Coating process: preparation process of brominated carbon alkyd resin fire retardant coating for cable

The core points are as follows: the components of the fire retardant coating are: bromoalkyd resin, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin, molybdenum trioxide, dimethylsilicone oil, drier, solvent; The preparation steps are as follows: adding the formula solvent, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin and molybdenum trioxides to the multi-purpose dispersion grinder in turn for 30-60min high-speed dispersion, reducing the mixing speed, adding bromoalkyd resin for further dispersion for 20-40mi Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: the components of the fire retardant coating for the cable are: bromoalkyd resin, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin, molybdenum trioxide, dimethylsilicone oil, drier, dissolver; The preparation steps are as follows: adding the formula amount of solvent, ammonium polyphosphate, melamine, pentaerythritol, antimony trioxide, zinc borate, bentonite, titanium dioxide, paraffin chloride, molybdenum trioxide into the multi-purpose dispersion grinder in turn for 30-60min high-speed dispersion, reducing the mixing speed, adding bromoalkyd resin for another 20-40min, adding dimethylsilicone oil, and grinding to The required fineness is then dispersed in a multi-purpose dispersion grinder for 10 to 20 minutes, and then the product is uniformly dispersed by adding a drier Based on the total mass of the brominated carbon alkyd resin cable fire retardant coating, the formulation of the brominated carbon alkyd resin cable fire retardant coating is: brominated carbon 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%, dimethylsilicone oil 0.1%, drier 0.9%, solvent 3 0%; based on the total mass of the prepared brominated alkyd resin, according to the mass percentage, the formulation of brominated alkyd resin is: 60.00% soybean oil acid, 10.00% pentaerythritol, 10.00% phthalic anhydride, 0.02% catalyst, 15.00% brominated epoxy resin and 4.98% xylene; According to the formula of brominated carbon alkyd resin, the preparation steps of brominated carbon alkyd resin are as follows: add soybean oil acid, pentaerythritol and phthalic anhydride in the reaction vessel equipped with mixing device, oil-water separator and thermometer according to the formula amount, protect with nitrogen, start mixing and condensate water, add the catalyst lithium hydroxide and xylene with the formula amount when the temperature is raised to 120 ℃, and keep heating up When the temperature reaches 180 ℃, the heat preservation starts, and the heat preservation process lasts for 50-60min; after the heat preservation stage, add brominated epoxy resin according to the formula amount, so that the temperature is controlled between 180 ℃ ~ 200 ℃, and the reaction time lasts for 90-120min When the acid value is within 10mgkoh / g, the reaction can be stopped, and the temperature is cooled to 180 ℃, the water and xylene in the oil-water separator can be discharged, and the nitrogen gas volume can be opened up, and the brominated carbon alkyd resin can be Xylene is evaporated; the temperature is reduced to 80 ℃, and then the brominated alkyd resin is obtained; the preparation steps of the desiccant for the brominated alkyd resin cable fire retardant coating are as follows: add 5.5G cobalt isooctanoate, 22.2g manganese isooctanoate and 22.2g zirconium isooctanoate in 100g200 × solvent oil, and the desiccant for the brominated alkyd resin cable fire retardant coating can be obtained after high-speed dispersion for 2h at 3500r / min Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
