Abstract
A bitumin substitute synthetic plastics material binder is disclosed which includes at least one natural rosin, a mixture of two or more synthetic plastics materials and suitable lubricants or thickeners. The binder can be suitably coloured or compounded with aggregates and/or mineral fillers to form a synthetic paving or sealing material. The binder can include recycled plastics material and the binder itself and the paving or sealing materials can be recycled.
Description
SYNTHETIC PAVING OR COATING MATERIAL This invention relates to a synthetic binder for paving or coating materials and relates particularly to a synthetic binder for paving or coating materials which can be used as a substitute for known bituminous materials but which includes no bitumen whatsoever. The invention relates also to a method of manufacture of such binders and to paving or coating compositions made therefrom.
The binder of the invention can be varied in composition to provide a composition which varies in hardness from that of a roofing binder material to that of a conventional mastic asphalt or that of a conventional asphaltic concrete. The binder is furthermore pigmentable.
Bituminous paving materials are well-known in Australia and would constitute the most common road surfacing materials in Australia whether in the form of a bituminous/aggregate paving material or in the form of a bituminous hot mix material. A disadvantage of currently known bituminous paving materials is that they are subject to undesirable softening under harsh Australian conditions which results in a movement or creep of the paving material under conditions of frequent usage.
It is an object of the invention to provide a synthetic binder composition to replace bituminous binder compositions.
It is also an object of the invention to provide paving or coating compositions utilising such a binder composition.
The present invention therefore provides a binder composition comprising : one or more natural gums or rosins, a mixture of two or more synthetic plastics materials; and a lubricating and thickening agent.
Preferably the natural rosin is selected from Chinese gum, ester gum rosin, terpene rosin and cumarone rosin and is present in an amount of from 30 to 60 % by weight of the binder.
Preferably the synthetic plastics materials are selected from synthetic resins, thermoplastic elastomers, polyethylene, ethyl vinyl acetate polymer i.e. polyethylene, polypropylene, polybutylene, polyvinylbutyral, or a nitrile j- or monomer resin, butadiene/styrene or butadiene/isoprene copolymers and are present in an amount of from 15 to 50% by weight of the binder. These synthetic plastics materials may be, as will be readily apparent, recycled synthetic plastics materials. 10 Preferably the lubricating and thickening agent is a mixture of oils and thickeners selected from petroleum oil, castor oil, flux oil and paraffin oil (paraffinic oil) and hydroxy methyl cellulose, hydroxy ethyl cellulose, lithium grease and silicon grease and is present in an -5 amount of from 10 - 50% by weight of the binder.
The binder can be mixed with aggregates or fillers to provide a suitable paving material or by variation of the relative amounts of the ingredients, provide a binder suitable for use as a roofing material (sealant), as a
20 mastic asphalt or as an asphaltic concrete. Suitable aggregates are crushed rock or minerals, sand, and the like. The binder preferably constitutes from 5 to 20% w/w of the paving material but it is stressed that the relative of binder and aggregate/filler may be varied within wide ranges depending on the particular intended use of the paving or
25 coating material. The paving or coating material may be formed into various shapes for use as building or cladding materials in addition to being used as paving materials for road- and path-ways and sporting arenas and can itself be
30 recycled.
Pigments or other colouring materials may be added in an amount of from 1 to 5% w/w of the total binder composition.
The following non-limitative Examples serve to ,_ illustrate the binders of the invention.

The binder is prepared by melting the Chinese gum, adding the polybutylene polyvinyl butyral, nitrile and ionomer resins are added with stirring at a temperature of about 175°C. The elastomer is then added followed by the paraffin oil. The hydroxyethyl cellulose is then added slowly and stirring continued until a homogeneous binder mixture is obtained. Mixing is effected with a conventional ribbon mixer. A binder suitable as a paving binder is produced.

The binder compositions can be used in place of conventional bituminous compositions, ϋncoloured, coloured or pigmented binders and compositions can be made having increased strength and hardness especially suitable for hot climates.
The binders of the present invention can be prepared by addition of the various components in the order shown in the following Tables and at the temperature ranges given by utilisation of a conventional ribbon mixer as described in Example 1.
