Abstract
The invention discloses a low permanent deformation reel cable sheath material. The material comprises CPE, CR, EVA, carbon black, talcum powder, calcium carbonate, silicon dioxide, antimony trioxide, magnesium oxide, DOA, an anti-aging agent RD, TAIC and DCP. The CPE, the CR and the EVA are used together, so that the permanent deformation rate of the sheath material is increased, and the material formula cost is reduced; the talcum powder and the calcium carbonate are used together, the talcum powder can improve the tensile strength of the material, the calcium carbonate can improve the crosslinking degree of the material, and due to the fact that the unit prices of the two fillers are low, the material cost can be greatly reduced; the carbon black obviously enhances the tensile strength of the material, and the silicon dioxide obviously enhances the tear strength of the material.
Description
technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a reel cable sheath material with low permanent deformation. Background technique [0002] In order to improve the service life of the reel cable sheath, the material of the reel cable sheath needs to have good properties such as high strength and low permanent deformation rate. In the traditional technology, the reel cable sheath material is made of neoprene, but because neoprene is expensive, and the neoprene is easily cross-linked in advance after adding a vulcanizing agent, it cannot be conveniently used for cable extrusion in the future, and the production efficiency is low. extremely low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a low permanent deformation reel cable sheath material. [0004] The technical solution adopted by the present inve...
