Problems solved by technology

Most of the raw materials of the rope are chemical fiber raw materials, which have a lower thermal conductivity than metal wires. During the descent, the rope is prone to grinding and heating. A large amount of heat cannot be effectively diffused, which will easily cause the inside of the chemical fiber rope to melt and harden, greatly reducing the performance of the rope. , posing a major safety hazard to rope users
When the rope is bent, etc., the rope is also prone to fatigue loss, resulting in a decline in the function of the rope and a reduction in the service life of the rope

Abstract

The invention discloses a phase-change and energy-storage functional coating adhesive for a chemical fiber rope. The phase-change and energy-storage functional coating adhesive comprises a phase-change and energy-storage material and a waterborne wear-resisting polymer coating adhesive; a waterborne polyurethane dispersion liquid containing a plurality of isocyanate groups is adopted by matrix resin of the water-based wear-resisting polymer coating adhesive; the solid mass accounts for 5%-40% of the mass of the whole dispersion liquid; a phase-change and energy-storage microcapsule is adopted by the phase-change and energy-storage material, and is added to the waterborne wear-resisting polymer coating adhesive; and the mass of the added phase-change and energy-storage microcapsule accounts for 1%-10% of solid mass of the waterborne wear-resisting polymer coating adhesive. Two-way temperature regulation action of the phase-change and energy-storage material is mainly utilized, and the waterborne wear-resisting polymer coating adhesive is combined to arrangement of a coating of a chemical fiber rope, so that the chemical fiber rope has two-way temperature regulation action and wear-resisting effect; the temperature regulation function can be achieved according to the change of an external environmental temperature; and the service life of the rope is greatly prolonged.

Description

technical field [0001] The invention relates to the field of coating finishing of chemical fiber ropes, in particular to a phase-change energy storage functional coating adhesive for chemical fiber ropes. Background technique [0002] As a tool, rope is widely used in fishing, leisure, marine, mining, hoisting and other fields. The rope often bends and rubs during use. In rope use, the safety of the rope is an important indicator of the rope. Take high-rise escape ropes as an example. When a fire or other disaster breaks out in a high-rise building, personnel use emergency escape ropes for emergency evacuation. When in use, the upper end of the rope is fixed and suspended, and the personnel cooperate with the descender to descend. Most of the raw materials of the rope are chemical fiber raw materials, which have a lower thermal conductivity than metal wires. During the descent, the rope is prone to grinding and heating. A large amount of heat cannot be effectively diffuse...
