Problems solved by technology

[0003] At present, the widely used fire retardant coatings for cables are mainly intumescent fire retardant coatings, but due to the addition of a large amount of inorganic flame retardant additives in the coating system and the poor strength and weather resistance of the film-forming polymers, the bending resistance of the coating deteriorates and causes peeling off. At the same time, there are also deficiencies such as migration and precipitation under the action of external factors, and it is often difficult to obtain a fire-resistant coating with comprehensive properties.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a cable fireproof coating. Background technique [0002] Wire and cable are important materials for the power and telecommunications industry. A large number of cable fires at home and abroad, as well as the resulting large-scale power outages or chain disasters caused by this, have led to heavy casualties and huge property losses, making people aware of the importance of cables. The fire hazard is extremely high. It is very necessary to prevent the cable from igniting and prevent the cable from burning. Among them, cable fire retardant coating is a new type of fire retardant coating that integrates decoration and fire protection, developed on the basis of decorative fire retardant coatings. When it is coated on the surface of ordinary cables, it can usually play a certain role in decoration and protection. Once a fire occurs, it can prevent the s...
