Description
Technical field
It is more particularly to a kind of for realization fire-proof smoke insulation mesh outside lock core the invention belongs to lockset and its related accessory field
Gasket assembly and gasket set.
Background technology
With the continuous improvement that fire safety is realized in the development and people of doors and windows sealing industry, people are for door and window
The requirement of leakproofness and fire line is also continuously improved.For window or door when fire, at present, the report of fire proof sealing strip is very much, but
It is, it is fewer for lockset sealing and fireproof report.Ripe to talk about, a thousand li dyke is destroyed in ant cave, even if each side of door and window is all
It has installed fire proof sealing strip additional, still, if string fire or poison gas leakage occurs from the gap of lockset, can also cause entire
Flameproof effect is fallen short of success for lack of final effort.
Fire prevention for lockset, there are also report, still, according to the applicant understood, at present still not to each of lockset
Possible leakage link can play the plugging part of long-term, effective fire-proof smoke-proof effect.For example, CN2690518Y discloses one
Kind novel fire-proof lock, it is disclosed that being internally provided with fire prevention gasket in lock, which is made by easily expanding composite material,
The gap in entire lock can be filled up after heated, notch is equipped in fire prevention gasket, rest part is in the ring bodies of uniform thickness, works as interior
When catching fire, the rapid expanded by heating of fire prevention gasket in lock, fire prevention gasket outer layer seals the gap between lock and door, and internal layer seals
Lockhole had not only prevented the opening, but also barrier flue gas from pouring into interior.But the gasket in the document is single shim form, and this article
It offers the ingredient for not disclosing gasket and is kept without disclosing the flexibility of the gasket before combustion and the shape after intensity, burning
Property.
CN106116600A disclose it is a kind of can ceramic fire-proof sealing material preparation method, for traditional fire prevention calking
Fire resistance is poor, easily hardening cracks in a fire and cannot effectively prevent flame and fire and smoke spread, and putty is in use,
Usually cure due to ageing of binders and environment temperature etc., putty volume contraction forms gap after curing, causes to seal
Block up imprecise problem, provide it is a kind of can ceramic fire-proof sealing material preparation method, which use expansible graphites
As fire retardant, rich silica containing rice husk ashes and diatomite mixing do can ceramic paste, be aided with river sand perlite
Fire resistant infilling, can ceramic fire-proof sealing material up to described in after kneader and silicones mixing.But it is used in the material
The ingredients such as potassium bichromate, ferric nitrate and sulfuric acid, easily cause to corrode to lockset, are unsuitable for for lockset.In addition, for can be swollen
The retentivity of form does not all refer to after the degree of swollen property, flexible degree and burning, while more not referring to multiple performance
Optimization.
CN104610629A proposes a kind of polyethylene anti-flaming material, is prepared by the ingredient of following mass parts:Polyethylene
70-100, carbon forming agent 10-15, borax 10-15, stabilizer 0.01-0.5, hexabromocyclododecane 10-30,8-12 parts of talcum powder help
Solvent 4-10, zinc borate 15-25, color masterbatch 0.1-3, hydroxide 20-40, antimony oxide 1-10, flame retarding polyether 15-20 are even
Join agent 0.05-0.5, expansible graphite 10-20, wood powder 8-15, titanium dioxide 5-10, sucrose 5-10, molybdenum trioxide 1-5.Wherein make
It with polyethylene, but does not refer to the retentivity of form after the degree, flexible degree and burning of expansiveness, does not carry yet
And it can be used for the fire-proof smoke insulation of lockset.
CN104311113A discloses a kind of fire-resistant door core plank, and component and part is:5-30 parts of reinforcing fiber;
2-10 parts of bentonite;6-30 parts of adhesive;10-25 parts of inorganic gel materials;1-12 parts of interfacial agents;Prevent fires expansion plugging material 1-10
Part;0.2-2 parts of waterproofing agent;150-260 parts of water.Wherein interfacial agents have the compatibility and foaming effect for promoting each raw material, gluing
Agent and inorganic gel materials maintain the foam of generation, and reinforcing fiber makes material have certain flexibility and the good machinery strong
Degree.Expansion plugging material is prevented fires when by fire, expansion forms ceramic layer of charcoal, the crack formed when can effectively block plank by fire,
Make door panel material that there is more preferably heat-insulated and barrier fire smoke performance.It is described fire prevention expansion plugging material by ammonium polyphosphate,
Pentaerythrite, expansible graphite, zinc borate are formed, and ammonium polyphosphate and pentaerythrite are heated and easily react to form crosslinking carbon-coating,
Simultaneous reactions and the gas of decomposition generation can expand carbon-coating, and zinc borate can be catalyzed and participate in being expanded into carbon process, make what is formed
Carbon-coating ceramic is expanded, expansible graphite can be expanded into carbon when heated, but carbon-coating is in that wriggling shape is not fine and close, ammonium polyphosphate and boron
Sour zinc can enhance the compactness of carbon-coating while not destroying and being expanded into carbon, and various seams can effectively be blocked by expanding the formation of carbon-coating
Gap.The retentivity of form after the degree of expansiveness, flexible degree and burning is not referred to wherein yet, and also not referring to can be with
For the fire-proof smoke insulation of lockset.
