Problems solved by technology
The complex vulcanization reaction inside the tire makes the distribution of vulcanization characteristic parameters obvious inhomogeneity and time-varying, and there are many factors affecting tire vulcanization, which leads to blindness in the design of tire vulcanization system
Especially in the face of complex vulcanization objects such as multi-layer thick-section radial tires, it is difficult to reasonably match the vulcanization system between different internal rubber materials

The invention provides a designing method of a tire stock vulcanization system. The designing method comprises the steps of first, counting the variation range of thermophysical parameters and vulcanization dynamic parameters of a tire; then, establishing a tire vulcanization process numerical model, and carrying out orthogonal testing on the thermophysical parameters and vulcanization dynamic parameters respectively to determine the schema of relation between project positive vulcanization time and the thermophysical parameters and the vulcanization dynamic parameters and the primary and secondary sequence of influence of the thermophysical parameters and the vulcanization dynamic parameters on the positive vulcanization time; finally, selecting the main influencing factor of the positive vulcanization time, and adjusting the numerical value of the main factor according to the relation schema of the project positive vulcanization time and the main influencing factor to design the vulcanization system. The blindness of design of the tire stock vulcanization system is reduced, reasonable matching between different stocks and different vulcanization systems in the tire is realized, the tire vulcanization efficiency is improved, the development expense is reduced, the research and development cycle is shortened, and the thicker the fracture surface of the tire is, the more the layer number of the stock is, and the more effective the method disclosed by the invention is.
Description
technical field [0001] The invention relates to a design method of a tire rubber vulcanization system. Background technique [0002] The tire is a circular elastic product composed of multiple layers of rubber and rubber cord composite materials. The functions of each layer are different, and the vulcanization system of the rubber formula is also different. In order to improve the tire vulcanization efficiency, it is necessary to reasonably match the vulcanization system of different rubber materials in the tire. The rubber vulcanization system includes vulcanizing agents, accelerators, activators, and anti-scorch agents. By adjusting the vulcanization system, parameters such as rubber density, specific heat capacity, thermal conductivity, activation energy, and frequency factor can be relatively independently controlled within a certain range. [0003] Vulcanization is the last process in tire manufacturing and determines its final performance. The complex vulcanization r...
