Abstract
Rubber is contacted with a surfactant, coated with a polymeric composition comprising a colouring agent and then dried to form a solid coloured coating thereon. The surfactant may be applied as an aqueous solution which is subsequently allowed to at least partially dry on the surface of the rubber. The polymeric composition typically comprises an acrylic polymer or copolymer emulsion, optionally with a further modifying resin eg. a polyurethane dispersion and a pigment. The colouring method is particularly applicable for colouring comminuted scrap rubber, which may subsequently be used as synthetic mulch, as a soil amendment, or as a safety ground surface for childrens play areas and the like.
Description
IMPROVEMENTS IN AND RELATING TO COLOURING METHODS
Field of the Invention
This invention relates to methods of colouring rubber and rubber produced thereby.
Background of the Invention
The environmental disposal of scrap Lyres has become of great concern in many countries around the world over the last few years. The rubber component of Lyres generally takes a very long time to degrade naturally by way of natural bacteria and other micro organisms, and thus disposal in landfill sites can lead to large Lyre mountains, which are both aesthetically displeasing, and can present a fire hazard.
However, burning of tyres is generally considered unacceptable, as the combustion gases and combustion products of burnt Lyres are considered environmentally damaging.
It has therefore been proposed, and is an ongoing concern, to improve the quality of the environment by grinding scrap Lyres into small particles and converting them into useful products. The ground Lyre pieces have been used for fuel, back fill materials to facilitate drainage around structural foundations, additives to enhance the surface characteristics of various materials used in road construction, soil amendments to provide soil compaction, building products such as roofing and weatherproofing systems, and recreational safety surfaces.
Ground Lyre particles are also commonly used in landscaping mulch and playground safety surfaces, with the latter use particularly effective as the rubber is compressible, and thus children falling on to rubber surfaces have less chance of injuring themselves than on comparable playground surfaces such as concrete.
For rubber chips used in landscaping and recreational safety surfaces, it is generally desired to colour the rubber particles in order to make them more aesthetically pleasing. Efforts have been made to address the demand for coloured surfaces by coating rubber particles in paint or other colouring solutions. However, it is an ongoing problem to provide a coating composition and rubber particles coated therewith, in which the coating composition adequately adheres to the rubber for long periods of time. Known methods of coating rubber particles with paints or pigment solutions generally produce coloured particles in which the colour coating can quickly become abraded or ablated. Consequently, it would be advantageous to provide an effective method of colouring rubber particles that provides a durable and uniform colour coating on the particles, and in which the colouring has excellent abrasion resistance.
It is therefore an aim of preferred embodiments of the present invention to overcome or mitigate the problems of the prior art, whether expressly disclosed herein or not.
Summary of the invention
According to a first aspect of the invention there is provided a method of colouring rubber, the method comprising the steps of: (a) first contacting the rubber with a surface active agent; (b) coating the rubber with a polymeric composition comprising a colouring agent; and (c) drying the coated rubber to provide a solid coating thereon.
Suitably the surface active agent is an anionic surfactant, cationic surfactant, non-ionic surfactant, amphoteric sufactant or a zwitterionic surfactant.
Preferably the surface active agent is an anionic surfactant.
Suitable anionic surfactants include, for example, linear or branched C8 to C16 alkyl sulphonates, C8 to C16 alkyl sulphates, C8 to C16 alkyldiphenyloxide disulphonates, and C4 to C16 alkylated naphthalene sulphonates. Examples of suitable anionic surfactants include sodium lauryl sulphonante and sodium dodecyl benzene sulphonate, or mixtures thereof, and compositions comprising anionic surfactants supplied under the trade names LISAPOL (RTM) and TEPOL (RTM), by Shell UK, UK.

Examples
The various embodiments of the invention will now be described by way of non limiting example in which the following materials are used: LISAPOL (RTM) - a detergent composition comprising an anionic surface active agent (surfactant), supplied by Shell UK, UK.
TEPOL (RTM) - a detergent composition comprising an anionic surfactant, supplied by Shell UK, UK.
NEO-RESR984 (RTM) - an adduct resin consisting of a hard amine-free polyurethane dispersion in water manufactured by NeoResins, Waalwijk, the Netherlands. - l

Example 1
A recycled Lyre Dunlop SP10 Passenger Tyre was ground into particles having a length of approximately 20mm. The ground particles were passed over a magnetic table to ensure the removal of any residual magnetic metal within the Lyre.
The rubber chips were pre-washed in a 1% W/W solution of surfactant comprising LISAPOL or TEPOL, in water. The rubber chips were then passed over a vibrating screen and the LISAPOL and TEPOL surfactant solutions sprayed onto the vibrating chips, in order that all the available surface of all of the chips was coated in the surfactant solution. The pre-wash in surfactant solution was necessary to increase the adhesion qualities of the rubber chip, and after the chips had been coated with the surfactant, the rubber material was allowed to dry for such a length of time that the majority of the water from the surfactant solution was evaporated, whilst allowing the rubber to retain a percentage of the moisture content, approximately 5-10% of its initial water content. The moisture was reduced by using a heat exchanger, giving four volumetric air changes per minute at 20 C.
After pre-washing in surfactant solution and the above mentioned drying step, the rubber chips were placed on a second vibrating table and a formulation comprising 90% (W/W) of Dulux Eggshell paint and 10% (W/W) NEO-RES was sprayed onto the vibrating pre-washed rubber chips, until all available surface of the rubber chips were coated.
The Dulux paint comprises colouring agents in the form of pigments, and any suitable coloured Dulux paint can be used, depending on which colour a user wishes the rubber to have.
After the coating operation, a drying sequence was performed using a vibrating table present within a heating lo tunnel into which hot air was injected for, which heating helped to evaporate some moisture from the acrylic co- polymer water based emulsion, and accelerated curing of the emulsion.
The resultant polymer coated rubber particles had excellent abrasion resistance. Furthermore, the acrylic polymer coated rubber particles exhibited excellent adhesion between the rubber and acrylic polymer coating.
The product was subjected to normal outdoor weather conditions in Manchester, UK for a twelve month period.
During which time, it was also subjected periodically to extreme hot and cold temperature -20 C - +40 C. The rubber chips retained 100\ elasticity and zero colour degradation.
