Abstract
The invention discloses a fireproof flame-retarding expansion sealing strip and belongs to the technical field of sealing strips. The fireproof flame-retarding expansion sealing strip is composed of the following materials in parts by weight: 18-25 parts of resin powder, 15-24 parts of expanded graphite, 25-33 parts of light calcium carbonate, 12-18 parts of dibutyl phthalate, 1-4 parts of dioctyl phthalate, 3-8 parts of paraffin, 1-3 parts of ferrocene, 1-3 parts of ammonium octamolybdate, 2-5 parts of antimonous oxide, 0.2-0.5 part of zinc stearate, 0.2-0.5 part of barium stearate, 0.2-0.6 part of tribasic lead phosphate and 0.2-0.8 part of dibasic lead phosphate. The fireproof flame-retarding expansion sealing strip provided by the invention does not combust automatically when meeting high temperature and open flame, and can expand automatically to block a crack to cut off the ventilation of two spaces, so that the damage to human bodies caused by dense smoke in the early stage of a fire disaster, poisonous gas and hot gas is effectively prevented, and the spreading of fire is effectively controlled and the situation of the disaster is prevented from expanding.
Description
Technical field
The present invention relates to the sealed strip technical field.
Background technology
Along with the development of doors and windows sealing industry and the raising of quality of life requirement, people are also more and more higher for the sealing requirements of door and window.Sealed strip plays as sound insulation, dustproof, antifreeze, warming, waterproof and the effect such as energy-conservation in plastic-steel door and window and bridge-cut-off aluminum door and window and timber window.For example adopt the doors and windows sealing technology, the 20-30% that can economize on electricity, noise reduction 50-80%, room temperature promote 3-8 ℃, and install sealed strip additional and can effectively prevent the door and window distortion, increase the service life.
Sealed strip is generally extruded and is formed by materials such as PVC, modified PVC, Ethylene Propylene Terpolymer, elastic body sealing strip (TPV, TPE, TPR, SEBS), silica gel.But the material performance of above-mentioned materials meeting minimizing under hot conditions itself, and the toxic substance discharged, major polluting atmosphere environment, affect HUMAN HEALTH; Due to sealed strip large usage quantity in doors and windows sealing, the PVC sealed strip is met fire meeting self-burning, during presence of fire, does not have the isolation fireproofing function, can increase on the contrary the intensity of a fire and discharge dense smoke and toxic gas, even causes secondary disaster, therefore in use is restricted.
Summary of the invention
The invention provides a kind of fireproof flame-retardant expansion sealing strip, can self-burning when meeting high temperature and naked light, the energy automatic expansion, shutoff crack between a door and its frame gap, intercept the circulation of air in two spaces, effectively prevented the harm to human body of the early stage dense smoke of fire, toxic gas and hot gas, and effectively controlled fire spreading, prevented that the condition of a disaster from enlarging.
The technical solution used in the present invention is:
A kind of fireproof flame-retardant expansion sealing strip, by the raw material of following weight proportioning, made:
Resin-oatmeal: 18-25 part
Expanded graphite 15-24 part
Calcium carbonate 25-33 part
Dibutyl phthalate 12-18 part
Dioctyl phthalate (DOP) 1-4 part
Paraffin 3-8 part
Ferrocene 1-3 part
Ammonium octamolybdate 1-3 part
Antimonous oxide 2-5 part
Zinic stearas 0.2-0.5 part
Barium stearate 0.2-0.5 part
Lead sulfate tribasic 0.2-0.6 part
Dibasic lead phosphite 0.2-0.8 part
Preferably, by the raw material of following weight proportioning, made:
Resin-oatmeal: 20 parts
20 parts of expanded graphites
28 parts, calcium carbonate
15 parts of dibutyl phthalates
3 parts of dioctyl phthalate (DOP)s
6 parts, paraffin
2 parts of ferrocene
2 parts of ammonium octamolybdates
2.5 parts of antimonous oxides
0.3 part of Zinic stearas
0.3 part of barium stearate
0.4 part of lead sulfate tribasic
0.5 part of dibasic lead phosphite
Calcium carbonate is preferably light calcium carbonate.
