the transparency.Therefore, the application of halogen system flame retardant products is restricted.
Nitrogenated flame retardant is cheap in fire-retardant TPU fields attention due to flame retarding efficiency height.But existing melamine cyanurea
The fire-retardant TPU resins of hydrochlorate, melamine (poly-) phosphate are all without the transparency.
The content of the invention
The purpose of the present invention is：A kind of anti-dripping melt transparent flame-retarding TPU materials and preparation method thereof, its preparation method work are provided
Skill is simple, and fire retardant is uniformly dispersed, and prepares less energy consumption, and flame retardant effect is excellent, excellent transparency, and does not drip, and combination property is excellent
It is different, and the feature of environmental protection is good, to overcome the deficiencies in the prior art.
What the present invention was realized in：Anti-dripping melt transparent flame-retarding TPU materials, are calculated according to the mass fraction, wrap 85~95 parts of heat
Plastic polyurethane elastomer, 6~13 parts of fire retardant DIDOPO, 0.1~0.3 part of anti-dripping agent, 0.5 part of antioxidant and 0.1 part are thoroughly
Bright fire retarding synergist is preparing raw material.
Described fire retardant DIDOPO is the miscellaneous -10- phospho hetero phenanthrenes -10- oxides of the 10- dihydro-9-oxies of phenethyl bridge chain 9 '；
DIDOPO melting temperature is 180 DEG C, and decomposition temperature is 360 DEG C, and DIDOPO structural formulas are：
Described anti-dripping agent is anti-dripping agent PTFE.
Described antioxidant is antioxidant 1010.
Described transparent flame-retarding synergist is organic silicon flame-retardant synergist.
The preparation method of anti-dripping melt transparent flame-retarding TPU materials, by above-mentioned parts by weight, take TPUE,
DIDOPO, anti-dripping agent, transparent flame-retarding synergist and antioxidant are separately dried standby；Above-mentioned dried each component is mixed equal
It is even, blending extrusion is carried out, processing temperature is：180-210 DEG C, through cooling, traction, pelletizing, obtain anti-dripping melt transparent flame-retarding TPU materials
Material.
By adopting the above-described technical solution, compared with prior art, present invention discover that halogen-free flame retardants DIDOPO is not only
Good fluidity, fire-retardant, TPU/DIDOPO fire proofings not only excellent fireproof performance, and TPU/ is carried out using DIDOPO to TPU
The transparency of DIDOPO fire proofings is not affected, while to TPU/DIDOPO fire proofings after the transparent synergist added
Not only play a part of fire-retardant synergistic, while there is antireflective effect to TPU/DIDOPO fire proofings, but TPU/DIDOPO hinders
Combustible material is easily dripped.Therefore, applicant has found that anti-dripping agent PTFE is in plastics using polytetrafluoroethylene polymer by studying
Fibrosis in processing, heat shrinkable plays anti-drip effect, reduces spreading for flame.In TPU/DIDOPO fire proofings
The middle anti-dripping agent PTFE that adds increases the melt strength and slump resistance of polymer, so as to improve the fire-retardant anti-drops of TPU/DIDOPO
Fall.Extensively, the feature of environmental protection is good for material source of the present invention, and using effect is preferable.
