ADDRESS FOR SERVICE: DAVIES COLLISON CAVE Patent Attorneys 1 Little Collins Street, Melbourne, 3000.
INVENTION TITLE: Emulsifying compositions and acidic bituminous emulsions containing them The following statement is a full description of this invention, including the best method of performing it known to me/us:- P:'OPERJcc\55357-98 spe-doc-09/0/01 -la- This invention relates to an emulsifying composition for bitumen acidic emulsions and to a bituminous acid emulsion. Bituminous mix materials are useful on roads or the like.
The manufacture of cold bituminous mixes by mixing granulates with a bituminous emulsion is an operation which is universally practised. The use of cationic bituminous emulsions, in particular those produced with tallow polypropylenepolyamines, typical of which is tallow propylenediamine, for this purpose is very widespread.
Satisfactory results are obtained, that is to say the formation of an adhesive, continuous film of binder, within a relatively short period of time and with most of the hard materials employed as granulates, and especially with 15 quartzites, porphyric materials, and silico-limestomes.
However, with materials which give a basic reaction, like hard limestones, it very frequently happens that, although
S::
the bituminous coating has been produced in apparently correct conditions, the bitumen film formed by the breaking 20 of the emulsion offers only a very mediocre adhesiveness to the granulate. This is not necessarily obvious immediately, but after definitive drying of the bituminous mix and apart from any mechanic action during this period. It constitutes a threat to the longevity of the structure. Anionic or nonionic bituminous emulsions can not be used as alternatives; these provide coatings which are immediately satisfactory but which do not withstand scrubbing with water. These phenomena have been described, for example 2 in US Patent 3,867,162 (Chevron Research Co), which proposes, specifically for the coating of limestones, the use of a coating emulsion with an appreciably neutral or even plainly alkaline pH which has added to it adhesion-promoters selected from the generic class of tall oils and of various resin acids.
The practical reality of road worksites on a secondary road system and even, quite simply, of roadworks in regions or districts which are not very 10 fortunate with regard to the quality of available granulates, is that alluvial materials are often resorted to. Even if hard materials are aimed at, supplies which are more or less rich in basic components must be reckoned with. What is desired is the ability to have access to coating emulsions that S. give acceptable results whatever the fluctuation in the quality of the materials to be coated. In other words, it must be possible to have access to acidic cationic bituminous emulsions which will properly coat quartzites, porphyries, silico-limestones, limestones and their mixtures. These requirements are collected into specifications which may be regarded as more or less official, since they do not involve instructions relating to works on major systems, and are very frequently derived from ASTM standard D2397 insofar as the emulsion is concerned. This standard imposes a positive charge on the bitumen particles. It is supplemented for the occasion by an additional 3 requirement of a pH of 1.4 to 4 and, for the coating ability by tests which will be found detailed later in the examples.
It has now just been found that it is possible to produce cold bituminous mixes meeting these requirements if the coating material employed is an acidic bituminous emulsion produced with an emulsifier which is a composition of rosin or of a closely related derivative thereof and of one or more alkylamino 10 derivatives selected from the group consisting of alkyl polypropylenepolyamines, alkylamido polymethylenepolyamines and their immediate cyclization 0 derivatives, the alkyl group being a saturated or unsaturated hydrocarbon residue having a carbon atom
*S
content of approximately from 12 to 22, as well as their ethoxylated or propoxylated derivatives.
Mentioned among the alkylamino derivatives most widely employed are technical tallow propylenediamine and tallow dipropylenetriamine as well as their propoxylated derivatives or tallow amidopolyethylenepolyamines or tallow imidazolinopolyethylenepolyamines.
What is intended, within the meaning of the invention, to be meant by rosin or closely related products are resins from the distillation of pine oils, otherwise known as rosins and which contain 90 or more of resin acids of the abietic acid class.
4 The emulsifier according to the invention is a composition comprising the rosin and alkylamino components in a weight ratio of 5/95 to 40/60.
According to a first aspect of the invention, there is provided an emulsifying composition for bitumen acidic emulsions, which composition comprises: from 50 to 100 of a homogeneous mixture of to 95 of an alkylamino derivative or of a mixture of such derivatives, and 10 40 to 5 of rosin or a derivative thereof, and from 0 to 50 of a solvent for the alkylamino derivative(s) and for the rosin or derivative, compatible with bitumen, the alkylamino derivative being selected from the group consisting of alkyl polypropylenepolyamines, alkylamido polymethylenepolyamines and their immediate ring closure derivatives, the alkyl group being a saturated or unsaturated hydrocarbon residue having a carbon atom content of approximately from 12 to 22, and their ethoxylated or propoxylated derivatives.
The emulsifying composition according to the invention may be obtained very easily by mixing powder components, preferably at a temperature not exceeding 700C/800C. The mixture generally assumes the appearance of a wax, a thick liquid or a soft paste of amberlike appearance, which can melt at temperatures below 50 0
C
to a fluid liquid. The melting and holding of the molten product at a reasonable temperature do not impair its physical, physicochemical or chemical properties. In particular, the acid value and the alkalinity remain stable, and this reflects the absence of change in the composition due to an amidation reaction which might be feared between the components.
