CN1085878C - A kind of production method of cable braided casing - Google Patents

Abstract

The invention discloses a production method of a cable braided sleeve, which comprises the process steps of braiding, rubbing, soaking, spin-drying, rinsing, baking, tube making, ball forming and packaging, wherein SN antistatic liquid is adopted for soaking, the soaking temperature is 38-55 ℃, and the time is 8 hours; the baking temperature is 45-60 ℃, and the baking is carried out until the drying is basically carried out. Compared with the existing polyvinyl chloride glass fiber sleeve, the cable braided sleeve produced by the production method provided by the invention has the advantages of good flexibility, light weight, wide temperature range, high tensile strength and strong electrostatic elimination performance. It is especially suitable for military weapon devices and high-precision instruments, electronic and electromechanical equipment and radio test equipment for space navigation, rocket and aviation.

Description

A kind of production method of cable braided casing

Technical field

The invention relates to a production method of a cable sleeve, in particular to a production method of a cable braided sleeve.

At present, the mechanical protective sleeves used in radios, motors, instruments, various circuit wire bundles, and wiring bundles are made of GB2731 and GB2715 PVC fiberglass sleeves. This product becomes hard and easy to break under low temperature conditions. When the temperature exceeds 32°C, the surface shows sticky and easy-to-stick defects, and its weight is heavy and its flexibility is poor. It is not suitable for military weapons used in aerospace, rockets, and aviation, as well as high-precision instruments, electronic electromechanical equipment, and radio testing equipment. use.

Contents of invention

The purpose of the present invention is to provide a production method of a cable braided sleeve to solve the shortcomings of the prior art.

In order to achieve the above invention, the technical solution adopted in the present invention is: a production method of cable braided sleeve, which is characterized by weaving, kneading, soaking, drying, rinsing, baking, tube making, beating, The packaging process consists of steps, soaking in SN antistatic liquid, soaking temperature is 38°C-55°C, time is 8 hours; baking temperature is 45°C-60°C, bake until basically dry.

The cable braided sleeve produced by the production method provided by the invention has the advantages of good flexibility, light weight, wide adaptable temperature range, high tensile strength and strong static elimination performance. It is especially suitable for use in military weaponry, high-precision instruments, electronic and electromechanical equipment, and radio testing equipment selected by aerospace, rockets, and aviation.
