Polyester fibre surface coating material for sea mooring rope and production process of polyester fibre surface coating material

Abstract

The invention discloses a polyester fibre surface coating material for a sea mooring rope, which comprises siloxane, stearate and silicon wax. The polyester fibre surface coating material has better smoothness, water repellency and rapid film-forming property, and is uniformly coated on the surface of a Dacron industrial yarn through a high-speed online coating device, a flexible film layer can be rapidly formed on the surface of a Dacron fiber at an intrinsic temperature of 50-80 DEG C of the Dacron yarn; and the film layer has excellent lubrication property and water repellency, thus the Dacron fiber can be endowed with better water repellency and wear resistance so as to improve wet wear resistance of the Dacron industrial fiber. Because silicon wax emulsion is adopted, better corrosion property is endowed to the Dacron fiber, and the sea mooring rope can be immersed in seawater to keep stable working strength, and service life of the mooring rope is prolonged.

Description

technical field [0001] The invention relates to a polyester fiber surface coating material and a production process thereof. Background technique [0002] For a long time, the raw materials of marine cables and marine rigging have been mainly metal materials, but with the continuous professional development of marine cable applications, metal materials have shown many weaknesses. First of all, the metal material has a high specific gravity and its own weight is heavy, which causes a huge load for marine operations. Secondly, metal materials have poor corrosion resistance and are easily corroded and rusted in water, thus greatly shortening their service life. Third, the modulus of metal materials is low, and they are prone to deformation under long-term dynamic loads, which greatly reduces operating safety. In addition, due to the high price of metal materials, the cost of marine operations is also greatly increased. With the continuous development of synthetic fibers, pol...

AI Technical Summary

Problems solved by technology

First of all, metal materials have a high specific gravity and their own weight is heavy, which creates a huge load for marine operations

Secondly, metal materials have poor corrosion resistance and are easily corroded and rusted in water, thus greatly shortening their service life

Third, the modulus of metal materials is low, and they are prone to deformation under long-term dynamic loads, which greatly reduces the safety of operations

The ropes working under this kind of long-term dynamics are constantly rubbing against each other, and the friction is carried out in a wet state, and the friction coefficient is larger, thus accelerating the loss of strength

Due to the combined effect of these two factors, the life of the rigging used in marine operations is short, and the safety and reliability are low.
