Environment-friendly aqueous nanometer fireproof flame-retardant coating and preparation thereof

The invention is environmental-friendly waterborne nanometer fireproof flame-retardant coating and the preparation method, which belong to the fireproof flame-retardant coating manufacturing industry. The flame-retardant coating is obtained through the compounding of two types of flame-retardant agents, waterborne resin, ammonium polyphosphate, melamine, carbon-forming agent, nanometer pigment and filler, micrometer pigment and filler and other auxiliary agent; the flame-retardant coating contains no organic agent and halogen flame retardant, low VOC content, good fireproof property, good physical and chemical properties; the composition of the flame-retardant coating is as follows: the content of waterborne resin is 10-90%; the content of phyllo-silicate nanometer flame retardant which contains phosphor, nitrogen organic intercalation is 1-50%; the content of nanometer magnesium hydroxide flame retardant wrapped by polymer is 1-50%; the content of ammonium polyphosphate is 1-30%; the content of melamine is 1-20%; the content of carbon-forming agent is 1-30%; the content of nanometer pigment and filler is 0.1 to 30%; the content of micrometer filler is 0.1 to 60%; the content of dispersant is 0.1 to 10%; the content of stabilizer is 0.1 to 10%; the content of water is 0.1 to 50%; the content of micrometer pigment is proper; firstly, waterborne resin, nanometer flame retardant, ammonium polyphosphate, melamine, carbon-forming agent, nanometer pigment and fillers, dispersant and stabilizer are put into a planet stirring reactor for stirring and even dispersion; micrometer pigment and filler, water, dispersant and stabilizer are added to the discharged mixture and then put into a high-speed dispersion machine for even dispersion so that the product is obtained.

Preparation and application of floatable magnetic hollow material for removing heavy metal in water and soil

ActiveCN107398251ADevelop resource utilizationEfficient adsorption capacity of heavy metalsOther chemical processesWater contaminantsResource utilizationHusk
The invention discloses preparation and application of a floatable magnetic hollow material for removing heavy metal in water and soil. Agricultural wastes of musaceae, such as banana, dried-up leaves, corn dried-up leaves and rice husks are combined with alginate to prepare the floatable magnetic hollow material containing nanometer ferroferric oxide and nanometer ferrous chloride, and the floatable magnetic hollow material is applied to remove the heavy metal in the water and the soil, so that not only is the resource utilization of the agricultural wastes developed, and a new way is opened for farmer income increase, but also the prepared nanometer ferrous chloride and nanometer ferroferric oxide and a high-quality porous biological carbon material have a high-efficient heavy metal adsorption capability, the hollow material with magnetism and floated on a water surface can be conveniently recovered, and the heavy metal in the water and the soil is removed. The floatable magnetic hollow material provided by the invention is wide in application range, can be used for renovating the water with heavy metal pollution such as urban or industrial sewage, rivers, pools and lakes, and can be also used for renovating the soil with heavy metal pollution such as rice fields, water vegetable fields and green plant fields.
