Abstract

The invention discloses a wear-resistant and weather-resistant rope coating. The coating is prepared from the following components in parts by mass: 15-30% of waterborne polyurethane resin, 1-5% of polytetrafluoroethylene, 1-3% of a hydroxyphenyl benzotriazole-based ultraviolet absorber, 1-5% of sodium methylene dinaphthalenesulfonate, 0.1-2% of a sorbitan ester emulsifier, 0.02-1% of an organotin drying catalyst, 0.01-1% of an aminopropyl silane coupling agent and 53-82% of water. The coating has reasonable process formula; by using polytetrafluoroethylene as a wear-resistant agent, polytetrafluoroethylene is added into the rope, the wear-resistant property of the rope is maintained for a long time; by adopting the hydroxyphenyl benzotriazole-based compound as the ultraviolet absorber, the strong sunlight resistance and weather resistance of the rope are effectively ensured, and thus the service life of the rope is greatly prolonged; and by adopting waterborne polyurethane resin as a matrix, waterborne polyurethane resin is added so as to ensure that the rope, the wear-resistant agent and the ultraviolet absorber are combined for a long term and meanwhile, the waterborne polyurethane resin has the wear-resistant, corrosion-resistant and anti-ultraviolet functions.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a wear-resistant and weather-resistant rope coating. Background technique [0002] With the development of society and economy, the design of economic buildings is becoming more and more diversified, and the application fields of cables are becoming more and more extensive, which has stricter requirements on the quality and durability of cables. With the development of water-based polyurethane resin, water-based polyurethane coatings have been widely used in various fields, such as the textile and garment industry, for various functional coatings, and the effect is very remarkable. [0003] In recent years, as customers have higher and higher requirements for ropes, not only the strength and toughness of the ropes are required, but also the wear resistance of the ropes must be ensured, and their performance can be maintained for a long time in sunlight and air. Rope coating has...
