Problems solved by technology

However, the existing aluminum-plastic composite pipe has a five-layer structure, and the outer layer of plastic and the aluminum layer are bonded by hot melt adhesive, which is not conducive to peeling off during use.
The outer plastic of the existing aluminum-plastic composite pipe must be pipe-grade polyethylene with high melt strength. If there is no hot-melt adhesive between the outer plastic and the aluminum layer during the alternating process of cold and heat, the easy-to-leave layer will fall off
In addition, the existing aluminum-plastic composite pipe has low hardness and tensile strength, and its rigidity is far below the requirements of the sheath pipe for automotive cables.

Abstract

The invention relates to an aluminium-plastic composite tube for a cable. The tube comprises a first plastic layer, a bonding layer, an aluminium alloy layer, and a second plastic layer successively from inside to outside. The elongation rate of the aluminium alloy layer is larger than 10%, the tensile strength is larger than 150MPa, and the rigidity is 40 to 50HV. According to the invention, the aluminium-plastic composite tube can be used as a cable casing tube of an automobile, thereby reducing the weight of the automobile body; a certain shielding effect on the electromagnetic interference can be realized; the corrosion-resistant and anti-rust performances are excellent; and the service life is long. Because no bonding layer is arranged between the aluminium alloy layer and the second plastic layer, the second plastic layer at the surface of the mounting port can be stripped easily, so that installation becomes convenient.

Description

technical field [0001] The invention belongs to the field of automobile cable protection, and in particular relates to an aluminum-plastic composite pipe for cables. Background technique [0002] Body lightweight is an important research aspect of new energy vehicles. Under the premise of ensuring the strength and safety performance of the car, reducing the curb weight of the car as much as possible can improve the power of the car, reduce fuel consumption, and reduce exhaust pollution. This means that new energy vehicles should maximize the use of lightweight materials, such as aluminum and plastics. The main cable bushing is an indispensable part of the car, which prevents short-circuit accidents caused by disconnection of the power line, protects the car cables from being damaged, and also plays a certain role in shielding the electromagnetic field interference. Most traditional fuel vehicles use metal casings. Although they have a good protection effect on cables, stron...
