Description

SPECIFICATION Rubber/fabric composite manufacture Technical field This invention relates to rubber/fabric composite manufacture and in particular to methods of bonding fabric to rubber in forming such a composite.
Background art In many industrial applications, such as in drive belts, fluid conducting hoses, etc., it is desirable to reinforce a rubber body with a suitable fabric. In one such application, the reinforced rubber element is subjected to oil and the like. The device may further be subjected to high temperature conditions in normal use. One such environment is that found in connection with hoses and drive belts, such as used in vehicle engine apparatuses, and the like.
Recently, a rubber known as hydronitrile rubber has been developed which is both oil and temperature resistant. Such rubber has found wide use in such applications.
However, in order to provide high thermal resistance, hydrogen has been added to the rubber to saturate the double bond thereof to prevent recoupling of the rubber at high temperature with sulfur. Further, it has been conventional to minimize or eliminate the use of sulfur in the rubber compound. This, however, presents the serious problem of loss of adhesion of the reinforcing fabric to the rubber, as such adhesion conventionally has relied upon the presence of sulfur in the rubber compound.
Disclosure of invention The present invention comprehends a novel solution to the problem of fabric adhesion to the rubber without requiring the presence of sulfur in the rubber compound.
More specifically, the invention comprehends the improved method of bonding a fabric to a rubber compound including the steps of subjecting the fabric to a liquid containing acrylonitrile-butadiene-latex and a resorcinol-formalin mixture wherein the solid weight ratio of the acrylonitrile-butadiene-latex to the resorcinol-formalin is in the range of from approximately 10 to 1 to aproximately 2 to 1,the mol ratio of resorcinol to formalin is in the range of from approximately 1 to 3 to approximately 3 to 1, and the acrylonitrile-butadiene-latex contains at least approximately 3% carboxyl groups, and vulcanizing unvulcanized high temperature-resistant hydronitrile rubber in association with the fabric.
In the illustrated invention, the fabric may comprise a wide range of different fabrics, including cotton, rayon, poylvinyl alcohol, aliphatic polyamide, aromatic polyamide, polyester, glass, etc.
In the illustrated embodiment, the mol ratio of resorcinol to formalin is in the range of approximately 1 to 1 to approximately 2 to 1.
In the illustrated embodiment, the solid weight ratio of acrylonitrile-butadiene-latex to resorcinol-formalin is in the range of approximately 8 to 1 to approximately 4 to 1.
In the illustrated embodiment, the fabric is pretreated by subjection to a solvent selected from the group consisting of isocyanate solvent, epoxy solvent, mixtures thereof, etc.
In the illustrated embodiment, the pretreated fabric is dried prior to subjection thereof to the mixture liquid.
In the illustrated embodiment, the fabric is heat treated following the subjection thereof to the mixture liquid and prior to the vulcanization of the hydronitrile rubber in association therewith.
In the illustrated embodiment, the heat treatment step is carried out at a temperature in the range of approximately 140"C to approximately 210"C.
The heat treatment step, in the illustrated embodiment, is conducted for approximately 2 minutes.
The drying of the pretreated fabric, in the illustrated embodiment, is carried out at a temperature lower than the temperature at which the heat treating step is carried out.
The novel method of bonding a fabric to a hydronitrile rubber in forming a composite thereof is extremely simple and economical while yet providing an improved rubber/fabric composite wherein the fabric is strongly bonded to the rubber, notwithstanding the minimization or elimination of sulfur in the rubber compound. Thus, the improved rubber/fabric composite is adaptable for use in oily and high temperature environments.
Brief description of the drawing Other features and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing wherein: Figure lisa graph illustrating the relationship of the mol ratio of resorcinol in the liquid mixture relative to the adhesive or peeling strength of the bond between the fabric and hydronitrile rubber in the manufacture thereof in accordance with the invention hereof; Figure2 is a graph illustrating the correspondence of the solid ratio of resorcinol/formalin to latex in the liquid mixture relative to the adhesive or peeling strength; and Figure 3 is a graph illustrating the relationship of the carboxyl group content of the acrylonitrile-butadienelatex relative to the adhesive or peeling strength of the composite.
