本発明はゴムベルト、タイヤ等のゴル製品の補強用に用
いるゴム補強用ｔａａの処理剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention relates to a treatment agent for rubber reinforcing TAA used for reinforcing golf products such as rubber belts and tires.
（従来の技術）
ゴムベルト、タイヤ等のゴム製品の強度を増大させる為
、ガラスミｍヤーン等の補強ｍ維が広く用いられる。(Prior Art) In order to increase the strength of rubber products such as rubber belts and tires, reinforcing m-fibers such as glass fiber m-yarn are widely used.
ゴムベルト等のゴム製品は繰返し屈曲応力を受けるため

果を得るためには、補強繊維とゴムとの馴染み、接着力
を大きくする必要があり、このため補強繊維表面に処理
剤が塗布される。Rubber products such as rubber belts are subject to repeated bending stress, resulting in bending fatigue and performance deterioration. Peeling occurs between the reinforcing material and the rubber matrix, reinforcing fibers wear out, and strength decreases easily. In order to prevent such peeling and obtain a sufficient reinforcing effect, it is necessary to increase the compatibility and adhesion between the reinforcing fibers and the rubber, and for this purpose, a treatment agent is applied to the surface of the reinforcing fibers.

耐熱性を有する処理剤は知られていない。Treatment agents with various compositions have been proposed, but the bond strength between the reinforcing material and the rubber matrix is large, and the strength decreases even when subjected to repeated stress, or the bonding strength between the reinforcing fibers and the rubber matrix is large. A processing agent that does not cause peeling and has sufficient heat resistance is not known.

点があった。(Refer to Japanese Patent Application Laid-open No. 55-114551.) By using such a treatment agent, the reinforcing material and rubber 71
- Is it possible to make the bonding force (adhesive force) between the waxes sufficiently large?If subjected to repeated bending stress, the strength may decrease, or the reinforcing fibers and the rubber matrix may easily separate [111], which may shorten the lifespan. It has the drawbacks that the length is short, the heat resistance is low, and the reinforcing layer is easily worn out, resulting in a decrease in strength.

い。If the ratio of fluororesin latex to rubber latex in the mixture thus obtained (treatment agent of the present invention) is smaller than the above range, the effect of the present invention may not be sufficient, and if the ratio of fluororesin latex is too large. It becomes less compatible with the rubber matrix, and sufficient adhesion cannot be obtained.

る。Although there are no particular limitations on the reinforcing fibers to which the treatment agent of the present invention is applied, it is practical to use glass fibers. For example, three glass fiber bundles of about 200 glass fibers with a thickness of 9IL added with a sizing agent are arranged in a row, followed by a conventional method.
The treatment agent of the present invention was applied and dried, and a 2.54 cm (
The S or Z twist (pre-twist) of about 0.5 to 4.0 per inch (2.54 cm) is further aligned by about 2 to 13 pieces to create a twist of about 0.5 to 3.0 per 2.54 cm. , yarns that are twisted in the opposite direction to the first twist (first twist) can be suitably used.

と思われる。(Function) Since the treatment agent of the present invention contains fluororesin latex, the heat resistance is improved and there is a friction-reducing effect between the reinforced MA or 11I fibers treated with the treatment agent of the present invention and the rubber matrix. It is believed that this prevents the wear and tear of the fibers, relieves stress, and makes fatigue less likely to occur when subjected to repeated stress.

験片の引張り強度を測定し、強度低下率を求めた。Two of the reinforcing fibers were sandwiched between rubber sheets with a thickness of 1 mm, a width of 5 mm, and a length of 300 mm, and then vulcanized at 150°C for 20 minutes.The test piece was placed in hot water at 120°C for 24 hours. MT after leaving for a while
Using a T tester, the tensile strength of the test piece was measured after applying bending stress 3000 times, and the rate of decrease in strength was determined.
