Abstract
The present invention discloses an optical fiber cable sheath composite material and a preparation method thereof, an optical fiber cable sheath and an optical fiber cable. The optical fiber cable sheath composite material is characterized by comprising, by weight, 90-98% of polyethylene, 1-10% of glass beads, and 0.1-8% of an additive. According to the present invention, the glass beads are used so as to reduce the raw material cost of the composite material by 4%, and the glass beads can effectively improve the flowability of the polyethylene material, particularly the flowability of the recovered polyethylene material, and can flexibly adjust the density of the composite material according to different used materials so as to meet the specific requirements of the optical fiber cable sheath material manufacturing and the optical fiber cable manufacturing.
Description
technical field [0001] The invention relates to a composite material for an optical cable sheath, a preparation method thereof, an optical cable sheath and an optical cable. Background technique [0002] In order to protect the optical cable, an optical cable sheath must be provided outside the cable core. With the widespread popularization of optical cables, the demand for optical cable sheath materials is increasing day by day. However, due to the specific requirements of the manufacturing process and the use environment of the optical cable sheath, the cost of polyethylene materials in the traditional optical cable sheath is relatively high, resulting in a high overall cost of the optical cable. Therefore, there is a great need for a composite material that is relatively low in cost and can meet the specific requirements of the manufacturing process of the cable sheath and the environment in which the cable sheath is used, thereby reducing the cost of the cable sheath an...
