Definitions
- the invention relates to a two-step method for dipping a synthetic fiber wherein the fiber is first dipped with a pre-dip composition followed by a dip with resorcinol-formaldehyde latex (RFL) composition.
- Fibers such as aramid fibers, that are used to adhere to rubber compounds are commonly subjected to a dipping process for enhancing the bonding of such synthetic fibers to rubber.
- Such compositions may be used in manufacturing composites, for example tires wherein reinforcement fibers are bond to tire rubber compounds.
- rubber composites which include fiber reinforcement in the form of fibers, continuous filament yarns, cords, or chopped fibers, it is important to enhance the adhesion performance between the rubber matrix of the composite and the reinforced fiber materials.
- Aramid fiber for example, is a fiber used for tire reinforcement. Providing adhesion between aramid and rubber is very difficult due to the crystalline surface of the fiber. Hence an active pre-dipping process is necessary in order to get a reasonable adhesion performance between fiber and rubber.
- the standard method of such pre-dipping process is using an epoxy adhesive pre-dipping followed by a resorcinol formaldehyde latex (RFL) dip, which process provides good adhesion to sulfur-cured rubber for aramid reinforcement.
- RTL resorcinol formaldehyde latex
- epoxides and polyethyleneimine have been proposed as adhesion promotors for aramid fibers
- lyengar proposed a two-step adhesive system for aramid fiber adhesion to rubber.
- the first step or pre-dipping should consist of epoxy compound.
- Such pre-dip compositions containing mixtures of polyfunctional isocyanates and diisocyanates have been described in JP 51037174, and containing mixtures of blocked polyisocyanates and clay (such as bentonite) have been disclosed in JP 55062269. None of these compositions, however, were very efficient in adhering rubber and none of these were commercially used.
- the adhesion technology that has been developed since then is virtually always based on the use of epoxides, which is nowadays undesirable because of the ever tightening health care problems and governmental regulations. According to HSE regulations it is undesirable for human body to be exposed to epoxides.
- a two-step method for dipping a synthetic fiber wherein the fiber is first dipped with an aqueous pre-dip composition followed by a dip with resorcinol-formaldehyde latex (RFL) composition, characterized in that the pre-dip composition comprises a blocked isocyanate having at least tri-functional isocyanate groups and a latex wherein the ratio by weight of blocked isocyanate and latex is between 9 and 0.7, preferably between 4 and 1.
- RTL resorcinol-formaldehyde latex
- the pre-dip composition may comprise blocked at least tri-functional isocyanate compound and a latex, which further comprises water, an emulsifier, and 2-vinyl pyridine copolymer.
- the latex part of the pre-dip may be the same or different of the latex part of the RFL composition, and is a block copolymers of a conjugated olefinic block and an aromatic block.
- Such block copolymers are known in the art. It was found that particular good results were obtained when the latex part of the pre-dip and the RFL composition is a vinyl-pyridine block copolymer. Suitable copolymers comprise 2- vinyl pyridine, styrene, and butadiene moieties. Preferably, 10-20% of the units in the copolymer are 2-vinyl pyridine-like structures.
- the method according to this invention can in principle be applied to any synthetic fiber that is commonly used as reinforcement fiber in rubber compositions for tires, transport transmission belts, and the like. Such fibers preferably contain at least one of aramid, polyester, and polyester terephthalate.
- Particularly useful fibers within the context of the invention are fibers containing at least aramid, preferably containing PPTA and/or PPODPTA.
- the method according to the invention is suitable for dipping fibers wherein the fiber is used as spun.
- the blocked isocyanate has at least tri-functional isocyanate groups. Examples of such isocyanates are 1 ,6-hexamethylene diisocyanate (HDI) trimer, etc.
- Blocking groups are known in the art and are selected from ketoxime groups such as methyl ethyl ketoxime, pyrazole derivatives such as 3,5-dimethylpyrazole, esters such as malonic acid esters, caprolactam, and alkylated phenol.
- blocked isocyanate is a blocked HDI-trimer, such as methyl ethyl ketoxime or 3,5-dimethylpyrazole blocked hexamethylene diisocyanate trimer. Most preferred blocking group is 3,5-dimethylpyrazole.
- the RFL dip may contain an emulsifier. Suitable emulsifiers are selected from emulsifiers comprising rubber latex.
