Play the function of slow transition in sidewall.The triangle rubber of huge type project radial tire is divided into two kinds of sizing materials up and down.Upper bead filler with
Sidewall rubber transition, it is desirable that the flexible resistance of sizing material is preferable, heat-proof aging；Lower triangle rubber reinforced bead, to improve based on hardness,
The bonding with tyre bead and carcass is ensured simultaneously.
The sectional dimension of triangle rubber is larger under huge type project radial tire, and extrusion processability is poor, and the semi-finished product porosity is big,
Influence tire material distribution, off-design standard.Huge type project radial tire vulcanization time is long, and this requires lower triangle rubber exists
Physical mechanical property can be kept after vulcanizing for a long time.
In order to reach the design requirement and performance of above-mentioned lower triangle rubber, by adding in carbamic acid class tree in formula
Fat UF410 reduces the semi-finished product porosity, improves vulcanizate hardness；Add in reinforced resin and curing agent improve its crosslink density and
Hardness and sulfuration resistant reproducibility；It adds in cobalt salt adhesive hardening, increase bonding；Add in the process safety that antiscorching agent improves sizing material
Property.
