Abstract

The invention relates to a plastic mask nose bridge batten which comprises the following material components in percentage by weight: 75-85% of polypropylene, 14-22% of polyvinyl chloride (PVC) and 1-3% of setting agent. The plastic mask nose bridge batten is formed by utilizing a screw extruder to carrying out pulling and winding. The plastic mask nose bridge batten of the invention replaces the original metallic nose bridge batten and is especially suitable for being used in dry battery plants, coal mining fields and other occasions capable of generating strong static electricity easily.

Description

technical field [0001] The invention relates to a nose bridge pressing strip, in particular to a plastic mask nose bridge pressing strip. Background technique [0002] At present, the commonly used mask nose bridge strip is basically a metal product, and its disadvantage is that it will break after repeated continuous bending; it is used in dry battery factories, coal mining fields and other places where strong static electricity is likely to be generated, and electric shocks and sparks will occur, which is safe. The coefficient is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plastic mask nose bridge layer that improves safety and is not easily broken after repeated bending. [0004] In order to solve the above technical problems, the invention provides a plastic mask nose bridge layer, the material components of the layer are (by weight): polypropylene is 75 to 85%, polyvinyl chloride PVC is 14 to 22%...
