Abstract

The invention discloses a preparation method of a military oil storage bag TPU composite material. The military oil storage bag TPU composite material is prepared through the steps that a thermoplastic polyurethane elastomer (TPU) and polyamide 6 (PA6) are taken as a matrix, a self-prepared compatibilizer (EVA-g-MAH) is adopted to reduce interfacial tension between the TPU and the PA6, the system compatibility is improved, ATO powder is taken as an antistatic agent, modified MH is taken as a flame retardant, a combined anti-aging and anti-yellowing agent is processed through melt blending and then processed through extrusion pelletizing, and calendaring molding is performed to prepare the military oil storage bag TPU composite material with the excellent property. According to the preparation method, by adding the compatibilizer, the TPU and the PA6 are blended to prepare alloy with the excellent comprehensive property to achieve the purpose of reducing the cost of only using the TPU material; meanwhile, the prepared military oil storage bag TPU composite material has the good antistatic property and flame-retardant property, and through the synergistic effect of the combined anti-aging and anti-yellowing agent, the defect that the TPU is prone to be aged and yellowed is overcome.

Description

technical field [0001] The invention belongs to the technical field of polymer composite film preparation, and in particular relates to a military oil storage bag TPU composite material and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) is composed of diisocyanate, polyol and short chain diol, which can be plasticized by heating and can be dissolved by solvent (AB) n type block linear polymers. Polyurethane is a polymer material with a wide range of uses, mainly used in automobiles, construction, paving materials, mining, mining, electronics and aerospace. In recent years, as one of the important chemical reinforcement materials, polyurethane grouting material has developed rapidly. And people have turned their attention to TPU water storage bags, TPU military oil storage bags, TPU wading products, etc. [0003] Using TPU as a military oil storage bag is an ideal choice to replace hard oil tanks in the future.
