A low-smoke flame-retardant optical cable ointment

Abstract

The invention discloses low-smoke-amount flame-retardant optical cable factice. The factice comprises, by mass, 78-85 parts of base oil, 9-12 parts of composite thickener, 0.8-1.5 parts of flame retardant and 0.5-0.8 part of antioxidant. The base oil is hydrogenated paraffin base oil and hydrogenated naphthene base oil mixed oil, and the mass ratio of hydrogenated paraffin base oil to hydrogenatednaphthene base oil is (2-2.5):(3-4.2); the composite thickener comprises polyacrylamide and fatty alcohol-polyoxyethylene ether, and the mass ratio of polyacrylamide to fatty alcohol-polyoxyethyleneether is (5-6):(7-8); the flame retardant comprises triallyl isocyanurate and nano tin powder, and the mass ratio of triallyl isocyanurate to the nano tin powder is (90-100):(0.15-0.2). The factice solves the technical problems that optical fibers are easy to combust and release a large amount of toxic smoke and toxic gas in combustion. The low-smoke-amount flame-retardant optical cable factice isprovided, the high-molecular reaction type flame retardant is added, the factice does not contain halogen-free flame retardant, the smoke amount is low, and the performance of the factice is not influenced.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to a low-smoke flame-retardant optical cable ointment. Background technique [0002] During the long-term use of the optical cable, due to the erosion of moisture and water, the transmission performance will be reduced, which will affect its normal use. In the production of optical cables, there are two main types of water-blocking materials for cable cores: one is water-blocking filling ointment, and the other is water-blocking tape and water-blocking yarn. Because the optical cable water-blocking filling ointment can play a good waterproof, moisture-proof, cushioning and bonding role in production, has good reliability and is easy to maintain, it is widely used in optical cable production. Optical cable filling ointment is divided into fiber ointment and cable ointment in terms of practical functions. Optical cable filling ointment is one of the important material...
