The invention discloses a large
truck tire, in particular a large
truck tire of
polyurethane composite and a production method thereof. The tire of
polyurethane composite comprises a wheel hub, a wheel hub board, a tire
tread, an inner tube, and a filler between the tire
tread and the inner tube. The invention is characterized in that the tire
tread and a tire sidewall adopt
casting polyurethane elastomers; a tread bracing layer is provided with four
layers which are compounded from three
layers of steel wire cords and a layer of
aramid fibers through
adhesive; a tire body cord layer is compounded from steel wire cords and
aramid fibers; an inner liner layer is compounded from a chlorinated
butyl rubber and a steel wire cord layer; the filler adopts at least one of the following two elastomers: a
polyurethane elastomer with
Shore hardness of A 45 and a polyurethane foaming
elastomer with self crust. The invention has the advantages of
wear resistance, low temperature performance, better elastic performance under high
hardness, better uniformity of
colloid due to
fully automatic casting technology, more stable performance,
tear resistance, strong performance of pealing resistance, and non
pollution from three wastes during manufacturing; the invention belongs to a green manufacture technology.
