Problems solved by technology

The disadvantage is that the fiber itself has no water absorption performance. It is through the water-absorbing resin powder in the interlayer of two layers of semi-conductive cloth, which expands and absorbs water when it encounters water. There is a lot of dust, which is harmful for workers to breathe, and the production process is complicated and the cost is high

Abstract

The invention relates to a super-strong nano semi-conductive buffer water-blocking tape and a processing process thereof. The processing process comprises the following steps: (1) a piece of acupuncture cotton non-woven fabric is produced with SAF fiber through a acupuncture cotton production process; and (2) the acupuncture cotton non-woven fabric is immersed in oily nano conductive liquid, extruded and dried in vacuum, wherein the oily nano conductive liquid contains 15-20% of nano hollow carbon tubes, 25-30% of oily acrylic acid gel, and 40-55% of ethyl ester. The processing process is simple, and a superior super-absorbent semi-conductive buffer material is produced by using a conventional acupuncture cotton non-woven fabric production process, selecting a special super-absorbent material, using a new nano silica gel anti-sticking technology and using a new energy-saving and efficient vacuum drying process.

Description

technical field [0001] The invention relates to a super-strength nano-semiconductive buffer water-blocking tape and its processing technology, which is mainly used in the inner wrapping of ultra-high voltage cables of 110KV, 220KV and above 500KV for the functions of eliminating static electricity, electric sparks, water blocking and buffering. Background technique [0002] At present, the high-performance nano-semiconductive cushioning and water-blocking materials on the market use non-absorbent polyester fibers to produce needle-punched cotton through the conventional production process of needle-punched cotton non-woven fabrics, and then soak them in water-based semi-conductive liquids. , Dried into semi-conductive buffer cotton, then coated with adhesive on the surface, sprayed with water-absorbent resin powder, and then compounded with another layer of semi-conductive non-woven fabric. The disadvantage is that the fiber itself has no water absorption performance. It abs...
