Description
Technical field
The present invention relates to field of nitrile rubber technology of paddling, more particularly to one kind is paddled environment-friendly antirust nitrile rubber.
Background technology
Nitrile rubber is that abbreviation NBR, nitrile rubber mainly uses as made from butadiene and acrylonitrile through emulsion polymerization
Emulsion polymerization at low temperature produces, and oil resistivity is fabulous, and wearability is higher, and heat resistance is preferable, and bonding force is strong, is often used as the soft of pipeline
Property sealing joint, easy for construction, the collection of sewage, conveying are safer.In equipment of paddling, rubber is frequently necessary to and gold
Metal conduit be used together be directly coupled in metal pipe mouth metallic element being embedded in rubber as gasket seal, rubber tube it is first-class
Deng.For General Purpose Rubber product when contacting or combining together with metallic article, rubber does not have corrosion protection effect to metal, is paddling
By the joint effect of the factors such as time, microorganism, pollutant in environment, metal material inevitably easy corrosion, and rubber
Among additive or auxiliary agent also have certain corrosivity to metal.These situations cause the joint of metalwork and rubber to occur
Corrosion, sealing property is influenceed, often scrap, change because of corrosion, cause certain economic loss, while can also contaminant water
Resource.
Chinese patent 201110419962.7 discloses a kind of Rustproof rubber and preparation method thereof, mainly by rubber body
Antirust agent is added in system and reaches rust-proof effect, but the antirust agent used is mainly vapour phase inhibitor, is easily analysed in water environment
Go out, in the equipment that is not suitable for paddling, and the material such as natrium nitrosum, sodium benzoate is also a kind of pollutant in itself, not environmentally friendly enough.
The content of the invention
The defects of present invention is in order to make up prior art, there is provided one kind is paddled environment-friendly antirust nitrile rubber.
The present invention is achieved by the following technical solutions：
One kind is paddled environment-friendly antirust nitrile rubber, includes each component of following parts by weight：NBR 100-150, prevent
Become rusty carbon black 80-100, environment-friendly plasticizer TP-95 15-30, precipitated calcium carbonate 20-35, paraffin 1-2, zinc oxide 5-6, stearic acid
1.5-2.8, sulphur S 1.5-1.8, antioxidant 264 1-2, accelerator CBS 1.5-2.2, accelerator TT 1.5-2.
Described one kind is paddled environment-friendly antirust nitrile rubber, and described antirust carbon black is with containing by hydroxylating carbon black
The environmentally-frieantirust antirust agent of carboxyl is according to 1:The weight of (0.001-0.01) obtains than reaction.
Described hydroxylating carbon black is that carbon black is handled into 5-10h through strong acid carboxylation, and then the carbon blacksurface after carboxylation connects
Branch silane coupler, then will be hydrolyzed in the carbon black input alcoholic solution of grafted silane coupling agent, that is, obtain hydroxylated carbon black.
One or more in the preferred N550 carbon blacks of described carbon black, N770 carbon blacks.
The described environmentally-frieantirust antirust agent containing carboxyl be organic carboxyl acid alcohol amine salt, carboxyl phenylpropyl alcohol triazole, 3- benzoyls-
α-D- glucofuranoses, 3- benzyl-alpha-D- glucofuranoses, 3- acetyl group-α-D- glucofuranoses, 3- dodecanoyl-α-D-
One kind in glucofuranose, Dicarboxy oleic acid acidamide.
Described hydroxylating carbon black reacts actual conditions with the environmentally-frieantirust antirust agent containing carboxyl：Made with tetrahydrofuran or water
For reaction medium, the stirring reaction 2-5h under the conditions of 50-80 DEG C, reaction terminates rear resulting material and washed 3-5 times, after heated-air drying
Sieving.
The present invention by the way that antirust agent is incorporated into nitrile rubber system by antirust agent with the method that carbon black coats, selection
Antirust agent is the environmentally-frieantirust antirust agent of carboxylated, water-soluble or oil-soluble antirust agent, is directly added than traditional antirust agent
The advantages of add mode, is：Using the carboxyl reaction in the hydroxyl and antirust agent of carbon blacksurface after modification, by carbon black with preventing
The strong bonded of rust agent, improves the compatibility of antirust agent and elastomeric material, obtains more long-acting rust-proof effect, effectively
The precipitation of antirust agent is inhibited, elastomeric material is had no adverse effects in itself, effectively inhibits the corrosion of junction metal material,
The service life of metal material is extended, reduces the maintenance cost of metallic article, ensure that the performance for equipment of paddling.
Embodiment
One kind is paddled environment-friendly antirust nitrile rubber, includes each component of following parts by weight：NBR 100, antirust charcoal
Black 80, environment-friendly plasticizer TP-95 20, precipitated calcium carbonate 20, paraffin 1, zinc oxide 5, stearic acid 1.5, sulphur S 1.5, age resistor
264 1, accelerator CBS 1.5, accelerator TT 1.5.
Wherein antirust carbon black is according to 1 by hydroxylating carbon black and carboxyl phenylpropyl alcohol triazole:0.001 weight obtains than reaction
's.
Described hydroxylating carbon black is that carbon black is handled into 5h through strong acid carboxylation, then the carbon blacksurface grafting silicon after carboxylation
Alkane coupling agent, then will be hydrolyzed in the carbon black input alcoholic solution of grafted silane coupling agent, that is, obtain hydroxylated carbon black, wherein carbon black
It is N550 carbon blacks and N770 carbon blacks according to 1:1.5 weight ratio is formulated.
