Abstract

The invention discloses a fireproof filling insulating layer formula for a special cable. The fireproof filling insulating layer is prepared from, by weight, 20-25 parts of sandy soil, 9-22 parts of cordierite powder, 30-36 parts of mullite powder, 8-20 parts of asbestos powder, 10-30 parts of calcium carbonate, 25-36 parts of perlite, 20.6-30 parts of polyacid ammonium, 20-26 parts of pentaerythritol, 15-30 parts of antimonous oxide micro-crosslinked resin, 40-50 parts of a flame retardant, 16-18 parts of a flame-retardant synergist, 17-21 parts of an antioxidant, 16-30 parts of a lubricant, 9.6-16.8 parts of chlorinated rubber, 22-36 parts of dioctyl phthalate, 60-66 parts of an antioxidant, 40-60 parts of teflon, 12.6-13.8 parts of an absorbent uv-531, 2.8-3.6 parts of toner, 16-18 parts of wintergreen oil and 10-20 parts of silicone oil. The technological process is simple, the raw material ratio is reasonable, and the reasonable filling raw material is provided for cable sheath production; the raw material has good heat insulating performance and fireproofing performance, so that normal use of the cable is guaranteed, the service life of the cable is prolonged, the use effect is good, and the quality of the cable product is guaranteed.

Description

technical field [0001] The invention relates to a special cable fireproof filling insulating layer formula. Background technique [0002] Cables are widely used in control installation, equipment connection, and power transmission, and are an indispensable and important transmission medium in industry and civil use. Cables have various specifications and models to meet the needs of different equipment and transmission purposes. Cables can short or open during use, causing power and information transmission to fail. In the event of a fire, the cable needs to have a certain fire protection function, so as to ensure that the data can be effectively saved before the line is paralyzed, reduce the risk of data loss, and ensure that the cable can ensure the safety of electrical equipment and lines during the power transmission process. run. However, the existing cables have unsatisfactory fire performance. When a fire occurs, the risk of data loss is high, and the transmission e...
