example 1
[0027] A heat-resistant and heat-insulating composite cable sleeve, comprising a first glass fiber sleeve 1, a heat-insulating flame-retardant coating 2, a second glass fiber sleeve 3 and a flame-retardant and wear-resistant coating 4, the first glass fiber sleeve 1. A rubber layer is provided on the outer surface and formed into one body. 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;
[0047] When the temperature is 100-120°C, add 100Kg of the above-mentio...
example 3
[0050] Fabricate the casing according to the first to fifth steps in Example 1. In the third step, the coating thickness is 4mm. When the outer temperature of the casing is 600°C, the inner temperature of the casing can be reduced to 200°C.
[0051] The preparation of heat-insulating and flame-retardant coatings is as follows:
[0052] Prepare polyester pulp by weight ratio: 20.0% ammonium polyphosphate, 45.5% polyester resin, 8.2% ammonium borate, 9.8% zinc oxide, 8.5% starch and 8.0% 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.
[0053] The adduct is generated by a mixed solvent of cyclohexanone and xylene according to a volume ratio of 1:3;
[0054] The catalyst is produced by dibutyltin dilaurate and xylene in a volume ratio of 1:9;
[0055] When the temperature is 100-120°C, add 100Kg of the above-mentioned polyester pulp into 20Kg of adduct...
