Mask all-plastic nose bridge strip polyolefin modified material and preparation method thereof

Abstract

The invention discloses a mask all-plastic nose bridge strip polyolefin modified material and a preparation method thereof. The mask all-plastic nose bridge strip polyolefin modified material comprises the following raw materials in parts by weight: 40-75 parts of polyethylene, 5-10 parts of polypropylene, 1-3 parts of a softening agent, 5-20 parts of fibers, 1-2 parts of an anti-aging agent, 0.5-1 part of a lubricating dispersant, 5-10 parts of talcum powder, 1-2 parts of a processing aid, 1-2 parts of a coupling agent and 5-10 parts of a compatilizer. The raw materials of the polyolefin modified material prepared by the preparation process provided by the invention are uniformly dispersed; the polyolefin modified material provided by the invention has excellent physical and chemical properties, has good processability and arbitrary bending and shaping properties after being extruded and processed into a nose bridge strip, is easy to compact and good in shaping effect, has convenientrecoverability and relatively high cost performance, meets the requirements of the current market on the nose bridge strip of the mask, and has good economic benefits.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyolefin modified material of an all-plastic nose bridge strip for a mask and a preparation method thereof. Background technique [0002] The nose bridge strip is a thin strip inside the mask, which plays the role of fixing the mask on the bridge of the nose. At present, the nose bridge strips used for masks mainly include the following types: (1) polyolefin polymer material coated galvanized fine iron wire; (2) metal aluminum sheet; (3) all-plastic nose bridge strips, wherein the metal aluminum sheet has Good bending and shaping characteristics, but this kind of metal nose bridge is not conducive to the separation and recycling of waste masks; polyolefin polymer material coated galvanized thin iron wire is a material widely used by most mask manufacturers at present, and its processing principle Similar to wires and cables, polyolefin polymer materials are used to...

Problems solved by technology

At present, the nose bridge strips used for masks mainly include the following types: (1) polyolefin polymer material coated galvanized fine iron wire; (2) metal aluminum sheet; (3) all-plastic nose bridge strips, wherein the metal aluminum sheet has Good bending and shaping characteristics, but this kind of metal nose bridge is not conducive to the separation and recycling of waste masks; polyolefin polymer material coated galvanized thin iron wire is a material widely used by most mask manufacturers at present, and its processing principle Similar to wires and cables, polyolefin polymer materials are used to coat galvanized thin iron wires with a diameter of 0.45-0.55mm. Molecular materials are difficult to separate, which is not conducive to the separation and recycling of waste masks; while the all-plastic nose strip is mainly made of a single modified polypropylene or modified polyethylene material, which is more and more popular because it is conducive to the separation and recycling of masks. At present, there are still problems such as the all-plastic nose strips are not easy to compress, and the shaping effect is not ideal.
