Abstract
A novel carbon black and a process for producing the carbon black, wherein the surface characteristics of the carbon black are improved by treating the carbon black with an organic (adsorbate).
Description
When carbon black mixed polymer system, compound moisture absorption (CMA) was that the compound absorption water yield may increase.Improve compound moisture absorption in the conductive polymers and cause two problems deserving of attention to I haven't seen you for ages.At first, during extrusion molding, temperature can surpass 100 ℃ (373 ° of K), and the moisture content that compound absorbs just can evaporate.This evaporation causes producing pore on the extrudate surface, and this is the potential root of dielectric defect.Secondly, the moisture content of compound absorption itself can impel puncture of dielectric by " arc resistance " technology.(described term " arc resistance " comes from the shape of the puncture of dielectric track that microscopic examination sees).
Especially work as some conductive carbon blacks and mix polymer materials, find that compound absorbs the increase of moisture content, main microporosity owing to carbon black.Now, introduce a kind of method, selectively improve the microporosity of carbon black according to the present invention.Handle carbon black with the organic adsorbents that is adsorbed by carbon black, can stop up the micropore of specific dimensions scope effectively, and other character of compound is not had disadvantageous effect.
The applicant determines to handle carbon black with adsorptive, and importantly selected molecular dimension can be filled the adsorptive of selected pore diameter range micropore, stops effectively thus to absorb unfavorable moisture content.It is found that the adsorbate molecules of selection is bonded on the carbon black securely, and under normal handling, storage or service condition, can not break away from.Theoretical assumption is present in the bonding adsorbate molecules of overlapping potential field of aperture like this, has higher energy, makes it to be difficult to replace the molecule in the micropore.
The treatment in accordance with the present invention method can be applicable to the carbon black of any grade effectively, and the effective apearture that this carbon black has energy permeate water molecular dimension scope partly is the surperficial microstructure of feature, can make ball shape or loose carbon granules.Therefore, this treatment process helps to improve the very stove carbon black (nitrogen surface area [N of high surface area
2SA] approximately greater than 140 meters
2/ gram), because these carbon blacks have the feature of effective apearture part in the surperficial microstructure of the size range of regulation.Has N in processing
2About 200 meters of SA
2～260 meters of/grams
2Under the better stove carbon black condition of/gram, reached effective result.
The present invention's (quilt) adsorptive can be the organic molecule that comprises the straight chain that has 4 carbon atoms at least arbitrarily, for example alkane of alkane and replacement (amine, halogenide, alcohol etc.) and composition thereof.Typical material comprise octane, positive amino-octane, n-hexyl alcohol, positive bromo spicy silane, positive chloro-octane, 4-methylheptane, 2,5-dimethyl heptane, 2,3,4-trimethylpentane, 2,2,4-trimethylpentane, hexa methyl ethane, positive nonane, n-decane, n-dodecane, n-hexadecane, 1,3-propylene dichloride etc.For the efficient and the persistence that keep handling in the heat-processed, adsorptive preferably has the straight chain of 10 carbon atoms, especially C at least
10-C
16Normal alkane, their feature is that thermostability reaches more than about 250 ℃ (523 ° of K).
The method that adsorptive is adsorbed onto on the carbon black is not strict.In general, treatment process only comprises the steps, mixes in being about to selected adsorptive amount and carbon black being placed on suitable container, stirs carbon black again, guarantees adsorptive dipping black carbon surface.Adsorptive excessive or that be not adsorbed can carry out drying and get rid of general about 100～200 ℃ of temperature range (373～473 ° of K) the carbon black of having handled under suitable temperature.The treatment process of carbon black also can be incorporated into various processing steps easily during making or utilizing carbon black.For example before collecting carbon black, suitable adsorptive is added the process pipeline of carbon black reactor, or during carbon black and polymkeric substance are mixed together compounding operation, the introducing adsorptive.
The optimum quantity of used adsorptive depends on carbon black to be processed, its surface-area and the percentage that is amassed by micropore surface in the effective size range of blocking of adsorptive of the present invention.When handling conductive carbon black, with about 0.5%～5%(weight) adsorptive realized effective result, and good especially with about 1.0～2.0% adsorptives.
Following embodiment further specifies the present invention.These embodiment are as an illustration in nature, do not limit the scope of the invention.
Test method
The amount of carbon blacks that scale is good adds big mouthful vial, and adsorptive is added on the carbon black jar sealing of lid with the weight percent of measuring then.Rolling jar about 1～5 minute (60～300 seconds) makes bottle interior component fully mixed, and after unliding, component is placed on the baking oven inner drying in jar and the bottle.
In order to estimate that carbon black gives the performance and the volume specific resistance characteristic of compound moisture absorption, combine with carbon black with suitable resin.For the purpose of illustrating, in the following embodiments, (EEA) makes resin with the ethylene-propylene acetoacetic ester, is benchmark with the weight percent, mixes the resins test compound with desired amount of carbon blacks.Specifying under the loading level condition, carbon black is sneaked in the ethylene-propylene acetoacetic ester, have the Brabender mixing tank of turning oil with 60 rev/mins of rotating speeds, in 110 ℃ (383 ° of K) 9 minutes (540 seconds) of mixing down.Be pressed into last compound in cooling on the two-roller mill, and make sheet for follow-up test.
In order to measure compound moisture absorption (CMA), various sheet ethylene/ethyl acrylate (EEA) compound is cut into pieces or the ball shape, to produce suitable granular sample.With the glass pot of 3 gram particle shape compound samples adding known weight, at 60 ℃ ± 3 ℃ (333 ° of K) and 1/3 normal atmosphere (3.4 * 10
4Crust) down dry 2 hours (7200 seconds), the moisture content of eliminating compound.Behind the moisture eliminator internal cooling, the weight that obtains is accurate to 1/10 milligram.Then, compound is put into and is kept room temperature (70 ± 2 [294 ° of K]) and relative humidity 79%(R.H) moisture eliminator reach 48 hours (1.728 * 10
5Second).30 minutes (1800 seconds) back scale compound weight is termly with 24 hours (8.64 * 10
4Second) the interval weighing, until reaching constant weight (water yield that compound absorbs increases by 0.03%).Press the compound weight percent with following formula and calculate the medial humidity that absorbs:
The water yield=((C+S)-(C+DS)-B)/((C+DS)-(TC)) * 100 that compound absorbs
