Abstract

The invention discloses a manufacturing method of a high-acid-base-resistance non-woven material for a wringing roller. The manufacturing method comprises the following steps of firstly, weighing 70-90% of high-strength polypropylene fibers and 10-30% of ultrahigh-molecular-weight polyethylene fibers in percentage by mass; mixing the high-strength polypropylene fibers with the ultra-high-molecular-weight polyethylene fibers to form mixed fibers; opening and mixing the mixed fibers in sequence by adopting an opener to obtain pretreated mixed fibers; carding the pretreated mixed fibers by adopting a carding machine, and performing dry laying to obtain a fiber web; needling and reinforcing the fiber web to obtain a high-strength polypropylene / ultra-high-molecular-weight polyethylene fiber needled felt; and impregnating the high-strength polypropylene / ultra-high-molecular-weight polyethylene fiber needled felt with a hydrophilic high-acid-alkali-resistance adhesive, performing drying in adrying oven, and performing natural cooling to room temperature so as to obtain the high-acid-alkali-resistance non-woven material for the wringing roller. The problems that in the prior art, a non-woven fabric wringing roller is poor in acid and alkali resistance and low in strength are solved.

Description

technical field [0001] The invention belongs to the technical field of nonwoven textile processing, and in particular relates to a method for manufacturing a high acid and alkali resistant nonwoven material for a squeeze roller. Background technique [0002] Metal strip intermediate and finished cleaning is the most important production process to improve the surface quality of the strip. After cleaning plates such as copper and copper alloy plates with liquid media such as acid and alkali, it is also necessary to remove the liquid on the surface of the plates. At present, squeezing rollers are mostly used to remove excess acid, alkali and other liquids on the surface of the board. [0003] Compared with the traditional drying roller, the non-woven fabric squeeze roller has the following advantages: (1) The non-woven fabric layer can be self-healing and easy to replace; when the damage is small, it has self-healing ability under a certain pressure; When it is too large, it...
