The invention discloses a PE-PET alloy material and a preparation method and application thereof. PE-PET alloy materials include the following raw materials by mass percentage: 40%-70% PE, 20%-40% PET, 3%-10% inorganic micro-nano filling powder, 3%-10% compatibilizer and 1% to 5% additives. The alloy material of the invention synergistically controls the content of the two components PE and PET and their compatibility with other components, wherein the amount of PE ensures that the elongation at break under high-speed stretching meets the requirements, and the content of PET ensures that downstream customers are The produced nose bridge strip is folded in half and the rebound angle requirements meet the rigid-tough balance required for the full plastic nose bridge strip material. The elongation at break of the material is more than 500% under high-speed stretching, which is suitable for downstream customers to extrude at high speed without occurrence. In the case of broken strips, the nose bridge strips produced by downstream customers have a rebound angle of ≤15° after being folded in half, which can be widely used in the preparation of disposable mask nose bridge strips. |
