Abstract
The invention discloses a kind of environmentally friendly oil resistant flame retardant rubber plate and preparation method thereof.The raw material components of environmentally friendly oil resistant flame retardant rubber plate include：Neoprene：70 parts；Nitrile rubber：30 parts；Zinc oxide：4~6 parts；Magnesia：3~5 parts；Stearic acid：1~2 part；Accelerator：0.3~0.5 part；Vulcanizing agent：0.3~0.8 part；Aluminium hydroxide：120~150 parts and colouring agent：1~5 part；The number is mass fraction.The environmentally friendly oil resistant flame retardant rubber plate hardness of the present invention, stretch breaking strength, tear strength properties are excellent, and heavy metal and harmful organic substance content significantly reduce, no carcinogenic substance composition, and fire resistance and oil resistivity lifting are obvious, comply fully with environmentally friendly high fire-retardance requirement.
Description
Technical field
The present invention relates to a kind of environmentally friendly oil resistant flame retardant rubber plate and preparation method thereof, belong to rubber slab field.
Background technology
Rubber is a kind of flexible polymer, and according to the difference for the mode that is made, rubber can be divided into synthetic rubber and day
The class of T PNR two.Fuel gas is also easy to produce because rubber backbone there are an elements such as substantial amounts of carbon, hydrogen, oxygen, during melted by heat, in height
Wen Shiyi burns with oxygen effect.In order to reach fire-retardant purpose, traditional method is a large amount of using halogen containing polymers and addition
Halogen containing flame-retardant.But fire once occurs, substantial amounts of smog and poisonous corrosive hydrogen halides gas can be produced again, caused
The secondary disaster, it endangers often even more serious than direct caused consequence of burning；And existing rubber slab hardness, stretch breaking strength,
Tearing strength etc., is not well positioned to meet requirement, heavy metals exceeding standard, carcinogenic substance content overproof, oil resistance also be present
The defects of poor, need to further it improve.
The content of the invention
Rubber slab hardness, stretch breaking strength, tearing strength are poor in order to solve in the prior art, and heavy metals exceeding standard, carcinogenic substance surpass
The defects of mark, poor flame retardant properties, oil resistivity difference, the present invention provide a kind of environmentally friendly oil resistant flame retardant rubber plate and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted in the present invention is as follows：
A kind of environmentally friendly oil resistant flame retardant rubber plate, its raw material components include：Neoprene：70 parts；Nitrile rubber：30 parts；Oxygen
Change zinc：4~6 parts；Magnesia：3~5 parts；Stearic acid：1~2 part；Accelerator：0.3~0.5 part；Vulcanizing agent：0.3~0.8 part；
Aluminium hydroxide：120~150 parts and colouring agent：1~5 part；The number is mass fraction.
Colouring agent can be carbon black, iron oxide black or their color masterbatch etc. according to color, during black, red be can be iron oxide red,
Rubber is bright red, Lithol Red or their color masterbatch etc., can be everbright fast yellow, medium chrome yellow, permanent yellow or their color masterbatch during yellow
Deng can be that iron is green, dark green or their color masterbatch etc. when green, can be phthalocyanine blue, ultramarine or their color masterbatch etc. when blue.
Unexpected cooperative effect is generated between the above-mentioned each raw material components of the application, so that Natural rubber sheet is hard
Degree, stretch breaking strength, tearing strength etc. have obtained the improvement of highly significant, and heavy metal and harmful organic substance content significantly drop
Low, fire resistance and oil resistivity are obviously improved, and comply fully with environmental requirement.
In order to further promote the cooperative effect between each component, weatherability, anti-flammability, the hardness of product are further improved
With the performance such as tearing strength, it is preferable that vulcanizing agent is sulphur.
It is excellent in order to be further ensured that mechanical property, environmental-protecting performance and the oil resistance of the environmentally friendly oil resistant flame retardant rubber plate of gained
Select, acrylonitrile mass content >=25% in nitrile rubber.
In order to further promote the cooperative effect between each component, mechanical performance, the fire resistance of product are further improved
And oil resistance, it is preferable that accelerator 1,2- ethylene thioureas or N- cyclohexyl -2-[4-morpholinodithio base sulfenamide.
The production method of above-mentioned environmentally friendly oil resistant flame retardant rubber plate, including following steps connected in order：
The first step：By neoprene and nitrile rubber input banbury banburying 1-2 minutes, add zinc oxide, magnesia,
Stearic acid, aluminium hydroxide and colouring agent continue banburying 4-5 minutes, then discharge to mill bottom sheet, cross water cooling, and suspension is dried in the air
It is dry；
Second step：By first step resulting material in banbury heat refining 1-2 minutes, then addition accelerator and vulcanizing agent banburying
30 ± 3 seconds, dumping to mill continued to turn refining uniformly, slice；
3rd step：Film obtained by second step is put into vulcanizing press or drum vulcanizer, is 140 DEG C -170 in temperature
DEG C, pressure vulcanizes under conditions of being 5-15mpa, produces environmentally friendly oil resistant flame retardant rubber plate.
The NM technology of the present invention is with reference to prior art.
The environmentally friendly oil resistant flame retardant rubber plate of the present invention has the improvement of highly significant, such as lead, chromium, mercury in terms of environmental-protecting performance
It is zero that content of beary metal, which reduces the carcinogenic substance content such as highly significant and PBBs,；And good mechanical performance, fire resistance and resistance to
Oiliness lifting is obvious, environmentally friendly high fire-retardance requirement is complied fully with, so as to further widen the use of neoprene and nitrile rubber
Scope.
