Description
WATER-BASED CEMENT FOR PRODUCING TYRES
TECHNICAL FIELD
The present invention relates to a water-based cement for producing tyres.
BACKGROUND ART
In tyre manufacturing, cements are normally organic- solvent-based. Cements of this sort are highly adhesive and easy to use, mainly on account of rubber dissolving readily in organic solvents and so blending with other rubber to form practically one piece once the organic solvent evaporates.
For environmental reasons, recent European directives have imposed a drastic reduction in the use of organic solvents in the tyre industry, thus forcing manufacturers to devise alternative solutions to ensure correct adhesion of rubber layers.
One alternative to traditional cements is water- based cements, in which organic solvent is replaced by water as solvent, and which poses the problem of ensuring dispersion in water of intrinsically hydrophobic ingredients. This is done using emulsifiers which, as is known, comprise a hydrophobic group capable of bonding the ingredient in question, and a hydrophilic group capable of ensuring its dispersion in water. Since emulsifiers are normally selectively effective as regards a particular compound, the making of water-based cement calls for using different types of emulsifiers.
Tests show that the presence of large quantities and different types of emulsifiers may impair the adhesive strength of the cement, hence the strong demand for water-based cement emulsifiers that are effective over a wide range of ingredients, to reduce both the quantity and the number of types of emulsifiers used.
The Applicant has surprisingly discovered a particular class of emulsifiers that is universally effective over the various ingredients of water-based cement .
BEST MODE FOR CARRYING OUT THE INVENTION
According to the present invention, there is provided a water-based cement for producing tyres, comprising water as solvent, cross-linkable unsaturated- chain polymer base, sulphur, reinforcing filler, zinc oxide, and accelerators; said cement being characterized by comprising an emulsifier of the general formula (I)
RiCONR2CHR3COOX (I) where : Ri is an aliphatic group C6-C23
R2 is H or an aliphatic group Ci-Cs
R3 is H or an aliphatic or aromatic group Ci-Cs, and
X is a metal cation.
Preferably, the water-based cement comprises by weight 5 to 80% of water, 10 to 60% of a cross-linkable unsaturated-chain polymer base, 0.2 to 1% of sulphur, 1 to 25% of reinforcing filler, 0.1 to 3% of zinc oxide, and 0.1 to 1% of accelerators; said cement being
characterized by comprising 0.1 to 10% of an emulsifier of the general formula (I) .
Preferably, aliphatic group Ri comprises a double bond.
Preferably, the quantity of emulsifier in the cement ranges between 0.5 and 5% by weight.
The examples below are purely indicative and non- limiting, for a clearer understanding of the invention.
EXAMPLES
Six cements A, B, C, D, E, F were prepared. Cement A is a solvent-based cement; cement B is a known water- based cement; and cements C-F are water-based cements in accordance with the invention and employing emulsifiers of formula (I) .
Table I shows the compositions, in percentage by weight, of the six cements.
TABLE I
The standard emulsifiers used in cements B and C are: naphthylsulphonic acid for dispersing zinc oxide,
sulphur, and accelerators; ethoxylated aliphatic amines and ethoxylated fatty acids for dispersing carbon black.
The emulsifier (a) according to the present invention used in cements C and D is sodium oleyl sarcosine of the formula (CH3) (CH2)I8CON(CH3)CH2COONa.
The emulsifier (b) according to the present invention used in cement E is of the formula CH3 (CH2) 7CHCH(CH2) 7CONHCH2COONa.
The emulsifier (c) according to the present invention used in cement F is of the formula CH2CH (CH2) 8CONHCH2COONa .
The emulsifiers used in the cements according to the present invention may differ from those in the above examples. In particular, the group R3 may also comprise heteroatoms such as S, N or 0.
As will be clear to an expert, in addition to natural rubber, the cements according to the present invention may comprise any cross-linkable chain polymer base obtained by polymerization of conjugate dienes and/or aliphatic or aromatic vinyl monomers. For example, usable polymer bases are selected from the group comprising natural rubber, 1,4-cis polyisoprene, polybutadiene, isoprene-isobutene copolymers, possibly halogenated, butadiene-acrylonitrile copolymers, styrene- butadiene copolymers and styrene-butadiene-isoprene terpolymers, both in solution and emulsion, and ethylene- propylene-diene terpolymers. The above polymer bases may be used singly or mixed.
Laboratory tests
Each cement was adhesion-tested on both green and cured rubber, as per ASTM Standard D624, was tested for rheometric properties as per ASTM Standard D5289, and was viscosity-tested as per ASTM Standard D6080. Table II shows the test results.
TABLE II
* The cured rubber was obtained as per ASTM Standard 1382, by curing for 10 minutes at a constant temperature of 1600C.
As shown in Table II, reducing the number of different types of emulsifiers in the cement improves its adhesive strength, so much so that the adhesive strength of cements comprising only one type of emulsifier (cements D-F) is even greater than that of the organic- solvent-based cement (A) .
As shown in Table II, using only one type of emulsifier means a smaller amount can be used, thus improving the stability and adhesive strength of the cement .
Moreover, the double bond in the aliphatic chain Ri further improves adhesion of the cement by participating
in cross-linking reactions.
In short, using a universal emulsifier, different types of emulsifier need no longer be used, and the amount of emulsifier used can be greatly reduced.
As shown by the results in Table II, using an emulsifier as claimed in no way impairs the other characteristics of the cement, such as viscosity and rheometric properties.
