Description
Technical field
The present invention relates to formula and the preparation method of a kind of sebific duct of preventing fires, belong to Waterproof gum pipe preparation field.
Background technology
Fire retardant is to improve material flame resistance, i.e. stops material burned and the auxiliary agent of suppression flame propagation.Due to rubber
Glue material great majority are macromolecular material, for the ease of producing, are required for putting into substantial amounts of inflammable oil product when making formula,
So that reduction rubber hardness, so rubber just becomes inflammable article.Along with industrial development, rubber flame-retarded requirement is therewith
Improving, and more focus on environmental protection and ecological safety, fire retardant is various in style in the market, can be divided into halogen by ignition-proof element
Element, phosphorus element, chlorine element, silicon system, antimony system, boron system, molybdenum system, traditional halogenated flame retardant is because of the poisonous halogenation gas produced when it burns
And human body can be caused secondary injury by smog, two English especially produced, there is carcinogenesis.In halogen-free flame retardants, hydroxide
Aluminum, magnesium hydroxide, APP are important fire retardants, are widely used in rubber, but due to APP self chemistry
Structure, its hygroscopicity is strong, in Vulcanization Process of Rubber, can make rubber pange, have pore, the most also can affect the vulcanization of rubber, fall
The mechanical strength of low rubber.Aluminium hydroxide, magnesium hydroxide add in rubber, are heated and can decompose release water, take away big calorimetric
Gas, thus reduce ignition point and play flame retardant effect.Ordinary circumstance, needs 200 to 300 parts, even if being so also relatively inaccessible to UL94-
V0 rank.
Summary of the invention
It is an object of the invention to: formula and the preparation method of a kind of halogen-free flame-retardant rubber hose are provided, to solve to pass
Human body can be caused secondary injury because of poisonous halogenation gas and the smog produced when it burns by the halogenated flame retardant of system, and existing
Halogen-free flame retardants is not all suitable for problem prepared by flame retardant rubber sebific duct.
For solving the problems referred to above, intending using such a halogen-free flame-retardant rubber hose formula, it is mainly by weighing as follows
The raw material composition of amount part:

Strong agent 30～90 parts, plasticizer 5～45 parts, vulcanizing agent 1～10 parts and fire retardant 10～90 parts.
Most preferably, aforementioned halogen-free flame-retardant rubber hose formula is prepared from by the raw material of following weight portion: EPDM
Rubber 100 parts, zinc oxide 5 parts, stearic acid 1 part, chemical antiager 2 parts, reinforcing agent 50 parts, plasticizer 20 parts, vulcanizing agent 6 parts,
Fire retardant 50 parts.
The zinc oxide used in aforementioned halogen-free flame-retardant rubber hose formula is nano zine oxide, the more common indirect method of particle diameter
Zinc oxide is less, and activity is higher, disperses evenly in rubber, and physical property is more preferable；
The chemical antiager used in aforementioned halogen-free flame-retardant rubber hose formula is quinoline type antioxidant, and quinolines is heat-resisting
Oxygen effect is preferable, affects less on curingprocess rate and physical property, and preferably 2,2,4-trimethyl-1,2-dihyaroquinoline is polymerized
Body；
The reinforcing agent used in aforementioned halogen-free flame-retardant rubber hose formula is N550 white carbon black, increases hardness and the thing of rubber
Rationality energy.Paraffin oil selected by plasticizer, and the ethylene propylene diene rubber compatibility is good, improves process conditions and adjusts hardness；
In aforementioned halogen-free flame-retardant rubber hose formula, sulfur selected by vulcanizing agent, N-cyclohexyl-2-benzothiazole time sulphonyl
Amine, MBT, zinc dibutyl dithiocaarbamate, tetramethylthiuram disulfide, owing to sulfuration promotes
Agent dissolubility in ethylene propylene diene rubber is low, uses for reference multiple a small amount of principle；Sulfenamide type accelerators is delayed action accelerator,
Less avoid the sizing material recovery phenomenon in the process of sulfuration, and promote curingprocess rate, it is ensured that sulfidation
Efficiency and quality；
In aforementioned halogen-free flame-retardant rubber hose formula, fire retardant is by red phosphorus, diphosphorus trioxide, molybdenum oxide, oxidationization two
The compounding composition of antimony, APP, nano-calcium carbonate, calcium carbonate crystal whisker, VTES, Tissuemat E.Phosphorus system is multiple
Zoarium system anti-flammability is strong, and halogen-free and environmental protection, cigarette, phosphorus gas burst size are lower, in elastomeric material, addition is few, it is ensured that relatively
High gum content, affects less on the physical property of rubber.
The preparation method of above-mentioned halogen-free flame-retardant rubber hose is as follows:
By above-mentioned formula by good for raw material weighing stand-by, employing mixer mixing, mixing point two sections:
1. rubber, zinc oxide, stearic acid, chemical antiager disposably put in banburying chamber, plasticate 50 in banbury
60 seconds；
2. after rubber has been plasticated, reinforcing agent, fire retardant are put in banburying chamber, then, make sizing material mixed in banbury
Refining；
3. sizing material is when banburying chamber's melting temperature reaches 88-92 DEG C, is added in banburying chamber by plasticizer；
4. continuing mixing to 140 DEG C binder removals, bottom sheet is cooled to room temperature；
5. the film that will be cooled to room temperature puts in banbury, when sizing material temperature rises to 93 DEG C, is added by vulcanizing agent close
In refining room, pressure bolt 30 seconds, carry position in floating weight and mention dust cover, clean the vulcanizing agent being deposited on floating weight, after having cleaned,
Make sizing material continue mixing, when the sizing material temperature in banburying chamber reaches 100 DEG C, by rotor shutdown switch, mention floating weight and prevent
Dust hood, after putting in place by banburying chamber's upset by tilt switch, by closed-smelting machine rotor operating switches, is discharged to Jiao Chezhong by sizing material；
6. sizing material is put to mill, tabletting, cooling, be filled to store in utensil.
Compared with prior art, major advantage is compounding by multiple halogen-free flame-retardant to the present invention, overcomes tradition resistance
Combustion rubber, containing halogen, fire retardant addition is big, the shortcoming of poor efficiency.The efficient halogen-free element prepared by this formula and method is fire-retardant
Rubber hose can meet the operating temperature requirements of 120 DEG C, and short-term 150 DEG C also can meet, and flame retardant effect can reach GB/T
The FV-0 grade of vertical combustion in 10707-2008, simultaneously the hardness of rubber, hot strength, elongation at break, tearing strength,
Heat-proof aging, resistance to ozone aging, the low temperature resistant General Requirement all meeting each main engine plants.