Best mode for carrying out the invention In the illustrative embodiment of the invention, a rubber/fabric composite is manufactured by a novel method wherein the fabric is bonded to the rubber compound so as to have high adhesiveness, or peeling strength, while yet permitting the rubber to have low sulfur content and thus, constitute a high temperature resistance rubber. Thus, the rubber/fabric composite of the present invention is ideally suited for environments wherein the composite is subjected not only to oil, but also to high temperatures while yet maintaining high adhesiveness between the reinforcing fabric and the rubber of the composite.
In describing the invention, the preferred rubber member of the composite comprises a high temperature-resistant hydronitrile rubber and, thus, one which has low or zero sulfur content. The present invention provides high adhesiveness of the fabric thereto by treating the fabric in one or more steps prior to the vulcanizing of the rubber in association therewith.
More specifically, the fabric to be used in the composite may comprise any suitable fabric, such as one formed of cotton, rayon, poyvinyl alcohol, aliphatic polyamide, aromatic polyamide, polyester, glass, etc., fibres or yarns.
The invention comprehends subjecting the fabric to a liquid containing acrylonitrile-butadiene-latex and a resorcinol-formalin mixture wherein the solid weight ratio of the acrylonitrile-butadiene-latex to resorcinolformalin is in the range of approximately 10 to 1 to approximately 2 to 1.
In the illustrated embodiment, the mol ratio of resorcinol to formalin in the mixture is in the range of approximately 1 to 3 to approximately 3 to 1.
In the illustrated embodiment, the acrylonitrile-butadiene-latex preferably contains at least approximately 3% carboxyl groups.
In the illustrated embodiment, the fabric is pretreated prior to subjecting it to the liquid mixture. In the pretreatment, the fabric is subjected to a solvent selected from the group consisting of isocyanate solvent, epoxy solvent, and liquid mixtures thereof.
In a preferred form, the mol ratio of resorcinol to formalin in the fabric treating liquid is in the range of approximately 1 to 1 to approximately 2 to 1.
In a preferred form, the solid weight ratio of the acrylonitrile-butadiene-latex to resorcinol-formalin in the liquid mixture is in the range of approximately 8 to 1 to approximately 4 to 1.
In the illustrative embodiment, the fabric is preferably dried prior to the step of subjecting it to the latex liquid mixture. The drying is preferably carried out at an elevated temperature.
In the illustrative embodiment, subsequent to the subjection of the fabric to the latex liquid mixture, the fabric is heat treated by subjection thereof to a temperature in the range of approximately 140 to 210"C.
In the preferred embodiment, the heat treatment step is carried out at a temperature in the range of approximately 1 90 C to approximately 200"C for approximately two minutes.
In the preferred embodiment, the temperature at which the fabric is dried subsequent to the pretreatment step is preferably lower than the temperature at which the fabric is heat treated following subjection thereof to the latex liquid mixture.
In the illustrative embodiment, where the fabric is formed of aromatic polyamide fiber, the drying step is preferably carried out at a temperature in the range of approximately 1 80"C to approximately 1 90"C.
It has been found that notwithstanding the elimination of the pretreatment step, the subjection of the fabric to the latex liquid mixture prior to the vulcanization thereof with the hydronitrile rubber provides improved high adhesiveness and peel strength.
Bonding of the treated fabric to the hydronitrile rubber is effected by associating the treated fabric to unvulcanized high temperature-resistant hydronitrile rubber and vulcanizing the rubber while maintained in association with the fabric.
Industrial applicability The rubber/fabric composite formed by the novel method of the present invention is advantageously adapted for use in the manufacture of transmission belts, conveyor belts, hoses, etc., where oil and high temperature conditions may be present. In one example of rubber/fabric composite manufacture embodying the invention, a fabric formed of aromatic polyamide Kevlar fiber cord was composed of 1 500D/1 x 4 in a latex liquid mixture, as set forth in Table I below. It was subjected to the liquid mixture for 2 minutes at 200"C.
The cord was then spun onto an adhesive tape wound around a drum on which hydronitrile rubber compound 3mm thick was laminated. The laminated sampie was vulcanized for 30 minutes at 105"C and the sample was cut to 1 wide test strips for measurement of the adhesive characteristics, or peel strength of the fabric relative to the rubber. The test was run at a tension speed of 50mm per minute, using a peeling tester manufactured by Shimadzu Corporation of Japan, comprising an Autograph tester thereof.
