Embodiment 1

[0026] A bladder rubber, which comprises the following components by weight percentage: 45% bromobutyl rubber, 20% carbon black, 15% talcum powder, 5% oil, 2% anti-aging agent, 3% vulcanizing agent, The rest is 10% of additives commonly used in the rubber field, and commonly used additives are mainly stearic acid and processing aids.

[0027] Bladder rubber uses brominated butyl rubber as the main raw material. Since brominated butyl rubber is an isobutylene-isoprene copolymer elastomer containing active bromine, it has a basically saturated main chain of butyl rubber, so it has butyl rubber. The unique characteristics of polymers, such as good air tightness, high mechanical strength, low permeability, excellent aging resistance, etc.; at the same time, the active bromine on the molecular chain endows it with wider vulcanization characteristics and faster The vulcanization rate is high; and the raw rubber Mooney is low, which ensures good mixing characteristics and excellent m...

Embodiment 2

[0039] The rest are the same as in Example 1, except that the bladder rubber includes the following components in weight percent: 60% brominated butyl rubber, 30% carbon black, 5% talcum powder, 1% oil, and 1% antioxidant , vulcanizing agent 1%, and the rest is 2% commonly used additives in the rubber field. Commonly used additives are mainly stearic acid, processing aids, etc.

Embodiment 3

[0041]The rest are the same as in Example 1, except that the bladder rubber comprises the following components in weight percent: 48% bromobutyl rubber, 21% carbon black, 14% talcum powder, 4.5% oil, 1.9% antioxidant , vulcanizing agent 2.8%, and the rest is 7.8% commonly used additives in the rubber field. Commonly used additives are mainly stearic acid and processing aids.

Abstract

A bladder rubber and its preparation method are provided. The bladder rubber contains brominated butyl rubber 45-60, carbon black 20-30, talcum powder 5-15, oil material 1-5, anti-aging agent 1-2, and vulcanizing agent 1-3 wt%. The inventive bladder rubber has performances of butyl rubber and active bromine, effectively improves gas tightness of bladder, accelerates vulcanizing speed, ensures adhesion property, and improves service life of bladder.

Description

technical field [0001] The invention relates to a rubber, in particular to a bladder rubber and a preparation method thereof. Background technique [0002] Ball bladder is the core component of ball equipment, and its interior is filled with gas. Whether the gas inside the bladder is saturated or not affects the elasticity of the ball equipment. Therefore, in the process of production and use, the airtight performance of the bladder plays a crucial role. important role. [0003] The traditional bladder uses ordinary natural rubber as the main material. Although it can meet the general requirements of use, due to the poor airtightness of natural rubber and the low pressure holding capacity of the product, it needs to be frequently replenished with gas, or use butyl The rubber material used to produce bladders has good air tightness, but the rubber material has a slow vulcanization speed, poor adhesive performance, prone to problems such as bagging and delamination, and the s...
