Tire manufacture craft its principle in the present embodiment is combined with each other to form C mainly by rubber molecule free radical --- C
The foaming and intumescing of bridge formation carrys out filled articles, and the molding of product is completed under relatively low and average pressure, due to temperature and pressure
The unstability for causing molecule is reduced, to form a large amount of nuclei of bubbles in product；These nuclei of bubbles gradually grow up generate it is micro-
Small hole.Manufactured its surface layer of solid tire or unexpanded physical layer after foaming, this is because tire-mold temperature compared with
Low, surface resin cooling is rapid, and caused by the time that nucleus is not grown up, internal softer than external to ensure, elasticity subtracts
It is more preferable to shake effect, and firmness outside is good, wear-resisting, effect is good.
Solid tire made of this technique has the following advantages：
1, accurate-size
Tire shot foamed moulding technique can be by the allowance control of product in desired interval range.Ensure that the size of product is steady
It is fixed.For the last stage of mould development, this can also reduce the modification repeatedly of mold design, be cost-effective.
2, improve and become buckling deformation
Buckling deformation is that conventional fluidization produces common one of more scabrous product defect, it be mainly product due to stress and
It shrinks uneven and generation.Since in entirely injecting foaming forming technique, product is under average pressure always.It protects
The uniform shrinkage of different location is demonstrate,proved so that this problem is addressed.
The material is after enhancing elasticity and wear-resisting, cold-resistant, pressure-resistant, askew, the resistance to on-slip of contracting, heatproof, high resistance to contraction due to transverse and longitudinal
Shrinking percentage on direction is inconsistent, therefore, when producing progress using traditional fluidisation heat pressing process, is very easy to that warpage change occurs
Shape.The deformation extent of solid article is 1.18cm, and is had using the warping part deformation that foaming obtains is injected
Apparent improvement, buckling deformation degree are only 0.18cm, compared with the former reduce about 80% or more.
3, mitigate weight
It is also obvious to inject advantage of the foaming forming technique in terms of mitigating weight.Select the masterbatch in the present embodiment
Carry out article of manufacture, which can be heavy by its under the premise of ensureing article construction intensity and elastomer great changes will take place
Amount reduces 50% or more.What different materials obtained injects the weight of foaming than the solid article made from identical material
It is low.
It is different from constructional foaming, inject that foaming structure is more regular, while the distribution of micropore is also more uniformly, for small
The product of type, inject foaming forming technique to inject speed very fast, and nucleus is all to be formed moment.Therefore, this
Slightly hole be not in people be unwilling the micropore seen fusion the phenomenon that.
It is noted that although makrolon material can obtain good fretting map, made from the material
Product will appear shock resistance and resist cold with elasticity, and resistance to complications, degree difference is without rubber performance.So not being suitable for also on the product.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, in relation to the common of technical field
Technical staff can also make a variety of changes and modification without departing from the spirit and scope of the present invention, therefore institute
There is equivalent technical solution to also belong to scope of the invention, scope of patent protection of the invention should be defined by the claims.
