Abstract

The invention belongs to the field of a functional polymer material, and especially relates to super absorbent resin and a preparation method and an application thereof. The non-ionic polymer-polyvinyl alcohol is taken as a water-absorption main body, physical water retention of cassava starch and chemisorption capability of polyvinyl alcohol form complementation, at the same time, lignosulfonic acid is introduced for enhancing the anti-shearing capability, hydroxypropyl methyl cellulose enhances vertical stretching capability, the super absorbent resin is prepared by multiple steps, has high water absorption under high pressure and high salinity, and can fully absorb the liquid to reach water blocking effect. The raw materials have the advantages of nontoxicity and innocuousness, wide acquisition approach, environmental protection, and low preparation energy consumption, and are suitable for industrial production. The super absorbent resin has excellent mechanical property, high pressure resistance, and salt resistance, is suitable for various complex environment, and can be used as an optical cable water-blocking material.

Description

technical field

[0001] The invention belongs to the field of functional polymer materials, and in particular relates to a superabsorbent resin and its preparation method and application. Background technique

[0002] With the rapid development of global informatization and the continuous advancement of communication technology, single-mode optical fiber cables with good signal transmission performance have been widely used; as the area where optical cables are laid is becoming wider and wider, the environment for optical cable construction is becoming more and more complex. The higher; in order to maintain the fidelity of communication data and the long service life of the line, it is particularly important to maintain the humidity balance inside the optical cable.

[0003] The traditional water-blocking material is fiber paste and cable paste, which is a non-polar ointment with polyolefin as the base oil; due to the high requirement of filling degree and the phenomenon of w...
