Problems solved by technology

Among them, the first three models cannot give an explicit expression of the degree of vulcanization. In order to overcome this defect, the latter two models are proposed
But so far there is no model that can accurately describe the vulcanization kinetics of rubber as a whole.

Abstract

The invention discloses a method for simulating the vulcanization process of a rubber product, which comprises the following steps of: measuring a rubber flow curve and thermal physical parameters through tests; establishing a hybrid dynamic model and a thermal physical function of the rubber; establishing a heat transfer-chemical reaction coupled equation of the rubber product; performing numerical calculation on the equation based on a Newton iteration method; and acquiring at least one physical parameter related to the rubber product model. The method can more accurately simulate the heat transfer process and the crosslinking process of the rubber vulcanization.

Description

technical field [0001] The invention relates to a method for simulating a rubber vulcanization process. The method can simulate the heat transfer and crosslinking reaction state of a rubber product vulcanized at a certain temperature, and accurately calculate the temperature and vulcanization degree changes of each point inside the rubber product. Background technique [0002] The traditional method of researching rubber vulcanization is to measure the temperature history at key points inside the rubber product through thermocouples, and then apply a reasonable kinetic model to convert the temperature of each point into the degree of vulcanization, so as to determine the necessary time for vulcanization. However, changes in formulation design and vulcanization medium temperature will affect the vulcanization chemical reaction, which in turn will affect the final crosslink density and mechanical properties of the rubber. And after each test, the rubber part must be cut to fin...
