Abstract

A two-layer leak-proof ball comprises a sheath layer (1), an intermediate body layer (2), a winding yarn layer (3), an inner body layer (4) and a two-layer protective layer (5). The intermediate body layer (2), the winding yarn layer (3), the inner body layer (4) and the two-layer protective layer (5) are tightly set successively at the inside of the sheath layer (1). Also disclosed is the manufacturing method of the two-layer protective layer (5) of the two-layer leak-proof ball. High air-sealed bromide butyl mucilage is injected at the inside of the inner body layer (4), and vulcanized at low temperature, thus a glue film is formed at the inner wall of the inner body layer (4). The inner bag of the two-layer leak-proof ball has high tightness and long service life.

Claims

1. A new type two-layer leak-proof ball, comprising a sheath layer (1), an intermediate body layer (2), a winding yarn layer (3) and an inner body layer (4), wherein the new type two-layer leak-proof ball further comprises a two-layer protective layer (5);

the intermediate body layer (2), the winding yarn layer (3), the inner body layer (4) and the two-layer protective layer (5) are tightly set successively at the inside of the sheath layer (1).

2. The new type two-layer leak-proof ball as recited in claim 1, wherein high air-sealed bromide butyl mucilage is employed as the two-layer protective layer (5).

3. A manufacturing method of the new type two-layer leak-proof ball according to claim 1 or 2, wherein high air-sealed bromide butyl mucilage is injected at the inside of the inner body layer (4);

the bromide butyl mucilage comprises substances of the following weight portions;

40-60 portions of glue formed by bromide butyl rubber with a weight percentage of 80%-100% and natural rubber with a weight percentage of 0%-20%, 40-60 portions of ultrafine particle size carbon black with a particle size that residues on a 325 mesh sieve are no more than 0.1% and served as a reinforcer, and 1-5 portions of rubber vulcanizing system curing agent;

moreover, the bromide butyl mucilage is injected into the inner body layer (4) to rotate and flap simultaneously for 20-30 minutes via a method similar to Super Lotto Ernie high-speed rotation, so that the bromide butyl mucilage is evenly dispersed to an inner wall, fills and reinforces the inner wall and is tightly adhered on the inner surface of the inner body;

after the substances of the above weight portion ratio are mixed into the bromide butyl mucilage, the bromide butyl mucilage is baked in an 40-60 DEG C. oven via a low temperature vulcanizing system, and vulcanized for 12 h, so that a glue film has high tightness after the bromide butyl mucilage is vulcanized.

4. The manufacturing method of the new type two-layer leak-proof ball according to claim 3, wherein high air-sealed bromide butyl mucilage is injected at the inside of the inner body layer (4);

the bromide butyl mucilage comprises substances of the following weight portions;

50 portions of glue formed by bromide butyl rubber with a weight percentage of 80% and natural rubber with a weight percentage of 20%, 45 portions of ultrafine particle size carbon black with a particle size that residues on the 325 mesh sieve are no more than 0.1% and served as a reinforcer, and 5 portions of rubber curing agent;

moreover, the bromide butyl mucilage is injected into the inner body layer (4) to rotate and flap simultaneously for 20 minutes via a method similar to Super Lotto Ernie high-speed rotation, so that the bromide butyl mucilage is evenly dispersed to an inner wall, fills and reinforces the inner wall, and is tightly adhered on the inner surface of the inner body;

after the substances of the above weight portion ratio are mixed into the bromide butyl mucilage, the bromide butyl mucilage is baked in a 40-60 DEG C. oven via a low temperature vulcanizing system, and vulcanized for 12 h, so that a glue film has high tightness after the bromide butyl mucilage is vulcanized.

5. The manufacturing method of the new type two-layer leak-proof ball according to claim 4, wherein high air-sealed bromide butyl mucilage is injected at the inside of the inner body layer (4);

the bromide butyl mucilage comprises substances of the following weight portions;

50 portions of bromide butyl rubber with a weight percentage of 100%, 45 portions of ultrafine particle size carbon black with a particle size that residues on a 325 mesh sieve are no more than 0.1% and served as a reinforcer, and 5 portions of rubber curing agent;

moreover, the bromide butyl mucilage is injected into the inner body layer (4) to rotate and flap simultaneously for 30 minutes via a method similar to Super Lotto Ernie high-speed rotation, so that the bromide butyl mucilage is evenly dispersed to an inner wall, fills and reinforces the inner wall and is tightly adhered on the inner surface of the inner body;

after the substances of the above weight portion ratio are mixed into the bromide butyl mucilage, the bromide butyl mucilage is baked in a 40-60 DEG C. oven via a low temperature vulcanizing system, and vulcanized for 12 h, so that a glue film has high tightness after the bromide butyl mucilage is vulcanized.
