Embodiment Construction

[0018] During specific implementation, combined with figure 1 Processing flow chart.

[0019] A processing technology of magnesium hydroxide flame retardant, comprising the following steps:

[0020] 1) Feeding: Select 325-mesh brucite powder and add it to the feeding bin.

[0021] 2) Wet grinding: raw materials are automatically added from the feeding bin to the wet mixing mill for grinding. Due to the different uses of the products, the product fineness is 2000 mesh, 3500 mesh, 6000 mesh, etc. According to the different requirements of product fineness, the product adopts secondary grinding process. When the fineness is less than 3000 mesh, the primary grinding process is adopted; when the product fineness is required to be above 3000 mesh, the brucite slurry is ground by the secondary grinding process and pumped into the storage tank.

[0022] 3) Pressure filtration: The brucite slurry stored in the storage tank is pumped into two filter presses for graded pressure filtr...

Abstract

The invention discloses a magnesium hydroxide flame retardant agent processing process, and relates to the technical field of magnesium hydroxide flame retardant agent processing, wherein material feeding, two-stage wet grinding, two-stage pressure filtration, drying, modification and packaging are performed to prepare the magnesium hydroxide flame retardant agent finished product having the required particle size. According to the present invention, the operation of the processing process is simple; the magnesium hydroxide flame retardant agent produced through the process has advantages of uniform particle size distribution, good compatibility with the substrate, high flame retardant efficiency, strong smoke inhibition ability, low hardness, low friction on equipment, and benefiting on equipment service life prolonging; and after the wastewater produced during the pressure filtration process is treated by the circulation water pool, the water is provided for the two-stage wet grinding, such that the wastewater resource is recycled, and the production cost of the enterprise is effectively saved so as to reduce the environmental pollution.

Description

technical field [0001] The invention relates to the technical field of magnesium hydroxide flame retardant processing, in particular to a processing technology of magnesium hydroxide flame retardant. Background technique [0002] Flame retardants are additives that prevent materials from being ignited and inhibit the spread of flames, preventing a small fire from becoming a catastrophic fire. Magnesium hydroxide is an inorganic flame retardant filler with promising application prospects in polymer matrix composites. Magnesium hydroxide flame retardant is non-toxic and low-corrosion, so it is widely used. Magnesium hydroxide flame retardant relies on chemical decomposition to absorb heat and release water when heated to play a flame retardant effect. Therefore, it has the advantages of non-toxicity, low smoke, stable chemical properties of magnesium oxide generated after decomposition, and no secondary pollution. . However, the production and processing of the existing mag...
