Salt-resistant water-absorption water-diversion polymeric membrane

Abstract

The invention relates to a polymeric membrane. The polymeric membrane comprises a base membrane body (1). The polymeric membrane is characterized in that the surface of the base membrane body (1) is coated with a polypropylene coating (2); the polypropylene coating (2) is tightly coated on the surface of the base membrane body (1); the base membrane body (1) is prepared from a fabric; and the fabric is a polyester cotton mixed fabric composed of polyester yarn and nylon yarn, wherein the terylen yarn is positioned on the front surface of the fabric, and the nylon yarn is positioned on the back surface of the fabric. The surface of the base membrane is coated with the polypropylene coating; the polypropylene belongs to an organic substance, and sodium chloride and water in seawater are inorganic substances, so the polypropylene is insoluble in the seawater; and therefore, the polypropylene coating can effectively prevent the seawater from contact with ship plates, thereby achieving the salt-resistant effect. The polymeric membrane can implement water absorption and water diversion.

Description

(1) Technical field [0001] The invention relates to a polymer film. (2) Background technology [0002] Our country has a long history of sailing. In the Ming Dynasty, Zheng He led a fleet of seven expeditions to the West. Now the sailing industry is vigorously developed and becoming more and more important. As we all know, seawater contains a lot of salt, which has a certain corrosion effect on marine steel plates. Over time, it will cause safety hazards to the hull, so people think of attaching a film on the steel plate to resist salt. The general polymer film has no The anti-salt function cannot meet the requirements. (3) Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a salt-resistant, water-absorbing and water-conducting polymer film. [0004] The purpose of the present invention is achieved in this way: a salt-resistant water-absorbing and water-conducting polymer film, which includes a base f...
