All-steel radial tyre and preparation method thereof

Abstract

The invention provides all-steel radial tyre. The all-steel radial tyre comprises the components in parts by weight: 16.5 parts of butylbenzene resins, 10 parts of rubber powder, 3.5 parts of zinc oxide, 3.0 parts of stearic acid, 1.0 part of a rubber anti-aging agent RD, 10 parts of reinforcing resins, 100 parts of natural rubber STR20, 50 parts of carbon black N375, 4.7 parts of aromatic hydrocarbon oil, 10 parts of high styrene resins, 1.0 part of microcrystalline wax, 2.74 parts of insoluble sulfur, 1.0 part of a rubber accelerator DZ, 1.0 part of a rubber accelerator HMT, 0.4 part of a rubber anti-scorching agent CTP and 50.2 parts of small powder. According to a raw material preparation unit, a rubber compound unit, a semi-finished part unit, all part molding rough tyre units and a rough tyre vulcanization unit, the all-steel radial tyre is manufactured. The all-steel radial tyre has the advantages that in the manufacturing process, the viscosity of the materials is moderate, winding cloth is convenient to separate so as to avoid the adhesion phenomenon of winding parts, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to an all-steel radial tire and a preparation method thereof. Background technique [0002] The traveler is the part where the tire contacts the rim, and the traveler wrapping cloth is an important part connecting the apex rubber core and the traveler. The viscosity of this part and the coating rate of the pressing line are extremely important. If there is a problem in this part, it is easy to cause quality problems such as tire three-line cracking, sub-port explosion, and carcass spinning explosion. [0003] The formula rubber compound for traveler wrapping has special requirements in its processing process. The workshop has strict requirements on its use. It can be summed up as "it can't be non-sticky, and it can't be too sticky", so the quality control of technicians is put forward. higher requirements. If the parts are not sticky, the adhesion between the traveler a...

AI Technical Summary

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide an all-steel radial tire and its preparation method in view of the deficiencies in the prior art. The adjustment effectively solves the problem that during the winding process of the bead ring during tire manufacturing, the viscosity of the material is high, the winding cloth is difficult to unwind, and even the adhesion cannot be unwound, the production efficiency is low, and some materials are wasted due to the adhesion.
