Abstract

The invention relates to a surface treating agent and a surface treating process of a piece of glass fiber filter cloth, belonging to the technical field of the surface treating agent of the glass fiber. The surface treating agent disclosed by the invention comprises 8-15% of PTFE (Polytetrafluoroethylene) dispersing agent, 5-10% of emulsion type high-temperature softening agent, 1-2% of inorganic antistatic agent, 0.5-1% of penetrating agent, 1-2% of silane coupling agent, 0.5-1% of fluorocarbon surfactant and the balance of softened water. The glass fiber filter cloth produced after the treatment of the surface treating agent solves the problems that the corrosion resistance is poor and the air permeability is large in the prior art, and has the advantages that the surface colors are uniform, the flexibility is good, the folding number is large, the air permeability is moderate, and the service life is long.

Description

technical field [0001] The invention relates to a surface treatment agent and a treatment process using the treatment agent, more specifically, the invention relates to a surface treatment agent for glass fiber filter cloth and a surface treatment process for glass fiber filter cloth, belonging to the glass fiber surface treatment agent technology field. Background technique [0002] Glass fiber filter material has the advantages of high strength, stable size, high temperature resistance, good corrosion resistance and high filtration efficiency, but glass fiber also has obvious disadvantages, that is, it is brittle, not resistant to folding, and not wear-resistant. Gray, easy to wear and break, affecting service life. The quality of the surface treatment of glass fiber filter cloth has a great difference in improving the properties of folding resistance, wear resistance and water repellency. Each link is of great significance to improving the performance of the product. ...
