Abstract

The invention discloses an anti-dripping transparent flame-retardant TPU material and a preparation method thereof. The effects that halogen-free flame retardants DIDOPO have high flowability; when the DIDOPO is used for achieving flame-retardant effects on the TPU, the TPU / DIDOPO flame-retardant material has excellent flame-retardant performance; the transparency of the TPU / DIDOPO flame-retardant material is not influenced; meanwhile, after the addition of transparent synergists, the flame-retardant synergistic effect is achieved on the TPU / DIDOPO flame-retardant material; meanwhile, the anti-reflection effect is achieved on the TPU / DIDOPO flame-retardant material, but the TPU / DIDOPO flame-retardant material can easily drip and fall are discovered. Therefore, the applicant discovers that the anti-dripping agent PTFE achieves an anti-dripping effect through the heated shrinkage by using the fibrillation of polytetrafluoroethylene polymers in the plastic processing process through the study; the flame spreading is reduced. When the anti-dripping agent PTFE is added into the TPU / DIDOPO flame-retardant material, the melt strength and the collapse resistance performance of the polymers are improved, so that the flame-retardant and anti-dripping performance of the TPU / DIDOPO is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an anti-dripping transparent flame-retardant TPU material and a preparation method thereof. Background technique [0002] The full name of TPU is thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. At present, TPU has been widely used in medical and health care, electronic appliances, industry and sports, etc. It has high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance and other characteristics unmatched by other plastic materials. At the same time, it has many excellent functions such as high waterproof and moisture permeability, windproof, cold proof, antibacterial, mildew proof, warm keeping, UV resistance and energy release. Halogen-free flame-retardant TPU can also replace soft PVC to meet environmental protection requirements...