- a very suitable pre-dip according to the invention is a composition comprising 2.5 to 4 wt.% of water-dispersed 3,5-dimethylpyrazole blocked isocyanate compound (HDI-trimer), 1 to 2.5 wt.% of 2-vinyl pyridine copolymer (latex) and 90 to 96 wt.% of water (wt.% based on solids). It is essential that the ratio by weight of blocked isocyanate and latex is between 9 and 0.7. Compositions containing too much or too little latex do not give adhesive properties that are comparable with those of the conventional epoxy pre- dips.
- HDI-trimer water-dispersed 3,5-dimethylpyrazole blocked isocyanate compound
- latex 2-vinyl pyridine copolymer
- 90 to 96 wt.% of water wt.% based on solids. It is essential that the ratio by weight of blocked isocyanate and latex is between 9 and 0.7. Compositions containing too much or too little latex
- the invention thus provides a process for adhering aramid fibers to sulfur-vulcanizable rubbers comprising the steps of (1) immersing fibers in an aqueous dispersion which is comprised of (a) 2.5 to 4 wt.% of water-dispersed 3,5-dimethylpyrazole blocked isocyanate compound (HDI-trimer), (b) 1 to 2.5 wt.% of 2-vinyl pyridine copolymer and (c) 90 to 96 wt.% of water to produce coated fibers; (2) drying and curing the coated fibers to produce pre-dipped fibers; (3) subjecting the pre-dipped fibers to a RFL adhesive dip to produce dipped fibers; (4) drying and curing the dipped fibers to produce dipped fibers; (5) placing the cured dipped fibers in contact with a sulfur-vulcanizable rubber; and (6) curing the vulcanizable rubber (wt.% based on solids).
- an aqueous dispersion which is
- the invention in another embodiment relates to fibers and cords, wherein the fibers or cords have distributed over at least a surface portion thereof (1) a blocked tri-functional isocyanate, such as water-dispersed 3,5-dimethylpyrazole blocked isocyanate compound (HDI-trimer); (2) a RFL adhesive; and (3) an in situ vulcanized rubber compound.
- a blocked tri-functional isocyanate such as water-dispersed 3,5-dimethylpyrazole blocked isocyanate compound (HDI-trimer); (2) a RFL adhesive; and (3) an in situ vulcanized rubber compound.
- Example 1 This example provides testing using aramid test sample to show the effect of using a tri-functional blocked isocyanate with 2-vinyl pyridine copolymer together on aramid fibers.
- Adhesives Control adhesive for aramid fiber is a double coat of epoxy and RFL. Aramid fiber was dipped with poly-functional epoxy resin pre-dipping and RFL top-coat for comparison.
- Experimental adhesive (sub-coat) consists of Trixene® Bl 7986 (3,5- dimethylpyrazole blocked HDI trimer; ex Baxenden Chemicals Ltd., UK) at 3.5 wt.% and Pliocord® VP106S (2-vinyl pyridine copolymer latex; ex Goodyear Chemicals Ltd, USA) at 1.5 wt.% (base on solids) as pre-dipped and RFL as top-coat.
- the aramid cord was prepared with construction of 2 ply yarns. 1680 dtex PPTA yarn (Twaron®, ex Teijin) or 1670 dtex PPODPTA yarn (Technora®, ex Teijin) was twisted as Z direction with 330 tpm. By cabling, two twisted yarns were combined and twisted as S direction with 330 tpm.
- This greige cord was dipped in pre-dipping adhesive and dried at 150° C for 120 sec and cured at 240° C for 90 sec, dipped in RFL, and cured at 235° C for 90 sec. Compound for testing Dipped aramid cords were tested in the compound for passenger car tire ply rubber. Main component is natural rubber.
- HDI-trimer/latex dip wt. ratio HDI-trimer/2-vinyl pyridine (Vp) latex
- Adhesion performance SPAF performance was determined with NR rubber and NR/SBR rubber for epoxide/RFL (prior art) and non-epoxide/RFL (invention) in both two-steps and direct cabling, and were shown to be almost the same under all conditions. All values were within the range between 280 and 320 N/2 cm.
- Rubber coverage Rubber coverage was determined as follows. After measuring the peeling adhesion, the peeled surface was observed and the ratio of remained rubber was determined. Results are given in Table III.
