Example Embodiment

[0018] Example 1: A surface microporous volleyball, which includes a skin and an inner bladder. The inner bladder is made of chlorinated butyl with strong air-tightness, and its tensile strength reaches 1000N / cm. It uses nylon silk as the skeleton , 40g of yarn is added to the nylon yarn, 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 epidermis has a pore size ranging from 50 microns to 400 microns. Some of these micropores are all-through, that is, the two ends of the hole correspond to the inner tank and the outside respectively, and some of the micropores are semi-through, that is, one end opens to the outside. One end is closed, or one section is open to the inner liner and one end is closed, and there is a row of air bubbles in the state of being wrapped by the skin.

[0020] Example 2: A surface microporous volleyball, which includes a skin and an inner bladder. The inner bladder is made of bromobutyl rubber with strong air-tightness, and its tensile strength reaches 1050N / cm. It is made of nylon yarn. For the skeleton, 35g of yarn is added to the nylon filament, which is exactly the same as the ordinary volleyball liner. The skin has a microporous structure made by adding a foaming agent. The above-mentioned microporous volleyball production method is to mix 30 parts of boron azodicarboxylate, 60 parts of synthetic rubber, 50 parts of white carbon black, and light calcium carbonate and masticate on an open mill for 10 hours; add 5 parts Antioxidant 264, 5 parts of activator zinc oxide and 0.4 parts of vulcanization assistant dibenzothiazole disulfide are added to the product obtained by plasticizing for 8 hours, mixing them, and adding 2 parts of sulfur and one part of 0.2 while mixing One part of tetramethylthiuram disulfide, wait for the who...

[0021] Example 3: A surface microporous volleyball, which includes a skin and an inner bladder. The inner bladder is made of bromobutyl rubber with strong air-tightness, and its tensile strength reaches 1030N / cm. It is made of nylon yarn. The skeleton, which is basically the same as an ordinary volleyball liner, has a microporous structure made of foaming agent. The above-mentioned microporous volleyball production method is to mix 30 parts of azodicarbonamide, 30 parts of synthetic rubber, 20 parts of natural rubber, 40 parts of white carbon black, and light calcium carbonate, and masticate on an open mill for 6 hours; Add 9 parts of antioxidant 264 and 0.3 parts of vulcanization assistant dibenzothiazole disulfide to the product obtained by plasticizing for 6 hours, mix it, and add 2 parts of sulfur and 1 part of tetrakis disulfide while mixing. Methyl thiuram, wait for the whole mixture to be evenly mixed and then park for 9 hours. The product obtained from the park for 9 hours...

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...
