A kind of PTFE material for glass fiber coating clustering device and preparation method

Abstract

The invention discloses a PTFE (Polytetrafluoroethylene) material for a glass fiber coating and bundling device. The PTFE material is prepared from the following components in parts by mass: 70 to 100parts of polytetrafluoroethylene (PTFE), 0 to 30 parts of modified polytetrafluoroethylene, 1 to 60 parts of wear-resisting filler and 1 to 60 parts of high-temperature-resisting resin. The PTFE material disclosed by the invention has the advantages of abrasion resistance, high temperature resistance, low friction coefficient, hydrophilic and lipophilic performance, corrosion resistance and the like. Compared with original graphitic oil coating roller and bundling wheel, the abrasion of a product can be reduced, the service life of the product is prolonged and the pollution, caused by the product, to glass fibers is reduced; and the hairiness generated in a glass fiber production process is reduced and the quality of the glass fibers is improved. Being different from other PTFE surface hydrophilic modification methods, an inner material of an oil coating roller product prepared from the PTFE material still has very good hydrophilic performance under the condition that a surface material is abraded, and the coating uniformity of an impregnating agent in a working process is ensured.

Description

technical field [0001] The invention belongs to the field of glass fiber coating and clustering devices, in particular to a PTFE material used for glass fiber coating and clustering devices. Background technique [0002] In the process of glass fiber production, after the high-temperature molten glass flows out of the nozzle, it needs to be impregnated with different formulations of sizing agent through the oiling roller device, and then gathered by the cluster wheel and finally wound on the raw wire forming equipment to form glass fiber products of suitable thickness. . The quality level of the glass fiber is largely determined by the coating bundle unit, which consists of an oiling roller unit and a bunching wheel unit. Oiling rollers in the glass fiber industry work in a high-temperature and high-humidity environment. The glass fiber and sizing agent need to be clean and pollution-free, and can be recycled and reused, and are easy to clean with solvents and lathe turning...
