Problems solved by technology

[0003] Commonly used are organic intumescent fire retardant coatings, organic intumescent fire retardant coatings are mostly based on modified amino or perchlorethylene resin and chlorinated rubber, and are composed of various fire retardants, plasticizers, solvents, etc. Solvent-like coatings have many problems such as solvent toxicity, price, transportation safety, construction safety and environmental pollution; in addition, the application effect of oil resistance is not ideal
Water-based cable fire retardant coatings also appear on the market, and most of them are composed of water-based emulsions with a large amount of plasticizer and a variety of fire retardants. Appearance of yellowing and loss of softness

Abstract

The invention discloses a fireproof coating for a waterborne cable, belonging to the technical field of chemical industry. The fireproof coating is composed of the following components in parts by weight: 15-18 parts of acrylic resin, 10-15 parts of phenol formaldehyde resin, 20-26 parts of ammonium polyphosphate, 12-15 parts of pentaerythritol, 5-8 parts of tripolycyanamide, 5-9 parts of zinc borate, 3-7 parts of chlorinated paraffin, 0.1-0.5 part of flatting agent, 0.8-1.2 parts of defoaming agent, 2-3 parts of organic bentonite, 1-5 parts of inorganic pigment and 15-25 parts of water. The coating disclosed by the invention is good in fire resistance and heat insulation property, strong in binding power, high in strength, good in water resistance as well as acid and alkaline corrosion resistance, good in decoration and reduced in cost.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a coating, in particular to a water-based cable fireproof coating. Background technique [0002] At present, the power and telecommunications industry has become an important pillar of the national economy, and wires and cables are important materials for the power and telecommunications industry. However, the occurrence of a large number of cable fires at home and abroad, and the resulting large-scale power outages or chain disasters have resulted in major casualties and huge property losses, making people realize that cable fires are extremely harmful and prevent If the cable is on fire, it is very necessary to prevent the cable from spreading. 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 t...
