Problems solved by technology

[0002] Existing paper tubes are mainly used as winding cores for spinning, felting and other industries. Existing paper tubes have many defects: low compressive strength, and easy deformation of paper tubes during high-speed operation, which affects industrial production. Efficiency; high water absorption rate and easy to be damaged by moisture, resulting in short service life; easy to expand, poor dimensional stability, difficult to replace, easy to lead to product scrapping; as a flammable material, once it catches fire, it is easy to cause spread and poor safety; and the paper tube Use wood as raw material, waste of resources; loud noise during operation, poor environmental protection

Abstract

The invention discloses a plastic turnover pipe replacing a paper tube for chemical fiber spinning. The plastic turnover pipe is prepared from the following raw materials in parts by weight: 60-90 parts of matrix resin, 10-40 parts of a flexibilizer, 0.2-0.5 part of an antioxidant, 0-5 parts of color master batch, 1-2 parts of zinc borate, 0.4-1 part of calcium ricinoleate, 1-2 parts of barium stearate, 0.5-1 part of 2-mercapto benzimidazole, 2-3 parts of polytetrafluoroethylene wax, 7-9 parts of aluminum isopropoxide, 4-10 parts of carbon nano tubes, 0.8-1 part of fatty acid diethanol amide and 0.06-0.1 part of zinc oleate. According to the invention, the matrix resin is used as a main ingredient; the prepared plastic turnover pipe is used for replacing the traditional paper tube; the plastic turnover pipe has the advantages of long service life, high stability, high compressive strength and excellent fire resistance.

Description

technical field [0001] The invention belongs to the field of textile machinery, and in particular relates to a plastic turnover tube used for chemical fiber spinning instead of a paper tube and a preparation method thereof. Background technique [0002] Existing paper tubes are mainly used as winding cores for spinning, felting and other industries. Existing paper tubes have many defects: low compressive strength, and easy deformation of paper tubes during high-speed operation, which affects industrial production. Efficiency; high water absorption rate and easy to be damaged by moisture, resulting in short service life; easy to expand, poor dimensional stability, difficult to replace, easy to lead to product scrapping; as a flammable material, once it catches fire, it is easy to cause spread and poor safety; and the paper tube Using wood as raw material is a waste of resources; it is noisy during operation and poor in environmental protection. Therefore, in order to improve...
