Description
Technical Field
The invention belongs to the technical field of daub, and particularly relates to a preparation method of daub for fireproof sealing.
Background
The daub for fireproof sealing is a flexible flame-retardant material, is used for plugging holes of electric wires and cables, prevents the electric wires and cables from generating fire and spreading to adjacent rooms from the holes, reduces fire loss, avoids the expansion of accidents, and has the functions of smoke resistance, fire prevention, dust prevention and the like, so the daub is widely used for plugging vertical horizontal through holes of the electric wires and cables in system engineering such as power plants, industrial and mining enterprises, high-rise buildings, shipbuilding electric power, post and telecommunications, substations, metallurgy and the like.
The traditional cement for fireproof sealing lacks good viscosity, is easy to solidify and crack after meeting high temperature and low temperature, and is easy to generate holes and gaps to cause temperature or smoke leakage. Therefore, a preparation method of the daub for fireproof sealing is provided.
Disclosure of Invention

the preparation method comprises the following specific steps:
the method comprises the following steps: taking an acrylate monomer, an expanding agent, an emulsifier, a cross-linking agent and an initiator, sending the acrylate monomer, the expanding agent, the emulsifier, the cross-linking agent and the initiator into a reaction vessel, mixing and stirring at 50-80 ℃, then adding an antioxidant, mixing again, coagulating and drying to obtain rubber powder for later use;
step two: sending ceramic powder, starch, diatomite and bentonite to a ball mill for ball milling for 3-7h to obtain powder with the particle size of 3-16 mu m, mixing a dispersing agent and deionized water with the powder to obtain slurry with the solid content of 70-80%, and grinding the slurry after the slurry is solidified to obtain superfine ceramic powder with the particle size of 3-5 mu m;
step three: taking aluminum oxide, ferric oxide, polyisobutylene and magnesium salt whisker, and sending the aluminum oxide, ferric oxide, polyisobutylene and magnesium salt whisker to a ball mill to obtain a composite superfine filler with the particle size of 2-5 mu m;
step four: feeding deionized water, the rubber powder obtained in the step one, the china clay powder obtained in the step two and the filler obtained in the step three into an internal mixer for mixing for 30-60min at a mixing speed of 70-100r/min to obtain a mixture;
step five: mixing the mixture obtained in the fourth step at normal temperature for 4-15min at the mixing speed of 50-65r/min, and adding glass water, chlorinated paraffin and expanded perlite during mixing to obtain a pasty fireproof rubber master batch;
step six: and (3) conveying the muddy fire-proof rubber master batch into an internal mixer shaft, carrying out vacuum treatment in the internal mixer, mixing the muddy fire-proof rubber master batch at the temperature of 95-105 ℃, then stopping heating and vacuum treatment, and continuously mixing for 5-10min at normal temperature to obtain the cement for fire-proof sealing.
Further, in the step one, the emulsifier is sodium alkyl benzene sulfonate or tristyrylphenol polyoxyethylene ether, the cross-linking agent is diethylenetriamine or 2, 5-dimethyl-2, 5-di-tert-butyl hydroperoxide, the initiator is cumene hydroperoxide or tert-butyl hydroperoxide, and the usage ratio of the acrylate monomer, the expanding agent, the emulsifier, the cross-linking agent, the initiator and the antioxidant is 70:0.5:2:0.8:0.3: 0.5.
