Embodiment Construction

[0006] The following specific embodiments further illustrate the present invention.

[0007] The technical scheme adopted by the present invention is: a foamed basketball inner tube. The inner tube is formed by kneading, sheeting, splicing, and then vulcanizing the colloid. It is characterized in that the mixing ratio of the colloid is 0.35. Phr of butyl rubber is 25-40, phr of butyl rubber is 75-80; phr of carbon black is 30-40; phr of light calcium is 22-28; phr of live calcium is 40-45; phr of talc is 15 -20; oil phr is 8-10; zinc oxide phr is 5-7, stearic acid phr is 0.8-1.1, antioxidant phr is 1-2, wax phr is 1-1.3; sulfur phr is 2.4-2.6; promotion The agent phr is 4-5.

[0008] The invention has the advantages of simple process, better air tightness, springability, strength and impact wear resistance.

[0009] The weight value of each component in a gel is the product of its phr value and the mixing times value. If the phr of smoked glue is 40, its weight is 40*0.35=14kg.

Abstract

The invention discloses a foaming basketball inner tube. The inner tube is prepared by a colloid which is subjected to mixing, discharging sheet, splicing molding, and shaping by vulcanization processing. The colloid accounts for 0.35 of the outer skin, wherein the colloid comprises 25-40 phr of smoked offset print, 75-80 phr of a butyl rubber, 30-40 phr of carbon black, 22-28 phr of light calcium, 40-45 phr of activated calcium, 15-20 phr of a talcum powder, 8-10 phr of oil, 5-7 phr of zinc oxide, 0.8-1.1 phr of stearic acid, 1-2 phr of an antioxidant, 1-1.3 phr of wax, 2.4-2.6 phr of sulphur and 4-5 phr of an accelerant. The foaming basketball inner tube provided by the invention is better than the same kind products in gas tightness, bounce performance and intensity.

Description

Technical field [0001] The invention relates to a basketball article, in particular to a foamed basketball inner tube. Background technique [0002] The existing basketball inner tube is made of natural rubber, and its disadvantages are poor air tightness and poor bounce. Problems such as air leakage and inelasticity are prone to occur during use, and the cost of using natural rubber is also high. Summary of the invention [0003] In order to solve the above technical problems, the technical solution adopted by the present invention is: a foamed basketball inner tube. The inner tube is formed by kneading, sheeting, splicing, and then vulcanization processing. It is characterized in that the rubber is mixed The multiplier value is 0.35, where the phr of smoked gum is 25-40, the phr of butyl gum is 75-80; the phr of carbon black is 30-40; the phr of light calcium is 22-28; the phr of live calcium is 40-45; phr of talc is 15-20; oil phr is 8-10; zinc oxide phr is 5-7, stearic a...
