Embodiment 1
[0028] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises wheel hub 5, hub plate 6, reinforcing rib 4, tread 1, inner tube 3 and filler 2 between tread 1, inner tube 3, tread 1, inner tube 3 adopt casting type polyurethane elastomer, belt The beam layer is four layers, which is composed of three layers of steel cords and a layer of aramid fibers compounded by adhesives. The carcass ply is composed of steel cords and aramid fibers. The inner lining layer is composed of chlorinated butyl rubber and steel cords. Layer composite; the filler is composited with the following two polyurethanes: one is a polyurethane elastomer with a hardness of Shore A45, and the other is a self-skinned polyurethane foam elastomer.
[0029] The manufacturing process of this product is as follows:
[0030] 1. Clean the surface of the rim:
[0031] 1) Surface treatment of metal rims, sandblasting; not only the surface of the rim but also the 10mm...

Abstract
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.
Description
(1) Technical field [0001] The invention relates to a large load-bearing tire, in particular to a large-scale load-bearing polyurethane composite material tire and a production method thereof. (2) Background technology [0002] In recent years, we have conducted detailed research on units that use large heavy-duty tires, such as Shendong Group, Pingshuo Coal and Electricity, Jincheng Mining Group, Datong Mining Group, Yankuang Group, Komatsu Shantui Co., Ltd., Xugong Group, Tianjin Hong Kong transportation companies, etc. found that the large heavy-duty tires they use are generally imported, mainly divided into two categories, one is solid tires, and the other is filled tires, and the materials used are mainly rubber (such as natural rubber, styrene-butadiene rubber, Butadiene rubber, etc.), because of its low load resistance, low abrasion resistance, low tear strength and poor puncture resistance, it has short life and poor safety performance. For example, the tires of lar...
