Abstract

The invention relates to a flame-retardant fireproof coating material for a cable and a preparation method thereof. The material comprises the following components in parts by mass: 100 parts of an emulsion base material, 95-130 parts of a dehydrating agent, 35-40 parts of an expanding agent, 30-38 parts of a charring agent, 15-30 parts of expansible graphite, 5-10 parts of a metal oxide, 5-10 parts of ethylene bis stearamide, 5-10 parts of silicon dioxide and 80-130 parts of deionized water. The coating material prepared by the invention has a very high flame retardant efficiency. EBS adopted by the invention can effectively improve the dispersibility of a powder material, so that agglomeration is avoided; meanwhile, caking can be also prevented, and the water resistance and the dried surface smoothness of the coating material are improved. A test of a combustion property verifies that the flame-retardant fireproof coating material provided by the invention is superior to an existing product in performances of combustion time, heat release and smoke release.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a flame retardant coating material for cables and a preparation method thereof. Background technique [0002] In recent years, with the rapid growth of cable consumption, the incidence of cable fire accidents has also shown an obvious increasing trend. Relevant statistics show that more than 60% of the fires in cities are caused by the burning and spreading of cables caused by electrical equipment failure or overloading of cables. Therefore, it is particularly important to carry out fire-resistant and flame-retardant treatment on cables, and brushing with flame-retardant and refractory coating materials is one of the commonly used methods. [0003] The cable fireproof coating itself is flammable or non-combustible, and can decompose non-combustible gas or form a fireproof and heat-insulating protective layer in case of fire, thereby preventing the thermal decom...
