The technical field is as follows:
the invention relates to the field of high polymer materials, in particular to a fire-proof sealant based on synergistic interaction of aerogel and nano-hydrotalcite and a preparation method thereof.
Background art:
in building construction, a large number of mechanical and electrical pipes are criss-crossed between the floor and the wall due to the required functions and structures. Thus, it results in many voids between the floor and the duct, or between the wall and the duct. These pores should be sealed, so that smoke will spread rapidly and expand rapidly in case of building fire. The fireproof sealant is a sealing material for plugging and has double performances of sealing and fire prevention. The existing fireproof sealant is a lot, but the sealant with both excellent fireproof performance and excellent mechanical performance is difficult to meet the requirements of users. Therefore, the development of high-performance sealant is imminent.

The invention also discloses a preparation method of the aerogel and nano-hydrotalcite synergistic fireproof sealant, which is simple to operate and low in preparation cost.
In order to better solve the technical problems, the invention adopts the following technical scheme:
the fire-proof sealant based on synergy of aerogel and nano-hydrotalcite takes sodium silicate and polyisobutylene as matrix adhesives, nano-aluminum hydroxide and nano-magnesium hydroxide as composite flame retardants, nano-calcium carbonate as fillers, modified aerogel and modified nano-hydrotalcite as synergistic agents, and a coupling agent is added; the modified aerogel is prepared by taking silicon/zirconium composite aerogel as a matrix and adding a polymer for crosslinking modification; the modified nano hydrotalcite is prepared by inserting dodecyl sulfonate groups between nano hydrotalcite layers and adding a polymer monomer solution for in-situ polymerization modification.
Preferably, in the technical scheme, the fireproof sealant comprises the following components in parts by weight: 35-45 parts of sodium silicate, 15-20 parts of polyisobutylene, 3-5 parts of nano aluminum hydroxide, 3-5 parts of nano magnesium hydroxide, 20-30 parts of nano calcium carbonate, 1-3 parts of modified aerogel, 2-3 parts of modified nano hydrotalcite and 0.5-1 part of coupling agent.
As a preferred aspect of the above technical solution, the preparation method of the modified aerogel specifically comprises: firstly, adding a silicon source and a zirconium source into a mixed solution of absolute ethyl alcohol and isopropanol, then dropwise adding deionized water for mixing, dropwise adding hydrochloric acid into the mixed solution after uniformly mixing, and adjusting the pH value of the mixed solution to 1-2; stirring and reacting for 1.5-3.5 h at normal temperature, and slowly dropwise adding ammonia water into the reaction system after the reaction is finished to prepare wet gel containing silicon/zirconium; aging the silicon/zirconium-containing wet gel in a water bath at 50-60 ℃, placing the gel in ethanol of a silane coupling agent for standing for 1-4 h, taking out the gel, performing supercritical drying, adding the dried aerogel into an aqueous solution of methyl methacrylate, performing soaking treatment for 2-4 h, adding potassium persulfate, reacting for 2-3 h at 60-70 ℃, and naturally cooling to room temperature after the reaction is finished to obtain the modified aerogel.
Preferably, in the above technical solution, the silicon source is tetraethyl silicate; the zirconium source is zirconium isopropoxide.
Preferably, in the technical scheme, the molar ratio of the silicon source to the zirconium source to the absolute ethyl alcohol to the isopropanol to the deionized water is 1:1:5:5: 7.

preferably, the preparation method of the modified nano hydrotalcite comprises the following steps: adding nano hydrotalcite powder into an ethanol solution of sodium dodecyl sulfate, carrying out ultrasonic treatment, then adding acrylic acid, acrylamide and N, N-methylene bisacrylamide, stirring and mixing, then continuously adding potassium persulfate serving as an initiator, reacting for 2-4 hours at the temperature of 60-80 ℃, and cooling to room temperature after the reaction is finished; filtering, drying the solid obtained by filtering, and grinding to obtain the modified nano hydrotalcite.
Preferably, in the technical scheme, the mass ratio of the nano hydrotalcite powder, the sodium dodecyl sulfate, the acrylic acid, the acrylamide, the N, N-methylene bisacrylamide and the potassium persulfate is 5: 0.001: (0.8-1.2): 0.5:0.001: (0.001-0.003).

The aerogel has good adsorptivity, high activity and good heat-insulating property; and the porous structure of the aerogel can adsorb crystal water released by heating nano magnesium hydroxide and nano aluminum hydroxide, and promote the generation of metal oxide, thereby promoting the formation of a carbonized film on the surface of a flame-retardant object. The nano hydrotalcite material has high activity, interlayer water can be removed when the nano hydrotalcite material is heated, and a large amount of heat is absorbed, so that water vapor is released to dilute combustible gas, and the formation of a carbonized film on the surface of a flame-retardant object is promoted; the fireproof and flame-retardant performance of the sealant is improved.
In the process of preparing the fireproof sealant, firstly, preparing titanium/zirconium-containing wet gel, then, aging the wet gel, and adding the aged wet gel into an ethanol solution of a silane coupling agent for reaction; the titanium/zirconium gel network structure contains a large number of active groups which can be effectively combined with a silane coupling agent, then methyl methacrylate is added, and an initiator is added for reaction, so as to prepare the polymethyl methacrylate modified titanium/zirconium aerogel; the dispersion is good, and the mechanical property is excellent. Although the nano hydrotalcite material has excellent performance, the compatibility of the nano hydrotalcite material and matrix glue is poor; according to the invention, dodecyl sulfonate is inserted between layers of the nano hydrotalcite to increase the distance between the layers, and then the nano hydrotalcite is added into a polymer monomer solution, and the nano hydrotalcite is stripped in the process of polymer polymerization, so that the prepared modified hydrotalcite material has good dispersibility and good compatibility with a matrix. The sealant prepared by the invention has good sealing performance, fire resistance and mechanical property.
