A heat-insulating and flame-retardant coating 3 is provided between the first glass fiber sleeve 1 and the second glass fiber sleeve 3. A flame-resistant and resistant coating is provided on the outer surface of the second glass fiber sleeve. Grinding coating4.

[0028] A method for manufacturing a high-temperature-resistant heat-insulating composite cable sleeve:

[0029] The first step: the first glass fiber sleeve 1 and the second glass fiber sleeve 3 are formed by twisting and ply weaving with alkali-free glass fiber yarn;

[0030] Step 2: Take the first fiberglass casing 1 as the substrate, and inflate the first fiberglass casing 1 wit...

example 2

[0042] Fabricate the casing according to the manufacturing method of the first to fifth steps in Example 1, wherein the coating thickness in the third step is 2mm, when the outer temperature of the casing is 350°C, the inner temperature of the casing can be reduced to 300°C.

[0043] The preparation of heat-insulating and flame-retardant coatings is as follows:

[0044] Prepare polyester pulp by weight ratio: 10.5% ammonium polyphosphate, 60.0% polyester resin, 17.8% ammonium borate, 4.7% zinc oxide, 2.5% starch and 4.5% antimony trioxide, followed by Put it into a container, stir evenly, and grind it with a grinder until the fineness of the above-mentioned mixed material reaches 80-100 microns.

[0045] The adduct is generated by a mixed solvent of cyclohexanone and xylene according to a volume ratio of 1:3;

[0046] The catalyst is produced by dibutyltin dilaurate and xylene in a volume ratio of 1:9;

Abstract

The invention discloses a high-temperature-resistant heat insulation composite cable sleeve and a manufacturing method thereof. The composite cable sleeve comprises a first glass fiber sleeve body, a second glass fiber sleeve body, a heat insulation flame-retardant coating and a flame-retardant wear-resistant coating, wherein the outer surface of the first glass fiber sleeve body is evenly dip-coated with a rubber layer firstly and then evenly dip-coated with the heat insulation flame-retardant coating after being vulcanized in a vertical electric dry oven, and then the first glass fiber sleeve body is dried for 45 min- 60 min at a contact temperature of 120+/-10 DEG C; the first glass fiber sleeve body provided with the rubber layer and the heat insulation flame-retardant coating is sleeved with the second glass fiber sleeve body, and the outer surface of the second glass fiber sleeve body is evenly dip-coated with the flame-retardant wear-resistant coating. The cable sleeve has the advantages of being resistant to inflaming, resistant to high temperature and resistant to wearing, and normal working of internal cables is guaranteed.

Description

technical field [0001] The invention relates to a cable casing, in particular to a high-temperature-resistant and heat-insulating composite cable casing and a manufacturing method thereof. Background technique [0002] The application of cables is extremely wide. Generally, ordinary cables can be used in daily life. However, for aerospace vehicles and other high-speed and high-temperature environments, direct use of ordinary cables cannot meet their high temperature resistance and heat insulation requirements, and they are pulled in a small space. When laying, it is easy to cause damage, and the use of high temperature resistant cables has its own limitations, high cost, poor flexibility, and is not convenient for cable laying in complex environments. Usually, ordinary cables are inserted into the casing. The Chinese patent "A Flame Retardant Cable sleeve", application number: 201020595977.X, discloses a flame-retardant cable sleeve, which is characterized in that a flame-re...
