Embodiment Construction

[0033] use Figure 1-Figure 7 An oil-resistant, flame-retardant, radiation-crosslinked thermoplastic polyester elastomer cable according to one embodiment of the present invention will be described below.

[0034] Such as Figure 1-Figure 7 As shown, a waterproof halogen-free flame-retardant cable according to the present invention, in parts by mass, the raw material components of the cable outer cladding include: 20 parts of ABS resin, 20 parts of polyolefin, 22 parts of carbon powder, granite 10 parts of powder, 1 part of wood fiber powder, 10 parts of nitrile rubber, 10 parts of compatibilizer, 30 parts of expandable graphite powder, 1 part of high temperature additive, 0.5 part of flow modifier, 1 part of antioxidant, 0.7 part of talc powder part; the carbon powder is ground by a ball mill and sieved by a 400-mesh sieve to obtain carbon powder; the wood fiber powder is cut by an electric saw to produce sawdust, and the sawdust is recycled and ground into powder. It is ob...

Abstract

The invention belongs to the technical field of cables, and particularly relates to a waterproof halogen-free flame retardant cable. The cable comprises a cable main body, a clamping ring, a cable joint and a connecting ring, wherein the front end of the cable main body is fixedly connected with the clamping ring; the front end of the clamping ring is fixedly connected with the cable joint; the cable joint can be mutually clamped with the connecting ring, and clamping holes are formed in the upper end wall and the lower end wall of the cable joint; the right ends of the clamping holes are circular, and the left ends of the clamping holes are parallelogram-shaped. the combustibility of adopted carbon powder and granite powder is almost zero, so that the flame-retardant effect is relativelystrong, and the flame-retardant effect of a cable outer cladding can be greatly improved by matching the carbon powder and granite powder with expandable graphite powder; through the lubricating characteristics of the expandable graphite powder and talcum powder, the mixing and stirring efficiency of all the components can be improved in the process of manufacturing the cable outer cladding; the hardness of the granite is higher than that of other raw materials, and then the structural strength of the cable outer cladding can be improved by neutralizing the granite with other raw materials.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a waterproof, halogen-free and flame-retardant cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal energization and external insulation. It is mainly used for multiple functions such as control installation, connection equipment, and power transmission. It is a common and indispensable thing in daily life. Since the cable is electrified, it needs to be installed with special care. For the safety of the cable, the cable is usually laid in the underground soil layer at this stage to ensure that it will not be damaged and excavated by humans. Creeping, at this time, will cause twisting force to the cables laid underground, resulting...
