Performance, while can also widen the application range of finished ball.
Embodiment 11
The present embodiment provides a kind of vollyball, tire in the foaming for selecting embodiment 1 or 2 to provide sticks crust and is made.This implementation
Tire is 90~115g using liner, liner weight is thickeied in the foaming of the vollyball of example, and thickness is in 0.4mm or so.The identical material of tradition
The vollyball liner of matter, weight is generally in 80~90g, and thickness is in 0.3mm or so.Vollyball provided in this embodiment is able to achieve liner and adds
Thickness, to improve liner air-tightness.
Vollyball weight provided by the embodiment can control in the weight range required at 260 grams~280 grams, and middle tire weight exists
180 grams~190 grams, under the premise of guaranteeing weight demands, moreover it is possible to realize the thickening to vollyball liner, improve liner air-tightness.
Tire in the foaming made compared with prior art is bonded blown rubber material on yarn or patch, then in vulcanizing mold sulphur
To change, foaming rubber layer is interpenetrated with thread layers or patch layer in sulfidation, and it is soft interior hard outside tire in the foaming produced,
It is obviously partially hard compared to middle tire of the invention to pat the feeling touched.The present invention is due to the bubble that is directly sticked in thread layers or patch layer
Cotton layer, the not constraint of intermediate rubber layer, sphere spring and pliability are more preferable；And in yarn or patch or its compound layer surface
Foam is sticked, is able to maintain yarn or patch and the original flexibility of foam, it is more soft comfortable that sense is touched in beating.Foam is used simultaneously
Layer substitution blown rubber in plies, the sulfuration process of tire in the production process in blown rubber can be saved, at the same also it is avoided that
The higher bad and foaming non-uniform phenomenon generated in sulfidation.And since the foaming hole of foam itself is conducive to glue
The step of infiltration is adhered to, and can also remove polishing from.
It is sticked for needs and obstructs the basketball or rugby of line, since stalk line is sticked in foamed cotton layer or is sticked by patch
Foam surface, and obstruct line using synthesis PVC, PU, the materials such as fiber, compared to the foaming on existing in the blown rubber tire surface of being sticked
Rubber mass obstructs line, since blown rubber density is low, so leakage part and air, the easy aging cracking of sun exposure, and intolerant to
Mill.The present invention synthesizes the non-aging cracking of stalk line sun exposure of PVC, PU, the materials such as fiber, and when use is more wear resistant, uses the longevity
It orders longer.
In the foaming made compared with prior art tire due to the stability of raw material it is inadequate, and need in vulcanization to touch interior progress
Vulcanization reaction, technical conditions require defective products that is high, and generally having 10%-25%, once raw material is unstable or dnockout process
In there is some deviations or sulfurizing mould temperature deviation, can all cause foaming uneven or foam not rise, vulcanizing to touch out can not just draw
It returns, causes defective products, so the market price is high, the producer for production of having the ability is limited, and occupation rate of market is relatively low.Hair of the invention
Foamed cotton layer is that the foamed cotton layer fitting foamed is got on just to tire in the production process in bubble, will not generate defective products, cost
It is low, be conducive to market application.
Need to be arranged on foamed cotton layer the situation of dividing line or groove for embodiment 8, operation and manufacturing process are also simpler
It is single, it may be implemented to set dividing line on foamed cotton layer or groove stick again, tire opens up recessed in the foaming of the prior art
Slot is needed to opening up special sulfurizing mould.
In addition, mostly important is a bit, the characteristics of being based on foamed cotton layer light weight, the tire situation in the foaming of equivalent weight
Under, especially tire in the foaming of basketball can aggravate bladder layer, for the liner of identical material and model, be equivalent in capable of thickening
The thickness of gallbladder, to improve liner air-tightness；The characteristics of being equally based on foamed cotton layer light weight, tire is also in the foaming of structure of the invention
It can apply to production quality and require tire in the foaming of lighter vollyball, while the liner of vollyball can also be thickeied, improve the gas of vollyball
Close property；And can be suitably used for tire in foaming of the production with the liner of complex structure, it will not be because of the quality of labyrinth
Increase and cannot achieve the requirement of sphere weight.
The above is a specific embodiment of the invention, but any restrictions cannot be constituted to the present invention, therefore need special
It points out, it is all based on the present invention, it is made any modification and is all fallen within the scope of the present invention with improvement.
