Description
Technical field
The high displacement performance fire prevention silicone sealant and preparation method thereof that the present invention relates to a kind of suitable for skyscraper, belongs to
In fire prevention silicone sealant field.
Background technique
Common silicone sealant is one of the sealant of common building joint sealing, common silicone sealant it is main
Raw material is that linear polysiloxanes, the main chains such as 107 glue are mainly made of Si-O-Si key, in the curing process crosslinking agent and basis
The webbed structure of polymer reaction shape, and Si-O-Si key bond energy be higher than ultraviolet light bond energy, therefore silicone sealant relative to
For other kinds of sealant, there is excellent caking property, weatherability and uvioresistant.Since 107 glue are at 200-300 DEG C
Burn, and the fire of skyscraper easily collapses after having fast sprawling, evacuating personnel difficulty, building burning, difficulty of saving is big
The characteristics of, therefore each producer develops fireproof gum to meet building for fireproof requirement.
Fireproof gum refers to the sealant for joint seal for there is fire protection requirement.It is compared with common silicone sealant,
It is few when fire prevention silicone sealant is with burning that cigarette is nontoxic, combustion heat value is low, flame propagation velocity is slow, it is complete to be able to maintain in a fire
The characteristics of property and thermal insulation.Fireproof gum has not required nothing more than good anti-flammability, caking property, displacement capacity, watertightness and longer
Service life also requires glue-line not collapse, free from flaw, is pierced by without flame, and unexposed surface temperature is less than 180 DEG C.Displacement capacity refers to
Be insert seam sealant adapt to seam be displaced and keep the deflection effectively sealed.If than certain sealant have ±
25% displacement capacity, when glue-line width is 12mm, then it represents that the glue-line of this sealant can bear original width 25%
It stretches and compresses, i.e., it at most can be compressed to 9mm, be stretched to 15mm.Therefore, the displacement capacity of sealant is higher, can bear
Deflection it is also bigger, be more suitable for the facilities such as super high-rise building joint filling, large-sized concrete facility, road, bridge, airfield runway
The sealing of concrete extension joint.
Fireproof gum must have an anti-flammability first, fireproof gum by be added fire retardant to achieve the effect that fire-retardant, fire retardant
Fire retardant mechanism have at 4 points: 1, heat-absorbing action；2, covering acts on；3, inhibit chain effect；4, non-flammable compressive gas smothering action, and it is practical
There are several fire retardant mechanisms to work simultaneously in upper many fireproof gums.Outstanding fireproof seal gum does not require nothing more than self-extinguishing without fire, also
It is non-fusible, do not drip, be not ashed, not dusting it is required that ceramic forms hard shell after combustion, keep building element complete
Property, continue to play gap plugging action, prevents flame and smog from spreading from gap.
Chinese invention patent application prospectus CN106350001A discloses a kind of the organic of ceramic at high temperature
Silicone sealant and preparation method thereof, the organosilicon sealant include matrix resin, reinforcing agent, silane coupling agent, catalyst, fill out
Fill powder, wherein filling powder by glass powder, fire retardant and helps porcelain agent to form, help porcelain agent be selected from di-iron trioxide, titanium dioxide,
One of antimony oxide, silicon carbide, mica powder, magnesium phosphate and diatomite are a variety of.Although the invention has fire-retardant sealing
The self-extinguishing fire retardancy of glue, and can not be ashed under high temperature, that is, fire condition, not dusting, ceramic occurs, after continuation of insurance
Sealant plugging action is held, building element integrality is effectively kept.But there is also following deficiencies for the silicone sealant: displacement energy
The demand of the not high enough fireproof gum for not being able to satisfy skyscraper of power.
Chinese invention patent application prospectus CN103160239A discloses high displacement capacity silicone fireproof seal gum
And its manufacturing method, first by α, alpha, omega-dihydroxy polydimethyl siloxane, dimethyl silicone polymer, inorganic filler, nitrogen-phosphorus system resistance
Combustion agent is added in kneader, dehydration be blended it is cooling after obtain base-material, at room temperature, by the base-material be added to planetary mixer or
In high velocity dispersators, then will be in fumed silica, multiple crosslinking agent, silane coupling agent, catalyst addition blender
It reacts that high displacement capacity silicone fireproof seal gum is made with base-material one.Although the invention fire protecting performance is good, have good
Caking property and water-fast caking property, displacement capacity up to 25 grades, curtain wall normally stretch and shear-deformable situation under, can play
The sealant of effect acts on.But there is also following deficiencies for the silicone sealant: displacement capacity is not high enough be not able to satisfy skyscraper,
The even fireproof gum demand of super high-rise building.
In order to cater to the demand in market and the development trend of future architecture, suitable for high-rise, even super high-rise building
Fireproof gum is one of the hot spot of research and development.
Summary of the invention
The present invention has made improvements in view of the above-mentioned problems of the prior art, i.e., the technical problem to be solved by the present invention is to mention
For a kind of high displacement performance fire prevention silicone sealant and preparation method thereof suitable for skyscraper, the fire prevention silicon that the present invention obtains
The displacement capacity of ketone seal gum is stronger, is more suitable for applying in high-rise, super high-rise building sealing.And the present invention obtain it is anti-
Ceramics turn to hard shell after fiery silicone sealant burning, and the shell is not molten in fire hazard environment and do not drip, in fire
In play firm protective effect, not only keep the integrality of building, building burning will not be made to fall and injure people by a crashing object, also can avoid
The diffusion of poison gas dense smoke after burning.
