Embodiment Construction

[0010] 1. Production process:

[0011] 1. Preparation of spraying agent:

[0012] Weigh 2-3kg of polyacrylate emulsion and 1kg of fumed white carbon black respectively, put them in a high-speed stirrer and mix them evenly, and set aside.

[0013] 2. After mixing 30kg polypropylene fiber and 5kg polyester fiber, open, cotton and card according to the conventional production process.

[0014] 3. When laying the net, spray all the spare materials of the above-mentioned polyacrylate emulsion and fumed silica mixed between the net surfaces of adjacent layers.

[0015] 4. Perform acupuncture and hot rolling to form non-woven products, and cut the products into strips to obtain tapes.

[0016] 2. Product testing:

[0017] The main technical indicators are as follows:

Abstract

The invention discloses a production method of a low-smoke halogen-free flame-retardant cable taping, and belongs to the production technical field of cable taping used for lapping of cables. According to the production method, polypropylene fiber and polyester fiber are mixed; a non-woven fabric product is obtained via opening, scutching, carding, lapping, drafting, needle punching, and hot rolling; the non-woven fabric product is subjected to strip cutting so as to obtain the low-smoke halogen-free flame-retardant cable taping. The production method is characterized in that: in the process of lapping, uniformly mixed polyacrylate emulsion and gas phase method white carbon black are sprayed onto mesh sides of adjacent layers. The low-smoke halogen-free flame-retardant cable taping is used for lapping and binding of flame-retardant cable cores; the low-smoke halogen-free flame-retardant cable taping is low in smoke, contains no halogen, glass fiber, or asbestos, and accords with ROHS detection standards; elongation at break is larger than 10%; gram weight is light; thickness is low; oxygen index is larger than 50%; the elongation at break of similar common products is 0%; the low-smoke halogen-free flame-retardant cable taping is relatively soft; fracture is not caused by more than 20 times of folding; upwarping is not caused in cable lapping; the low-smoke halogen-free flame-retardant cable taping can be completely used in lapping; appearance after shielding is rounding; and no wave-shaped product is produced.

Description

technical field [0001] The invention relates to cable production technology, in particular to the technical field of tape production for wrapping. Background technique [0002] Usually the cable wrapping tape is made of glass fiber or asbestos fiber and other non-woven fabrics such as polyvinyl chloride resin. Because it contains flammable components-glass fiber or asbestos fiber, its flame retardancy cannot meet the standard. [0003] In order to achieve the flame retardant function, it is impregnated with a flame retardant after production, and then extruded and heat-set. However, due to the increase of the production process, the cost of such products remains high, and the consumption of flame retardants is large, and it is not environmentally friendly. Contents of the invention [0004] The object of the invention is to propose a low-smoke, halogen-free, flame-retardant taping production process that is beneficial to low-cost production. [0005] Technical scheme of...
