Problems solved by technology

[0003] At present, solvent-based cable fire retardant coatings are widely used, and intumescent fire retardant coatings are the main ones. However, due to the addition of a large amount of inorganic flame retardant additives in the coating system, the coating has poor bending resistance and causes peeling off. At the same time, there are external Migration, precipitation and other deficiencies under the action of factors

preparation example Construction

[0033] The preparation steps of bromocarbon alkyd resin are:

[0034] In a 500ml four-neck flask equipped with a stirring device, an oil-water separator and a thermometer, add soyoleic acid, pentaerythritol, and phthalic anhydride in sequence according to the formula, protect with nitrogen, start stirring and condense water, and add the formula when the temperature rises to 120°C amount of catalyst lithium hydroxide and xylene, and continue to heat up to 180°C, start heat preservation, the heat preservation process is 50~60min; after the heat preservation stage is over, add brominated epoxy resin according to the formula, so that the temperature is controlled at 180°C~200 ℃, the reaction time is 90 minutes to 120 minutes, when the acid value is within 10mgKOH / g, the reaction can be stopped, the temperature is lowered to 180 ℃, the water and xylene in the oil-water separator are released, and the amount of nitrogen is increased to release the bromine The xylene in the carbon al...

Abstract

The invention relates to a bromine carbon alkyd resin cable fireproof paint and its preparation method. The fireproof paint comprises the following components of: bromine carbon alkyd resin, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin, molybdenum sesquioxide, dimethyl silicon oil, a drier, and a solvent. The preparation method consists of the steps of: adding the formula required amounts of the solvent, the ammonium polyphosphate, the melamine, the pentaerythritol, the antimony trioxide, the zinc borate, the bentonite, the titanium dioxide, the chlorinated paraffin, and the molybdenum sesquioxide into a multi-purpose dispersion mill in order, conducting high speed dispersion for 30-60min, reducing the stirring speed, adding the bromine carbon alkyd resin to carry out further dispersion for 20-40min, adding the dimethyl silicon oil, using a cone mill to mill the mixture to a desired degree of fineness, then performing dispersion in the multi-purpose dispersion mill for 10-20min, and adding the drier which is then dispersed uniformly, thus obtaining the product.

Description

technical field [0001] The invention relates to polymer chemistry and polymer coating composition technology. Background technique [0002] Under the premise of the continuous development of my country's electric power industry, the application of large-load, ultra-high-voltage transmission and power supply technology is becoming more and more common, and the fire risk of wires and cables is also increasing. In terms of flame retardant and fire protection of wires and cables, in addition to flame retardant treatment of wire and cable insulation and sheath layers, coating fire retardant coatings can play an effective fire barrier for some fixedly laid wires and cables. combustion effect. [0003] At present, solvent-based cable fire retardant coatings are widely used, and intumescent fire retardant coatings are the main ones. However, due to the addition of a large amount of inorganic flame retardant additives in the coating system, the coating has poor bending resistance and...
