Abstract
Wet pigment paste from industrial prodn is mixed with proper composite assistant and passed through kneading, pelletizing and desiccation to obtain particulate pigment. The particulate pigment can be used flexibly as powder pigment but without dust produced, has raised quality and is dispersive in either water or oil.
Description
The present invention relates to a kind of solid surface treatment method, particularly a kind of surface treatment method of pigment wet pulp and special composite assistants thereof.
As everyone knows, the pigment of present industrial use is mainly powder-type, and this is because powder-type pigment has advantages such as thin, the easy dispersion of particle, thereby uses till today.But exist the shortcoming of the environmental pollution (dust from flying of pigment powder is endangering direct labor's health) that is difficult to overcome.Therefore long-term next vast pigment worker is devoted to develop a kind of novel form of pigment, and it had both kept all advantages of powder pigment, can overcome the shortcoming of the environmental pollution of powder pigment again.Unfortunately suffer from not having good plan so far.
The objective of the invention is to propose a kind of working method of granular pigments in order to overcome the above-mentioned shortcoming of powder pigment, it has kept powder pigment all advantages in the use, has overcome the shortcoming of powder pigment dust from flying simultaneously.
Design of the present invention is such:
To come from the pigment wet pulp in the Industrial processes, by adding an amount of special composite assistants, extruder grain after mediating is dried to granular pigments then.Said special composite assistants, its function is: in pigment and auxiliary agent kneading process, form a skim on the pigment particle surface, make pigment keep primary microparticle structure; When granulation, drying, have certain viscosity again, make pigment particle be agglomerated into " granule ", and no longer efflorescence is flown upward; When granular pigments was used, then the effect with auxiliary agent can disperse again easily.
The present invention also is achieved in that
The pigment wet pulp that will come from the pigment wet pulp of wet production or dry production is (during dry production, the water spray can overcome flying upward of pigment dust, and obtain aqueous pigment), wherein water content is 30～80%(wt), after adding special composite assistants, in a kneader, mediated 5～30 minutes, carry out extruder grain then, descended dry 3～8 hours at 105～60 ℃ at last, can obtain the said granular pigments of the present invention.The component ratio of the granular pigments of gained is:
The pigment composition is 80～95%(butt, wt%, down together), special composite assistants is the 20-5%(butt, wt%).
The suitable granularity of granular pigments is 1.5～3.0 millimeters * 2～10 millimeters of Φ (diameter * length).
The said special composite assistants of the present invention is a kind of aqueous composition, wherein contains:

In addition, said special composite assistants has a suitable combination than scope, and the total amount of various auxiliary agents should account for 45～60%(wt), and all the other are water.
On probation according to the granular pigments warp that method of the present invention makes, prove to have following positive technique effect:
(1) overcome fully powder pigment produce and use in owing to the caused environmental pollution of dust from flying.
(2) granular pigments has higher intensity, can bear various external force in the fortune storage process and not efflorescence.
(3) to contain be high to the pigment in the granular pigments, kept powder pigment to use advantage flexibly.
(4) because granular pigments contains the special composite assistants of being made up of hydrophilic gel (water-sol), oleophylic glue (oleosol) and tensio-active agent, so it can disperse at aqueous phase, also can disperse in oil phase.
Experimental results show that: granular pigments of the present invention is placed the Erlenmeyer flask that fills water or organic solvent (as turps, benzene toluene, ethanol, chloroform, ethyl acetate, butanols, diacetone alcohol, dimethylbenzene, pimelinketone, industrial naptha etc.).With Kang Shi oscillator concussion 10-20 minute, pigment can all be disperseed.
Perhaps the someone can suspect; can containing hydrophilic component (water-sol) in the auxiliary agent influence the water resisting property of paint? for this reason; the contriver please do the contrast test by Shanghai Academy of Chemical Engineering, Ministry of Chemical Industry coating; a ready-mixed paint and an alkyd paint sample have been prepared with molybdenum red granular pigments of the present invention; test result: the paint that granular pigments of the present invention is made; its water resisting property; tack; smoothness is all identical with powder pigment (contrasting with the paint of powder pigment preparation); and smoothness also be better than powder pigment (powder pigment in drying process owing to can cause growing up of pigment particle, thereby its dispersing uniformity of shadow)
In a word,, can make pigment in producing, transport the storage use, eliminate the pollution of dust, reduce the generation of industry occupational illness, bring benefit and convenient for production, operation and the user of pigment according to the granular pigments that method of the present invention is made; And can keep pigment microparticle structure in process of production, the raising that has brought the pigment quality.Therefore the method that makes things convenient for of the present invention is a kind of Perfected process for preparing new dustless formulation pigment.