Add ammonium octamolybdate and ferrocene in resin-oatmeal, can play the effect of fire protection flame retarding, prevent that sealed strip from running into high temperature and being placed in fire and producing toxic smog, its smoke suppression mechanism is:
(1) ammonium octamolybdate can limit the formation of benzene derivative in condensed phase, and molybdenum compound, as a kind of Lewis acid, can make resin-oatmeal accelerate in early days the dehalogenation reaction, and slow down linked reaction, forms heavy graphite-like coke.At resin-oatmeal/MoO
3combustionresidue in have 90% molybdenum to stay in the graphite coke.In resin-oatmeal, add the ammonium octamolybdate material to give birth to the cigarette amount and can reduce by 69%, also improve an oxygen index 3-10 unit simultaneously.
(2) in the process of the de-HCl of resin-oatmeal burning, at first ferrocene generates FeC1
2with FeC1
3, be converted into rapidly a-Fe
2o
3be present in charring layer, simultaneously FeC1
2with FeC1
3generation absorbed again a large amount of HCl, effectively suppressed the toxic gas that resin-oatmeal discharges.Thereby solved the toxic gas discharged when fireproof flame-retardant expansion sealing strip runs into high temperature or is placed in fire, but the use properties of product and the coefficient of expansion are unchanged.
Expanded graphite be take crystalline flake graphite as raw material, through chemistry or electrification, processes a kind of compound between graphite layers obtained.Expanded graphite is under heating condition, and volume (the reaching as high as 300 times) flame that suffocates that sharply expands generates dilator simultaneously, reaches isolated flame, postpones or interrupts the effect of propagation of flame, and itself do not fire, and flexibility is good.Fireproof flame-retardant expansion sealing strip of the present invention adds proper amount of expanded graphite, increases the expansion character of sealed strip, and when presence of fire, doubly, shutoff door and window gap, hinder entering of flame and obnoxious flavour, thereby reach sealing effectiveness its energy automatic expansion 4-6.
Fireproof flame-retardant expansion sealing strip production technique involved in the present invention is as follows:
Resin-oatmeal, expanded graphite, light calcium carbonate, dibutyl phthalate (DBP), dioctyl phthalate (DOP) (DOP), paraffin, ferrocene, ammonium octamolybdate, antimonous oxide, Zinic stearas, barium stearate, lead sulfate tribasic, dibasic lead phosphite are mixed according to aforementioned proportion, in homogenizer, stirring, is flour after stirring.Flour after stirring is joined in extruding granulator, 100-120 ℃ of extruding pelletization, then add forming machine to go out after machine finished product.
Sealed strip of the present invention, can directly pulverize and reclaim through crusher, easily realizes reaching recycling.
The fireproof flame-retardant expansion sealing strip that the present invention is designed, be applicable between the door leaf and doorframe, door leaf and door leaf of various steel doors and wooden door.Sealed strip of the present invention can expand along with the rising of temperature, have the advantages that burning-point is high, meet the fire expansion, the material energy automatic expansion arrived involved in the present invention when presence of fire, shutoff door and window gap, hinder entering of flame and obnoxious flavour, thereby reach sealing effectiveness, effectively prevented the early stage dense smoke of fire, toxic gas and hot gas harm the control fire spreading to human body, for fire protection and rescue gains time.
Adopt light calcium carbonate to make weighting agent, make sealed strip there is waterproof, insulation, light, sturdy and durable, the special performance such as slipperiness is high attractive in appearance.
The beneficial effect that adopts technique scheme to produce is:
Fireproof flame-retardant expansion sealing strip of the present invention, can self-burning when meeting high temperature and naked light, the energy automatic expansion, shutoff crack between a door and its frame gap, intercept the circulation of air in two spaces, effectively prevented the harm to human body of the early stage dense smoke of fire, toxic gas and hot gas, and effectively controlled fire spreading, prevented that the condition of a disaster from enlarging.
