Description
Technical field
The present invention relates to sealed strip technical field.
Background technology
Along with the raising that development and the quality of life of doors and windows sealing industry require, people are also more and more higher for the sealing requirements of door and window.Sealed strip plays as sound insulation, dust-proof, 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 Wood-door window.Such as adopt doors and windows sealing technology, the 20-30% that can economize on electricity, noise reduction 50-80%, room temperature promote 3-8 DEG C, and install sealed strip additional and can effectively prevent door and window to be out of shape, and increase the service life.
Sealed strip is generally extruded by materials such as PVC, modified PVC, Ethylene Propylene Terpolymer, elastic body sealing strip (TPV, TPE, TPR, SEBS), silica gel and is formed.But above-mentioned materials can reduce the material performance of itself under the high temperature conditions, and the toxic substance of release, major polluting atmosphere environment, affects HUMAN HEALTH; Due to sealed strip large usage quantity in doors and windows sealing, fire meeting self-burning met by PVC sealed strip, during presence of fire, do not have isolation fireproofing function, can increase the intensity of a fire on the contrary and discharge dense smoke and toxic gas, even causing secondary disaster, being therefore in use restricted.
Summary of the invention
The invention provides a kind of fireproof flame-retardant expansion sealing strip, can not self-burning when meeting high temperature and naked light, energy automatic expansion, shutoff crack between a door and its frame gap, intercept the air circulation in two spaces, effectively prevent the early stage dense smoke of fire, toxic gas and hot gas to the harm of human body, and effectively control fire spreading, prevent the condition of a disaster from expanding.
The technical solution used in the present invention is:
A kind of fireproof flame-retardant expansion sealing strip, be made up of the raw material of following weight proportioning:
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, be made up of the raw material of following weight proportioning:
Resin-oatmeal: 20 parts
Expanded graphite 20 parts
28 parts, calcium carbonate
Dibutyl phthalate 15 parts
Dioctyl phthalate (DOP) 3 parts
6 parts, paraffin
Ferrocene 2 parts
Ammonium octamolybdate 2 parts
Antimonous oxide 2.5 parts
Zinic stearas 0.3 part
Barium stearate 0.3 part
Lead sulfate tribasic 0.4 part
Dibasic lead phosphite 0.5 part
Calcium carbonate is preferably light calcium carbonate.
In resin-oatmeal, add ammonium octamolybdate and ferrocene, can play the effect of fire protection flame retarding, prevent 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 the dehalogenation reaction in early days, and slow down linked reaction, forms heavy graphite-like coke.At resin-oatmeal/MoO
3combustionresidue in have the molybdenum of 90% to stay in Graphitic coke.In resin-oatmeal, add the raw smoke which of ammonium octamolybdate material can reduce by 69%, also improve oxygen index 3-10 unit simultaneously.
(2) resin-oatmeal burning takes off in the process of HCl, and first ferrocene generates FeC1
2with FeC1
3, be converted into a-Fe rapidly
2o
3be present in charring layer, simultaneously FeC1
2with FeC1
3generation absorb again a large amount of HCl, effectively inhibit the toxic gas that resin-oatmeal discharges.Thus solve 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 unchanged.
Expanded graphite take crystalline flake graphite as raw material, processes through chemistry or electrification a kind of compound between graphite layers obtained.Expanded graphite is under heating condition, and volume sharply expands (reaching as high as 300 times), and suffocate flame, generates dilator simultaneously, reaches isolated flame, and postpone or interrupt the effect of propagation of flame, and itself does not fire, 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, when a fire its can automatic expansion 4-6 doubly, shutoff door and window gap, hinders entering of flame and obnoxious flavour, thus reaches sealing effectiveness.
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, stirring in homogenizer, is flour after stirring.Flour after stirring is joined in extruding granulator, 100-120 DEG C of extruding pelletization, then add after forming machine goes out machine and obtain finished product.
Sealed strip of the present invention, directly can pulverize through crusher and reclaim, easily realize reaching recycling.
Fireproof flame-retardant expansion sealing strip designed by the present invention, is applicable to the door leaf of various steel door and wooden door and doorframe, between door leaf and door leaf.Sealed strip of the present invention can expand along with the rising of temperature, have the advantages that burning-point is high, meet fire expansion, the material energy automatic expansion arrived involved in the present invention when a fire, shutoff door and window gap, hinder entering of flame and obnoxious flavour, thus reach sealing effectiveness, effectively prevent the early stage dense smoke of fire, toxic gas and hot gas are to the harm of human body and control fire spreading, for fire protection and rescue gains time.
Adopt light calcium carbonate to make weighting agent, make sealed strip have waterproof, insulation, light, sturdy and durable, the special performance such as slipperiness is high attractive in appearance.
The beneficial effect adopting technique scheme to produce is:
Fireproof flame-retardant expansion sealing strip of the present invention, can not self-burning when meeting high temperature and naked light, energy automatic expansion, shutoff crack between a door and its frame gap, intercept the air circulation in two spaces, effectively prevent the early stage dense smoke of fire, toxic gas and hot gas to the harm of human body, and effectively control fire spreading, prevent the condition of a disaster from expanding.
