Preparation of Fire-retardant coating of bromocarbon alkyd resin cable

The components of bromocarbon alkyd resin cable fireproof coating are: bromocarbon alkyd resin, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin, molybdenum trioxide, di Methyl silicone oil, drier, solvent;

The preparation steps are as follows: add the formula solvent, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin, and molybdenum trioxide into a multi-purpose dispersing Grinder in sequence for high-speed dispersion for 30 ~60min, reduce the stirring speed, add bromocarbon alkyd resin and disperse for 20~40min, add dimethyl silicone oil, grind to the required fineness with a conical mill, then disperse in a multi-purpose dispersing Grinder for 10~20min, then add catalyst The dry agent is dispersed evenly to obtain the product.

Based on the total mass of bromocarbon alkyd resin cable fire retardant coating, calculated by mass percentage, bromocarbon alkyd resin cable fire retardant coating formula is: bromocarbon alkyd resin 30%, ammonium polyphosphate 12%, melamine 5%, pentaerythritol 4% , antimony trioxide 4%, zinc borate 3%, bentonite 3%, titanium dioxide 4%, chlorinated paraffin 3%, molybdenum trioxide 1%, simethicone 0.1%, drier 0.9%, solvent 30 %;

Based on the total mass of the bromocarbon alkyd resin prepared, in terms of mass percentage, the bromocarbon alkyd resin formula is: 60.00% soybean oil, 10.00% pentaerythritol, 10.00% phthalic anhydride, 0.02% catalyst, brominated epoxy resin 15.00%, xylene 4.98%;

According to the bromocarbon alkyd resin formula ingredients, the preparation steps of the bromocarbon alkyd resin are: add soy oil, pentaerythritol, and phthalic anhydride in sequence according to the formula amount in a reaction vessel equipped with a stirring device, an oil-water separator and a thermometer, Nitrogen protection, start stirring and condensing water, add the formula catalyst lithium hydroxide and xylene when the temperature rises to 120°C, 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, according to the formula Add brominated epoxy resin in an appropriate amount, so that the temperature is controlled between 180°C and 200°C, and the reaction time is 90 minutes to 120 minutes. When the acid value is within 10mgKOH/g, the reaction can be stopped, and the temperature is lowered to 180°C to release oil and water. For the water and xylene in the separator, increase the amount of nitrogen to distill out the xylene in the bromocarbon alkyd resin; cool down to 80°C, and get the bromocarbon alkyd resin; the bromocarbon alkyd resin cable fireproof coating The preparation steps of the drier are: in 100g of 200# solvent oil, add 5.5g of cobalt isooctanoate, 22.2g of manganese isooctanoate, 22.2g of zirconium isooctanoate, and disperse at a high speed of 3500r/min for 2 hours to obtain bromocarbon alkyd acid Drier for resin cable fireproof coating.
