Embodiment Construction

[0022] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0023] The present invention relates to a composite cable processing method using a flame-retardant new material, comprising the following steps:

[0024] 1) Mix each component into a pre-mixer at 80-120°C and mix evenly, transfer to a high-speed mixer and stir for 10-15 minutes, and finally extrude and granulate to obtain a flame-retardant cable material, which is carried out according to a certain length Cutting to obtain small sections of flame-retardant cable materials; the components include 100 parts of PP; 30-80 parts of PVC; 40-60 parts of LDPE; 10-20 parts of plasticizer; 3-8 parts of antioxidant; 10-15 parts of talcum powder ; 25-45 parts of flame retardant; the stirring speed of the high-speed mixer is 400-800rpm. Extrusion gra...

Abstract

The invention discloses a composite cable processing method using a novel flame-retardant material. The method includes the steps of firstly, preparing components, evenly mixing in a premixing machine, stirring in a high-speed stirrer, and performing extrusion granulation to obtain flame-retardant cable materials; secondly, coating the outer walls of the sectioned flame-retardant cable materials obtained in the first step with adhesives, and stranding the flame-retardant cable materials and filling materials by using silicon core tubes as the center to form stranded bodies; thirdly, arranginga protecting layer outside each stranded body; wrapping each protecting layer with a damping layer, wherein each damping layer section is provided with an amplitude controller and an alarm device matched with the amplitude controller; sixthly, connecting the cable sections with cable connectors. The composite cable processing method has the advantages that produced metal wires are uniform and highin quality, and cables can be effectively prevented from being stolen by the amplitude controllers and the alarm devices.

Description

technical field [0001] The invention relates to a composite cable processing method using a flame-retardant new material, which belongs to the technical field of cable production. Background technique [0002] Cable is a wire product used to transmit electric energy. It is the main carrier of electric power transmission and is widely used in many fields such as lighting, home appliances, and industry. In order to ensure safety, there are particularly strict requirements on the flame retardancy of cables, which is a key research topic in the industry. The production process of flame-retardant cables is mostly manual, so that the thickness of wires and cables produced by this method is different, and the standard cannot be unified, resulting in a low pass rate and a waste of manpower and material resources. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a composite cable processing me...
