Embodiment 1

[0018] Embodiment 1: A kind of surface microporous volleyball, it comprises epidermis and liner, and liner adopts airtight strong chlorinated butyl to make, and its tensile strength reaches 1000N / cm, and it is to use nylon silk as skeleton , add 40g of yarn to the nylon filament, which is exactly the same as the ordinary volleyball liner, and the skin has a microporous structure made by adding a foaming agent. The pore structure on the skin has a pore size between 50 microns and 400 microns. Some of these micropores are fully open, that is, the two ends of the hole correspond to the inner tank and the outside, and some micropores are semi-open, that is, one end opens to the outside. One end is closed, or one end is open to the inner tank and the other end is closed, and there is a line of air bubbles in the wrapping state of the skin.

[0019] The production method of above-mentioned microporous volleyball, it is after the pickling-azodicarbonamide modified blowing agent of 3 ...

Embodiment 2

[0020] Embodiment 2: A kind of surface microporous volleyball, it comprises epidermis and liner, and liner adopts brominated butyl rubber with strong airtightness to make, and its tensile strength reaches 1050N / cm, and it is to use nylon thread as The skeleton is 35g of yarn added to the nylon filament, which is exactly the same as the ordinary volleyball liner, and the skin has a microporous structure made by adding a foaming agent. The production method of the above-mentioned microporous volleyball is to masticate 10 hours on an open mill after mixing 30 parts of boron azodicarboxylate, 60 parts of synthetic rubber, 50 parts of white carbon black and light calcium carbonate; add 5 parts of Antioxidant 264, 5 parts of activator zinc oxide and 0.4 part of vulcanization aid dibenzothiazole disulfide are added to the product obtained by masticating for 8 hours, and it is kneaded. While kneading, 2 parts of sulfur and a part of 0.2 One part of tetramethylthiuram disulfide, after ...

Embodiment 3

[0021] Embodiment 3: A kind of surface microporous volleyball, it comprises epidermis and liner, and liner adopts brominated butyl rubber with strong airtightness to make, and its tensile strength reaches 1030N / cm, and it is to use nylon thread as The skeleton is basically the same as the ordinary volleyball liner, and the skin has a microporous structure made by adding a foaming agent. The production method of above-mentioned microporous volleyball, it is after mixing 30 parts of azodicarbonamide, 30 parts of synthetic rubber, 20 parts of natural rubber, 40 parts of white carbon black, and light calcium carbonate on an open mill for plasticating for 6 hours; Add 9 parts of antioxidant 264 and 0.3 parts of vulcanization aid dibenzothiazole disulfide to the product obtained by masticating for 6 hours, knead it, and add 2 parts of sulfur and 1 part of tetrasulfide while kneading Methyl thiuram, after it is uniformly mixed as a whole, it is parked for 9 hours. The product obtain...

Abstract

The invention is concerned with a kind of structure and its produce technology of volleyball, belonging to material field. It relates to coat and inner bag, and the structure of coat has micropore made of vesicant. Mix 3 to 10 shares of vesicant, 40 to 60 shares of rubber and 30 to 50 shares of powder to reinforce function of rubber and melt on blender mill. Add with 8 to 10 shares of assistant material and 0.2 to 0.4 shares of sulfuration auxiliary agentwith the said product, mix and melt and add 2 to 3 shares of vulcanizing agent and stay for 8 hours. Melt the said product and extend as the thickness to coat of volleyball with press. Paste the coat oninner bag. The volleyball has strong bounce, perfect handle without hurting person.

Description

technical field [0001] The invention relates to a volleyball and a production method thereof, in particular to a volleyball with a microporous skin and a production method thereof. Background technique [0002] The epidermis of current volleyball is mostly hard rubber skin or leather, and the hand feeling is comparatively blunt, and it is easy to make people hit the ball red and swollen when playing, which limits people's enthusiasm for participating in volleyball, and causes injuries to sportsmen in severe cases. The Chinese patent (patent No. CN00205853.7) named as a volleyball with an independent microfiber foamed sponge layer structure is a volleyball with an independent microfiber foamed sponge layer structure, which is placed on a hollow spherical inner tube with Nylon yarn is evenly wound on the surface of the inner tube to form a nylon yarn layer, and then an independent foam sponge layer is covered on the nylon yarn layer, and the independent foam sponge can penetra...
