Hydrophilic organic solvent
Can use hydrophilic organic solvent substitution list surface-active agent, perhaps use jointly with tensio-active agent.That is to say without tensio-active agent, and use the hydrophilic organic solvent stabilising system.Its consumption generally changes according to the type of dipersant, generally is at least 5%(weight), preferably be at least 10%(weight).Hydrophilic solvent is known to those skilled in the art.Solvent is oxidation solvent preferably.One class oxidation solvent comprises the derivative of the list of 1.2-ethylidene glycol and dialkyl ether, 1.2-.Object lesson has 1.2-ethylidene glycol monobutyl ether, 1.2-ethylidene glycol monobutyl ether acetate ester, 1.2-ethylidene glycol monoethyl ether acetate, 1.2-ethylidene glycol list ether, 1.2-ethylidene glycol dibutyl ether, 1.2-ethylidene glycol monohexyl ether, 1.2-ethylidene glycol monomethyl ether acetate and 1.2-ethylidene glycol monophenyl ether.The solvent of these types generally can the Cellosolve trade(brand)name be buied, and they are made by Union Carbide Corporation.Another kind of oxidation solvent is various aliphatic alcohol, as vinyl carbinol and various 1 solubility alkanol to about 4 carbon atoms, and as methyl alcohol, ethanol, propyl alcohol, Virahol and the trimethyl carbinol.Another kind of oxidation solvent-ketone also can use, as acetone and methylethylketone.Also can use various solubility keto-alcohols, as Pyranton.The hydrophilic organic solvent of these and other type can be used to replace various tensio-active agent of the present invention, or use common with it.
Further conceive according to the present invention, if (B
1) acylating agent has approximately 8 to 30, better is about the substituting group based on alkyl of 8 to 12 carbon atoms, then do not need tensio-active agent and hydrophilic solvent.It is believed that this is that hydrocarbon partly is easy to disperse event because along with the hydrocarbon chain carbon number reduces.Therefore, as long as (B
1) hydrocarbon substituent on the acylating agent is little, the dipersant composition just need not to contain any tensio-active agent or hydrophilic organic solvent.
In fact dipersant composition of the present invention no matter whether contain tensio-active agent or hydrophilic organic solvent, all can use, perhaps wherein contain a certain amount of water, transform emulsion or other system so that form, water wherein is in discontinuous phase, and perhaps water wherein forms external phase.Form the type that the actual used water amount that transforms emulsion or external phase will depend on tensio-active agent, hydrophilic organic solvent, dispersion agent and analogue naturally.The type that forms solution often depends on needed concentration in water, perhaps this fact of water not fully.
Particle and fluid
Aqueous dipersant composition can remain on various particles or liquid in the solution.General available any particle that needs to be suspended, disperse or rise similar effect.For example various clays, talcum, coal, sulphur, silicon oxide, pigment, filler and fiber.This disperser composition unwanted particle of people that is specially adapted to suspend, as cigarette ash, carbon black cigarette ash particularly.When making carbon black, cigarette ash is unavoidably produced as paying product.Because cigarette ash can not be separated in fact at all, thus generally cigarette ash is mixed in the syrup or the lignosulfonate/naphtalene sulfonate aqueous solution, dry then.But in drying process, syrup or lignosulfonate/naphtalene sulfonate can be degraded, and produce the carbon black granules that is difficult for redispersion.According to the present invention, this carbon black dust is easy to be disperseed by the dipersant composition.When drying, the carbon black composition that produces free from dust, unrestricted flow and be highly dispersed.Various products are starved of the particle resemble the carbon black as tire, roof material, pigment and analogue.Another kind of particle is a fiber, and is very little usually, when needs with its suspension or be dispersed in the solution.Therefore, when needs remain on cellulose particulates or plastics in the solution, can in the slurrying operation, use the dipersant composition that contains tensio-active agent or organic hydrophilic solvent.The example of other fiber comprises glass, i.e. analogues such as glass fibre, polyester, nylon, carbon fiber, regenerated fiber, polypropylene fibre.As for fluid, various liquid (as dyestuff, oil and analogue) all can be maintained in the solution.And all gases such as carbonic acid gas and analogue also can be maintained in the solution, for example remains in the solution with form of foam.
Therefore,, just can use this dipersant, optional simultaneously tensio-active agent or the hydrophilic organic solvent of using as long as need or remain in the aqueous solution with particle or fluid dispersion.
Can understand the present invention better with reference to following example.
