Description
Technical field
The invention belongs to chemical technology field, specifically, is a kind of paraffinic base rubber softening oil and preparation method thereof.
Background technology
Butyl rubber is elastomeric a kind of, by iso-butylene and a small amount of isoprene synthetic multipolymer.It drops into industrial production in nineteen forty-three.The butyl rubber finished product are difficult for gas leakage, industry and civilian in widespread use.Generally be used for making the inner tube of a tyre of automobile, aircraft wheel.
Rubber oil is to be only second to rubber and the third-largest material of sooty in the rubber industry as the Plasticising system of rubber track.The main rubber articles factory that supplies allocates the oil plant that in rubber, uses when producing rubber item.Be mainly used in the making adhesive waterproof coil, as tenderizer, weighting agent, softening agent etc.
One, rubber oil classification:
1 difference by the use object can be called rubber filling oil, rubber processing oil, RX etc. respectively.
The difference of 2 paraffinic bases, aromatic base, naphthenic rubber oil:
3 is different by the difference of the molecular structure of MO own, composition aspect: be divided into paraffinic base rubber oil, oily, the aromatic base rubber wet goods of naphthenic rubber;
1) paraffinic base rubber oil is anti-oxidant, light stability good, but emulsifying property, consistency and the low temperature properties of paraffinic base rubber oil are relatively poor;
2) aromatic base rubber oil compatibility is best, and the gained rubber product is high by force, but add-on is big, and is cheap, but its color is dark, it is big to pollute, toxicity is big, along with the raising of environmental requirement will progressively be eliminated;
3) naphthenic rubber oil then has paraffinic base, aromatic base characteristic concurrently, and emulsifying property, consistency are well pollution-free again, toxicological harmless, and the rubber clone of adaptation is more, have wide range of applications, and be ideal rubber oil product kind therefore.
Two, rubber oil salient features:
Improve the processing characteristics of rubber; Power consumption when refining is rolled in saving; Improve with the dispersion of other Synergist S-421 95s and mix; Reduce the production cost of rubber; Reduce the hardness of cross-linked rubber; Improve the performance (like tensile strength, elongation, winter hardiness, resistance to elevated temperatures, raising color stability etc.) of cross-linked rubber.
1. rubber oil characteristic:
1) rubber oil viscosity: the rubber oil viscosity is high more, and then fluid is got over thickness, and rubber oil is all influential to the rerum natura of the processing characteristics of sizing material and cross-linked rubber.Adopt the low rubber oil of viscosity, lubrication is good, and winter hardiness improves, but in that to add man-hour volatilization loss big.
2) specific density: the specific density of RUBBER PROCESS OIL is just very important when rubber item is sold by weight.Generally, the aromatic hydrocarbon oil specific density is greater than the specific density of alkane oil and naphthenic oil.
3) aniline point: generally speaking, rubber oil aniline point is more suitable in 35～115 ℃ of scopes.
4) pour point (yield point): this characteristic can be represented the suitability to goods operating procedure temperature.
5) the flash-point rubber oil flash and the vulcanization of rubber, storage and fire preventing have direct relation, also can weigh the rubber oil volatility simultaneously.
6) neutralization value: the acid obvious delay that can cause vulcanization of rubber speed greatly.
In addition, the specific refractory power of fluid, appearance color, volatile matter also can both reflect its composition situation.
2. the condition that desirable rubber oil should possess:
Consistency is good; Volatility is few; Processibility, operability, oilness are good; The physicals of cross-linked rubber there is not bad influence; Emulsifying property is good; Pollute less, nontoxic; Light colour, good security; The source is sufficient, moderate cost.
Three, rubber oil selects for use
1. select principle for use: the rubber oil of selecting to suit according to kind, rubber production technology and the rubber product characteristics of rubber.Usually adopt the similar compatibility principle.
2. note problem when using:
1) come into operation before, must oil original in the equipment be discharged, and equipment rinsed well, in case cause oil product color and oil quality change of stability with fresh oil;
2) therefore the rubber of different trades mark oil should not mix use because of variant with the flexibility of rubber;
3) the rubber oil of different manufacturers production must just can be replaced use after the evaluation through oil-filled test of rubber and rubber use properties earlier, had better not mix use.
Four, rubber oil is to the Rubber processing Effect on Performance
1. to mixing influence: rubber is relevant to pick up the oil speed and oil composition, viscosity, mixing condition: general viscosity is low, aromatic hydrocarbon content is high, temperature is high, absorbs soon.But oily consumption is many, makes the dispersed variation of carbon black in rubber, must add in batches.In addition, add oil when mixing, can reduce to give birth to heat, cut down the consumption of energy.
2. the influence to extruding: add an amount of oil in the sizing material, can make sizing material softening, extrusions smooth surface, extrusion are expanded little, and extruder rate is fast.
3. sulfurized is influenced: along with the increase of oils loading level in the sizing material, vulcanization rate has the tendency of slowing down.The adding of oil reduces vulcanizing agent, the promotor concentration in rubber, and vulcanization rate is slowed down.Contain the many rubber oil of aromatic hydrocarbon oil, the effect that promotes sizing material incipient scorch and accelerated cure is arranged.
Because in the existing rubber item, the shared proportion of butyl rubber is higher, and existing rubber oil and butyl rubber generation chemical action, thereby is not suitable for the tenderizer of butyl rubber.Existing rubber oil also has the not good shortcoming of consistency, also because of volatility causes damage greatly, can not satisfy environmental requirement in addition.
Summary of the invention
The objective of the invention is to, a kind of paraffinic base rubber softening oil is provided, not good to overcome the above-mentioned consistency of existing in prior technology, volatility causes damage greatly, and the shortcoming that can not satisfy environmental requirement.Be mainly used in the making adhesive waterproof coil, as tenderizer etc.
Another object of the present invention provides a kind of preparation method of paraffinic base rubber softening oil.The present invention makes through underpressure distillation, dewaxing, sulfonation, technology such as refining with paraffinic crude.