If desired, the composition can be formulated in a more fluid form by introducing into it a certain quantity of solvent for the amino derivative and for the rosin and, at the same time compatible with the 10 emulsified black binder, for example an anthracenic oil. Accordingly compositions according to the *invention may be such as: 100 to 50 by weight mixture of the rosin and ~alkylamino components in 5/95 to 40/60 weight ratio 0 to 50 by weight solvent.
0The acidic bituminous emulsions which can be produced with the emulsifier of the invention and which 0.
o can be employed for the manufacture of bituminous mixes from materials of all types have otherwise the ordinary compositions of the common bituminous emulsions of the binder-in-water type, namely 50 to 70 of bituminous binder, 0.15 to 0.2 of emulsifier, pH of 1.4 to 4 using hydrochloric or acetic or phosphoric acid.
According to a second aspect of the present invention there is provided a bituminous acid emulsion, of the binder-in-water type, comprising a) 50 to 70 of bituminous binder 6 b) 0.15 to 0.2 of an emulsifying composition according to the invention, c) sufficient acid selected from the group consisting of hydrochloric acid, acetic acid and phosphoric acid for the aqueous phase of the emulsion to have a pH of 1.5 to 4, and d) water to make up the formulation to 100 The bituminous acid emulsions may be prepared without difficulty by following the procedures which 10 are well known to the person skilled in the art for the manufacture of bituminous emulsions with conventional alkylamino emulsifiers. The adjustment of the aqueous phase to an acidic pH is performed with the same acids: hydrochloric, acetic, phosphoric. However, salt formation with phosphoric acid is recommended, the latter being recognized as promoting adhesion of the emulsion to basic granulates.
The following Examples further illustrate the invention.
EXAMPLE 1 a) Preparation of an emulsifying composition parts of tallow propylenediamine (Dinoram® S, CECA hydrochloric alkalinity 6 meq./g) are introduced with stirring into a reactor heated to about 700C/800C, followed by 30 parts of a powdered pine rosin (rosin WWW from the Resineland company, of acid value 165 mg KOH/g and of average molecular mass, measured by GPC in THF, of 270).
7 Stirring is continued until a homogeneous and clear liquid phase is obtained, which sets to a wax from 30 0
C
when cooled. The alkalinity and acid value settle out at 4.2 meq./g and 49.5 mg of KOH/g respectively, values to be expected from the characteristics of the components.
b) Preparation of the emulsion An emulsion containing 69 of bituminous binder is prepared by turbine milling, in a laboratory l1 0 colloid mill and in conditions which are well known to a person skilled in the art, a bitumen of penetration of 60/70 against an aqueous phase obtained by dissolving the emulsifier prepared under a) in water, in a proportion of 2.5 kg of emulsifier per ton of emulsion, and acidifying to pH 2 with hydrochloric acid. The procedure is as follows.
310 parts of water are introduced into a conical flask. 5 parts of the emulsifier prepared in a) above are added with stirring and heating (400C). The mixture is acidified to pH 2 by addition of a 37% solution of hydrochloric acid.
The solution thus obtained is charged into the soap trough of the colloid mill and is heated therein to 50 0 C, while a bitumen of penetration 60/70 is charged into the bitumen trough, where the temperature is raised to 150 0 C. The colloid mill is adjusted for 69 of bitumen, 31 of aqueous phase.
8 An emulsion is thus obtained without any retention on screening and of good stability.
c) Evaluation of the emulsion for its ability to coat hard limestones Into an enamelled dish weigh 461 g of hard limestone materials (Boulonnais quarries) washed and dried, of 0/20 mm particle size. Add 4 g of calcium carbonate to simulate the basic dust which often covers limestone granulates. Homogenize with a spatula. Add o 10 g of the emulsion prepared under Mix the combined materials/emulsion for five minutes. Wash under water.
The materials resulting from this treatment are completely coated. During the mixing no phenomenon of separation of the binder has been observed, nor any loss of coating due to the action of the water.
Evaluation of the emulsion for its ability to coat quartzite The procedure is as under with the difference that the 461 g of granulates are quartzites (Vignat Quarries). The result is completely correct: the materials resulting from this treatment are fully coated.
EXAMPLE 2 (comparative) The above operations are repeated, with the difference that the emulsifying composition is formulated only with 40 g of Dinoram S. With the emulsion prepared with this emulsifying composition the quartzite bituminous mix is correctly coated, but the limestone bituminous mix is laid bare during mixing.
EXAMPLE 3 The operations of Example 1 are repeated, with the difference that during the preparation of the composition a) the Dinoram S/rosin mixture is heated to 150 0 C and kept at this temperature for 4 hours. No appreciable difference is noted either in the 10 appearance of the emulsifying composition or in its characteristics (alkalinity 4.2 meq./g, acid value 49.5 mg KOH/g). The emulsion obtained coats quartzite and limestone as in Example 1.
EXAMPLE 4 The above operations are repeated, with the difference that the emulsifying composition consists of o parts of Polyram SL (a propoxylated tallow propylenetriamine from CECA and of 20 parts of powdered rosin and that the emulsion is prepared with 60 of bitumen 180/220 from an aqueous phase produced partly from this emulsifier and brought to pH 2 with phosphoric acid. The emulsifier content of the emulsion is 4 kg per ton of emulsion.
The coating test results, both for limestone and siliceous materials, are positive.
P:'OPERURcc55357-98 sp.doc-9/08/01 -9a- Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
