Abstract
The present invention relates to a composition comprising a fine powder and more particularly, though not exlusively, to a composition in which the fine powder is a colorant. Such compositions have particular use in the construction industry for colouring building materials, particularly cementitious products, mortar, asphalt and tarmac. The composition comprises a fine powder and a particulate material, the fine powder being releasably bound to the particulate material with a coating agent. The invention also discloses a method of making the composition and a method of making an end product with the composition.
Description
The present invention relates to a kind of composition that comprises fine powder, relate in particular to but be not limited to, wherein fine powder is a kind of composition of tinting material.This composition has unique purposes in building industry, can be used to material of construction painted, especially painted bonded product, mortar, pitch and pitch.
Yet though should recognize that the usefulness tinting material is as described fine powder in the example, disclosed the present invention also can be applicable under other situation, and wherein the processing of fine powder exists the following problem of listing with reference to tinting material.
GB2291600 discloses a kind of mixture, comprises a kind of tinting material powder and a kind of granulate material, and such as sand, this mixture has the mobile of improvement and more is difficult for blockage ratio such as pneumatic and mechanical transmission line than tinting material powder itself.
Though this mixture is a very big improvement than using the tinting material powder, and is unsatisfactory, because the fine powder in the mixture still can cause obstruction and float in the air.The pigment loading level also can be restricted.
Float over airborne powder and can cause health problem, loss and crossed contamination, thereby influence the quality of color-tinted product.
Because these problems, industrially attempted using liquid colourant, these are higher than powder cost, and have a large amount of shortcomings that comprise in being deposited in.They also freeze in the winter time easily, easily do stolen goods when overflowing, and can not use by the wet aggregate in the concrete floor file is laid bricks.
Also produced particulate pigment, its preparation process comprises spraying drying pre-dispersed and subsequently usually.This process is very expensive, is only applicable to long-term operation and produces solid color pigments in enormous quantities.These particles do not have special elastic property usually, easily in processing, transmission, fragmentation when measuring.This can produce dust again and bring the processing problems relevant with ' powder '.
The object of the present invention is to provide a kind of composition, said composition can overcome the one or more described problem relevant with the fine powder product in the existing technology.
According to an aspect of the present invention, provide a kind of composition, said composition comprises a kind of fine powder and a kind of granulated material, it is characterized in that adopting a kind of coating that fine powder and granulated material are releasably bonded together.
Preferred described coating is a kind of liquid, is more preferably a kind of wetting agent, also is more preferably a kind of wetting agent of non-dryness.The effect of coating is, by excluding air around particle, allows to bonded fine powder amount maximum.
Because preferred coating comprises hydrophilic group, be easy to just fine powder to be removed from particle by adding water.
Usually granular size (diameter) scope of fine powder is 0.01 micron to 10 microns.
Fine powder is preferably a kind of tinting material, and can comprise one or more pigment, for example red iron oxide, iron oxide yellow, iron oxide black, carbon black and phthalocyanine blue-green etc.
Usually the granular size (diameter) of granulated material is greater than 20 microns.More preferably its granular size (diameter) scope is 20 microns-500 microns, and its median size (diameter) is about 100 microns.
Granulated material preferably has the composition of the finished product that will produce.Though other performance for the finished product has seldom or do not have the granulated material such as the microballoon of influence also can use, the preferred granulated material that can be used in the composition that building industry uses comprises sand and Wingdale.From this respect, the finished product that are applied to the production of building industry comprise and comprise the tinting material of 0.5～5 weight % usually as floor file building block, roof tiles or brick.
Preferably make the relative granulated material maximization of fine powder amount,, promptly obtain fine powder and saccharoid weight proportion greater than 1: 1 to reduce transportation cost.For reaching this target, be the coating that base adds 0.1～15 weight % with the composition weight.
Coating makes that granulated material is all or part of to be coated by fine powder, has alleviated and uses the relevant a lot of problems of fine powder.
Fine powder according to character of producing used tinting material in the bonded product and their manufacturing process, but has been found that preferred coatings should make fine powder be bonded on the granulated material with delivery mode, so that can discharge under aqueous environments.
Preferred coating is wetting agent, is non-dryness wetting agent and tensio-active agent more preferably also especially.Preferred coatings is carboxylated tensio-active agent, Isosorbide Dinitrate, the ethoxylate of alcohol, the ethoxylate and the sulfonate (ester) of alkylphenol.
The Isosorbide Dinitrate of ethoxylation that wherein has the height ethoxylation, promptly ethylene oxide content is that this compound of 10-20 finds that after deliberation effect is very good.
Provide a kind of method for preparing the present composition more on the other hand according to of the present invention, comprised and adopt the wetting granulated material of a kind of coating, but and make fine powder be bonded to the granulated material of coating with delivery mode.
With described composition weight is base, and the coating of employing amount 0.1～15 weight % is coated to fine powder on the granulated material.
Preferred coatings is the tensio-active agent of ethoxylation.
According to of the present invention again on the other hand, the method of a kind of production application product in building industry is provided, this product comprises fine powder and one or more other components of 1-5 weight %, it is characterized in that fine powder is added in other component, as composition of the present invention.
Only,, further introduce the present invention with reference to following manufacture method, composition and test data by example.
Production method
Granulated material (sand) is placed in the low-density mixing section, adds coating (tensio-active agent of ethoxylation), mixing, add fine powder (tinting material) gradually again.These components encapsulate subsequently through remix.Mixing is to realize that by the cylinder effect its circumferential speed is positioned at the 0.2-1.2 meter per second, more preferably 0.7 meter per second.
