Abstract

The invention relates to a communication optical cable water blocking material for wrapping and filling a communication optical cable and a preparation method of the communication optical cable waterblocking material. The communication optical cable water blocking material is prepared by a water-swellable water blocking coating, a special non-woven fabric, and an aramid yarn, and is characterizedin that the water-swellable water blocking coating is prepared from the following components in percentage by weight: 22 to 42 percent of super absorbent, 1 to 30 percent of adhesive, and 42 to 62 percent of anhydrous alcohol solvent. The water-swellable water blocking coating is coated on the special non-woven fabric in a rolling way or coated on the aramid yarn in a dipping way. The preparationmethod of the communication optical cable water blocking material is characterized by comprising the following steps: 1) preparing the water-swellable water blocking coating; 2) coating the water-swellable water blocking coating on the special non-woven fabric in a rolling way or coating on the aramid yarn in a dipping way to obtain the communication optical cable water blocking material. The communication optical cable water blocking material provided by the invention has the characteristics of no powder removal, strong film coating and extremely low water content, and the preparation methodis simple.

Description

technical field [0001] The invention relates to the field of optoelectronic information technology, in particular to a communication optical cable water-blocking material for wrapping and filling communication optical cables and a preparation method thereof. Background technique [0002] In order to ensure that communication optical cables are waterproof and moisture-proof, manufacturers of communication optical cables need to wrap and fill communication optical cables with water-blocking materials (water-blocking tape and water-blocking yarn). [0003] Researchers at home and abroad have a mindset, that is, use a re-moisture adhesive (water as a solvent) to bond acrylic super absorbent powder to non-woven fabrics and aramid yarns to make water-blocking tapes and water-blocking yarns. [0004] At present, manufacturers who produce communication optical cable water-blocking tapes or water-blocking yarns use re-moisture adhesives to bond water-blocking powder (super water-abso...
