Abstract

The invention discloses a self-rolling type low-temperature protective sleeve for aviation, which is prepared by the following steps: S1, mixing protective sleeve materials to obtain a mixture, putting the mixture into a kneading machine, controlling the air pressure to be 0.23 MPa, and kneading and banburying for 10-15 minutes; S2, heating the mixture subjected to internal mixing to 110120 DEG C,and carrying out plastication for 22 hours; S3, adding the plastified mixture into an open mill, mixing for 10-15 minutes at the temperature of 110-120 DEG C, and then carrying out roller wrapping atthe temperature of 40-50 DEG C; S4, adding the mixed mixture into mixing and stirring equipment, uniformly mixing and stirring the mixture, granulating the same, extruding the same and granulating the same to obtain the self-rolling type low-temperature protective sleeve for aviation. The protective sleeve is made of one or a mixture of more of polyethylene, polyvinyl chloride, polypropylene andnylon in any proportion.

Description

technical field [0001] The invention relates to the technical field of low-temperature protection for cables, in particular to a self-rolling low-temperature protection sheath for aviation. Background technique [0002] In the field of aerospace and electronic equipment, various cables and cable protective sleeves are often used. However, some cables will be directly exposed to low temperature environments for a long time, and are vulnerable to various natural environments and man-made damage. The service life is reduced, and the service life and safety of the cable are significantly affected, which affects the power consumption of aerospace and electronic equipment. [0003] The existing cable protective sheath cannot resist the low temperature environment. In the process of manufacturing the cable protective sheath, mixing and stirring equipment is often used. The existing mixing and stirring equipment has the problem of insufficient stirring, which leads to poor overall q...
