Definitions
- the present invention relates to a composition comprising a fine powder and more particularly, though not exclusively, 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.
- GB2291600 discloses a mix comprising a colourant powder and a particulate material, for example, sand, which mix has improved flowability
- Airborne powder can give rise to health problems, losses and cause cross contamination thereby affecting the quality of coloured products.
- Granular versions of pigments have also been produced and are typically made by a process involving pre-dispersion followed by spray drying. This process is very expensive and is suitable only for long runs and large
- the granules are often not of a particularly resilient nature and tend to break down easily on handling, conveying and metering. This has the effect of re-creating the dust and handling problems associated with 'powders' .
- fine powder is releasably bound to the particulate material with a
- the coating agent is a liquid, more preferably a wetting-agent and more preferably still a non-drying wetting agent.
- the coating agent functions by displacing the air from about the particle, maximising the amount
- the preferred coating agents comprise hydrophilic groups the fine powder can be easily displaced from the particle by the addition of water.
- the fine powder will typically have a particle size (diameter) of from O.Ol ⁇ to 10 ⁇ .
- the fine powder is preferably a colourant and may comprise one or more pigments such as, for example, red iron oxide, yellow iron oxide, black iron oxide, carbon and phthalocyanine blues-greens etc.
- the particulate material will typically have a particle size (diameter) of greater than 20 ⁇ . More preferably it will have a particle size (diameter) ranging from 20 ⁇ - 500 ⁇ with a mean particle size (diameter) of about lOO ⁇ .
- the particulate material is preferably an ingredient of the end product to be produced.
- Preferred particulate materials for use in a composition for use in the building industry include sand and limestone, although other particulate materials, such as microsphere, which have little or no effect on the properties of the end product can be used.
- the end products to be produced for use in the building industry include, for example, paving blocks, roof tiles or bricks, and will typically contain 0.5 to 5 % by weight of a colorant.
- the coating agent is added in an amount of 0.1 to 15 % by weight based on the weight of the composition.
- the coating agent allows the particulate material to be wholly or partially coated by the fine powder, alleviating many of the problems associated with the use of fine powders.
- the preferred coating agents are wetting agents, more particularly non- drying wetting agents and more particularly still surfactants.
- Preferred coating agents are carboxylated surfactants, sorbitan esters, alcohol ethoxylates, alkylphenol ethoxylates and sulphonates.
- a method of preparing a composition of the invention comprising wetting the particulate material with a coating agent and releasably binding the fine powder to the coated particulate material.
- the fine powder is coated to the particulate material using a coating agent in an amount of 0.1 to 15% by weight based on the weight of the composition.
- the coating agent is an ethoxylated surfactant.
- a method of producing a product for use in the building industry, comprising from 1-5 % by weight of a fine powder and one or more other ingredients characterised in that the fine powder is added to the other ingredients as a composition of the invention.
- the particulate material (sand) was placed in a low intensity mixing chamber, the coating agent (ethoxylated surfactant) added, mixed and the fine powder (colourant) gradually added.
- the components were subjected to further mixing and then packaged. Mixing was by way of a tumbling action and at a circumferential speed of between 0.2 - 1.2 metres per second, more preferably at 0.7 m sec "1 .
- Samples of each composition were placed in a clear plastic vial, shaken and the degree of "dusting" determined visually.
- the samples were characterised on a scale of 1 to 5. 1 was used if the vial wall remained clear on shaking, indicating a lack of dusting (good coating of fine powder (colorant) to particulate (sand)) and 5 was used if a dense layer of fine powder formed on the vial wall on shaking (poor coating of fine powder (colorant) to particulate (sand)).
- the bulk density was also determined and is given as the amount in Kgs occupied by 1 litre volume.
- single coating agent could be replaced by a number of components so long as the fine powder is releasably bound to the particulate material such that the fine powder can be readily dissolved or dispensed in water.
