Problems solved by technology

[0003] However, aramid fiber is the worst heat-resistant organic fiber. Under the extreme conditions of open flame or high temperature (such as 300°C), the mechanical properties of aramid fiber rope deteriorate rapidly. When the temperature reaches 280°C, its mass loss reaches 41%; 300°C Under the condition of ℃, the breaking strength remains 80.3% after 5 hours, 61.0% after 10 hours, and only 15.0% after 20 hours

Embodiment 1

[0034] The preparation method of the fire-proof and heat-insulating high-performance aramid rope of this embodiment includes the following steps:

[0035] 1. Wash the braided 12-strand aramid rope with water and dry it, then add it to a phosphoric acid solution with a mass fraction of 20%, soak it for 30 minutes at 20°C, take it out and wash it with distilled water until neutral.

[0036] The preparation method of the pretreatment solution is as follows: directly add the acid to the water and stir well.

[0037] 2. Soak the rope in the functional coating for 30 minutes, take it out for low-temperature cross-linking and curing, bake at 50°C, and bake for 5 hours to prepare a fireproof and heat-insulating high-performance aramid rope. The functional coating comprises the following components:

Abstract

The invention provides a fireproof heat-insulating high-performance aramid fiber rope. A preparation method comprises the following steps: 1) after immersing an aramid fiber rope through a pre-treatment liquid, cleaning and drying the aramid fiber rope; and 2) then immersing the aramid fiber rope in a prepared functional coating to form a functional coating and regulating the thickness of the functional coating by adjusting the immersing time; and after immersion for a period of time, performing low-temperature roasting and crosslinking to prepare the finished product. The fireproof heat-insulating high-performance aramid fiber rope is prepared by means of a coating technology, and as the raw materials of the flame-retardant coating have the advantages of being environment-friendly, low in smoke and low in toxicity and the flame-retardant coating does not affect the mechanical properties of the rope material, when the rope comes across a fire to burn, the coating is heated first to form char and isolate heat and oxygen, so that a role of protecting inner rope is played. The fireproof heat-insulating high-performance aramid fiber rope is prepared by means of the coating technology, so that the coating still can obtain a very good fireproof and heat-insulating effect even under the circumstance of small thickness of the coating.

Description

technical field [0001] The invention relates to a fireproof and heat-insulating high-performance aramid fiber cable, which belongs to the technical field of flame-retardant ropes. Background technique [0002] Aramid fiber has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, insulation, anti-aging, long life cycle, etc. It is widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment and other fields. Aramid fiber has extremely high strength, and its weight ratio tensile strength is 6 times that of steel wire, 3 times that of glass fiber, and 2 times that of high-strength nylon industrial yarn; its tensile modulus is 3 times that of steel wire, and 2 times that of glass fiber , 10 times that of high-strength nylon industrial yarn; the continuous use temperature range of aramid fiber is extremely wide, and it can operate n...
